Tied Up in a Neat Little Bow - [Contains Futa]

Some days, when she was younger, Twilight had lain on her back in a field and tried to find the shapes in clouds. She’d bring a book, and pretend the shapes in the clouds were reading over her shoulder if she felt lonely.

Now she was trying to spot the shapes in the clouds from above. It added an interesting twist to the old game, that was for sure. They were so different from this side!

Replacing the book was an empty bottle of wine. And replacing the clouds over her shoulder was—

“That totally does not look like a cat,” Rainbow protested.

“A sleeping one,” Twilight amended, “See, it’s curled up in a ball, and that's its tail.”

Rainbow tilted her head a little, staring at it. “Still don’t... Oh! Oh, yeah, okay, I gotcha now. Okay, yeah, so those are its ears, right?”

“You see it now, right?” She smiled, a drunken smile that had nothing to do with the wine. Well, only a little to do with the wine.

This was so much nicer than when she was younger.

She squeaked as Rainbow nipped at the tips of her ears. “Ears are cute,” Dash agreed. “And I just remembered yours are pretty sensitive.”

“Lies.” Twilight sighed happily as Dash nibbled down the edge of her ear to where they met her jaw, planting fluttering little kisses before working her way back up to the tip, “Lies and slander.”

“Oh yeah?” Dash breathed, sending pleasant little shivers down Twilight’s spine, “You gonna sue me?”

Twilight practically purred as Dash worked her way around, trailing on the other side and leaving little nibbles down and towards the base of her neck. She swallowed back down a gasp, which would just be admitting defeat. “Maybe I will. I’m a Princess. I can do that.”

Dash traced a hoof up Twilight’s spine as she continued work on the ear. She melted into the cloud they were nestled on, the softness of the touch blending perfectly with the warmth from the wine. “You can?”

“Yeah.” Twilight nodded. “Lock you up,” she added for good measure, between ragged sighs. The hoof made slow, lazily circles between her shoulder blades, and she sighed happily. Little sparks shot through from the touch all the way down to the tips of her hooves.

“Maybe we should get the Princess home,” Dash suggested softly.

“No...” Twilight complained, melting further into the cloud. “So soon?”

Dash hesitated for just a moment. The hoof stopped, the nibbling paused while she seemed to think about her answer. It was just a second, maybe two, but it was there. “I didn’t say I was done with you, Princess,” she finally whispered, “I just said we should probably get you home. See who locks who up.”

Twilight’s ear flicked. So that wasn’t... she meant... Oh? Oh!

Oh.

The words were hard. She wanted to say yes, but she couldn’t admit to wanting it. To say it would be to make it real, and that was not something she was ready to do. Nodding her head, leaning back into Rainbow, that she could do.

She wanted it, but she wasn’t ready to admit it yet.

Dash nudged her. “What do you think? Spike’s with Applejack and the Crusaders tonight, isn’t he?” Another nip at Twilight’s ear, sharper, and she held the groan back. “So it’d just be us...?”

“Yeah,” she breathed, the groan rolling out in waves. “Just us.”

There was another pause, a little longer, while Rainbow seemed to wonder... something. Then a wingtip reached out and trailed down along Twilight’s spine just at the waist, from the small of her back to the tip of her tail and back again, even as she nipped at Twilight’s neck. “We don’t have to, you know. We could stay right here, where anybody could see us...”

The wingtip pressed harder into the base of Twilight’s tail, and she realized it wasn’t an empty threat. Worse, much more teasing, and she might start thinking it was a good idea.

Twilight ducked under and out of Rainbow’s reach, leading Rainbow’s head down. Her feint successful, she leaned back up and forward with a gentle kiss on the cheek, and felt the heat of the blush against her lips. Smiled again. “Alright then,” she whispered, “take me home.”

Dash kissed her once on the lips, firm and close-mouthed, before standing on their little private cloud together which had proven to be not-quite-private-enough. Rainbow’s tight, thin-lipped smile made her look like she was trying not to burst out into cheers and laughter, a victory dance. Twilight just felt the bouncing of her heart around her ribcage, the emptiness of her gut, and a very pressing reprioritization of blood flow to more sensitive areas.
This wouldn’t be their first time together. She wasn’t an innocent, blushing virgin. Well, not innocent, anyway. But that time was still a recent memory, and she still felt keenly self-aware as Dash led the way back to the library.

She wondered if anyone looking up at them would know what they were off to do... would they judge her? Or would they think about it with interest, like... and there went the fluttering, again.

It didn’t help that Dash was flying just ahead of her, just above her, letting her tail trail up. It wasn’t helping at all, but it probably wasn’t meant to be.

Twilight remembered she’d left the wine bottle back up there. Hadn’t thought to grab it. Now she was a litterbug. Did she go back? Did she ask to go back? But then they were at the library, and Dash was standing beside the door expectantly, rocking her weight back and forth against her back legs impatiently, and Twilight realized something very important;

Tonight, she didn’t want to be a good girl.

She unlocked the door, and Dash opened it for her, nothing but class. Made an ‘after you’ gesture with her hoof, swooping low into a mock bow. Twilight giggled, as much from nervousness and anticipation as at just how silly it was, and went through.

The door slammed shut behind her. Dash was against her, fast, before she even had time to turn around. In one quick move Dash had a wing wrapped around her other side and was holding her steady, pinning Twilight against her, and Twilight felt teeth press against her neck, starting low near the chest. Then Dash started suckling, pulling the soft flesh over the edges of her teeth and slid smoothly up, pulling the sharpness up towards Twilight’s jaw.

She shuddered.

“Hey, little Bookworm,” Dash breathed, her voice hoarse and dusky and deeper than it usually was, than it had any right to be, “You’ve been waiting all night for this, huh?”

“Mmhm,” Twilight groaned, then gasped sharply as Dash bit again, firmly, to the left of her throat, along the tendons. Dash was pulling down, little by little, leading Twilight with her, down towards the ground. Within moments she was almost pressed to the floor, her ass held high in the air, trembling slightly.

Dash’s wing trailed up along Twilight’s spine again, the top of her wing edge leaning against the bumps of her vertebrae, sending icy shudders along every rise and fall of pressure, and down towards her hips. Teased the outside of her upper thigh... then her lower thigh... Twilight groaned pitifully when it went down to her knees instead of inwards.

Rainbow kissed her on the cheek, as if to just rub it in. “You wanted something more, did you?”

Twilight nodded. Rainbow went for the throat again, the other side of her neck, holding her head steady.

“I asked a question, Bookworm.” Again, a voice far deeper than usual, that seemed to send Twilight’s conscious mind into a deep, dark corner of itself. “Use your words.”

“Yes.” Twilight breathed, couldn’t bring enough air into her chest to speak, just vaguely pant what she wanted. “Please.”

“Please?” Rainbow asked again, wingtip trailing higher, back up her thigh, back up to her hips, always staying around the edges, never moving deeper. Twilight almost whimpered. “Please what, Bookworm?”

“Please,” Twilight repeated, too far gone to feel embarrassment at the whine of her own voice, “More. Please.”

“More?” The wingtip trailed up and over, pressed hard little circles around the base of her tail, then down her thigh on the other side, down all the way to the back of her knee again. Twilight’s face was still pressed down towards the floor, Rainbow suckling on the the flesh where Twilight’s neck met her jaw hard enough to bruise, in just the right ways that Twilight couldn’t help but hold her breath and clench her jaw whenever Rainbow pulled deep. “More what?”

Twilight groaned. “Don’t make me say it.”

The wingtip went further out, and Dash stretched her other wing over, massaging Twilight’s cutie mark from both sides, pressing against the meat of her flanks, long teasing massages that made her burn that much hotter. “You gotta tell me what you want, Bookworm.”

“I want you. Please, Dash?” She was dripping, and clenching at nothing. Pressed into the ground as she was, her tight little butt thrust into the air how it was, she heard the drip of two small drops of her arousal hit the hardwood floor, thought about having to clean that up later, and she burned with a blush. It could have been from excitement or embarrassment, she was too deep down to know.

Dash eased off her neck, and wandered around Twilight, admiring the view. She didn’t change position, couldn’t bring herself to, just took the moment to breathe, to catch her breath, to adjust to... the everything, the wonderful everything.

Then Rainbow pulled her legs apart, hard, yanked then, and Twilight squeaked. She wasn’t going to get her chance to recover.

“Right here, Bookworm.”

“Yes.”

“Looks like you need it bad, huh?”

“Yes, Dash, please.” She whined, actually whined.

“Please what?” Dash crooned, kissing Twilight low on the thigh, close to her left knee, gentle fluttering kisses that did more to torture than to please. She tried to twist, to try to force Rainbow to where she was most needed, but Rainbow just held her down firm. Twilight felt like she could cry in frustration.

“Please will you...” Twilight stopped short, choking on a whimper. “I don’t want to say it.”

“Yeah?” Dash crooned again, low and easy, “Because I really want to hear it from you, Bookworm.”

Twilight shuddered again. “Please...”

Dash kept nibbling, holding Twilight’s legs spread and biting her inner thighs, only her cheeks ever brushing even for a moment against where Twilight really just wanted Dash to bury her muzzle and lick. “You don’t want to say it because only bad girls ask for it, right, Bookworm?” A long lick up her thigh, curving around to the base of her tail without once giving her a moment of real satisfaction.

Twilight nodded desperately into the floor, yes, yes, please. Dash swatted her high near the cutie mark, once, let the sharp pain ring true for a moment, and Twilight whimpered into the hard wooden floor.

“Don’t you want to be a bad girl for me tonight, Bookworm?”

“No...” Yes.

“Bad girls get satisfaction.” Dash reminded her with another short, sharp smack which rocked Twilight’s entire body. “You going to be a bad girl for me?”

Yes, please.

Another short, sharp smack and Twilight didn’t quite catch her weight, gasped, slid and stretched forward on the floor a little. Dash hesitated for a moment, a moment, but then the ragged, panting breathing started up again, and she knew she hadn’t gone too far, hadn’t gone far enough yet.

Twilight was going insane. Her hips bucked at nothingness, grabbed at air, twitched whenever Dash’s hot breath teased her without ever delivering. Rainbow walked around, leaned down to Twilight’s tortured face with its chin lying flush with the floor, picked it up with both hooves and kissed her hard, tugging her lower lip with her teeth and flicking the tip of her tongue against the soft inside edge, trailing firmer lines. Let go, let it snap back, let them both gasp.

“Just for me.” Rainbow whispered to her, with a much gentler kiss on her forehead, just underneath her horn, “You don’t have to be good for me. You’re all mine no matter what, Bookworm.”

Fuck.

Dash held Twilight’s face tight in her hooves, held her so they were eye to eye, stared into her, stared through her. “What was that?”

“F-fuck me.” Twilight’s voice trembled, as much as her legs, as much as her everything as Dash held her. “Please. Please, f-fuck me, Dash.” She paused, breathing hot and wet and heavy, “Please.”

Dash kissed Twilight hard, just pressing Twilight’s mouth open and sucking her tongue between her teeth, letting the soft underside scrape and press against Dash’s teeth as the tips of her wings wrapped around Twilight’s sides, pulled at the edges of her burning lips and spread them, let the sudden sharp burst of the cool library air draw a gasp that pulled her deeper into Rainbow’s hungry kiss.

The leading edges of her wings were rigid and springy, but soft and delicate. As she pulled lightly against Twilight, forcing her to feel that almost painful emptiness, she drew hard circles with the leading edges of her feathers, which didn’t ease the need so much as overwhelm it, a meaningless shout over a desperate, pleading whisper.

All it did was force the whisper to become louder to meet it.

Twilight’s horn began to glow. She needed more. The spell started forming in her mind as Rainbow bit down on her lip, shattering her concentration.

“Didn’t say you could use magic, Bookworm.”

F-fuck.

“But I need it.” Twilight whimpered again, her voice fracturing.

Rainbow kissed her on the forehead, just above her brow. “Aren’t I enough?”

“No!” Twilight protested, and Dash smiled wider, because she knew it. The wingtips pressed harder, and one trailed lower, lower until it was circling-

F-f-f-fuuck!

Circling just around Twilight’s clit, never quite touching, just a firm and even circle around the edge, never breaking pace. Even and electric. Twilight pressed her head down hard into the floor, her hips twitching wildly towards the ceiling, jaw clenching hard. Dash gave her a peck on the lips with a chuckle.

“You look so cute when I tease you, did you know that?”

“S-shutup.” Twilight gasped.

“I’m sorry,” Dash’s tone was all mocking now, all torturous teasing, “What was that?”

“S-s-shutup and f-fuck me.” Twilight stammered, the words not coming naturally to her but the desperation forcing them out of her. Besides, she didn’t need to be a good girl, not tonight.

The circling stopped for a despairing moment, and Twilight wanted to cry. The feather crossed back up, directly over the bundle of hot nerves and she bit her cheek to stop herself from screaming, and then it was circles again, harder and in the opposite direction.

“You don’t get to cum yet, Bookworm.” Rainbow warned her. “You’re way too cute like this. How about that?”

Twilight groaned in frustration. She tried to raise her head, but every time she did Rainbow would shift her weight, press a new bundle of nerves, lead her back up and over herself. Her back legs were trembling, her knees kept bending against her will, and she burned painfully for more.

But Dash kept bringing her so close, so close, then letting her fall back down away whenever she was about to cross the edge. Kept making her sigh, and groan, and whimper, and moan.

The tip Dash was using to spread her, tease her lips, wandered inwards slightly, trailed a deeper circuit, and then just as it was almost inside her, just as she could almost-

It drew outward again, Twilight mashed her face miserably into the floor, groaning and half-sobbing.

Then Dash chuckled at that, and a switch flipped in Twilight’s head.

Her horn glowed bright. Dash’s wings stopped, more out of surprise than anything. She whispered in Twilight’s ear; “I said you couldn’t use magic, Bookworm.”

“Yes,” Twilight said as she picked Dash up, held her beside her. Unfolded herself from the floor, felt her own juices leaking down her thighs from the heat of her dissatisfaction. “And I said fuck me.”

“Ah—”

“And you said I don’t have to be a good girl tonight,” she continued thoughtfully, making towards the stairs up, carrying Rainbow closely behind her. “You just said I was yours, didn’t you?”

“Well—” Dash gulped.

“So here’s what’s going to happen,” Twilight threatened in a sweet sing-song voice, “I’m going to do terrible, wonderful, awful things to you until you feel exactly as unsatisfied as I do right now,” She noticed Dash’s hoof was wet, she hadn’t seen her playing with herself, felt a huge spike of jealousy, “and then you’re going to fuck me so hard. Is that understood?”

Dash fidgeted, but she couldn’t move much in Twilight’s grip. Good. “Ah... would it help to say, I’m sorry?”

“Oh, Dash~” Twilight sighed happily, “Let’s teach you what sorry means first.”

She darn near tore the door off its hinges as she threw Dash back-first onto the bed, where she landed with a soft bounce. It was a lovely bed, and it was going to be a shame to ruin it so thoroughly.

Twilight thought back to the innocence of her childhood, her adventures with the filly scouts, camping with her brother... she didn’t care much for the outdoors, no, but she liked knots. Knots were pretty, and intricate, and clever. One kind of knot loosened when you pulled it just so, and tightened if you pulled against it. With enough rope, you could do some interesting things.

This was much better than when she was younger.

Rainbow’s wings were bound behind her back, first. That, more than anything, would make her feel exposed. Next, her forelegs up above her head and tied to the solid bed frame. That was just to build anticipation, let her feel trapped, as more rope looped around her chest, her waist, her thighs, complicated trusswork that spread the restraint around her body, stopped anything from being too tight.

She wasn’t going to let Rainbow end up hurting herself; That job was solely Twilight’s tonight.

Then her legs were each tied to a bedpost, and a rather ingenious loop of rope at the frame could, at a pull, spread her legs or let them close, depending on how merciful Twilight felt at any given moment. Now? Now she practically yanked it, Dash’s legs a near perfect V shape.

Twilight crawled up between them, resting on the bed, looking at Rainbow’s nervous eyes across the length of her body.

“Hello, lover.” She smiled.

“Ah... hey.” Rainbow grinned nervously. “Whatcha doin’ there?”

Twilight looked pointedly at Rainbow’s exposure for a moment, at her curves and folds and wetness. She truly was beautiful. “Oh? Absolutely nothing.”

“Heh... nothing?”

“Yes.” Twilight nodded, smiling. “Nothing.”

“O-oh.”

There was silence as Twilight continued to be very satisfied to do... absolutely nothing.

Dash squirmed. “Ah, is that... is that it?”

Twilight batted her eyelashes innocently. “Why? What do you mean?”

“You’re really just... just going to do nothing?”

She considered that for a while. “Yes.” She decided. “Nothing at all.”

Dash banged the back of her head against the pillow, eyes screwed shut in frustration. “But you’re right there.”

“Oh? And where’s that?”

“You know! Right... right there...”

Twilight smiled, letting a teasing edge enter her own voice. “Oh? And now who’s gotten all shy, lover girl?”

Dash squirmed, and groaned, trying to rub her thighs together, trying to loosen herself, but nothing really came of it. Twilight’s frustration still burned her like a hot coal, but now that she was in control she could be patient, have all the patience in the world.

“I’m sorry, okay? Could you please... help a girl out?”

“Oh, I’m not even that upset really,” Twilight continued in her teaching voice, “It was actually kind of fun, don’t you think? Here, maybe I’ll show you.”

Twilight leaned forward and took a long, deep lick of Dash’s labia, starting low and pressing around, tasting the salty-sourness of it and working her way up to Dash’s own clit, took all of it in her mouth and suckled on it slightly, swirled her tongue around it lightly and released.

Dash started off with a low, rolling groan, building up to a desperate moan that ended high up in the clouds in a surprised, lustful shriek, punctuated by a sharp gasp and ragged panting.

“See?” Twilight smiled, licking Dash off the edges of her mouth, savouring the flavour of it. “Wasn’t that fun?”

“Mmmmmmmmmm.” Dash rolled the sound deep in her throat, out through her nose, still trying to catch her breath.

Twilight rested her chin on Rainbow’s stomach, gazed lovingly into her eyes. As Dash caught her breath, she looked down at Twilight’s gaze and smiled back awkwardly, started squirming again.

“Ah, was that... it?”

“Yes. And wasn’t it fun?” Twilight smiled wider, eyes showing just the slightest hint of menace.

Dash’s head rolled back and she let out a three note sob, eyes winced shut in frustration, in desperation. Good.

Twilight’s horn glowed. There was the roll of a drawer opening, then shutting again. The next bit was going to be especially fun.

She crawled up over Rainbow until she was standing on top of her, over her, looking down into her eyes. Rainbow still hadn’t seen what it was, exactly, she’d pulled from the drawers... best to keep it that way for a moment.

Looked at Dash’s eyes, at her blush, at her nervousness. Kissed her once on the cheek. “Do you trust me, Rainbow?” she asked.

Dash pouted, and it was all Twilight could do not to giggle at it. “You’ve got me tied up to your bed, all exposed, torturing me... and you’re asking me if I trust you?”

“Yes.” Twilight nodded, and leaned in for another kiss. This time Rainbow’s tongue flicked out, not bravely like before but nervously, almost shyly. The kiss was delicate, but no less intense for it. Twilight leaned back, slightly breathless, Rainbow panting. “I’ve been trusting you to say ‘no’ up until now if you’d really been uncomfortable with anything, but now I need to ask.”

Rainbow screwed her eyes shut tight. “Nngh.”

“What was that? No?”

Rainbow shook her head, and Twilight’s heart sank. She didn’t... but no, she meant, ‘no, that wasn’t a no’. What then?

“Don’t make me say it...”

“Say what?”

“... I kind of...” Rainbow gulped nervously again, mouth dry in spite of everything, “I kind of really like this. This is really hot, okay?”

Twilight kissed her again, just gently on the lips, let her know she was loved and safe. “Yeah? So what happened to my big brave dominatrix back there?”

Rainbow pouted again. “H-hey! That’s... that’s fun too...”

“But?” Twilight started nibbling at Rainbow’s neck, at the same spots she’d learned to love so very recently, started listening for the best gasps, the best moans, the right pressure to put on the right spots. Made a catalogue of chords she could play with her new toy, so she could learn to play her like an instrument.

“I—ah! I dunno but...”

“You just like it when I take control, then, hrrm?” Twilight crooned, desperate to touch herself, or just let herself sit on Dash’s face and be done with it, but letting her patience shine through. “You want the struggle don’t you? You want to lose.” Dash gasped as Twilight nipped a spot on her neck that would absolutely bruise the next morning. “You like having control. You just want your Bookworm to take it all away from you, and leave you helpless... and exposed... and have nothing you can do about it, don’t you, little Rainbow?”

“Mmmmf.” Rainbow bit her lower lip, not saying anything, looking away from her. That wouldn’t do at all. Twilight leaned in and sucked Rainbow’s lower lip with her own, toyed with it, teased it, pressed her teeth against it and chewed it ever-so-lightly, anything just to stop Rainbow from being able to hide behind it.

“Isn’t it so much easier when your Bookworm is in control, little Rainbow?” Twilight crooned gently. “You don’t have to try, don’t have to think. Don’t have to worry, let me do the planning for you. I’m yours, Rainbow.” Twilight whispered in hot breaths, “But you’re all mine too. And right now, I want to experiment...”

“Okay.” Rainbow squeaked, blushing bright red, her wings twitching against her ropes like she was trying to cover her face with them. Twilight planted a kiss lightly on her chest, then another.

“No hiding, little Rainbow.” Twilight scolded, “Not from me. I see through you anyway, don’t I?”

Rainbow nodded miserably, but she looked tensed like a spring doing it, her whole body coiled in wait for... whatever came next. That’s what she was waiting for.

Twilight showed off the thick red candle, the book of matches and the letter opener. Dash’s eyes widened, but Twilight trailed down her chest with the tip of a hoof reassuringly, down to her stomach, back up, slow and relaxing trails, reminded Dash of where she was, reminded Dash of who she was with.

The apprehension melted seamlessly back into anticipation as Twilight nipped at the underside of her jaw a few times, murred happily.

“I thought the wax would match the colour of your fur,” she admitted, lighting the candle and leaving it on the bedside table, “and the knife isn’t that sharp... just sharp enough.”

“Enough?” Dash gulped, staring at the blade which was floating lower, lower, past her stomach, past her thighs, down to her ankles...

“Yes.” Twilight nodded. “Enough.”

“Enough for—”

The tip of the letter opener pricked Dash, sharp. It was barely a gasp, more a shocked inhale, but it cut her off neatly. Twilight smiled again.

The knife trailed up slowly, a little higher. It pricked again, never sharp enough to break skin, but trailed up Dash’s legs in alternating rhythm. With Twilight lying across her chest they way she was, she could never see where it was about to strike. Against her calves, against her knees, prick... prick... prick...

Then it got to her thighs, the inside of her thighs, and the anticipation had already made Dash so sensitive. The restriction, the ropes... she twitched against them, pulled without meaning to, tried to wrench her legs closed, but the most she could do was rock a little side to side. Still the knife continued upwards.

“Ah~!”

Still a foot away from... “Ahh~!” No, now eleven inches, on her other thigh. A little harder, a sharper gasp. Three little pricks in quick succession elicited a low whine, and going randomly—without a tempo and changing her pressure each time—caused Rainbow to thrash about, to clench her teeth shut and to groan constantly through them, to kick her forelegs up against the headboard and her hindlegs out and together, but Twilight continued closer, closer, three inches now and—

“EeAh~!” Rainbow’s groans were needy and needful, frontloaded with almost-squeaks.

Twilight switched tactics, going from the pricks to sliding the tip of the blade in circles, just like the feathered wing tips had before. The same pace, the same feeling of helplessness... the soft, feathered edges replaced by warming steel. Sharp enough that it was electric, but never breaking the skin.

She leaned forward against, held a fold of Rainbow against the flat of the knife, and kissed it with closed lips against the edge of the blade. The rush of blood was intense, and Twilight could taste the rush of blood with the tip of her tongue, as Rainbow bit back... something and thrashed her head back against the pillow again.

That wouldn’t do at all. Twilight moved the knife back, her head back, and looked at Dash seriously, stern with her teacher face on again. “You’re being very quiet, little Rainbow.” She chided. “Isn’t this enough for you?”

“S’nough,” Rainbow grunted, turning a three syllable phrase into a single slurred word.

“Then why don’t you scream for me, lover?” Twilight crooned, letting the tip of the knife press dangerously close to the hood of Rainbow’s tight, pink nub. “I’d really like that.”

Rainbow grunted again, eyes screwed as shut as she could make them, jerking her head back and hard to stare at the headboard, at the ceiling, anywhere but down at Twilight.

Very well then.

Twilight flicked the knife down slightly, using the tip to pull the hood up gently, let the sharp tip resting against it be pronounced without needing to add any further pressure. There was a risk of overstimulation.

She flicked her tongue out, the taste of Dash mingling with the static taste of the knife, and pressed down until Dash’s struggle to keep the noise down, keep quiet, was a dam close to overflow. She writhed and tossed herself against the ropes, tried bucking her hips up and into Twilight, she bit and swallowed gasps, choked down moans, but was otherwise quiet.

A pity.

Twilight knew forcing her over the edge would break the dam, and she’d get some damn satisfying noises for her efforts, but that time wasn’t now.

Now the candle had pooled a satisfying amount of wax, and it was time to have some fun with that.

The opener fell back. The candle held over Rainbow’s stomach, and just a little lower. Twilight gauged the distance by eye, found it good. Just about eye level, a bit more. That should be right.

“Now, you’ve got to help me here Rainbow.” Twilight nodded to herself, “If it’s too hot I need to pour from higher up. Too low and it’ll burn, alright? So you’ve been a very shy and quiet girl for me so far, little Rainbow, but I’ll need you to talk to me now.”

Rainbow didn’t say anything, just nodded, still not looking at her. Seemed conflicted on how she felt about Twilight stopping, with how close she’d obviously come. She’d won, and her prize was remaining unsatisfied... perfect.

The first drip, just below Rainbow’s ribs on the sensitive underbelly. The taut, athletic muscle had no almost no insulating fat, was that much more immediate and intense for it.. Rainbow hissed, pulling her forelegs hard against the restraints like she was reaching to cover herself, and Twilight hesitated.

“Higher, or stop?”

“Sssame,” Rainbow hissed, still kicking in small spurts as the wax settled and hardened. “Just wasn’t... expecting it.”

Twilight nodded again. Took the knife, slid it along the waxy edge and scraped the hardened drop off, leaving the now incredibly-sensitive skin underneath exposed, planted a kiss on it.

She repeated once more, drop, let Rainbow hiss and squirm, scrape off, kiss, just to the other side. Another time, drop and squirm and scrape and kiss.

“So that’s what it feels like to drip.” Twilight said, voice calm and even, just another lesson. “But we can pour as well. Are you ready for that?”

Dash paused, gulped. “Can you start a little higher...?”

Twilight nodded, the candle went up another inch, nearly two. She considered it, backed it down a little. Deemed the new height good.

Rainbow’s eyes weren’t screwed shut now, she was watching the candle in anticipation, her thighs trying to squeeze shut again, or maybe just trying to squeeze. Twilight tilted the candle and let it pour freely onto Rainbow’s stomach in a long straight line.

“AhH!” Dash exploded, pulling in every direction at once, wincing and slamming her forelegs into the mattress again and again, and again Twilight paused.

“Higher, or—”

“No!” Dash hissed, her breathing ragged and hoarse, “No, just... intense.”

“Yeah?”

“Y-yeah.” It wasn’t a stammer of nervousness or shyness, Dash had just shuddered happily as she said it. Twilight was satisfied.

“Good.” Again she flicked the knife, rolling the wax off in red flakes, letting it collect in Dash’s fur. It really was a beautiful colour on her. Shame it got in the way, or else she’d be tempted to keep it. “Because I’ve been sorely neglecting your teats, lover. So; Drip or pour?”

“M-my teats?” Dash squeaked. They’d always been especially sensitive, apparently way more than Twilight’s own which surprised her. But no, it turns out that Rainbow’s tight, athletic body was far more sensitive than the hard muscle would imply. But Rainbow was a far more sensitive girl than she let on in a lot of ways, wasn’t she?

“That wasn’t the question I asked you, little Rainbow.” Twilight flexed her voice like a whipcrack, and Rainbow’s eyes darted down, tight frown and blushing cheeks. More squirming. Twilight would have to remember how she spoke like that, it seemed. “I asked you drip or pour.”

“Are you still going to... do the scraping thing... and the kiss?” It was hard to read her voice. The trembles could have meant anything from anxiousness to excitement, and the tone could have been anything from hopefulness to trepidation of the inevitable. Twilight watched Dash’s face a moment, and realized Dash probably didn’t know herself.

Well, they’d find out together, wouldn’t they?

“Yes, I’m going to play with your cute little teats with my mean little blade here.” Twilight twisted it in the candlelight, admiring how the wax caused the dim flame to absorb the light in some places, the metal scattering it in others. Almost as pretty as her tied-up lover. Almost. “And then I’m going to kiss it all better.”

“Nghh.”

Twilight remembered the voice, the hard one, the one like high authority and deep lust, let it crack out again and watched Rainbow’s eyes as she did, “But that’s still not an answer to my question, little Rainbow. Pour or—”

“Pour!”

Twilight dripped three pinpricks far lower than she’d started, right near Dash’s navel, and Dash squeaked each time. “Don’t interrupt your Bookworm, little Rainbow.” Again, she snapped her voice, and Rainbow shuddered as much at it as the lingering nearly-burns, “What do you say?”

“Sorry...”

“Good. I told you I’d teach you what that word means, didn’t I?”

“Yes, mistress.”

“Mistress?” Twilight asked in mock-surprise, keeping the voice up to hide the genuine shock she felt. That was a new one. “I didn’t ask to be called that, did I?”

“N-no.” Rainbow stammered, and judging by the blush, that one was all nervousness. Twilight’s smile didn’t widen so much as deepen when she realized what that meant.

“Oh, dear, my little Rainbow,” she crooned teasingly, holding the candle over her teats like a threat as much as a promise, “You’ve been thinking about this for a while, haven’t you?”

Rainbow shook her head, and there was another drip right on the aerola, not quite on the nipple but enough that Rainbow shrieked. But still her hips thrashed more than her legs. Twilight took to scraping the built up wax absently, crawled up from between Rainbow’s legs and besides her, where she could kiss her cheeks, her lips, her neck at will.

Did one of each.

“Mistress isn’t just a word you just say, little Rainbow,” Twilight crooned like honey and smoke in Dash’s ear, “I told you not to hide from me, didn’t I? I told you I can see right through you. And here you are, trying to lie to me.”

Dash was panting fast, rapid shallow breaths, her pupils utterly blown out. Twilight could hardly even tell what colour her eyes were supposed to be beneath them. She was really liking this, wasn’t she? Twilight had to admit, she hadn’t even thought to touch herself since she’d lit the candle. Oh, she burned desperately for something to fill her and to fuck her, that was still true, but... the role had been more important. In a way, it had been more satisfying. Which made her think...

“Is that why you were teasing me so much in the foyer, little one?” Twilight asked curiously, “Those were fantasies you’d had about me, and you were just too nervous to ask?” Dash’s eyes darted to her face, were watching Twilight intently, jerking from her eyes to her lips. Twilight hummed thoughtfully, “No? No, it wouldn’t have been the same... You didn’t want me to just have control. You wanted me to take it.”

Dash whined, nodding, words less important than need.

“Little Rainbow, putting all these ideas in my head, when there’s just one little detail you didn’t count on.” The ropes tightened just a little, but enough that there was that beautiful ‘Thwip!’ sound of friction, of rope sliding on rope, like italics and underscoring what she was saying, “I’m far more creative than you are.”

Rainbow gulped nervously, good.

Twilight poured the wax in a curve underscoring Dash’s breasts. Now that the thrashing wasn’t worrying her so much, she could just appreciate the intensity of the reaction she was getting. All of Rainbow’s muscles seemed to be pulling and tightening at once, desperate for something to fight against if the ropes weren’t in the way.

But they were. They always were, and they both knew it, which was an exciting thought.

Twilight put the candle down to let it build up heat again, taking the letter opener and again sliding the cool edge of it against Dash’s taut skin, stripping it of the wax. Every time the edge pressed down, Dash shivered, her teeth chattering as her jaw tried and failed to clench down. She was constantly whining now, something low and at the edge of hearing, but it was always there, occasionally cut off by grunts or a long moan. Especially if Twilight rolled the tip of the blade directly against the nipple.

They’d played with Dash’s breasts before, and Twilight had been astonished just how much more sensitive they’d been than her own. Compounding that with the heightened sensitivity the wax gave her made Dash something beyond putty in her hooves, and the rise and fall of her breathing almost musical.

“Are you ready for me to get creative, little Rainbow?” Twilight asked, trying to keep the amusement out of her voice, trying to keep it that cool and authoritative thing.

Dash’s neck went limp, let her head flop miserably back. “This isn’t creative already?”

Twilight smiled. No, no this hadn’t been.

She focused her magic on herself. She hadn’t had much practice with this spell, and she’d never done it with anypony else... she bit her lower lip, even as she concentrated. Tried to focus.

The magic centered in her core, pressing outwards. Her clit thrummed with heat and pressure, building outwards. The emptiness she’d felt in her gut lowered, became two tight and heavy balls which pulsed with energy and... wow. Wow, she’d never cast this spell so turned on before. She’d gone from feeling a painful emptiness to a painful fullness faster than she’d expected, and it was making her impatient.

She climbed on top of Dash, her knees holding Dash’s thighs apart, nibbling at the nape of the pegasus’ neck. She let her new weight rest on Dash’s stomach, felt her stiffen and rock back from it, press herself deeper into the bed.

“Twilight, you didn’t...?”

Twilight smiled quietly to herself as she crawled up to nibble on Dash’s ear, letting her new cock trail precum up across Dash’s sensitive stomach. “You had your chance downstairs. Now I get to be creative, little Rainbow.”

Dash’s hips bucked at that, squeezing Twilight’s cock between them. It was her turn to gasp now, sharp and quick. She hadn’t expected that, hadn’t expected to be so sensitive. She nipped Dash’s ear again.

“What happened to Mistress?” she breathed, “I actually rather liked that.”

Dash was silent. Wasn’t used to saying it, obviously. But there was always practice. “Sorry, Mistress.”

Twilight’s cock twitched at hearing that, and Dash squirmed as she felt it against her stomach. “Good. Now, do you want to get properly fucked, little Rainbow?”

Rainbow hesitated, shook her head. That was surprising - this was the part she’d gone too far? Twilight leaned back so she could study Dash’s face. Dash definitely looked hesitant, wasn’t making eye contact, looking down and away... but the blush, that was more intense than she’d seen it all night.

“Can you... ah... Mistress, would you let me choke on your... thing...”

Twilight felt her balls twitch, tighten at that. Emphatic yes. Still, there had to be a way about it. “Mistress does not have a thing, little Rainbow. She has a penis, or a cock. Not a ‘thing’.”

“S-sorry.”

“Sorry?”

“Sorry Mistress.” Dash was drooling now, just slightly, and her mouth just wouldn’t quite close. Like her tongue just didn’t quite fit in her mouth. “Please can I suck your...” She paused, swallowed, “cock?”

Twilight crawled up the bed until her knees were straddling Rainbow’s head on either side, her new member resting against Dash’s throat. Twilight leaned her weight against the top of the headboard, arching over Rainbow and looking down at her eyes, pupils blown out so wide you could hardly tell what colour her eyes were, her mouth lolling open and tongue resting on her bottom lip, waiting.

Oh, oh wow. Wow, that was... more intense than Twilight expected it to be. She positioned herself against Rainbow’s mouth, and stars exploded across her eyes when the hot, wet tongue first made contact. Spells made her way more sensitive than she’d expected...

Then Rainbow bobbed her head forward, and Twilight entirely forgot how to breathe.

Dash was inexperienced, certainly. Almost too enthusiastic. Twilight had to press her head back a moment just to catch her breath, before things got so sensitive they were painful. “Good girl,” she breathed, “But Mistress needs to...” something. Needed to think. Dash’s eyes looked desperate, almost hurt at the delay.

“Suck less,” Twilight commanded rather than asked, and another little shudder rocked Dash’s body, “use your tongue more. Let me control the motions, little Rainbow.”

Rainbow’s eyes half lidded, drunkenly, and Twilight took that as her instructions being understood. She held Dash’s head between her knees as she started rocking her hips backwards and forwards. She slid smoothly over the tongue, Rainbow being careful even now not to let her teeth touch, just rolling the back of her throat—

Ah!

—press against the head, squeeze against it. Twilight pressed a little deeper, held it until tears were forming in Dash’s lidded eyes, then pulled out completely, let Rainbow cough and splutter and get her breath back. Then Twilight pressed in again, further, until it felt like Dash was trying to swallow the whole thing down.

Fuck.

Twilight pulled out, threw herself on Dash desperately before she got a chance to breathe, kissed her hard on the lips and forced her tongue into Dash’s mouth hard, hoof pressed to Dash’s throat. When she tore herself back they were both panting, ragged and desperate.

Twilight was desperate now.

She pressed a foreleg down and shifted until she was lying over Dash again, her wings pulling Dash up into her, Dash arching her back so she was pressed into her, positioned herself against Dash’s hot, dripping cunt...

Good girls didn’t think words like that, but Mistress didn’t care about that right now.

She pressed herself, forehead to forehead with Dash, Dash’s skull resting down along the length of her horn, staring into her eyes, she wanted to be looking in Dash’s eyes when she pushed forward.

Twilight pressed forward, pushed against the resistance, then Rainbow was around her. Little Rainbow’s eyes started to roll up in her head, another gasp-squeak, and Twilight kissed her hungrily, tongue sliding easily underneath Dash’s and flicking upward.

Rainbow was tight, the bones of her pelvis pushed back at soft angles, and the hot massaging motion of muscle was all Twilight could conceive. Her entire sense of self was focused on her hips, now, and Rainbow against her mouth, and the protests of her legs and the tightening of the muscles in her back were whispers below the screaming.

Dash wasn’t screaming. Her little Rainbow would need to breathe to do that, and Twilight wasn’t breaking the kiss. They took breaths in short, desperate gasps like drowned ponies, then Twilight forced them back down again.

She was fast—

Ah!

—and hard—

Ah!

—and Dash wasn’t resisting, was struggling against the ropes to arch herself more into Twilight—

Aah!

—to pull Twilight in deeper—

“Cum for me, little Rainbow.”

—and then Dash bent her chin to her chest and cried out, forcing Twilight out of the kiss, and her legs pulled towards her stomach until the ropes frayed, and she spasmed. Hardest was in her gut, against Twilight, where her pelvis held Twilight inside her like a vice.

Twilight couldn’t hold back if she wanted to, and she didn’t want to.

She growled, low and bestial, and bit down on Rainbow’s neck as she came hot, the strange sensation of her balls tightening and rolling along her shaft, firing thick bursts as she fucked Dash through the orgasm, kept pumping her hardest when she was so sensitive.

Rainbow cried again before going limp, head lolled against the pillow, breathing fast and shallow as her heart thrummed.

Twilight collapsed against Rainbow’s chest. She peppered Dash’s cheeks with soft kisses and she stayed half-limp inside her, just enjoying the heat and the closeness. Enjoyed the feeling of the last few spasms squeezing against her. It wasn’t long before the tightness became too much, and Twilight had to pull out—but Dash’s last, sharp gasp soothed her disappointment.

There was a gentle glow as the ropes came untied. They were fun, but they were also getting in the way of cuddling. As soon as she felt the release, Dash grabbed Twilight and squeezed, burying her head in Twilight’s chest, snuggling right into her.

“Just so you know,” Dash said, still nuzzled below Twilight’s jaw, “You’re mine, next time, Bookworm.”

“We’ll see.” Twilight kissed Dash’s forehead again, smiling to herself. “Depends on how far you push your luck.”

“Is that a promise, or a threat?”

“I think that’s for you to decide,” Twilight said with a giggle.

Rainbow nodded into her chest. “Love you.”

“Love you too.”

They lay there for a little while, just holding each other, content. Enjoying the warmth, and the closeness.

Dash cleared her throat, leaning back and looking up at Twilight. “Ah, not to kill the moment, but I’m covered in wax and... sticky. You mind if I go run a bath?”

“That sounds really good right now, actually. If we share, this spell hasn’t worn off yet... You want to go for another round?”

“... yeah, alright.”
