We're barely in the tent before I'm wanting to fuck him, to end this colt's destiny of chastity, and finally feel what it's like for a horny boy to cum inside me. It's been a whole week, and I'm not waiting one day longer! "This's sooo cool," I say eagerly, turning to him with a huge grin as he steps into the tent, "Nopony can see us here. We could do anything we want together, and nopony would know." "Like what?" the grey pegasus asks curiously. My tail bobs behind me. "Liiike... have you ever looked under a filly's tail?" I ask him innocently. "What? No, that's where you're not supposed to touch!" he says, offended. "I bet I know why," I say, turning and flagging my deep pink tail for him. "Because touching my fillyhood makes me wanna do stuff." "Do... what?" he asks, sounding distracted. I wonder why. "Like," I postulate, shifting my hips back and forth, "Getting you to touch it more. And getting hungry down there." "Hungry?" he squeaks. I look back and he's clearly staring at my rear end. "Don't worry, I can't eat anything with it. It's just like hunger but I wanna do something different than eating." "Different like what?" he asks. "Well... you wanna feel what it's like?" I tell him, turning to face him. "To get hungry but not for food. It's something grownups don't want us to know, but it's the most wonderful thing in the world!" "To get hungry?" he asks, confused. "To get fed!" I retort. "I'm gonna make you hungry, and then I'm gonna feed you, not with food, but with rubbing. The only thing is we have to be able to touch under each other's tails." "W-well you showed me, so I don't mind," he says nervously. "I..." blushing, I admit, "I wanna see under your tail too. A-and touch you there, too. I'm not supposed to touch you, 'cause if I do, then I can get you to do something to me." "What's that?" he asks faintly. "It's a surprise," I tell him sweetly, "But I really wanna feel it. So turn around and let me touch you back there. I... I really like under your tail, because I'm a filly, so it's okay to show me." "Why because you're a filly?" he asks skeptically. "Do you see any balls?" I reply, turning away and lifting my tail again. "Any sort of boy thing down there? No, I only have a plain old round belly, with a little thingy under my butthole." Turning back, I admit, "So the only way for me to ever play with a boy's stuff is if he lets me. So... please?" I don't even have to put forth the puppy eyes. "Ugh, fine," he says, turning and lifting his tail, "B-but this better not be a joke." "It is the opposite of a joke," I say in awe. He smells so good down there, even at his age. Musky and sweaty and spicy. I want him to put that wonderful scent inside me. His cute little balls hang in their grey furred ballsack, concealing a little sheath on the other side of them. "Okay, so tell me if this feels good," I tell him, raising a forearm to lift his balls up, resting on it. "That feels... okay, I guess?" he says uncertainly, "What's the point of his?" "Well um..." I say, brushing my right hoof against the sheath I can feel as a slight dangling edge there. He stiffens at that, good. "I'm kinda gonna touch your penis," I say, pressing the frog of my hoof against his sheath, and slightly rotating it around. "My penis?" he says tensely, "But it's not even out!" "Try to keep it inside," I tell him gleefully, "All I'm gonna do is touch your sheath, so just don't take your penis out." "O-okay," he says uncertainly, and true to his word, he lasts almost another minute, before his sheath bulges obscenely against my hoof during that soft stroking. "I... I can't--!" he says anxiously, as his penis slides out to drape on my forearm. "Oh, look at this!" I say coyly, releasing his dong to dangle, while I walk to the side of him, sitting on my belly to gaze under his legs at that penis.. "Thought you were gonna keep your penis from coming out." "It just started... it was feeling good," he explains desperately, "It just came out on its own. I couldn't stop it! I'll try to..." I touch his penis, squeezing it between my two forehooves, rotating them in small, gentle circles. He surges underneath my hooves, moaning above me, as his penis thickens. "Feel good yet?" I ask. "I-it's," he says, lifting a leg and looking with me at his dick, "It's getting really big, and it keeps swelling!" "Well I know what'll make it feel really good, I say, lowering my head under his raised hind leg. He looks at me in paralysis as I leisurely open my mouth, and just gently nom the flat tip of his penis. "Y-you're..." he says, "What are you doing?" I don't answer. Instead, I slide my lips down his shaft, extending my tongue to press against it. "Oh that's..." he says faintly, "Holy cow..." I get the entire head into my mouth, and his hips surge, instinctively thrusting that penis into my mouth. It's salty, and my nose is still heavy with his musk, making my eyes lose focus, and my nethers feel like they're melting, preparing me to be his broodmare. "Good!" he yelps, "That feels good!" and he stiffens and thickens, until his flesh is straining and tense. It's still not huge or anything, but I want it bad. "You want it huh?" I tell him, taking my mouth from the twitching shaft. "Y-yeah, I really like it when you lick me there," he says, blushing. "I don't know why it's... big. So you can... lick it?" "Oh, I'll show you why it's big," I assure him, "But first I want to show you what it feels to be hungry in my fillyhood." I draw my tongue along his shaft, wrapping it around underneath, as if my tongue where a wet, slippery tentacle, which it technically is, I suppose. He moans again and humps into the air. Already his body's developed the instinct to fuck. This is going inside me. Pulling back, I ask, "You want me to lick you more?" "Yes!" he says tensely, "Please!" I massage his penis with my mouth, sliding my tongue inside, and sticking my head between his forelegs to swallow the tip, letting his instinctive thrusts fuck my cheek. I know he's gonna lunge forward, so I pull away quick, and he starts walking forward, trying to get his penis in my mouth again as I dance away from him, saying "Is your penis feeling hungry? Are you feeling hungry for me to lick more?" "It feels so achy and hungry for your..." he pants heavily hunched over his colthood like it was a heavy weight. "I want to put my penis in your mouth again!" "No, you want to put your penis in my vagina," I contest smugly, raising my tail at him. "You thought my mouth felt good," I say, drunk with desire, "But my vagina is even hotter and slimier. Your penis wants it." Curling my tail to brush my own vulva with its tip, I say, "Down... here. I have a vagina. It... it has a special smell, for you. Go ahead... it doesn't smell bad, I promise." He walks stiffly up, and I don't know if he hesitates under there, but I do hear his unmitigated wonder, in saying, "Wow..." "Go ahead, smell it good," I purr, curling my magenta tail over his dark blue maned head, "It makes you want to put your penis in more. You wanna try licking it... a little bit?" Then my pupils narrow as a hot, wet tongue slides against me down there, spreading my folds just briefly. "I-Is this okay?" he asks as I remain frozen in shock at how intense that felt. "You don't smell bad down here," he says, "You smell really good!" "Smell it..." I say trying to relax, "As much as you can. You wanna smell my... special scent down there, and lick me and..." He starts licking again. It feels so strange, because I don't orgasm right away. The tingling just builds up into this pleasant rising wave. I-I think I'm squeezing on the inside, but I can't tell! "Keep licking," I moan, just melting in there, and just... rocking back against him. I wanna get fucked! I... I can't stop orgasming! His licking won't stop like my hoof can. I can't control it! "Oh please, don't stop, just a little more~" I moan, shivering as I need it more, the more he explores me. Winking finally pushes me over, the explosions of pleasure as my clitoris pushes out, fighting with his tongue. He's just licking me, not even pushing it deep. I c-c-an't stop it's filling me up. Every muscle in my body is tensing. A cold fire of pleasure engulfing me until I can't stand it, then flaring even higher than that. A squeal escapes me as everything starts... flexing down there. "Are you okay?" he asks, as I whimper, unable to deal with feeling this good. I can't stop orgasming! He's not even licking me. It feels so good! In my shallow breathing, I try to squeak, "Okay! I'm... okay!" but then I just have to ride it, rocking mindlessly at the waves of pleasure. Vaguely I realize my vagina isn't even doing anything anymore, but rush after rush of pleasure flows from it, making it hard to breathe it's so intense. "It's..." I say, finally able to think enough to form sentences. It's fading away so deliciously slowly! "That's the best feeling..." I tell him. "Your... tongue made be feel that." "I... you want me to keep licking?" he asks, "Your fillyhood started... moving weird." "Your penis would feel better," I say breathlessly, "Like when your daddy put his penis in your mommy." "H-he did, I guess..." Rumble admits, "I really wanna." "If you climb up on my butt, you should be able to get it in. Don't worry, I can totally hold your weight," I assure him, stepping back to curl my tail over Rumble's head again. "S-see my fillyhood?" I tell him ardently, "Your mommy has a fillyhood just like I do. Imagine mine stretching wide open, as a foal's head squeezes right out of it!" "J-just... like," his hoof touches me, aah! "Stretching open my... pocket..." I pant, resisting the urge to mash my cunt into his snout, "Your mommy had a big foal in her belly. Her belly started squeezing one day. It squeezed harder and harder, until it was all she could do. And every time it squeezed, it pushed your head against her vagina from the inside, right here, more and more, until you stretched her open and slid right out." He starts licking me again, and a horsey moan escapes me. He thinks this's gonna make me stop talking? "Your daddy... put his penis in your mommy... just like you're gonna do to me," I huff. "You're gonna push your penis deep inside, and you're gonna change me. Your mommy was... just a filly, not a mommy. Then your daddy put his penis in, and filled her with his semen. It changed... her. Gonna change... me. My belly's gonna get bigger and bigger... growing your foal inside me. Gonna push your foal... outta my vagina! Gonna lick them and nurse and be their mommy~!" Oh fuck, I'm about to orgasm again! I need him inside me first! I canter forward, away from that beautiful tongue, quivering with need to be bred. Waving my tail at him, unable to stop winking, I coo, "You wanna do that to me, Rumble~? Just push your penis in where your tongue was, where I'm hot, and wet? You wanna make me start turning into a mommy?" "I... I don't know..." he says, staring at my shifting cunt. "Just push your penis in, and you'll make me start growing a foal in there," I tell him encouragingly, "Just climb on my rump, and you can. Your penis wants to be inside me. You'll feel so good if you do." "I... I want..." he says, stepping forward. I slide my slimy rump up against his chest, trying to back under him, to get that penis inside me. He doesn't stop me. He hooks his forelegs over my hips as I push back. "I'm gonna feel so good with your penis inside me," I moan urgently. "You are?" he asks, slapping my belly with that shaft. Slapping my teats! "My vagina feels really good... with a penis inside it," I say, fidgeting my rump around. "If you put it in, I'll tell you how good it feels... right where your tongue was, just the tip pressed against me. That's right, you hunt around for---" Holy crap his penis is huge! "I felt... that..." I say tensely as something inside me gets stretched wide, straining as a colt's penis slides into it. "That's... my entrance. You can go deeEEP!" I squeal as his hips surge and that delicious tense stretch opens me up deeper and deeper inside. His hips collide with mine, and I'm just... standing there splay-legged, full of his penis. Oh holy fuck, I'm gonna have his foal. I'm a female, so female right now, and this colt's gonna make me give birth! "You're hot in there!" he shouts in shock. "You're hard in there," I report back lustfully. "I am hard," he groans, hugging my rear, "and tingly." "My vagina feels so stretched," I tell him, "I feel so good. R-right now, you feel really good, right?" "Yuh," he says almost tenderly if we weren't so excited. "My vagina feels just as good as your penis," I tell him, "I feel the same tingles, that make you want it. You want your penis inside me, and you wanna give me your foal, and your penis's... making me feel like that too. I can't stop. You don't wanna leave..." "I... I wanna be in you," he admits, grinding against me achingly deep, "Am I p-putting a foal inside you?" "Not yet," I tell him hungrily, "Pull out first. If you pull out a little, then push in again, and keep doing that, you'll ejaculate." "Ejaculate?" he asks, pulling out and pushing in again and oh the sliding just makes my tingling vagina explode with need! "It'll... jerk... inside me when you... ejaculate," I say tensely, "You'll have to push it deep... and squirt semen as deep into me as you can." "H-how do I do that," he says, humping uncertainly. "Fucking is how," I tell him, "In and out, in and out, faster and faster. Focus on the tingling, and how wet and hot I feel. Where your penis is right now. Think about... Pinchy the mommy. You're gonna do that to me. You're gonna have a... a foal you can hug. I'm gonna make it for you, if you just pull in and out, in and out~" My vagina explodes in pleasure, as Rumble hugs me close, and starts humping for all he's worth. I just... orgasm! I can't stop! He humps and humps until I.. clench so... hard that he has to struggle to jam it into me. He stops humping then, holding deep as he says, "A-are you making a foal? You're squeezing really hard." "So... good..." is all I can say, shuddering against him as my cunt milks his penis, my whole body shimmering with mind blowing pleasure. Orgasm is so much better when you have a penis in you, ready to impregnate you. "Do I keep pushing?" he asks frantically, "I-I want to!" I can't answer though, all I can do is be this wonderful, slutty, horny, cumming filly. As my pussy settles down, I say to him in the tingling haze of orgasm, "You haven't... given me a baby yet. Keep pushing, in and out, if you wanna give me a baby. If you want your penis to... to ejaculate in me." Rumble starts fucking again, hesitantly at first, but his hips pick up to a steady, instinctive rhythm that makes me stand there and just take it, huffing and rocking back and forth. My tail hugs around behind his thrusting rear as sweat trickles down our sides. I... I think I'm gonna orgasm again! He's fucking me! I'm a filly! I'm being raped! This is amazing!" Then Rumble shoves deep and flares. I can feel it! Expanding inside me, making a joyful squeal sneak out of my throat. "You pushed deep!" I tell him, "You're gonna ejaculate!" He starts fucking again as he deflates, saying, "I... I felt... couldn't slide it, had to... deep." "Feel it fill you!" I beg, "Your whole body on... fire, until you can't stand it! You're inside me!" Rumble fucks me so earnestly, saying, "I... I think it's... it's filling me up! Nh... nh...nh!" He pushes deep and holds it, flaring again. I feel so full. "Now you're gonna squirt out your seed," I coo to him, "Ready to turn me into a mommy?" To my delight, fascination, and arousal, I feel something just splurt against me in there, right from the tip of his penis. One, two, three. I don't know if I'm orgasming, or still orgasming, still just singing with pleasure for this spurting penis in my vagina. "That's it, put it all deep inside," I reassure the orgasming colt, with a gentle hug of my tail around behind Rumble while he's ejaculating inside me. Four, five, six. "I feel your semen~" I croon. It's not even squirting against me anymore, just spreading within me warmly. I can't believe he makes eight squirts. That's more than I ever ejaculated as a human. And he's just a kid! What's gonna happen when he gets to be a stallion? Oh yesss I'm full of a colt's seed right now. And his penis! He's panting and relaxing against me, and this is the best thing I've ever felt ever. "That was..." he says in disbelief and wonder, "I could feel it squirting out! I wanted to do it so bad!" "I wanted it too," I agree heartily, "Felt your seed just... splurt into me. It's gonna stay inside me, changing me into a mommy~" "I... b-but you're just a filly!" he protests, "I just... did that to you! You're gonna have a foal now?" "Yep," I tell him with a warm satisfaction in my belly, "In eleven months I'm gonna be pushing a foal out, where your penis is." "I couldn't stop thinking about that little... opening stretching wide," he says in disbelief. "You can really fit a foal out of there?" "I sure as heck better be able to!" I tell him assertively, my lust still riding high from the presence of that colt's penis. I start trying to fuck him more, by rocking against him. I just can't stop wanting it! "H-hey that sort of doesn't..." he says disaffectedly, but I don't care. And to my delight, the confused colt grips my hips and starts fucking me again. His heart isn't in it though, and I know how males feel after orgasm, so I shudder to a stop, saying, "Thank you~. Don't worry, you'll get more semen pretty soon, and you can do this again." A squeeze around his sensitive shaft unavoidable, I grunt with the effort of doing it, but then I say, "Now your penis's gonna get soft, and small, and go back into the sheath." "S-should I keep um... fucking you?" he asks. "No, just hug my butt, and... let me keep it nice and warm~" I tell him, wriggling my ass back against his hips. "Your penis feels so cute and soft right now." He is clearly losing turgidity, and sliding too, sliding out of me. I don't want him to go though. I want a dozen stallions to keep filling me and filling me. But feeling a colt's penis soften and shrink inside me is its own brand of adorable, and I relish every moment, until I say, "Oh it looks like... I can't keep you inside anymore. You're gonna slip right---!" He slips out of me. "---out," I conclude. "Your penis's all outta me, but the seed you squirted is still in there, changing me into a mommy. Standing before him coyly, with that secret happening in my hips, I ask him, "How's it feel to do that to a filly, huh daddy?" "I... I'm a daddy then, I guess?" he says. "I'm the one who has to change," I tell him solemnly. "My organs have to move out of the way, and my body has to grow into my womb and start feeding it. So I'm gonna start getting hungrier, for weirder stuff. It's also gonna change me to start loving the foal. I'm gonna start feeling more loving, and protective, and not caring about anything but my baby." "That doesn't sound... all that great," he says with a wince. "Well, that's why I need friends, to remind me that my baby's not the only thing worth caring about," I tell him. "And to take my baby away from me, so I don't have to feel so protective, so much that it's not good for me." "Your friends take away your baby?" he asks skeptically. "If they're good friends, yeah!" I assert. "They'll do it even if I get upset, and they can hold the foal, and give the foal rides, and play with them. And when they give it back I'll be totally glad they did, since it was just my mommy instincts making me stupid. Don't worry, I'm gonna turn into a mommy, and I already wanna give birth, but I won't let it turn me into a mommy like my mommy." Hesitating, I add, "E-even if I have to let my foal die because she's not getting better, and I can't afford the hospital bills." He doesn't know what to say to that, that's clear enough. "I'm glad that my... mommy kept me alive," I tell him, "And she loved me so much that she even tried giving me a new soul. B-but it was still stupid of her. She's had to be super sad for too long, and I dunno how much she can get better. A-and all that money could've been going to... other things, instead of wasting time on a filly who won't wake up." "Still, she was your mommy," he says insistently. "She had to save you!" "And that's the problem with being a mommy," I reply unrepentently, "Imagine if she didn't have to save me. When she found out I wouldn't wake up, she could have got me a new soul right away. But instead her stupid mommy instincts made her try and try. If she knew that she was just being a stupid mommy, then maybe she could've stopped being a mommy, just for a little bit, and started being a pony again." "Oh, that makes sense," he says, looking unsure of his conviction there. "And you wouldn't... do stupid things?" "Oh I'll do plenty of stupid things," I say rolling my eyes, "But at least I'll know it's my ovaries making me do it." "...ovaries?" "You know, your balls?" I prompt, pointing between his hind legs. "You used those to squirt a teeny bit of sperm into your semen, before ejaculating it into me." Before he can say, "I did?" I add, "Most colts can't feel it. Sometimes it gets a little sore after, if it really squirted a lot, but usually it's just part of the penis jerking. But what I meant is your balls are where your sperm are, and those are what swim to my egg, and turn it into a zygote." Before he can etc, I add, "And a zygote is an egg, after a sperm pushed into it. My egg's just an egg right now, but your sperm are gonna turn it into something that knows how to grow, and how to stick to my womb and let me start feeding it in there. That's a zygote. It's like a... tiny little machine, and when you run the machine, instead of blowing air, or grinding flour, it starts turning itself into a foal. So... you got made from a zygote, that was turned on by attaching to your mommy's womb, and built you bit by bit, until you had a nose, and hooves, and eyeballs, and... wings and stuff." "That's... really weird," he says uncertainly. "Just think of it like a little thing that grows into a foal," I tell him, "It isn't any different from my egg at first, and by the end it's um... you. Then you get born." Blushing, I add, "W-well not you, I mean. My foal's gonna be a pony like you though, once my egg gets zygoted, and one day he's gonna be wondering what the heck a zygote is too." "I hope he has a braniac filly to tell him," Rumble says, with a blushing smile. Smiling back, I say gratefully, "I never thought I'd... be able to do that. Just... grow a pony in my belly. But now that I'm um... awake, and in heat, I totally can, so I really wanna try it." "Hey if you wanna try it, I'll be happy to put a foal in you any time you want," Rumble says with a grin, "That felt awesome!" "You know the best thing?" I tell him with a grin myself, "It might not work the first time. You might need to do it five or six times, before it happens to me for sure." "O-oh," he says, looking with worry at his groin. "Don't worry, you're gonna want it just as much the next time," I tell him, "Once your body gets more semen ready to go, you'll wanna get it in me as soon as you can. And the best best thing is..." I pause, then tell the interested colt, "I don't need any semen after I already have a foal in me, right? The best thing is even when I've already got a big belly with a foal in it, you can still stick your penis in me, and ejaculate in me any time you want, for the next eleven months!" "Oh, that sounds great!" he says appreciatively. "Yeah, I can't wait until my belly's all big," I tell him eagerly, "You can push against it and feel how round it is, and know your foal's there growing inside me, even while you're in me, ejaculating more." He seems speechless at that. Hopefully a good thing. "Though I suppose you might have trouble putting your penis inside my vagina at the very end," I speculate, "When I'm giving birth, and it's all stretched out around my foal and stuff."
