“I’m bored of video games.”
“You’re bored of everything!” Chris said, giving Heather a sideways glare.
“Well it’s just—” she bit her lip, frustrated, “You keep always beating me, because you already play it a ton!”
“So you want me to go easy on you?” the boy said looking at the slim girl skeptically.
“Maybe I wanna do something else,” she huffed, blushing and looking the other way.
“Like what?” he asked, in an honest curiosity that brought her to look him in the eyes again.
“Have you heard of sex before?” she asked nervously.
“No, what’s sex?” he asked, leading her to smile in relief.
“It’s a um... thing you can do,” she said hopefully, “My dad kind of... showed it to me before, and I really wanted to try it, but he wouldn’t let me.”
“And you wanna try it with me?” Chris asked, sitting cross-legged.
Trying not to stare at the groin of his shorts, Heather said, “Y-yeah. I was just... watching my dad do it with his friend, and it really made me wanna ...do it.”
“Why wouldn’t he let you?” Chris asked, a little worried, not even noticing Heather checking him out.
“Well, because he said it might make me... pregnant,” Heather replied, tentatively, and at Chris’s blank look, she said, “Pregnant means I’d have a baby growing in my belly. It’s how girls get to be mommies.”
“A baby in your belly?” he asked incredulously.
“Yeah, it seems weird, but it totally makes sense!” she replied in shock, “I already have a place for a penis to go into my belly, and a baby needs to grow from somewhere.”
“You have a place for a... penis?” Chris asked, grimacing in confusion and disgust.
“Look, I’ll just... show you,” she said, blushing, “It really does make sense though.”
Then she sank onto her butt, and started struggling her pants down. Her panties swiftly followed, and she spread her naked legs, slightly touching her belly as Chris looked into her mysterious groin. “See, this is a... a hole,” she said, still blushing as she spread herself open with two fingers. “Every girl has one, a-and I don’t have a penis.”
“Oh, yeah you... you don’t,” he said in distant realization.
“Daddy’s penis just started getting big, and... and thick, and sticking out from him,” Heather said, sort of pantomiming it as if coming from her groin, “So it was more like a... a pole that he pushed into his friend, r-right here.”
Heather was getting worked up just from thinking about it, and feeling her fingers slowly moisten spreading her inner folds. And Chris was already on his way to a boner, but hadn’t realized it until now. “Your, um,” Heather said hesitantly, removing her hand and closing her legs, “Your penis is gonna get that way too,” she said, “And you can... push it into my place, and that’s what sex is.”
“My penis?” Chris asked self-consciously, looking at his groin.
“T-take off your pants and stuff,” Heather suggested, “Then you can see it... getting big and ready to go into me.”
Chris wasn’t about to say no, after she took off her pants for him. So he did the same, and his penis was looking... sorta thick? “It uh... feels kinda tickly,” he said, gripping the little thing in his fingers.
“Here, lemme try,” Heather said, scooting up to tangle her legs with his, so they both could reach his penis, “My dad’s penis got really big when his friend rubbed it.” She touched his hand, and he pulled it reflexively away from his groin, watching in befuddlement as Heather’s warm fingers felt at his penis, then lifted it up to wrap around it.
“Is... is this okay?” Chris asked a little nervously.
“Wow, you really do have a penis...” Heather said distantly, “It’s so soft.”
“C-can I touch yours too?” Chris asked, looking at the groin of the girl sitting before him.
“Oh, yeah!” she said, releasing his penis, and leaning back, “Just be careful, but try to... pull it open and stuff, and your fingers uh... you should be able to see how it does go into my belly.”
Chris touched her velvety soft petals, pushing his fingers within before pulling them out and exclaiming, “It’s all... wet!”
“Yeah, it gets wet um... that’s something that makes a boy’s penis feel really good, when it’s in a girl who’s wet,” Heather explained with difficulty, “It sure made Daddy’s penis feel good. He said so a lot. So I just... get all weird and wet in there, especially thinking about what... Daddy did to his friend’s place.”
Cautiously touching again, Chris spread open Heather’s nether lips with his probing fingertips. “Ha ha, it’s all slimy,” he said gently teasing, “This’s really okay?”
“It’s supposed to be slimy,” she said resentfully, shivering at the feel of his probing fingers. Looking away, she added, “Try to... g-get way in there. See how far it goes into my belly.”
“W-wow, my fingers are going all the way in this... place,” he said, as his index and middle finger slid up into her vagina.
“How’s it uh, feel in there?” Heather asked hopefully.
“It’s really hot,” he said, “Not burning my fingers but...”
“Y-yeah, that is kinda weird, but it’s just how my belly works I guess,” Heather said, risking a look at her own groin. She touched her belly right above her labia, saying “Your fingers are inside my belly, see? Right here.”
“Yeah, this is totally crazy,” Chris replied, transfixed by what was happening to her, “You just have a... place going into your belly down here?”
“Instead of a penis,” she explained, biting her lip as his fingers stopped exploring and just rested in there distractedly, “I have a place for a penis to go into. You wanna... put your penis in there?”
“I guess, it... woah,” Chris said, realizing he’d managed to achieve something of an erection. He pulled his fingers out of her, coating his penis in her juices as he explored what happened to it.
“Your penis’s getting ready I guess,” Heather said, “It has to get really big, then... push into my place. Your um...” Reaching under his hand, Heather shyly stroked at his testicles. “These are your balls,” she said, as the wrinkly scrotum shifted strangely under her fingertips. “Daddy said they have a special seeds inside, but it’s more like a white goo. And you’re gonna take that seed from your balls, and it’ll come out of your penis, when it’s inside me.”
She touched the tip of the boy’s stiff penis as he panted, squeezing it in his hand, Heather saying, “Right out here. Then when you put your seed out of your balls into me, it starts... making a baby grow in me.”
“I-it sounds amazing,” he said heatedly.
“It sounds amazing to me too,” Heather said, staring openly at that slim boy’s penis, stiff and erect. “I started really wanting a baby in my belly, and whenever I think about it growing in there, I get wet, and...” She lay back, spreading her labia with two fingers, “And that means I’m ready for a boy to put a baby in there. So can you put your penis in me now, and t-try to get your seed from your balls into... me?”
“O-okay,” he said, rising on his knees to scoot towards her, “So I just...”
“Just make it so your penis goes in there,” she instructed, “Daddy was lying on top of his friend when he did. And I’m laying just like she was.”
He did so, the head of his penis smushing into her hot vulva. “Al...most...” she said impatiently, “Just wiggle it around in—there! It’s starting to... oh wow.”
Releasing his hand from holding it, Chris inexpertly pushed all the way in, in one smooth stroke, his hips colliding against Heathers. His cock ensheathed in her hot vagina, they stared at each other in shock.
“It...” Heather broke the silence, “It feels a lot different than your fingers.”
“It feels a lot diff...” he said uncertainly, instinctively humping in and out of her, “It’s so hot, and wet in there!”
“That’s what Daddy said,” Heather said in confused ecstasy, a serene smile playing on her face at her friend’s soft strokes. “And then I say it’s so hard and thick, because it is.” The humping started to intensify between them both, as she said, “It looks... small but it feels... it’s really stretching me, my place is...”
“The heck are you kids doing in here?!”
They froze, looking up guiltily at the flabbergasted babysitter. “We’re um... having sex?” Heather tried from where she lay underneath Chris, full of his penis, with the most innocent look she could imagine.
“I’ll say,” the babysitter said in shock, sitting back on the couch with a thump, “You’re not worried or anything?”
“Of course I’m worried!” Heather protested impotently, blushing as Chris started thrusing again, “I just... really... wanted it... and it feels so... good...”
“Please let me put a baby in her,” Chris panted, eyes on nothing but the hips of the girl his penis was penetrating, “I wanna do it now. I wannit more and... more...”
“You can’t even stop, can you?” the babysitter asked teasingly. The two children may have hesitated, but just kept humping together, with needy whimpers. “Well don’t let me stop you,” he said, pulling down his pants enough to whip out his own much larger penis, “Go ahead and have sex, and maybe when he’s done, I’ll finish in you too, Heather?”
“What?” Heather gasped, holding this boy who was fucking her.
“You think he’s got seed, wait’ll you see my own,” the babysitter said smugly, stroking his stiffening erection, “I’ll fill up your little cunny with my cum, until you’re sure to have a baby.”
“I’m gonna have a baby!” she moaned in delirious delight, hugging and humping, rolling her hips to pull him in and out, in and out.
“I wanna p-put seed in her,” Chris gasped, staring intensely at the writhing girl beneath him, “H-how do I know when I put a baby in her?”
“Oh you’ll know,” the babysitter said, craftily, “It fills you up with tingling pleasure then just rushes through you. Your dick’s gonna start jerking and pumping all on its own, making sure every drop of your seed gets into her. Just keep going until you can’t... go anymore, and you’ll push your hips hard against her, and cum right into her.”
The babysitter sat there jerking off, and the kids lay there on the floor, eyes scrunched shut as they urgently fucked each other. Their breathing deepened, and their hip movements smoothed out into an instinctive, primal rhythm. Chris barely realized at the end, exclaiming in his thrusts, “Oh, it’s... getting... so... it’s... it’s... it’s...” He shoved deep then, as the horny girl bucked under him.
“Getting ready to cum?” the babysitter asked.
“H-ahhh!” was Chris’s urgent answer, as he started to impregnate his friend. He shuddered, holding deep inside her, pumping out his cum, as she stopped fighting and relaxed, staring at the ceiling and declaring,
“Oh... oh wow...”
“Well you’re pregnant now, and he’s done fucking you,” the babysitter told Heather as the exhausted boy relaxed atop her.
Heather looked at him with lusty, anxious eyes, saying, “Maybe you could ...fuck me?”
“I don’t think you’d fit!” the babysitter declared, indicating his massive tool, from a youngster’s perspective at least. “But c’mon up into my lap. I’m gonna jerk off like this until I climax, and then I can jam it in just enough to put my cum in you, too.”
Heather did, and it was kind of awkward, but she lay alongside him, trying to help him jerk off. She tried to make him fit. She sat on his dick, and enveloped it in her folds, groaning and grunting and pushing, but there was just no way she could stretch that much. So she lay there on the couch with him, as Chris watched in fascination, using her labia to stroke the base of the babysitter’s penis, and his scrotum, adding lubrication for his hand to jack off with. Sticking her fingers in herself, trying to stretch open more.
“Alright, I’m... close...” the babysitter said, “Wanna sit on my... dick again, so I can get it all into you?”
“Y-y-yeah, I really... wanna,” she said breathlessly, scrambling to climb up him and press down on the head of his penis again. Her vagina fought with his hand, as she tried to claim his penis, and all he said was, “Almost... there... more–more...m-mmmh!” Then he released his penis to grab her hips, just as she sank down on it, and pulled her onto his penis further.
Heather shrieked at an overwhelming, incredible, wonderful, painful stretching sensation, and then a thick spurt of hot seed erupted into her. “Oh... oh... ohh... oh,” she panted, as she got pregnant right in front of him. Hunched there on him, embedded on his penis as if her vagina were trying to wrap around a bedknob, feeling seed rushing up into her birth canal, Heather orgasmed hard.
“...is she okay?”
“Yeah she’s fine, just it started feeling really really good for her.”
“H-how long before...”
“Doesn’t usually last more than a minute. She can probably talk now, but this little mother just wants to lay there and feel amazing.”
Heather just laughed in delirious joy at the two attentive boys around her, as she prepared to grow their baby inside her.
Of course it wasn’t until much later, when Heather could actually get the babysitter’s dick to fit inside her, that she got pregnant. Her first period or lack thereof was quite uneventful, and by the time her parents realized what was going on, Heather was serene, fat with child, and just turning 13 years old when she began to give birth.
Even then, she hid the signs of labor, and it wasn’t until her math class after gym that her contractions became too much for her to hide. So with the panicked math teacher run to get help, and the rest of the students gathered curiously around (or hiding in the other room), Heather huffed, and pushed, and screamed in the primal fury that filled her as she struggled to hurt herself more to get that baby out of her. And as she saw herself in the mirror someone had brought over on request, her latest push made her labia distort obscenely, stretching open around the smooth round head of a child emerging from between her legs.
Heather was between contractions when the ambulance pulled up and the doctors rushed in. “It’s okay!” she called out to them drunkenly, from where she lay on the absolutely ruined classroom floor, “She’s half out, already!”
