obviously teaching my big sister something, when I interrupted. I could see what my mother meant by "too big." I hadn't really noticed before, but Karen was getting fat. Not greasy, blubbery fat, but big in the breasts, belly, and butt. Especially in the stomach part. Now that I looked at her naked, for the first time in a couple of months, I wondered how I could have missed it before. My sister's belly was no longer the flat, smooth little tummy like mine, that she used to have, but it stuck out in front of her, a good 9 inches. When she leaned over, like she was now, as Daddy lay on his back, and my sister was leaning over him sucking on our father's cock, her belly seemed to stick out even more. Strangely enough, my sister didn't look unhealthy with all that fat. In fact, she looked healthier than ever, with a warm creamy glow to her skin that almost made me jealous.
I suddenly realized that I had barged in on something private. "I'm sorry," I squeaked, embarrassedly. "I'll come back later." "It's OK, Tammy." My mother's words stopped me. "It's about time, you learned about these things anyway. Especially, as your sister is getting too big, to take care of your father. I think it's time you learned how to fuck. Your sister wasn't all that much older, when your father taught her." "Fuck, Mommy?" I asked. "Uhuh," she replied. "Why don't you start by taking your pajamas off, so your father can show you what to do." I had always been a fairly obedient daughter; so I saw no reason not to do what my mother told me to. I stripped off the top, and shinnied out of the bottoms, as the rest of the family watched. Karen didn't say anything, but kept on slowly sucking on Daddy, while she watched me undress."You can stop now, Karen," said Daddy. "It's time your sister learned how, just like you did, and I don't want to waste it."
Reluctantly, it seemed to me, my big sister stopped her administrations on my father's cock.
However, when she pulled off, she did so with one long drawn out suck that seemed to last forever.
"Karen!" said Daddy.
"Sorry, Daddy," said Karen, "I just couldn't resist."
She gave Daddy a big grin, then turned it on me, to show that she wasn't mad at me for taking over her spot.
Daddy instructed me to lie back on the bed, and lift my knees. Shortly, I looked down and watched my father crawl between my legs, with his big cock dripping a clear white liquid.
"What are you going to do, Daddy?" I asked, a little scared. "Daddy's going to put his penis up inside your vagina," replied my mother. Daddy didn't seem like he could talk at the moment. "Once Daddy's penis is all the way inside you, You're supposed to squeeze on it, until he squirts his cum inside you. Do you think you can do that?"
"I don't know, Momma," I replied. "I suppose I can try. How do I squeeze, and what's 'cum' and how will I know, when Daddy squirts it inside me?"
My sister grinned, and opened her mouth to say something, when Momma glared at her, and she shut it with a snap. "Cum," said Momma, "is a sticky white liquid that men squirt out of the end of their penises. It's supposed to go up inside a woman's vagina, so that the man's sperm can impregnate the woman. You squeeze on your father's cock, by clenching the muscles in your vagina, just like you were trying to keep from peeing. Sometimes, you can feel it when a man 'cums' inside you, and sometimes not. Daddy'll tell you, when to stop."
"OK, Momma," I said, "I'll try." I was confused with all these new terms. Penis, and Vagina, I was familiar with, but first 'cum,' and Daddy squirting his "sperm?" inside my vagina? And Daddy's "sperm?" "impregnating?" me? I resolved to find out what all these new words meant. At least, I had figured out what one word, that I had wondered about before, meant. I used the word that finally made sense to me. "Come here, Daddy, and 'fuck' me," I said. So that's what the word "fuck" meant. I had always wondered.
My Daddy did just that. Hearing me asking him to fuck me, must have been exciting, especially, after hearing my mother tell me how to do it. Daddy rubbed the slippery head of his big cock up and down in my little crack. "Oooh Daddy," I said, "that feels good." It did, too.
"If you think that's good, just wait until he 'cums' inside you," said my sister with a grin.My mother glared at Karen again, and she shut up.
"Ungh, Tammy," said Daddy, "here it comes!"
I wondered what he meant. I hadn't felt him get inside me yet, was he squirting his 'cum,' already? All of a sudden, I realized what he was talking about, as the head of Daddy's cock spread the lips of my tiny crack, and started to go up inside it.
"Oh my gosh!" I gasped, eyes popping. "It's going inside!"
"Oooooh," breathed Daddy. "It sure is!"
We both looked down, at where my father's penis had penetrated about 2 inches into my body. I felt stuffed, and yet three-quarters of my daddy's cock was still waiting to get inside me. "Oh Daddy," I groaned, as my father slid his cock out about a half inch, to lubricate it a little, then back inside another inch, "it'll never fit! It's too big!"
"Easy Tammy," said Daddy. "It'll go. Just relax, and let me get it in." All the while, he was working his cock in and out, gaining between a quarter, and a half an inch, at each stroke.
I gasped, feeling more and more stuffed, until suddenly it hurt. "OW!" I said. "That hurts!"
"Just for a minute," said Daddy, not relenting. "Just relax. I've got to break your cherry."
"Does he have to Momma?" I asked. Looking over at my mother, who was watching closely, for sympathy. Momma looked at me seriously, and nodded.
"You've got to do it sometime, Honey," she said. "It's best, if you let your father do it."
"OK, If I have to," I said, gritting my teeth. "Do it Daddy."
Daddy did. I let out a howl of pain, as Daddy's cock suddenly slipped almost all the way up inside my hole. This is the fun-thing called fucking, that all the kids want to do? I thought. They must be crazy!
"Easy Tammy, easy," repeated my father. "That was it. It won't ever hurt like this, after the first time. Next time, you'll really like it. I wondered what he was babbling about. It still hurt! Next time? I resolved, that after this, there would be no "next time." If Karen liked to be fucked, then SHE could fuck Daddy. Not me! I resolved to let Daddy finish, so I could show I wasn't "chicken," but this was it. No more fucking for me.
"Go ahead," I grunted, "fuck me." I figured that the sooner I got this over with, the better.
Daddy smiled down at me, taking some of the sting out of my disgruntlement. "OK Tammy," he said. "You'll like it a lot better next time."
Huh, I thought. That wouldn't be hard, since I don't like it this time, at all! Still, I kept my thoughts to myself, and started trying to squeeze on Daddy's cock, like Momma had told me to. I must have done something right, because Daddy choked, and said, "Ughn. Not so hard, Tammy. You'll have me cumming, before you're ready, yourself."
I didn't know what he was talking about, since I had given up on liking sex. Still, it was kind of nice to make Daddy feel good, even if I didn't. I squeezed him again.
"Argh!" Daddy groaned, then panted, as he struggled to hold back. This was kind of fun. I wondered just how long Daddy could hold out, so I squeezed him again This time, Daddy seemed to be expecting it, and he slid his cock out, when I started squeezing. My vagina must have stripped a lot of lubricating fluid from the end of Daddy's penis, because I was a lot slicker inside when I stopped squeezing, and Daddy pushed his cock back up inside me.
This time, Daddy's penis went all the way home in my belly. It didn't really hurt any more; I just felt stuffed like a turkey, as Daddy's cock butted up against my uterus, and started leaking sticky drops of pre-cum into the neck of my womb. Mmmm, I thought. You know, this could be fun after all. I squeezed on Daddy's cock again. This time, it excited me, almost as much as Daddy, as I could feel the warm pulsing of his cock inside my belly, when I squeezed down on it. It seemed to tickle me a little inside, and I felt like I wanted to scratch an itch.
"Am I doing it right, Daddy?" I asked, trying to pull daddy's cock up inside me, with just my inner muscles. This seemed to sooth the "itch" a little, as my vagina clamped down on my father's swelling cock.
"Oh Honey, Don't! I. . ." said Daddy, then his voice choked off, and his eyes grew big. "OH God, Tammy," he finally gasped, "I. . . I'm. . . "
Suddenly, I felt slicker inside, as Daddy's penis pulsed, and a warm dollop of slippery liquid splashed up against my womb.
The tickling sensation that I had just started to notice, as I squeezed Daddy's cock suddenly grew too big to ignore. It was like an itch, that I just had to scratch.
"Ung Daddy," I said, suddenly squeezing even harder; only this time, I had no control over it. "Daddy, Ungh, Do it. Unh, Uggnh, UUnghh!" I couldn't believe how good it felt. I had been intending just to make Daddy 'cum' inside me, when a ripple of sensations spread down my belly, centered in my little cunt; and suddenly nothing else in the world mattered, except Daddy, my cunt, and Daddy's wonderful cock, that was making me feel so good, as it pulsed time after time, filling my little vagina with squirt after thick sticky squirt of soothing warm liquid.
I was vaguely aware of Daddy's hoarse grunts, as he spasmed inside me, and my mother and sister nearby.
"Do it," said Momma. "Squirt your cum in our daughter. Let me see you get our little girl pregnant!"
"Yeah, Daddy," agreed my older sister, "knock the kid up, just like you did me I wasn't sure what they meant, but if it was what Daddy was doing to me, I wanted more of it. "Do it Daddy," I repeated their words, even if I wasn't quite sure of their meaning.
"Knock me up. Squirt your cum up inside me, and get me pregnant, like Momma says." Hearing his own little 10 year old daughter begging him to impregnate her, must have been a dream 'cum' true for Daddy. (Pun intended.) Daddy had started to slow down, as the slick feeling of his cum inside me soothed his cock, and reduced the tickling sensations. Hearing me asking him to "Knock me up," was a thrill that a man like Daddy couldn't ignore. Daddy's penis suddenly seemed even bigger, as he jammed it up inside me hard!
There was a sickening stretching sensation, as Daddy's cock stretched the entrance to my uterus, and suddenly Daddy was spewing his thick sticky cum right into my womb. I thought, that I had been excited before. When Daddy started squirting his cum inside my womb, it was as though I'd been kicked in the belly. I gasped, groaned, and shuddered, as the first real orgasm of my young life, caused me to flop and jerk on the bed, like a fish out of water. I choked, and gasped, and tried to stop, but the feeling of Daddy's sperm tickling the inside of my womb was too much. On and on it went, until Daddy's mighty spasms slowed, and my father finally stopped pumping his thick greasy cum into my belly.
"Oh Daddy, Daddy I. . . ." I couldn't say, how good I felt. Daddy slowly pulled his big cock out of me. I felt as though he was dragging my guts out with him, I felt so empty, afterwards.
"Mmmmlpfhh," mumbled Karen, as she swallowed Daddy's cock again. My sister must like the flavor of cum, because she didn't stop sucking, until every last drop of Daddy's sperm had vanished, and even the slightly red ring of sticky stuff left my now-missing maidenhead had been licked off. I was distracted from watching Karen cleaning our father's cock, by more sensations centering around the outside of my vagina this time. My mother, was cleaning me up, by licking up the juices running out of my little hole, just like Karen was licking on Daddy!
"Oh Momma," I said, "you don't have to do that!"
"Mmmmpf," said my mother, pausing in her cleanup. "It's OK, Honey, I like the taste of it." She didn't stop, until every trace of pinkish-white had vanished.
"I like it too," said Karen, as she finished cleaning my father's now limp cock with her tongue. "I don't often get 'cherry' flavoring."
The whole room burst into laughter, at my sister's pun. Even I smiled dutifully, as I vaguely remembered something Daddy had said about 'popping my 'cherry.' Afterwards, Daddy explained to me what "sperm" meant, and what they had meant by "get pregnant." I told my parents, that I didn't mind if Daddy "got me pregnant," but it was several years before he succeeded.
Daddy also apologized for not taking the time to do it properly. He explained that he had been so excited, that he had to do it fast, or he would have lost control, this first time. At that time, I didn't care, as it had certainly felt good enough to me.
The next day, Daddy showed me what I had missed the first time. He spent almost an hour working me up, and getting me excited, until I was almost pleading with him to fuck me, so that I could get off. Then Daddy fucked me for what seemed like an hour, but must have been only about 10 minutes, before he filled my belly with his white greasy sperm. By that time, I must have had about 5 or 6 orgasms in a row. Feeling my own father's thick baby-making cum filling my womb, was just icing on the cake.
