When Spike closed the bathroom mirror, he had an opportunity to get a good look at himself. Well, better than usual. A castle made from smooth crystal offered a perhaps not-exactly surprising amount of reflective surfaces.

The drake turned his head this way and that. No blemishes? Good! Scales all shiny? Splendid! His spines were straight, he had no bags under his eyes courtesy of a good night’s sleep, and his teeth were sparkly clean. The Spike in the mirror made finger-guns and flashed a bright grin.

“Looking good, Spike! Looking real good!”

He held the pose until the loooong sigh welling up in his throat just couldn’t be held back anymore. Spike slumped. His own face stared back at him. The grin had grown more wry than anything.

“Okay. Got that out of your system, beanstalk? Right? Right.” He nodded. So did Other Spike.

Spike turned away from the mirror and made his way down to the main library. Maybe Twilight needed some help to set things up for the… lecture. As he descended the stairs, he thought about what a strange situation this was. He’d never imagined getting advice about relationships from Twilight Sparkle. But then, who else could he have asked? Fluttershy? Rainbow Dash? Rarity? Spike rolled his eyes at himself. Now that was a recipe for disaster.

He’d reached the door to the library when he heard two voices speak. Somewhat surprised, he stopped just short of gripping the handle. He hadn’t heard anypony come in before. Was it Sweetie Belle? Was she already here? He leaned towards the door. The sound was muffled, but he could still hear well enough.

“... even said I could stay overnight if I want to, and you allow it, but I don't want to impose on you...”

“Oh no, that’s alright, Sweetie Belle! We have more than enough bedrooms if you change your mind!”

Spike took a calming breath. He wasn’t normally this nervous around her. So why was this different? Oh right. The lecture.Rolling his eyes at himself, he swung the door open. It revealed Sweetie Belle sitting on a couch, perhaps even one her sister had left with them if Spike remembered correctly. She wasn't a kitten this time; this was a more casual outfit, fitting a schoolfilly from a relatively well-to-do family.Twilight Sparkle stood before her; she’d done her mane up in a bun and wore a pair of low-sitting glasses. Blue blouse and dark purple skirt, she was affecting the librarian look more than ever for the occasion.

The Alicorn didn’t even notice him at first. She was happily chatting away with Sweetie Belle, all bright smiles and nods, but the filly, she noticed him. Right away she noticed him, as if she’d been waiting for him. Her head turned to look at him. Emerald eyes shone up at the sight of him. “Hello, Spike!”

He smiled back. “Hey, Sweetie Belle. Didn’t know you’d arrived a little early. How come nopony told me, huh? What the hay?” he asked in faux outrage. Sweetie tittered and swung her legs, while Twilight seemed to realise his presence just then. And even if he was joking—mostly—she had the decency to look a little abashed.

“Oh, sorry, Spike. You were still busy up there. I didn’t want to disturb you.”

“I’ve not been here long,” Sweetie Belle helpfully added. “Were you showering?”

“Um. Yeah?”

She looked pleased with his answer. She was smirking and looking at him with sparkles in her eyes, like he just made her day. Okay, then. He shook off the weird feeling he had best as he could and glanced over to their local princess. “So. How are we going to do this, Twilight? Are we going to eat first, then do… the thing?”

Twilight raised a finger. He could see she was already sliding into lecturing mode. “Don’t be foolish! We didn’t prepare anything yet. To eat, that is. So I think I will do my presentation first, and after that, we’ll decide what to eat if we're still hungry!”

Spike raised a brow. “And what if we lose our appetites first?”

That got him an annoyed look. “My presentations aren’t that boring!” With her hoof tapping the ground and her fists on her hips, she looked like a mare half her age. Spike had to remind himself that, for all her genius, being a hero, a princess, and having looked after him literally since birth… she wasn’t that much older than he was. He held up his palms to defuse her anger, giving her an easy smile.

“Not what I meant, Twilight. It’s more, the, uh, subject matter.” Spike rotated his hand vaguely in her direction. “Going into detail. With the specifics. You know?” He fervently hoped she would understand. In any case, his helpless look must’ve shown on his face since Twilight took a deep breath and visibly relaxed.

“I’m sorry, Spike. I didn’t mean to snap. Please be assured I did my best to make everything not… icky. Now then. Would you take a seat? Next to Sweetie Belle.”

Twilight pointed at the empty space next to the Unicorn filly, who’d helpfully scooted over to one corner and was patting the couch. Spike, equal parts dreading what was to come and wanting it to be over quickly, sighed, walked over to his designed seat, and plopped down. The sudden weight let Sweetie Belle bounce and left her leaned against him, but after her initial surprise, she didn’t seem to mind anymore. She seemed quite comfortable cuddling into his shoulder. Spike himself had the faintest blush and gently rubbed her arm.

Their mutual teacher probably hadn’t seen that, since she had her eyes closed. Twilight breathed deeply in, and out, physically pushing her anxiety away just as Cadance had taught her. Spike saw her wings open just a little, flapping awkwardly before going back to rest against her back. It was, frankly, adorable, not that he would ever openly tell her that. Apparently ready now, the Alicorn opened her eyes again, tugged on her glasses, locked them both with her gaze, and cleared her throat. A thick stack of flashcards took flight next to her head. Oh boy.

“Ahem! Welcome, students, to my first lecture on the many iterations of physical expression of romantic attraction in young adults, Or MIPERAY.” She paused, coughed into her fist. “It’s a working title. Moving on. My hope is, after we are done, everypony will walk away having learned something; a little wiser, a little more knowledgeable, and a little more prepared for the challenges ahead in this exciting new chapter in life.”

Twilight’s horn flashed purple with her magic. Behind her, a bright screen of magic unfolded in the air, free-floating, images formed from her power, easily the length of the entire library wall. Spike’s lips tugged with a proud smile. Number seventy-two, huh, Twilight?

The images soon began to flicker and then move. First morphing into a heart that soon split into two hearts, each of which was throbbing like it was alive and beating.

“When two ponies—or other creatures—experience a romantic attraction towards one another, they might then engage in actions meant to show said attraction. This can be gestures from one party, like flowers, cookies, or little gifts.”

As Twilight droned on, the images again changed to match her words: two hearts became two pony heads. Their eyes met, and smiles grew on their stylised faces. One presented a wrapped package, the other took it while the first looked away shyly.

“It can also take another form: in expressions of physical affection. Anypony who ever had a pet will know how enjoyable it is to hug and pet them. Something similar could happen with a romantic partner, but with additional options. Such as… kissing.”

The two pony heads, now longingly gazing at each other, suddenly closed their eyes, puckered their lips and moved towards one another. The mistress of the illusion, for her part, had grown red under her purple coat. Her face was flushed around her nose and cheeks. She was also squinting hard at the next card in her list. Then flipped to the back to squint at the next. And then one after that. Her blush only got worse with each moment.

Spike felt a poking sensation in his shoulder, pulling his attention away from the spectacle of the increasingly flustered Alicorn. When he looked to the side, Sweetie Belle was facing him. Her finger still pushed against his scales, but she turned her hand around to point at Twilight next. Sweetie Belle’s lips barely moved as she whispered to him.

“Do you think she got stuck on something?”

Spike shrugged. They both looked back to the princess when she audibly cleared her throat. Still red in the face, Twilight inhaled and exhaled. “I’m sorry about the delay there. I… I think I forgot where I was for a moment there. Or maybe the cards aren’t in the right order. Either way, we should continue. Where was I again?” She snapped her fingers. “Right! Kissing! Now, when it comes to kissing—”

“Have you ever kissed somepony?”

Twilight froze like a rabbit stared down by a snake. Her entire form turned rigid, as if struck by shock. Her illusion winked out at the same time, taking the two glowing pony heads with it. She wasn’t the only one who hadn’t expected the question; Spike was surprised as well. His head whipped about to look at the filly next to him, but she just sat there, peering ahead eagerly and curious. When she noticed his staring, she shrugged her shoulders. “What? It’s a legit question. Twilight is older than us. And she lived in Canterlot.”

“What does that have to do with anything?” Spike asked. Sweetie Belle shrugged again, though she avoided his eyes when she next answered. The filly fiddled with her fingers, shyly looking about the room. Perhaps she’d noticed the growing red on Twilight Sparkle’s features.

“Um. Well, you see, I found some books in Rarity’s house. Picture books. A bit like comics, but not quite. You read them from right to left. Rarity said they belonged to Fluttershy.” Sweetie Belle turned a little quieter. “They take place in Celestia’s magic school. There’s two students, who start out as rivals, really wanting to impress Celestia, but then they find out they actually like each other a little, and they start helping each other. And one evening, they both have dates, so they start practicing kissing. With each other.”

Sweetie Belle gave him a sidelong glance. Spike blinked as he tried to process what he’d just heard. Out of the corner of his own eyes, he could make out Twilight opening and closing her mouth, with no word coming out. She seemed to have trouble making sense of things herself.

“I… don’t remember anypony practicing kissing when Twilight and me stayed at Celestia’s school,” he said slowly. “I really doubt Twilight saw anypony do that either. I think she would’ve told me. At least later. So, in this comic, did he make the first move, or did she?”

“They were both colts.”

Spike blinked again. “Oh. Well, then. You found them at Rarity’s house?”

“She did say they were Fluttershy’s.”

Spike couldn’t help the awkward chuckle coming from him. He scratched at the back of his neck and shrugged. “Well… I’m not judging. You said Rarity said they were Fluttershy’s?” When the filly nodded, Spike ventured into even more unsure waters. “So, did you… like them?”

For a moment, Sweetie seemed to think. She rolled her eyes up and furrowed her brow, but even that, Spike noticed, made her look kind of cute. He also noticed Twilight had stopped zoning out and seemed to be waiting for the answer just as he was. Sweetie Belle, for her part, just sat there, kicked her leg, and thought intently. And then, she shook her head.

“No. Or… yes. Not quite. It’s complicated?” She turned back to Spike. “I liked them for the art. They were well-drawn, very smooth, not like in your comics. I liked the characters too. It was fun. But I think, colts kissing colts, that just doesn’t work for me. Whenever I read those parts, I kept forgetting they’re both supposed to be colts. I just kinda imagined one of them as a filly.”

Spike felt a soft, white-furred hand lay down on top of his. It was warm.

“You don’t think this makes me a bad pony… do you?” Spike looked up into two worried green eyes. Sweetie Belle held his gaze for a moment, before they closed and she sighed from deep within her chest. “It makes me sound like a bigot. But I don’t have anything against it. It’s—it’s just, whenever I think of ponies kissing, it’s a colt and filly.”

Spike pulled his hand from down underneath Sweetie Belle’s. He interlocked his fingers with hers, holding them together. She dared look at him again, now that he hadn’t rejected her, he figured. And her small smile made his heart beat loudly.

“What about, a dragon and a filly?” he asked her. She giggled, reached out with her free hand to touch his cheek. Spike grasped it as he cuddled his cheek into her palm.

“I might have thought of that too, yeah.”

Spike’s mouth split into a grin. “What about… two fillies?”

Sweetie Belle giggled again, ending in a cute little snort this time and there was a bit of a blush showing through her fur. “Before I say anything about that one, I think it’s my turn to ask a question again! So right back at you: have you ever thought of two fillies kissing? Or two mares?”

“Well…” Spike licked his lips. He wasn’t quite sure how to answer that one, but when Sweetie gently stroked his cheek, he calmed back down. There was something so soothing in her touch, and the way she looked into his eyes. Open, curious, accepting, a little bit eager maybe. At that moment, Spike almost felt like it didn’t actually matter what he said—as long as he was the one saying it. The grin on his face went wider as he chose his reply.

“I’ve thought about that, yeah. Most guys do, I don’t know any who haven’t. Who wouldn’t enjoy the sight of two girls kissing?” He nodded as he thought, nodded right into her palm. Sweetie Belle kept hanging onto his every word. “But I think it’s also because they like to imagine themselves somewhere into the picture. Like, ‘two girls are kissing right in front of me, maybe they’re kissing because I like to see them do it. Maybe they’re putting on a show just for me.’ You know, that kind of thing. I don’t know if other guys do it consciously or if it just happens. Probably depends on the guy in question. I bet you get a different answer from Big MacIntosh than from Pipsqueak, for example.”

“But you think they all thought about it at one point or another?” Sweetie Belle pressed. Spike nodded again.

“I’m fairly sure. And there’s more of you than us, so…”

“I’m fairly sure,” Twilight suddenly cut in, “my brother never thought about two mares kissing, or any mare but Cadance for that matter! In fact, I would bet on it!” The Alicorn had crossed her arms in a pout. While she’d found her voice again, she was still blushing brightly, for all that she was obviously trying to project certainty.

Spike immediately remembered several adventures Shining Armor had personally written for his Ogres&Oubliettes games featuring twin princesses from a mystical deer kingdom, who, upon being reunited, greeted each other with a rather lengthy kiss on the mouth. In front of the heroes. He’d stashed them away in the ‘too mature for Spike’ pile. Which, naturally, hadn’t stopped Spike from taking a peek as soon as he had a chance when Shining Armor was gone for guard recruit training. “Not sure you would win that bet, Twilight.”

Twilight glowered at him, opened her mouth for what was sure to be an angry retort. She stopped herself, however. Her annoyance gave way to something much less sure. The Alicorn put a hand to her chin and frowned, looking thoughtful. “You’re sure about that, Spike?”

“I’m sure about it.”

She looked down. Then up again. “Most guys..?”

“Positive.”

She looked down again.

Twilight was still silently contemplating his answer when Sweetie Belle suddenly pushed herself off of the couch and away from Spike. To his surprise. He found he missed her soft touch almost instantly. “Sweetie Belle..?” he asked.

She simply smiled brightly at him. Then she pivoted on her hooves, facing the Alicorn, with her smile now gone sassy and her hands clasped behind her back.

“I think we should try it, Twilight!”

The princess took a half-step back and one of her ears started twitching uncontrollably. “Wait, what?! How is it suddenly about you and me?”

“We’re the only two girls here.” Sweetie Belle shrugged, following the mare with a half-step of her own. “And you don’t have to think about it in terms of us-us if it makes it easier. This is to prove if Spike enjoys seeing two girls kiss where he can see it. That’s all.”

Spike bit his lip. He wasn’t at all sure that one of the two girls in question being the closest he had to either a mother figure or a big sister wouldn’t make it super-weird. He was still awfully curious, though. His gaze flickered between the two, the optimistic filly and the cautious Alicorn. Until the latter relented.

“Okay. Okay. Makes sense. Just for… data. That’s all.” Twilight was mumbling her words now. She met Sweetie Belle’s eager expression with one a little more hesitant. “So, am I supposed to begin the process, or..?”

Sweetie Belle turned out to be the one to start. And start she did. The filly took hold of the older mare’s head and head and brought herself in for the kiss; head tilted to the side, eyes just a little closed, lips opening shortly before contact. Twilight’s breath hitched, she seemed frozen again. There was no resistance to the lips coming together. Two Spike’s ears, that first kiss sounded… a little wet, a little smacking, more messy than he would’ve thought it would—and very, very hot, too. Sweetie Belle had to stand on tip-hooves to even reach the slightly taller than average Twilight’s face, but she made her very best effort. Spike saw two sets of red lips move against one another while their respective owners breathed through their noses, and after a long time that was probably not all that long, they parted again. Both of them had a glisten of wetness left on their lips.

Twilight stared at the forward filly. Wide-eyed, not quite wide-mouthed. Whatever blush she’d had on her before exploded into a crimson red to the point that the Alicorn looked drunk.Her arms hung limp at her sides. “Wha…” she finally got out.

“Hm.” Sweetie Belle pondered for a moment. “That was fun!” With a bell-like giggle, she glanced over her shoulder. “Was it fun for you too, Spike?

“Yeah. That was fun.” Spike’s mouth was a little dry. And his pants were a little tight. “Are you sure this is the first time you kissed another girl?”

Sweetie Belle winked and hummed. “First time I kissed a princess, that’s for sure! Want us to kiss again? Or do something else?”

Spike’s hand snaked down in between his legs. He just needed to... rearrange things. He nodded, slowly. “Yeah. That would be nice.”

“Wait—Sweetie Belle, wait,” Twilight interjected. She gently pushed the smaller mare away, who reacted with a disappointed look on her face. “Wait. Let’s slow down for a moment. A big part of relationships is not rushing things. And what did you mean with ‘something else’ anyway?”

“Well.” Sweetie Belle’s arms raised up to grasp the Alicorn once more, who pushed them away with a soft application of magic. The filly pouted for a moment, but quickly caught herself and brightened up again. “Well, I figured you had more things prepared to show us. That was always the plan, wasn’t it? Showing us kissing, among other things? You showed us kissing just now, and worked out. You’re a good teacher.”

Twilight did allow herself a pleased smile at the open praise. “Thank you, Sweetie Belle.”

Sweetie nodded. “So now, we’re ready for the other stuff. And we’re not rushing into anything either.” She pointed at Spike, who had himself almost forgotten he was even in the room by now. “Spike said he wants us to do more. So it’s okay. You probably had more material prepared than just about kissing, am I right?”

Twilight Sparkle stood there. The muscles in her face moved, but she wasn’t putting on any definite expression or saying anything. To Spike, it seemed like one of those moments where Twilight had an internal debate with herself. And since she was an excellent debater, it was a tough struggle. “I… I did have some other material prepared, just on the off-chance. I wasn’t actually planning on going this far today with the both of you.”

“It’s not that far.” Sweetie Belle shook her head, smiling her spotless whites. “It’s not far at all. Spike said it’s okay. He wants us to do more. For you to show us more. You can show us, with me, for him, because Spike said he would like to see.”

Twilight exhaled through her nose, but then gave a wry smile. “I guess you’re right. If Spike said he wants us to do more, it’s okay. And it’s not all that more out there anyway. We’ve already kissed, the rest is almost natural.” Her smile grew, and she patted the younger mare on her shoulder. “Good talk, Sweetie Bell!”

“I learned from the best,” Sweetie answered with a quick laugh. Twilight laughed too, and Spike couldn’t help but chuckle himself.

“Now, where had I been before our… kissing session?” Twilight crossed her arms and tapped her fingers in a quick rhythm while she thought. It didn’t take long before a metaphorical lightbulb lit up above her head and she brightened. “Right! I’d just been talking about physical gestures of affection in general!”

“Seems as good as any spot to start from again now,” Spike agreed, nodding to the princess. “So, what else is there?”

Twilight cleared her throat, stood up straight. She was falling back into lecture mode. Good, that means she’s feeling less awkward, Spike thought. He leaned forward in his seat, Sweetie Belle joining him on the couch again. She wrapped her fingers around his hand, and he gave her a smile in turn,

“There are other forms of physical affection creatures use to express attraction towards one another. Hand-holding would be one, for example.”

Sweetie Belle and Spike shared a giggle. “I think we have that covered,” she said, while raising their clasped hands in the air.

“Looks like you do!” Twilight flashed them a grin. She lashed her tail and went on. “That usually comes before the kissing, I should say. Holding hands in public is often seen as an especially romantic expression of affection. Aside from those, there are hugs, cuddles, nuzzles, going arm in arm…” She was counting things on her fingers now. Spike did not doubt for a second she’d noted ‘count on fingers’ on one of her flashcards. “And, of course, feeling each other up, posing for your partner, sexual stimulation, and actual intercourse.”

As Spike listened on, he imagined himself engaging in some of these things with somepony. Naturally, Sweetie Belle popped up as the default partner, all creamy white fur and bright smile and emerald eyes and eagerly leaning into every of his touches. Whether it was her shoulder, or her hand, or her arm, or her ass. He’d already touched all of those, hadn’t he? They’d already done that. He stared at their mutual teacher, slowly asking: “What about… giving her a spanking?”

Beside him, Sweetie Belle giggled and slapped his shoulder. “You didn’t do that, silly! That was only a few slaps on my butt at most. It didn’t even hurt all that much!”

“You, er, slapped Sweetie Belle’s butt?” Twilight looked between them. When the both of them nodded, she paused, and then cocked her head slightly. “I… guess that falls under sexual stimulation.”

Sweetie Belle nodded even more enthusiastically. “Oh yes! It was very stimulating! It made me feel all warm inside. And on my butt, too. On the spot he slapped me.”

“That is to be expected,” Twilight answered, with a hint of sarcasm creeping into her tone.

“So did that ever happen to you, Twilight?”

“No. I was a model student and exceptionally well-behaved as a child. There simply never was a need to use it as a form of punishment. As for pure physical stimulation, as of yet, I have not yet found the right pony to exchange such showings of affection.” Twilight sniffed once and went on. Because Spike was paying close attention, he managed to see her right hoof draw tiny slow circles along the ground.

Sweetie made a ‘hmm’ sound, “But, you would like to find one, yes?” she pressed. It made Twilight slap a hand over her eyes with a pained sigh.

“I get enough of those talks from mom. Or Cadance. Can we please focus on the actual topic again?”

“Sorry.” Sweetie lowered her head as she was chastened. There still was a tiny wag of her tail Spike could see. “I should've asked if you wanted somepony to slap your butt.”

“Yes, you should have.” Twilight raised a finger again for another mini-lecture. “There is an important distinction to be made between it happening because you did something bad, because you want somepony to provide you with pleasurable physical stimulation, and you want somepony to do it to you because you’ve been bad and it feels good.”

Sweetie and Spike both blinked. “So,” the former began, “does that mean you want somepony to slap your b—”

“There are different ways to physically stimulate a partner,” Twilight interrupted, “aside from touches, implements can also be used. Up to and including ones you would normally only use on yourself, shared use can create a valuable bonding experience.”

“For example?” Spike asked. He was growing curious where this was going. For all of Twilight’s neurotic tendencies, she wasn’t actually a bad teacher, he thought.

“Well, There are… hm.” Twilight glanced at a cardboard box Spike hadn’t really noticed himself. He didn’t remember how it got there; Twilight probably put it there while he’d been busy getting ready upstairs. The library was more her domain anyway.

Well, the entire Ponyville Castle was, legally, her domain, but they had a certain understanding. Some parts of it, he was more likely to be working and vice-versa. Like the kitchen—Twilight’s cooking wasn’t bad, definitely not anymore, but there was still a long way to go before it was anywhere the quality of his own. And the library was basically her second bedroom.

Now this new, unknown box floated towards the Alicorn, who pushed the lid open and took out the first new study object. Or rather, objects. Two eggs… no, wait. Eggs didn’t come in pink, or had cords attached. Plastic shaped like eggs. Twilight let one dangle in her magic on each of her sides and gestured to them as she explained.

“These are vibrators—specifically, bullet vibrators. According to Globetrotter, named so after the sling bullet used in ancient pony history, from before the Tribal Unification. Globetrotter believes there is a more direct connection as well; she argues the smooth, oval shape might have made for a tempting personal massage tool for lonely soldier mares on extended tours of duty, when nothing else was avai—”

“Oooh!”

Sweetie Belle’s wide-eyed interruption came exactly at the right moment for Spike, who’d feared a rather lengthy digression was to follow that initial mention of Globetrotter. Spike blinked to himself and wondered who this Globetrotter even was. His attention was soon drawn back to the two ponies with him, however.

The filly brushed her fingertips over one of the levitated toys. “How do they work? Do you put them in? Then what happens? Are they magic?”

Twilight smiled, pushed her glasses back into position—for dramatic effect, Spike decided, they hadn’t moved one bit even when she and Sweetie Belle had been smooshing faces together. “They vibrate! Thus providing the user with bodily stimulation that, I have read, is quite enjoyable. As to your other questions, yes, you put them in, yes, they are powered by magic—my own, in fact, that should keep them fully charged for several months at a time—and they are activated via remote.”

With a quick flourish, Twilight levitated a small pink plastic device from her Box of Mysteries. It was sized in a way that would likely sit in an adult hand quite comfortably, with two sliders and two buttons.

“This is the remote,” Twilight explained the obvious. The little item bobbed and rotated in her magic field, though it wasn’t all that interesting in and of itself. “The button switches it on and off, the slider controls the intensity. See the markers? That goes gentle to hard. One button and one slider for each vibrator. The little numbers on each side tell you which is for which.”

Twilight’s magic sent them both floating towards Sweetie Belle, who plucked them from the air with all the energy of an eager foal. After a short time inspecting both, she handed one back to Twilight, who seemed a little confused at the action at first.

“Here,” Sweetie Belle said. “Good thing you’d picked up two of them, that’s one for each of us. Now we can show them off for Spike! He’s the only guy in the room, after all.”

Twilight nodded, first haltingly. “R-right.” Then she nodded again, her confidence coming back in full. “Right! I need to show you how to put it in anyway, Sweetie Belle! Give me a moment. I need to get changed for this…”

Twilight was already halfway turned around on her hooves when she suddenly stopped. She cocked her head, one ear moving this way and that. And she shook her head, sought out Sweetie Belle’s gaze, put a hand on her hips. Twilight’s wings made a quick little flutter-flap and then rested on her back again. “Right. What was I thinking? I can’t very well show you how to operate them properly when I’ve left the room, now can I? Well, I guess I could, but it wouldn’t be quite as educational.”

“Educational is good,” Sweetie Belle sagely agreed. Her nods sent her curls bobbing wildly. “That’s what Miss Cheerilee says too! A good educational foundation is key to prepare us for our personal future prospects!”

Spike imagined the still fairly young herself, proverbially cheerful Cheerilee giving her classroom a lecture on the field. And he wondered. “Was ‘vibrators 101’ part of that lesson plan?”

Sweetie Belle seemed to think on that. She had a finger pressed on her cheek while Spike and Twilight both waited. “Hmm. I can’t remember it ever was. Perhaps it should’ve been, though?”

“I can talk to Cheerilee about it. Let’s first make do with everything we have here, alright?” Twilight put a hand on Sweetie Belle’s shoulder with a smile the filly reciprocated just as much. They nodded to one another in obvious, unspoken agreement, and then began stripping off their clothes.

Sweetie tittered as she pulled on her shirt, trying to get it over her head, getting stuck on her horn, pulling more and bending at the hip and in the process giving Spike a neat little show. After finally getting free of her shirt, she fumbled with her skirt next, still laughing quietly and having the time of her life, from the looks of it. She was down to her panties soon after, some outrageously red number Spike hadn’t seen before on her or anypony else that sharply stood out against her coat. She hadn’t worn any top with it. Sweetie Belle’s nipples were stiff at attention.

Twilight had tried peeling off her student uniform unsuccessfully so far. She’d managed to squeeze herself inside, but getting out again was even more difficult and not helped by both the Alicorn’s sometimes lack of coordination and her probable unwillingness to damage her old stuff from Celestia’s school. After a few attempts, and a quick look to the side to see Sweetie Belle already mostly nude, Twilight grunted and fired up her horn; the result being most of her clothes disappearing in a flash of magic. She was left in her underwear, a slightly darker shade of purple—from a ways away, she probably looked like she was wearing nothing.

Spike was breathing more deeply than before.

“Should we get these off too?” Sweetie Belle asked, tugging at her panties. Her shiny, crimson panties. Twilight shook her head to this and pointed down at her own crotch.

“No, let’s leave them on. It’ll help keep the bullet vibes in. I don’t want them to fall out and we step on them or something.” She held the little toy close to her eye, peered at it with her brow furrowed. “I wonder what way would work to keep it in place. Maybe some strap to tie it to the leg..?”

Sweetie nodded along thoughtfully, running her fingers over the smooth surface of her vibrator. “You’re right! Let’s stick them in, see how they feel!”

“Okay.”

Both mare and filly, without a further word, tugged on their panties to push the bullet vibes in. Spike had a pretty good glimpse of both of their pussies. His first at all, he realised. He saw they were both weirdly smooth and very inviting, and glistening just a bit in eager anticipation. Thin twin sets of fingers worked the oval shapes in between those pussy lips; Twilight had her tongue in between her teeth in pure concentration while Sweetie moaned quietly as she pushed the toy in. And when they were both done, they pulled their panties back up, tight and snug and showing just the outline of the cord through the fabric.

Just as they were sharing toys, they shared a look, and a giggle. And a blush, of course. Both of them were flushed in the cheeks. “Well, that doesn’t feel so bad,” Twilight said. “Not too full. Fairly comfortable. Not the most practical solution with the cord, but we could work on that.”

Sweetie Belle drew a finger along the cord’s outline, barely visible as a thin bulge. “Yeah. It feels nice. Now we give the remote to Spike?”

“Right! Here you go, Spike!”

Spike, who’d himself half forgotten he was even in the room, jolted awake from his stupor. Little Spike sat up straight as well. He was straining against his pants with quite some force, uncomfortably so, in fact. When the little plastic box plopped down into the palm of his hand, he could only stare at it dumbly.

Twilight nodded to him. “Go on. You’re the guy. Test it.”

Spike looked at the remote some more. Then he looked at the two ponies. The two pretty ponies, smiling their encouragement, but also looking a little flustered already. Waiting for him to play with the toys they’d just shoved up themselves. Play with them.

Like a switch had been flipped inside him too, he was overcome with the desire to do just that. To have a little fun with them. Why not, if they were asking? He pushed the button.

bzzzzzzzz~

The effect was immediate.

Twilight Sparkle stiffened, letting out a tiny “meep” sound. Sweetie Belle’s head moved back, exposing more of her neck, and she sighed from the pleasure. “Oooh, this… this is… nice…” she murmured.

Both were flushing even harder. Their breathing grew heavy. Spike couldn’t see the vibrators work, but he could see the effects they were having. Feeling mischievous, he turned the dial up on them; he was rewarded with increased fidgeting, even squirming, Twilight balling her fists and twisting her face into a grimace while Sweetie began moving her hip from side to side, swaying like a cat and her tail wagging slowly.

Spike gave them a harder push.

bzzzzzzzz~

“Oh Celestia!” The girls jumped, obviously surprised by the sudden intensity! Twilight bent forward, panting; Sweetie Belle pushed a hand to her mouth, even biting down on it to curb the short cry threatening to tear itself free. Spike saw the Alicorn reach low with trembling hands…

“Stop!” he ordered. Twilight’s head jerked up to look at him with even more surprise, and Sweetie too locked eyes with him. “Don’t touch those! Hands behind your backs!”

Both of them jumped to his command. Sweetie Belle had clasped her hands behind her back before he was even through ordering them, Twilight grabbed her elbows and hooked her wings over them next, most likely to help keep them in place. “S-Spike…” she said. He couldn’t place her tone. But he liked it. He wanted to reward it.

He turned the dial up, all the way. Full power.

BZZZZZZZZ~

Sweetie Belle moaned, quite loudly, her head lolling back with her mouth open and her eyes closed. She spread her legs, shaking legs, hips bucking now instead of the gentle sway from before, humping the air. “Stars, Spike! Spike! You, ah! Ah! Yes, please, oh yes~!”

Twilight fell to her knees. She smooshed her cheeks and her breasts against the floor, ass raised, tail stiffly flagged straight up. She seemed beyond words, overcome with pure physical sensation. Her whole body was trembling, at the mercy of the invisible vibe in her pussy.

The buzzing was so loud in Spike’s ears, he was sure there was no way the rest of Ponyville couldn’t hear it. It barely droned out the rush of his blood pumping. He held the remote like a magic wand, pointed at the girls, dialled to the hilt. He watched as he let them have it. His vision grew greyish; he’d begun to snort out a bit of smoke without realising. He got up from the couch when the pressure in his pants became too much. Not that it helped. And still he left the vibrators going full power.

With a groan and a strangled cry, respectively, Twilight and Sweetie Belle came. Their climax came fast, Spike switched the vibrators off right there as soon as he noticed. He was panting as well. The stiffness down there was nearly painful.

The three of them had to catch their breath after the experience.

“Well…” Twilight began. It was muffled. Her face was still pressing against the floor. “Well… well. That was…”

“Y-yeah…” Sweetie Belle agreed. She grinned, took a wavering step forward, then another one, and then fell forward like a sack of potatoes. Spike caught her just in time, and she smirked up at his face. She still had her hands behind her back. “It was… it was something. Something… fun.”

Spike didn’t know what to make of this. He stared into the pools of emerald peering back at him with a sense of affection he’d never seen anywhere else. Not directed at him, that is. Never at him. “Sweetie Belle…” he muttered.

He didn’t get any further. A pair of velvety-soft lips crashed into his, bringing with it warmth and a taste of strawberries. Sweetie Belle… was kissing him.

From the floor came a shaky laugh. “Looks like we can cross ‘kissing’ off the list of things to teach you.”

Spike felt it was only proper to accompany Sweetie Belle to the door after their lecture was officially over They'd settled for some daisy sandwiches, not much work for anypony involved and quickly devoured. There hadn’t been much else this evening; apparently, the vibrator practice had taken a lot out of the Alicorn, and she had declared a desire to go to bed early. They’d watched her stumble up the stairs like a drunk instead of teleporting, which gave the two of them another nice show of Ponyville’s local princess’s sparkly butt.

Now that Sweetie and he were at the castle entrance, Spike had a feeling of uncertainty. He didn't know if they were moving a little fast, or if put too much pressure on her. Thoughts like that weighed him down, and they flared up when Sweetie hugged him and he hugged her back, patting her bare shoulder. “I’m sorry, Sweetie Belle.”

“For what?” She drew back, still holding his hands. “You didn’t do anything wrong. Everything was fine. Better than fine!”

He bit his lip. Before he could answer, she touched his cheek. Soothing him.

“Spike,” she said, gently, “don’t think anything that happened today was bad. Especially not the lesson. Trust the lesson, isn’t that what you always say?”

He chuckled despite himself. “Yeah, I do.” She fell in with a giggle of her own.

“See? We wouldn’t have done this if we didn’t want to. All of us. That’s why you still have the remote.”

Spike felt for the little box in his pocket. She was right, he still had the remote. He hadn’t seen her take out the vibe yet. “You know, Sweetie Belle…”

“Yes, Spike?”

“We haven’t yet tested the range on these things. You think they could work from here to, let’s say, Carrousel Boutique?”

The filly’s eyes lit up. She booped his snout with an index finger. “Guess we’ll have to find out, hm? I can tell you tomorrow, if you like. A full report.”

“I’d like that,” Spike told her. And as they looked each other in the eye, he moved his face closer to hers. Closer… until their mouths were touching. It was an awkward kiss, lips on lips, no technique, no flourish, no tongue. It was the best thing he’d ever felt.

As he waved Sweetie Belle off—still only in her panties, she’d forgotten the rest of it in the castle, it seemed—Spike was overcome with another bout of curiosity. He pulled out the remote, and wondered. His finger hovered over one of the buttons. Spike decided to test it. There was a muffled yelp from upstairs.

“Guess Twilight didn’t take hers out yet either,” he mused to himself.

When Sweetie Belle arrived at her sister’s place, she made sure to enter quietly. She didn't want to disturb her if she happened to be 'in the zone'. She peeked into the living room, finding Rarity poring over a piece of paper with a quill levitating right beside her head. The mare looked up and brightened from the rather gloomy face she’d been pulling just before.

“Sweetie Belle! You’re back! How was it?” She looked her up and down, and the smile turned slightly saucy. “From the looks of things, I would say it went rather well?”

Sweetie Belle all but hopped in through the door. “It was sooo good” she gushed. “We had so much fun! And Spike KISSED me!”

Rarity’s mouth fell open in shock. Then her expression melted into pure joy. She rushed up to the filly to embrace her. “Oh, Sweetie Belle! That’s fantastic! I’m so happy for you! That’s everything you wanted and more!”

“It is.” Sweetie Belle nuzzled into her sister’s neck. “It really, really is. But… Rarity? I need your help now.”

“Of course! Whatever you need!”

Shortly afterwards, Sweetie Belle was lying on her bed. On her stomach, to be precise; her arms were tied behind her, with a rope going to her ankles which were pulled up in turn. She couldn’t move much like this. She certainly couldn’t touch herself down there.

Spike had told them not to touch the vibrators. He'd never rescinded that order. Now she couldn’t. Sweetie Belle smiled, pleased with herself. Would Spike actually test the remote now? Would it work out here? Would he switch it off again if it did? Would she have to spend the rest of the night squirming like a worm if he didn't, helpless to the pleasure, until Rarity came to release her in the morning?

Lying on her bed, surrounded by her favourite lewd books, Sweetie Belle could hardly wait to find out.

Author's Note

So. Made it before year's end.

I hope this won't disappoint too much. I had some struggles with this chapter, which probably shows. Great thanks to Pone Peddler 9 for helping me get out of the slump!

Merry Christmas to everyone, hope you had a wonderful fest!
