She wanted it so bad, it was scary. Drawing pictures of lesbians loving each other, touching herself, she just started… thinking. Thinking about a colt she’d met the other day, how nice he was, and what it would feel like if his penis went in her vagina. She wasn’t supposed to think about that stuff. She didn’t want to get pregnant! She was just a filly, not some kind of grown up mare!

She had started… noticing the colts around her. How they always had those fascinating balls hanging between their legs. She wondered what they felt like. Supposedly, colts had this… thing that came out between their legs, called a penis. Heart Mender had never even seen one before though, just heard about them in hushed whispers from her friends, who were all fillies.

Her friend Spice Tassel said that… it felt really good when a colt puts his penis inside you. That Heart had a… pocket between her legs, that a penis could go into. And Spice said she was… pregnant, and going to have a foal. Heart Mender wasn’t supposed to think about boys, or getting pregnant, but though she was afraid to ask more, what little she knew was so tantalizing. She started… noticing colts, and wondering what their penises looked like.

Of course her mom had immediately gotten mad, and told Heart to never think about those things, or talk about them with anypony, because she’s not some sort of slut. Heart Mender didn’t want to be a slut, whatever that was!

Heart had looked at her own rump in the mirror, and she could sort of see how she had a little pocket back there, where her labia hung neatly beneath her little asshole. It sort of made her… feel really good when it flexed under her touch, and she even saw it, a wet pink fleshy flower emerging from her innocuous pale-furred package. It made her squeak and turn away from the mirror, then turn her rear back to it, poking at it in horrified fascination, pulling that… pocket open, where she was moist and bright pink within.

She was drawing colts, and trying to figure out how their… penises would work, but she hadn’t met with much success. Not like any colt would go and show her, after all, right? She thought about asking Spice, but… she was too shy, really. It was okay if Heart thought about fillies, and touched herself imagining their pink wetness, but it was just impossible that a filly like her could ever become a mother, so she avoided any information on penises, colts, and anything like that.

Still, she found herself drawn to them. She started… looking for excuses to hang out with colts. She couldn’t join a sports team, since they segregated fillies and colts, but she could join an activity. She tried to find one where she could get the best… look at them, and photography seemed about… right. So she joined a photography club, with little idea of how to use a camera, but ponies there were happy to help her learn, and soon Heart Mender was pretty happy with the photos she was taking.

…colts were happy to help her learn.

Heart Mender shouldn’t have been thinking like that. It was too dangerous. She couldn’t be… thinking like that. A colt was too powerful, for what he could do to a filly. If she ever got alone with them, they could …do what Spice Tassel did. And Spice had… a really stiff belly. Supposedly that was a tiny foal in there. Heart was… afraid of wanting it, no no, she just liked fillies, and maybe colts who were gay, and… really hot.

She… took pictures. Sometimes she even got a colt’s rear end in those pictures. Those, she hid for herself, taking them out to look at them wide-eyed while she… rubbed herself feeling better and better. Colts had a little asshole just like her, but instead of a pocket, they had that ballsack. And supposedly somewhere in all that was a penis. She really didn’t know. She just liked… looking at it, and wishing that a penis could go inside her. Like a… ball in a cup, she supposed, because her fillyhood was sort of like a pink, fleshy cup, when she spread her labia apart.

Heart Mender never orgasmed. She got too nervous. She didn’t even know about orgasm. She just felt… better and better when she touched herself, but also more anxious, and more… hungry, but not for food. She always stopped when it started getting scary though, and Heart Mender was not a very brave pony.

Her saving grace, or her fall from grace depending on your perspective, was when she caught a colt photographing her rear end. A flash behind her, and she looked back, only to see a colt with blue hair hurriedly moving his camera away, looking in the other direction and blushing. This was a world shaking discovery for her, because Heart had to wonder, did colts find her as mysterious as she found them? She knew she had a… pocket as her friend called it, and how to pee, and everything, but did they? Did they know about that… weird squirmy thing she did, that made her pocket flex open and forward, then back inward again?

Heart started trying to get that colt to take pictures of her again. She felt like she wanted to help him, if he was as curious as she was about all this, and also she wanted… to find out if he was really taking pictures of her rear. So she just… dropped her camera on accident, right when Tinkerwing was behind her with his, bending down before using her horn to pick it back up again, which let her tail slyly bob upward. She held that position a moment, pretending to fiddle with the camera, to make sure it wasn’t broken. There was a flash behind her.

Heart looked over her shoulder faster than lightning, and he was… holding his camera pointed right at her, and he wasn’t looking at it, but rather looking at her. She stood up dropping her tail down, while he hastily looked away, the two meeting eyes for only the barest moment. But she was much more confident then, that he wanted to look under her tail.

It was ironic, because Heart Mender didn’t have a photo of under his tail. But she was afraid if she took one, he’d know, since he was doing it too. Just like Heart Mender figured it out, he’d figure it out too, and then… she’d get to put a penis in her vagina.

She held out a long time. She’d take pictures facing away from him, lifting her tail or moving it aside. She’s always stand in front of him, waiting for that flash as he took another picture of her rump. She… wanted to know what he did with all those pictures. He didn’t have a fillyhood to touch, so what was making him think about it? His penis?

But at last curiosity got the best of her, and she stood behind him one day, waiting until he was most certainly totally not paying attention, lifted her camera, and took a lovely picture of some pine trees, and that colt’s ass. He immediately looked behind him. Spooking, Heart Mender looked the other way, and trotted off in a panic, not really having anywhere to go, just… going behind the other fillies and standing there awkwardly.

That would’ve been the last time she ever showed her face at the photography club ever, but she was getting out of class, when she saw the colt waiting for her. They stared at each other for a while, before the colt blushed and took a step forward. The colt had deep golden fur, much darker than Heart Mender’s, and classy blue hair. He took a step back, then scrunched his muzzle and walked right up to her. “Uhm… hi,” he said.

“Hi?” she replied, internally panicking because what was she supposed to do? There were a bunch of students around who could all see them!

“I just wanted you to know, it’s…” he cleared his throat, “It’s okay if you um… took a picture of me. On accident.”

“Uh, okay?” she said trying to keep her voice from trembling, “I’m just gonna… go. Uh… you.”

“Tinker…” he said, but she’d already fled through the crowd.

“That was harsh,” her friend Coldberry said afterward.

“What was?” Heart asked, with a worried look at her friend during lunch.

“You know, when you told off that colt after class?” Coldberry replied. “I didn’t see it, but Ameralis did. You really don’t like colts, do you?”

Blinking, Heart said, “I didn’t say anything bad though. I just um…”

“Hey, if you didn’t mean it then you probably owe him an apology,” the blue eyed, pink furred Coldberry told Heart Mender. “Ameralis said he was just trying to introduce himself to you, and you acted like he didn’t exist.”

“I… I acted like he existed!” Heart Mender protested. “I just… I mean he’s a… colt.”

“Well, that’s just what I heard,” Coldberry said with a shrug. “It’s fine if you don’t like colts. We’re not supposed to be friends with them after all.”

“We’re not?” Heart Mender asked in confusion.

“Duh!” Coldberry said with a laugh, “Why do you think they’re always separating us now? We even have separate washrooms! And all the activities are colts only, or fillies only. And I bet your parents never said you could invite someone over to your house, if they were a colt. Mine were like ‘Don’t you even say that! It’s inappropriate!” She paused. “To invite a colt over, I guess,” she concluded.

“Well the photography club isn’t separated,” Heart Mender said, “That’s why… I mean… it’s not. Separated.”

“I thought that was a colt’s activity,” Coldberry said thoughtfully. “There are a lot of fillies in it?”

“N-no it’s mostly colts,” Heart admitted sheepishly, “But there are a few fillies in it. They um… go off photographing stuff together, but… never with the colts.”

“See what I mean?” Coldberry said with a bitter grin, “Fillies separate each other! Why can’t we be friends with colts?”

“I… I don’t know,” Heart Mender said, dissatisfied with her own words, and worried about what was going on here.

And that’s why she returned to the film club. Because the colt had said it was okay, so he probably wasn’t telling other ponies she was taking pictures of their butts, or with their butts included in it. The colt’s own butt was… exciting in that he’d actually talked to her, but the photo itself was kind of blurry. You could still see his compact orange balls though, beneath that vibrant blue tail. He… probably didn’t tell any other colts about this.

Heart Mender kind of wished she’d taken pictures of filly butts, so they wouldn’t realize how she wasn’t really a… filly who didn’t like colts. She kind of wished she could see the pictures that colt took, and ask why he liked them.

She got to the photography club, and nopony was suspicious at all. They asked why she missed the last meeting, but she said something about having to do extra homework, and they were okay with that. The other reason she returned to the club was here too, the colt from before. He wouldn’t even look at her though, the whole meeting. They certainly didn’t take pictures of pony butts that day, either one of them.

But after the club meeting, she saw a chance, following him as he left, and just… following him really. Not many foals were around for this after-school activity, so it was pretty much just the photography club. Once anypony else was out of sight, she picked up speed, trotting hastily up to him, saying, “Hey!”

He turned and looked at her, immediately blushing at the sight. Then he turned away saying, “S-sorry I thought you were taking pictures of me. It was just a weird coincidence, sorry.”

“No, it… I don’t mind if you take pictures of me either!” she blurted out.

He looked back at her in surprise as she blushed, saying, “I’m supposed to be apologizing. I didn’t mean to be rude back there. I just… you’re a colt, and the whole school could see us.”

“They can’t normally see us?” he asked skeptically.

“Not together!” she whispered urgently, “Listen let’s… can we talk somewhere um… under the entrance over there? C’mon!”

She trotted a few steps, looked back, and he started to follow, so she hurried to a more secluded spot. “Sorry, I just… didn’t want anypony in the club to see us,” she said, blushing as she turned to face the orange and blue colt, “Ponies have already been chewing me out enough for just… blowing you off like that the other day.”

“They have?” he said in confusion.

“Why, haven’t your friends been bothering you?” she asked in equal confusion.

“I don’t… really have friends,” he replied, as if that were just… normal.

“You have to have friends!” she protested, “There are so many colts at school!”

“Well, how did you make friends?” he asked, grumpily.

“I just… I mean like my friend Coldberry she comes over to play a lot,” Heart offered as a for-instance. “Nopony comes over to play at your house?”

“Who would, if I don’t know anypony!” he protested, “How’d you get her to start coming over?”

“Well I mean, she was in my first grade class, and… my… parents invited her over,” Heart Mender said, staring off into space.

“My parents just told me to make friends at the photography club,” he said, shaking his head sadly, “I don’t even really like photography all that much. I just… I mean, are we friends?”

She blinked, focusing on him, saying, “Well… yeah, I guess?”

“Then that’s how I make friends,” he declared. “I say something stupid to a filly after she gets outta class, because I thought you were taking pictures of me.”

“I… I… was,” Heart confessed. “I don’t really like photography either. I just didn’t have any other way to be with um…” She really wasn’t sure if she should finish that sentence.

“You were what?” he asked curiously.

“T-taking pictures,” she replied, “Of you.”

He was looking at her silently.

“I wanted to apologize!” she protested, “I just didn’t want everypony to see us talking in the halls. I didn’t mean to make you think I didn’t… like you.”

“Oh,” he said rather extremely noncommitally, “So… was it a good picture?”

“N-no it came out kind of blurry,” she said with a nervous laugh, “I was kind of nervous at the time.”

“Nervous?” he asked, “Why?”

She wasn’t sure she could answer.

At her silence, he said curtly, “Anyway it’s fine if you take pictures of me, is what I was trying to say. It’d be pretty stupid if I said that to a filly who didn’t even notice I was there, though.”

“Oh, yeah it would,” Heart Mender replied faintly, “I–I did notice you though. A lot. That’s why I was trying to help you take pictures of me.”

He stared at her in shock. This colt’s silence was kind of frustrating sometimes! “What?” she asked offendedly, “I’m just saying it wasn’t stupid you took pictures of me.”

“I didn’t say I took pictures of you,” he stated.

Heart Mender blushed so hard she felt like she was going to faint. “Uh—I mean—that uh—” she said intelligently.

“You… you knew I was taking pictures of you?” he asked in cautious astonishment. “But you were practically showing off your uh…”

“Uh…?”

“Not sure if I should finish that sentence,” he said with a blush.

“Been there,” she sighed, “It’s just… so weird…”

“What’s weird?” he asked.

“How hard it is to… make friends with colts,” Heart Mender said, looking at him honestly, “I didn’t think colts weren’t making friends with anypony. And my friend was saying our parents are trying to stop us from being friends! With colts, and fillies, I mean. Isn’t it kind of… weird?”

“It is, now that I think about it,” the colt said thoughtfully, “I just thought other ponies had some secret to making friends I didn’t know about.”

“They do,” Heart Mender said urgently, “My friend I met at a slumber party that my parents did, so we could meet! My other friend, she was… we were at a picnic thing, and they told us to go play together. My parents just set up these playdates, and that’s how I have friends. And most of my friends I know though my f-first friend. I don’t know how to make friends any more than you do!”

“That’s… that is really weird,” he said looking at her curiously, “I mean slumber parties are for fillies, like, doing makeup and stuff.”

“That’s not… all we do,” Heart said, blushing. “I’m not even really allowed to do makeup.”

“Well there isn’t anything for colts,” he said, “So maybe they just don’t want us to have friends. I dunno? Is it bad for me to have friends? My parents keep telling me to go make some though!”

“But they can’t introduce you at a slumber party?” Heart countered, shaking her head, “That’s just… kind of messed up.”

A moment of silence, and he asked, “So… you knew I was taking pictures of you?”

Blushing less heavily, Heart said, “Hey, it… makes sense. I mean, I don’t know anything about colts. So maybe you don’t know anything about what’s under my tail.”

“W-well, I also think what’s under your… tail is really, really pretty,” he replied.

Heart’s blush deepened again.

“It’s just really… nice how your hips are shaped!” he pointed out, “And the way you kept lifting y-your tail. You were doing that so I could see you?”

Mutely nodding, Heart wondered if dying of blushing was why she wasn’t supposed to be friends with colts.

“I… I really liked your pictures,” he replied. “I really like your… um… your… fillyhood.”

“It’s… it’s not much really,” she said so nonchalantly, “It’s just this little pocket except uh…”

Eyeing her, the colt asked, “Is this one of those sentences you don’t wanna finish?”

“Well it’s just… kind of gross,” she said with a blush. “I mean, maybe you have the same thing, but it just… surprised me I guess. And it’s… I mean… I’m… pink.”

“You mean your hair?” he asked, looking at her mane, “More of a magenta, really.”

“No, I mean… my fillyhood does weird… it opens, and… stuff,” she said, squirming as that strange urge rose in her from back there again. “And it’s pink inside, and… wet. A-and that’s totally gross, so I didn’t want to say and—”

“No, it’s okay! I just… I didn’t know,” he says, “It just looks pretty, and you… don’t have any balls.”

At her blink, he clarified, “It’s like what you don’t have down there’s special. You don’t have any balls, or a penis, just your… fillyhood. Your belly’s really… round, I mean. Just smooth and c-curvy.”

“I… I suppose,” she admitted, “But what I really wanna know is uh…”

“…is this one of those—”

“I don’t have a penis!” she blurted out. Blushing, she said more casually, “So I sort of don’t… know what they… are. It’s a… thing that comes out of you. Down there.”

“Yeah?” he replied, as if it were obvious.

“That’s all I know!” she fussed, “I don’t know anything more than that, and your penis is supposed to go in my uh…” before he could speak, she clarified, “vagina.”

“What’s a vagina?” he asked.

“I dunno, exactly,” she said in equal confusion, “B-but that stuff down there, where I don’t have balls, is a… vagina I guess.”

“Oh,” he said distantly. “And my penis is supposed go into it?”

“It’s weird and maybe my friend was joking,” Heart said nervously, feeling really good about putting something into it right now. “She was kind of serious though, and she’s h-having a baby.”

“Huh?” he asked, “She’s a mare, then?”

“No, she’s only a year older than me!” Heart protested, “So like, I could have a baby, like right now even. So I can’t put your penis in my… vagina.”

“What’s that got to do with having babies?” he said in confusion.

“Apparently that’s what makes it start,” she replied, “My friend got a penis in her vagina, and… now she’s got a foal in her belly. It’s… getting kind of big, too.”

“So… you don’t wanna penis in your vagina,” he queried.

“No!” she replied in flustration, “I mean, yes, maybe. But I’m just a filly! What if I… I mean how would I even get a foal in my belly? I mean… would I just take my foal to class? I’ve never heard of a filly being a mommy before! S-so I can’t… put your penis in my vagina, even though I want to t-try.”

“Well, okay I don’t see a problem with that,” he said frankly, “So I just don’t put my penis in your vagina, and that’ll be fine.”

“Y-yeah,” Heart offered mutely. “I just… was curious. About what a penis is.”

“Well it’s a thing that comes outta me,” he offered, “And it’s how I pee.”

“C-could I see it?” she asked, a terrible thrill rising in her nethers.

He looked at her incredulously, “Now? Here? I can’t just pee right here!”

“O-oh, right,” she replied, abashed, “So you have to go pretty soon.”

“Yeah, I need to fly,” he replied, “We could meet… later though?”

At her look of surprise, he suggested,

“Let’s make a playdate ourselves. We can meet together, and be friends, and… I guess just meet out in the woods somewhere, like behind the school?”

“Why out there?” she asked.

“It’d be private, and um… I could… pee without having to go to the restroom,” he mumbled, “S-so you could see, unless you wanted to try to go into the colt’s restroom—”

“Woods is fine!” she squeaked. Her friends would never ever ever ever let her live it down if she got caught in the colt’s restroom! Is…

Is that why they didn’t want her to see colts peeing?

“Well I could be free this weekend, on the afternoon,” he said, “You wanna meet me behind the school? We’ll find a hiding place from there, and… stuff.”

“Okay,” she said faintly, “Just a… playdate then. And you can’t tell your parents, or anyone, or they might try to… stop us.”

“Got it,” he said with a smile, “So I better hurry, so they don’t ask what took me so long. You better find your parents quick too.”

“Oh! Yes, I… I have to hurry!” she said, rearing up and charging off. Above her, a blue and gold pegasus winged his way home.

She uneasily looked around. The woods behind the school had lots of trails, and it wasn’t fenced off or anything, but Heart Mender had never gone to school to play outside. It was kind of… weirdly quiet, with no foals around.

There was a camera flash behind her.

Turning, Heart Mender saw the colt standing there with a camera on his neck. “Sorry,” he whispered, trotting up, “I didn’t know a quiet way to get your attention.”

“Let’s just get outta sight,” she replied, heading into the woods. They explored the trails somewhat, but mostly they just picked a spot out of sight of the entry, a trail behind some bushes that didn’t look too walked upon.

“Okay, so now you wanna see me pee?” he asked.

Blushing, Heart Mender forgot about that. “Well, yeah, I mean,” she prevaricated, “I really just wanted to see your penis.”

“Okay, well it comes out when I pee, so I’ll just… show you that, okay?” he said.

She nodded, blushing.

From his groin came a skinny little thing, that quickly extended in length, from where his balls were. It was orange as he was, but mottled with pink, the pink of her insides, with a flat tip, and a weird ring in the middle. She stared, captivated, when a stream of urine started to trickle out of its tip.

The strong smell of urine started to fill the area, as the colt continued to pee, saying, “So that’s… my penis. Um… yeah.”

There was something… dizzying about the scent as he did it. She wasn’t sure she liked it, but it was… intriguing, in a smelly way. The stream trickled off in his penis, and then it just flexed upward, then bobbed a couple times.

“Oh, it’s… moving?” she asked uncertainly.

“I’m just s-shaking off the pee,” he replied, “I can move it a little, see?”

The penis jerked up again, then bobbed back down.

“Wow, that’s really neat,” she said, as to her dismay the penis just started sliding back into his groin. “It’s not nearly that easy when I pee.”

The colt swallowed, then asked, “C-can I see you pee, too?”

“Me?” Heart said, looking at him in surprise. “I don’t have a penis though. It just sort of comes out!”

“Out of your… pocket?” he said curiously.

“I’ll… I’ll show you,” she said blushing, “Because you showed me I mean, but it’s really nothing special.”

It didn’t seem like nothing special. Far from embarassed, Heart Mender was strangely giddy with the weirdness of just… peeing in front of a colt. He stood behind her, so he could see better, since she clearly didn’t have a penis that came out, that you could see from the side. “S-so um…” she said, lifting her magenta tail, “Here I go.”

And now she actually had to pee. She concentrated a moment, and the pee welled up inside her, then just… sprayed out, like it always does. But it felt… different that a colt saw it. Better, somehow. Her pee turned into sort of a stream too as she flexed her… fillyhood to get it out of her better. There was a camera flash.

Blushing and looking behind her, Heart saw him with his mouth on the camera trigger. She couldn’t just stop peeing! “What are you doing?” she asked, continuing to empty her bladder as he took a second picture, briefly blinding her with the flash.

“Your uh… fillyhood is really pretty,” he replied uncertainly, eyes losing focus as he inhaled through his nose. “Even when it’s… peeing.”

“Y-you’re smelling it…” she said in a tiny voice. “It’s really… smelly.”

“I don’t mind,” he replied eagerly, “I think it’s neat!”

Her pee had stuttered to a halt in the wake of the camera flashes, so emboldened by his words she said, “Okay, I’m gonna finish then. Um…” Pee streamed out of her. “…yeah.”

“Your fillyhood moves” the colt replied, captivated by her peeing butt.

“I-it makes peeing easier,” she said uncertainly, “I’m gonna… nhf” the rate of urine increased, until she was pushing it out as fast as she could, making a mess of the plants off to the side of the trail. “Pretty…” she grunted, “Neat, huh?”

“Yeah…” he said, watching until every single drop was out.

They left the peed area, until it wasn’t smelling anymore. “I… lifted my tail for you when you were taking pictures,” Heart said in the wake of… whatever it is that they just did. “I’d have… moved my fillyhood for you, if I thought about it. It kind of… moves on its own really. S-so your…” she stared at the soft looking penis hanging between his legs, “Penis is lots cooler. How does it… come out of you?”

Blinking as though disoriented, he focused on her saying, “I just… push it. I mean, it sort of moves on its own too. Only comes out when I pee.”

“What about now?” she asked mutely.

“Now?” he replied, “What do you… oh.” Looking between his legs, the colt observed his own erection passively. “I um… can’t pee anymore,” he concluded, looking up at her. “I’m all empty, so I dunno why it c-came out.”

“It looks really… soft,” she said pensively.

“You wanna… touch it?” he asked, penis bobbing at the thought.

“Could I?” she asked, looking at him in surprise. He nodded, so she added, “A-and you can touch my fillyhood, too. If you wanna that is.”

She leaned forward to nose at the shaft between his legs. It twitched soon as her nose hit it, and down between his legs was a strangely familiar spicy scent that didn’t smell like urine at all. It was so soft against her nose. Another urge rose in her enough to make her gasp as a hoof came in contact with her labia.

“Wow, you’re really soft,” he said in awe, continuing to feel around at her under there.

“You’re soft too,” she insisted, “Just like… smooth, but kind of hard. Y-your penis smells really good.”

A pause and he said, “Oh Celestia, your fillyhood smells awesome!”

“Not like pee?” she hoped.

“Not at all!” he said, “Like spicy… tart… something.”

“Yours smells really…dark,” she replied, nosing in as his own nose bumped her labia. Luckily, the larger colt could reach around the compact filly somewhat. “And also spicy.” She wanted to… she licked his penis, just to—

“Woah!” he declared, scooting away as his penis flexed strongly. “Were you licking it?”

“It smells good!” she protested, “Not like pee at all! I didn’t mean to hurt you!”

“No, you didn’t, it felt really good,” he said, moving his flank back in her reach. “Y-you can lick it as much as you want.”

Wide-eyed, Heart took in his spicy scent again, and cautiously, then curiously slid her tongue along his shaft. It was like velvet skin, with a strange, stiff core beneath it. She explored the tip—

And was immediately interrupted when the colt’s own tongue slid within her labia, and stroked her everything back there.

“T-that feels good too!” she squeaked, hardly even beginning to describe the novel, soft, wet sensation of his hot tongue stroking her in there. He didn’t even pause, so she went back to his penis, licking it, and mouthing along it, trying to make him feel as good as he was making her feel. She didn’t even know if it was working, but she didn’t even care about the pee anymore. She boldly explored the tip, poking her tongue into that little hole at the end. It made her want things.

“I… I…” she said, backing up from his penis, and escaping his tongue, because she needed something her friend hinted about. “I think you s-should put your penis inside me,” she said, turning her rear fully his way, and moving her tail out of the way of her fillyhood. “I wanna f-feel it. What it’s like.”

“Are you kidding?” he said, breathing heavily, “There’s no way it’ll fit!”

“Just… try, please?” she whined.

He looked at her hungrily, but then said, “I don’t… wanna put a foal in your belly. You said that’d happen.”

“Oh, just do it,” she fussed, stomping her hoof.

“You don’t wanna be a mommy though, do ya?” he asked.

Heart didn’t want to. She knew it would cause so much trouble. She couldn’t even imagine what her parents would think, much less her friends. She winked, hard.

“Yes, I… I wanna,” she gasped out, “It… it takes forever anyway, so just… p-put it in me now, and I’ll have all year before anypony knows.”

“B-but then it’ll be a year, and…” he said weakly, then marched up to her, putting a hoof on her rump. Heart’s legs immediately stiffened, as he asked, “H-how do I get it in?”

“I… I… I don’t know,” she said in surprise, a disappointment rising in her like nothing ever before. Turning to look at him, Heart said, “I just really wanna t-try it. I think if I lay down maybe…”

“On the ground?” he asked unhappily.

Fidgeting, Heart Mender said, “N-no, on my bed.”

Sneaking into her house, Heart saw her parents were still out shopping. Good. She went to her room, and opened the window. Into it, flew the colt. He climbed in and stood there, while she danced excited on her hooves. “Spice Tassel’s belly’s really stiff and getting bigger,” she said, “Because there’s a foal in it. That’s what I’m gonna do next year.”

“Are… are you sure?” he asked. She looked down, and his penis was sliding out again.

“I want… to feel it, just a little,” she replied. “Just put it… um… in me and I’ll… figure out what to do after.”

“I really want it too,” he said longingly, “I dunno just… your fillyhood’s so pretty. Is my penis really supposed to go in there?”

“Let’s find out,” she replied. Laying on her bed, she was gratified to see the colt trot right up to it. Spreading her legs, her fillyhood kind of… winked upside down there. “Okay, just… put it in,” she said excitedly, “And… and rub it around in my… vagina.”

He reared up, planting his hips to either side of her, and hunching over her, brought his penis to bear. “So I just…” he said, and bliss touched her labia. “Oh…” he said, pushing his penis more firmly into her petals.

“I’m… h-having a foal now, I guess,” she said anxiously, “H-how’s it feel?”

“S-softer than anything, and really warm,” he said, hunting around with that penis inside her tingling lips.

“I can’t believe just doing this makes a foal in your belly,” Heart Mender griped, feeling dissatisfied, and wanting him to press against her vagina more firmly. “Push… harder, a little,” she asked, and he did, and…

He slid into her, right up to his balls.

They stared at each other in shock.

“Your vagina’s… really deep,” he said faintly.

“I… I guess it is…” she murmured, staring at the… the colt. It didn’t look like he even had a penis, because that entire orange length was just… stretching her immensely, so deep inside.

With a gorgeous sliding sensation, he pulled out from deep within her, then pushed back in again. Then he did it again. And again. Then her mind took a vacation to a tropical island, because he just… fell into a steady, repeated rhythm of thrusting, the sliding ramping up her pleasure to dizzying heights. She couldn’t feel anxious now. She was too… fillyhoody! She just gasped gratefully, as all she could think about was that sliding tingling bigger and bigger and…!

“W…what?” she asked breathlessly as her pupils narrowed her body laid back and filled with his steady, inexorable thrusts. Then she realized she’d been squeezing around him, when everything just started rippling down there. “Hah… ahh!” she gasped, as rushes of immense pleasure flowed from her groin, like waves crashing inside her. She writhed in place, and he lost it on the out thrust, slipping out of her as she twisted on the bed, trying to move, trying to deal with… what was happening to her?!

She’d never felt anything like this before in her life. She was seeing stars. She felt like a hug was exploding within her. And he grabbed her hind leg in his forehooves, and pulled her right back onto his penis. As she felt herself fill with him again, she became aware that those strange rhythmic clenches inside her hadn’t ceased, and her pleasure surged as once again she could clench around a penis.

It slowed at last, but the feeling just sang through her, and he wouldn’t stop thrusting, so it wasn’t going away! “Love… so… much…” she moaned, as the stallion pulled himself into her again and again. Her pelvis was so stuffed, and stretched, and she didn’t have a penis, or balls. He just pushed his penis so the base of it was right up against her, and the rest of it was inside. She watched in ectasy the place between her legs just taking that penis, just the perfect shape for his earnest thrusts. His hips moved powerfully. He was a machine, a fillyhood sliding filling machine, using his penis to push deep. His eyes were scrunched shut, only one thing on his mind, and all she could think was how incredible this felt.

He stopped at last, pushing deep and holding her groin tightly, tensely against his. She tried to think of how to thank him, when suddenly something… happened inside her. She stared off into space in vague wonder, feeling something squirt up into her, even deeper than his penis was. Then again, and again. It just kept pumping up into her, in the same rhythm that his penis was jerking strongly against her. That hole in the tip, it was… pushed right against her in there, where something was leaping out of it and sliming madly on places within her she didn’t even know existed.

So she just breathed, and smiled, and… enjoyed this strangely satisfying liquid pumping thing his penis was doing. He didn’t have more pee already, did he? Why did it feel so good to have him pee in there? What was he putting in there, if not pee? Deep into her belly, something that was changing her, making her feel… supremely content.

She did that with him every time they could after that. She loved the feeling of being filled. He’d sneak into her room, or they’d hide in the woods, and learn how to do it pony style, or in a shed nopony was using, or whatever. She loved that incredible squeezy tingly that she had to do, she loved the thick penis sliding inside her, and she loved the satisfying pumping firing up deep into her belly.

“I dunno why it’s so good,” she said to him in her room once, stroking her belly with a hoof, “I just love you putting it into me. Right here, in my belly~”

“That’s… that’s where Spice has her foal,” the colt pointed out. Heart Tender shivered at that, staring at her belly in terrified wonder, murmuring,

“Your… your stuff must be putting a foal into me.”

…

“He… he’s doing it cutie! I’m… he’s putting you inside me!”

…

“I don’t care if I have a foal yet or not. Just keep putting that foal stuff into my belly.”

…

“Ugh, I feel… weird. All day I’ve just been… weird.”

…

“M…m… maybe you… have to put a… whole foal’s worth… of your goo in me.”

…

“She… had the foal. They… they took her outta school. I dunno if I’m gonna see her again.”

…

“I don’t wanna get kicked outta school. My… my belly’s already getting big! What are we gonna do?”

…

“Nopony suspects yet. Maybe I can just… finish the foal in secret.”

…

“That’s my friend, Tinker. He put you in me! Hee, she really likes to move in there. Your foal in me.”

…

“Tinker! I… I’ve been feeling all squeezy all day, and it… it’s just getting stronger! I don’t know what’s happening, I think something might be wrong with the foal!”

…

“That… last one was… weird. It’s just… stretching me in there. I don’t want to do it, it just keeps building up. What am I gonna do, Tinker?”

…

“Uhn no I… I don’t wanna eat, I just wanna squeeze. I wanna.. uhn… my… fillyhood feels strange.”

…

“Augh! It’s… it’s splitting me apart! I–I can’t! Oh Celestia what’s…”

“It’s a foal! Your foal’s coming out of you! I saw it, then it went back in.”

“S…seriously… I thought something was… was wrong.”

“I dunno. Just… you have to get the foal out of you somehow, right?”

“Ugh, then I’m gonna… I’m gonna try to.”
