My mother is a pervert. I mean, what else would you call a woman who had her own son "Practice making a baby," in his little sister.

Yeah, that's what Momma did. Even now, I find it hard to believe she came up with that line. (Actually, when I asked her, Momma told me that she got it from a sex-story she downloaded off a BBS, when she was in college.)

I sure didn't know any better. Heck, I was only 6 years old at the time. Even Billy assumed that Momma knew what she was doing. He may have been 5 years older than I was, but he was still only 11 years old himself. (Actually Momma KNEW what she was doing all right. WE didn't know though.)

It all started one night, when I was getting ready for bed. She came into my room, dragging my older brother by the arm. Except for a pair of socks, Billy was as naked as I was. I was embarrassed, at being caught undressed, and I was about to object.

Momma never gave me a chance. She started in on Billy, like she was disgusted at something he had done. If I was embarrassed, my 11-year-old brother was mortified. Not only at being dragged naked into his little sister's bedroom. I could tell that something else was bothering him as well.

As I said, Momma didn't give either of us a chance to object to the other seeing us naked. In fact, it soon became clear that it was intentional.

"Now," said Momma, disgustedly to my big brother, "if you're old enough to jack-off, you're old enough to do it right! It's time you learned how to make a baby. Since Gina is only 3 years old, Diane's the only girl in the house old enough to help. You'll have to use her to practice with.

"Huh?" I'm not sure if it was me, or my older brother who said this. We both weren't too sure what our mother meant. Maybe we both said it.

Momma looked annoyed again, but explained, "It's time that Billy here, learned how to make a baby, so I'm going to teach him how to make a baby in you."

I was astonished, to say the least. Billy was just looking at Momma, with his mouth gaping open. If I was astonished, Billy was speechless.

"You mean I'm going to have a baby?" I asked. I knew a little about sex, but not much. I knew, for instance, that men and women did something together in bed, then a woman "got pregnant." (Her tummy got big, like my cousin June.) Then she had a baby. I had watched several relatives (including Momma) go through this process. At the time, I thought that only married people could do it.

"But Momma," I said, "I don't want to get married. At least not to Billy, anyway. Don't you have to be married, to have a baby?"

Billy gave me a look that told me that he didn't want to marry me, any more than I did him. It's not that we didn't like each other, we did. It's just that Billy was my BROTHER, for Christ's sake! I mean, Ick! I loved the big lunk, but MARRY him? No way! Of course, you've got to remember I was still a little girl, and didn't realize what a hunk my big brother was going to turn out to be.

Momma didn't do anything to dispel our preconceptions.

"I didn't say he was going to make a baby in you," she said. "I said, 'He is going to learn HOW to make a baby in you.' That means he's going to practice. You're too young to worry about having a baby anyway. Later, when you get older, you can get married and have as many babies as you want. In the meantime, Billy can practice making a baby in you, until he gets it right."

"OK, Momma," I said. If she figured that Billy really needed to learn how to make a baby, then I guess I was willing to help. I figured that I might learn something about how to make a baby myself. I was right, I did.

Once Momma saw that we weren't going to raise any more objections, (And after all, why should we? I mean she was our MOTHER. We trusted her.) she started right in on her instructions. "For a man to make a baby in a woman (or in your case Diane, ... in a little girl,) he's supposed to ejaculate his sperm inside her vagina, so that she can get pregnant.

"What's sperm Momma," I asked. Momma answered as if Billy had asked. (Well, after all, it was my big brother who was supposed to be learning how to make a baby.) "Sperm is little tiny things like tadpoles, that you have in your cum."

Billy blushed, when she said this, so Momma explained.

"Cum is the white stuff that came out of your penis, when you were jacking-off earlier."

Billy blushed even redder, if possible.

"You were really supposed to squirt that stuff inside Diane, so your sister could get pregnant," Momma continued," You weren't supposed to waste it all over your hands, or the bedspread."

"I'm sorry Momma, I didn't know," Billy apologized.

"Momma looked at him sternly for a minute, then softened. "I suppose," she said. "Anyway, you should be apologizing to your little sister, not me. After all, she's the one who got cheated."

"Cheated Momma?" I asked. I sure didn't FEEL cheated. I wondered what she meant.

"Of taking a mans's sperm. Girls should get as much of a man's sperm as they can get," she explained. "You are a little young yet, but Billy could at least have cum in your mouth, or up your ass, if he had thought to ask you."

"In my MOUTH?" I thought. "In my ASS?" Momma seemed to think Billy was cheating me, because he didn't volunteer to squirt his "white-stuff" in my mouth? Heck, I would probably have screamed at the very thought; if my big brother had approached me with such an obscene suggestion. I thought about it, and then realized that I had been lucky.

If Billy had done what he was supposed to, then it would have been ME who got into trouble, when I objected to him doing what he was supposed to. I shivered at my lucky escape. I decided that I'd better be ready, so that if Billy come around later and asked me if I wanted to swallow his "white stuff," I wouldn't be surprised. Heck, I might even like it, as Momma seemed to think I would.

"It's OK Momma," I said, "I don't mind."

Momma looked at me for a moment, then seemed to decide something. "Well, if you say so," she said. "Anyway Billy, next time you want to cum, you ask your little sister to suck you off, or better yet, to fuck you. After all, you're supposed to practice making a baby in her."

"Fuck, Momma?" I asked. I had heard the word before, but wasn't' sure what it meant. Billy looked a little confused too. I think he knew what it meant, unlike me, but didn't really believe that Momma wanted him to actually fuck his own little sister. Momma did.

"Fuck," she said, "you know, where Billy puts his cock up inside your vagina, and squirts his cum in you. What do you think we've been talking about?"

"Oh," I said, finally understanding. Billy was ... Omigosh! Billy was supposed to stick his "thing" up inside my crack, and squirt the stuff that made babies in there! No wonder a woman got a big tummy when she was going to have a baby! The man really DID make a baby inside her! Wow! I was astounded by this revelation. And I got to practice doing this with my big brother, just as often as I wanted to!

I thought a minute, then calmed down. No, Momma hadn't said that. She said that BILLY was supposed to "practice" making a baby in me, as often as HE needed to. Not quite the same thing. Still, I would probably get to fuck him a few times anyway. I hoped my big brother didn't learn too fast, before I learned all I wanted to.

Billy and I just looked at each other, until Momma got impatient. "Well," she said, "what are you two waiting for?"

Billy and I both jerked out of our trances, as Momma continued. "Since you both don't seem to know what to do," she sighed, "I guess I'll just have to teach you." Momma motioned to me to get on the bed.

"Now," she said, "Diane, you lie there on your back, and spread your legs. Billy, you get between your sister's legs, and put your cock up inside her." Momma watched closely, as we moved to comply.

"Now Diane," she told me, "It's going to hurt a little, the first time Billy puts his cock in you. This is normal, so don't worry. After the first time or two, it won't hurt at all, so you'll be able to feel your brother's sperm inside you without having to worry about it hurting."

"There's a little piece of skin inside your vagina," she explained, "it's called your "hymen," and Billy has to break it, so that he can put his cock all the way up inside you."

Momma paused for breath, then continued, "Billy's got to push his penis all the way up inside you, so that his sperm will make a baby in you. He's supposed to cum as far up inside you as possible, if he's going to get you pregnant."

Oh Wow! It sounded like Momma WANTED me to have Billy's baby. Then I remembered what Momma had said about me being too young. Besides, she hadn't said a word about me and Billy getting married. I relaxed.

"OK Momma," I said. I guess I could put up with a little pain for my big brother. I had taken several shots, down at the doctor's office, and I hadn't complained. Besides, Momma said that this would only hurt the first time or two. I had even been in fights with MaryJane, down at the school, and had learned to ignore pain, if it was important enough. Momma seemed to think that this was. Besides, if I didn't do it now, it seemed that I would have to do it later sometime. Better to get it over now. I grit my teeth, and said through my clenched jaws, "go ahead, DO it!"

Billy did. At Momma's direction, he put his cock up against my little crack, rubbed the head up and down to get it slippery, then PUSHED it up inside me.

There was a moment's discomfort, as my unused little cunny stretched around my big brother's invading prick. Then, a moment later, there was a slight sting inside me, followed by a dull ache, as his cock slid almost all the way inside me.

I was almost disappointed. THIS was the big pain I had been so afraid of? Heck, it hurt worse, every time I banged my knee on the cupboard. Gee! I felt like yelling and screaming as if I were in horrible pain, just as a joke. Then I saw Momma and Billy's worried faces. No, I couldn't do that to them.

"It's OK," I reassured them, "I hardly felt it." This was true. Even as I spoke the throbbing ache died down, and pretty soon the only sensation I felt, was that of being stuffed. Yeah, bloated like a turkey. Remember I had never had anything up inside my crack before; and Billy wasn't all THAT small. Not nearly as big as he is NOW, of course, but remember, I was only 6 years old myself.

Momma seemed relieved. Later she explained to me that not all girls had it as easy as I did. In fact, she was able to give me a couple of horror-stories that her girlfriends had told her about losing their virginities. All I know, is that it didn't hurt me much at all.

Once Momma was sure I was OK, she told Billy to start sliding his cock in and out, until he was ready to squirt. So Billy did. It couldn't have been over a minute, that Billy slid his cock in and out, before his face squinched up, and he groaned, "Oh Momma! I'm Gonna. . . Augh!"

I was a little disappointed. From being a "Pain in the snatch," if you'll pardon the expression, it had gone to feeling good. In fact, I was really starting to like it, when I felt Billy tense up on top of me, and then I suddenly felt wetter inside.

Momma acted fast. Seeing my brother starting to cum, she got behind him and PUSHED hard!

I let out a squawk, as my brother's cock slid another inch up inside me.

"You want to squirt your sperm as far up inside your sister as you can, if you're going to make a baby inside her," explained my mother.

I felt another pulse of my brother's cock, then another. My big brother was doing his best, to get me pregnant. I didn't mind. By that time, I was starting to get turned on by the idea of having my own brother's baby. "Do it," I encouraged him, "cum in me. C'mon big brother, squirt your sperm in my tummy, like Momma says, and make a baby in your little sister."

Momma looked at me, surprised, then grinned. "Yeah Billy," she encouraged, "knock your little sister up. Let Diane feel what it's like to have her own big brother's baby growing in that cute little tummy of hers."

Well, my big brother tried. He jerked and spasmed on top of me for over a minute, trying to fill my little tummy full of his gooey white stuff. I was so glad I could make my big brother feel so good. I held him, as his spasms turned to shudders, and finally just hoarse breathing as his mighty ejaculations turned into squirts, and finally just a trickle of sperm leaking out of his cock, and into my welcoming young womb.

I felt so proud of myself. Not only had I gotten fucked for the first time, which most girls don't get to do until they are at least 10, and sometime even 12 years old; but here I was, only six, and already practicing making a baby with my older brother.

Momma seemed to be proud of us both. "That's good," she said, "Now Billy, I want you to be sure and practice making a baby in your little sister at least once a day, from now on. Understand?"

Wordlessly, Billy nodded. He was just getting his breath back, but I knew he had liked what we had just done. In fact, I was fairly sure that he liked it well enough that he wouldn't find it hard to keep his promise.

Momma turned to me. "Diane," she said, "I want you to be sure and tell me, if your big brother doesn't fuck you at least once a day, from now on."

"I promise, Momma," I replied. Wow! I was happy to hear Momma making sure that I learned something too. I figured that if my brother and I did this regularly, then maybe I'd have a chance to learn what Momma liked about it so much.

Well, it took a few weeks, but eventually I did.

As you can guess, my big brother did more than his duty. From that day on, Billy fucked me not only once a day, but two, three, four, and sometimes even five times a day. The next day, Momma showed me how to suck Billy off, when I was too tired, or too sore to fuck. After about a week, she showed me how to take it up the ass, but I didn't like that as much. Billy and I only did that about once a month or so.

After about a month, when I finally learned how to cum, and Billy and I had been "practicing" making a baby for quite a while, I asked Momma if she was going to make us stop, now that we both seemed to be pretty good at it.

"Oh no!" she reassured me, "Not unless you want to. You two kids can keep on practicing making a baby, until you get it right."

"Oh," I said, then thought about it. I liked the idea. "OK Momma," I said, then went in search of my brother, so that we could get in some more "practice."

For the next 4 years, my brother and I practiced making a baby, until we got it right. Momma had Billy move into my room, so that I could go to sleep with my big brother's cock inside me, so that his sperm wouldn't go to waste, if he had a "wet-dream." We'd get up in the morning, and fuck. We'd come home from school and fuck. We'd go to bed at night and fuck, of course. In the course of a year, I doubt if there was a period of 12 hours straight, that I went without having a fresh helping of my big brother's sperm soaking in my eager little womb.

By the time I was 10 years old, Momma had explained everything, and told us that we didn't really have to make a baby together, if we didn't want to. She told me that it had been a pretty cute idea, at first, but she didn't want to force me into having an unwanted child.

The trouble is, I was already sold on the idea of having Billy's baby, and so was Billy. When Momma told us that I was almost hold enough to have a baby "for real," our "practice" sessions became even more frantic, if possible. By this time, Billy had been "practicing" making a baby in my little sister also, for over a year. It was so cute, to see the little 7-year-old girl squirming underneath her big brother, as Billy tried his best to plant a baby in our little sister.

Well, as you can imagine, Billy and I eventually got so good at "practicing" making a baby, that we actually got to be pretty good at doing it. I had a son, by my own big brother, when I was a little over 11 years old.

Within two weeks after Michael was born, we were working on making a little sister for him. After all, we didn't want to get out of practice!

My little sister Gina got to be pretty good too. In fact, she had only been practicing for 4 years, when she finally did it right. The little girl looked so cute, with a big belly at only 9 years old. Still, she seemed to be happy about it. Both of us have done our best to make our mother proud of us, by "keeping in practice."

My little sister seems to have learned her lessons better than I did, because she's almost caught up to me. The little jerk has had 6 babies in the last five years, while I've only had seven total.

Momma's so proud of us both. As I said, Momma's a pervert. Oh well, so am I. Yesterday, I taught my 11-year-old son how to make a baby in his little 10-year-old sister. Since Danielle has already had her first period, I don't think the little girl is going to have to practice for 5 years, before she learns how, unlike me.

Afterwards, I had him practice what he learned about making a baby with Danielle, by having him try to impregnate Marsha, Dawn, and Judy. We all hope that he'll be able to father at least two or three kids on each of his sisters, before they get out of grade-school.

Gina and Carol are too young yet, for Mike to fuck. Besides, his little brother Jimmy is going to need a little sister or two to practice making babies in, when HE gets a little older, as well.

I finally appreciate the pleasure Momma must have had. To see your own son's cock stretching your little girl's tight little cunny, as the boy ejaculates his sperm in his own sister's eager young womb, is SO sexy. In fact, it has gotten me so hot, thinking about our little girls carrying their big brother's seed in their cute little tummies, and maybe (In Danielle, I hope) his baby too, that I'm going to see if I can get in a little more "practice" myself, with MY big brother.

Hopefully, he hasn't already spent himself in my little sister. Oh well. If he has, it won't take all THAT long to get him up again. Teaching the kids how to fuck, has gotten him almost as horny as me lately.

I hope Danielle has a boy first.
