"Get Between Your Sister's Legs!"

"It's time you two kids learned about sex. Now both of you get on the bed," said my mother. Obediently, Karen and I started to climb on our mother's bed. "Not that way, you idiots." Momma sounded disgusted. "Get undressed first!" Karen grinned at me, and I grinned back. We knew that Momma wasn't really mad, just impatient for some reason. Still, we hurriedly stripped out of our clothes, before getting on the bed, as Momma told us to.

"Now you lie down there, and lift your legs, and spread them," said Momma to my little sister. "Then I'll show your brother what to do." "Yes Momma," Said Karen. "Then what?" "Then I'm going to teach you two how to make a baby." I didn't say a word. I figured I already knew how babies were made, but if you think I was going to tell Momma that, you're crazier than I am.

Especially, as it was beginning to look like Momma was not only going to TELL us how babies were made, she was going to give us an actual demonstration. I wondered if she was going to actually let me stick my cock up inside my  little sister, or just show us how. In either case, it just might lead to me being able to ejaculate my sperm inside the little girl.

If not now, then maybe later, after Momma's "lessons." I figured that Karen wouldn't object to my advances, once Momma had broken the ice, so to speak. It turned out, that Momma was way ahead of me. "Now you get between your sister's legs," she instructed me. "I'm sure you know what to do then." I couldn't believe it. Momma actually WANTED me to fuck my little sister? "You mean. . . ?"

I asked. "Uhhuh," said Momma, "I'm sure you'd like to, so get up there and teach your little sister how to make a baby." I couldn't deny the "like-to" part. My cock was so swollen, I thought it would burst. Still, this WAS my little sister. "Uh, Momma?" I asked, "What if she. . . ?" I couldn't say it. I tried again: "I mean, what if I. . . ?" I still couldn't say it. Momma could. "Get her pregnant?" she asked. I nodded.

My cock bobbed in time with my head, leaking dribbles of pre-cum on my little sister's leg. "It's OK Mike," reassured my mother. "Karen's  on the pill. Besides, it'd be kind of nice, to have another child around the house. So don't worry, just do it. Let's see if you're man enough." I couldn't believe it.

Momma not only didn't seem to care, if I got my own little sister pregnant, she actually seemed to WANT me to. Well, I might not believe it, but that didn't stop me. I pushed my pre-cum dribbling cock up against my little sister's tight little hole, and shoved!    "Ow!" said Karen, "That hurts." "Sorry," I said. Well I was, but not TOO sorry.

My little  tight little cunny was wrapped around the head of my leaking penis squeezing it in a manner that threatened to have me squirting baby-juice all over the inside of her vagina, before I even got all the way inside her. "I've got to get the rest of it in." I warned her. "Does he have to, Momma?" Asked Karen.

Momma's face was bright red with excitement, as she watched my cock slide a little farther into my sister. "Yes dear," she replied. "He's got to get it all the way up inside you, if he's going to impregnate you properly." Momma's words almost had me spouting my sperm in my sister's tight little cunny, before I was fully inside her. WOW! Momma actually WANTED me to impregnate my little sister.

My cock must have grown at least another inch, at the very thought. Still, as Momma had previously pointed out, Karen was probably too young yet, to get pregnant. I pushed in a little harder. "Ow," said my sister again, then she bit her lip, to keep from squawking. I didn't like the thought of hurting my little sister, but the tight ring sliding down my engorged penis, was too exciting for me to stop now.

Suddenly, the rest of my cock slid home in my little sister's belly, as I felt the tight ring of her vagina come to rest around the base of my cock. In the meantime, ANOTHER tight ring slipped over the head of my penis, and a little over halfway down. I knew I had just busted my little sister's cherry, and the remnants were still squeezing on my prick. I looked down, to where my penis vanished into my little sister's crack.

Her tight little cunny was obscenely stretched around the base of my prick, and my fuzz of pubic-hair was rubbing against their smooth nakedness. I couldn't believe it. I had cock all the way up inside my own little 18-year-old sister's tight little cunt, and I was actually fucking her. Momma seemed to be as excited as I was. "That's it," she encouraged.

"Fuck your little sister. C'mon boy, do it. Teach your little sister how to make a baby. Go on Mike, knock the kid up." The only one who didn't seem to be enjoying this, was Karen. Still, she didn't seem to mind all that much. In fact, she actually encouraged me to go on, as she seemed to want to please Momma. "Yeah Mike," she said, gritting her teeth, and pushing back at me.

I could see a trickle of wet seeping out of the corners of her eyes, as the fought back the tears, but she still continued to egg me on. "Do it Mike," she said. "Knock me up, like Momma says. Teach me how to make a baby, so I'll know what to do, when I get married. I don't mind Mike. You can make a baby in me, if you want to."

All the time, she kept rocking back and forth, sliding my cock in and out of her tight little hole.   It was too much for me. Feeling my little sister's tight little hole squeezing on my swollen cock was bad enough, but hearing BOTH my mother and little sister begging me to knock her up was too much. I began squirting my sperm all over the inside of my little sister's tight little cunt.

Oh God, it felt good to let that load of baby-juice go. Right where it belonged too. Right up inside my own little sister's welcoming young womb. Oooohhh, it felt good! Seeing me lose control, and jam my exploding cock up inside Karen's little slit, Momma knew I was doing it as well. "Feel it?" she asked Karen. "Feel your brother squirting something inside you?

That's his sperm. The stuff that makes babies in little girls. Your brother's squirting the stuff that makes babies right up inside you, and he's going to make a baby in that cute little belly of yours. Go on, squeeze your brother's cock, and make him squirt inside you. That's it Honey. Make your brother squirt LOTS of the stuff that makes babies right up inside you, where it belongs."

All the while Momma was saying this, my cock continued to pulse inside my little sister, sending wave after wave of thick sticky cum up inside the little girl's body. I couldn't believe how much sperm I was ejaculating inside my little sister. On and on it went, until finally I had no more to give. Still, my penis ached with dry squirts, as I tried to send still more baby-juice into my little sister's womb.

It was no use, I had given her every bit I had. Exhausted, I collapsed on top of my little sister, while her cunny kept my shrinking cock warm, squeezing out every last drop of incestuous sperm up inside her, where it belonged. Afterwards, Momma told us both to just lie there awhile, so that my sperm would have a good chance to soak into Karen's womb, before we got up.

That night, Momma had us "practice" again. In fact, from then on, until I went to college, Momma insisted that Karen and I "Practice making a baby." at least once a day, while she watched. Quite often, we "practiced" much more often than that. In fact most of the time I slept in my little sister's bed with her; and we'd practice making a baby before we went to sleep, and once again in the morning.

It was fun. Besides, it sure made Momma happy, to know that her two kids were working to give her the grandchildren she wanted. Two years later, when Suzy turned 18-years old, Momma had me teach HER how to make a baby, as well. She got to be almost as good as her older sister. I imagine you think that with all that "practice" we'd get so good at it, that we actually succeeded some time. Well, that's another story.
