But I loved my wife, and I trusted her, and I had no way of predicting or even understanding the powers that would influence our lives. Rita has been the love of my life for many years. And what's not to love. She's an attractive blond, a real natural beauty with a slim body, perfect, small breasts, and a tight ass. But more than that, she's intelligent and witty, and at 34, she's one of the youngest professors at the college. I had never seen her so proud of herself the day she came home and told me about Vanya. Vanya was the talk of school from the moment he arrived. He had recently immigrated from Russia, looking for a better education than his mother country could give him, and had chosen my wife's college out of the seemingly endless list of possibilities. A Mozart of chemistry, they called him. And after finally snagging him, the school assigned Rita to tutor him in English. He could write it at an acceptable level, but his spoken usage was still poor. It was decided that they would meet at our house for an hour, four nights a week. He was a smart kid, and should be able to learn quickly enough. There was something about Vanya that I didn't like from the first moment he walked through our front door. I had at the time passed it off as jealousy. I don't know what I was expecting from a Russian chemist, but it certainly was not the tall, dark and very fit young man. He looked more like a model or actor than a would-be scientist. At 21, Vanya was at the peak of his sexual virility. Had I paid closer attention, I would have noticed Rita's instant attraction or the gleam in his eyes as he looked over my wife's tight form. Instead, I shook his hand, covering my wince at his tight grip and went back to the television. I did not turn to see Vanya staring at Rita's ass as she led him into the kitchen to get to work. Over the next two weeks I remained oblivious to what was transpiring in the next room. Rita changed a little, in her love making at least. She became more assertive and demanding, wanting sex whenever she could get it. It was not like I was in a position to complain. I just chalked it up to her excitement at the honor and trust the school had given her. Had I paid more attention, I might have seen Vanya discreetly adding small douses of a powder to her drinks whenever they studied together. I may have noticed how he spoke in a commanding tone, both ordering and influencing her mind as the chemicals he fed her slowly took effect. I would have thought twice about how my wife's clothes during their lessons were becoming less formal and more casual. And I am certain, had I been a more attentive and protective husband, I would have seen and stopped Vanya's first physical contact as he gently slid his hand along my wife's inner thigh. The touches became more bold as Vanya became more confident in his drug and its effect on Rita's mind. He touched her waist and stomach, and moved his hands over her tits, feeling her firm breasts through her shirt. When he moved his hand inside her blouse and under her bra to pinch her bare nipple for the first time, Rita moaned and shivered but never veered from her lesson. It all seemed a logical part of the tutorial session. That same night, just before it was time to leave, he made the final test of his control. He ordered her to stand up and remove her panties. She did without hesitation, and when she sat back down, she quivered as Vanya's hand slid up her thigh and touched her sparsely haired and neatly trimmed pussy. That night was one of the most passionate and frantic lovemaking sessions we had ever had. Had I noticed any of this, I would have been a fool to believe that a 21-year-old man would have stopped there. The very next night they got together, I was channel surfing on our big screen, looking for something to interest me. Less than fifteen feet away the lesson plan had taken a radical turn. Sitting close to her, Vanya spent the first few minutes with his hand under Rita's t-shirt, cupping her firm, bra-less breasts while she broke down some of the more complicated rules of our language. He stopped her speech by turning her had towards him and kissing her on the mouth. The kiss was returned with longing. His hands ran through her long, blond hair as their tongues fought against each other to be the first to explore the other's mouth. Vanya broke the kiss and whispered in my wife's ear. She giggled at his comment, then looked worriedly to the wall that I sat obliviously on the other side of. Vanya simply raised his eyebrows. That was all it took as Rita slipped to her knees and crawled under the kitchen table. She wasted no time in fumbling at Vanya's belt. He rose up enough for her to unzip his pants and pull them, then his underwear, down a few inches. She gasped audibly, the sound masked by the volume I always enjoyed the TV to be on. His cock twitched, then started to grow as she watched. At half-mast, it was already impressive. But as Rita reached out with her small hand and took hold of the hot organ, it rapidly grew its full 10 inches. Her small hand had no hopes of encircling its entire girth. She was an excellent cocksucker, even deepthroating me from time to time. But I was not the size of that monster. She continued to stare at it in awe until he finally tapped her on the head. Whatever inhibitions she felt at its size were shattered with that tap. She attacked his cock with a hungry need, slurping her mouth up along the side and over the head before opening wide and attempting to suck as much as she could in her mouth. As it was, only about half was going to fit inside the tight space of her mouth, but it was enough. She plunged her mouth up and down, pausing only to catch her breath or to suck his hairy balls in her mouth. Vanya gasped and groaned loudly, almost daring me to hear, as my wife went down on him. Like I said, she was an excellent cocksucker, and with five minutes she felt his cock swell only an instant before the first glob blasted her mouth. Several more quickly followed as his hot cum filled her mouth and leaked out the sides. She swallowed as much as she could, and the rest dribbled out onto her chin and clothes. I slipped quietly in to the kitchen for a drink, hoping to not bother them, just as Rita had finished wiping his cum from her shirt and was drinking a glass of water. She smiled sweetly at me and kissed me on the cheek and went back to her lesson. For the next week, even I noticed the tension that had grown between them. It was a stressed tension, but an uncomfortable tension that seemed to have been brought on by my presence. I had no idea my wife was sucking off her student every night, or that Vanya had started to become so bold as to even go down on my wife while I was watching the game. But for the first time in our marriage, I was beginning to question her loyalty to me. It was a small leap from suspicion to actively searching for evidence. And one evening while she was out, I did just that. I had never once even thought of reading my wife's email before, but as I poked through our study, her laptop seemed to scream at me. I flipped up the top to find that she left her connection to the college left on. Rubbing my sweating palms and looking around guiltily, I clicked her email icon. There was one email still in her trash bin that she had not fully cleaned out. My heart was now racing as I clicked on it and read the message from Vanya. It was a short message, mostly about school and her tutoring, but the final bit made my heart skip painfully in my chest. "It was so much crazy in the stairwell. You suck cock good. We sleep together soon, and I show you what real man is like. Vanya~" I couldn't believe it. My head swam with all kinds of thoughts of rage and retribution. I would kill them both. But those thoughts would have to wait as the front door opened. I quickly closed her laptop and did my best to avoid her for the rest of the night as I decided what to do. The next night, as Vanya entered, I stood up to get his attention. As he looked into my angry eyes, and I into his eyes, I saw that he knew I knew. The cocky bastard only smirked and gently caressed my wife's ass as he followed her into the kitchen, the wrongness of the act not even registering in her drug induced reality. But I didn't know about the drugs, the chemicals he was feeding her, not then. All I saw was my wife not even reacting to his intimate touch. I was beyond shock at the actions, but even more startling was the fact that I did not challenge them. Over the next hour I made every excuse possible to frequently enter the kitchen. My wife shifted nervously at every arrival. "Everything okay in here?" I asked as she squirmed in her chair. "Yes, dear," she answered, glancing at the doorway, trying to will me to leave with her eyes. "Everything is just fine." By the end of the hour, Rita was flustered with pent up desire. Vanya kept his cool, though, and never looked twice at me. He kissed Rita on the lips at the door, right in front of me. There was nothing I could say because the moment he left, she was on me. She wrestled me to the floor and pulled down my pants. Lifting up her skirt – the little tramp wasn't wearing panties – she dropped her soaking cunt down, sucking in my entire cock in one, quick plunge. Rita always liked slow, passionate lovemaking. That night, as she bucked and screamed on top of me, might have been the first night we ever fucked. I came quickly under her assault, and, stunned by my inaction, went to bed. The next day, Rita had left a message on our machine saying that her lesson with Vanya had been cancelled and that she would be late as she had a faculty meeting. Lost in my own thoughts, as I had been all day, I tried to find comfort in a book. Rita came home late, when I was already in bed, and left early. Having slept poorly, and still nursing a wounded pride, I called in sick at work and spend the morning in silent misery. I decided I would confront my wife that night. And if I did not get a satisfactory answer for what was going on, I was leaving her. I was fortuitous, or so I originally thought, that I was home during the day as a courier arrived with a package for me. It was a plain, brown envelope with something solid inside. I had barely shut the door before I ripped the package open and found a videotape inside. Looking around, as if I might find the person who sent it standing right beside me, I curiously moved to the VCR and pop the tape inside. Curiousity turned to dread as I turned the machine on and Vanya's face appeared on the screen. I don't know where he had filmed it from. It appeared to be a large and nicely furnished bedroom, and given the amount of excitement around the young student, it seemed reasonable that the college would have put him in a nice house or apartment somewhere. He beamed broadly as he settled back and looked into the camera. "Hallo," he sneered in his thick accent. "You know something is going on with yer weef. What you do not know is how mooch is going on. Yer weef is a wery gorgeous woman, and I knew I had to have her. And have her I will tonight. Sit back and enjoy the show." I should have turned it off, but I couldn't stop myself from watching. The filming broke for only an instant before starting up again. It was the same room but from a different angle, and it was obvious someone was carrying the camera around. My Rita was sitting on the edge of the bed. She was dressed in a short, cotton summer-dress. The white material made her skin glean on camera. Her face was composed as she looked up and smiled into the camera, but I could sense the nervousness posture. "Dis school offered me many perks," Vanya's voice spoke from behind the camera. "Yer weef was not one of dem, but I take anyway. My guest is on da way. And she will elp me to fuck yer weef tonight." As if on cue, there was a soft knock and the camera swung around and panned in on the door as it opened. A woman stood in the doorway and looked over the scene with an amused air. She was a call girl, most likely, and one of the perks the college had evidently provided. Dressed in a short, tight skirt and short-sleeve blouse that fought to contain her large tits, her makeup was heavily applied and her long, dark hair overly curled. She was attractive in a slutty way. She took the gum out of her mouth and boldly stuck it to the door jam before sauntering in on her high heels. "So, Vanya," she laughed, "this is Miss College Professor." The hooker looked her up and down and grinned at the camera. "She doesn't look like a teacher. She doesn't look like much of anything. But after this, she'll look like a porn star." She laughed and moved towards the bed. "Rita," Vanya said and he followed the action, "dis is Anya. Or she is Anya tonight. Anya was da name of my sister, a wery beautiful woman. You are going to make love to her. And din, you are going to fuck me." Rita's eyes widened, but she stood up as Anya approached. She turned and looked hesitantly towards the camera, but not at it. "Go ahead. Make love to dis woman." I was shocked to see Rita smile and nod as she moved forward. My wife had never shown any interest in being with another woman before, but she stepped eagerly forward and found Anya's lips. The two kissed long and passionately, and my cock twitched uncomfortably in the confines of my pants as I watched the two women make out. Anya was the first to touch, moving her hand up squeeze Rita's breast. Vanya was a decent cameraman, following the action and zooming in and out at all the right moments. Rita was slow to respond, but she started moaning under the touch and moved her own hands to Anya's ass and tit, squeezing both with a sudden zeal. The two women fumbled towards the bed until they bumped against it. Anya reached down and grabbed the bottom of Rita's dress and pulled it up over her head. I gasped as my wife stood before another woman completely naked. Rita shifted and started to cover herself with her hands, but Anya shook her head. They resumed their kiss, only this time Anya's hands roamed over Rita's bare skin. Her nipples were rock hard and she squirmed every time Anya touched them. Anya finally broke the kiss and pushed Rita back onto the bed before climbing on beside her. Positioning her on her back, the prostitute leaned over my wife and kissed and licked at her naked skin. She spent a long time sucking on Rita's small breasts, perhaps fascinated by the size difference of her own. Anya was smiling when she finally pulled off her blouse. Her large breasts swayed above Rita's face, and I watched in awe as she leaned up and grabbed her tits, guiding one of the nipples to her mouth. Anya allowed herself to be rolled over and Rita climbed on top. Any inhibitions she might have felt were gone and she licked and sucked at the other woman's tits and body, purring as she went. Anya helped her undo the skirt and push it passed her legs to the floor. Rita stared at the woman's bald cunt, uncertain as how to proceed. I had no choice. When Anya took charge again, sitting up and kissing my wife while four hands roamed naked skin, I had to release my hard cock before it burst through the fabric. They made out for long minutes before Anya deftly turned them into a 69 position. Rita moaned as Anya plunged her face right into my wife's cunt. I was hardly aware of my cock exploding, showering my shirt and legs with cum as the camera zoomed in on Anya eagerly eating out Rita. My wife twisted and moaned, and I saw her body shutter as an orgasm rocked through her at the woman's touch. Rita screamed incoherently as Anya continued to lap away, prolonging the orgasm as long as possible. The camera moved to the other end, and as Rita slowly came done from her orgasm, my wife looked up into the camera and smiled before lowering her face into a woman's cunt for the first time. The pair went at it for countless minutes, sucking and tasting and fingering each other to orgasm until Rita rolled off and lay on her back gasping. Anya slowly sat up, a lazy, contented smile on her lips and bent down to kiss Rita. My wife gently kissed her back, and Anya got up, gathered her clothes, and with a wink into the camera, left the room. The scene suddenly changed and the angle was different. It was a wide, stationary view of the entire bed, the camera set up on a tripod. My Rita was still naked on the bed, propped up on the pillows and grinning away from the camera. Only moments later, Vanya's naked body entered onto the screen, his massive cock jutting obscenely straight out from his body. Rita licked her lips and crawled forward to meet him at the edge of the bed. I marveled both at Vanya's size and my wife's eagerness to stuff his cock in her mouth. My soft cock twitched in my sticky hand and started to swell once again. I watched the wanton display in shock as Rita sucked hard on his cock, devouring over half its length before running her small mouth around the outside of his shaft and down to his balls. Vanya moaned and ran his hands through her hair. Even though she was over a dozen years his elder, Rita looked like a child next to his much larger, muscular form. I could clearly hear Rita's sucking and slurping as she enthusiastically swallowed another man's cock in front of a camera. "You make me cum," Vanya moan as he pushed Rita away. "But not yit. I cum inside you. You will beg now for Vanya's cock." Rita looked up at him uncertainly as he stood over her with his arms crossed. When she failed to answer, he grabbed her by the hair and pulled her screaming onto the floor. "I said beg," he snarled and brought an open palm down across one of her exposed tits. I know how sensitive Rita's nipples are when she's aroused, and was not surprised to hear her howl in pain. "Beg!" He slapped her other nipple even harder. "Please," she moaned. It was a forced plead, but I could hear the sincerity in her voice. Her entire body was flushed with desire, and I thought I could almost see the wetness glistening from her cunt as I stroked my now fully hard cock furiously. "Please fuck me, Vanya. Fuck me good." "I will," he laughed and dragged her forward, shoving her chest down onto the bed. He dropped down in behind her and lined his cock up with her cunt. From that angle, I could see almost nothing of my wife as his large frame completely covered her tiny one, but I heard her scream as his massive cock entered her cunt for the first time with one, massive shove. Vanya took a handful of her hair in one hand, and a firm grip on her hip with the other and pulled his himself back. With his next thrust, Rita scream turned from shock and pain to lust. "Yes," she howled as Vanya started pounded his large cock into her small, tight hole. "Yes, Vanya. Fuck me. Fuck me like a bitch. Fuck meee!" Her screams turned into incoherent babbles as she came around his cock. They set off my second orgasm, shooting more cum over myself. I hardly noticed. With her tight hole, feeling all the tighter by the girth of his cock, I was not surprised when Vanya pumped hard into her and came deep inside her pussy. Vanya slumped, sweating, on top of my wife. The lay panting together before Vanya finally climbed off of her and headed towards the camera. As he reached for it, the scene changed again. Vanya sat fully clothed once more front of the camera. "Yes," he said happily. "She was a good fuck. I will fuck her more, much, much more." He laughed and I slowly clicked the TV off. I stared blankly at the screen before grabbing a dishtowel to wipe myself off. Searching through Rita's study aids, I found Vanya's number scrawled across a piece of paper. Forcing my heart to slow and my nerves to relax, I dialed the number. Homework Experiment "Allo?" a thickly accented voice answered. I gritted my teeth to keep from exploding. "You son of a bitch," I snarled. There was a pause before Vanya started laughing in my ear. "What have you done to my wife." "Simple. I drug her?" I was stunned by his blatant honesty. "What?" "I drug her. I am chemist, after all. Prodigy, dey say, and dey are right. I feed yer weef mind control drug. She very happy now." "You drugged my wife, you mother fucker. I'm calling the police, you piece of shit." "I would not be so fast," he said calmly. "If she is questioned, she will say she wanted it all. The drug controls, but it also brings out her natural tendencies. She did not do anything she did not want to do. I have simply suggested that she forget everything we have done together… for now. If you press me, I will send out copies of that tape, and many more. She and you be ruined. And if you ever question her about it directly, she will remember every with so much guilt that she will run away forever." He laughed again, in a cocky youthful arrogance and hung up the phone. The next night that Vanya was due at our house, I made an excuse to be gone for the evening. My wife never once let on that anything was amiss. Vanya was right. The chemicals that he was feeding her left her without memory of what she was doing. But was he right about the other part, about her suppressed nature coming to the surface? I couldn't deal with it, or face Rita, and spent all of our together time trying to avoid her. And if that tape should ever get out, it would destroy her career, and probably our marriage. And did he have more? I thought about driving to the bar and drowning my thoughts, but there was no way that I was going to leave him alone with her, but I didn't want him to know that. I parked a block away and waited in my car for over an hour when Vanya finally arrived. I gave them several more minutes before sneaking down the street and quietly letting myself in the front door. I could hear their voices from the kitchen, but it was not the sound of a student and teacher. I crept inside and peeked around the corner. My eyes almost bulged out at the sight. Vanya was sitting on one of the kitchen chairs, naked, stroking his hard cock. My lovely wife was sitting across from him, equally naked. She was cooing at him as she sprayed whipped cream all over her chest. She giggled at the strange coolness before putting the can aside and rubbing the cream into her skin. Rita moaned and purred, closing her eyes as she slowly rubbed the whipped cream all over her tits and stomach. "It almost feels like your cum," she giggled and licked her fingers off. Vanya smiled and pointed to the large cucumber on the table. "Dat," he ordered and Rita happily picked up the large vegetable. In her hands, with her obvious intent, it was a grotesque phallic monstrosity. I watched, completely shocked, as Rita instantly rubbed the cucumber along her wet slit before aiming it at her cunthole. To my knowledge, she had never even had a dildo inside of her, but here she was easing the first few inches of a vegetable that put even Vanya's cock to shame right up into her. She closed her eyes again and smiled to herself as she readjusted her position and forced more of the cucumber inside. She winced in discomfort but steeled her grip and pushed even harder. For long moments, she held the cucumber deeply inside of her, allowing her cunt muscles to relax around the intrusion. Before long, she was slowly sliding it in out of her greased hole. Vanya watched happily as she fucked herself with the vegetable, now shiny with her juices, and stroked himself. Rita picked up the pace, squirming in the chair and trying to position herself to allow even deeper access. I could do nothing but watch, afraid of all of Vanya's warnings and threats, and intrigued by a side of Rita that I have never seen. Over and over, she fucked herself, moaning and squirming. The sloppy whipped creamed oozed and glistened over her chest. "Yes," she moaned, "oh fuck yes. Oh Vanya. Fuck. It's making me cum. I'm going to cum. Shit. Fuck." She babbled off into a high pitched scream that hurt my ears as her body rocked with an orgasm more ferocious than I have ever seen her experience. Puffing and sweating, she pulled the cucumber out of her and tossed it on the floor. "Fuck me, Vanya. Please, fuck me hard. I need to feel your cum in me." Vanya was on her in a flash. Pulling her to her feet, he mashed his body against hers and kissed her hard. The slick cream pressed into his hard body as he held her even tighter. He scooped his hands under her ass and picked her up. Carrying her to the counter, her set her ass on the very edge and wasted no time in lining his cock up as Rita spread her legs wide. Already well used, Vanya sunk deep into her cunt with one push. She moaned as Vanya groaned into her mouth. His fucking started hard and fast. Grabbing her by the shoulder, her smacked her face while riding her with ferocious thrusts. "Yes," he moaned. "You are a good slut. You fuck Vanya good." "Yes," she screamed as another orgasm ripped through. "Fuck me, Vanya. Use me like your whore." Vanya slapped her face again, harder, and then moved his hand to her tit. In the middle of her orgasm she could do nothing but howl and cum harder as his fingers dug into her tender flesh. Both his hands moved back to her ass, and his nails clawed at her soft skin as he pounded her tender cunt with all his strength. She shrieked again as another orgasm started right after the previous. Without warning, Vanya suddenly pulled out of her and yanked her off the counter. He shoved her roughly to the floor and I watched in awe as he jerked his shaft rapidly over my wife. His cock exploded in a white torrent that sprayed down over her shocked face. Rita quickly opened her mouth, catching as much as she could as the huge load covered her face, hair and chest. Vanya's knees buckled, and when he finally stopped cumming, Rita opened her eyes and looked straight into mine. There was no fear at being caught, or shock, or even guilt, just contentedness. Vanya turned and followed her gaze. Seeing me standing there, he started laughing. Torn between attacking the man who just fucked my wife and leaving, I wheeled around and quietly left the house as Rita scooped at Vanya's cum and greedily fed it to herself. That was the last time they met at our house for their tutoring. From then on, Rita left to meet at Vanya's apartment. She acted as if nothing was wrong, or as if she had no real memory of me watching Vanya cum all over her face. I felt sick inside, as much as I felt shamefully aroused. I dared not risk confronting her, in case Vanya's warning was true. She was acting like a little slut, but I didn't want her leave. Had I known what was to happen at Vanya's the first night she went there, I don't know if I would have begged him to make it all stop, or begged to allow me to stay and watch. Vanya had invited three of his classmates over, three young men who all knew my wife by sight, and lusted after her tight little body. It was the first night she would ever spend with more than one man. She entered his apartment dressed in the conservative pantsuit that she had worn during the day, books held in her arms. Her eyes widened in shock when she found Vanya and three other men stripped naked and waiting her. They were all about the same size and build, around six feet tall with six to seven inch cocks. They had the thin look of scientists-to-be, not the look of Vanya at all. She turned to flee, but the men rushed forward, eager and horny from Vanya's description of her sweet cunt and talented mouth. Vanya watched, laughing quietly as the men pulled her into the living room and threw her to the floor. A cock was thrust into her mouth before she could scream her protests while the other two worked quickly on her clothing, tearing her pants and sending buttons flying from her blouse. Once fully naked, they allowed her to stand so the men could inspect her body. She stood frozen in place her body only shaking slightly as the men walked around her, cupping and squeezing her small tits and tight ass, and running their fingers over her slit. She could feel herself getting wet at their touches despite her fear and uncertainty. Vanya kept back out sight, watching her reactions. Young and horny, the men wasted no more time and pushed her back onto her hands and knees. On them climbed in behind her and thrust his cock into her cunt. He was not slow, and he was not gentle, and Rita screamed at his penetration. The one that fed her his cock before took the opportunity to shove his cock back into her open mouth. She gagged and tried to spit his cock out, but could not back up with the man pressed up behind her, or turn her head with the man in front of her so close. While the man in the rear fucked her cunt hard, the man in the front held his cock in her mouth, but it was not until the third man kneeled down and started to roughly maul her tits and nipples that she responded. She allowed the situation to take its course and enjoy the virile young men as much as possible. Moaning, she started slurping on his cock, working it over to the best of her ability with the man behind her pounding away without mercy. Vanya watched the scene in his living room happily as the foursome rolled around into different positions. They took turns fucking her doggy-style and on top, letting her suck on their cocks or ride them enthusiastically. Her mouth got the first load, and she swallowed it all, but her cunt was not left out. Over and over, the young men fucked her, all of them cumming at least twice, one of them three times before finally rolling off of her exhausted. The men dressed, thanked Vanya, and made some small talk about one of their classes before leaving. Rita lay on the carpet, humming happily to herself. Her face and chest glistened with cum, and cum was oozing from her swollen pussy. "Dirty little slut," Vanya yelled as he stormed into the living room and grabbed her by the hair. Rita shrieked as he pulled her to her feet and dragged her into the bathroom. Throwing her into the shower stall, he turned on the faucet. Rita screamed even louder as the cold struck her sweaty body. He slapped her hands when she reached for the hot water tap. "You have been a wery naughty girl," Vanya snarled. "Wery naughty." Standing beside the stall, he forced her to scrub herself under the frigid water until she was crying, begging to be let out. Vanya grabbed her arm and pulled her out, sending her sprawling to the bathroom floor. He dove down on top of her, his large framed covering hers, and rammed his cock against her pussy lips. The cold water had stolen any lubrication she had inside her, but Vanya pushed harder, forcing his way into her resisting cunt. Rita shivered, her teeth chattering and failed to notice the pain as she clung to his body for warmth. Once he had a few inches inside, Vanya attacked her cunt with more force than any of the other students could. He fucked her brutally, her cunt quickly dampening with the large cock inside of her. She moaned and quivered as warmth returned to her body. "Yes Vanya," she screamed. "I am a dirty slut. Fuck me like a slut. Fuck me." Vanya pounded into her, bruising her ass on the hard floor as he pumped away for a quarter of an hour. His body was glistening with sweat when he finally tensed and pumped his hot cum deep inside her. She moaned and squirmed, thoroughly fucked, and happily satisfied. Rita's gradual transformation over the consecutive several weeks had at least one positive advantage. Our sex life, which was already healthy, erupted to frantic and numerous sessions whenever we were home together. She suddenly wanted to try new things that we never talked about before, and I was happy to oblige. But there was always the underlying reality that Vanya was still fucking my wife, sharing her with his friends and God knew who else, and she seemed only satisfied after being with him. One night, as we lay together in the dead hours after midnight, Rita was ready to go again. She poked and prodded at my body and flaccid cock, trying to find new life, begging for one more orgasm. It had started after dinner, when she sucked me off under the dining room table, swallowing all of my seed, before heading upstairs. For the next several hours we fucked liked teenagers in every position we could twist our bodies. I came for the forth time as Rita had climbed on top of me and coaxed the remaining semen from my balls with her wild riding. We held each other for several minutes before I started to doze off on the cum soaked sheets. She tried for another fifteen minutes to get me hard again, but it was not going to happen. Frustrated, she pushed away from me and rolled over. I must have just started to doze off when I heard Rita making a strange noise. I rubbed my eyes and pushed myself up on my elbow to find Rita on her back, her eyes closed, and one hand rubbing her tender tits. Her other hand was between her legs, firmly holding a bottle of water she kept on the nightstand. She was rubbing the white cap of the bottle on her swollen clit and eagerly moved it down her slit. She spread her legs wider and shifted her hips, allowing the bottle access to her cunt. I couldn't believe what I was seeing as I watched three-quarters of the bottle completely disappear inside of her. The rough cap and ridges on the bottle must have been causing her discomfort. She wrinkled her face and gritted her teeth. Nonetheless, she started fucking the bottle into her cunt. She was rough with herself, pounding her cunt with the rigidly hard bottle and mauling her tits. Already over-sensitized, Rita came quickly, screaming as she let go of the bottle to help grope her tits. She squeezed her legs shut in the throes of orgasm causing the bottle to squirt out and continued to writhe on the bed. When she was done, she didn't even look at me as she kicked the bottle to the floor and rolled over to go to sleep. For the remainder of week, things almost seemed to get back to normal. Rita still left on her appointed nights, but only was gone the necessary time to needed to complete a one-hour tutoring session. She also came home with no signs of being ravaged by Vanya. And, by the end of the week, our lovemaking was returning to just that. I was both strangely happy and bizarrely sad to see the wildness that my wife had been adopting suddenly disappear. That Saturday was my wife's nephew's birthday party. Tom was turning eighteen, and all the close family was there which made for a small party. Rita was the youngest of three children, having an older sister, Peggy, who was 38, and her older brother, Rick, who was Tom's father, was 43. The grandparents were also in attendance, as well as some cousins, and siblings, all much younger than Tom. I got along fairly well with her side of the family, and allowed myself to get involved with all the family activities. It was right before dinner that I lost sight of Rita. The party was being held at Rick's house. Rick had made a good living for himself and his family, and the size of his house showed it. Having not seen her for sometime, I went off in search of my wife in case she wasn't feeling well. I romped through house, eventually heading into the cool basement. It was a fully complete basement with a family room, game room and some spare bedrooms, but was rarely ever used. I took a quick peek around, and was about to head back upstairs when I heard Rita's voice coming from one of the spare bedrooms. I walked towards the dark room, and found as I got closer that the adjoining bathroom light was on. From the bedroom door, I could see clearly into the side bathroom. Rita was standing there, her arms wrapped around Rick. My eyes nearly bulged out of their sockets when my tiny wife got up on her tiptoes and kissed Rick on the lips. From the look in Rick's eyes, it was something he wasn't expecting either. "Come on, Rick," she cooed. "I do it real good." "No," Rick snapped, but did nothing to push Rita away. "I'm married. And, you're my sister for Christ's sake. What are you thinking?" "I'm thinking my big brother hasn't had any relief from a woman in a long time." Rick's eyes narrowed. "Come on, I know that Sally hasn't put out for you in over a year. Women talk, Rick. When was the last time you had a woman's lips around your cock. You have a sexy woman offering it to you now. You going to say no?" "I can't," Rick groaned, and tried to pull away. Out weighed by a hundred pounds, Rita somehow managed to hold him still. "I'll do it real good for you, Rick. I promise." Rick groaned again, but didn't try to pull away as Rita dropped to her knees in front of her brother. She fucked her student constantly. That was one thing. But now my wife was about to suck off her own brother. I couldn't believe this was happening. I wanted to barge in, to stop her from making this incestuous mistake. But all I could was watch, fascinated and horrified. Was this why things were getting back to normal, because Vanya was programming her to give her own brother head? Rick closed his eyes and did not open them until she was done. Maybe he was imaging it was his wife, or some other woman, anyone but his sister who was undoing his pants. She pulled them down to his ankles, and pulled his underwear down with them. I watched Rita lick her lips as she cupped her brother's balls in one hand and stroked his rapidly hardening cock with the other. He was not quite fully erect when Rita opened wide and plunged her mouth onto him. She sucked hard and pulled her mouth back off the instantly hard shaft. Smiling, she looked up into her brother's closed eyes and plunged down again. She obviously thought she was safe as she slurped and sucked with a total disregard for the noise she made. Her enthusiasm for her brother's cock could only have been preprogrammed as her head bobbed wildly up and down the shaft. Rita was probably right about her brother's lack of sex, as the older man held one for less than two minutes under her workout. As Rick's legs started to buckle and the first wad of cum shot into Rita's mouth, I heard Sally's voice calling from outside; dinner was ready. I waited long enough to see Rita suck every drop of cum from her brother's balls and swallow it all before I quickly made my way back up the stairs. Dinner was held in back yard on their picnic tables to accommodate all the people. It was also more of a late lunch, as Tom had plans to celebrate that night with friends. All through the meal, I watch Rita and her brother. Rick shifted nervously every time Rita got too close, and even jumped when she accidentally brushed his arm. Rita acted as if nothing had happened. It was just another normal, family function for her. It was only because I was watching so closely that I noticed Rita pull Tom aside and whisper something in his ear. Tom looked at her suspiciously, but nodded and sneaked quickly around the side of the house while Rita headed inside. I waited long enough to not look suspicious and followed after my wife. I entered the back door just in time to see Tom come through the front and Rita lead her nephew into the basement. She couldn't be? I followed them at a safe and quiet distance and Rita lead Tom to the same bedroom, but they stopped there, beside the bed. "So," Tom asked confused, "what's going on, Aunt Rita?" "I have a present for you, Tom," Rita purred, making Tom look around nervously. "And I thought it better I give it to you in private." She slowly walked towards him. "Are you a virgin, Tommy?" "Aunt Rita?!" "Answer the question." "I-I am," he mumbled after some thought. Homework Experiment "Perfect," she said. To Tom's surprise and my suspicion, Rita scooped the straps of her summer dress off her shoulders and let it drop to the floor. Tom's eyes widened as he stared at his aunt dressed in his bra and panties. "Aunt Rita?!" "I saw the way you looked at me today, looking at my body. I know you were checking out my ass when I bent over, wondering what my tits looked like." She reached around and unsnapped her bra and tossed it away. Without a pause, she dropped her panties and kicked them away, standing completely naked in front of her brother's son. "Happy eighteenth birthday, Tommy. I'm going to make you a man today." She moved forward and kissed him in the same way she had kissed his father less then two hours before. Tom hesitated a moment as his aunt kissed him. It was true, he was checking her out. She was hot for an aunt, but he had never dreamed it would ever go this far. Finally, his teenaged hormones took control and he kissed her back. She took his hand and led him to the bed. Smiling, she climbed on and lay on her back, looking up at him. She glanced at the clock at the bedside. "For the next twenty minutes, you can do whatever you want with me. Then we have to get back." At least she still had some reason. I wasn't even going go through the false pretense of thinking of stopping them. In a way, I was happy for Tom. He was going to be made a man, an Rita was one hell of a way to make it happen. Tom looked at the clock, then back at my wife lying there before him. He had all of his clothes off in record time and jumped onto the bed. The first thing he did was what any horny teen male would likely do; he went for her tits. His hands were all over her body as he kissed and sucked and bit her small, firm tits. Rita moaned, whispering his name and encouragement, as his eager young hands were all over her. I was surprised when he moved down and put his head between his legs. It wasn't something I would have thought a young man interested in, but he plunged his face right into his aunt's juicy cunt. Rita moaned loudly, gibbering incoherently as Tom licked and slobbered all over her cunt. He has no obvious skill in cunnilingus, but it didn't matter to Rita. What he lacked in style, he more than made up for in enthusiasm and desire. When he trust two fingers into her cunt, Rita started screaming. Either frightened by Rita's sudden and powerful orgasm, or scared of her screams being heard, Tom stopped and climbed in top of her. He kissed her still screaming mouth, and Rita kissed him back, licking her juices from his face. The two rocked together in a tangled mess of limbs before Tom's hard cock finally poked into Rita's wet hole. It slipped inside easily, and Tom started pumping with all he was worth the moment he felt her hot, wet cunt suck onto his cock. Almost immediately Rita started cumming again, and Tom covered her mouth with his own to muffle her cries. The young man continued to pump away, but his hard, virgin cock did not hold up long under the excitement of Rita's spasming cunt. I could hear his groans over her cries as he shot his very first load into a woman's pussy. They lay together panting for sometime, and when they finally broke, only fifteen minutes had passed. Rita pushed her nephew down on his back and started to clean him off. When his cock started to harden, she took into her mouth and sucked eagerly. His second load lasted only slightly longer than his first, before he groaned and pumped cum into Rita's mouth. She sucked it all in, and swallowed every drop just as his mother started calling his name to cut he cake. The two parted, and Tom frantically got dressed. Before he raced out of the room, he gave my wife a quick kiss on the cheek. "Thanks, Aunt Rita. That was the best present ever." Vanya left the school at the end of the semester for an ever better deal. Over the remaining few weeks, he continued to take his liberties on my wife who retained no real memory of his actions. But the effect of his drug never really left her system. Our sex remained as wild as she could make it, and her inhibitions were forever destroyed. More than once, I caught her with her brother and nephew, the mailman, and even a saleswoman. Although Rita never spoke of him again, I will never forget Vanya and the bittersweet change he brought to our lives.
