Chasing each other through the bright, sunlit woods, an orange unicorn filly with blue eyes galloped along while her brother, a brown pegasus in every way, flew up behind her.

“No fair, Pound!” Pumpkin Cake declared in a hurt tone, “No flying! I can’t fly!”

“So?” he said, as he caught up to her, “I can’t run as fast. What’s wrong with being different?”

“Oh brother,” the filly groaned, “We’re not even at the creek. I can’t cross the creek very fast!”

“I’ll see you on the other side then, Pumpkin!” Pound said unrepentantly, and buzzed on past her.

Pumpkin Cake was blushing furiously, but at the same time she knew her brother didn’t mean any harm. It wasn’t so important to catch each other in this game, but just have fun running, and they were gonna get to that meadow they found the other day, where they could roll around, and have a snack, and laze around in the sun together.

Reaching the creek, Pumpkin didn’t even try to scale down the steep bank. She just concentrated on the rushing feeling of magic around her horn, brighter and brighter until she felt it catch the other side of the creek and she pulled. Winking out, Pumpkin winked back in on the opposite bank, and continued running through the shady forest.

“What took you so long, Pumpkin?” Pound Cake was saying smugly, waiting for her as she got there.

“Ooh, you cheated!” she retorted, getting up nose to nose, “I would have won if you didn’t fly!”

“Hey, it’s okay!” he replied, shrinking back with a sheepish grin, “I was just playing around. You can win this time. I really just like flying places. If you had wings, you’d know how fun they were!”

“Well I don’t,” the orange filly said, strutting past him into the meadow somewhat mollified, “But I do think having a horn is cool, so I’d probably like wings as much as you do, if I was a featherbrain!”

“Hey!” he argued, trotting after her, “You just don’t know how fun they are. Isn’t it really cool if we’re different?”

“What do you mean?” Pumpkin asked, looking back at her brother.

“When you light your horn you get a… you said it feels… like your magic rushes around it?” he prompted curiously.

“Yeah, sorta,” she said with a cautious hoof lift.

“I just think that’s really cool! Seeing you feel your magic, it’s just something that makes you special,” he replied, “So I like seeing you feel it, even if I can’t do magic.”

Lighting up her horn again with a slight giggle, she said, “Like this? It’s nothing special.”

“Try to pick something up!” he suggested, “Pick up that branch over there.”

Pumpkin levitated it, and Pound declared, “See? You looked at the branch and you made your horn a little brighter, and that stuff is just normal for you. Can you feel your magic when it wraps around the branch?”

“Y-yeah?” Pumpkin said, looking self-consciously at the branch floating in her sparkling blue magical aura, “It’s nothing special just any unicorn can do it.”

“Well, just…” Pound fluttered up to the branch, hovering there indecisively, and pushed at it with his hoof.

“Hey!” Pumpkin protested, as her magic tugged aside, reflexively pushing back against his hoof.

“See, you can feel me with your magic!” he declared excitedly, “I can touch this branch, and you’ll feel it, because you’re a unicorn. It’s so cool that I can do that! See?”

Pumpkin blushed despite herself, as she felt Pound booping her branch to bob back and forth in the air, saying, “Yeah, I can feel it, and that’s kinda cool I guess. You can fly, though!”

“Well, yeah,” Pound said matter-of-factly, descending to the ground beside the stick, “I never said I was not cool. But no matter if I want to, I can’t feel your feathers, because you don’t have any! You can feel mine though, any time you want, and all I have to do is…” Pound extended one of his little wings out beside himself.

Trotting up to her and presenting that wing more encouragingly, he said, “See, so that means there’s things that you can do, that I can’t do, because I’m a pegasus! Just like I can touch your magic, because you’re a unicorn.”

“So, so you want me to preen your wings, I guess?” Pumpkin asked cautiously.

Blushing, Pound Cake half folded his wing and said, “Well I wouldn’t mind. You are really good at it. And you can use your magic for that, too.”

The two looked at each other for a pensive moment, then Pumpkin took the final steps to him saying, “Oh okay, come here you big baby.”

He just grinned at that and sat on his haunches, extending his wing so his sister could nibble on it. She also used her magic to help sort out any of his misaligned or mussed up feathers, but mostly she carefully tugged them into place with the supple lips of her mouth. It always made him feel closer to her when Pumpkin would do this, as close as they are already. He sighed happily as she gently nibbled on the upper part of his wing, licking the light brown fuzz just like he liked it.

“I could use just my magic,” Pumpkin said thoughtfully as she became satisfied with his wings, “But I like using my mouth, because you taste really… soft and warm. Especially the top of your wing.”

“Y-yeah,” he said, with a blush at the sensitivity of his folding wings from her minstrations, “I wish you could feel that, but you can’t because we’re different.”

“Yeah…” she said, looking at her brother with a less than satisfied expression.

“You okay?” he asked with concern.

“I was just thinking how we’re different,” she said, “You’re a colt and I’m a filly. So it’s not just unicorn and pegasus. You’re also brown and I’m orange, though those are almost the same color.”

Blushing, Pound Cake said, “It’s weird how colts and fillies are different.”

Looking at him chidingly, Pumpkin said, “It’s so a stallion can put a baby in a mare’s tummy.”

“Yeah, r-right,” he agreed, looking away shyly. Pumpkin… looked between his legs, but with him squatted on his haunches in the meadow here, she couldn’t see anything. Did mares really… want that stuff? Did stallions want Pumpkin’s fillyhood? She couldn’t imagine they did, but she wasn’t supposed to feel what they felt. She guessed that her brother felt the same as she did, just… not sure of how he felt about her fillyhood, the same way she was unsure of how she felt about his colthood. But… he was right. They were different. Maybe he didn’t even… want it like stallions were supposed to.

“Have you ever wanted to do that?” Pumpkin asked in a nervous voice. Surprisingly nervous, because she trusted her brother with anything. But if he was a colt, then…

“What?” he replied, looking back to her in confusion.

“You’re a stallion, right?” Pumpkin asked the brown colt.

“Y-yeah?” he said, tilting his head in confusion.

“And you remember that Miss Cheerilee said,” she continued, “That stallions feel like mounting mares and… putting their thingy into them. Do you ever… feel like that, with your thingy?”

A pause and he asked, “You mean my boy thingy, right?”

“Yeah your… your (penis).” Pumpkin whispered that last word, despite them being far out of range of anypony to hear them.

“Well, you’re a mare,” he replied cautiously, “Do you ever feel like… getting mounted, and moving aside your tail like you’re not supposed to?”

“Well, no, but,” Pumpkin said in frustration, “But I’m curious. I mean I’m still a foal so I’m not really a mare yet. So it’s not like I’ve actually ever done it before. I don’t know why mares just do it for estrus. It seems weird to point your butt at somepony, and just let them mount you. But I have… thought about it before. What it would be like to get… mounted.”

She wanted to tell him how fascinated she was with her entrance back there, the idea that deep within was a womb where a foal could mature, once she was old enough at least, and then she could just… push her foal out of her fillyhood? But all she told him was her thoughts about getting mounted and what it’d be like.

“Well I… think about it sometimes,” he reluctantly admitted, “I’m just supposed to… climb on your butt, and put my penis in? I guess I could do that in theory, but I never… you know… tried.”

“Would you like to try?” she asked feeling a stirring within her at the thrill of what she was saying.

“With… you, right?” he asked uncertainly.

Pumpkin just blushed to silence at that, feeling strangely disappointed, even though she wasn’t trying to do anything with him in the first place, not for real.

“It’s okay if you want to do it,” Pound assured her, “You’re supposed to want it someday at least. I never thought about it, but maybe I’d… want it too.”

“You would?” she asked, looking hopefully into his brown eyes again.

They gazed at each other, until he said, “Can I… can I touch your fillyhood?”

She blinked, not expecting that persay.

“I never wanted to mount anypony, but I’m curious too,” he said, “They said we can never touch a filly there, so I’ve never… gotten to touch there.”

“You mean with your hoof?” she asked with a slight wince at the though.

“No, just my mouth,” he replied hopefully, “I just want to see if it opens and if I can see your… see into um… you.”

“…I kind of want to see that myself,” she said honestly, “You’re lucky you’re a colt. Everything you have is right out there outside. I look at my butt and I just see… a slit, and there’s supposed to be all that… stuff inside that colts love, but it just seems like a slit to me. I don’t even know how to wink.”

A thought and she added, “Wink my fillyhood, I mean. Like mares do.”

“So you’re gonna let me touch you?” he asked warily.

“Sure!” Pumpkin said, trying to be all confident about it. Standing up and turning her rear, she said, “You can touch it all you want. I trust you. Can I touch your…”

She almost trailed off but then blushed and blurted out, “Penis?”

“Sure, any time,” he said with equal conviction, and a lot of interest in her butt, “It’s just like how you can use my wings. I just wanna… feel your fillyhood, so I can see what it’s like to have one.”

“I… I don’t even know what it’s really called,” Pumpkin said nervously, her big orange tail still in the way, “Miss Cheerilee just had words for all the different parts like labia and vagina and stuff.”

“Well, whatever it’s called, I think it’s cool,” he told her, “I just don’t have one, so I need to borrow yours um… you know.”

“Yeah, yeah, I know,” she said blushing despite herself, and the orange unicorn filly moved her tail aside, exposing herself to him. “W-well?” she asked with a nervous smile, looking back, “Pretty cool, huh? I sure am a… filly.”

“It is cool!” Pound said, looking at her butt, “Your belly’s all round and just goes right up to the slit. I’ve got balls in the way of mine.”

“Right, balls, where you make the stuff that goes into fillies,” Pumpkin prompted, resisting covering herself up again, “And puts babies into them.”

Blushing harder she added, “A-and puts babies into me.”

“Don’t worry, Pumpkin,” he assured her, “I’m not even thinking about doing the stallion thing and putting a baby into you. Our parents would kill us! I just wanna…you know, feel it, a little. And you could tell me what it feels like for you.”

“Okay, kn-knock yourself out,” Pumpkin said, bracing her hind legs on the grassy ground. When he did put his head back there, Pumpkin sucked in a breath at the feeling of something pressing up against her back there, and dragging along her sensitive labia.

“You okay?” he asked from behind her, “That wasn’t bad, was it?”

“No, just surprising!” she said, looking back at him, “It’s really sensitive.”

“I’ll be careful then,” he replied confidently, “And no hooves.”

She nodded, facing forward again, and that hot slick presence was against her once more, pressing with surprising force. It made her shiver all over, like there was an itch growing in her loins, that his attentions weren’t quite reaching.

“Wow,” Pound said in awe, pausing in his minstrations, “Pumpkin, did you know you smell really good back here?”

“I do?” she asked, looking back in confusion.

“Maybe it’s a colt thing,” he said sheepishly, “But your fillyhood just smells really spicy and… like your normal scent, but with this cool spicy treat smell. It doesn’t taste good though.”

Blushing, Pumpkin squawked, “Taste good?!”

“Oh, yes I um… started licking, just to see if it tasted good,” he said, “It didn’t taste like anything though. But it was really soft! Your fillyhood’s kind of like my… the place where my balls are. That’s what it feels like. Really soft and warm. I uh… I’m gonna try opening it, but I need to like… spread it somehow, and…”

“Go ahead and use your hooves,” she allowed him, “Just don’t touch right in the middle. I don’t know if that would feel good.”

She felt him push on either one of her buttcheeks, and a weird whooshy stretchy feeling between them. “I-it opened,” Pound Cake said in shock, “It’s really pink.”

“Pink?” Pumpkin asked uncertainly.

“Yeah! It’s like your… it’s like your mouth, but down here, but it’s really tiny actually!” Pound said, nosing at Pumpkins’… something. “I don’t know how I’d ever fit my penis into there.”

“Maybe you should try and find out,” she murmured, staring forward and rocking in place a little.

He didn’t seem to hear her, so she said louder, “You can use your tongue again! I liked that!”

“Oh, right! So how does it feel?” he asked, then she felt his tongue slide right into her… place.

“I don’t really know what’s back there!” she said with a blush, “I need a mirror or something. I feel your tongue sliding on… things. And there’s this tingly itch d-deeper underneath it. And I feel like I’m getting goosebumps, like prickly like… I don’t know.”

He didn’t respond, nor did she want him to, so soon she was rocking there, dull eyed, saying, “It’s… making me out of breath? I-I don’t know why I’m rocking. My hind legs feel stiff. They keep tensing up. You’re… you’re licking… all around in me!” Pumpkin Cake was trying to keep him up to date as much as possible, because she was afraid if she fell silent, then he’d stop. But eventually she ran out of things to say, and he stopped making her butt tingle more and more, and she wanted it.

“I… I want to mount you now,” he said in disbelief.

“W-what?” Pumpkin said, looking back with disappointment in her loins, and confusion on her face.

“It’s making me think about it, licking your fillyhood,” he said, “And the smell is really… and my penis started c-coming out on its own.”

“It did?” she asked curiously, her legs uncharacteristically stiff as she rounded to look under him.

“It usually only comes out when I pee,” he said nervously, “But I guess it’s coming out because I’m a… stallion, about to put a baby in a mare.”

“I-it’s really… just hanging there,” Pumpkin said in awe, captivated by the dark, swinging member, “It just comes out of you?”

“Well… well yeah,” he said, “Can I lick you more. I’m not gonna put a foal in you but I just want to lick more a-and…”

“Can I lick you?“ Pumpkin asked hungrily.

“Oh, yeah!” he said, turning and presenting for her, “You can lick whatever you want.”

Heading up to his backside, Pumpkin could see his plump little balls hanging there in a soft sac beneath his puckered anus, as he turned his short tail aside to show her. When she licked his balls, he grunted in surprise, but didn’t protest. The sac was desperately soft, just like Pumpkin’s fillyhood, but the two hard things inside moved around under her tongue. “I can’t get to your penis,” she complained, sticking her nose between his pelvis and his hind legs.

“Uhm… hold on,” he said, and Pound Cake lay on the grass, rolling onto his back, smiling up at her, “There, now you can lick it!”

He could also see her while she was licking it. “You don’t… mind?” Pumpkin asked warily, sidling up to his half erect member.

Shaking his head, Pound said, “No problem,” giving that dick a few pokes with his hoof, “A penis is pretty sturdy actually.”

“No I mean… you can see me,” Pumpkin said anxiously, “You want to see me just… licking your penis?”

Wide-eyed, Pound said, “Wow. I can see you. Pumpkin, I can’t see you preening my wings. Not really. They’re behind me! I–I really want to see you when you do it, so go ahead and do it to my penis. Thanks it’s just… really cool that I can see you doing it. Y-you can even use your magic but be careful.”

“Okay, but I won’t do anything stupid,” Pumpkin said shyly. Nosing at his groin, she gave his member a cautious lick. Then she looked up at him.

“It felt really good!” Pound assured her, “Go ahead and do whatever you want.”

Licking again, then more strongly, Pumpkin found, “It (lick) doesn’t taste like anything, but (lick) your penis smells really good too! (liiiick) I know what you mean by spicy.”

“I-it’s making me feel funny,” he said laying a forehoof along behind her bountiful orange mane, as Pumpkin looked up at him and dragged her tongue all along his stiffening member, “I’m… I’m breathing harder too, and… and I feel that itch d-deeper inside.”

“You want me to… lick down at the bottom?” Pumpkin asked, going down to swirl her tongue around where his penis became his scrotum.

“No, no, lick at the top, the very top,” he said eagerly.

Pumpkin did and Pound outright bucked his hips up against her at the touch of her tongue. She looked up at him in alarm, and he said in dissheveled surprise, “I didn’t think it would feel that good! Yes, only lick the tip, that’s perfect,” he told her.

So Pumpkin did. She felt all… melty between her legs, with her brother’s musk flooding her sinuses. She licked all along the tip of his member, now strainingly erect, sliding her tongue around the edge of the flat head, poking her tongue curiously at the hole in the tip, and even putting the whole thing in her mouth. Luckily in this position, his penis was almost sideways so when he bucked up it just jerked his shaft sideways in her mouth, rather than jamming down her throat. So she sucked on the tip, and used her magic to explore the rest of his penis, a very interesting feeling as she slid around and slightly levitated each of his balls. His jerky movements turned into a steady thrusting as he panted there more and more urgently, laid back on the meadow.

“Can… can I lick you again?!” he cried out at a volume that startled her. Pumpkin looked up at Pound, the tip of his dick still held in her mouth, and he stopped bucking his hips underneath her. “It… it feels so good,” Pound said emotionally, “Your mouth is so hot and wet. I–I just want to lick you some more, that’s all. Oh I… I love my penis being in you like that. B-but please, let me…lick you some.”

Pulling off of his penis with a squilch, Pumpkin said, “Maybe if I lie on top of you then you can lick me, while I lick—”

“N-no!” Pound said nervously, “I just want to lick you like you were standing before, it’s okay.”

“Okay then,” Pumpkin said, slit-eyed as she stood and turned tail to him, “Better get licking my fillyhood!” she said with a teasing sway of her hips, “It’s really tickly for you!”

He did, and Pumpkin gave a shocked moan at the feel of his tongue strongly pressing against her, shocked that it would feel this intense, even more than before. It had been building up the longer she licked him, wanting to be licked more and more, and now Pumpkin blushed, and needily pushed her butt back against her brother’s face, trying to get him deeper.

“Oh… yes… lick me, I need you… in… I need you innn!” Pumpkin whined, desperately trying to sit on his snout or something.

Then Pound Cake stopped licking, and Pumpkin looked back long enough to say, “Wha—” before her brother was climbing up on her rump. Pumpkin had to stare forward at a desire rushing up in her, as his weight came down on her. Why were her flanks so tingly?! His forelegs slid right up against them and squeezed around her barrel.

“I’m gonna… put a foal in you,” Pound Cake told Pumpkin breathlessly, and something smacked against her belly. That was his penis! “Sorry, I… I need to. I’m gonna make your belly big, just like a… a… a mommy.” His penis smacked her belly again, and dragged along it right up to her vulva, and Pumpkin Cake didn’t object at all.

“You’re… you’re doing it!” she declared in full body arousal, even her ears tingling, as she felt his penis push up against her fillyhood, “B-but your penis can’t fit in!”

“I’ll just put the… the tip in,” he said desperately, his penis dropping from its target, then lifting up again to push into her, “The hole’s in the tip. I… they said stuff comes out of my penis! I want it in your fillyhood when it comes out… oh it’s so warm…”

“You’re doing it,” Pumpkin moaned indulgently, pushing back against him as he pushed forward. He slid all the way into her, his whole tip and Pumpkin squeaked as his penis stretched her wide. Then moaned at the aching stretch. Then a loud squeal burst out of her as the colt hugging her flanks started sliding even deeper inside!

“H-how far do you go in?!” Pound asked frantically, half penetrating his sister’s vagina, as she stood under his weight, panting, looking back, but only able to feel, not see behind her.

“I-I don’t know!” she said anxiously, “Your penis is stretching me! I-it feels so good!”

“I’m gonna go as deep as I can,” Pound said indulgently, his chest leaning on her butt, and his forelegs tightening as they hooked on her thighs.

“It’s going… it’s going… it’s going…!” Pumpkin announced at the glorious slippery sliding penis in there. Was she gonna be a mommy?! Her… her belly? Pumpkin looked underneath herself as Pound started pulling out, and pushing in and pulling out, at her slim belly that had a penis inside it right now. A boy inside it. That belly was gonna get big and round?

“You’re gonna put a foal in me,” Pumpkin moaned, standing up straight, and shoving back, to match his thrusts. That was all she thought about from then. Sweat dripped down their sides as the two foals singlemindedly thrust together, getting ready to impregnate Pumpkin Cake one way or the other. The scuffed grass was just a distraction, the bright sunlight a pleasant warmth to aid in her task, and the only sounds the urgent huffing and thrusting and wet noises as Pumpkin’s dripping vagina took every inch of Pound’s penis again and again.

Her brother felt like he was expanding in her near the end. He shoved deep, and then ballooned outward, groaning as he did, stretching her deepest parts to their limit. “Are you gonna do it?!” she asked in disbelief, looking back at the colt whose face was scrunched up in urgent need.

“I… I think so,” he said tensely, thrusting in her, until he flared again. She stared in amazement as her brother humped her own hips so meaningfully, feel him slide in her and in her and in her, where he was going to put a baby in her. His gasps grew more and more urgent, his eyes becoming dull as he stared forward, his final flare the biggest of all.

Pound stopped thrusting again, so Pumpkin asked, “Are you gonna—” something hot and slimy squirted into her, spraying against her in there. Pumpkin Cake stared back at her hips, scared and hungry, and relieved. At his hips, that were pushed up against hers, she felt her brother’s penis ejaculating inside her. She panted, tongue lolling out, every time Pound Cake’s penis just jerk, jerk, jerked in there. Hot spurts of what must have been his seed pumped up into her. Doing things to her.

“Pound Cake!” Pumpkin declared shrilly, “You’re putting your… you’re so deep you’re ah ah ah—” and then Pumpkin jerked in place herself as her passage started clamping down around Pound Cake’s penis all on its own. She couldn’t stop doing it! Pleasure exploded in her every time. It felt like her blood was electrified. She couldn’t even think about the seed pumping into her, the penis which stilled within her, its urgent delivery complete. She felt… almost frightened if she didn’t feel so good, that powerful movement within her making her whole body jerk spasmodically, except for her hind legs which were utterly stiff and locked in place.

Impregnated, finished, Pumpkin still pawed at the ground with a foreleg, and even though her vagina was still she was tingling and gasping and shaking still, because his seed, and her whole body wouldn’t stop tingling, and she kind of lost track of anything and anypony at that point. Pumpkin Cake did however feel it when her brother pulled his penis out of her mostly unresponsive form. Turning to him drunkenly, Pumpkin Cake said, “I don’t… don’t know what’s happening to me! I’m tingling all over and I can’t stop! I couldn’t… stop squeezing on your penis. P-Pound help!”

He grabbed her in a hug, saying, “C-calm down! You’ll be okay. I didn’t mean to… s-sorry I…”

“Thank youuu,” Pumpkin said in deliriously happy half comprehension, her tingles and jerking washing away and relaxing in his embrace.

They decided not to do it any more since they didn’t want to be parents, but days later, Pumpkin was feeling so strange. She couldn’t stop thinking about it, about how it had felt, and about how much she had wanted to get Pound to put his boy goo inside her. Faintly she realized she still wanted it, her loins awakening at the thought, and needing to be filled.

So Pound got an erection from Pumpkin sort of… sneakily flashing her fillyhood at him, and she nosed him aside, leading him into the empty back room. Then she pushed him down, and climbed on him, straddling him so she could push her fillyhood against his penis. It was all weird and drooly and she needed to fill it, to make Pound put a baby in her, so she didn’t even ask. Pumpkin just said hastily, “Get… get in I need it… unhh…” fumbling with his penis until she could get it pushed into her entrance.

She felt him slide inside her. He was inside her! Pumpkin Cake didn’t even need to look down, she just sank onto his penis as hard as she could, stretching herself achingly open in there, until she couldn’t push him any deeper. She tried, she tried to push their hips together, and it turned into a thrusting, pushing him in again and again.

Pound Cake pushed her down then, his hips moving powerfully to shove in and out, in and out, so slidy and achingly wonderful. She laid her forelegs against his chest, her hind legs spread to either side as he beared down on her, pushing into her, and sliding against her. It started happening again, that weird squeezy tingly thing that made her want it so bad! It just rushed up in her, and she couldn’t stop clamping around his penis, making her whole body jerk spasmodically. He held her as she couldn’t stop freaking twitching, and squeaking and it felt so good.

Then he started thrusting again, in and out, sliding against and within her, his hips powering to stroke himself to climax inside her vagina. Pumpkin held him back, panting harshly as Pound Cake wasted no time humping his sister. She felt him flare, then thrust erratically, then flare again, pushing deep. Pumpkin gazed up at him, as her brother looked down with a conflicted expression.

“Sorry, sis I’m… gonna hahh.. hahh…” Pound whispered, then Pumpkin arched up as she felt semen pump into her from his penis deep inside. “Take my… baby…” he panted harshly, as Pumpkin moaned in indulgent relief, saying,

“It’s going into me… taking it… every… drop.” She clamped her hind legs on either side of him, letting that fat penis jutting out from Pound Cake’s groin pulse and spurt up into her. “Want it…” Pumpkin growled, pushing against her own belly as if to encourage him to spurt more into it, “Want it… ohhh…”

They panted in the silent stillness, one hunched over and embedded into the other. “We’re gonna get in… trouble,” Pound murmured, “Our parents could check on us any minute.”

“Just…” she said unsurely, as Pound Cake pulled messily out of her. Pumpkin closed her legs, feeling his seed slimily squishing inside her. “I-I’m gonna have your foal,” she told her brother unsurely, but confidently.

“Our parents are gonna kill us!” Pound Cake protested.

“We won’t tell them!” Pumpkin retorted, sitting up on her haunches, “We can just go to that… that meadow we found. I’ll go there and… and give birth there, if you want to… s-see me do it. And then we’ll just d-drop the foal off at the orphanage, because I really really wanna make one inside me. Just once.”

“Okay,” he replied quietly, “Now let’s get out of here before somepony notices we’re gone.”

“Okay, and… and you can… put it in me every day now,” Pumpkin attested, “After we brush our teeth, you can… we’ll make sure that I don’t start… needing it in the middle of the day.”

Not that evening, but the next, Pumpkin was neatly mounted by Pound Cake, and she stood there, panting in the darkness, as he snuck into her room, and into her vagina. She was sweating from the… the squeezy thing he kept making her do. Then he started jerking inside her, and she said gladly, “There you go. Ohh yes. Hnnnmh…” at the pulses of seed that filled her, and changed her.

About eleven months later, Pumpkin Cake was piking her legs lying on her side, tensing up as her gigantic whole belly womb clench-clenched, a flare of aching tension every time it flexed so powerfully.

“I wonder why it squeezes twice like that?” Pound Cake wondered of the sweating, panting, birthing Pumpkin Cake.

“I don’t hhnhhnnh“ Pumpkin said through clenched teeth around the rippling power pushing a foal out of her vagina. “One to hnhhhnnh stretch my hnhhhnnh can’t talk hnhhhnnh“

“You’re really trying to push the nose out,” Pound described for her, “It just keeps going back in. Just in and out.”

“Yesshh…” Pumpkin slurred, trying to push the nose out, feeling it slip back in, out, in, if she could only push out enough to get the head… but she couldn’t. “There’s a… a pony coming out of me! Pumpkin declared to Pound Cake tearfully, as her contractions gave up for the moment. “My vagina needs to push my foal out of me! Please hug me, please I need to… to hug you so I can push really hard. My belly is so big and it needs to… it won’t stop anymore! I can’t stop doing it hurry, please”

So Pound Cake lay with her and hugged her, and Pumpkin gripped him tightly, birthing as hard as she could. “It just… hnhhhnnh takes me over hnhhhnnh”she panted harshly, trying to describe the contractions, “I’m squeezing so hnhhhnnh so hard.”

She rolled on top of Pound Cake then, pressing him down with her belly, her giant belly that was flexing like a monster. No, she was the monster, trying to use him to push her belly more, trying to get it to flex harder. Pound Cake just murmured, “It’s so powerful…” his forelegs pressing against the sides of her belly as Pumpkin Cake flexed it powerfully again and again. Nose goes out, nose goes in, out, in. Out… in.

Pumpkin Cake figured she was going to be doing this for all eternity, with a foal’s nose and forelegs sticking out of her vagina. She could even stand up and sort of walk around, and Pound Cake said it just looked really cool. But then Pumpkin was standing there panting again, her belly flexing to put incredible pressure on that nose stretching her open so wide. Then she’d crash down on her side sometimes, and just tense up as her body worked her over, unable to think about anything other than the powerful clenching that took her over.

She wasn’t even able to walk at one point really. The slightest clench and she’d need to lay down, or lay with Pound preferably, but Pumpkin stopped caring even about that. She only cared about her next contraction, just laying there hating her vagina for being so sensitive and tight, and trying to punish it as much as possible with her thickly flexing womb. So Pound was just making himself occupied looking between her legs when it happened. Pumpkin’s flexing was so powerful, and so determined, and she faintly heard him shout, “It’s coming out more! Push harder!”

“How am I supposed to push harder?!” Pumpkin Cake wanted to yell at him, because she was just trying to deal with her belly pushing a foal out of her, all on its own. The contractions didn’t seem stronger, but then she felt something slip, as her vagina blessedly closed down, and Pound Cake declared “The head’s out!”

“Oh that’s…” Pumpkin said in relief that quickly faded as the urgency rose in her, “O-o-oh Pound I’m—” and another set of contractions came right after that one. She couldn’t stop squeezing, even stronger, and more irregular, hardly even a rhythm, just Pumpkin Cake squeezing as much as she could. She felt stuff slipping through her, stretching her open and that making her contract even more, pushing it further along.

“I don’t wanna give—birth! I can’t… stop!” Pumpkin Cake cried, irrationally wishing to bring the foal back in, to be pregnant forever. She flexed and it slid out. She flexed and it slid out. No! Pumpkin saw Pound Cake cradling a slimy, icky, plastered down fur, and very confused looking foal, whose hips were just stuck inside Pumpkin’s groin. Pumpkin moaned in tortured indulgence as her womb achingly contracted and the rest of the foal just dumped out of her. Her belly just freaking collapsed, and the hind legs were still… in her a little.

“You can… you can pull the legs out I think,” Pumpkin said uncertainly, trying to catch her breath. Was that it? How long had they been doing this? She wasn’t even thinking about time, other than how soon her next contraction was going to be. Pound Cake pulled the little legs out of her vagina and Pumpkin watched in awe as he lifted the foal free of her entirely. “That came out of me?!” Pumpkin protested faintly, unable to believe how incredible that was, “That’s… amazing!”

“Are your instincts to be a mother kicking in?” her brother asked.

“I think so!” she said hopefully, “Let me hold her, I wanna start loving her and and really loving her and stuff.”

She was having trouble sitting up, but Pound Cake nestled the foal in Pumpkin’s forelegs, and the foal looked up at her with those little beady eyes, and Pumpkin said, “Oh, I… you were in my belly! She’s so… so tiny! Oh wow… I… I love her…” Pumpkin started crying, as she said, “Our… our mom felt like this! She… she loves us so much. Oh I never never felt like… she’s the most amazing thing in the whole world.”

“I think you both are,” Pound Cake said in admiration, as Pumpkin started licking the slimy stuff off her foal, just like a mother.

The foal protested with a quiet squeal as Pumpkin pulled her against her chest, giggling, “I’m a mommy, see? She’s my baby and you’re the daddy!”

“Does she want milk?” Pound asked thoughtfully.

“Oh, oh I bet she does!” Pumpkin declared, struggling… almost struggling up. She didn’t have to though, thankfully, because when Pound led the foal to her flank, the little filly nosed around for just a second before latching on and sucking hard.

“Woah, she really…” Pumpkin startled, then said in a small voice, “I–I’m feeding her. I’m not doing anything, and it’s just coming out of me. S-s-so amazing.”
