Molesting my little sister An Erotic Story This all started when Mom asked me if I was molesting my little sister. A truly unfair accusation. Well ... Actually, it started a few hours earlier than that, as this story will tell: I groaned as the last weak spurt of cum left my penis to trickle into the tight little slit of my big sister. Although she's been fucking for almost three years longer than I have, Melissa is still so tight she can almost squeeze all the blood out of my penis and leave it soft; especially considering the extra strong contractions her vagina makes around my prick when she cums with me in her already tight little tunnel. Not that my big sister would ever leave me hard, once I had slid my swollen prick inside her. My sister knows better than to cheat me like that ... just like I know better than to cheat her by not filling her sexy tummy full of thick white baby-juice at least once a day. I wouldn't like to be sexually neglected like that ... So I try to make sure neither of my sisters are either sexually abused OR neglected by me. Besides, it feels GOOD to squirt my cum inside my big sister ... Yes, even better than down her throat or up her ass. Knowing Melissa has been trying to get pregnant for over six months now just adds to the stimulation of fucking my own sexy sister and filling her tummy with incestuous seed. There's even a pretty good chance that if Melissa DOES have a baby, the kid will be mine ... since Dad doesn't fuck her more than about twice a week, and her current boyfriend doesn't manage to see her even that often. So, it's mainly up to me to see that my big sister's womb is properly filled with virile sperm wriggling up inside her belly, seeking her ripening eggs. I don't mind. As I said, it's fun to fuck my sister, cum inside her, and (hopefully) even get my sexy big sister pregnant with my baby. Lately, I've been managing to fill my sister's tummy with cum at least twice a day ... Which is pretty good, considering .... All of which makes my mother's accusation even that much more unfair. "Michael?" asked Mom. "Did you remember to fuck your sister this morning?" This while I was defenselessly eating breakfast. "Mom!" I objected; choking on a piece of toast, and blushing red to be asked that sort of question in front of the whole family. Dad just grinned; and Sandy gave me that look that only sexy little sisters can give. Melissa however, came to my defense. "Mom," she objected, "that's not fair. Mike fucked me twice last night; and from the feel of it must have left at least three or four pints of cum inside me. I'll be leaking for a week after I get back to school." "Well," my mother replied, mollified, "I just want to make sure he didn't neglect you. After all, you'll be going back to college next week, so your brother only has a few days to get you pregnant. I don't want you two kids to miss any chances." 1 "Yes, Mom." Melissa's sigh echoed my own. My sister's glance met mine; and her grin seemed to show she was thinking the same thing I was: 'Mothers.' "It's just that since you've been fucking the twins next door, I didn't want you to forget your big sister," she explained. I wondered when Mom had found out about THAT. Still, Mom usually DOES find out about us kids and who we fuck. Not content with accusing me once, Mom continued, "And don't forget to molest your little sister, too." "Mom!" I objected again. "She's just a little girl." "I didn't SAY you had to fuck her," my mother responded. "Just because Sandy is too little to fuck, doesn't mean you can't feel her up, get her to suck you off, finger her off, or even squirt your sperm inside her cunny. You don't have to fit your prick right up inside your sister to cum in her, you know. There's lots of ways besides fucking a girl to get your sperm inside her vagina. Not only holding your prick up against the girl when you cum; but even jacking-off on her tummy and taking your finger and putting it inside her ... not that I'd really expect a virile young boy your age to be jacking-off, especially when you have two healthy sisters to squirt your sperm inside." "Yes, Mom ... I KNOW that," I sighed. I didn't tell her about Ginny next door. If my mother found out that I'd not only been fucking the twins, but their six-year-old little sister as well ... Well, better not. That MY little sister Sandy was almost a year older than the child, would just make Mom that much more insistent. Besides, I had NOT been neglecting Sandy. The cute little twerp probably had been getting almost as much of my thick white cum in her tummy (both squirted in pearly-white jets up right inside her cute little cunny, and down her hardworking little throat) as our big sister had. As you can tell, I *like* sex ... even (or especially) with my own sisters. Family sex is what you always come back to ... girlfriends and cute nympho- twins next-door just aren't always available, while your mother and sisters are. Well ... (I was reminded of Melissa heading back to college) Almost always. Hopefully, my big sister would have a big tummy to remember me by, while she studied. I knew she was as excited by the idea as I was. Still, there's something to be said about twins too. Especially cute, sexy, and horny twins, like the Morgan sisters. (Not to mention THEIR little sister.) Feeling my prick spasm their tight little slits full of thick white baby-juice was something I was looking forward to doing two or three times that day. Yes, at fifteen, I *can* go that often ... and sometimes even more than that, as Colleen had found out when she caught me pulling out of Candy, while Sandy was lying there beside us with cum welling out of her tight little hole. Before I knew it, both girls had their little sister on the bed ... and I was sliding into the tightest, sweetest little hole on the planet. 2 Colleen didn't object though ... and before I knew it, I had filled the six-year-old's tight little baby-hole full of enough sperm to keep the kid knocked up for the next ten years ... IF little girls her age could get pregnant ... which thankfully she was probably too young for, unlike the two horny giggling ten- year-olds watching me try to plant a baby in their baby sister's cute little belly, by sticking my swollen baby-maker up in the kid's tight little slit and pumping her baby-hole full of thick white cum that was teeming with my potent seed ... just like I had already filled both of her big sisters' holes full of sperm a few minutes earlier. I could hardly wait until this afternoon, when we planned another get-together ... this time, intentionally with all three of us. I might die from sexual overexertion; but I would die happy. Still, remembering how horny *I* had been, even when four or five years old, I wasn't about to neglect Sandy, either. Thus about an hour later found me with my hands up underneath my little sister's skirt, while my pants were in a heap on the floor, and the little seven-year-old had a death-grip around my swollen penis. Feeling the child's budding little titties (Yes, my little sister HAD started developing titties ... not MUCH of course, but some.) and flat little tummy did almost as much to make my prick as hard as a rock, as the cute kid's manual attention to the swollen member had. Sandy is pretty good at jacking me off (and sucking me off, and even (starting a couple of months ago) taking my prick up the ass (with LOTS of KY jelly). So good in fact, that I was almost ready to cum within a couple of minutes after we really got into it. "Uh, Sandy," I mumbled; removing my mouth from my little sister's, so I could talk instead of licking her tonsils, "I'm gonna cum, pretty quick." "Mmmmm," she grinned back at me. "Do it in here," she replied; fisting my prick, and directing the head against her puffy slick mound. "I know about you and Colleen," she informed me; rubbing the pre-cum slick head around the opening to her vagina, and then spreading her legs until she was almost doing the splits. "And she's almost a year and a half younger than I am," Sandy reminded me in an accusing tone ... as if I had been neglecting her by not taking her virginity ... something that I hadn't done since the little girl first slid into my bed about two years ago; the child wanting some of the same pleasures her big sister got from me. I just didn't want to hurt the kid. Somebody else had (obviously) long since taken Colleen's virginity, or I never would have fucked her like I did her big sisters. "Oh, God, I can't ...," I groaned. Only by the time I had finished objecting, I could-have ... and had. There was a sudden snapping sensation, and almost immediately the head of my prick had vanished into my seven year old sister's tight little baby- hole; leaking sperm and pre-cum into the child's defenseless belly. 3 I could feel Sandy's virginity stretched almost to the breaking-point, while the tight ring of her opening squeezed my prick in an embrace that would have to be felt to be believed. Colleen next door (it seems) does NOT have the tightest, sweetest, and sexiest little cunny in the world, after all. I couldn't help it. For the first time I filled my little sister's tight little tummy full of incestuous cum from the INSIDE, instead of squirting it into or onto her from the outside; spraying the child's womb full of thick gooey cum just swarming with millions upon millions of my sperm. God, did that feel good. Squirt after squirt, jet after pearly white jet of incestuous cum filled with teeming sperm spat into my little sister's unprotected belly where it belonged ... without condoms, pills, or (barely) even her soon-to-be-missing virginity to get in the way; as my penis belched spasm after spasm of gooey white pregnancy-juice into the little girl's tight little tunnel, right THROUGH the torn hole in the center of my sister's hymen, as if I was trying to impregnate the kid with my baby right then ... in spite of her age. And, in a way, I guess you could say I was. Both of us knew it was improbable to the point of almost impossible; but that didn't keep us from enjoying the thought anyway. Pregnant little girls are a horny subject often discussed around our house. No, not likely ... but not *completely* impossible, either. Still, we both felt fairly safe ... which made the idea of me planting a baby in my own sexy seven year old little sister's cute little tummy even that much more erotic. The idea of a second (or even first) grader with a swollen tummy was often responsible for some of the wilder activities in our family. It was now WAY past too late for Melissa, and almost too late for Sandy ... but that didn't keep us from trying anyway. No way was either Dad or I going to neglect my little sister by not letting her at least TRY. "Thanks, Big Brother," she sighed; snuggling her still heaving belly even closer to mine. Only the fact that I was now wilting from cumming inside her, kept my prick from completing the job of taking my little sister's virginity right then. We snuggled closely together for a moment; enjoying the last twinges of after-sex intimacy. Sometimes I think Sandy enjoys sex even more than I do ... if possible. On the other hand, it might be that the little girl just doesn't have as many sex-partners as me ... My sister only having Dad and me to satisfy her sexually. Knowing that once I had gotten the head of my prick inside the little girl's body, the rest would fit whenever we decided to try, both Sandy and I were happy with the information that in the very near future ALL of my prick would be inside my little sister's slick little tunnel where it belonged, the next time I filled the kid's vagina with incestuous cum; pumping my cute little sister's sexy young tummy full of her own big brother's potent seed properly ... the way a boy is SUPPOSED to fuck his sister ... with thick white jets of my sperm bathing the child's uterus; forming a pool of pearly-white goo next to my sister's cervix and soaking into her developing young womb where it belongs ... instead of both of us being slightly frustrated by my spilling my cum onto (or into) her belly as if Sandy was still just a little girl. 4 Sandy may be too young too get pregnant yet (like our big sister Melissa, or even the twins next door), but since the second-grader is finally able to take my sperm right up inside her sexy young tummy the proper way ... with her own big brother's swollen penis jerking, spasming, and pumping thick heavy gobs of incestuous baby-goo directly into the child's vagina; squirting sticky white jets of potent family seed against my little sister's cervix and into the pre-teenaged girl's developing young womb ... just like a girl is supposed to be fucked by her brother, Sandy is definitely no longer just a "little girl" any more, but a nubile young woman. Thank goodness I can finally stop just molesting my little sister, and start treating her like a sister SHOULD be treated by her big brother. Both of my parents (but Dad especially) will be glad to learn I'm not molesting Sandy any more. 5
