Chapter Before the Following Chapter

"Spike... what are sects?" Sweetie Belle asked.

The young filly and equally miniature dragon were sitting alone, together, in one of the lonely supply rooms at the Carousel Boutique--specifically, the yarn storage. Rarity kept telling Sweetie Belle how she was sure that oversized, lumpy, yarn-based sweaters would soon enough become the hit fashion of all of Equestria... but it'd been four years since the big yarn buyout, and so far most of the supplies had just been sitting around gathering dust, waiting for the big ugly Hearth's Warming ugly sweater revolution to take place.

"Uh... sects?" Spike scratched his head. He and Sweetie were sitting on one of the boxes in the corner, a place away from prying eyes and as much privacy as a young couple could ask for. No matter how often the two of them disappeared together, nopony ever seemed to look for them in here. "Hmm... I think I remember hearing that word in one of Twilight's reports. Sects..." Spike scratched his head again. "Do you mean like groups or tribes of different types of ponies?"

Sweetie Belle shrugged. "I dunno. I don't think so. I just heard it's what older ponies do when they're in love."

"Oh." Spike blushed slightly. "You mean, uh... sex?"

"Yeah, I think so." Sweetie smiled and shuffled closer to Spike, pressing her body into his.

A bead of sweat rolled down Spike's forehead slowly.

"Um... I've heard of it before, but I don't really know what it is."

Sweetie appeared to be half-listening as she studied a spot on Spike's ear. She nuzzled her face into his neck, feeling the cool sheen of his scales against her fur. Spike was blushing even harder now, and Sweetie beamed.

"Oh, geez..." Spike shuffled uneasily on his box-seat. Sweetie was always finding new places and ways to make him feel strange and tingly inside. Now she was nibbling on his neck, and jolts of tiny electricity seemed to shoot up his spine each time her lips made contact with his scales.

Sweetie kissed all the way up to Spike's forehead, then planted her mouth squarely in front of his.

Spike gulped nervously. "I'm still not very good at this," he said.

Sweetie giggled and put a hoof to her mouth.

"Who told you that, silly? I happen to think you're really good at it."

"You mean kissing?" Spike asked.

Sweetie nodded. "Uh-huh. You make me feel all warm and sizzly inside... Come on. Let's do it some more."

Spike didn't need to be asked twice. Even as unsure as he was, his claws still seemed to fit so naturally on Sweetie's shoulders, pulling her close to him as their mouths met. Spike liked to start slow, and gentle, but he could only squeeze in one or two gentle pecks on the lips before Sweetie pulled him close, hard, and smashed her lips into his, pressing and grinding her mouth into Spike's like she was hungry for something only he could give her. Then the tongue would come out, and before Spike new it he was in a whirlwind of back-and-forth, kissing and squeezing his body into Sweetie's, the two of them running their hooves and claws along each others' backs, the two of them grinding their bodies into each other absent-mindedly, rocking back and forth on the box as they made out.

As usual, it only took a few minutes before both Spike and Sweetie felt very unusual.

"Look, it's doing it again!" Sweetie said, stopping to wipe a bit of saliva off her mouth with her foreleg.

Sure enough, Spike's penis was rising to attention, pointing straight up in the air. Suddenly, it seemed like it wanted attention.

"Um. Sorry about that. It still just kinda, uh, happens..."

"It's okay. I get stuff like that too. My, uh, between parts... my cunny, uh... get's all wet, when we kiss. So I think it's normal, probably."

"Oh... yeah." Spike fidgeted nervously in his seat, half-hoping to conceal his hard-on, but also for some strange reason hoping that Sweetie would touch it. Hoping but not knowing what would happen--only that it would be really, really good.

The two of them stared at Spike's erection for a moment. The air in the room was thick, tense and full of the smell of premature hormones.

When the door opened without warning, both Sweetie and Spike froze. There was only one pony who would be looking for yarn at this hour.

"Now, where did I put that rural collection? I've been waiting over a year to do something with those pumpkin hues..." Rarity strutted into the storage room like she owned the place (which, she in fact, did). It took her the better part of five seconds to notice there was more than yarn inside the room.

Her eyes fell on Sweetie Belle. Noticed how close she was to Spike. Fell on Spike. Noticed his claws folded together in his lap to hide his unfortunate... excitement. Did some slow math in her head, putting the pieces together, finally understanding where Sweetie had been spending so much of her time the past few months, and why she always seemed to smell like emeralds when she came home...

"Oh. My goodness."

Spike glowed crimson and bunched his claws tighter together over his lap. The head of his erection still managed to peek out behind them.

Sweetie clung to Spike and let her head sink until she was staring at the floor. This would most likely not go well.

"Um... well. I guess that's why I've been seeing so little of you lately, isn't it, Sweetie? You've gone and gotten yourself a young dragon suitor, haven't you?"

"Uh... I guess?"

Sweetie was blushing too, pink cheeks glowing in compliment to her fur.

"Oh, Sweetie, please don't be embarrassed. I was caught many a time in my youth in similarly... compromising positions. I'm just delighted to learn you've gotten your first taste of... *l'amour*."

"Huh?"

"Love, Sweetie Belle."

"Oh. Um... yeah, I guess."

Sweetie and Spike looked into each others' eyes, blushed, turned away, and then faced each other again, desperately longing for the kiss they weren't sure belonged in front of Sweetie's older sister.

"And I'm certainly not one to stand in the way of young love. So, I suppose, I'll just grab my yarn and, um, leave you two to your... explorations, shall we say?"

Spike and Sweetie both nodded, mute.

Rarity smiled.

"Very good then. I'll just... take this and, um... one of these..."

"Rarity?" Sweetie asked, voice tentative but clear.

"Oh! Yes, Sweetie Belle?" Rarity turned to look at the couple again, making painful effort to not stare at Spike's still obvious and irrepresible excitement.

"What are sects?"

"...sex," Spike mumbled under his breath.

"Oh, right! What are sex?"

Rarity blushed a bright crimson for a moment.

"Oh, my word. I had no idea you two were... then again, when I was your age, I... not with quite the same company, of course, but there were a lot more opportunities for a young filly your age in the city at that time... oh, good heavens. Well, I suppose you are at that age of curiosity, when the inklings of affection in a young pony turn to... lust, and other complicated things. My goodness."

"Do you think that means she's not gonna tell us?" Sweetie whispered to Spike.

Spike shrugged.

"Well. I must say I'm very impressed that you came to me to ask that question. Or... rather than you asked it, regardless of the circumstance. And sex is a... very complicated subject, I should say. But there's no reason it's not something you can learn with the help of your big sister. And as your guardian, I will make it my absolute duty to educate you in the nature of love from here-forth!"

Spike and Sweetie shared a look.

It said, 'What have we gotten ourselves into?'

The Chapter You Are Currently Reading

Dragged along by Rarity, Sweetie and Spike found themselves seated nervously at the foot of her four-poster bed. Spike fidgeted nervously with his claws and tried not to feel uncomfortable on the elegant blankets and bumping against the billowy sequinned canopy that cascaded down from the top of the bed. Sweetie looked nervous too, but she shuffled closer to Spike on the bed and gave him a nervous grin. Spike managed to smile back.

Rarity, who, since she'd stumbled through the door to underage makeouts, had been running around like a pegasus with a ginger root shoved somewhere inconvenient. She darted from drawer to drawer, mumbling things like "must use protection, where did I..." and "no, but then again, unless it's both ponies..."

Spike and Sweetie sat patiently and politely as long as they could. Eventually, Sweetie cleared her throat awkwardly.

"Uh, Rarity? What are we supposed to--"

"Oh, goodness! I suppose I was getting a bit absent-minded. But, then again, time passes so quickly in the heat of lust..."

"What is she talking about?" Spike asked.

Sweetie shrugged. "I think it has something to do with sects."

"Sex?"

"Yeah, that."

Rarity, somehow finally content that she had scoured every inch of the bedroom for necessary materials, turned to the young couple on her bed and beamed.

"Now, of course, it's natural, at your age, to have many questions about... the different ways our bodies can respond to affection, shall we say. And at this point, I must ask, no need to be embarassed, of course, we are in polite but nevertheless non-discerning company... um... Sweetie, Spike... what have the two of you been up to these past few months?"

Spike and Sweetie both blushed, but Spike the brightest. They shared a glance, and Sweetie swallowed the lump in her throat before beginning to speak.

"Well, we kiss, a bit, and hug, and sometimes when we kiss for a really long time both of us feel kind of excited, like something's supposed to happen but we don't know what. Spike's, uh, thingy, get's really long and hard, and my, uh, cunny, between my legs, gets really wet, and it feels all tingly and stuff... but then we don't know what to do next."

Rarity nodded, eyes closed, an almost motherly peace on her face.

"Well, that all sounds perfectly reasonable at your age. Dare I say, a few years younger and I was making more than a few colt-friends with whom I may have spent the weekend... Nevertheless! It's very sweet, both of you, that you felt safe enough to come to me for help."

"You kind of just opened the door when we were--"

"Now, the first and most important thing to establish, when spending time with somepony (or dragon) that we care about... is what is okay and what is not for us to do together."

Sweetie and Spike blinked.

"What do you mean?" Spike asked.

"Well, my dear Spike, in the realm of love and affection, there might be many many activities we could partake in with our partner. Gentle, soft expressions of affection, like strolling through a flower garden in the evening, or waking up next to each other and cuddling under the warm quilt. It could be much more intense, like seeing my partner after two weeks away and kissing them so hard it makes them see stars. It could be almost violent and dangerous, ripping off somepony's designer gown and throwing her on the canopy bed to ravish her like a conquest of war..." Rarity's eyes began to glaze over as she stared somewhere farther away than the present.

"Rarity?" Sweetie asked.

"Oh, yes! But before we start any of that, we must establish consent. 'Consent' meaning simply, that you're both okay with what's about to happen, and if at any point things become uncomfortable or unpleasant, you must simply say "Please stop" to have things pause for as long as necessary."

"Why would we want things to stop if they were feeling really good?" Sweetie asked.

"Because the comfort and enjoyment of both participants is important, Sweetie Belle. If Spike is having fun but you're not, it's not very likely the two of you together will feel much love afterwards."

Sweetie and Spike blinked again. So far, sex was very confusing.

"Let me try to simplify," Rarity said. "If you meet somepony--or some dragon--with whom you'd enjoy spending time, and you ask them if they'd like to see you, on a date or just to hang out, and they say 'No'--that's it. Give them their space, and take them at their word."

"But Sweetie asked me to leave her alone all the time before we started, uh..." Spike looked nervously at Sweetie, who was smiling sweetly at him. "Sweetie... are we dating?"

Sweetie blushed and looked down, but then back up, still grinning. "Um... yeah. I think we are."

"Oh. Okay. Cool."

Rarity sighed.

"Yes, well, certainly old-fashioned courtship can look a little bit like pulled braids on the playground... but please, both of you, don't assume your partner is saying anything they don't mean. We'll talk about establishing rules for this as we go on."

Sweetie and Spike nodded.

Rarity took in a deep breath before she continued.

"Now, since I've only seen the two of you, er, in a minor state of affection... I'm lead to believe there hasn't been much more between you that's taken place? No... putting of something into somewhere else, or touching the something of something to make it feel very good?"

"Huh?" Sweetie asked, head tilted.

"Oh, let's just move on with it. Sweetie, Spike, please show me how the two of you kiss."

"You want us to kiss in front of you?" Sweetie asked, her face scrunched.

"Goodness and heavens, Sweetie, I'm your elder sister. If you can't trust me to watch you share your love with a partner in a non-judgemental fashion, I don't see how we'll ever make it through the rest of the lesson."

"Come on, Sweetie," Spike said. "I've never heard you complain about kissing before."

Sweetie blushed. "Alright, fine." She wrapped one foreleg around Spike and yanked him close before he had a chance to respond. She was just about to plant her lips on his when--

Rarity's hoof plunked between the pairs' lips.

"Consent, my dears! Is this kiss perfectly alright? Just ask once, and everything will be fine from then on. Just listen carefully to your partner and take them seriously if they say they need things to stop."

"It's just a kiss," said Spike. "What's the big deal?"

"A kiss can lead to very overwhelming emotions and sensations, Spike. Which is why even if we feel ourselves being swept away by how good something feels, if our partner is uncomfortable, we must always stop and check on them."

"So what are we supposed to say?" Sweetie asked, more eager to just get on with the kiss than Spike seemed to be.

"Something like "Is it alright if I kiss you?" would be perfectly fine."

Sweetie sighed.

"We were making out like, ten minutes ago. Why do I have to ask to kiss him now?"

"Because if Spike had gotten too nervous or uncomfortable in those ten minutes, he deserves the right to take a breather and control the situation as much as you."

"Does this mean I'm not allowed to just, sneak up on him and start making out, like we used to?"

Spike blushed.

"Well, that depends. Spike, do you enjoy Sweetie Belle sneaking up on you, and, er... making out?"

Spike blushed even brighter.

"Uh... yeah. I like it... a lot."

Rarity beamed, and Sweetie smirked.

"Very good! Then as far as is necessary between the two of you, consent is established. And Spike can at any point revoke his consent if his needs or feelings suddenly change."

"Sex seems like a lot of work so far," said Sweetie.

"I guess it's sort of like taking lessons before you get your carriage license though," said Spike. "You test all the bad situations first to make sure you're prepared for them. And even if you never run into them again, you feel better knowing you're ready."

Rarity smiled brilliantly and clapped her hooves together over her head.

"Exactly! Our young dragon has grasped the gravity of the situation entirely."

"Uh, Rarity? So... do you want us to make out, or..." Sweetie asked.

"Oh, good heavens. Yes, I think we've done enough to establish that consent. You two go at it."

Yes, it did feel weird, the idea of kissing your boyfriend in front of your big sister. But Rarity had been so kind and accommodating, it was almost easy to just forget she was there, put one hoof around the bundle of green and purple scales next to her and just drag his mouth to hers. Before she knew it, Sweetie was in full-blown tongue-kissing mode, letting spit drip from her mouth and onto Spike's as the two of them ground their bodies into each other. Everything was hot, so hot, Sweetie felt a wetness between her legs again, and Spike was rocking back and forth next to her, his erection rubbing insistently against the fur of Sweetie's leg.

They probably wouldn't have stopped unless Rarity made them.

Sweetie was panting as she drew back from Spike, a bit of saliva still dribbling from her mouth. Spike looked just as winded, not quite as flush. Both were blushing, and rocking their bodies ever so slightly against each other, begging for more pressure, more touch, more attention somewhere that desperately needed it...

"Now, I can see you're both very very, um, invested in this activity now... so it's important we take as little time as possible to explain things so you can get back to your, um, 'fun'. Is this the point, Sweetie, you were mentioning earlier, when everything gets hot and wet and wants to be touched?"

"Uh-huh." Sweetie rocked back and forth on the bed, clenching her hind legs together, pressing her hooves into her lap and rocking her blank flank back and forth on the bed.

"And Spike, this is the same for you, with your, um, soldier standing at full attention?"

"Huh?"

Rarity put a hoof on her forehead. "Your penis, Spike. It's fully erect, isn't it?"

Spike glowed crimson. "Oh. Um... yeah. It, uh... it is."

"Wonderful! Then it's time for part two of our lesson. And I'm lead to believe that despite all your time together, the two of you have never gone further than this?"

Spike and Sweetie shared a look and nodded.

"Uh-huh", Sweetie said. "I always wanted to touch it," she said, pointing to Spike's hard dragon cock, "but I guess I was too nervous..."

"Well there's no need for nerves to day, Sweetie. We're here to learn about love, after all. So why don't you just go right ahead and follow those instincts?"

"You mean I should touch it?"

"If it's alright with Spike, that is."

Sweetie looked at Spike, who's eyes were hungry than she'd ever seen them. His legs were splayed and his cock pointing straight up at the ceiling. It was bright pink, with purple and green accents to match his scales.

"Spike... is it okay if I touch your, um... penis?" Sweetie looked to Rarity, hoping she'd used the right word.

Rarity nodded, but said nothing.

"Uh... yeah. Sure," Spike said.

Sweetie tentatively raised a hoof and began to move it towards the tip of Spike's erection. His cock twitched nervously as her hoof neared, until finally it touched the side and began to slide slowly down to the base, rubbing just once or twice up and down.

Spike groaned immediately, and bucked his hips to shove more of his cock into Sweetie's hooves.

Sweetie gasped, and almost backed off the bed. She'd never seen Spike like this before... so enthusiastic, so carried away. She wanted to touch him again.

"That felt good, didn't it, Spike?" Rarity asked.

Spike nodded and groaned. "Yeah," was all he could manage.

Sweetie, now realizing she had full permission to touch as much as she wanted, began to do exactly that. She took her other hoof and placed it on the opposite side of Spike's cock, then began to press her hooves together and drag them up and down. She hadn't seen anypony do this before, she'd never touched a cock or even imagined what they might feel like until now... and yet, somehow, it just felt right, like she knew exactly what to do with herself to make the tiny little dragon sitting next to her explode with pleasure. Which it certainly looked like he was doing.

"Ohmigosh... Sweetie, that feels..." Spike's words were blurring together, his voice trailing off as he let himself give into the sensation of Sweetie's tiny hooves stroking his cock. He'd touched himself a little once or twice before, nothing serious, just figuring out what it felt like if he gave himself a little squeeze... but nothing like this. Already, it felt like something strange and wonderful could happen any moment.

"Sweetie," Spike said, his voice catching. "I feel... I mean I think I'm gonna... oh, jeez..." Words began to falter as Spike moved his hips more and more in succession to match Sweetie's strokes. Sweetie stared at Spike as she stroked, her eyes wide, tongue hanging out just a little, watching her boyfriend transform from a nervous kissing partner into someone completely overtaken by pleasure. She felt like a Goddess.

"I think young Spike is about to reach the finish line, so to speak. Are you alright with him getting you a bit sticky, Sweetie Belle?"

Sweetie didn't know what Rarity meant, but she didn't care. She was hungry, starving, she wanted more of this and more of Spike's cock and more of his tiny moans and noises and bucking against her hooves... she wanted more of everything. Her cunny was soaked, between her legs leaving a stain on the bed-sheets already. Celestia, she wanted it so bad, and she didn't even know what it as.

"Yes," she said. Just "Yes".

Spike looked to Rarity for guidance, who simply winked at him, bobbed her head, and mouthed the words "go for it".

Spike came. He bucked his hips and howled and shot the first and biggest load of cum of his young life all over Sweetie Belle--her hooves, her forelegs, the pristine white and pink of her fur--Spike came so hard he fell back on the bed, and his jizz shot out like a cannon, painting Sweetie with his full load before dribbling the last two shots down the side of his cock, lubing it up more as Sweetie stroked the last drop out of his balls. Her face was wide, mouth open, shocked, but she kept stroking, until Spike held up a claw and Rarity gently removed Sweetie's hooves from the still erect dragon-dick in front of her.

"Uh... wow." Sweetie said. She held a hoof up, and examined the sticky white goop dangling from it. "Is that, uh..."

"Yes, Sweetie. When boys get very excited, they tend to make a mess like this. That's called their 'cum'. It's something boys and girls both do, but with boys, it's often a bit harder to clean up. Of course, girls aren't always the tidiest either..." Rarity spared a glance at the bedding under Sweetie's legs, which had already begun to soak.

"I take it after that you'd like a bit of attention as well, Sweetie Belle?"

Sweetie nodded readily, clenching her legs together in an attempt to quell the burning feeling begging for attention. "Uh-huh," she said, then looked at Spike. He seemed embarrassed, not ready to meet her eyes at first... but then when he looked again, and saw his girlfriend sticky and coated in a load of his jizz... he couldn't help but stare, and let his erection grow until full size again.

Sweetie stared open-mouthed, but came back to reality as Rarity tapped her shoulder.

"Now, I imagine you're very wet between your legs right now, aren't you, Sweetie?"

Sweetie nodded. "Uh-huh. Is that bad? It feels like I hafta pee, sorta."

"Not bad at all. That just means you're ready to feel good, the same way Spike was, when his dragonhood enlarged to full size. When fillies get excited, their parts get very wet to make it easier to slide something inside. Now I wonder if there's something long and hard that would slide in-between your legs easily..."

"Ooh, ooh, Spike's cock!" Sweetie said, raising one foreleg in the air like she was answering a question at school.

Spike blushed and tucked his head down. But Rarity smiled at him, and he managed a soft grin back.

"That's exactly right. Now, since Spike's gotten some attention before the main event, it seems only fair that we learn a little bit about Sweetie's special place as well before the, um... main event, so to speak. Now, Spike, when Sweetie was stroking your cock--and it is a 'cock', the proper adult term for it, if you'd like--it felt quite good, didn't it?"

"Uh-huh," Spike said, nodding. His cock twitched ever so slightly.

"That, as it turns out, is the basis of 'sex', as you were asking about... everypony has a special place that makes them feel good, and if you find somepony you really care about, you can spend as much time as you want making each other... er, helping each other... well, you can both feel really good as much as you want, I suppose. As long as you're doing so *responsibly*."

Spike and Sweetie shared a look that said something like "We can do this together as much as we want?"

"Now, Spike, since Sweetie was kind enough to give some attention to your excited spot, perhaps it's time we return the favour. Do you think you could place one of your claws gently between Sweetie Belle's hind-legs?"

Spike nodded.

"And Sweetie, this is alright with you? If at any point you become uncomfortable, you just let us know, alright?"

Sweetie nodded too, but didn't look like she was listening very much. She was staring at Spike's claw, and rocking back and forth on the bed.

"Go ahead and spread yourself then, Sweetie, so it's easier for Spike to see."

Sweetie blushed, but followed instructions, lying back a bit on the bed and spreading her hind-legs so Spike could see her cunny. She was soaked, dripping down onto the bed-sheets and probably soaking into the mattress. She was hot, too. So hot.

"Wow," Spike said, lowering his head to get a closer look at Sweetie's slit.

"And as we've learned the correct word for your equipment, Spike, this is Sweetie's 'pussy'... and it will feel very good for her if you give it a little lick, just along here..." Rarity pointed one of her hooves to the top of Sweetie's hole, and dragged it along just a little, making Sweetie shiver uncontrollably.

"Right there?" Spike asked, pointing a claw to Sweetie's covered clit.

"And around too, dear. Don't be too fierce, and be sure to explore all around. Gently."

Spike nodded, took a deep breath, and lowered his face to Sweetie's cunt. The warmth and wetness were unlike anything, and for the first time, he connected the smell of arousal perpetually present during their makeout sessions with the actual physical arousal of Sweetie's sex. She wanted him badly, and he could tell just by the way his claw seemed to slide smoothly along her lips, by the way her whole back arched when he touched her ever so slightly.

Following Rarity's advice, Spike leaned in and lapped against the hood of Sweetie's clit.

"Oh, gosh!" Sweetie squealed and bucked her hips up towards Spike's mouth, rubbing her wetness all over his face.

Spike was taken aback at first, but managed to collect himself and dig in with more gusto than before. The taste and scent in his mouth overpowered him, and he began to lap, almost drunkenly, at the banquet of filly pussy in front of him. Sweetie thrashed and met his licks with moans, hooves grasping at the bed-sheets as her eyes clenched shut.

"Ohmygosh, ohmigosh, ohmigosh..." Sweetie started mumbling under her breath. Spike hadn't let up since he first buried his face in her cunny, and his tongue was so big and long and wet, and seemed to keep hitting her in the right place over and over again. Oh, something was coming, something big was going to happen...

"Spike!" Sweetie Belle managed. "I feel like... I think I'm gonna..."

"Go ahead," Spike grunted between his teeth before shoving his face and tongue back to work on Sweetie's underage hole.

"Oh... I'm..."

"That's it, Sweetie," Rarity coaxed. "Now you can 'cum' too." She smiled.

Sweetie clenched her whole body as her orgasm hit her. It seemed to move like a wave of lightning, starting between her legs where Spike's magic tongue was, then surging upwards, hitting her everywhere she didn't know she wanted to be touch, lighting her cunny on fire, her tongue wanted more makeouts, her hips couldn't stop bucking, please, she wanted more, she wanted more of this always...

Spike seemed like he would have kept going forever, but Rarity pulled him backwards just as the crest of Sweetie's orgasm seemed to arrive. She smirked as she watched the young dragon and filly ache for each other, Spike's erection throbbing between his legs, begging for access to Sweetie's dripping hole.

"Very good! Now we've gotten consent out of the way, and understand the general basis of where to touch each other to make things feel good... I suppose that leaves only the main activity left."

Sweetie and Spike shared a glance.

"You mean sex?" Sweetie asked.

Rarity nodded and beamed back at her.

"If the two of you are ready, I think that would be quite a good idea."

"Sweetie," Spike began, "are you sure you're..."

He stopped, mid-sentence, as Sweetie lay on the bed in front of him and spread her legs, letting him get a full look at her wide-open dripping cunny.

"Uh..." he said. His erection throbbed painfully between his legs.

"Let's do it," Sweetie said, smirking. She raised her hind legs even further and held them back behind her head with her hooves.

"My goodness, Sweetie... where did you learn a position like that?" Rarity asked.

Sweetie blushed, but held her 'fuck-me' pose perfectly. "Uh, well, I think I saw it in one of Big Mac's magazines that Applebloom showed me one time..."

Rarity shook her head. Fillies growing up faster every day, it seemed.

"Well, I dare say you're quite ready to go. That just leaves our young dragon. Spike, are you feeling ready?"

Spike nodded and gulped. "I think so." He looked at Sweetie, who was still spread-legged. He tried not to stare at her wet, dripping pussy, failed, and managed to drag his eyes back to Sweetie's face again. Her eyes were wide, and she was smiling. "You sure you're okay with this?"

Sweetie rolled her eyes and sighed. "We already did that part. Yes, I consent, it's fine, I wanna get fucked, gimme that dragon dick!"

Spike and Rarity both went wide-eyed.

"Well... You heard the lady," Rarity said, after a moment, smirking.

Spike gulped again, then sized himself up, taking his position above Sweetie Belle. His cock seemed to dangle nervously between them, hovering above Sweetie's cunt as he positioned himself. Even though he'd never done it before, the angle seemed to make sense on its own, just line the tip up here, rub once or twice to get it wet, and then sliiiiide forward...

Sweetie gasped. Spike groaned. Sweetie's whole body seemed to shake as Spike's cock slid inside her, inch-by-underage-inch, until at last the dragon and young filly were fully joined, their first fuck under Rarity's watchful eyes.

"Uh... are you okay?" Spike asked, half-groaned, from behind clenched teeth. He wanted to move so bad, but still remembered the pretense of the lesson from earlier.

"Uh-huh. I'm... okay. Are you okay?" Sweetie asked, gritting her teeth, begging her body not to buck her hips up and down over and over again, to slam herself into that dragon dick she had been aching for...

"Uh.. yeah. I'm... okay," Spike said.

A few seconds of silence passed.

"Well, what are the two of you waiting for? This is the real deal. Have some fun!"

Spike and Sweetie shared a look. A small nod.

Spike had no sooner began to move his hips back than Sweetie moved hers forwards, barely letting an inch of Spike's cock slip out before he began thrusting back in. It took a few thrusts, but pony and dragon seemed to find a rhythm together. Sweetie let out a soft squeal every time Spike buried his dragon cock in her underage cunny. And Spike clenched his teeth, letting out tiny grunts every other thrust.

"Keep in mind that conversation doesn't need end simply because you've began to feel good," Rarity added, seemingly out of nowhere. Spike and Sweetie both jumped a little, but were too busy in the middle of fucking each other to be actually surprised.

"What... do you mean?" asked Spike, pacing his breathing between each thrust.

"Well, it can be very fun for your partner if you let them know what's feeling good and what isn't. You can just ask, for example, something like "Sweetie, is that feeling good?"

Spike gritted his teeth and stared down at Sweetie Belle, whose mouth was hanging open, her tongue just a little bit out of one side. Every few seconds she would close her eyes completely and tilt her head back, whimpering softly with each thrust of Spike's cock.

"Um... Sweetie, is that feeling--"

"Yes! Gosh yes, Celestia, yes, please keep doing that, Spike... Please, keep, uh..."

"Fucking, is the word you're looking for, Sweetie."

"Yes! Please keep fucking me Spike, oh gosh, it feels so good in my cunny, I love it, I love your cock, please, please Spike..."

Spike wiped a claw along his forehead, discarding the cascading beads of sweat that had begin to gather there.

"And it feels good for you too, Spike, slamming yourself into Sweetie's pussy like this?" Rarity, unbeknownst to either underage participant, had started touching herself beside the bed, rubbing one hoof between her legs and rocking back and forth as she watched her little sister and her dragon boyfriend get it on like a stallion and mare in heat. Oh, Sweetie reminded Rarity so much of herself in her college days...

"Yes!" Spike gasped, breathless. "Yes. It feels really... really good."

"Now, since the two of you are pony and dragon, and of course so young, I don't believe we have much to worry about at this point. So, whenever the two of you are ready..."

"I'm gonna cum again," Sweetie whispered, locking her hind-legs around Spike's back. "Ohh, Spike, please don't stop..."

"Rarity?" Spike asked, his voice urgent. "I feel like I'm gonna shoot my stuff again. Is it okay if..."

"Don't ask me, dear. Ask the cute little thing you're fucking right now." Rarity smirked and rubbed herself as Spike looked back to his partner.

"Um... Sweetie... I feel like I'm gonna shoot again. Is it okay if I do it in your--"

"YES! Please, I want it there, I want it in my cunny, I want it, I want it, Spike, please, I'm gonna cum so hard... I'm gonna, oh, I'm..."

Spike didn't know what was happening, but he kept thrusting, burying his cock into Sweetie over and over as she began to shake. She wrapped her forelegs around him too and just seemed to clench, moaning and biting his neck and whispering things into his ear he couldn't hear or understand because he was cumming too.

"Sweetie--"

He just managed her name before his cock began to spurt again, this time firing load after creamy white hot load into Sweetie's little pussy. He rocked his hips back and forth, inhaled the air heavy with hormones, grabbed at Sweetie's fur and held on with his claws, closed his eyes and pumped the last few drops of cum into Sweetie's cunny. He didn't want to pull out, but his cock was so sensitive, he couldn't take the pressure and warmth and wetness anymore, and so he slid out of Sweetie's cunt with a 'plop', and a torrent of sticky white cum followed, pooling between Sweetie's legs and on the bed-sheets below. A little even managed to drip onto the bedroom floor.

The room was silent, but for the continual soft panting of pony and dragon trying to regain their stamina and composure. Rarity let out a contended sigh, and withdrew her hoof from between her legs, now also soaked.

"There. I think we can call that an altogether quite constructive lesson about love. I'll, uh, do the cleaning up, since it was I who instigated the lesson. And as long as the two of you remember what you were taught today, I see no reason you shouldn't be allowed to run off back to... wherever or whatever it is you'd like to get up to doing, I suppose."

Spike and Sweetie shared a grin. Spike's cock was hard again, bouncing up between his legs like a flagpole. Sweetie's cunny was soaked, from Spike's cum and her own arousal, and she clenched her legs together to feel the mix of jizz and girljuice.

"Yarn room?" Sweetie asked.

Spike nodded. "Yarn room."
