Short sweet gay sex fluff. Contains anal. A little bit of oral but mostly anal. With Dusk on the bottom. Also Butterscotch has a gigantic dick in this. But then again he does in all my stories.

Dusk Shine's Latest Experiment

“Dusk? Dusk? Are you home?” Butterscotch’s voice echoed through the halls of Dusk Shine’s palace. He shivered — this place was too big and empty and he did not understand how Dusk could live here all alone. The slightest noise echoed through its purple crystal corridors, and the countless doors, stairs, and side halls gave the lurking hob-goblins of Scotch’s imagination ample opportunity for surprise.

“Hi, Scotchie!” said Barb.

Scotch yelped and hid behind a potted plant.

Barb, who was sitting at the top of the stairs to the kitchen eating chocolate ice cream, rolled her eyes and licked her spoon. “Yep. It’s me. The terrifying dragon.”

Scotch stuck his head out from around the edge of the pot. “I’m sorry, Barb. You startled me.”

Barb shrugged. “You want some ice cream?”

“No, too much sugar makes me jumpy,” said Scotch, wriggling his lean, long-legged body out from behind the potted plant. “Is Dusk awake? I know it’s late, but Blitz is away on maneuvers and I’m so lonely I can’t sleep.”

“He’s up in the library, in a tizzy. He found some interesting books.” Barb narrowed her eyes slyly. “Dusk said I was too young to look at them. But you might enjoy them.”

Scotch blushed, and his eyes widened. “Naughty books?”

Barb shrugged. “Go have a look. I’ll be down here. Guarding the ice cream. Try to keep the noise level down, okay? I have innocent ears.” She waggled her ear-fins up and down.

Butterscotch gave Barb an anxious look and took the central stairwell up to the library. He could hear Dusk’s hooves tapping frantically across the floor, and his voice muttering with consternation. “I’ve been wrong this whole time. Do they really do that to each other?”

Scotch flattened his ears against his head. He’d come to Dusk’s place partly because Dusk kept late hours. Bubble Berry and Elusive often stayed up late too, but they were both very… intense. Passionate. Dusk Shine was usually safe — he liked to drink tea and read in a dignified and princely way. Except when he had a new idea. Then he was dangerous.

Butterscotch reflected that he needed to find some more boring friends.

There was a crash of falling books from the library. Scotch gathered all of his courage and stuck his head through the library door. “Duskie? Are you okay?”

“Butterscotch! Thank Harmony you’re here!” said Dusk Shine, rising up from a pile of hardcovers, one lying open on top of his horn.

Scotch blinked “Me?”

“You’re gay. Maybe you’ll be able to explain this to me.” He rushed over, grabbed Scotch by the withers, and flew him to several art books that were lying open on the floor.

“Look!” he said, waving his hoof at the illustrations “Look!”

Scotch blushed. On top of the pile was a book with photos of an ancient Pegasopolan frieze depicting an older pony taking satisfaction from a much younger pony. Both of them were enjoying the experience, judging by the state of the impressive male equipment the sculptor had chosen to depict. The next book was a series of erotic lithographs from a century or so ago, showing two stallionly, mustachioed ponies taking turns putting their… um… members under each other’s tails. Finally, there was a set of compromising photographs of Prince Blueblood and Fancy Pants from a magazine that to pony at the newsstand kept behind the counter. Scotch had never looked at those magazines. He was too shy to ask.

“Sodomy!” gasped Dusk Shine, waving his hooves at the images. “Sodomy is real!”

“Okkkaaaaay,” said Butterscotch, looking sideways at Dusk Shine. “You didn’t know that? Literally, all of your stallion friends are gay or bi. How could you know know that, Duskie?” He felt awkward. The pictures were… well, they were all very exciting, and the prince was a super handsome pony, as princes ought to be. Big, and strong, and noble-looking, with a magnificent wingspan and a floppy ragdoll mane that was always falling in his eyes. A little soft around the middle, sure, but that just made him cuddly. Scotch thought it would be fun to cuddle Dusk Shine. His body thought so too, and now that the conversation was on the topic of sodomy Scotch had to keep all four of his legs pressed together to hide that fact. Scotch, in spite of his slim build, was well endowed to the point where his cock poked out from between his forelegs when it was all the way up.

Dusk Shine pushed his mane out of his face. The look on his face — confused, concerned, aroused — make him even more beautiful than he normally was. “I… I don’t… I just assumed… I don’t know. Do you and Blitz do that?”

Scotch nodded, grinning from ear to ear.

“Doesn’t it hurt?” asked Dusk.

“Not if you do it right,” said Scotch in a sing-song voice. His pulsed, so hard it almost hurt. He had to press his forelegs together to hide the tip. It was futile — even if he somehow hadn’t seen the massive erection, Dusk would be able to smell the pre drizzling from the tip.

Dusk put his hooves on Scotch’s shoulders. “Scotch. Teach me how to love another stallion!” Speaking of smelling things — Scotch’s nostrils flared. He let his eyes flick down the prince’s barrel and saw that is cock was out and hard, too.

Scotch’s wings shot out to either side, rigid. “Um… okay. If you want to?” As Dusk’s experiments went, this one was way less scary than average.

But suddenly Dusk turned away, clutching his head. “No! What if Blitz finds out! Everything would be ruined! Your love! Our friendship!”

Scotch blinked. “Um, no?”

Dusk looked over his shoulder at Butterscotch. “What?”

“Um, Duskie, Blitz doesn’t care. He’s… monogamy… isn’t really a thing with him.” Scotch ducked his head. “He needs sex, like, three times a day. Minimum. I can’t handle that. I need my alone time.”

Dusk’s eyes widened. “Oh.”

“And he says its fine if I sleep around too, as long as I tell him all about it.” Scotch grinned. “So if you don’t feel weird about it…”

“Wow,” said Dusk turning back around to face Scotch. “I do feel weird about it? But in a good way? Like, an excited way. So what do we do?”

“Well,” purred Scotch, slinking over towards Dusk like a cat, ”We could kiss.”

“Kissing another stallion is really gay, Scotchie.”

Scotch nuzzled Dusk’s face, ruffling the fur of his cheek with his snout. “And sodomy isn’t?”

Dusk gulped. “It’s just… kissing is so intimate.”

Scotch batted his eyelashes at Dusk. He didn’t often get the chance to be seductive, what with Blitzie being so eager, and he was relishing it. “Oh, but we’re such good friends, Duskie. Don’t you want the opportunity to try something that will bring us even closer together? Don’t deny the gay. You want it, or you wouldn’t have shown me those books. Embrace it, and it will be so much fun.” Scotch planted a soft kiss on Dusk’s cheek and smoothed the fluffy fur on his chest with his hooves.

He could see Dusk Shine cogitating, testing the soundness of Scotch’s argument in favor of gay kissing. Scotch bit his lower lip. He didn’t want Dusk thinking his way out of this — he wanted his gay virginity with every fiber of his being. He took the other stallion’s head in his hooves and ran his tongue across his lips. Dusk opened his mouth and Scotchie pressed his attack kissing him deeply. Trembling hooves rose to stoke Scotch’s wings and the sides of his chest. Scotch melted against the heavier pony, losing himself in the kiss.

Their chests heaved together, sharing passion. Scotch shifted his hips forward so that their cocks were rubbing together, as well — Scotch’s huge pink member rubbed against Dusk’s smaller one like two duelist’s like crossed swords.

“Oh no,” moaned Dusk, looking down. “I’m too small! I always knew I was too small!”

“Dusk, no! Don’t be ashamed!” crooned Scotch, cradling the two shafts together, stroking Dusk Shine’s cock with gentle hooves. “You’re a good size! It looks like you’re about average! Anyway, Blitz tells me I’m really big. And you know what?”

“What?” said Dusk.

Scotch leaned over to whisper in Dusk’s ear. “You have a bigger cock than Blitz does.”

Dusk gasped. “I do?”

“You have a bigger cock than my boyfriend,” he purred, mashing the two shafts together. “A little longer, but much, much thicker. So do you like it when your dick touches mine?”

“Yes. So very yes,” said Dusk.

“Do you want me to suck it?” whispered Scotch, fluttering his eyelashes.

Dusk nodded frantically.

Scotch kissed down Dusks’ neck and chest. He nuzzled his friend’s flare and licked along the scalloped edge.

“Oh, Harmony!” moaned Dusk, stamping his forehooves. “It feels better than anything I’ve ever felt!”

“Stallions know what stallions like,” said Scotch. He slid his mouth over Dusk’s flare, sucking it gently and playing with it with his tongue. He loved how strongly Dusk was responding to him. It made him feel sexy, and that made him feel confident. Which was a big deal for Scotch. He let out a muffled giggle as a spurt of Dusk’s salty-sweet pre spurted onto his tongue. Humming happily, her hooked his hooves over the shaft, and sucked it deeper, slowly working it into his throat.

“Ybh. Ngh. Aye. Oh. Oh, buck!” moaned Dusk, hooking his hooves around the back of Scotch’s head, and pushing him further down the shaft Scotch was happy to let Dusk take control. He cupped Dusk’s balls in the frogs of his hooves, rolling them against each other as Dusk plowed his throat. He watched the thick purple shaft bobbing in and out of his throat, glistening with spit where it left his lips. It was so beautiful. Duskie had a pretty cock. Scotch was so wrapped up in sucking it that he almost didn’t notice how his friend’s thrusts were becoming more irregular, and his breath more ragged. Oh no! He might come! If he came he might lose all interest in sex! That was the problem with stallions — it was all about Mr. Dick. Scotch was used to servicing Blitz when he himself wasn’t in the mood, but he was the bearer of the Element of Kindness. Other ponies might not be as generous.

Scotch wriggled out of Dusk’s grip. His cock popped out of his mouth, spraying spit across Scotch’s face and Duskie’s belly.

“You…you stopped!” whimpered Dusk. “Why did you stop?”

“You said you wanted to try anal sex,” said Scotch, smiling coyly. “Its okay if you changed your mind, but I was looking forward to it.”

“I do,” said Dusk. “What do we do?”

“Well, do you want to be top or bottom?”

Dusk raised an eyebrow. “What now?”

Scotch giggled. “Do you want to put your thingy up my butt, or my thingy up your butt? I like it both ways, so you get to pick.”

“Ohhh,” said Dusk.

“I thought you’d read about this?”

“I really hadn’t gotten past the pictures,” said Dusk, blushing furiously.

“Well, why don’t you bottom. It’s easier,” said Scotch.

Dusk looked at Scotch’s cyclopean erection. “Seriously?”

“Don’t worry,” said Scotch. “Pony insides are super stretchy! I’ve topped Blitzie a billion times, and he’s smaller than you. We will need tons and tons of lube, though.”

“I have just the thing,” said Dusk, and teleported them up to his bedroom.

✭☆✭☆✭☆✭

They decided that it would be best to warm Dusk’s bottom up with a toy, first. Dusk didn’t have any, but making one with his magic was easy enough. “A force field,” explained Dusk. “I stabilized it so that it’ll keep cohesion for a few hours without having to maintain it. You know. In case I’m distracted.”

“Where’d you learn that trick?” Scotch stroked the floating lozenge shape. It was hard, almost like glass, but warm to the touch, and about half the length and thickness of Scotch’s massive cock.

“Oh, Gleamy taught me. She knows everything about force fields.”

Scotch raised an eyebrow. “Your sister taught you how to make a magic dildo?”

“Oh, no! Only how to stabilize a force field. Gleamy would never…” Blitz’s eyes widened slowly. “Oh gosh, you don’t think she…?”

Scotch decided it was time to change the subject. “You’ll probably want to flare the base out a little,” he said. “So we don’t lose it inside of you.”

“I could just dispel it,” agreed Dusk, extruding a sturdy grippable base from one end of the dildo, “but then I’d have to make a new one.”

They were lying together on the bed as they spoke, idly rubbing their dicks together. It was fun playing with Dusk. He was very matter-of-fact about everything. He seemed more interested in the process than getting to the orgasm. With Blitz, it was always ‘cum cum cum’ all the time. That was good; it meant Scotch got to drink gallons of his boyfriend’s creamy, citrusy jizz But it was good to get to take his time, too.
“Where’s the lube?” said Scotch.

Dusk levitated over a gallon mason jar of clear goo labeled ‘animal birthing agent’. “I made this to help the Apple family with their cows. It’s become very popular around town. Even with ponies who don’t have any pets.”

“I don’t think they’re using it for its intended purpose,” suggested Scotch, blushing.

“Yeah, I caught on pretty quick. I use it when I…” he waved his hooves vaguely. “You know. When I take care of things.”

Scotch uncapped the jar and poured some goo out onto his hooves. It trickled down his foreleg, slimy and viscous. “This is… hmmm. This seems really good. Do you mind if I…”

Dusk kissed Scotch timidly on the lips and rolled over onto his back, lifting his hind legs in the air. “Please be gentle.”

Scotch blew his mane out of his eyes and giggled. “Who do you think you’re talking to?” He settled in between Dusk’s hind legs. Dusk’s ass was broad and firm, two big slabs of muscle padded by rounded curves of fat. He nosed under Dusk’s glossy purple balls. They were heavy with cum and smelled musky, sweet, and slightly bitter like coffee and chocolate. He licked down the prince’s taint to his plothole. It was smooth and silky and perfectly clean. He inhaled, drinking in its heady scent, then ran his tongue around it in slow circles.

“Oh!” said Dusk. “That feels… funny…”

“Funny good or funny bad?” purred Scotch.

“Funny don’t stop,” said Dusk, wrapping his hind legs around Scotch’s head.

Scotch spread Dusk’s buttocks with his hooves so that he could get a glimpse of the prince’s pink insides. He pressed his tongue against the tiny opening, wriggling it in, tasting Dusk’s salty skin. He was so smooth down there, so clean and tasty. He tongue-fucked him for a while, listening to his friend moan as he explored his tailhole. When his tongue started to get sore, he pulled the bottle over with his wings. He spread the goo over Dusk Shine’s ponut, then he got another hoof full, and another, until it was soaked with lube and goo dripped down onto his dock.

“Are you ready?” Scotch asked, raising his head so he could see Dusk’s face.

Dusk bit his lower lip. “You’ll stop if it hurts, right?”

“The second you tell me to,” said Scotch. “I’m good at this, though. You’ll be fine.” He pulled the magic dildo over from where it floated nearby and pressed the smooth round tip against Dusk’s asshole. He pushed gently, rolling it back and forth in the goo for a while, then pouring more goo over the shaft. He didn’t go far, only an inch or so, pushing Dusk’s ass open, then backing off. The dildo was semi-transparent, letting him see some of the pinkness of Dusk’s insides through it. Scotch found this both gross and fascinating.

“Are you feeling all right?” said Scotch.

“It’s weird, but I’m getting used to it,” said Dusk. “I feel like it’s not really in me, though? Can we go a little deeper?”

Scotch gulped. “I’d love to, but I don’t want to hurt you. Remember what I told you?”

“Push down, and don’t panic,” said Dusk. “I can do that!”

“All right,” said Scotch. “Here goes.” He pushed the dildo against Dusk’s ass with both hooves on the base. The prince’s body resisted for a second, but then he opened like a flower and the shaft started to slide into him, lube glistening as it moved.

“Oh, Harmony!” shouted Dusk.

“Are you okay?” said Scotch.

“W-weird!” said Dusk. “Doesn’t hurt. Experiment… the experiment must continue.”

Scotch grinned and pushed gently. His friend’s ponut spread out around the dildo, stretching into a thin ring of flesh around the gleaming shaft. Scotch licked his lips as he watched the flesh around it pull in and out. He humped his hips, rubbing his cock against the silky sheets of Dusk’s bed. He wanted to fuck Dusk Shine, wanted to feel his body around him, but he had to wait until he was sure Dusk was ready.

“It’s starting to feel… really really good,” moaned Dusk. “It’s touching something inside of me. The prostate, right? Anal sex is supposed to stimulate the prostate in males.”

Scotch rolled his eyes. “We call it the ‘special spot’.”

Dusk giggled. “That’s so gay.”

“Um, yeah,” said Scotch. “It’s pretty gay. Hey, float over that mirror. I want to show you something. Yeah, Right over here.”

Scotch leaned back away from the mirror and pushed Dusk’s thighs apart so that Dusk could maneuver the mirror into place. Dusk gasped. “It is it really…?”

“All the way in,” said Scotch. “You’re a natural.” He pushed on the base of the dildo, rocking it gently against Dusks’ ass.

“Can we take it out and do you now?” said Dusk, tugging at the base with his magic. “I want to try you!”

“Not so fast! Not so fast!” said Scotch, “You’ll hurt yourself! You have to take it out slowly!” He rose up over Dusk, wings spread, and laid his cock shaft over the prince’s. “Are you sure you want me to fuck you? We could just grind with that dildo up your ass. Nothing too challenging. You’re already doing super well for your first time.

Dusk stroked Scotch’s chest. “It’s okay buddy.”

“I don’t want to put any pressure on you,” said Scotch. “We can totally move at your pace.”

“Scotch.”

“I mean, even just cuddling is fine, if you want.”

“Scotch.” Dusk shine bopped him on the nose with the slimy end of the dildo.

“Oh!” said Scotch, wiping goo off his nose.

“I can feel a draft up in there,” Dusk said with a grin.

Scotch pulled his hips back a very long way, aiming his cock down between Dusk’s cheeks. “I’m a lot bigger than that dildo, you know.” He ground his wide, scalloped flare against his friend’s gaping ponut.

“I noticed that!” said Dusk, arching his back with pleasure. “Only one thing for it: more lube. How big is it, anyway?”

Scotch blushed as Dusk floated over a full jar of lube and poured it out over Scotch’s long gently curved pink-and-yellow mottled shaft. “Oh, I never measured. It’s too embarrassing. I’m not as big as Applejack, that’s all I know. I’m bigger than any other colt I have sex with.” Dusk’s homebrewed lube was nothing short of miraculous. Scotch took one thrust, and his flare vanished into Dusk’s near-virgin ponut with a soft pop. The prince’s insides cradled his cock, hot, silky, and punishingly tight.

Dusk gasped in surprise and pleasure, and pushed his hind hooves against Scotch’s lean ass cheeks, pulling him in. “That’s amazing. Applejack must be… gigantic.”

“He’s just… oh, it’s inconvenient how big he is but I’m not complaining. And Berry can just put that thing inside of him like it’s nothing. Lube it up with some butter and it’s gone.” Sweat trickled down Scotch’s brow as he slid in inch by inch. He looked down so he could watch his cock vanish between Dusk’s strong cheeks.

Dusk looked alarmed. “That’s… wait, is this the butter he uses to bake with?”

“Don’t… oh, Harmony… Don’t worry, even a marginal lube up on Applejack takes a whole pound of butter.” Scotch groaned as his flare sank past the tight grip of Dusk’s rectum into the warm, hot, still-snug silkiness of his bowels. “Hey, you’re doing really well for your first time. I don’t mean to accuse you of anything but, um, are you using magic?”

Dusk responded by taking Scotch’s head between his hooves and pulling him down into a long, wet kiss.

Scotch pressed his affections. And his cock. He shuddered as his friend’s silky insides embraced him. Slick with lube, his cock slid against Dusk’s inner skin. He pushed deeper and deeper, Dusk body accepting him effortlessly. The two friends writhed together, faces locked, tongues sliding against each other. Dusk’s hind legs squeezed him, wrapped around his ass, pulling him forward. His long, delicate purple cock ground between their bellies, pulsing with his heartbeat, drooling pre into Scotch’s chest fluff.

“Oh, Scotch!” moaned Dusk, arching his back, wings spread across the bed. “Scotch it feels so good!”

“Do… you like being fucked?” said Scotch, his voice trembling.

“Scotchie I love being fucked up the ass.”

Scotch ground his teeth. sweat soaking his brow as he struggled not to cum immediately. “If you say things like that I’m going to squirt! Don’t say things like that!”

“Wouldn’t mind if you squirted in me. But… Just a little longer…” said Dusk.

Scotch drove himself ball deep in the prince’s perfect ass, and held still, willing his balls not to disgorge their load. He felt his friend’s body clench all around him, powerful muscles slamming down on the base of his long thick cock. He felt Dusk’s balls tighten, and he felt jizz pumping through his cock. He locked his mouth over Dusk’s again just in time, so that the whole load sprayed the undersides of their jaws and soaked their necks. The smell of Dusk’s musky cum made Scotch lose his reason. The fur along his back all stood on end. He pulled back until his medial ring plucked at Dusk’s ponut, then slammed forward, making his friend cry out. He did this again, and again, and again. Dusk broke their kiss to gasp, and Scotch dug his teeth into the side of Dusk’s neck. Coffee-and-chocolate flavored cum filled his mouth.

A greenish-white light flashed before Scotch’s eyes. A wave of burning, tingling pleasure rippled through his body. He tossed back his head and let out an effeminate, almost startled yelp, in contrast to his masculine thrusting just seconds ago. He gasped, feeling his cock pulse as he filled Dusk’s guts with his seed.

Dusk reached up to stroke his cheek. “Scotchie are you okay?”

“Fine… I’m fine… I just… it felt so good! Oh my gosh, are you okay? Did I hurt you?”

“No, that was really fun,” said Dusk. He lowered his eyelids. “Thank you for helping me with my research. So. Am I gay now?”

“I don’t know. What were you before?” Scotch wiggled his hips, trying to pull his suddenly extremely sensitive cock out of Dusks’ suddenly far too tight ass.

“Too busy to think about it, I guess?” He gulped. “I feel… kind of closer to you now. I hope we can do this again?”

“Yes,” said Scotch, finally sliding out of Dusk’s body with a soft pop and a sudden rush of fluids. “Very yes,” he said closing his eyes and rolling over to sleep big spoon with Dusk. “Can I sleep here tonight?”

“Very yes,” said Dusk, wriggling back against him.

Minutes later, they were both asleep.
