“Uhhh!” I panted, fucking her even faster as multiple spurts of my warm semen filled her up. “Margie, your cunt's sucking the cum right out of me! Ohhh, God, you're such a slutty little girl! I love it!”
“I'm still coming,” she told me, her heels digging into the laundry pile as she pushed her crotch up into me. With her bare arms around my neck, she was nearly squeezing me to death. “Fuck me more! Fuck me! Don't stop, don't stop! ”
And so it went, the two of us youngsters squirming our naked sweaty bodies against one another on that pile of dirty laundry until we were finally both limp and spent and trying to catch our respective breaths.
When my cock finally slipped out from between her sprawled-open legs, a large splurt of my cum oozed wetly out of her swollen slit and got on one of my mom's good blouses.
I looked at it, studied it.
“That'll take some pre-soaking,” I told Margie. “But I think it'll be okay.”
I stood up in the laundry room, the washer finally finished as it made that chunking noise. But the dryer kept hotly going. The usual weird lint smell was in the air, mingling with the hot underage-pussy-full-of-cum smell of my little sister.
It wasn't a problem. I knew the odor would be gone before our parents got home, sometime after six or so.
Margie was still lying on her back, her eyes closed and her slender bare legs spread wide, her breathing slowly returning to normal. Her slick hairless pussy was one of the most exciting sights I'd ever seen in my young life, pink and perfect and still glistening with her wetness.
I loved looking at it. And up it.
It looked even more exciting with my semen leaking out of it, the narrow crack of her bare ass filled with whitish liquid before it slowly pooled onto the clothes.
It was, in fact, the main reason we started having sex in the first place.
After a secret afternoon of computer porn, I'd given her $5 to see her pussy. And she'd immediately shown it to me. As a skinny, precocious little 9-year-old, she just pulled her shorts and panties out in front, letting me take a really good look.
I gave her another $5 to touch it, which lasted about ten minutes before she finally slid off her shorts and panties and got down on the floor with her legs spread. She was liking it as much as I was.
“Keep touching me there,” she told me, after those first few minutes. “It's making me all shaky…”
Then, of course, one thing led to another, much of it inspired by our further afternoons looking at porn on the computer in my room.
Monkey see, monkey do, my dad always said.
From the stack of dirty laundry where she still lay sprawled wide-open, Margie opened her big blue eyes and looked up to me. Then her sweetly perfect face broke into a shy smile.
Whenever we had sex, she always got shy and nervous after she had a climax or two. It was as if she was embarrassed at what we'd done, but only had the presence of mind to realize it after she came a couple of times.
Girls.
But this time, she said to me, “Patty wants you to fuck her, too. She's all excited about it.”
I just looked down at my kid sister.
“Margie!” I said, shocked. “You told her? This is supposed to be a huge secret, what we're doing. It's worse than sex-it's incest.”
My little 4th-grade sister just shrugged.
“I was rubbing her pussy that night I stayed over, making her come, and it just sort of slipped out,” she admitted, finally getting up. “As soon as I told her, I knew I shouldn't have, but it got her crazy.”
I just shook my head.
Her best friend, Patty, was a really cute little 10-year-old in the 4th grade as well, with long dark hair and a spectacularly round-looking butt for such a youngster. It didn't surprise me that Margie was fingerfucking her, making the other girl come, because my kid sister was excited by anything that had to do with sex.
She just couldn't get enough of it.
“Patty wants me to fuck her?” I asked. “She said that?”
Margie nodded, then used a soiled pair of our mom's panties to wipe her pussy and the crack of her butt clean. After, she started pulling on her own clean underpants, then lightweight shorts and a top that we'd already washed.
“Mom said Patty can stay over tomorrow night, since it'll be Friday,” Margie said, as if she'd already planned it all. “She'll come home with me after school. Then we'll have a few hours before mom or dad get home.”
I studied my sister for a moment, amazed as always at her true nature.
Margie looked like the most innocent little girl in the entire neighborhood, at 4'6” and 79 pounds a sweet flawless angel who seemed both too naive and far too young to have the baser sexual urges she always had.
The ones that caused her to enjoy fucking so much.
“Are you gonna join us?” I asked, knowing the answer. “While I'm fucking her?”
Margie gave me a surprised look.
“I told Patty I'd lick her, to get her pussy ready,” she told me. “You're going to love her pussy-she gets crazy wet and excited. She comes like you can't believe and she's dying for you to fuck her…”
“You had me at 'pussy.'
“Funny,” she said. “And I saw that movie on TV, too.”
I started pulling my clothes on.
Then I froze, still in only my tee-shirt, and had my great thought, the one that soon became the Student Sex Club. I looked to my kid sister, studying her so thoughtfully that she finally asked, “What? Justin, what are you thinking?”
And I reached out and took her small hand in mine, which surprised her.
“Margie,” I said, seriously. “If my dick got hard again, right away, could I fuck you again?”
She looked into my own blue eyes, just as seriously, clearly trying to fathom what I was up to. But she nodded, eagerly, it seemed. And she slid her free hand down into the front of her shorts, giving her bare pussy a quick squeeze that made her smile crookedly.
“Yes, yes and yes,” she told me. “I always want to. You know that. And I'm still all wet.”
I nodded, then released her hand so I could pace in a small circle, my preferred way of thinking things out. She watched me with open curiosity, her eyes widening when I stopped back directly in front of her.
“Should I pull down my shorts?” she asked, her need for further sexual relief obvious in her voice. “Do you want to screw me doggy-style? I always like it like that. Or you can get some Vaseline and put it in my butthole…”
“Keep your pants on,” I told her. “But I like your thinking. What if…?”
And I stopped, working it out in my head.
It was so obvious, a solution to my kid sister's never-ending sexual urges and a way to make us both a little bit of money. Plus, I could get more than just Margie and Patty to fuck for me.
My idea involved many girls.
“What if what…?!” she was dying to know. “Come on, Justin, do you want to fuck me again or not?”
I glanced at the pile of dirty clothes, the residue of our recent coupling still evident. If we wanted to get those protein stains out of them, we needed to get everything into the washer right away.
Like drying egg yolks on a plate, cum required a lot of quick attention.
“Laundry first,” I told her. “Then I'll fuck you again. But, Margie, if there were, say, five boys here instead of just me, would you let all five of us fuck you? Like, one after another?”
Margie just stared at me, the thought of it, the image of it all, running through her nimble little 4th-grader's mind. Like me, she'd intently watched, bright-eyed with open fascination, all the gangbang videos we found on the Internet.
In fact, she always fucked me extra hard on those particular afternoons.
“Maybe…” she admitted carefully, her eyes sliding away from mine. I'd gotten her youthful attention all right, but I think I embarrassed her as well. “Which boys? Like older, in your grade?”
