"Alright, I'm back."
Dusk Shine paused, then smiled. Of course there was no response.
Closing his front door with a spark of magic, the unicorn trotted toward his library's central table. He deposited a few bags of groceries there, and with a quick spell, preserved them indefinitely. His ear twitched to the sound of fabric moving upstairs.
"Elusive was at the market, you know," he said, levitating items out of bags and whisking them away into cupboards. "Apparently his brother wants to go camping with him, so he's trying to figure out what meals to pack. He didn't seem too eager. Said something about 'nature being both a bane and muse of creativity'."
Dusk paused and listened again. Nothing.
"He asked about you. Asked about us. Mostly about what we've been up to lately, on account of not seeing us much."
Another ruffle of fabric.
"I told him we're doing great. Dates, enjoying each other's company, mostly. Didn't elaborate past that because...well, knowing him, he'd probably gasp and startle a lot of ponies."
A grunt accompanied the shuffling now. Dusk turned his attention to his stairway.
"Anyway, was that adequate? Honestly, I couldn't think of anything else to do but grab groceries. Not much else fits your fifteen, twenty-minute sweet spot."
Dusk took his time ascending, watching his bedroom unfold before him. The sun bathed his bed in brilliant light and illuminated the cerulean pegasus bound there. Flat on his back, Rainbow Blitz sported two pairs of hoof anklets, a custom binder for his wings, and a deep red ballgag to accentuate eyes full of fire. His head laid by the end of the bed, just close enough for those with lewd intentions to reach.
Blitz watched Dusk approach with apparent excitement. When magenta magic brought his gag to life, he looked up, and the two locked eyes. Dusk’s smile grew sultry.
"You know, I was kinda put off by all of this at first, but seeing you like this is really starting to grow on me." Leaning forward, Dusk slid his hooves over his plum bed sheets, propping himself up above the stallion. "The proud, macho Rainbow Blitz tied up on my bed? Ready to please me whenever I want? I feel so spoiled."
His gag freshly removed, Blitz slid his jaw to and fro before putting on a smirk.
"Glad you approve. I guess you could say it was bound to get your attention. Turns out there's a whole bunch of ways to have fun that you won't find in books. So many things to try, to do. Namely me."
Dusk's cheeks reddened. Blitz's smirk grew.
"You're insatiable."
"Can't help it. You're hot."
"I'd argue you're more so."
"As if. I've never seen anything quite like you dropping your prim and proper librarian shtick to have some fun. All I gotta do is give you an excuse, a good reason to think with your dick, and you go all in. Hottest nerd I ever laid eyes on."
Blitz winked, and the unicorn blushed even more. Charm, even when crude, had always been his weakness.
Dusk lowered himself into a kiss in slow motion. The soft clasp of touching lips filled the room, and Dusk's heart began to race. He pulled back, but only to lovingly peck Blitz's snout instead.
"I could kiss you all afternoon and you wouldn't have a say in it."
"Is that a promise?"
"Maybe. Maybe I'm making a list in my head of all the ways I can enjoy this in the future since you love it so much."
Pulling himself onto the bed, Dusk closed his eyes and dragged his tongue along Blitz's sky blue coat. A deep, haggard breath was his response. He licked lower, down the stallion's stomach, and the breath became a moan. Again their lips touched, but this time Dusk maintained it, trapping the pegasus in a kiss he couldn't escape. He explored Blitz's mouth, probing every last crevice and corner, and upon finishing, started over.
Minutes passed before they parted. Blitz's cheeks had tinged red also.
"I think you're just looking for new ways to tire out my tongue."
"That'd only be to my detriment, wouldn't it? Maybe I'm just gauging your potential. If you can't handle my tongue in your mouth, I doubt you could handle much more."
"Try me, coach," Blitz retorted. His tone dripped with lust. With half-lidded eyes, Dusk smiled.
"Well, as much as I'd hate to rob you of your pastime making cheeky remarks, it is about time I give your mouth something more important to do."
"Oh, I love when you get flirty."
Blitz's wings twitched against his restraints, mirroring the twitch of his prick. Dusk stood up, but not before nibbling gently on a vulnerable ear.
"I'd say you should swallow any spit you don't want to end up drooling, but I think it'll happen anyway in this position."
Blitz swallowed on reflex, his heart a drum in his chest. He watched Dusk shift positions again, straddling his head with his lower half. There, Dusk spread his legs, and as lilac hooves sank into the bed's folds, Blitz felt his mind go blank, his coltfriend's cock staring him in the face.
"Open up."
Blitz opened his mouth on command.
"Good colt."
Euphoria pulsed through Dusk as his shaft slid between Blitz's lips, guided by the curve of his tongue. He let out a nigh-effeminate moan, and his whole body tensed at once.
Biting his lip, Dusk rhythmically rocked his hips, sliding in and out of his organic fleshlight. Within moments, his entire shaft was engulfed in heat and spit, his nutsack repeatedly pressing up against Blitz's snout.
"You think a nerdy librarian getting frisky is hot? Imagine my position. My athletic, alpha male coltfriend who tells me he wants to get facefucked all day, with breaks for tension. I had to hear it again just to be sure, but my hormones sure didn't."
Blitz squirmed in his restraints to flame his own arousal, grunting through a mouthful of fully erect cock. He opened his eyes, only to find Dusk’s undulating nutsack obscuring his view, the gentle taps against his snout becoming slaps. Every one filled his nose with a lavender musk, soap mixed with freshly shed sweat.
Blitz inhaled more sharply as Dusk began to thrust even faster. His mind had become a haze of lust. His eyes lazily rolled up to appreciate the crest of that ball sack.
Dusk whimpered. He jerked back his head, puppeteered by the intoxicating pleasure. "Your mouth feels so good. We've definitely found the ideal use for it."
Seconds ticked past a minute, then two. A watery mix of his own spit and Dusk's precum began to slide down Blitz's cheek. It rapidly cooled against the open air, a perfect contrast to the heat of sex filling his mouth.
"Oh my gosh, I'm getting close.” Dusk ploughed his coltfriend's face even harder, desperate to reach that sweet release. "W-where do you want it?"
Blitz let out a long, monotonous groan. He tightened his lips around Dusk's dick, forbidding him from pulling out.
"Still thirsty, huh?" Dusk managed to chuckle amidst a flurry of pants. "Maybe it's my taste you're addicted to. I never took you for the smoothie type, Rainbow."
Slurps and grunts were his only answer.
Again Dusk's body tensed, his every muscle burning in a combined effort to climax. He curled his head downwards, towards the fluff of Blitz's chest. The sweat, the exhaustion, the muscle tension—everything was quite literally coming to a head.
"...oh sweet Solaris, I'm gonna cum," the unicorn gasped, doubling down on his efforts. The sight of drool spilling from Blitz's mouth and dripping onto his bed sheets would probably irk him later, but for now, it only served to heighten his arousal.
The wet sound of lubricated cock sliding between lips sped up, only to slow down again. Dusk threw back his head, moaning desperately as orgasm shook his body. Ropes of cum now flowed and pooled below Blitz's tongue, sticking to the insides of his cheeks. Only after the final wave passed did Dusk slowly pull his length free with a satisfying pop. Strands of semen stretched from dick tip to lips for several inches, only breaking when Dusk stepped back, shaky in his afterglow.
He watched Blitz smirk and open his mouth again, showing off the impressive load before swallowing it.
"I say it again, you're insatiable,” Dusk chuckled.
"I only brag because it's the second best thing my mouth is good at."
"Let's focus more on the first thing, going forward. You're way cuter sucking my dick than you are being haughty and arrogant."
"Can't do it," said Blitz. He stuck out his tongue, now semen-free. "I'm a package deal. I suck and I sass and I just never stop."
The last of Dusk's breaths returned to normal, and he glanced out his bedroom window. The sun had climbed over the rooftops to the south, meaning they were now in the early afternoon. He looked at the bound pegasus.
"So then, have you had enough for today? I don't think it's far off to say that we've done nothing all day but have sex and buy groceries."
"I see this as an absolute win. And that depends—do you see yourself running any more errands, today? I'm certainly not going anywhere, and I'm sure I could squeeze at least a few more moans out of you when you get back."
Love, and all its patience returned to Dusk's eyes. Lightly flopping upon the bed, he straddled Blitz and demanded his gaze.
“I didn't even have to buy groceries today, remember? We moved it up so that you could enjoy your fantasies to the fullest. I'm actually caught up with my to-do list this week, which along with Barb being out, is why you've had me all to yourself these past couple days."
"Oh, that's right. Silly me. You must have jostled my brain while you were in there. Shame I have to start sharing you again soon. Sure I can't talk you into using that time spell of yours for a little rewind?”
Dusk brushed Blitz's still-erect cock with a flick of his tail. He kissed an exposed neck and relished the snorts of hot air that followed.
"As much as I'm enjoying you like this, I know it's because you still need to cum yourself. You think it’s about time we fixed that?”
“It’s your bed, your rules, hot stuff. You feel like sucking dick? It’s right there for you.”
Something obviously phallic twitched against Dusk’s flank, and lust again curled at the corners of his smile. With a hoof, he drew circles on Blitz’s belly, taking his time before speaking.
"You really are committed to being my toy, aren’t you? Alright then. Yeah, I could go for a drink, myself. You're paying, right?"
Blitz tried to respond, but a jolt of pleasure climbed his spine from his crotch. In a display of light, Dusk had repositioned himself, and now half of Blitz’s cock had vanished behind lush purple lips.
"Oh, this one has some kick." Dusk traced his tongue up Blitz's shaft, collecting beads of sweat and precum alike. "What flavor is that? ‘Wonderbolt Practice’? ‘Flight Training’? 'Morning Negligence'? A bit strong for my tastes, but not bad.”
Dusk ventured the bridge of Blitz’s cock head, and the pegasus convulsed. He readily elevated his crotch, inviting that warm, supple tongue to continue working him over. It took all of his strength to merely lift his head, to peer down his own belly and watch Dusk readily devour his dick.
He was merely a bystander to his own pleasure, and it was enthralling.
"I wonder if you'll be as salty as you were the other day. If this week has been anything to go by, I guess I should start bringing home fruits more often. I don’t know about you, but I’d like my drinks to be sweet."
"If it means more of this, you can feed me all the fruit you want." Blitz strained to string words. He let his tongue flop from his mouth, his eyes rolling back in ecstasy as Dusk meticulously licked over every last inch of him.
"Oh, you'll eat fruit, alright. And you're gonna get a whole lot more regimented in showering, too, if you expect me to keep this up. While a sweaty cock has its merits, you'll get my attention a whole lot more often with some nice scents. Maybe a nice raspberry, or blueberry. Those would be great to smell while going down on you."
"Sir, yes sir."
The teasing came to an end, and Blitz was put at the mercy of ceaseless, calculated head bobs along the entirety of his shaft. The room befell cries of bliss as he arched his back, his wings quivering in their bindings.
By the time an impending orgasm came as a pressure in Blitz's groin, his tip was poised to paint Dusk’s entire face.
With a brisk series of thrusts, Blitz came. Thick ropes of semen splashed against the roof of Dusk's mouth before dripping back down and soaking Blitz's cock. The pegasus fidgeted when the milky strands were licked from his shaft.
Falling limp, Blitz labored a pant. A magenta glow pulled at his restraints, and soon enough, the pegasus was able to stretch his wings across the bed. Lying still for a time, he cast an eye at Dusk, who'd looked away in a presumed search for towels.
It only took moments for a devilish gleam to come to Blitz's eyes. Even when fresh off the orgasm of his life, the athlete had stamina to spare, and he’d already spotted his prey. With a quick motion, he leaped upon the distracted unicorn from behind, pulling him back onto the bed.
"C'mere handsome," Blitz purred. "It's cuddle time."
Dusk giggled. He blushed at cerulean wings wrapping around him like a blanket, and hooves holding him underneath. He surrendered at once, sighing in content as he laid against Blitz's chest and nuzzled the layers of coat fluff.
"You wanna cuddle while still covered in cum?"
"Oh, I'm sorry. Did I say 'cuddle time'? I meant 'it's cuddle nap time', as in, 'I'm cuddle-napping you, and we're gonna take a nap together’. Top priority stuff, Dusk. You’re gonna have to forget about the non-essentials."
More giggling ensued. Secure in a tight seal of wings and hooves, Dusk could only squirm when both sought to tickle him. The tables had turned; now he was the one being trapped and tended to.
"Well, what if I want to wash off first? You might have swallowed the mess but I'm still pretty polished with spit."
"And you wanna wash that off? I'm hurt."
Blitz grinned. He pulled Dusk up to his face, forcing a kiss.
"...Besides, you're not going anywhere, not after working me like that. You had your chance to clean up. You chose to untie me first instead, so here we are. You're gonna be my cuddle buddy, sloppy dick or no."
Dusk closed his eyes as his tongue was made to wrestle with Blitz's. The wings holding him tightened, and suddenly, making out with Blitz or laying under his chin became the unicorn's only options. Their groins rubbed together as they kissed, and Dusk could feel their hearts beat in sync.
"My attentive protector is back, I see."
"He never left. Just took a break while our dicks were out to play." Ending the kiss, Blitz pulled the stallion to his chest, squeezing him tightly with all six appendages and exhaling through his mane. "He'll always be ready to come back and scoop you off your hooves, don’t you worry about that."
Dusk rubbed his cheek against the soft chest ready to become his bed. He shivered. He was perfectly nestled in a den of plumage, and it chipped away at his consciousness slowly but surely.
"Alright, you win. But I'm showering first thing when we get up, and you're coming with me."
"Sir, yes sir."
"By the way, have you packed anything for this weekend? Feels like you've mostly been over here all week. The convention lasts a few days and we both have copies of Daring Do and the Legend of the Lost Art to get signed."
"What, you think you have to remind me? I'm a closet nerd because of you. Don't worry about it, I'll just throw some stuff in a bag on the way out. I've already told Firestorm that I'll be gone till next week."
Dusk took a deep breath. He'd ignore his coltfriend's blatant lack of preparation, for now.
"Was Firestorm okay with that?"
Blitz shrugged. "He kinda glared at me, but he always does that. He'll get over it. That, or I'll fly a few hundred extra laps when I get back, no biggie. Either way, no way am I missing a Daring Do convention with you."
Another squeeze. Dusk's giggles grew quiet, bogged down with fatigue. He dug his hooves under Blitz's back to return the hug. When he moved his head to let out a yawn, Blitz audibly awed.
"Somepony sure is comfy, huh?"
Dusk gave a lazy grunt in reply, his head back to being little more than a weight on Blitz's chest.
"You and your naps," he mumbled. "Going out with you was the biggest mistake I ever made for my productivity."
Blitz snorted. He planted his nose in a streak of raspberry mane.
"Well I've never seen a pony love showers as much as you do, Mr. Thrice-a-Day. I think we've both had to adapt. You've learned to slow down and chill with me, and I've gotten used to smelling your body wash on all my things."
"You love it," Dusk mumbled again. He couldn't be bothered with any deeper arguments this time. His higher brain functions had long gone dark.
Blitz said nothing. For once, his wit and sass were shelved. He settled on a loving stare, and a slow, rubbing hoof along the unicorn's back to shepherd him off to sleep.
Properly saddled with a snoozing pony, Blitz laid his head back and sighed. The lazy comforts of sleep were all the more enticing, having weathered orgasm. Luckily, the sun spared them its glare by carving a path of light just off the corner of the bed frame. They were shrouded in shade, tucked away from the day outside.
Blitz closed his eyes, and as sleep came for him, he wore a sly little smile. His coltfriend didn't know it yet, but he'd already signed away the rest of his afternoon for cuddling.
Author's Note
Happy Pride Month, Everyone~
Much like Mine is Dorkier than Yours, this story rode down on a bolt of inspiration. As a gay man, I wanted to make something for pride month, which helped. And so I thought, why not make it even more special by making it my first M fic for this fandom? 
I wouldn't say I actively ship TwiDash, but I wanted to explore an idea I had for their relationship dynamic, and how I could best see it. Blitz, who is aggressively submissive in bed is dominant and assertive in all other things, be it general life approach or cuddling, while Dusk is romantically dominant in bed but happy to play the sweet boy who just wants to be held and loved, otherwise. 
Thanks for reading!
