“Whatcha got there, Purple?” “Mff!” Purple dropped the book in front of her, the front cover reading “Sex 101.” “It’s a game called sex, and my older brother said it was really fun,” Purple said, “This book has instructions and everything!” “Did you read it?” Blue asked, looking at the intimidating looking tome. “No, I just borrowed it from him,” Purple said with a rakish toss of his blue scruffy mane, adding a little slyly, “He doesn’t know I borrowed it though. I just heard my brother talking about it with his special somepony.” “Ooh, sneaky,” Blue said, peering down at it with eager, wide eyes, “I wonder what kinda game it is?” “A grownup game, that’s for sure!” Purple said eagerly, “So let’s look in it!” They turned open the book, reading through it idly, before Blue whined, “It’s all just boring stuff to get ready before you play the game. Where’s the actual instructions?” “I dunno, it says to make sure to do it privately,” Purple pointed out, “So maybe these are important.” Blue appeared to be listening, but then started nosing pages forward rapidly, until she declared, “Aha! There’s a picture!” “Huh, why’s that pony hugging that other pony’s butt?” Purple asked curiously, “It’s a game like leapfrog?” “It says here that the male mounts the female,” Blue said, looking at the text and indicators, “So that’s the female pony, and that’s the male pony, and that’s his... penis?” “It can’t be, it’s sticking right into her!” Purple protested. “Hold on,” Blue said, flipping a few pages back to the beginning of the section. “Okay, here’s an outline!” 1. anatomy 1. male 1. penis 2. testicles 3. semen 2. female 1. labia 2. vagina 3. ovaries 2. foreplay 1. arousal 2. hoofing 3. oral stimulation 4. lubrication 5. erection 3. coitus 1. mounting 2. penetration 3. thrusting 4. the flare 5. climax 6. ejaculation 4. intromission 1. refractory period 2. cuddling 3. pair bonding “Okay, what’s foreplay?” Purple asked, “That sounds like where you actually play.” “Well, it says... huh,” Blue replied, looking with puzzlement at the text. “You... touch the labia with your hoof?” he asked, puzzled. “What are labia?” Rolling her eyes, Blue said, “Don’t you know anything? It’s just another word for my pee place.” “How am I supposed to know that?” he asked, in a hurt tone. “Well I know what a penis is!” she declared, “That’s your pee place!” “Yeah, but it already says pee in it,” Purple protested, “What does labia have to do with pee?” “I dunno, but it says... the stallion should to press the frog of his hoof against the mare’s labia, and gently part them, to massage inside.” “That... sounds weird,” he says, “What if it makes you pee?” “...we should both probably pee first,” she said, jumping to her hooves, “And be sure to wash your pee place really good!” After Blue and Purple flushed, washed, and headed out of the bathroom, Purple walked up to her, as Blue said, “C’mon, let’s go in your room. They said it should be private, so let’s just close the door.” “Good idea,” he said warily, “We’ll probably get in trouble if my parents come home and catch me with my brother’s book.” In the colt’s surprisingly tidy room, with all the toys cleaned off the floor and in the toy chest by his bed, the two foals once again pored over “Sex 101.” “Yeah, it definitely says labia are the pee place,” she says, “And I touched them with my hoof, and they’re totally clean, so it’s totally okay if you totally touch them with—” “Calm down, I’m not chickening out,” he interrupted, “This is a grownup game, so of course it’s got some weird rules. If it made sense we woulda figured it out already on our own.” “Yeah, so um...” Blue turned, and raised her purple tail, exposing her fuzzy blue butt to him, “Try pressing it, like they say in the book.” Purple looked with interest at the slid between her thighs, walking up and saying, “Okay, but just to see if we’re doing the foreplay part right.” He pushed his hoof against her, and was surprised by how soft she felt. She was surprised about how soft she felt, and tickly! “That tickles!” she protested, and Purple pulled his hoof away, saying, “Really?” “No, it... it did tickle, but not too much,” she said, “Just kinda weird having somepony else touching there.” “Oh, well I’ll be careful,” he said reassuringly. “Okay, once we get this step down, we can go to the next one,” she agreed, presenting for him again. “Hehe... I feel a little tickly just raising my tail to you,” she added. “Yeah,” he giggled indulgently, “You’re not supposed to do that, but I won’t tell anypony.” Once again, he palpated her fuzzy labia, and she quieted at that, both of them concentrating on the sensation, until he said, “Hey! I thought you said you peed!” “I did!” she replied, turning to look back at him incredulously. “Then why’s my hoof getting wet?” he asked, holding it up accusingly. “That... doesn’t smell like pee,” she said insecurely, “I wouldn’t *pee* on you.” “You *smelled* it?” he asked, looking at his hoof in horror. “Try smelling it!” she insisted, “It’s not pee it’s like some spicy... it just smells like me.” He did and his eyes widened, “Woah, it does smell like you. And not pee at all.” “W-well I’ll try not to... do that any more,” she replied, presenting to him again, “But c’mon, do it a little more. That was starting to feel good.” He did, and her breathing was deepening, her hind legs growing stiff, when he exclaimed, “It’s doing it again!” “What?” she squeaked. “Your pee place keeps making this... slimy stuff!” he declared. “I can’t help it!” she protested, “Maybe this is part of the game? I dunno what my pee place is doing. It just got... squirmy slimy or something.” They consulted the rules, looking around them for a while, until Blue declared, “Lubrication! That’s it. See?” “The female’s vagina will produce a slimy lubrication, when aroused,” he recited, “To aid the penetration and stimulate the male to ejaculate.” “Oh, there’s a section on ejaculating too,” she said, turning to that page. “Ejaculation,” he read, “Occurs in the male during orgasm. Um... his prostate gland dischar...ges a thick fluid, which mixes with the semehn from his seminal vesicals. Powerful muscul... muscle contractions propel the semehn up the length of his penis, then eject it forcefully into the female’s uhterus.” “Uhterus doesn’t sound right...” she said in a dissatisfied tone. “I dunno, it sounds kind of like peeing,” he said unhappily. “You don’t pee a thick fluid, do you?” she asked skeptically, “It’s probably just like my... other fluid. The slimy stuff.” “Guess so,” he replied, “So um... back to foreplay?” “I wanna try the other stuff now,” she said eagerly. A few more moments looking at it, and Purple exclaimed, “I have to *lick* it?!” “That can’t be right,” Blue added in frustration, “But it says right here, the male’s tongue can penetrate the female’s labia, and stimulate her arousal, in prepration for soitus.” “I’m *not* gonna lick your pee place,” Purple said, folding his forelegs stubbornly. “Wasn’t asking you to,” she said, “Don’t worry. Let’s just move on to the next thing... oh that’s lubrication. Okay the next thing is erection.” They both read it, and he said, “Huh, so that’s why it was doing that.” “Your penis did that before?” she asked, looking at him in surprise. “Well, yeah but not from rubbing. Just sometimes it’s... stiff like when I wake up in the morning,” he said, “It goes back in on its own.” “It says the penis stiffens and thickens,” she said, looking at the text thoughtfully, “So your pee place just... swells up or something?” “Swells up?” he asked in confusion. “Never mind,” she said, blushing. “Well, I touched your pee place,” he said, “So now I guess you get to touch mine.” “Hey, I won’t chicken out, either!” she said, sticking her tongue out at him. Purple laid back against the bed, and Blue cautiously stroked her frog on his sheath. She quickly got distracted by his purple fuzzy balls, lifting them on her foreleg, saying, “Woah, these are really soft!” “Careful,” he said tensely, “It hurts a *lot* when you even tap those things.” “Oh I’m hurting you?” she asked with worry, dropping his balls. “No, just touch them softly,” he said, lifting them with his own forehoof, “Just don’t whack ‘em and I’ll be fine.” “Okay,” Blue said pensively, curling forward to attend to his groin again. Her soft stroking of his sheathe and balls quickly had its intended effect, as Blue squeaked in surprise, “What are you doing?! Your... thing exploded!” “What?” he asked kind of already dazed with pleasure, “You mean how my penis came out?” “Your... penis comes out?” Blue asked uncertainly, looking at the chubby dark cylinder. “Yeah, what did you think it did?” he asked. “I just thought it... you know, just opened, like mine. Mine doesn’t just... explode like that!” “Huh, well mine does this every time I pee,” he said, “Hold on I’ll make sure it’s out all the way. You thought my penis was just my sheath?” “I... no,” she said, blushing and scrunching, “I did not. B-but I didn’t know you had a special... thing that comes out.” “Alright, see it’s simple,” he said, “It’s like whenever I pee. Um...” adjusting himself slightly, he slid out of his sheath fully, saying, “There, this is my penis. You’ve never seen a penis before?” “When would I have been able to do that?” she asked, “A colt never did that in front of me before!” “Oh, it’s because I only do it when I’m going to the bathroom,” he declared in surprise, “And right when I wake up sometimes. So you wouldn’t be around any colts then. They make us go to the bathroom in a whole different room than the fillies!” “Just to keep me from seeing your penis?” she asked, looking at it again, “That’s messed up. I don’t mind if you have a... penis. It doesn’t even look like you have a hole down there anymore, not like mine.” “So you don’t have a penis that comes out,” he prompted. “No,” she said self-consciously, “Just a... little hole. Can I... touch your penis?” “That’s what the game says to do, right?” he asked, leaning back, “Go ahead and touch it!” Blue did so, and her clumsy minstrations still managed to get it erect. “Wow...” she said, balancing the stiff rod on her hoof, “It’s getting *really* big.” “It’s... like when I wake up sometimes,” Purple said tensely, watching her play with his penis, “Your touching is making it do that for some reason.” She continued on a little longer, until leaning forward, she took a long lick along the side of his penis. “Hoi—!” he squeaked, arching up at her soft, hot, slimy tongue. Then she continued to assault his cock, licking it, and mouthing over it, and shoving her blue furred snout right into his groin. “What are you doing?” he asked, pushing her away. “It said we could lick!” she protested, blushing heavily as she looked up at him, “I just wanted to try it. Your penis smells *really* good.” “A-and tasted good?” he asked uncertainly. “No, I thought it might, but it just tastes um... warm, a little squishy, but still stiff. Mostly I could only feel it,” she said uncertainly. “Well if you want to, go ahead,” he said, leaning back again, “It felt incredible!” “It did?” she asked cluelessly. “Yeah,” he said with a grin, “It felt so good, I just... didn’t know why you wanted to do it!” “Well, okay...” Blue said, looking hungrily at Purple’s groin again. This time, her tongue slid along the fur of his balls. “So soft and smelly...” she murmured, shoving her round nose under them, and squirming her thighs together. “Y-yeah, but my penis feels the best,” he said to her attentions, as she sucked each of his testicles into her mouth, just experimentally. “Oh, right,” Blue said, moving to his penis again, making Purple groan in pleasure, leaning back as his best friend suckled on his penis. “There’s a hole in it,” Blue said quietly then, just cupping it in the crook of her hoof and looking at the tip, “Just like the picture in the book.” “Y-yeah, that’s where my pee comes out,” he said uncertainly. “That’s where the book said your semehn comes out!” Blue replied, “Right here...” He squeaked when she touched the tip with her nose. Then she sucked on the tip, and he felt a strange sort of vertigo, at the pleasant tingle rushing up in him. Blue dropped his penis to slap against his belly then, turning and lifting her tail, practically shoving her rump in his face. “What are you doing?!” he asked, pushing the filly’s butt away. “Can you lick, please?” she whimpered, “Just a little. I feel really tickly down there and... see?” “Woah, woah,” he said, pushing her further away. “You can’t just stick your butt in my face like that.” “I... I dunno, your penis was just making me feel...” she said, trembling there before him, “Like I could just...” Then she turned, and her tail bobbed high in the air, her butt facing his direction as her pink clitoris winked out and back in. “I want you to *see* me down there,” she moaned, “I dunno, I just can’t stop thinking about it. I... I wanna show you how bad I need to be licked.” “Let’s just look at the instructions,” he replied nervously, his erection aching at the sight of that filly’s winking butt. “Yeah, I’m... just being stupid, I dunno what I’m even doing,” she blushed, lowering her tail with effort, and trotting over to the book. He joined her, as Blue read out loud. “Foreplay is intended to increase arousal,” Blue recited, “When a female pony becomes aroused, she will feel an urge to present for a stallion, an instinctive action whereby she displays her receptivity by pointing her rump at him and lifting her tail. Oh.” “It *says* you have to do that?” Purple asked incredulously. “I didn’t even know it was going to say that!” she protested, “I just sort of... wanted to. Really bad. And I still do, sort of!” “I guess you displayed your receptivity,” he replied, looking her way with worry. “You feel an urge to present for um... me?” “Yeah, I... I guess,” Blue said, glancing at the floor. “Well go ahead. If you feel an urge, just do it. Maybe it’s your special filly thing to do. I know I never felt like sticking my butt in your direction.” “Yeah but it’s... I mean, you’re okay with it?” Blue asked, her ears straightening as she looked at him. “I think it looked... really good,” Purple said honestly, “And it was making my penis really tingly. So try doing it again. Maybe you’ll feel good?” She did so in a heartbeat. “Oh man this urge is *weird,”* she moaned, swaying her hips as her nethers winked again. “I... I can just show you, ‘cause I’m feeling the urge hehe,” she said a little drunkenly. “I... I’m feeling an urge too,” he said. “Really?” she asked, looking over her shoulder. Purple was nosing under her tail though. “You smell... incredible,” he added. “Did I smell this good down there?” “I... I dunno,” she said stupidly, loving even just the feel of his breath on her sensitive labia. Then his tongue hit home. A few breathless gasps, and he released her from that paralysis of instant ecstasy, saying, “Heh, feels pretty good for you too, huh?” “You licked it!” she squeaked in shock. “Just like *you* licked it,” he countered, “I felt an urge to lick it. So present your urge and I’ll lick you and... something with my penis.” The filly melted into his affections, until Purple pulled back enough to say, “Your labia is wetter than my tongue!” “I wanna be *so* wet,” she moaned eagerly, “To make lubrication and... something.” “Why are we even doing this?” he asked, “I don’t want you to lick me more, but I wanna feel good in my penis, and I don’t know what I want, even.” “W-well, the... instructions, maybe?” she asked, blushing shamefully. “It just felt so good, I forgot you just felt your tongue. My labia feel *way* more *super* incredible than my tongue.” They looked at the instructions, and Blue said, “Oh, gosh! Yes, that makes sense. When the female presents for the male, her... winking, and her scent will increase his arousal, until he feels an urge to mount her. Oral stimulation is hightly recommended, to strengthen that urge as much as possible. So when you were licking me, you were getting the urge to mount me!” “And that’s the first section of coitus,” he replied, turning to that section. “*Ohh*,” he concluded immediately, “So that’s why the male mounts his female.” Following his indicative hoof, Blue read, “Mounting allows the male to insert his penis inside the female’s vagina. Uh, what’s a vagina?” “It’s probably just another fancy name for pee place,” he said casually, “But see in the diagram, how his penis’s just sticking into her? And it’s all big and stiff?” “Oh, ohh!” she realized, “So it must just be drawn wrong. You wanna... slide your penis under my belly I guess?” “I dunno, but it’s worth a try,” he said, “Lemme lick you and oral stimulate you until I really feel that urge.” “W-we should read the rest before we start again,” she said tentatively, “But I really wanna do that, yeah.” They did, and were glad they did so. “Oh, so I’m gonna get the urge to slide, in a thrusting motion. I guess that could happen?” Purple said puzzled. “It’s to stimulate you to ejaculate,” she said, reading further, “So like my hoof rubbed you to make you erection, now my...” She peered uncertainly at the diagram, “You’re gonna slide it under my belly, I guess, and rub it in there.” “Huh, the flare sounds... weird,” Purple said, “It says at the height of my arousal, the tip of my penis will expand, sealing off the mare’s womb to optimally inseminate her.” “What’s inseminate?” Blue asked. “You got me,” he shrugged. “Okay, and the climax...” she said, looking at it, “A peak hormonnal storm that stimulates the meduhlla...” “Let’s just figure it out,” Purple said impatiently, standing up, “I wanna try sliding my penis under your belly and licking and stuff.” “Okay,” she said, “And I wanna present for you, and get licked, and... you ejaculate I guess.” “All I know is it’s a thick fluid, and it isn’t pee,” he replied, “It’s like your slimy girl stuff, but it comes out of the hole in the tip of my penis.” “Makes sense,” she said, “So um...” With a barely suppressed giggle, she turned tail, and presented for him. “I’m getting urges,” she said in delight, “Just wanna show you my butt all day, ‘cause I’m receptive.” He didn’t even hesitate to start licking, and Blue’s hind legs stiffened again, even as she breathed deeper and deeper. It felt like something was building up in her, these tingles of pleasure that radiated from that tongue plumbing her groin, growing bigger over time. Any inhibition she had was long gone, and it just felt like the most normal thing in the world to turn her tail aside while her friend licked her labia. She was starting to get nervous with how good it was feeling. How good could it possibly feel? It just kept getting more and more! She was just on the edge of something, when her friend stopped licking and immediately climbed up on her rump. Blue moaned at that, and Purple asked, “What’s wrong?” “Nothing!” Blue protested, looking back at him, “It feels good. You’re just... heavy on my butt, and you slid your hooves right up along my flanks!” “Yeah, just to grab your thighs,” he said uncertainly, “Your flanks are...” “*Really* tickly, and I want you to touch them,” she said, facing forward again. “So do your urge thing, start rubbing your penis or something. I wanna feel that again, between my legs it was like... tingling fluttery something.” Purple did, and quickly found he could nestle his penis right in her labia. “C’mon, start sliding~” Blue moaned, “You’re just teasing me with your penis just pushed against me!” He did start sliding, and his penis wouldn’t curve right to conform with her belly. But Purple *really* felt the urge to keep thrusting, trying hard, until Blue protested, “Figure something out! This isn’t working!” “Well I dunno,” he said, “I liked when I um...” again, he pressed his tip against her labia. “That feels... good,” he said, uncertain at the satisfaction. “Try rubbing *just* there,” she panted, “That feels really... important back there. Just gonna squirt thick fluid outta your penis...” He tried, but there wasn’t much room to rub. Purple was about to protest again, when he pushed up into a deep fold within her labia. A deep fold, that when he pushed deeper, just sort of wrapped around his penis. “H-how far do you go in?” he asked in amazement, as he pushed deeper, finding the flesh around his penis almost burning hot. “I don’t know!” Blue squealed, “I feel weird! It’s... really stretching me back there!” “I’m gonna see how deep you go,” Purple said with determination, pulling her thighs to slide his penis up deep. He was shocked when he just slid smoothly in that ovenlike slimy passage, surrounding his penis with a strange bumpy texture, that kept moving around him. “Oh *Celestia* that’s deep,” she gasped, “I dunno if I can *go* any deeper.” “The instructions, look,” he said in wonder, and thankfully the instructions were open to the cross section of the stallion mounting the mare. “That’s why his penis was sticking inside her. Because it was!” “T-that’s me...” she said, trembling with need, looking at the book, “You’re in my... vagina it says.” “Maybe your inside place is a vagina,” he pondered. “And my outside place is a labia?” she asked, “Makes sense. Are you gonna... go deeper in my vagina?” “I... I can’t push deeper,” he said, “I need to... it says I’m gonna feel an urge to thrust.” “Move in and out,” she continued intensely, “Until you orgasm.” “I don’t feel an urge, but I’m gonna try...” he said, sliding out as she hissed at the feeling of collapsing and relaxing in the wake of his penis. “Oh *wow,”* he exclaimed, sliding in *deep* again. “That feels so good...” “My vagina feels so good!” she crooned in reply, “You’re sliding in it and stretching me so deep again!” “C-can you feel... where the tip of my penis is?” he asked cautiously, hugging her rump. “Yeah,” she said thoughtfully, “Like all the way up to my *belly button.”* “That’s where I’m gonna ejaculate,” he replied, “A thick fluid out the... hole in the tip. I guess you have an urge to let me just... put a bunch of goo up there?” “Ohh I dunno, it’s already so gooey in there,” she griped, “Just don’t worry about it. I bet ejaculating feels *even better.”* Purple pulled out again, and pushed in, giving a few more experimental thrusts, then he fell into an ancient, primal rhythm, blowing Blue’s mind by thrusting into her again and again. Then... he stopped! “No, don’t stop! I need it!” she squealed in protest. “I was thrusting,” he said in astonishment, “That’s what the urge is. It just makes me keep thrusting and thrusting, like over and over again.” “I feel the urge too,” Blue bit out, her piked hips tight to his, “I need you to thrust more and more. My... my inside needs you to!” He thrust once, and she said, “Yes...” then again, and she moaned, “Yes~ please more I need it.” Then they were fucking like a couple of horny bunny rabbits. “What’s happening to me? I want your penis so bad,” she moaned in urgent need, needing his thrusting more than anything she had ever needed in her life. She orgasmed so hard it took her by surprise, squealing as the pleasure that rolled through her in climactic waves didn’t even seem close to ending! And he kept thrusting, this was amazing! It did end eventually, and she was a simple animal of need by then. Her insides felt powerful, armed and ready, eager, and his penis tingled more and more every time he plunged into that ovenlike warmth. All he cared about was pushing into her slick oven, and the urge in her was overwhelming to stand here, lift her tail and get his penis thrusting. “It’s...!” he said, as the tingles grew so powerful, even the slightest thrust made him feel like he was being electrified, “Blue it’s... I’m gonna ejaculate!” “You are?” she gasped anxiously, “I... I want it! Please hurry. I just have to stand here and... and hold your penis into my vagina, and that’s all I can do, Purple. My whole butt is... h... hungry for you...” He fucked her hard until it overwhelmed him, and an orgasm swept over *him* as something... happened. His penis started flexing over and over again, to the rhythm of the strange squeezing of his friend’s inside place earlier. Something just rushing up his thick shaft, while his friend felt it blast into her. At that, Blue cried out, “Aaah, it’s hot! I wannit! My butt’s hungry! Aah! Aah!” Semen just burst up into her, flowing into places she didn’t even know she had. All she could think of was how she was standing there, pressing her butt back against him, so his penis would slide so deliciously deep, and she could feel her big hungry, female butt filling up inside with Purple’s wonderful seed. It was the most important thing in the whole world, and she could think of nothing else other than what was happening to her right now, to her inside place, her vagina, and the semen pumping out of his penis. He clenched his teeth with the unstoppable urgency as his throbbing dick pumped his friend’s womb full of seed. She didn’t even try to conceal how much she wanted it in her urgent cries of relief and need, standing there while her friend just grabbed her hips and pumped *semen* into her back there. Her tail was so high she was surprised it didn’t fly off her butt. Her whole body was flooding with pleasure, and the semen was filling her inside! And... something was happening to her. “I feel strange!” she exclaimed, as that heavy seed within her just seemed to flow throughout her whole body. Her eyes were dilating, though she didn’t know it. “This’s weird,” she said, “Your sehmen is making me feel funny. My insides are all... fuzzy...” Then a giddy laugh rose in her, as Blue felt like she won the most incredible prize ever given. She was changing into a... semen holder, not just a filly. She had a special place, that wanted semen. And it... it had it. She felt like her legs were for pushing back to get the semen deeper. Her inside place was to stroke him to make his semen come out. Her head was to think of how to get semen inside her. Even her tail was made for turning aside and presenting her butt, to get it full of semen. And she was. She kind of collapsed then, Purple laying atop her, still sealed inside with his amazing flare. They both were humming in delightful satisfaction and pleasure. “You okay?” he asked, breathlessly. “Your sehmen’s changing me,” she said in drunken delight, “It’s so warm and full inside me. I wanna take care of it and keep it safe in there. I–I’m your friend, and I’m the place for your sehmen to go now. I want all your thick fluid inside me. You’re cuddling me, and your sehmen is making me cuddle it inside. Because that’s what I do now, is cuddle sehmen. That’s me.” “I don’t think I need to read a book to know about the cuddling,” Purple said, squeezing her into a penetrated hug from behind.
