If you’re seeing any, you’re not fapping hard enough. ;)\n\n---\n\nPart 1: Impregnation\n\nShe had been told not to leave the group for any reason. Outside the city walls, one had no idea where Ferals might be lurking, and no one went out there without an armed escort. The two professors and twenty or so biology students on this scientific excursion had been accompanied by five guards with autorifles, and some of her fellow students who were qualified had personal weapons, too.\n\nXyla did not; guns scared her. What was more, anyone who had a firearm was expected to shoot Ferals on sight, and she didn't think she could kill a living thing, even if it was something as frightening and monstrous as a Feral. It was hard to believe that they were related to Civils; no wonder the Civils had walled themselves off from their fellow lupinoids more than a millennium ago.\n\nBeing new to the biology program, Xyla had no friends in the group. There were several familiar faces from class, but no one she had actually talked to much. She had never had much in the way of social skills. Thus, while the others clustered around various plants and flowers of interest, Xyla backed away to the edge of the clearing, casting around for some sort of flora that she could study by herself.\n\nThe hands that grabbed her from behind took her completely by surprise. They pulled her into the thick foliage around the clearing, and before she could scream, one of them shoved some sort of rough rag into her mouth. Another pair of hands tied a second rag tightly around her muzzle to keep it closed on the first rag. Then, quickly, two male forms picked her up and carried her away from the clearing, through the dense trees.\n\nThrashing around in a vain effort to escape, Xyla couldn't clearly see her assailants. But they had to be Ferals.\n\nThey arrived at another clearing several hundred yards away, where three more Ferals were waiting. They, too, were males, and naked. Each was holding one or two pieces of rope.\n\nNone of them said a word as they tied her spread-eagle on a tree stump that was nearly as large in diameter as she was tall. Each of her limbs was lashed to one of four saplings growing around the stump. Then, making no noise beyond a low grunt, the Ferals tore her clothing from her like it was paper.\n\nThe first of them approached her, holding his huge erection in his hand. Xyla wasn't very sexually experienced--in fact, she had only ever had sex once, with a short-term boyfriend, and she had not enjoyed it--but she knew most Civil men's penises were not nearly that big. It was nearly a foot long, and three inches wide. The knot at the base was wider still.\n\nThe Feral saw the way she was looking at his cock, and he stroked it gently, like it was a beloved pet. Then, with his free hand, he fondled her bare pussy as she squirmed helplessly. He was smearing something greasy inside her lips.\n\n\"Cunt,\" he growled with anticipation as he opened her wider with his hand.\n\n\"Nnnnnnnn!\" Xyla screamed into her gag as the Feral placed the head of his monstrous member between her cunt folds. Ignoring her protests, he mounted her and began to push his massive wolf-penis into her. She screamed into the gag, harder than she had ever screamed in her life, as inch after inch after inch of cock was forced into her body, into her cunt, practically into her womb.\n\nHe didn't bother with preliminaries. Teeth bared, he fucked her hard and deep, every single shove battering her cervix as she screamed and screamed into her gag. The pain was unbelievable, worse than losing her virginity had been. She would have done anything to make him stop, but she was helpless even to speak, let alone move.\n\nEven when he came it hurt, burning her insides like he'd poured molten plastic into her. She could actually feel it in her vulva, in her womb.\n\nThere was one small mercy—he did not knot her, which she believed would have torn her apart. Rather, he got off of her quickly, and another took his place. In the brief moment between mountings, she could see that the other Ferals were slowly masturbating, as if warming up for their turn. Now she knew she was in for a lot more rape, and she began crying.\n\nThey took her, one after another, until they had all had a turn, and then they started again. She alternately screamed, cried, and mindlessly begged through her gag as cock after cock violated her roughly and deeply, again and again, each time pouring another searing load of cum into her unprotected womb.\n\nAfter nearly an hour, the Ferals were all spent. They untied her and, as they departed, one of them looked at her and pointed in the direction (she thought) of the clearing from which they had taken her. Then they vanished into the trees.\n\n***\n\nShe returned to the clearing, staggering and clad in the shreds of her clothes. She made some excuse about falling down a hill covered in brambles, but it was clear that everyone knew what had happened to her. The entire group immediately packed up and returned to the City.\n\nXyla couldn't bear the shame--not just of what happened, but of everyone knowing, or at least suspecting. She refused medical treatment and went straight home, where she showered and showered and took massive doses of analgesic for the pain. As soon as she was numb enough to move around without agony, she began to pack her belongings. Fortunately, she didn't have terribly many.\n\nIt was a near certainty that someone on the field trip had reported the incident, so it wouldn't be long before she got a visit from the authorities. The very last thing she wanted was to tell anyone about what had happened, or to be poked and probed by doctors. And if she was pregnant, the consequences would be even worse. \"Feral-induced pregnancies\"--perhaps the euphemism of the century--were extremely rare, but by law, they had to be terminated. Xyla could never do that; what had happened to her was horrible, but even if they had put a baby in her, that wasn't the baby's fault.\n\nSo she moved out that very night, stayed in a motel on the other side of the City, and sought a new home in the morning. For all her lack of interpersonal skills, Xyla knew what she was doing online; she quickly set up a new identity for herself, far away from any part of the City where anyone might know her.\n\n---\n\nPart 2: Hunger\n\nBefore long, it became clear that Xyla was indeed pregnant. But this was not a normal pregnancy; by the time she was certain that her periods had stopped, about a month and a half after the rape, she was already starting to show.\n\nShe was afraid to seek any prenatal care, and she was afraid not to. So she just went a few times, finding a different doctor each time and promptly erasing any record of her visits. Three months into her pregnancy--when she looked to be about seven months along--she learned that she was to have twins, a boy and a girl.\n\nOne other abnormal aspect of her pregnancy was the substantial growth of her breasts. She had expected some of that, of course, but not to go from a small B cup to a full C in the space of two months. She didn't like it; she had never wanted to stand out in that way.\n\nJust over four months after her forcible impregnation, she delivered the twins at a private hospital, where she paid for her care in cash with some of the money her late father--a distant man in life but generous in death--had left her. Not being close to her family, she simply chose names she had always liked the sound of: Yori for the girl, and Zeryn for the boy.\n\nThe first exceptional thing she noticed about the twins was their hunger. The babies usually took nearly twice the normal amount of time to feed, sucking hard--often painfully hard--the entire time. Seemingly in response to this demand, her breasts grew more, expanding to what Xyla considered an obscene size. She hated the way people, especially men, looked at her and her D-cup breasts when she had to leave the house to do some errand. Fortunately, that was rarely necessary; she could do her online job from home, and she had groceries and other supplies delivered.\n\nThe next thing she noticed was that the twins' development was just as rapid now as it had been [i]in utero[/i]. By five months, they were walking like the one-year-olds they appeared to be. They learned to talk at eleven months, by which time they appeared to be at least two years old. Xyla was forced to move apartments twice just to keep people from noticing.\n\nAnd still they breast-fed with unnatural, even ferocious hunger. Attempts to switch them to bottle-feeding were futile; they would scream and cry nonstop--once for an hour straight--until they got the breast milk they craved, directly from the source. Only gradually was she able to get them to eat SOME solid food, and even so, they still screamed if they did not get at least one breastfeeding a day.\n\nNot only did the twins refuse to be completely weaned, but they had very strong preferences about the feeding process itself. By the time they were two (and looked at least four), they had an established ritual: They always did it in Xyla's bedroom, with Xyla lying on her back in bed, wearing panties and an open robe, and each child straddling one of her thighs as he or she sucked powerfully on Xyla's nipples.\n\nOne night, while the twins were feeding, Xyla felt a hardness moving against her thigh. She looked down and saw Zeryn very slowly hunching his hips against her naked skin. The sight and feel of it disgusted her, but she said nothing.\n\nThe next night, however, when dinner was nearly over, she addressed the twins at the kitchen table.\n\n\"You have both gotten old enough that it's not appropriate for you to breastfeed anymore. From now on, no more feedings at bedtime. Your dinner should be enough.\"\n\nThe twins looked shocked. \"But mommy,\" Yori protested, \"we get so hungry at night!\"\n\n\"If you really need something,\" Xyla said, \"you can get a snack from the refrigerator.\"\n\n\"But we NEED your milk, mommy!\" Zeryn cried. \"Nothing else is the same!\"\n\nBefore Xyla could even reply, both twins stormed out of the kitchen and into their room, slamming the door behind them.\n\nIt's fine, Xyla told herself. They just need a little time to calm down and adjust to the idea.\n\nThey didn't emerge from their room until their bedtime, so Xyla opened their bedroom door and said, \"Time for bed now.\" Strangely, though, the twins were already in bed, each of them looking at a book. Neither said anything to Xyla.\n\n\"Good night,\" she said as she closed their door. There was no reply.\n\nXyla went to her room and, just to be sure, locked the door.\n\nFor the first time in a long time, Xyla put on a nightgown. Wearing it felt like a relief.\n\nAbout twenty minutes later, just after Xyla had turned out the light and closed her eyes, she heard someone trying the door handle--once, then again, then harder, shaking the door.\n\n\"Let us IN!\" she heard Zeryn shout.\n\n\"We're HUNGRY!\" Yori cried.\n\n\"No!\" Xyla shouted nervously. \"We're not doing that anymore! Go back to bed!\"\n\nBut the twins would not be deterred. They banged on the door nonstop for a full minute, then two, then five.\n\n\"Stop it!\" she shouted through the door, but the banging continued without pause.\n\nFinally, she flung the door open, ready to scream at the children to stop. Their bodies slammed into the door; the edge of it clipped her head and knocked her down.\n\nBefore she could get up, the twins were on her. Between the two of them, they were strong enough to rip her nightgown down the middle, forcibly exposing her breasts. They leaped onto her thighs, pinning her down, and began sucking hard, harder than ever before, biting, bruising, hurting her, punishing her.\n\nShe tried pushing them off, even hitting them on their backs, but they were ferocious in their determination to feed. Nothing would stop them.\n\nFinally, when they had had their fill, they left their sobbing mother on the floor and returned to their room.\n\n---\n\nPart 3: Want\n\nBreastfeeding resumed as usual the next night. Xyla knew she had failed as a mother; if she had weaned them a year ago, none of this would have happened. Now, it was just easier to give them what they wanted. Surely, they would grow out of it eventually. Every child did, didn't they?\n\nAfter that, every night when she lay down in bed and opened her robe for them, she would feel Zeryn's erection grow as he nursed on her, and he frequently would work it slowly against her thigh as he sucked at her tit. And soon, Yori began to do the same, rubbing her crotch against Xyla's other thigh while she nursed, leaving it damp afterward. The whole thing disgusted Xyla, but there was nothing she could do. She had lost control of the situation.\n\nThis went on for several months. As before, the children continued to grow at more than double the normal rate, and Xyla was forced to move to yet another new apartment in distant part of the City and enroll her children in school. She really didn't want to, but the law required that children over six years old attend, and no doubt someone would report the twins as truant if they were seen in the apartment or outside during the school day.\n\nThat went fine for a little while. Despite their chronological age, the children had no trouble keeping up with schoolwork. Social life was another matter, however. The twins tended to keep to themselves and would react strongly--sometimes violently--if one of their peers teased them for it. Xyla expected to have this problem with Zeryn, but it was just as bad with Yori, if not worse. She was mainly hostile toward other girls, especially any who tried to tell her what to do. Early in the year, Yori received a two-day suspension for beating up a girl who had accused her of cutting in line for the water fountain.\n\nOne day, about four months into the school year, the principal called her in, not saying what it was about until Xyla was seated in her office. She asked whether the children had problems at home, and whether Xyla had anyone else living with her besides the twins. Xyla said no.\n\n\"It seems,\" said the principal, \"that Zeryn and Yori followed one of their classmates, a girl, into the washroom, and they...well, they made her take off her clothes, and they...abused her. Fondled her, I mean.\"\n\n\"A-are you sure?\"\n\n\"The girl's description of the...incident...was very specific. She said, among other things, that Yori held her against the wall while Zeryn touched her.\"\n\nXyla was speechless. She wished she couldn't believe it, but there was nothing she could believe more easily.\n\n\"The girl’s parents,\" the principal continued, \"have promised to refrain from legal action--against you AND the school--if you withdraw your children immediately.\"\n\nAnd that was that. Xyla moved them again, established new identities, and started over once more.\n\n***\n\nThey were getting bigger, and stronger. Now, at night, she felt the wiry strength in their hands when they held her--by the arm, the wrist, even the throat--as they suckled fiercely at her breasts. Even though she made no attempt to stop them or escape, they seemed to instinctively want to pin her down, to control her.\n\nShe was frightened of them. And she didn't know what was worse--the fear, or the shame she felt at being afraid of her own children.\n\nThen, just when she thought it couldn't get any worse, it did.\n\nHer children were four years old now, but they looked and acted as if they were nine. They were enrolled in school again and were keeping up with their studies somehow, even though they had missed half the education a normal, Civil child would have had by their apparent age. And, thankfully, they seemed to be keeping their hands to themselves--at school, anyway.\n\nAt home, however, the nightly breastfeeding hadn't stopped; it had only grown more degrading. Now, as the twins sucked hungrily at her tits, their hands roamed over her body, exploring her. The hands squeezed her large breasts even as they were being sucked. Then they would travel over her stomach, always downward, to her thighs. With each twin's body pinning one of her legs to the bed, Xyla could not stop them from exploring her private places, their fingers moving to the tops of her thighs and then feeling and prodding her mound and slit through her panties.\n\nFor a few months, that was as far as it went. Then, one night, Xyla felt her daughter's hand pull the crotch of Xyla's panties aside, and her son's fingers began to feel the folds of her bare pussy.\n\n\"Stop!\" Xyla cried. \"Please, I'm your mother! You can't touch me that way!\"\n\nBoth children stopped nursing and looked up at her. In their eyes, she saw nothing but malice.\n\n\"You have to let us!\" Zeryn shouted. \"Don't you love us?\"\n\n\"Of course I do,\" Xyla said deliberately, afraid of what response any other answer might provoke. \"But mothers and children don't show their love that way.\"\n\n\"But that's how we WANT to love you, mother,\" said Yori, baring her teeth. \"Now let us.\"\n\nThe twins' hands gripped Xyla's body painfully hard. She couldn't say no, or surely they would hurt her. Perhaps badly.\n\nSo she cooperated, fighting back tears of shame as her children explored her exposed pussy. Their fingers inspected her fleshy labia, pinched her clitoris, sought out her opening. The finger that found it first worked its way inside; she couldn't even tell which child's it was.\n\nIf she thought the helpless sobs she broke into when that first finger penetrated her would stop them, she was wrong. Even as they fed, they forced a second finger into her cunt, hurting her. Then they finger-fucked her roughly until they had their fill of milk and went to bed.\n\n\"Good night, mother,\" said Yori as they left Xyla’s bedroom. \"We love you.\" There was no love in the words at all.\n\n---\n\nPart 4: Need\n\nThe next night, the twins got on the bed with Xyla as usual. This time, though, before the twins mounted her thighs, Yori said, “Take your panties off, mother. You don’t need to wear them to bed anymore.” Then, baring a bit of fang, she added, “They’ll just get damaged.”\n\nUnderstanding the implicit threat, Xyla closed her eyes in shame and lowered her panties to her knees. Zeryn yanked them the rest of the way off, and both twins took their usual positions, hungrily sucking and sucking as always.\n\nBut then, just as it seemed they were close to getting their nightly fill, something new happened. In one coordinated movement, Yori moved off of Xyla's left thigh and lay beside her as Zeryn dismounted her right thigh and moved his hips between her legs.\n\nShe could feel his hard penis against her inner thigh, and she knew immediately what he intended.\n\n\"No,\" she gasped, too frightened to do more than whisper. \"Don't. Don't rape me. Don't rape mommy.\"\n\n\"Mommy,\" Yori said, running her hand over Xyla's full breast, \"if Zeryn rapes you, it's only because he has to.\"\n\n\"You don't love us the way we need,\" Zeryn added, almost petulantly. \"So we have to make you.\"\n\nXyla struggled, but Yori pinned her arms, and her legs were useless, flailing helplessly on either side of Zeryn's hips. He pressed his pelvis down, grinding his cock against her thigh. It was about five inches long and steel-hard, and she could feel the knot at its base.\n\n\"Why would you do this to me?\" Xyla whimpered desperately as Zeryn positioned himself for entry. She turned her head and looked at Yori. \"And why would you help him?\"\n\n\"We've been doing this with each other for months, mother,\" Yori explained. \"Zeryn just wanted to know if it would feel any different with you. And I'm helping him because I love him--the way YOU should.\"\n\n\"Don't.\" Xyla was begging now as Zeryn put his cockhead between her cuntlips. \"Please don't.\"\n\nZeryn's only response was to thrust his cock into her. She screamed.\n\nZeryn made a few rough thrusts, Xyla howling for him to stop on each one, but he didn’t manage to penetrate more than an inch or so. He ignored Xyla’s cries and turned to his sister.\n\n\"She's too dry. I need some lube.\"\n\n\"That's easy enough,\" Yori answered. She roughly grabbed one of Xyla's breasts and squeezed hard, forcing a good quantity of milk out as Xyla yelped in pain. Yori caught the milk in her other hand, then reached down between her brother and mother's bodies and poured the milk over her brother's cock and the cunt it was invading.\n\n\"See if that helps,\" Yori said.\n\nZeryn gave another thrust, this time penetrating his mother considerably deeper, making her gasp in pain and horror.\n\n\"That's MUCH better,\" the boy said. \"Thanks, sis.\"\n\nYori responded by leaning over and giving her brother a sloppy, open-mouthed kiss. Xyla couldn't have been more disgusted. At least, not until her son began pumping his cock in and out of her, building a slow, strong rhythm.\n\n\"How does it feel?\" Yori asked with intense curiosity.\n\nNot interrupting his thrusts, the boy said, \"She's not... as tight...as you...but...it's good....I like...watching...her big titties...jiggle...when I...shove it in.\"\n\n\"I'll have big titties too, someday,\" Yori said, sounding slightly jealous.\n\n\"Even if...you don't...I'll never...stop fucking you...\" her brother gasped.\n\nMollified and aroused, Yori reached down and began to rub her clit.\n\nXyla was so mortified she couldn't bear it. Her son--all of four years old--was on top of her, inside her, raping her, and he and his sister were just...CHATTING, like she wasn't even there.\n\nThen Yori's mouth latched onto Xyla's breast and sucked it as hard as she ever had. Between Yori's forceful sucking and Zeryn's invading cock, Xyla was in agony.\n\nYori let up for a moment. \"Keep fucking her, Zeryn. I think she gives up more milk with your cock in her.\"\n\n\"Then I'll have to do this every night,\" Zeryn said cruelly. \"I'd hate for you to go hungry.\"\n\n\"PLEASE STOP THIS!\" Xyla screamed.\n\n\"Stop what, mommy?\" Yori said, painfully gripping Xyla's tit. \"Do you want Zeryn to stop fucking you? If you do, you'll have to be polite like you taught us. You'll have to say, 'Please stop fucking me, Zeryn.'\"\n\n\"P-p-please...please stop...\"\n\n\"Stop…what… mommy?\" Zeryn said, thrusting harder.\n\n\"Stop...f-f-f-fucking me, Zeryn,\" she begged.\n\n\"Hmm...no,\" said Zeryn, thrusting again.\n\n\"Hey, I didn't say he would agree,\" said Yori.\n\nXyla began bawling, but this only seemed to encourage Zeryn. He fucked his mother harder and faster, his sister encouraging him all the while.\n\n“Fuck her, Zeryn. Fuck the cunt we came out of. Make mommy love you like she should.”\n\nNever stopping his thrusts, Zeryn grabbed Xyla under her jaw and forced her to look at him.\n\n“Love me,” he snarled. “Love me with your cunt.”\n\nHe thrust harder still into his suffering mother’s body, never looking away from her pleading eyes as he forced his cock into her again and again. Yori grabbed both of Xyla’s tits and kneaded them cruelly, hard enough to bruise, making them leak copiously. Milk flowed down the tops of the prone woman’s breasts, reaching the base of her neck to mix with her tears.\n\n“That’s it, mommy,” Yori taunted. “Take it in your cunt. Take Zeryn’s cock deep inside you, like a loving mother would.”\n\nHearing Yori talk seemed to be turning Zeryn on—he started thrusting as hard as he could, his hipbones jabbing painfully into Xyla’s thighs with every stroke. Sitting up, Yori reached over and fondled Zeryn’s boyish but muscular ass with one hand while she masturbated herself with the other.\n\n“Now, Zeryn!” she gasped anxiously as she rubbed her clit faster and faster. “Give her your special gift. Give it to her now!”\n\n“Yeah!” cried Zeryn, and he shoved his cock as hard as he could into Xyla’s cunt. Xyla screamed as the boy’s knot stretched her entrance wider than anything had since her rape four years earlier. \n\nWith his cock buried as deep inside his mother as it could go, Zeryn spasmed with intense orgasm as he screamed “Take it take it TAKE IT!”\n\nYori cried out with her own orgasm, gripping Zeryn’s ass hard with her free hand, only heightening the boy’s own pleasure as he came and came.\n\nWhen it was over, Zeryn lay on top of Xyla, Yori stroking his hair while Xyla endured the humiliation of having to wait for Zeryn’s knot to go down before he could take his cock out of her. After about five minutes, he finally judged it safe to pull out. At that point, Xyla looked down at her son’s penis and her own abused vagina.\n\nNo semen, she thought. Oh thank God he’s at least not old enough for that.\n\n“That was amazing, Zeryn,” Yori said. “I hope you can get it up again soon; I need you to fuck me, too.”\n\n“You know I can,” Zeryn answered as they left their tearful mother in her bed.\n\n---\n\nPart 5: Desperation\n\nXyla, now alone in her dark bedroom, found herself unable to stop the flow of terrible thoughts through her head.\n\nI could leave them, she thought. I could just pack what I need and slip away in the middle of the night. They would never find me.\n\nBut the children would almost certainly go, or be taken, to the authorities, at which point Xyla would be wanted for child abandonment. Hiding her identity would become impossible if law enforcement were actually looking for her. And if the children were given a medical exam, which they probably would be, the DNA test would reveal their parentage. Xyla couldn’t stand the thought.\n\nThe truth was, there was no way out as long as she and the children were alive. Which led her to an even darker thought.\n\nShe could kill them. She was no match for them physically, of course, and trying to stab them to death in their sleep would be too risky, but she could poison their food.\n\nShe quickly put the thought out of her mind. There was no good way to get rid of a body, let alone two, in the City. Between the dense population and the many cameras that monitored every outdoor space, it was virtually impossible even to litter—never mind dump a corpse—without being noticed. \n\nAnd even if none of that were true, she knew she couldn’t do it: not to any child, regardless of their faults.\n\nThat left only one route of escape from her nightmare. But she couldn’t do that, either. Even if she could muster the nerve to kill herself, it would be wrong. Life was sacred, even hers.\n\n***\n\nThe next night was the same—the twins fed and felt her up, then Zeryn raped her while Yori held her down (even though Xyla didn’t struggle) and masturbated to the sight. Xyla was humiliated. Her children OWNED her now. Her body was just something for them to feed from and play with and penetrate whenever they wanted. And they wanted, every night.\n\nFeeding and fucking became their routine for the next week. As the week went on, though, the emphasis became less on feeding and more on fucking or otherwise playing—often painfully— with Xyla’s body. After a few nights of raping her missionary style, Zeryn switched to mounting her from behind while Yori pinched and tortured her tits from beneath. \n\nAt the end of the week, the twins just took a few pulls of her milk each before Zeryn fucked her and Yori began masturbating and playing with Xyla’s tits. That night, as Zeryn came, Yori grabbed Xyla’s breasts and gripped both of them so hard that milk squirted everywhere, soaking the bed, until Yori had squeezed out every last painful drop.\n\nThe next night, though, things went rather differently. After the twins got their few gratuitous sucks of milk, Yori turned over on all fours and waited.\n\n“Sorry, mommy,” Zeryn said, “but Yori called dibs on me tonight.” Then he climbed over Xyla and kneeled behind his sister.\n\nXyla didn’t know whether to be relieved or nauseated. At least she wasn’t being raped again, but the thought of Yori and Zeryn having sex in her bed, right in front of her, was vile. She knew they wouldn’t let her leave, so she turned her face away and closed her eyes.\n\n“No! You WATCH!” shouted Yori, grabbing Xyla under her muzzle and forcing her head to turn around. Yori was more than angry; she sounded almost tearful. “You watch us love each other!”\n\nSo Xyla watched, choking back her disgust, as Yori got back down on her elbows and Zeryn entered her from behind. \n\nAlmost instantly, the rage on Yori’s face melted away. She let out a hushed gasp, and then, faintly, smiled. Xyla couldn’t remember the list time she saw a smile on Yori’s face that wasn’t edged with cruelty. Looking up, she saw nearly the same look on Zeryn’s face—no malice, no vicious lust, just something that looked like…not quite happiness, or satisfaction, but something in that direction.\n\nZeryn moved slowly in and out of Yori, holding her hips not with the savage, bruising grip he used on Xyla, but just firmly enough to help his sister move in time with him, maximizing his penetration with each stroke. Each of them screwed their eyes shut as though they were concentrating solely on the feeling of fucking each other. With every stroke, they softly vocalized in unison, “Ah, ah, ah, ah….”\n\nThey seemed to be in no hurry to reach orgasm. They fucked, and fucked, and fucked, never tiring, never changing positions or their expressions of almost-bliss.\n\nFinally, after more than twenty minutes, Zeryn accelerated his pace, and soon he and Yori came, screaming. Then they fell on the bed, Zeryn on top of Yori and knotted inside her.\n\nYori turned to Xyla and said, “See how Zeryn loves me?”\n\nZeryn added, “Why can’t YOU love us, mother?”\n\nXyla was too shocked and disgusted to speak.\n\n***\n\nAnd then, the following afternoon, she went out to the store for a few things she couldn’t get online. When she came back to her apartment, the twins weren't there.\n\n\"Yori? Zeryn? Where are you?\" she called nervously, fearing that this was a prelude to some sort of cruel trick. There was no answer.\n\nShe went to their room. Their shared closet and some of their dresser drawers were open, and various articles of clothing were missing. Their bookbags were gone, too, although the books they once held now lay scattered on the floor--replaced, presumably, with clothing.\n\nIn the kitchen, a couple of cabinets were open. Most of the canned goods that had been stored there were gone. That made it clear that they hadn’t been kidnapped, or taken by Social Services.\n\nIt was obvious now: Wherever they had gone, they had done it of their own free will, with at least a week’s worth of food.\n\nDid she dare to believe it? That they had left, maybe for good?\n\nShe dropped to her knees among the discarded books. With closed eyes and clasped hands, she whispered, “Thank you, thank you, thank you,” over and over again.\n\n---\n\nPart 6: Surprise\n\nIt had been almost a year and a half since her children had disappeared, and when Xyla was honest with herself, she felt nothing but relief. No more moving from sector to sector of the City; no more hiding and living in fear; and no more sexual abuse and humiliation at the hands of her own children.\n\nShe still had to lie, of course--she couldn't tell anyone her real name or talk about her real past, especially the twins--but at least now they were the same lies, told to everyone consistently. Maybe, when she had told them long enough, they would start to feel like the truth.\n\nShe was done with her day's work--another eight hours of peaceful monotony, tracking records at a law firm--and she was coming home for a quiet evening of dinner and reading or television. She didn't have very many friends to socialize with, but that seemed necessary; a smaller social circle meant fewer chances to give herself away accidentally.\n\nXyla unlocked the door to her apartment, where she had moved a couple of weeks after Yori and Zeryn disappeared. It was small, but it was cheap and safe, and she was one of hundreds of anonymous residents who minded their own business and made no connections with one another.\n\nShe turned on the light in the main room as she locked the door behind her. She turned, and there they were on the sofa.\n\nThey had changed quite a lot. When she had last seen them, they were still children, but now they looked like young teens. Both were growth-spurt tall and slim, with more than a hint of wiry muscle, and Yori now had small, perky breasts. But Xyla couldn't mistake those faces--sleek muzzles, eyes like hers, and that expression that always hovered somewhere on a continuum between amusement and malice.\n\nHer eyes flicked toward the door.\n \n\"Don't run, mother,\" Zeryn said, lounging next to his sister on the couch. \"Where would you go?\"\n \n\"And who would you say you were running from?\" Yori added.\n \n\"Wha-What are you doing here?\"\n \n\"We just need a place to stay for a month or so,\" said Zeryn. \"So we thought we'd come see our dear mommy.\"\n \n\"You weren't that hard to find,\" Yori noted. “And I can’t say I’m that impressed with your complex’s security; your locks and cameras are good, but it took only a couple of fake IDs, a blowjob, and a veiled threat to get your building manager to give us a copy of your key.”\n\n“It’s nice that the walls are soundproofed for privacy, though,” Zeryn added, smiling slyly. “We wouldn’t want anyone interrupting the more fun parts of our-” he ran his hand over his crotch “-reunion.”\n\nYori got up from the couch, walked over to Xyla, and took her hand, gripping it firmly as she looked her mother in the eye.\n \n\"We've learned a lot about ourselves since we went to live among the Ferals,\" Yori said. Xyla's eyes widened in disbelief, but she said nothing.\n\n\"A LOT,\" Zeryn repeated.\n\n\"For example,\" Yori continued as she led her mother toward the couch, \"did you know that all Feral females are bisexual? It's how we bond\"--she squeezed Xyla's hand a little harder--\"and how we show dominance.”\n\n\"Speaking of which,\" Zeryn said, still in a relaxed pose on the couch, \"take off your clothes.\"\n\nXyla took a step back, shaking her head rapidly in reflexive panic.\n\n\"Mother,\" Yori said, moving so close that her young breasts pressed against Xyla's, \"I was as strong as you when I was four. How strong would you guess I am now?\"\n \nXyla swallowed, wide-eyed.\n\n\"Let's go to the bedroom,\" Zeryn said. \"I know it's not the same one, but maybe it will feel like old times, anyway.\"\n \nYori easily dragged Xyla back to the rear of the apartment and into her small bedroom. Then she held Xyla still.\n \n\"Now,\" Zeryn said, \"if you promise to act like a good, loving mother and do everything we want, then Yori will take your clothes off. But if you don't, she'll RIP them off, and they'll be ruined. What do you say?\"\n\n\"Please,\" she begged, using the only gambit she could think of. \"You're...you're both grown and beautiful now. You can have anyone you want. You don't have to rape your mommy.\"\n \n\"Oh,\" said Yori, \"I suppose that's true. We don't have to.\"\n \n\"We just want to,\" Zeryn finished.\n\n\"We didn't get nearly enough love from you as children,\" Yori explained. \"Feral females don't just bond sexually with each other; they do it with their offspring, too.\"\n \n\"That's disgusting,\" Xyla said, looking at the floor.\n \n\"No, mother, it's being alive. It's FEELING. Something most Civils aren't good at--especially you.\"\n\nZeryn took off his shirt and added, \"But don't worry; we're going to make you feel something right now.\"\n\nYori went over to Zeryn and unfastened his pants for him, letting them fall to the floor and taking hold of what was inside.\n\n\"Isn't it beautiful, mother?\" Yori asked, showing her Zeryn’s cock as if it were a precious objet d’art.\n\nXyla couldn’t believe it—Zeryn’s penis was literally twice the size it had been when she’d last been forced to see it. Now, it was more than ten inches long, bevel-pointed, and thick, with a tennis-ball-sized knot at the base. And he was going to put it…\n\nZeryn interrupted her horrible thought. \"Does it remind you of the ones our fathers had when they made us inside you?\"\n\nXyla gasped. She had never given the twins the slightest hint about how they had been conceived.\n\nYori must have seen the shock on Xyla's face. \"Oh, we've heard the story, mother. It was so...inspiring...that I had to ask some of the Feral males to fuck me right then and there.\"\n\n\"Speaking of fucking...\" Zeryn said impatiently.\n\n\"Oh, I'm sorry, Zeryn,\" said Yori. \"Let's get that nice big cock of yours into mommy's cunt. I'm sure it's missed you.\"\n\nXyla was too frightened to move, so Yori simply took the passive woman's clothes off, starting with her shirt and bra.\n\nYori paused to take a good look at her mother's breasts. \"I see you haven't lost much size since we stopped feeding from you, mother.\"\n\nXyla looked at the floor. \"I suppose you're proud of making me look like this,\" she heard herself say.\n\nStrangely, the accusation incited no anger at all. \"YOU should be proud, mother,\" Yori said. \"Feral females consider big breasts a badge of honor; they show that a female has given children to her band and that she can feed those children well.\"\n\nXyla tried to avoid showing her disdain for such a primitive notion. It didn't require a great deal of effort; Xyla was too consumed with fear over what was about to happen as Yori stripped her of her skirt and panties.\n\nOnce Xyla was naked, Zeryn said, \"Lie down on the bed, mother. I want it to be like our first time was.\"\n\n\"With one big difference,\" Yori added, momentarily fondling Zeryn's erect cock when she spoke the word \"big.\" Then Yori quickly shucked off her own top and skirt. She wore nothing underneath.\n\nHelpless, Xyla lay back and began weeping.\n\n\"Don't you DARE cry!\" Yori shouted. \"Zeryn's love is a gift. You should be grateful!\"\n\n\"Sis, let’s not get into that,\" Zeryn said in a tone that was half pleading, half warning.\n\n\"I'm sorry, brother,\" Yori said. Then she turned to her mother. \"Now open wide and take your cock like a good mommy.\"\n\nXyla, trying to stop the flow of her tears, began to spread her legs.\n\n\"Wider, mother,\" Zeryn ordered. \"And raise up your knees. I like to get in deep.\"\n\n\"Mmm...\" said Yori, massaging her crotch and, apparently, reminiscing.\n\nXyla obeyed. Zeryn smiled and picked up his pants from the floor. Tied to the belt was a small hide pouch that Zeryn reached into with two fingers to extract a greasy brown gel--the very same substance Xyla's Feral rapists had used to lubricate her years before.\n\n\"Rendered animal fat, with kelberry juice as a preservative,\" Zeryn explained. \"Every Feral male carries it; you never know when you'll need it.\"\n\n\"And Zeryn needs it quite a lot,\" Yori added proudly.\n\nZeryn knelt on the bed between Xyla's legs and smeared a fingerful of the grease inside his mother's cuntlips, making sure to get some of it inside her hole. Then, with a wolfish smile, he mounted her and positioned his cockhead against her entrance.\n\n\"Zeryn,\" Yori half-moaned, rubbing her pussy a little harder, \"I never get tired of watching you do that. Especially when it's our mommy.\"\n\n“And I love it when you watch, Yori. Now watch this.”\n\nZeryn began sinking his thick phallus into Xyla’s tight hole. Xyla was too afraid to scream or fight back; she just gripped the sheets as she moaned in pain, anguish, and humiliation.\n\n“Oh, fuck, yes,” Zeryn said. “She’s so much tighter now that I’ve got my adult cock.”\n\n“I love your cock, Zeryn,” Yori said with feeling. “Make her love it, too.”\n\nZeryn forced more and more of his thick member into Xyla as she writhed and whimpered in pain and shame.\n\n“Please…” she begged pointlessly, mindlessly.\n\n“Please what, mommy?” Zeryn replied. “Please give you more cock? Of course I will—there are still four inches left to go.”\n\n“Not including the knot,” Yori added. “Or did you mean, ‘Please squeeze my big tits like you used to’? Because I’d be happy to.”\n\nYori grabbed her mother’s breasts and began kneading them roughly, smiling like she was playing with some wonderful, long-lost toy.\n\nZeryn got his cock in all the way to the base of his knot, then started to fuck his mother’s cunt, slowly but forcefully. The beveled end of his thick penis pressed painfully against her cervix at the end of every slow stroke, as if Zeryn were trying to force his way into her womb. Xyla began crying again.\n\nYori grabbed Xyla’s nipples, squeezing them just hard enough to threaten harm. “Why are you crying NOW, mother?”\n\n“It hurts!” Xyla shouted.\n\n“It wouldn’t hurt if you’d accept Zeryn inside you instead of fighting him.”\n\n“I’m not fighting him!” Xyla cried through her tears. “I’m doing everything you want!”\n\nInexplicably, Yori flew into a rage. “NO YOU’RE NOT!” she screamed. \n\n“Yori,” said Zeryn, “seriously, cut it out.”\n\n“I’m sorry,” Yori said, clearly straining to calm herself. “I’m sorry. Keep fucking her, Zeryn.”\n\nZeryn grabbed Yori and gave her a big tongue kiss even as he continued to thrust into Xyla. Yori seized her brother’s shoulders and kissed him back, hard. There was something almost desperate in it.\n\nWhen they released each other, Yori said, “Thank you, Zeryn.”\n\n“Of course, sis.”\n\n“Now,” said Yori, “where were we?” Then she grabbed Xyla’s breasts and squeezed them as hard and painfully as before. Xyla cried out but was now too confused and frightened even to beg for mercy.\n\nZeryn began thrusting harder and faster, still hurting Xyla inside with every stroke. \n\n“That’s it, mommy,” he growled as he plunged into her again and again. “Take it all inside you. Take it nice and deep.”\n\n“That’s right, you fucking bitch,” Yori added, pulling harder on Xyla’s nipples. “You take Zeryn as deep as he wants. You let him inside your fucking womb, if that’s what he needs.”\n\nXyla began crying again. This only drove Yori to abuse her nipples more cruelly and Zeryn to fuck her harder.\n\nSoon, Zeryn gasped, “I’m gonna come…I’m gonna fill you up, mommy…”\n\nXyla’s eyes flew open in panic. “No! Don’t! I’m not on any birth control!”\n\n“Relax, mother,” Yori said, still twisting Xyla’s nipples painfully. “Ferals don’t have the same genetic issues that Civils do. Two close relatives can’t have a baby.”\n\nDeep down, Xyla knew it was a lie. But it was much, much easier to accept the lie than to face the possible truth.\n\n“YAAAAAAAAAH!” Zeryn screamed and thrust his knot into Xyla, making her shriek with agony. He pumped and pumped semen into her, thick and potent and painfully hot, just like that of the males who had first raped her.\n\n“Ah, fuck, yes,” Zeryn breathed as he collapsed on top of his mother, rooted inside her, still filling her with his come. Xyla sobbed beneath him.\n\n“Oh, cheer up, mother,” Yori said viciously. “You’ve got your babies back for a whole month.”\n\n“It’s so good to be home again, mother,” Zeryn said. “Just think of all the loving you’re going to get.”\n\nXyla only wept more loudly.\n\n---\n\nPart 7: Pain\n\nThat night, they didn’t remain in the bedroom; Xyla’s bed was too small for the three of them, so the twins insisted that Xyla spend her nights on the living room floor with them.\n\n“That way, we can spend more time together,” Yori explained with matter-of-fact cruelty. “Besides, Zeryn gets horny in the middle of the night, and I really need to catch up on my sleep.”\n\nThe twins also explained that Xyla would not be leaving the apartment for the next month. She would call in sick the next morning with an infectious disease, and she would work from home instead. It wouldn’t do to have her go into work, where people might see her and ask why she looked tired, or why she was walking funny.\n\nThe next three days were nightmarish. Not only did Zeryn always rape Xyla at least once during the day, but every night she would wake up to the pain of him penetrating her, raping her awake and then knotting her and filling her with come before he would let her go back to sleep.\n\nThe rest of their routine was bizarre, as well. The twins would wake up late, eat a huge breakfast, then lounge around for a bit, reading or watching television—mainly news. Then they would exercise, typically by wrestling with each other, which almost always ended in the siblings having loud, rough sex on the living room floor. Xyla, working at her desk in the bedroom, would stuff pieces of tissue into her ears to try to block out the sound.\n\nIn the evenings, well after dinner, the two would go out. They never told Xyla where, but given how they dressed and how late they would stay out, she guessed they were going to dance clubs or something similar. Then they would come home after Xyla had fallen asleep (in the living room, as they required) and pass out until late the next morning—except for Zeryn’s spontaneous rapes of Xyla in the wee hours when he was too horny to sleep.\n\nOn the fourth morning of their visit, the twins were in the kitchen, making their breakfast. Xyla was glad that at least they weren’t forcing her to cook for them. \n\nZeryn called, “Mother, come to the kitchen. And there’s no need to dress first; anything you wear will just get ruined.”\n\nAshamed, she obeyed. Both of her children were naked, and her son was clearly in a randy mood, feeling up her breasts and bottom the moment she stepped into the apartment’s kitchen area. The kitchen was separated from the living/dining room by a stainless-steel counter.\n\n“Are you going to rape me again?” Xyla asked, afraid but unable to stop herself from speaking. “Is this what it’s like among the Ferals? Violence and cruelty and rape? Yori, do the men just rape you whenever they want?”\n\n“Oh, mother, no worthy Feral male would HAVE to rape me.” Then, baring her fangs, she added, “And no unworthy male COULD.”\n\n“Besides,” said Zeryn, toying with Xyla’s breasts, “it’s nothing like the Feral Films they show on subscription television. There are occasional skirmishes between bands, but we basically live in peace.”\n\n“Rape is mostly for Civils,” Yori added. “Feral males aren’t particularly disposed toward violence against their own females, and Feral females aren’t nearly so repressed.”\n\n“But how do they treat YOU?” Xyla asked. “You’re half Civil; you must be freaks to them.”\n\nFor a moment, something like doubt flickered across Yori’s face. Then her familiar arrogance returned.\n\n“On the contrary, our Civil blood makes us...desirable, in certain ways.”\n\n“Yori here is very popular,” added Zeryn.\n\n“It’s true,” Yori replied. “I have males lining up to fuck me. Sometimes literally,” she added with a smile.\n\n“You’re a slut,” Xyla blurted, looking at the floor.\n\n“No, mother, I’m a woman.”\n\n“You’re not even six years old! And even you were as old as you look, you’d still be a child!”\n\nXyla clapped a hand over her own mouth. Why did she keep saying these stupid things that would only make the twins angry?\n\n“Why do Civils want to put everything off?” Yori asked. “Adulthood, responsibility, mating, childbirth, even death—you forestall every one of them for as long as you can.”\n\n“Maybe it’s their lifespan,” Zeryn mused even as he started tugging playfully on Xyla’s nipples.\n\nXyla tried to ignore Zeryn’s hands. “I’ve heard that Ferals rarely live past forty,” she said. “I suppose that makes them want to do everything as early as possible. If they would just embrace modern medicine, clean food and water…think how much better their lives would be.”\n\n“Mother, longer is not better,” said Zeryn. “Do you know what Ferals call their race? The Living. And they call Civils the Dead. In their eyes, your lives are sterile, empty, pointless. They would rather live to the fullest for a few decades then spend a hundred years living in little boxes stacked on top of one another, hiding from the world.”\n\n“Barely feeling,” Yori added, “barely mourning, barely loving.”\n\nZeryn slid his hand down to Xyla’s crotch. “Well, that seems like enough cultural conversation for one morning,” he said. Then he turned to Yori as he forced Xyla’s legs apart with his knee and started fingering his mother’s pussy. \"Sis, I was thinking: calling her 'Mother' and 'Mommy' just doesn't seem adequate anymore.\"\n\n\"Hmm...” Yori answered, seemingly happy that Zeryn had changed the subject. “Did you have something else in mind?\"\n\n\"How about 'Cuntmommy'?\"\n\nXyla's eyes widened in horror. The rape and molestation were bad enough, but somehow, this was too much.\n\n\"Oh, yes, that's much more descriptive,\" Yori said. She turned to her mother. \"Isn't Zeryn clever, Cuntmommy?\"\n\nBefore Xyla could even think, she heard herself screaming, \"Don't call me that!\"\n\nIn a flash, Xyla’s back was against the refrigerator and Yori's hand was on her throat.\n\n\"Look, Zeryn, Cuntmommy acts like she has a spine instead of just a cunt. Now we're going to have to punish her.\"\n\n\"Well, she DOES have more than just a cunt, Yori. She also has an asshole.\"\n\nXyla froze with terror.\n\n\"Oh, Zeryn,\" Yori said, \"you are just SO full of good ideas.\"\n\n\"Cuntmommy is about to be full, too.\"\n\nYori stepped back and allowed Zeryn to grab Xyla by the hair and drag her to the kitchen counter. He forcefully bent her over it, pushing her down until her big breasts were mashed against the cold stainless steel.\n\nEver helpful, Yori opened a few kitchen cabinets until she found some vegetable oil. \"Here, brother, let me take care of you. You’re already running out of the lube you brought, and I don't want you hurting that beautiful cock of yours while you're trying to shove it into our insolent Cuntmommy.\"\n\n\"Sis, you are the sweetest girl ever.\"\n\nYori poured a little oil into her hand and then obscenely spread it all over Zeryn’s erect wolf-cock, sliding her hand up and down its length a bit more than necessary, coating every last square millimeter and spending extra time caressing his thick knot.\n\nThen she moved her hand to her mother’s vulnerable rump. Xyla struggled helplessly as Yori’s oil-slicked finger entered her anus and pumped in and out a few times.\n\n“Tight,” Yori said, pulling her finger out and cuddling up to her brother. “You’re going to have fun in there. Mommy, not so much.”\n\n“Please!” Xyla screamed. “I’m sorry! You can call me Cuntmommy. You can call me anything you want!”\n\n“And we will,” Zeryn said. “Right after your punishment.” He put the pointed tip of his wolf-cock against her pink anus.\n\n“DON’T! Please, it will never fit!”\n\n“Don’t worry, Cuntmommy,” Zeryn said, “I’ll MAKE it fit.”\n\nHe began to force the head of his cock in, ignoring Xyla’s howl of agony. His nearly conical cockhead seemed the perfect tool for forcing open an unwilling asshole; Xyla’s pink ring gradually stretched wide as Zeryn slowly but forcefully pushed his cockhead through it.\n\nOnce he got the head all the way in, Zeryn gasped, “Oh, Cuntmommy, your asshole is so beautifully tight, I could fuck it all day. Maybe I will.”\n\nXyla began to cry. Yori, enraged, grabbed Xyla by the muzzle and forced her mother’s eyes to meet her own.\n\n“Always the fucking crying! You should be glad my brother wants to put his cock in you at all, you icy bitch!”\n\nWith the hard part out of the way, Zeryn was now sliding the rest of his ten inches into his mother’s anus. Xyla thought she had endured as much pain and shame as she ever would, but she was wrong; being sodomized in her kitchen, the cold steel countertop against her breasts as her own son’s cock traveled farther and farther into her bowels, was the most degrading thing that had ever happened to her.\n\nAll of which seemed to be turning Zeryn on to no end. The moment he got his whole cock (save for the knot) into her, he began fucking her ass hard and fast, thrusting deep into her bowels again and again as she screamed and cried and mindlessly begged him to stop. \n\nHe didn’t knot her when he came; he must have sensed that doing so would tear her open. Instead, he just gripped her ass tightly, his knot pressed against her violated anus, as he ejaculated what felt like a quart of thick, searing-hot semen into her gut.\n\nZeryn leaned over her, his front pressing against her back, his cock still buried in her ass. \n\n“Learn your lesson yet, Cuntmommy?” he said. “No backtalk.”\n\nXyla couldn’t even reply. Her throat was sore from crying and screaming.\n\nZeryn pulled out, and Xyla could feel his semen gushing from her anus onto the kitchen floor. One more humiliation.\n\n“I hope you liked that, you fucking bitch!” Yori said angrily. She pulled back her hand and slapped Xyla across the face, hard.\n\n“Yori, what’s the matter?” said Zeryn. There was genuine concern in his voice.\n\n“I want to hurt her too!” Yori cried, somehow upset.\n\nZeryn went around to the other side of the kitchen counter and put his arms around his sister. “Sweetie, you can hurt her all you want,” he said, clearly trying to reassure her.\n\nYori looked in his eyes. “I want to hurt her the way you do,” she said, voice quavering. “I just wish I could make her…FEEL me, like you can.”\n\nZeryn held her closer. “I know, baby, I know. It’s not fair.” Then he lifted his head. “I think I know what will cheer you up.”\n\nHe went over to where Xyla still lay over the kitchen counter, her face in a small pool of her own tears. Zeryn grabbed Xyla by the hair and jerked her head up.\n\n“Lie down on the counter,” he commanded.\n\nShe hesitated for the barest moment, then wiped her eyes and did as Zeryn said.\n\n“Now,” Zeryn said, “you’re going to eat your daughter’s pussy.”\n\nYori looked at him. “Oh, Zeryn, that’s so sweet.”\n\n\"It's the least I can do, sis, after all the times you held her down for me,\" Zeryn said as he helped Yori up onto the counter.\n\n\"Even so, I'm going to suck your cock after this.\"\n\n\"You'd do that anyway,\" Zeryn said.\n\n“I can’t help it,” said Yori. “A stomach full of your come just feels like love.”\n\n“That’s because it is,” Zeryn answered, reaching over to play with one of Yori's nipples the way she liked as the girl squatted over her mother’s face.\n\n“Now lick me, Cuntmommy,” Yori commanded, “or I’ll shove your muzzle up my pussy, and then you can forget about breathing until I come. If you last that long.”\n\nIt was a rough morning for Xyla.\n\n---\n\nPart 8: Hopelessness\n\nIt had been twenty-five days since the twins arrived. Twenty-five days of rape, forced cunnilingus, pain, and humiliation. The only thing that kept Xyla going was the fact that the twins were only planning to stay for a month. Soon it would be over.\n\nIt was mid-afternoon, and Xyla had just emerged from her bedroom office to get a glass of water from the kitchen. The twins weren’t in the living room as usual, but the bathroom door was closed. She could hear voices from behind it. That was odd—the twins never spent time in the bathroom except when they scrubbed each other’s backs in the shower (an act typically followed by loud shower-sex).\n\nShe crept over to the door. She was terrified of getting caught, but something inside her insisted on hearing what the two siblings were saying.\n\n“Sis, it’s never going to work,” she heard Zeryn say.\n\n“Can’t we at least TRY?” Yori replied, sounding upset. Not angry-upset. but sad-upset, which was unusual.\n\n“All right, but you have to promise not to get too emotional if it doesn’t work.”\n\n“I promise. I just need to know.”\n\n“Okay. Just remember that I love you.”\n\n“I love you, too, Zeryn.”\n\nSensing that their conversation was over, Xyla moved as quickly and quietly as possible toward the kitchen. She was already filling a water glass from the sink when the twins emerged from the bathroom.\n\n“Mother,” Yori said, not calling her “Cuntmommy” for the first time in three weeks, “come to the bedroom.”\n\nShe bolted her water and obeyed, bracing herself for yet another session of rape and abuse. When she got to the bedroom, she awaited Zeryn’s usual order to lie down and spread her legs, or to get on all fours on the bed.\n\nInstead, Zeryn kissed her. Not the way he usually did—forcing his tongue into her mouth, hands roaming everywhere—but softly, only barely applying pressure. Then he backed away, and Yori kissed Xyla the same way. She moved closer, her body up against Xyla’s, as Zeryn moved around and gently pressed his own body against Xyla’s from behind. His hand stroked her shoulder and arm as his other hand stroked Yori’s. He kissed her neck, nipping gently, as Yori’s hand moved up to Xyla’s breast and caressed it softly.\n\nIt was revolting.\n\nXyla broke off her kiss with Yori. “What are you doing?”\n\n“We’re- we’re trying to be nice,” Yori said.\n\n“We’re trying to… make love to you…like Civils do,” Zeryn explained.\n\nXyla thought she might throw up.\n\n\"Why?\" Xyla said, starting to sob. \"Why can't you just leave me alone?\"\n \n\"Because we love you, mother,\" said Yori, almost pleading.\n \n\"No you DON'T!\" Xyla screamed. \"You're MONSTERS!\"\n \nFor the first time since Yori was a tiny child, Xyla actually saw tears come into her daughter's eyes.\n\n\"You- you don't understand,\" Yori said, clearly trying to keep from crying. \"You NEVER understood. We wouldn't be...monsters...if you'd loved us right.\"\n\n\"Please, sis,\" said Zeryn, sounding a little choked up, \"you said you weren't going to do this.\"\n\n\"I can't help it,\" Yori quavered. \"I can't just keep holding it in! And neither can you. We have to explain.\"\n\nZeryn turned to Xyla. She could see tears welling in his eyes, too.\n\n\"We needed something, back then,\" he said. \"And we couldn't tell you what it was, because we didn't KNOW.\"\n\n\"We needed your love,\" Yori said. \"Not cold, sterile, Civil love--we needed the kind of deep, limitless, sexual love that Feral mothers give their children. And when you wouldn't give it to us, we had to take it. We didn't know another way.\"\n \nXyla shook her head in denial. \"No, no. It was never about love…You were greedy, and- and cruel. I could never give you anything without you wanting to take more, to twist it into something sick.\"\n \nA tear escaped Yori's eye. \"It's- it's because you were weak, mother. Weakness sets off something in Ferals, something…primal. We can FEEL weakness, and we can't help but hate it. Ferals have to control the weak, dominate them, hurt them.\"\n\n“It was especially hard for Yori,” Zeryn said. “To live day in and day out with a female who is as weak as you are…you have no idea how much she had to hold herself back, to keep from hurting you more than she did.”\n\n\"We needed you to be strong,\" Yori said through her tears. \"We just didn't know that.\"\n\nXyla was horrified--partly because, in a sense, Yori and Zeryn were right to be upset. She had brought them into the world because she was too afraid of the alternative, but she was also too afraid to think about what bearing two half-Feral children would really mean, or to ask anyone for help. She had hoped she could raise them as normal, Civil children, but she hadn't had the first clue what they would be like, or what they would need.\n \nShe sank to her knees. \"I'm sorry. I didn't...I...\"\n \nYori grabbed Xyla by her upper arms and yanked her to her feet.\n \n\"NO!\" Yori half-shouted, half-sobbed. \"I don't WANT you to be sorry! I want you to be STRONG! I want you to LOVE ME! I want...\" Her sadness and fury choked her off.\n\n\"It's no good, sis,\" said Zeryn, wiping his eyes. \"She'll never be our mother...not the one we needed. She's too weak, and too cold, even now.\"\n\nYori looked down, trying to rub the tears from her eyes and cheeks. When she looked up again, right at Xyla, her red-rimmed eyes were filled with rage.\n\n“Then RAPE HER! Rape her harder than you ever have! Make her hurt deep inside the way WE DO!”\n\nYori pulled back her fist to punch Xyla in the face. Xyla started to cringe, to try to avoid the blow, but Zeryn grabbed Yori’s fist and forced her fingers open.\n\n“We can’t hurt her too much, remember?” he said urgently.\n\nYori slapped Xyla’s face, then again, and again, as hard as she could, screaming her fury. Then she forced her mother down onto the bed on her back. Yori tore off her own underwear and grabbed Xyla’s muzzle, holding it closed.\n\n“You fucking bitch,” Yori sobbed. “You fucking, fucking bitch!”\n\nYori mounted Xyla’s face and, as she had threatened to do weeks before, forced her cunt down onto Xyla’s muzzle, shoving it inside. Xyla found herself staring at Yori’s clitoris and completely unable to breathe.\n\n“Yori, be careful!” Zeryn warned.\n\n“Just for a minute,” Yori begged. “Please, let me do this just for a minute. I NEED to!”\n\n“I know, baby, I know,” Zeryn said, dropping his pants. “Look, I’m going to rape her, okay? Just like you want.”\n\nYori lifted herself up, then savagely thrust her hips downward, burying her mother’s muzzle as deep in her cunt as it could go. Then Yori did it again, and again, and again as her mother flailed beneath her. \n\nZeryn thrust his cock into Xyla’s cunt and began fucking her hard, battering her cervix more brutally than ever before. Even as he shoved his cock into Xyla’s flailing body, he shouted, “Yori, get off her!”\n\n“Please, just a little longer…” Yori begged, still fucking her mother’s face with her cunt.\n\n“Get off her NOW! You’ll kill her!”\n\nChoking back tears, Yori lifted herself up and freed Xyla’s muzzle. Her mother gasped desperately for air.\n\nYori climbed off Xyla and then went over to Zeryn, grabbing his ass and pushing it forward rhythmically, helping him fuck, shoving him into Xyla with every raping stroke.\n\n“You make sure she’s good and pregnant,” Yori sobbed. “You knock her up just like all those other Civil cunts you fucked since we came here. You MAKE her have your baby! MAKE HER!”\n\nZeryn raped Xyla hard, grunting with every thrust as he forced his cock as deep into her as it could possibly go. Even he was starting to be overcome with rage.\n\n“Take it you fucking cunt! I’m gonna fill you with so much come your baby’s going to be born pregnant! YOU TAKE MY FUCKING COCK!”\n\nZeryn came and thrust his knot as hard as he could into Xyla, making her scream. Yori smiled tearfully, like it was the most beautiful sound she had ever heard. Then she kissed Zeryn hard, plunging her tongue into his mouth, suddenly desperate for him. Zeryn kissed her back just as hard, his hands grabbing her ass, his fingers probing her cunt and asshole the way she enjoyed. \n\nDespite the pain and shame of being knotted and of yet another enormous load of Zeryn’s burning-hot semen flooding her womb, Xyla was watching Yori’s face. She could see that Zeryn’s touch wasn’t just pleasing the girl; it seemed to be comforting her, too.\n\nYori grabbed Xyla’s tits and squeezed them painfully hard. “That’s right, you look at us! You look at what real love is—something you’ll NEVER feel, you numb cunt!”\n\nAfter a few minutes, Zeryn’s knot went down, and he pulled his cock out of Xyla. As usual, thick semen flowed like a river from her cunt. Yori fell on the bed and began eating it straight out of Xyla’s cunt, swallowing gob after gob of it like it was beyond delicious—like it was precious. Then, after consuming nearly a pint of her brother’s come, she thrust two fingers deep into Xyla’s pussy and scooped out an extra-large helping.\n\n“Open your mouth,” she said to Xyla, her voice ice cold.\n\nSeeing Yori’s unprecedented fury, Xyla was too afraid to disobey. The moment her lips parted, Yori shoved her fingers into Xyla’s mouth and deposited the gob of semen in the back of her mother’s throat.\n\n“That’s what my beautiful brother tastes like, you fucking bitch,” she said, still teary with rage and sadness. “That’s the closest you’ll ever get to tasting what love is. Now you fucking swallow it.”\n\nXyla did as she was told, trying not to cry—or vomit—and make Yori even more angry.\n\n“It’s time we left, sis,” said Zeryn. “We’ve done what we came to do, and you’ve suffered enough, being here.”\n\nYori stood up. “You’re right, brother. It’s time to go back.”\n\nEven after all the torment, even as relief cascaded over Xyla at the thought of the twins finally leaving her alone, she couldn’t stop herself from speaking.\n\n“You said, ‘go back,’” she observed tearfully. “Not ‘go home.’”\n\nZeryn cast his eyes downward. “We don’t…exactly…fit in, out there. Even with the band that fathered us. We’re too different.”\n\n“And we don’t have a mother,” Yori added. “Fathers don’t matter very much among the Ferals; most don’t even know which male of their band sired them. It’s your mother that gives you status, and as far as they’re concerned, we don’t have one.”\n\n“Then why do you stay with them?” Xyla asked.\n\n“They may not fully accept us, but they’re good to us…because they need us,” Zeryn explained. “We’re part of their plan.”\n\n“Great God,” Xyla said. “Are they planning some kind of invasion?”\n\n“No, mother,” Yori said. “As amusing as Civils might find it to watch on the evening news, the Ferals are not planning to charge the gates with their spears to be mowed down by a handful of Civils with autorifles.”\n\n“But they DO hate Civil weakness,” Zeryn said. “So they’re attacking it with the most powerful weapon they have—their blood.”\n\n“Ferals and Civils don’t interbreed very easily,” Yori explained. “It was great luck that our fathers managed to impregnate you, and a handful of other Civil females. The next generation, the ones fathered by Zeryn and the other half-Civil males the Ferals have managed to sneak into the City over the years—mostly with help from Civil sympathizers—that generation will be only a quarter Feral.”\n\n“They’ll fit in better,” Zeryn added. “They won’t grow as fast, won’t have the same…issues we had. But they’ll still have the spark of life, real life, inside them. And they will spread that spark throughout the City until it burns to the ground.”\n\n“And when they emerge from the ashes, the quarter-Civils born outside the walls will be there to greet them—and breed with them,” said Yori, putting a hand on her stomach. Looking closely, Xyla could see the barest curve of pregnancy. Her eyes flicked to Zeryn.\n\nYori seemed to notice this. “No, mother, they’re not his. Probably not, anyway; I’ve mated with every male in our band many, many times. I’m part of the plan, too, you see.”\n\n“The point is, mother,” Zeryn concluded, “the Ferals are going to eliminate Civil weakness forever. And in the end, Civils and Ferals will be one people again.”\n\nXyla had no idea what to say. Together, the traumas of the day and this new information were too much to process.\n\n“Goodbye, mother,” said Yori. “We won’t be back. I just can’t be around you anymore.”\n\nThey didn’t pack any of the clothes or other possessions they had brought. Xyla supposed they were just Civil camouflage, anyway; the twins wouldn’t need them outside the walls of the City. The twins simply took each other’s hands, and went.\n\nShe was alone now. Blessedly alone.\n\nBut not forever. Xyla had no doubt that she was pregnant again, and this time, her pregnancy was not just the product of rape, but of incest, as well.\n\nBut that wasn't the baby’s fault.\n\n- - -\n\nA big “thank you” to everyone who commented on, favorited, or otherwise expressed interest in this story.

Part 1: Impregnation

She had been told not to leave the group for any reason. Outside the city walls, one had no idea where Ferals might be lurking, and no one went out there without an armed escort. The two professors and twenty or so biology students on this scientific excursion had been accompanied by five guards with autorifles, and some of her fellow students who were qualified had personal weapons, too.

Xyla did not; guns scared her. What was more, anyone who had a firearm was expected to shoot Ferals on sight, and she didn't think she could kill a living thing, even if it was something as frightening and monstrous as a Feral. It was hard to believe that they were related to Civils; no wonder the Civils had walled themselves off from their fellow lupinoids more than a millennium ago.

Being new to the biology program, Xyla had no friends in the group. There were several familiar faces from class, but no one she had actually talked to much. She had never had much in the way of social skills. Thus, while the others clustered around various plants and flowers of interest, Xyla backed away to the edge of the clearing, casting around for some sort of flora that she could study by herself.

The hands that grabbed her from behind took her completely by surprise. They pulled her into the thick foliage around the clearing, and before she could scream, one of them shoved some sort of rough rag into her mouth. Another pair of hands tied a second rag tightly around her muzzle to keep it closed on the first rag. Then, quickly, two male forms picked her up and carried her away from the clearing, through the dense trees.

Thrashing around in a vain effort to escape, Xyla couldn't clearly see her assailants. But they had to be Ferals.

They arrived at another clearing several hundred yards away, where three more Ferals were waiting. They, too, were males, and naked. Each was holding one or two pieces of rope.

None of them said a word as they tied her spread-eagle on a tree stump that was nearly as large in diameter as she was tall. Each of her limbs was lashed to one of four saplings growing around the stump. Then, making no noise beyond a low grunt, the Ferals tore her clothing from her like it was paper.

The first of them approached her, holding his huge erection in his hand. Xyla wasn't very sexually experienced--in fact, she had only ever had sex once, with a short-term boyfriend, and she had not enjoyed it--but she knew most Civil men's penises were not nearly that big. It was nearly a foot long, and three inches wide. The knot at the base was wider still.

The Feral saw the way she was looking at his cock, and he stroked it gently, like it was a beloved pet. Then, with his free hand, he fondled her bare pussy as she squirmed helplessly. He was smearing something greasy inside her lips.

"Cunt," he growled with anticipation as he opened her wider with his hand.

"Nnnnnnnn!" Xyla screamed into her gag as the Feral placed the head of his monstrous member between her cunt folds. Ignoring her protests, he mounted her and began to push his massive wolf-penis into her. She screamed into the gag, harder than she had ever screamed in her life, as inch after inch after inch of cock was forced into her body, into her cunt, practically into her womb.

He didn't bother with preliminaries. Teeth bared, he fucked her hard and deep, every single shove battering her cervix as she screamed and screamed into her gag. The pain was unbelievable, worse than losing her virginity had been. She would have done anything to make him stop, but she was helpless even to speak, let alone move.

Even when he came it hurt, burning her insides like he'd poured molten plastic into her. She could actually feel it in her vulva, in her womb.

There was one small mercy—he did not knot her, which she believed would have torn her apart. Rather, he got off of her quickly, and another took his place. In the brief moment between mountings, she could see that the other Ferals were slowly masturbating, as if warming up for their turn. Now she knew she was in for a lot more rape, and she began crying.

They took her, one after another, until they had all had a turn, and then they started again. She alternately screamed, cried, and mindlessly begged through her gag as cock after cock violated her roughly and deeply, again and again, each time pouring another searing load of cum into her unprotected womb.

After nearly an hour, the Ferals were all spent. They untied her and, as they departed, one of them looked at her and pointed in the direction (she thought) of the clearing from which they had taken her. Then they vanished into the trees.

***

She returned to the clearing, staggering and clad in the shreds of her clothes. She made some excuse about falling down a hill covered in brambles, but it was clear that everyone knew what had happened to her. The entire group immediately packed up and returned to the City.

Xyla couldn't bear the shame--not just of what happened, but of everyone knowing, or at least suspecting. She refused medical treatment and went straight home, where she showered and showered and took massive doses of analgesic for the pain. As soon as she was numb enough to move around without agony, she began to pack her belongings. Fortunately, she didn't have terribly many.

It was a near certainty that someone on the field trip had reported the incident, so it wouldn't be long before she got a visit from the authorities. The very last thing she wanted was to tell anyone about what had happened, or to be poked and probed by doctors. And if she was pregnant, the consequences would be even worse. "Feral-induced pregnancies"--perhaps the euphemism of the century--were extremely rare, but by law, they had to be terminated. Xyla could never do that; what had happened to her was horrible, but even if they had put a baby in her, that wasn't the baby's fault.

So she moved out that very night, stayed in a motel on the other side of the City, and sought a new home in the morning. For all her lack of interpersonal skills, Xyla knew what she was doing online; she quickly set up a new identity for herself, far away from any part of the City where anyone might know her.

---

Part 2: Hunger

Before long, it became clear that Xyla was indeed pregnant. But this was not a normal pregnancy; by the time she was certain that her periods had stopped, about a month and a half after the rape, she was already starting to show.

She was afraid to seek any prenatal care, and she was afraid not to. So she just went a few times, finding a different doctor each time and promptly erasing any record of her visits. Three months into her pregnancy--when she looked to be about seven months along--she learned that she was to have twins, a boy and a girl.

One other abnormal aspect of her pregnancy was the substantial growth of her breasts. She had expected some of that, of course, but not to go from a small B cup to a full C in the space of two months. She didn't like it; she had never wanted to stand out in that way.

Just over four months after her forcible impregnation, she delivered the twins at a private hospital, where she paid for her care in cash with some of the money her late father--a distant man in life but generous in death--had left her. Not being close to her family, she simply chose names she had always liked the sound of: Yori for the girl, and Zeryn for the boy.

The first exceptional thing she noticed about the twins was their hunger. The babies usually took nearly twice the normal amount of time to feed, sucking hard--often painfully hard--the entire time. Seemingly in response to this demand, her breasts grew more, expanding to what Xyla considered an obscene size. She hated the way people, especially men, looked at her and her D-cup breasts when she had to leave the house to do some errand. Fortunately, that was rarely necessary; she could do her online job from home, and she had groceries and other supplies delivered.

The next thing she noticed was that the twins' development was just as rapid now as it had been in utero. By five months, they were walking like the one-year-olds they appeared to be. They learned to talk at eleven months, by which time they appeared to be at least two years old. Xyla was forced to move apartments twice just to keep people from noticing.

And still they breast-fed with unnatural, even ferocious hunger. Attempts to switch them to bottle-feeding were futile; they would scream and cry nonstop--once for an hour straight--until they got the breast milk they craved, directly from the source. Only gradually was she able to get them to eat SOME solid food, and even so, they still screamed if they did not get at least one breastfeeding a day.

Not only did the twins refuse to be completely weaned, but they had very strong preferences about the feeding process itself. By the time they were two (and looked at least four), they had an established ritual: They always did it in Xyla's bedroom, with Xyla lying on her back in bed, wearing panties and an open robe, and each child straddling one of her thighs as he or she sucked powerfully on Xyla's nipples.

One night, while the twins were feeding, Xyla felt a hardness moving against her thigh. She looked down and saw Zeryn very slowly hunching his hips against her naked skin. The sight and feel of it disgusted her, but she said nothing.

The next night, however, when dinner was nearly over, she addressed the twins at the kitchen table.

"You have both gotten old enough that it's not appropriate for you to breastfeed anymore. From now on, no more feedings at bedtime. Your dinner should be enough."

The twins looked shocked. "But mommy," Yori protested, "we get so hungry at night!"

"If you really need something," Xyla said, "you can get a snack from the refrigerator."

"But we NEED your milk, mommy!" Zeryn cried. "Nothing else is the same!"

Before Xyla could even reply, both twins stormed out of the kitchen and into their room, slamming the door behind them.

It's fine, Xyla told herself. They just need a little time to calm down and adjust to the idea.

They didn't emerge from their room until their bedtime, so Xyla opened their bedroom door and said, "Time for bed now." Strangely, though, the twins were already in bed, each of them looking at a book. Neither said anything to Xyla.

"Good night," she said as she closed their door. There was no reply.

Xyla went to her room and, just to be sure, locked the door.

For the first time in a long time, Xyla put on a nightgown. Wearing it felt like a relief.

About twenty minutes later, just after Xyla had turned out the light and closed her eyes, she heard someone trying the door handle--once, then again, then harder, shaking the door.

"Let us IN!" she heard Zeryn shout.

"We're HUNGRY!" Yori cried.

"No!" Xyla shouted nervously. "We're not doing that anymore! Go back to bed!"

But the twins would not be deterred. They banged on the door nonstop for a full minute, then two, then five.

"Stop it!" she shouted through the door, but the banging continued without pause.

Finally, she flung the door open, ready to scream at the children to stop. Their bodies slammed into the door; the edge of it clipped her head and knocked her down.

Before she could get up, the twins were on her. Between the two of them, they were strong enough to rip her nightgown down the middle, forcibly exposing her breasts. They leaped onto her thighs, pinning her down, and began sucking hard, harder than ever before, biting, bruising, hurting her, punishing her.

She tried pushing them off, even hitting them on their backs, but they were ferocious in their determination to feed. Nothing would stop them.

Finally, when they had had their fill, they left their sobbing mother on the floor and returned to their room.

---

Part 3: Want

Breastfeeding resumed as usual the next night. Xyla knew she had failed as a mother; if she had weaned them a year ago, none of this would have happened. Now, it was just easier to give them what they wanted. Surely, they would grow out of it eventually. Every child did, didn't they?

After that, every night when she lay down in bed and opened her robe for them, she would feel Zeryn's erection grow as he nursed on her, and he frequently would work it slowly against her thigh as he sucked at her tit. And soon, Yori began to do the same, rubbing her crotch against Xyla's other thigh while she nursed, leaving it damp afterward. The whole thing disgusted Xyla, but there was nothing she could do. She had lost control of the situation.

This went on for several months. As before, the children continued to grow at more than double the normal rate, and Xyla was forced to move to yet another new apartment in distant part of the City and enroll her children in school. She really didn't want to, but the law required that children over six years old attend, and no doubt someone would report the twins as truant if they were seen in the apartment or outside during the school day.

That went fine for a little while. Despite their chronological age, the children had no trouble keeping up with schoolwork. Social life was another matter, however. The twins tended to keep to themselves and would react strongly--sometimes violently--if one of their peers teased them for it. Xyla expected to have this problem with Zeryn, but it was just as bad with Yori, if not worse. She was mainly hostile toward other girls, especially any who tried to tell her what to do. Early in the year, Yori received a two-day suspension for beating up a girl who had accused her of cutting in line for the water fountain.

One day, about four months into the school year, the principal called her in, not saying what it was about until Xyla was seated in her office. She asked whether the children had problems at home, and whether Xyla had anyone else living with her besides the twins. Xyla said no.

"It seems," said the principal, "that Zeryn and Yori followed one of their classmates, a girl, into the washroom, and they...well, they made her take off her clothes, and they...abused her. Fondled her, I mean."

"A-are you sure?"

"The girl's description of the...incident...was very specific. She said, among other things, that Yori held her against the wall while Zeryn touched her."

Xyla was speechless. She wished she couldn't believe it, but there was nothing she could believe more easily.

"The girl’s parents," the principal continued, "have promised to refrain from legal action--against you AND the school--if you withdraw your children immediately."

And that was that. Xyla moved them again, established new identities, and started over once more.

***

They were getting bigger, and stronger. Now, at night, she felt the wiry strength in their hands when they held her--by the arm, the wrist, even the throat--as they suckled fiercely at her breasts. Even though she made no attempt to stop them or escape, they seemed to instinctively want to pin her down, to control her.

She was frightened of them. And she didn't know what was worse--the fear, or the shame she felt at being afraid of her own children.

Then, just when she thought it couldn't get any worse, it did.

Her children were four years old now, but they looked and acted as if they were nine. They were enrolled in school again and were keeping up with their studies somehow, even though they had missed half the education a normal, Civil child would have had by their apparent age. And, thankfully, they seemed to be keeping their hands to themselves--at school, anyway.

At home, however, the nightly breastfeeding hadn't stopped; it had only grown more degrading. Now, as the twins sucked hungrily at her tits, their hands roamed over her body, exploring her. The hands squeezed her large breasts even as they were being sucked. Then they would travel over her stomach, always downward, to her thighs. With each twin's body pinning one of her legs to the bed, Xyla could not stop them from exploring her private places, their fingers moving to the tops of her thighs and then feeling and prodding her mound and slit through her panties.

For a few months, that was as far as it went. Then, one night, Xyla felt her daughter's hand pull the crotch of Xyla's panties aside, and her son's fingers began to feel the folds of her bare pussy.

"Stop!" Xyla cried. "Please, I'm your mother! You can't touch me that way!"

Both children stopped nursing and looked up at her. In their eyes, she saw nothing but malice.

"You have to let us!" Zeryn shouted. "Don't you love us?"

"Of course I do," Xyla said deliberately, afraid of what response any other answer might provoke. "But mothers and children don't show their love that way."

"But that's how we WANT to love you, mother," said Yori, baring her teeth. "Now let us."

The twins' hands gripped Xyla's body painfully hard. She couldn't say no, or surely they would hurt her. Perhaps badly.

So she cooperated, fighting back tears of shame as her children explored her exposed pussy. Their fingers inspected her fleshy labia, pinched her clitoris, sought out her opening. The finger that found it first worked its way inside; she couldn't even tell which child's it was.

If she thought the helpless sobs she broke into when that first finger penetrated her would stop them, she was wrong. Even as they fed, they forced a second finger into her cunt, hurting her. Then they finger-fucked her roughly until they had their fill of milk and went to bed.

"Good night, mother," said Yori as they left Xyla’s bedroom. "We love you." There was no love in the words at all.

---

Part 4: Need

The next night, the twins got on the bed with Xyla as usual. This time, though, before the twins mounted her thighs, Yori said, “Take your panties off, mother. You don’t need to wear them to bed anymore.” Then, baring a bit of fang, she added, “They’ll just get damaged.”

Understanding the implicit threat, Xyla closed her eyes in shame and lowered her panties to her knees. Zeryn yanked them the rest of the way off, and both twins took their usual positions, hungrily sucking and sucking as always.

But then, just as it seemed they were close to getting their nightly fill, something new happened. In one coordinated movement, Yori moved off of Xyla's left thigh and lay beside her as Zeryn dismounted her right thigh and moved his hips between her legs.

She could feel his hard penis against her inner thigh, and she knew immediately what he intended.

"No," she gasped, too frightened to do more than whisper. "Don't. Don't rape me. Don't rape mommy."

"Mommy," Yori said, running her hand over Xyla's full breast, "if Zeryn rapes you, it's only because he has to."

"You don't love us the way we need," Zeryn added, almost petulantly. "So we have to make you."

Xyla struggled, but Yori pinned her arms, and her legs were useless, flailing helplessly on either side of Zeryn's hips. He pressed his pelvis down, grinding his cock against her thigh. It was about five inches long and steel-hard, and she could feel the knot at its base.

"Why would you do this to me?" Xyla whimpered desperately as Zeryn positioned himself for entry. She turned her head and looked at Yori. "And why would you help him?"

"We've been doing this with each other for months, mother," Yori explained. "Zeryn just wanted to know if it would feel any different with you. And I'm helping him because I love him--the way YOU should."

"Don't." Xyla was begging now as Zeryn put his cockhead between her cuntlips. "Please don't."

Zeryn's only response was to thrust his cock into her. She screamed.

Zeryn made a few rough thrusts, Xyla howling for him to stop on each one, but he didn’t manage to penetrate more than an inch or so. He ignored Xyla’s cries and turned to his sister.

"She's too dry. I need some lube."

"That's easy enough," Yori answered. She roughly grabbed one of Xyla's breasts and squeezed hard, forcing a good quantity of milk out as Xyla yelped in pain. Yori caught the milk in her other hand, then reached down between her brother and mother's bodies and poured the milk over her brother's cock and the cunt it was invading.

"See if that helps," Yori said.

Zeryn gave another thrust, this time penetrating his mother considerably deeper, making her gasp in pain and horror.

"That's MUCH better," the boy said. "Thanks, sis."

Yori responded by leaning over and giving her brother a sloppy, open-mouthed kiss. Xyla couldn't have been more disgusted. At least, not until her son began pumping his cock in and out of her, building a slow, strong rhythm.

"How does it feel?" Yori asked with intense curiosity.

Not interrupting his thrusts, the boy said, "She's not... as tight...as you...but...it's good....I like...watching...her big titties...jiggle...when I...shove it in."

"I'll have big titties too, someday," Yori said, sounding slightly jealous.

"Even if...you don't...I'll never...stop fucking you..." her brother gasped.

Mollified and aroused, Yori reached down and began to rub her clit.

Xyla was so mortified she couldn't bear it. Her son--all of four years old--was on top of her, inside her, raping her, and he and his sister were just...CHATTING, like she wasn't even there.

Then Yori's mouth latched onto Xyla's breast and sucked it as hard as she ever had. Between Yori's forceful sucking and Zeryn's invading cock, Xyla was in agony.

Yori let up for a moment. "Keep fucking her, Zeryn. I think she gives up more milk with your cock in her."

"Then I'll have to do this every night," Zeryn said cruelly. "I'd hate for you to go hungry."

"PLEASE STOP THIS!" Xyla screamed.

"Stop what, mommy?" Yori said, painfully gripping Xyla's tit. "Do you want Zeryn to stop fucking you? If you do, you'll have to be polite like you taught us. You'll have to say, 'Please stop fucking me, Zeryn.'"

"P-p-please...please stop..."

"Stop…what… mommy?" Zeryn said, thrusting harder.

"Stop...f-f-f-fucking me, Zeryn," she begged.

"Hmm...no," said Zeryn, thrusting again.

"Hey, I didn't say he would agree," said Yori.

Xyla began bawling, but this only seemed to encourage Zeryn. He fucked his mother harder and faster, his sister encouraging him all the while.

“Fuck her, Zeryn. Fuck the cunt we came out of. Make mommy love you like she should.”

Never stopping his thrusts, Zeryn grabbed Xyla under her jaw and forced her to look at him.

“Love me,” he snarled. “Love me with your cunt.”

He thrust harder still into his suffering mother’s body, never looking away from her pleading eyes as he forced his cock into her again and again. Yori grabbed both of Xyla’s tits and kneaded them cruelly, hard enough to bruise, making them leak copiously. Milk flowed down the tops of the prone woman’s breasts, reaching the base of her neck to mix with her tears.

“That’s it, mommy,” Yori taunted. “Take it in your cunt. Take Zeryn’s cock deep inside you, like a loving mother would.”

Hearing Yori talk seemed to be turning Zeryn on—he started thrusting as hard as he could, his hipbones jabbing painfully into Xyla’s thighs with every stroke. Sitting up, Yori reached over and fondled Zeryn’s boyish but muscular ass with one hand while she masturbated herself with the other.

“Now, Zeryn!” she gasped anxiously as she rubbed her clit faster and faster. “Give her your special gift. Give it to her now!”

“Yeah!” cried Zeryn, and he shoved his cock as hard as he could into Xyla’s cunt. Xyla screamed as the boy’s knot stretched her entrance wider than anything had since her rape four years earlier.

With his cock buried as deep inside his mother as it could go, Zeryn spasmed with intense orgasm as he screamed “Take it take it TAKE IT!”

Yori cried out with her own orgasm, gripping Zeryn’s ass hard with her free hand, only heightening the boy’s own pleasure as he came and came.

When it was over, Zeryn lay on top of Xyla, Yori stroking his hair while Xyla endured the humiliation of having to wait for Zeryn’s knot to go down before he could take his cock out of her. After about five minutes, he finally judged it safe to pull out. At that point, Xyla looked down at her son’s penis and her own abused vagina.

No semen, she thought. Oh thank God he’s at least not old enough for that.

“That was amazing, Zeryn,” Yori said. “I hope you can get it up again soon; I need you to fuck me, too.”

“You know I can,” Zeryn answered as they left their tearful mother in her bed.

---

Part 5: Desperation

Xyla, now alone in her dark bedroom, found herself unable to stop the flow of terrible thoughts through her head.

I could leave them, she thought. I could just pack what I need and slip away in the middle of the night. They would never find me.

But the children would almost certainly go, or be taken, to the authorities, at which point Xyla would be wanted for child abandonment. Hiding her identity would become impossible if law enforcement were actually looking for her. And if the children were given a medical exam, which they probably would be, the DNA test would reveal their parentage. Xyla couldn’t stand the thought.

The truth was, there was no way out as long as she and the children were alive. Which led her to an even darker thought.

She could kill them. She was no match for them physically, of course, and trying to stab them to death in their sleep would be too risky, but she could poison their food.

She quickly put the thought out of her mind. There was no good way to get rid of a body, let alone two, in the City. Between the dense population and the many cameras that monitored every outdoor space, it was virtually impossible even to litter—never mind dump a corpse—without being noticed.

And even if none of that were true, she knew she couldn’t do it: not to any child, regardless of their faults.

That left only one route of escape from her nightmare. But she couldn’t do that, either. Even if she could muster the nerve to kill herself, it would be wrong. Life was sacred, even hers.

***

The next night was the same—the twins fed and felt her up, then Zeryn raped her while Yori held her down (even though Xyla didn’t struggle) and masturbated to the sight. Xyla was humiliated. Her children OWNED her now. Her body was just something for them to feed from and play with and penetrate whenever they wanted. And they wanted, every night.

Feeding and fucking became their routine for the next week. As the week went on, though, the emphasis became less on feeding and more on fucking or otherwise playing—often painfully— with Xyla’s body. After a few nights of raping her missionary style, Zeryn switched to mounting her from behind while Yori pinched and tortured her tits from beneath.

At the end of the week, the twins just took a few pulls of her milk each before Zeryn fucked her and Yori began masturbating and playing with Xyla’s tits. That night, as Zeryn came, Yori grabbed Xyla’s breasts and gripped both of them so hard that milk squirted everywhere, soaking the bed, until Yori had squeezed out every last painful drop.

The next night, though, things went rather differently. After the twins got their few gratuitous sucks of milk, Yori turned over on all fours and waited.

“Sorry, mommy,” Zeryn said, “but Yori called dibs on me tonight.” Then he climbed over Xyla and kneeled behind his sister.

Xyla didn’t know whether to be relieved or nauseated. At least she wasn’t being raped again, but the thought of Yori and Zeryn having sex in her bed, right in front of her, was vile. She knew they wouldn’t let her leave, so she turned her face away and closed her eyes.

“No! You WATCH!” shouted Yori, grabbing Xyla under her muzzle and forcing her head to turn around. Yori was more than angry; she sounded almost tearful. “You watch us love each other!”

So Xyla watched, choking back her disgust, as Yori got back down on her elbows and Zeryn entered her from behind.

Almost instantly, the rage on Yori’s face melted away. She let out a hushed gasp, and then, faintly, smiled. Xyla couldn’t remember the list time she saw a smile on Yori’s face that wasn’t edged with cruelty. Looking up, she saw nearly the same look on Zeryn’s face—no malice, no vicious lust, just something that looked like…not quite happiness, or satisfaction, but something in that direction.

Zeryn moved slowly in and out of Yori, holding her hips not with the savage, bruising grip he used on Xyla, but just firmly enough to help his sister move in time with him, maximizing his penetration with each stroke. Each of them screwed their eyes shut as though they were concentrating solely on the feeling of fucking each other. With every stroke, they softly vocalized in unison, “Ah, ah, ah, ah….”

They seemed to be in no hurry to reach orgasm. They fucked, and fucked, and fucked, never tiring, never changing positions or their expressions of almost-bliss.

Finally, after more than twenty minutes, Zeryn accelerated his pace, and soon he and Yori came, screaming. Then they fell on the bed, Zeryn on top of Yori and knotted inside her.

Yori turned to Xyla and said, “See how Zeryn loves me?”

Zeryn added, “Why can’t YOU love us, mother?”

Xyla was too shocked and disgusted to speak.

***

And then, the following afternoon, she went out to the store for a few things she couldn’t get online. When she came back to her apartment, the twins weren't there.

"Yori? Zeryn? Where are you?" she called nervously, fearing that this was a prelude to some sort of cruel trick. There was no answer.

She went to their room. Their shared closet and some of their dresser drawers were open, and various articles of clothing were missing. Their bookbags were gone, too, although the books they once held now lay scattered on the floor--replaced, presumably, with clothing.

In the kitchen, a couple of cabinets were open. Most of the canned goods that had been stored there were gone. That made it clear that they hadn’t been kidnapped, or taken by Social Services.

It was obvious now: Wherever they had gone, they had done it of their own free will, with at least a week’s worth of food.

Did she dare to believe it? That they had left, maybe for good?

She dropped to her knees among the discarded books. With closed eyes and clasped hands, she whispered, “Thank you, thank you, thank you,” over and over again.

---

Part 6: Surprise

It had been almost a year and a half since her children had disappeared, and when Xyla was honest with herself, she felt nothing but relief. No more moving from sector to sector of the City; no more hiding and living in fear; and no more sexual abuse and humiliation at the hands of her own children.

She still had to lie, of course--she couldn't tell anyone her real name or talk about her real past, especially the twins--but at least now they were the same lies, told to everyone consistently. Maybe, when she had told them long enough, they would start to feel like the truth.

She was done with her day's work--another eight hours of peaceful monotony, tracking records at a law firm--and she was coming home for a quiet evening of dinner and reading or television. She didn't have very many friends to socialize with, but that seemed necessary; a smaller social circle meant fewer chances to give herself away accidentally.

Xyla unlocked the door to her apartment, where she had moved a couple of weeks after Yori and Zeryn disappeared. It was small, but it was cheap and safe, and she was one of hundreds of anonymous residents who minded their own business and made no connections with one another.

She turned on the light in the main room as she locked the door behind her. She turned, and there they were on the sofa.

They had changed quite a lot. When she had last seen them, they were still children, but now they looked like young teens. Both were growth-spurt tall and slim, with more than a hint of wiry muscle, and Yori now had small, perky breasts. But Xyla couldn't mistake those faces--sleek muzzles, eyes like hers, and that expression that always hovered somewhere on a continuum between amusement and malice.

Her eyes flicked toward the door.
 
"Don't run, mother," Zeryn said, lounging next to his sister on the couch. "Where would you go?"
 
"And who would you say you were running from?" Yori added.
 
"Wha-What are you doing here?"
 
"We just need a place to stay for a month or so," said Zeryn. "So we thought we'd come see our dear mommy."
 
"You weren't that hard to find," Yori noted. “And I can’t say I’m that impressed with your complex’s security; your locks and cameras are good, but it took only a couple of fake IDs, a blowjob, and a veiled threat to get your building manager to give us a copy of your key.”

“It’s nice that the walls are soundproofed for privacy, though,” Zeryn added, smiling slyly. “We wouldn’t want anyone interrupting the more fun parts of our-” he ran his hand over his crotch “-reunion.”

Yori got up from the couch, walked over to Xyla, and took her hand, gripping it firmly as she looked her mother in the eye.
 
"We've learned a lot about ourselves since we went to live among the Ferals," Yori said. Xyla's eyes widened in disbelief, but she said nothing.

"A LOT," Zeryn repeated.

"For example," Yori continued as she led her mother toward the couch, "did you know that all Feral females are bisexual? It's how we bond"--she squeezed Xyla's hand a little harder--"and how we show dominance.”

"Speaking of which," Zeryn said, still in a relaxed pose on the couch, "take off your clothes."

Xyla took a step back, shaking her head rapidly in reflexive panic.

"Mother," Yori said, moving so close that her young breasts pressed against Xyla's, "I was as strong as you when I was four. How strong would you guess I am now?"
 
Xyla swallowed, wide-eyed.

"Let's go to the bedroom," Zeryn said. "I know it's not the same one, but maybe it will feel like old times, anyway."
 
Yori easily dragged Xyla back to the rear of the apartment and into her small bedroom. Then she held Xyla still.
 
"Now," Zeryn said, "if you promise to act like a good, loving mother and do everything we want, then Yori will take your clothes off. But if you don't, she'll RIP them off, and they'll be ruined. What do you say?"

"Please," she begged, using the only gambit she could think of. "You're...you're both grown and beautiful now. You can have anyone you want. You don't have to rape your mommy."
 
"Oh," said Yori, "I suppose that's true. We don't have to."
 
"We just want to," Zeryn finished.

"We didn't get nearly enough love from you as children," Yori explained. "Feral females don't just bond sexually with each other; they do it with their offspring, too."
 
"That's disgusting," Xyla said, looking at the floor.
 
"No, mother, it's being alive. It's FEELING. Something most Civils aren't good at--especially you."

Zeryn took off his shirt and added, "But don't worry; we're going to make you feel something right now."

Yori went over to Zeryn and unfastened his pants for him, letting them fall to the floor and taking hold of what was inside.

"Isn't it beautiful, mother?" Yori asked, showing her Zeryn’s cock as if it were a precious objet d’art.

Xyla couldn’t believe it—Zeryn’s penis was literally twice the size it had been when she’d last been forced to see it. Now, it was more than ten inches long, bevel-pointed, and thick, with a tennis-ball-sized knot at the base. And he was going to put it…

Zeryn interrupted her horrible thought. "Does it remind you of the ones our fathers had when they made us inside you?"

Xyla gasped. She had never given the twins the slightest hint about how they had been conceived.

Yori must have seen the shock on Xyla's face. "Oh, we've heard the story, mother. It was so...inspiring...that I had to ask some of the Feral males to fuck me right then and there."

"Speaking of fucking..." Zeryn said impatiently.

"Oh, I'm sorry, Zeryn," said Yori. "Let's get that nice big cock of yours into mommy's cunt. I'm sure it's missed you."

Xyla was too frightened to move, so Yori simply took the passive woman's clothes off, starting with her shirt and bra.

Yori paused to take a good look at her mother's breasts. "I see you haven't lost much size since we stopped feeding from you, mother."

Xyla looked at the floor. "I suppose you're proud of making me look like this," she heard herself say.

Strangely, the accusation incited no anger at all. "YOU should be proud, mother," Yori said. "Feral females consider big breasts a badge of honor; they show that a female has given children to her band and that she can feed those children well."

Xyla tried to avoid showing her disdain for such a primitive notion. It didn't require a great deal of effort; Xyla was too consumed with fear over what was about to happen as Yori stripped her of her skirt and panties.

Once Xyla was naked, Zeryn said, "Lie down on the bed, mother. I want it to be like our first time was."

"With one big difference," Yori added, momentarily fondling Zeryn's erect cock when she spoke the word "big." Then Yori quickly shucked off her own top and skirt. She wore nothing underneath.

Helpless, Xyla lay back and began weeping.

"Don't you DARE cry!" Yori shouted. "Zeryn's love is a gift. You should be grateful!"

"Sis, let’s not get into that," Zeryn said in a tone that was half pleading, half warning.

"I'm sorry, brother," Yori said. Then she turned to her mother. "Now open wide and take your cock like a good mommy."

Xyla, trying to stop the flow of her tears, began to spread her legs.

"Wider, mother," Zeryn ordered. "And raise up your knees. I like to get in deep."

"Mmm..." said Yori, massaging her crotch and, apparently, reminiscing.

Xyla obeyed. Zeryn smiled and picked up his pants from the floor. Tied to the belt was a small hide pouch that Zeryn reached into with two fingers to extract a greasy brown gel--the very same substance Xyla's Feral rapists had used to lubricate her years before.

"Rendered animal fat, with kelberry juice as a preservative," Zeryn explained. "Every Feral male carries it; you never know when you'll need it."

"And Zeryn needs it quite a lot," Yori added proudly.

Zeryn knelt on the bed between Xyla's legs and smeared a fingerful of the grease inside his mother's cuntlips, making sure to get some of it inside her hole. Then, with a wolfish smile, he mounted her and positioned his cockhead against her entrance.

"Zeryn," Yori half-moaned, rubbing her pussy a little harder, "I never get tired of watching you do that. Especially when it's our mommy."

“And I love it when you watch, Yori. Now watch this.”

Zeryn began sinking his thick phallus into Xyla’s tight hole. Xyla was too afraid to scream or fight back; she just gripped the sheets as she moaned in pain, anguish, and humiliation.

“Oh, fuck, yes,” Zeryn said. “She’s so much tighter now that I’ve got my adult cock.”

“I love your cock, Zeryn,” Yori said with feeling. “Make her love it, too.”

Zeryn forced more and more of his thick member into Xyla as she writhed and whimpered in pain and shame.

“Please…” she begged pointlessly, mindlessly.

“Please what, mommy?” Zeryn replied. “Please give you more cock? Of course I will—there are still four inches left to go.”

“Not including the knot,” Yori added. “Or did you mean, ‘Please squeeze my big tits like you used to’? Because I’d be happy to.”

Yori grabbed her mother’s breasts and began kneading them roughly, smiling like she was playing with some wonderful, long-lost toy.

Zeryn got his cock in all the way to the base of his knot, then started to fuck his mother’s cunt, slowly but forcefully. The beveled end of his thick penis pressed painfully against her cervix at the end of every slow stroke, as if Zeryn were trying to force his way into her womb. Xyla began crying again.

Yori grabbed Xyla’s nipples, squeezing them just hard enough to threaten harm. “Why are you crying NOW, mother?”

“It hurts!” Xyla shouted.

“It wouldn’t hurt if you’d accept Zeryn inside you instead of fighting him.”

“I’m not fighting him!” Xyla cried through her tears. “I’m doing everything you want!”

Inexplicably, Yori flew into a rage. “NO YOU’RE NOT!” she screamed.

“Yori,” said Zeryn, “seriously, cut it out.”

“I’m sorry,” Yori said, clearly straining to calm herself. “I’m sorry. Keep fucking her, Zeryn.”

Zeryn grabbed Yori and gave her a big tongue kiss even as he continued to thrust into Xyla. Yori seized her brother’s shoulders and kissed him back, hard. There was something almost desperate in it.

When they released each other, Yori said, “Thank you, Zeryn.”

“Of course, sis.”

“Now,” said Yori, “where were we?” Then she grabbed Xyla’s breasts and squeezed them as hard and painfully as before. Xyla cried out but was now too confused and frightened even to beg for mercy.

Zeryn began thrusting harder and faster, still hurting Xyla inside with every stroke.

“That’s it, mommy,” he growled as he plunged into her again and again. “Take it all inside you. Take it nice and deep.”

“That’s right, you fucking bitch,” Yori added, pulling harder on Xyla’s nipples. “You take Zeryn as deep as he wants. You let him inside your fucking womb, if that’s what he needs.”

Xyla began crying again. This only drove Yori to abuse her nipples more cruelly and Zeryn to fuck her harder.

Soon, Zeryn gasped, “I’m gonna come…I’m gonna fill you up, mommy…”

Xyla’s eyes flew open in panic. “No! Don’t! I’m not on any birth control!”

“Relax, mother,” Yori said, still twisting Xyla’s nipples painfully. “Ferals don’t have the same genetic issues that Civils do. Two close relatives can’t have a baby.”

Deep down, Xyla knew it was a lie. But it was much, much easier to accept the lie than to face the possible truth.

“YAAAAAAAAAH!” Zeryn screamed and thrust his knot into Xyla, making her shriek with agony. He pumped and pumped semen into her, thick and potent and painfully hot, just like that of the males who had first raped her.

“Ah, fuck, yes,” Zeryn breathed as he collapsed on top of his mother, rooted inside her, still filling her with his come. Xyla sobbed beneath him.

“Oh, cheer up, mother,” Yori said viciously. “You’ve got your babies back for a whole month.”

“It’s so good to be home again, mother,” Zeryn said. “Just think of all the loving you’re going to get.”

Xyla only wept more loudly.

Part 7: Pain

That night, they didn’t remain in the bedroom; Xyla’s bed was too small for the three of them, so the twins insisted that Xyla spend her nights on the living room floor with them.

“That way, we can spend more time together,” Yori explained with matter-of-fact cruelty. “Besides, Zeryn gets horny in the middle of the night, and I really need to catch up on my sleep.”

The twins also explained that Xyla would not be leaving the apartment for the next month. She would call in sick the next morning with an infectious disease, and she would work from home instead. It wouldn’t do to have her go into work, where people might see her and ask why she looked tired, or why she was walking funny.

The next three days were nightmarish. Not only did Zeryn always rape Xyla at least once during the day, but every night she would wake up to the pain of him penetrating her, raping her awake and then knotting her and filling her with come before he would let her go back to sleep.

The rest of their routine was bizarre, as well. The twins would wake up late, eat a huge breakfast, then lounge around for a bit, reading or watching television—mainly news. Then they would exercise, typically by wrestling with each other, which almost always ended in the siblings having loud, rough sex on the living room floor. Xyla, working at her desk in the bedroom, would stuff pieces of tissue into her ears to try to block out the sound.

In the evenings, well after dinner, the two would go out. They never told Xyla where, but given how they dressed and how late they would stay out, she guessed they were going to dance clubs or something similar. Then they would come home after Xyla had fallen asleep (in the living room, as they required) and pass out until late the next morning—except for Zeryn’s spontaneous rapes of Xyla in the wee hours when he was too horny to sleep.

On the fourth morning of their visit, the twins were in the kitchen, making their breakfast. Xyla was glad that at least they weren’t forcing her to cook for them.

Zeryn called, “Mother, come to the kitchen. And there’s no need to dress first; anything you wear will just get ruined.”

Ashamed, she obeyed. Both of her children were naked, and her son was clearly in a randy mood, feeling up her breasts and bottom the moment she stepped into the apartment’s kitchen area. The kitchen was separated from the living/dining room by a stainless-steel counter.

“Are you going to rape me again?” Xyla asked, afraid but unable to stop herself from speaking. “Is this what it’s like among the Ferals? Violence and cruelty and rape? Yori, do the men just rape you whenever they want?”

“Oh, mother, no worthy Feral male would HAVE to rape me.” Then, baring her fangs, she added, “And no unworthy male COULD.”

“Besides,” said Zeryn, toying with Xyla’s breasts, “it’s nothing like the Feral Films they show on subscription television. There are occasional skirmishes between bands, but we basically live in peace.”

“Rape is mostly for Civils,” Yori added. “Feral males aren’t particularly disposed toward violence against their own females, and Feral females aren’t nearly so repressed.”

“But how do they treat YOU?” Xyla asked. “You’re half Civil; you must be freaks to them.”

For a moment, something like doubt flickered across Yori’s face. Then her familiar arrogance returned.

“On the contrary, our Civil blood makes us...desirable, in certain ways.”

“Yori here is very popular,” added Zeryn.

“It’s true,” Yori replied. “I have males lining up to fuck me. Sometimes literally,” she added with a smile.

“You’re a slut,” Xyla blurted, looking at the floor.

“No, mother, I’m a woman.”

“You’re not even six years old! And even you were as old as you look, you’d still be a child!”

Xyla clapped a hand over her own mouth. Why did she keep saying these stupid things that would only make the twins angry?

“Why do Civils want to put everything off?” Yori asked. “Adulthood, responsibility, mating, childbirth, even death—you forestall every one of them for as long as you can.”

“Maybe it’s their lifespan,” Zeryn mused even as he started tugging playfully on Xyla’s nipples.

Xyla tried to ignore Zeryn’s hands. “I’ve heard that Ferals rarely live past forty,” she said. “I suppose that makes them want to do everything as early as possible. If they would just embrace modern medicine, clean food and water…think how much better their lives would be.”

“Mother, longer is not better,” said Zeryn. “Do you know what Ferals call their race? The Living. And they call Civils the Dead. In their eyes, your lives are sterile, empty, pointless. They would rather live to the fullest for a few decades then spend a hundred years living in little boxes stacked on top of one another, hiding from the world.”

“Barely feeling,” Yori added, “barely mourning, barely loving.”

Zeryn slid his hand down to Xyla’s crotch. “Well, that seems like enough cultural conversation for one morning,” he said. Then he turned to Yori as he forced Xyla’s legs apart with his knee and started fingering his mother’s pussy. "Sis, I was thinking: calling her 'Mother' and 'Mommy' just doesn't seem adequate anymore."

"Hmm...” Yori answered, seemingly happy that Zeryn had changed the subject. “Did you have something else in mind?"

"How about 'Cuntmommy'?"

Xyla's eyes widened in horror. The rape and molestation were bad enough, but somehow, this was too much.

"Oh, yes, that's much more descriptive," Yori said. She turned to her mother. "Isn't Zeryn clever, Cuntmommy?"

Before Xyla could even think, she heard herself screaming, "Don't call me that!"

In a flash, Xyla’s back was against the refrigerator and Yori's hand was on her throat.

"Look, Zeryn, Cuntmommy acts like she has a spine instead of just a cunt. Now we're going to have to punish her."

"Well, she DOES have more than just a cunt, Yori. She also has an asshole."

Xyla froze with terror.

"Oh, Zeryn," Yori said, "you are just SO full of good ideas."

"Cuntmommy is about to be full, too."

Yori stepped back and allowed Zeryn to grab Xyla by the hair and drag her to the kitchen counter. He forcefully bent her over it, pushing her down until her big breasts were mashed against the cold stainless steel.

Ever helpful, Yori opened a few kitchen cabinets until she found some vegetable oil. "Here, brother, let me take care of you. You’re already running out of the lube you brought, and I don't want you hurting that beautiful cock of yours while you're trying to shove it into our insolent Cuntmommy."

"Sis, you are the sweetest girl ever."

Yori poured a little oil into her hand and then obscenely spread it all over Zeryn’s erect wolf-cock, sliding her hand up and down its length a bit more than necessary, coating every last square millimeter and spending extra time caressing his thick knot.

Then she moved her hand to her mother’s vulnerable rump. Xyla struggled helplessly as Yori’s oil-slicked finger entered her anus and pumped in and out a few times.

“Tight,” Yori said, pulling her finger out and cuddling up to her brother. “You’re going to have fun in there. Mommy, not so much.”

“Please!” Xyla screamed. “I’m sorry! You can call me Cuntmommy. You can call me anything you want!”

“And we will,” Zeryn said. “Right after your punishment.” He put the pointed tip of his wolf-cock against her pink anus.

“DON’T! Please, it will never fit!”

“Don’t worry, Cuntmommy,” Zeryn said, “I’ll MAKE it fit.”

He began to force the head of his cock in, ignoring Xyla’s howl of agony. His nearly conical cockhead seemed the perfect tool for forcing open an unwilling asshole; Xyla’s pink ring gradually stretched wide as Zeryn slowly but forcefully pushed his cockhead through it.

Once he got the head all the way in, Zeryn gasped, “Oh, Cuntmommy, your asshole is so beautifully tight, I could fuck it all day. Maybe I will.”

Xyla began to cry. Yori, enraged, grabbed Xyla by the muzzle and forced her mother’s eyes to meet her own.

“Always the fucking crying! You should be glad my brother wants to put his cock in you at all, you icy bitch!”

With the hard part out of the way, Zeryn was now sliding the rest of his ten inches into his mother’s anus. Xyla thought she had endured as much pain and shame as she ever would, but she was wrong; being sodomized in her kitchen, the cold steel countertop against her breasts as her own son’s cock traveled farther and farther into her bowels, was the most degrading thing that had ever happened to her.

All of which seemed to be turning Zeryn on to no end. The moment he got his whole cock (save for the knot) into her, he began fucking her ass hard and fast, thrusting deep into her bowels again and again as she screamed and cried and mindlessly begged him to stop.

He didn’t knot her when he came; he must have sensed that doing so would tear her open. Instead, he just gripped her ass tightly, his knot pressed against her violated anus, as he ejaculated what felt like a quart of thick, searing-hot semen into her gut.

Zeryn leaned over her, his front pressing against her back, his cock still buried in her ass.

“Learn your lesson yet, Cuntmommy?” he said. “No backtalk.”

Xyla couldn’t even reply. Her throat was sore from crying and screaming.

Zeryn pulled out, and Xyla could feel his semen gushing from her anus onto the kitchen floor. One more humiliation.

“I hope you liked that, you fucking bitch!” Yori said angrily. She pulled back her hand and slapped Xyla across the face, hard.

“Yori, what’s the matter?” said Zeryn. There was genuine concern in his voice.

“I want to hurt her too!” Yori cried, somehow upset.

Zeryn went around to the other side of the kitchen counter and put his arms around his sister. “Sweetie, you can hurt her all you want,” he said, clearly trying to reassure her.

Yori looked in his eyes. “I want to hurt her the way you do,” she said, voice quavering. “I just wish I could make her…FEEL me, like you can.”

Zeryn held her closer. “I know, baby, I know. It’s not fair.” Then he lifted his head. “I think I know what will cheer you up.”

He went over to where Xyla still lay over the kitchen counter, her face in a small pool of her own tears. Zeryn grabbed Xyla by the hair and jerked her head up.

“Lie down on the counter,” he commanded.

She hesitated for the barest moment, then wiped her eyes and did as Zeryn said.

“Now,” Zeryn said, “you’re going to eat your daughter’s pussy.”

Yori looked at him. “Oh, Zeryn, that’s so sweet.”

"It's the least I can do, sis, after all the times you held her down for me," Zeryn said as he helped Yori up onto the counter.

"Even so, I'm going to suck your cock after this."

"You'd do that anyway," Zeryn said.

“I can’t help it,” said Yori. “A stomach full of your come just feels like love.”

“That’s because it is,” Zeryn answered, reaching over to play with one of Yori's nipples the way she liked as the girl squatted over her mother’s face.

“Now lick me, Cuntmommy,” Yori commanded, “or I’ll shove your muzzle up my pussy, and then you can forget about breathing until I come. If you last that long.”

It was a rough morning for Xyla.

Part 8: Hopelessness

It had been twenty-five days since the twins arrived. Twenty-five days of rape, forced cunnilingus, pain, and humiliation. The only thing that kept Xyla going was the fact that the twins were only planning to stay for a month. Soon it would be over.

It was mid-afternoon, and Xyla had just emerged from her bedroom office to get a glass of water from the kitchen. The twins weren’t in the living room as usual, but the bathroom door was closed. She could hear voices from behind it. That was odd—the twins never spent time in the bathroom except when they scrubbed each other’s backs in the shower (an act typically followed by loud shower-sex).

She crept over to the door. She was terrified of getting caught, but something inside her insisted on hearing what the two siblings were saying.

“Sis, it’s never going to work,” she heard Zeryn say.

“Can’t we at least TRY?” Yori replied, sounding upset. Not angry-upset. but sad-upset, which was unusual.

“All right, but you have to promise not to get too emotional if it doesn’t work.”

“I promise. I just need to know.”

“Okay. Just remember that I love you.”

“I love you, too, Zeryn.”

Sensing that their conversation was over, Xyla moved as quickly and quietly as possible toward the kitchen. She was already filling a water glass from the sink when the twins emerged from the bathroom.

“Mother,” Yori said, not calling her “Cuntmommy” for the first time in three weeks, “come to the bedroom.”

She bolted her water and obeyed, bracing herself for yet another session of rape and abuse. When she got to the bedroom, she awaited Zeryn’s usual order to lie down and spread her legs, or to get on all fours on the bed.

Instead, Zeryn kissed her. Not the way he usually did—forcing his tongue into her mouth, hands roaming everywhere—but softly, only barely applying pressure. Then he backed away, and Yori kissed Xyla the same way. She moved closer, her body up against Xyla’s, as Zeryn moved around and gently pressed his own body against Xyla’s from behind. His hand stroked her shoulder and arm as his other hand stroked Yori’s. He kissed her neck, nipping gently, as Yori’s hand moved up to Xyla’s breast and caressed it softly.

It was revolting.

Xyla broke off her kiss with Yori. “What are you doing?”

“We’re- we’re trying to be nice,” Yori said.

“We’re trying to… make love to you…like Civils do,” Zeryn explained.

Xyla thought she might throw up.

"Why?" Xyla said, starting to sob. "Why can't you just leave me alone?"
 
"Because we love you, mother," said Yori, almost pleading.
 
"No you DON'T!" Xyla screamed. "You're MONSTERS!"
 
For the first time since Yori was a tiny child, Xyla actually saw tears come into her daughter's eyes.

"You- you don't understand," Yori said, clearly trying to keep from crying. "You NEVER understood. We wouldn't be...monsters...if you'd loved us right."

"Please, sis," said Zeryn, sounding a little choked up, "you said you weren't going to do this."

"I can't help it," Yori quavered. "I can't just keep holding it in! And neither can you. We have to explain."

Zeryn turned to Xyla. She could see tears welling in his eyes, too.

"We needed something, back then," he said. "And we couldn't tell you what it was, because we didn't KNOW."

"We needed your love," Yori said. "Not cold, sterile, Civil love--we needed the kind of deep, limitless, sexual love that Feral mothers give their children. And when you wouldn't give it to us, we had to take it. We didn't know another way."
 
Xyla shook her head in denial. "No, no. It was never about love…You were greedy, and- and cruel. I could never give you anything without you wanting to take more, to twist it into something sick."
 
A tear escaped Yori's eye. "It's- it's because you were weak, mother. Weakness sets off something in Ferals, something…primal. We can FEEL weakness, and we can't help but hate it. Ferals have to control the weak, dominate them, hurt them."

“It was especially hard for Yori,” Zeryn said. “To live day in and day out with a female who is as weak as you are…you have no idea how much she had to hold herself back, to keep from hurting you more than she did.”

"We needed you to be strong," Yori said through her tears. "We just didn't know that."

Xyla was horrified--partly because, in a sense, Yori and Zeryn were right to be upset. She had brought them into the world because she was too afraid of the alternative, but she was also too afraid to think about what bearing two half-Feral children would really mean, or to ask anyone for help. She had hoped she could raise them as normal, Civil children, but she hadn't had the first clue what they would be like, or what they would need.
 
She sank to her knees. "I'm sorry. I didn't...I..."
 
Yori grabbed Xyla by her upper arms and yanked her to her feet.
 
"NO!" Yori half-shouted, half-sobbed. "I don't WANT you to be sorry! I want you to be STRONG! I want you to LOVE ME! I want..." Her sadness and fury choked her off.

"It's no good, sis," said Zeryn, wiping his eyes. "She'll never be our mother...not the one we needed. She's too weak, and too cold, even now."

Yori looked down, trying to rub the tears from her eyes and cheeks. When she looked up again, right at Xyla, her red-rimmed eyes were filled with rage.

“Then RAPE HER! Rape her harder than you ever have! Make her hurt deep inside the way WE DO!”

Yori pulled back her fist to punch Xyla in the face. Xyla started to cringe, to try to avoid the blow, but Zeryn grabbed Yori’s fist and forced her fingers open.

“We can’t hurt her too much, remember?” he said urgently.

Yori slapped Xyla’s face, then again, and again, as hard as she could, screaming her fury. Then she forced her mother down onto the bed on her back. Yori tore off her own underwear and grabbed Xyla’s muzzle, holding it closed.

“You fucking bitch,” Yori sobbed. “You fucking, fucking bitch!”

Yori mounted Xyla’s face and, as she had threatened to do weeks before, forced her cunt down onto Xyla’s muzzle, shoving it inside. Xyla found herself staring at Yori’s clitoris and completely unable to breathe.

“Yori, be careful!” Zeryn warned.

“Just for a minute,” Yori begged. “Please, let me do this just for a minute. I NEED to!”

“I know, baby, I know,” Zeryn said, dropping his pants. “Look, I’m going to rape her, okay? Just like you want.”

Yori lifted herself up, then savagely thrust her hips downward, burying her mother’s muzzle as deep in her cunt as it could go. Then Yori did it again, and again, and again as her mother flailed beneath her.

Zeryn thrust his cock into Xyla’s cunt and began fucking her hard, battering her cervix more brutally than ever before. Even as he shoved his cock into Xyla’s flailing body, he shouted, “Yori, get off her!”

“Please, just a little longer…” Yori begged, still fucking her mother’s face with her cunt.

“Get off her NOW! You’ll kill her!”

Choking back tears, Yori lifted herself up and freed Xyla’s muzzle. Her mother gasped desperately for air.

Yori climbed off Xyla and then went over to Zeryn, grabbing his ass and pushing it forward rhythmically, helping him fuck, shoving him into Xyla with every raping stroke.

“You make sure she’s good and pregnant,” Yori sobbed. “You knock her up just like all those other Civil cunts you fucked since we came here. You MAKE her have your baby! MAKE HER!”

Zeryn raped Xyla hard, grunting with every thrust as he forced his cock as deep into her as it could possibly go. Even he was starting to be overcome with rage.

“Take it you fucking cunt! I’m gonna fill you with so much come your baby’s going to be born pregnant! YOU TAKE MY FUCKING COCK!”

Zeryn came and thrust his knot as hard as he could into Xyla, making her scream. Yori smiled tearfully, like it was the most beautiful sound she had ever heard. Then she kissed Zeryn hard, plunging her tongue into his mouth, suddenly desperate for him. Zeryn kissed her back just as hard, his hands grabbing her ass, his fingers probing her cunt and asshole the way she enjoyed.

Despite the pain and shame of being knotted and of yet another enormous load of Zeryn’s burning-hot semen flooding her womb, Xyla was watching Yori’s face. She could see that Zeryn’s touch wasn’t just pleasing the girl; it seemed to be comforting her, too.

Yori grabbed Xyla’s tits and squeezed them painfully hard. “That’s right, you look at us! You look at what real love is—something you’ll NEVER feel, you numb cunt!”

After a few minutes, Zeryn’s knot went down, and he pulled his cock out of Xyla. As usual, thick semen flowed like a river from her cunt. Yori fell on the bed and began eating it straight out of Xyla’s cunt, swallowing gob after gob of it like it was beyond delicious—like it was precious. Then, after consuming nearly a pint of her brother’s come, she thrust two fingers deep into Xyla’s pussy and scooped out an extra-large helping.

“Open your mouth,” she said to Xyla, her voice ice cold.

Seeing Yori’s unprecedented fury, Xyla was too afraid to disobey. The moment her lips parted, Yori shoved her fingers into Xyla’s mouth and deposited the gob of semen in the back of her mother’s throat.

“That’s what my beautiful brother tastes like, you fucking bitch,” she said, still teary with rage and sadness. “That’s the closest you’ll ever get to tasting what love is. Now you fucking swallow it.”

Xyla did as she was told, trying not to cry—or vomit—and make Yori even more angry.

“It’s time we left, sis,” said Zeryn. “We’ve done what we came to do, and you’ve suffered enough, being here.”

Yori stood up. “You’re right, brother. It’s time to go back.”

Even after all the torment, even as relief cascaded over Xyla at the thought of the twins finally leaving her alone, she couldn’t stop herself from speaking.

“You said, ‘go back,’” she observed tearfully. “Not ‘go home.’”

Zeryn cast his eyes downward. “We don’t…exactly…fit in, out there. Even with the band that fathered us. We’re too different.”

“And we don’t have a mother,” Yori added. “Fathers don’t matter very much among the Ferals; most don’t even know which male of their band sired them. It’s your mother that gives you status, and as far as they’re concerned, we don’t have one.”

“Then why do you stay with them?” Xyla asked.

“They may not fully accept us, but they’re good to us…because they need us,” Zeryn explained. “We’re part of their plan.”

“Great God,” Xyla said. “Are they planning some kind of invasion?”

“No, mother,” Yori said. “As amusing as Civils might find it to watch on the evening news, the Ferals are not planning to charge the gates with their spears to be mowed down by a handful of Civils with autorifles.”

“But they DO hate Civil weakness,” Zeryn said. “So they’re attacking it with the most powerful weapon they have—their blood.”

“Ferals and Civils don’t interbreed very easily,” Yori explained. “It was great luck that our fathers managed to impregnate you, and a handful of other Civil females. The next generation, the ones fathered by Zeryn and the other half-Civil males the Ferals have managed to sneak into the City over the years—mostly with help from Civil sympathizers—that generation will be only a quarter Feral.”

“They’ll fit in better,” Zeryn added. “They won’t grow as fast, won’t have the same…issues we had. But they’ll still have the spark of life, real life, inside them. And they will spread that spark throughout the City until it burns to the ground.”

“And when they emerge from the ashes, the quarter-Civils born outside the walls will be there to greet them—and breed with them,” said Yori, putting a hand on her stomach. Looking closely, Xyla could see the barest curve of pregnancy. Her eyes flicked to Zeryn.

Yori seemed to notice this. “No, mother, they’re not his. Probably not, anyway; I’ve mated with every male in our band many, many times. I’m part of the plan, too, you see.”

“The point is, mother,” Zeryn concluded, “the Ferals are going to eliminate Civil weakness forever. And in the end, Civils and Ferals will be one people again.”

Xyla had no idea what to say. Together, the traumas of the day and this new information were too much to process.

“Goodbye, mother,” said Yori. “We won’t be back. I just can’t be around you anymore.”

They didn’t pack any of the clothes or other possessions they had brought. Xyla supposed they were just Civil camouflage, anyway; the twins wouldn’t need them outside the walls of the City. The twins simply took each other’s hands, and went.

She was alone now. Blessedly alone.

But not forever. Xyla had no doubt that she was pregnant again, and this time, her pregnancy was not just the product of rape, but of incest, as well.

But that wasn't the baby’s fault.
