“You all right over there?” asked Twilight, amusement breaking over her face.

“Yeah,” hissed Sunset. “I mean, it’s just blue balls. Wouldn’t be the first time Aria’s pulled this shit. Serves me right for giving him an audience.”

“So you were just trying to impress me?” said Twilight, shifting her eyes towards Aria.

“What? No,” said Aria. “A tall, beautiful woman from Equestria comes by, and I put on a show for her? What would that even accomplish? Making Sunset jealous, and horny, and pissed off, just the way I like her?”

Sunset groaned. “Aria might not consume negative emotions anymore, but he’s still got a keen sense for them. He may have thought he picked up a whiff of… insecurity… as I was telling him about the pony who succeeded under Celestia’s tutelage. Became an alicorn and all that.”

“Yeah,” said Twilight, laughing uncomfortably. “All that.”

Sunset slipped her hand under Aria’s ass, cupping one soft cheek and kneading it with her fingers. “Aria thinks he can make me jealous. As if there’s another woman who can give him what I do.” She ran her fingers along the outline of her cock, beneath the tight denim.

“She’s right,” said Aria. “I’m a slut, but I have standards. Until I find another girl who can serve up the Vitamin Dick that a growing femboy needs, I’m stuck with her.”

“Growing?” said Sunset, squeezing Aria’s ass. “Am I gonna see this booty get bigger?”

“Well, you keep filling it,” said Aria, squirming in Sunset’s grip.

Sunset looked past Aria, seeing the discomfort on Twilight’s face. “Sorry, Twilight,” she said, “We’re being kinda gross, aren’t we?”

“No!” said Twilight. “This is… informative. I wanted to know how the two of you are getting along, and… I’m definitely learning.” She’d certainly been watching Sunset and Aria intently, although the way she was wringing her hands in her lap made her seem uncomfortable.

“Well, we’re not going spend the whole day just flirting in front of you,” said Sunset.

“Well, yeah,” Aria cut in. “I mean, I can only flirt for so long before I need to get pounded. So we’d eventually move on to fucking in front of you.”

“Not what I meant, babe,” said Sunset. “We’re gonna grab lunch, hit the town, see the girls. Not put on a sex show for Twilight. She’s a princess - if she wants to see a sex show, she can just order her subjects to fuck in front of her.”

Twilight frowned, stifling a giggle. “Come on, Sunset, you know I can’t do that.”

“You can’t?” said Sunset wryly. “Well, now I’m really glad I didn’t stick with Celestia. You busted your flank to become a princess and you can’t even order ponies to fuck for your amusement? Next you’ll be telling me Prima Nocta isn’t a thing.” Sunset removed her hand from under Aria’s butt and stood from the couch, motioning for the other two to follow.

As Aria tried to stand, something pulled back against him. The t-shirt he’d been wearing as a skirt had gotten itself tucked between the couch cushions, and it snagged, coming loose from his body and throwing him off-balance in the process. For a moment, he was teetering over the coffee table, ready to fall - and then Twilight was on her feet, throwing out an arm to catch him.

“My hero,” said Aria, finding his balance. “Sunset really would have some stiff competition if only you had a cock.” He looked down at himself. “Well, I’m fully naked now. I’ll go get dressed.”

“Well, we are sort of on a schedule,” said Sunset, “Try not to… take forever…”

Aria was already on his way to the bedroom, but Sunset’s odd, hesitant tone made him turn around. He looked at Sunset, only to find that she was looking at Twilight Sparkle, her eyes pointed in the direction of Twilight’s skirt.

“Holy dick,” said Aria, his eyes wide with hunger. “You do have one.”

Twilight seized up in panic, then looked down at herself. Her hands shot down to her crotch, but she couldn’t make Sunset and Aria unsee what they’d seen: The foot-long shaft that had been tenting up her skirt.

Twilight grumbled. “I was going to make an excuse not to stand up right away,” she said, “but then Aria almost fell over, and....”

“Just popped out, huh?” said Sunset. “I’ve been there, girl. Not easy to keep one of those contained. Especially with Aria’s ass bouncing all over the place.”

Twilight tucked her cock back into her panties, still looking annoyed with herself. “Yeah, it’s… it’s really something.”

“So have you had that this whole time?” asked Sunset.

“Since before I met you, yeah,” said Twilight. She clearly wasn’t thrilled to be having this conversation, but she couldn’t see a way out of it.

“Why didn’t you mention it when you saw mine?” said Sunset. “Would have cut the tension. And to think, you came here accusing me of keeping secrets…”

“That wasn’t why I came here!” said Twilight. “And there’s a pretty big difference between you keeping your relationship with a former villain secret and me not volunteering information about my genitals-” She paused, taking a breath. “Sorry. Sorry. We’re past that.”

Twilight fell back onto the couch. “Okay, look,” she said, “The reason I didn’t mention it to you was… I was still getting used to having a penis. You were born with yours, right?”

“Yeah, that’s usually how people get ‘em,” said Sunset. Back in Equestria, ponies having both sets of sex organs was an uncommon but well-understood condition.

“Well, not me,” said Twilight. “Turns out that becoming an alicorn doesn’t just come with wings. I also got… one of these.” She cupped her crotch, shifting her cock beneath her skirt.

“Wait,” said Sunset, “So all alicorns get one? Because I spent a lot of time with Celestia, and… I mean… I feel like I would have noticed?”

“She keeps it hidden with magic,” said Twilight. “She taught me the spell right after I ascended.”

“Why?” said Aria. He was still nude, and now openly stroking his six-inch cock with one finger. He tilted his head, trying to sneak another peek at Twilight’s dick, but it was once again well-hidden beneath her skirt. “Celestia wouldn’t have anything to be ashamed of. I bet her cock is huge.”

“No comment,” said Twilight. “And some details of alicorn biology aren’t made widely known, because… well, we’re important parts of Equestria’s defenses when it comes under attack. And when someone does attack… the less they know about us, the better.” She pointed a finger at Sunset, then Aria. “So… I guess I’m swearing both of you to secrecy.”

“Yeah, no problem,” said Sunset. “So why do alicorns get dicks, exactly?”

“Oh, you know,” sighed Twilight, “It’s all part of… ‘embodying all aspects’ of ponies. Most ponies think that just means being a unicorn and a pegasus and an earth pony.”

“You’re an earth pony too?” said Aria.

“It’s not as obvious, but yeah,” said Twilight. “A little physically sturdier than I was before, and… I haven’t really tried my hoof at gardening, but I’d probably find it relatively easy. But anyway - it’s the same principle. We embody everything, including being both male and female.”

“Cool,” said Sunset. “You and I have even more in common than I thought. But, uh… how to put this… you don’t seem all that stoked about it?”

“I’m less than completely stoked,” admitted Twilight. “Look, there’s nothing wrong with having a dick, okay? Your body is… awesome.” The breathless way Twilight said it made Sunset smile - it was obvious that she meant the compliment sincerely. “It’s just… when you just get a penis out of the blue, and you have to get used to… different feelings… and you have to keep it a secret from most ponies, too…”

“Yeah, I think I get it,” said Sunset. She nodded, her face taking on a serious expression. “You wanna fuck Aria’s ass?”

“What?!” yelped Twilight.

“It sounds like you don’t like your cock the way you should,” said Sunset. “But you’re going to be real happy with the way it feels when it’s buried between those soft purple cheeks. Have you even fucked anyone with it yet?”

“...No,” Twilight admitted.

Sunsed smiled. “Well, this is an excellent place to start. Trust me, once you bust your nut in Aria’s butt, you are gonna run right back to the royal harems to dip your wick again.”

That struck a chord with Twilight. The royal harem was, by necessity, one of the places where it was known that alicorns were creatures of both sexes, and Celestia had opened its doors to Twilight after her ascension. Mares and stallion were lined up, eager to be the first one to get fucked by the new princess’ cock - but Twilight lost her nerve, and ended the day by blowing her load onto the sheets in the royal guest room. After the sting of that failure, she did feel like she needed a confidence boost - and besides, this wasn’t even her real body. If things got weird, then this basically wouldn’t count.

“Aria?” said Twilight, “You’d be all right with this?”

Aria barked out a laugh. “I don’t think I could have possibly made it clearer that I’m a huge slut, princess. Come on, let’s hit the bedroom.”

Aria turned, showing off his ass to the girls, and sauntered to the bedroom, moving his hips for maximum bounce and jiggle. Twilight sat on the couch for a moment, watching that bubble bounce - but then it finally hit her that that ass was going to be hers. She jumped from her seat and raced forward, swinging her arm to give Aria’s ass a slap.

Aria gasped when he was smacked, and the gasp dissolved into a satisfied moan. “Oh, that’s good,” he whispered, turning towards Twilight and slipping his hand around her waist. “I was worried the princess would go easy on me. But there’s just something about this big round boy ass, isn’t there? It’s beautiful… but when you see it, you just want to abuse it.”

Twilight shuddered with arousal. She was rock-hard, harder than she’d ever been in her life, and Aria’s dirty talk was giving her just what she needed. As they entered the bedroom together, she felt his eager fingers working down her panties, fumbling to get them around her throbbing shaft.

Aria worked Twilight’s panties off just as they got to the bed, and they fell to the floor as Aria hopped onto the bed and dropped to his hands and knees. “All right, Sparkle,” he said, moving his butt up and down hypnotically, “My ass is all yours. Just get me where you want me, get these cheeks right at dick level, and penetrate me.”

Twilight wrapped her fingers around her dick, feeling it twitch in her hands. She felt like she was going to cum then and there, just from the steady stream of dirty talk that Aria was feeding her. Wouldn’t that be humiliating: just nutting all over Aria’s butt, painting that wide, round target with her load. She could picture just how it would look: crisscrossed, creamy lines of spunk dripping over every inch of those jiggling curves. Twilight’s balls weren’t especially big - not much more than average - but they always managed to shoot a big, messy load.

She got a moment of distraction when she felt two hands on her ass, making her jump. “You didn’t think I was going to give you two privacy, did you?” She kneaded Twilight’s butt with her fingers, massaging the bare skin under her skirt. “Hm, I’m used to a bigger, juicier butt,” she said, “But the color’s very nice.”

“Oh, Sunset, uh…” Twilight stammered. “I don’t think I’m ready for… that.”

Sunset laughed. “Don’t worry, princess, I’m not gonna fuck you. I’m just a sucker for butts, and I was taking a moment to admire yours up close.” She paused. “But I’ll remember what you said. ‘Not ready,’ huh? You just let me know when you are.”

Sunset took her hands off Twilight’s ass and strolled to the other side of the bed. Twilight could see now that she was totally nude, having apparently managed to strip herself down on the way to the bathroom. That was an impressively fast job. “So,” said Twilight uncertainly, “Are you just going to watch? Do you need me to, like… say stuff to you? About how I’m fucking your boyfriend?”

“Oh, I’m not just going to watch,” said Sunset, climbing onto the opposite side of the bed. “If Aria’s in the same room as two big girl-dicks, I have a feeling he’s going to want both of them.”

“Oh yeah,” said Aria, licking his lips. “See, this is why our relationship works. Because I love cock and Sunset knows it.” Sunset knelt on the bed, putting her hard orange cock at the level of Aria’s mouth, and Aria licked along its length, up from her ballsack to the tip of her shaft.

Twilight shivered with arousal again, fearful that she would blow her load just from watching. Keeping her breathing under control, she lifted her cock beneath her skirt and brought it to where Aria was poised on the edge of the bed. The tip of her dick touched the crack of Aria’s butt, and Twilight moaned softly as she felt just how soft the femboy’s butt was. Like two domes of warm purple marshmallow.

“Mmm, we have contact,” purred Aria, between licks of his girlfriend’s cock. He was taking time with Sunset’s member, sucking and licking at it like a lollipop, savoring the flavor of her skin and the warm musky precum the tip was beginning to produce. “Get in there, princess… You have no idea how much my ass needs this.”

Twilight slowly worked herself deeper. There was a lot of ground to cover, a deep, wide crack between those big round cheeks. She moved her hips slowly, hotdogging Aria’s ass with gentle motions. “Ohh, you’re just as bad as Sunset,” said Aria. “You can’t just fuck a boy, you gotta tease him til he goes crazy.” He tensed his cheeks, making his crack tighter around Twilight’s dick. “Lube’s by the bed, bee-tee-dubs.”

Twilight reached over and grabbed the bottle of lube, then upturned it over Aria’s ass, letting the warm fluid drizzle over the top of his crack. The two of them worked together to spread the slick lube everywhere it needed to be, making squishy noises as Twilight hotdogged Aria’s booty and Aria clenched his cheeks around Twilight’s cock.

“Come on,” moaned Aria. His voice was slurred - he had no intention of removing his tongue from Sunset’s cock at this point, and had to talk without full tongue mobility. “Come on, just stick it in, don’t torture me.” That was the last thing Aria could say before his hunger for his girlfriend’s cock totally overwhelmed him, and he wrapped his lips around it, making the transition from cock worship to full-on oral.

“Do it, Twilight,” said Sunset, putting her hand on the crown of Aria’s head. “He’s been a good little femboy. Almost totally redeemed. Give him what he needs.” She moaned, grinding her hips into Aria’s face. “Fuck my femmy boyfriend, Twilight!”

Twilight gave in. She found Aria’s pucker, deep within his soft lavender mounds, and poised her slick cock at his entrance. She gripped his hips, sinking her fingers deep into the yielding ass-flesh, and bucked her hips, penetrating his hole. She gasped, feeling the warm walls of his ass surround and embrace her shaft.

Twilight had experimented with her cock before, since it had sprouted, fully formed, at the moment of her ascension. She’d bought toys meant to simulate holes of all kinds, developing a collection of a frankly embarrassing scale, as she’d delayed the task of actually fucking someone else. Some of them had been enchanted to simulate the warmth and the movement of a living body, but none of them compared to what she felt when she inserted herself into Aria’s asshole.

Fireworks. Her human body, unfamiliar as it was, was lighting up with ecstasy, and she hadn’t even really started to fuck Aria’s ass. Tentatively, she pushed herself deeper, letting the lubed-up boy butt swallow up more and more of her. Aria was moaning around Sunset’s shaft, and the sound inspired her to go balls-deep, sinking every last inch of her foot-long cock into Aria’s backdoor.

Sunset’s ears perked up when she heard Aria start to moan. “Oh, you’re in, aren’t you, Twilight?” she said, ruffling Aria’s hair and shooting Twilight a sultry look across his spitroasted body. “I know what makes this slut moan. Keep it up. Fuck him. He wants it hard. Isn’t that right, gorgeous?” Aria mumbled something that could have been agreement.

“Yeah,” gasped Twilight, “I’m gonna fuck him. Oh, Celestia, his ass feels incredible around my cock…”

“Yeah, he’s made to be fucked,” said Sunset. “He makes himself so beautiful, you just can’t resist him, can you? That big round ass, that lovely mouth… You see this little slut boy, and you just have to put your cock somewhere.”

Twilight started to pump her hips, making long strokes in and out of his ass. “Oh, it’s good, it’s so good… I can’t believe a boy has a butt this big and tight…”

She wrapped her hands around his hips, searching for a grip that would let her go harder. She pumped herself faster, delighting in the rising, desperate tone of Aria’s muffled moans as she pounded him again and again. His ass quaked like jelly as Twilight pounded away at his body, slapping his cheeks with her pelvis each time she went balls-deep in him. Twilight looked up at Sunset, whose face was flushed but wearing a confident smile. Her body was shaking too; the mattress underneath her and Aria was shaking from the power of Twilight’s thrusts, and the motion was more than enough to make her tits jiggle.

It was Aria’s body that had driven Twilight wild with lust, but Sunset Shimmer was beautiful too: tall and powerful, with a cock that dwarfed even Twilight’s. She couldn’t help but notice that Sunset had let herself go just a bit: there was still power in her limbs, but her toned tummy had given way to an adorable little pudge. And her tits - they weren’t huge, but they were big enough that they had some bounce to them. Watching this beautiful woman get her dick sucked would be a damn good show even if Twilight wasn’t a foot deep in Aria’s luxurious ass.

The walls of Aria’s ass tightened around her, throbbing with involuntary movement, and his body started to shake on its own. Twilight felt a series of contractions squeezing her cock as it glided in and out, and when they ended, she titled her body slightly to see Aria’s load staining the bedsheets. Not much of a cumshot, compared to the loads Twilight was now used to producing, but it felt like it had been an intense experience for the femboy.

“Hey Sunset,” gasped Twilight, “I just made your boyfriend cum.”

“Awesome,” said Sunset. “I’m impressed that you managed to hold out this long. Mmmh… I was half expecting you to blow your load as soon as you got inside him.” Aria’s body had slackened, drained by his climax, but he was still slurping Sunset’s cock with just as much enthusiasm as before. “Shit, Twilight, he’s gonna make me cum soon… It’d be pretty sick if we came together, but, like… no pressure…”

Twilight rose to the challenge, pumping her hips faster. She could see the finish line now, and she was sprinting towards it, trying to push herself past the point of no return. No luxuriating in this soft ass or admiring Sunset’s body… all she cared about was he building climax, the tightening in her balls and the sensation rising in her shaft. “Sunset!” she gasped, suddenly gripped by panic. “Should I pull out, or…”

“Hell no!” said Sunset, almost shouting. “Nut in his ass, princess!”

Twilight hilted herself in Aria’s ass, slapping his cheeks with her swinging nuts, feeling her body shake as climax shot up the length of her cock and exploded inside the boy’s gorgeous ass. The inner walls swelled with Twilight’s cream, each throb of her cock sending another generous payload deep inside him. By the third pump, Aria’s overstuffed ass was leaking with royal seed, dripping hot princess spunk onto the sheets.

Halfway through Twilight’s orgasm, Sunset joined her. Her fourteen-inch cum cannon fired its load into the back of Aria’s throat and onto his tongue, and he swallowed as fast as he could, eager to have his belly filled from both ends. His mouth fared better than his ass; only a little cum crept out from the corners of his painted lips, but his ass was dripping cum all over the sheets, almost totally failing to contain Twilight Sparkle’s load.

Twilight felt her orgasm coming to an end, her cock erupting with its last, comparatively feeble cumshots, and she staggered back, weak-kneed. She looked down at Aria’s ass as she pulled out, watching the cum drip from between the round purple cheeks, smiling peacefully at her handiwork. She let herself fall forward onto the bed, too tired to stay standing. Being on two legs still didn’t feel totally natural, and after the best orgasm of her life, she felt like she deserved a break from it.

Aria, his ass no longer held up by Twilight’s cock, slumped down onto the bed. Sunset’s cock slipped out of his mouth, smearing his face with the lst of her load as he fell away from it. And Sunset, now the only one remaining upright, flopped onto the bed, so that her head was right next to Twilight’s. Time for some post-coital girl talk.

“So that’s why having a cock is awesome,” said Sunset. “Let me know when you get a femmy stallion to fuck, over on your side of the mirror.”

“I will,” said Twilight. “At very least, I’m going to take a trip to the royal harem very soon.”

“You’re not leaving, are you?” said Aria, laying a hand on Twilight’s thigh. “You’ve got to at least stay for the weekend. Next time you and Sunset can switch places. I wanna give that royal cock a tongue-bath…”

“Wow,” said Twilight. “Not to brag, but I gave you a pretty serious pounding. You’re already thinking about next time?”

“Oh, Aria’s always thinking about the next time he’s going to get fucked,” said Sunset.

“Well, I’ll stick around,” said Twilight. “I was going to ask if your couch folded out, but… I hope you won’t mind if I join you two in bed.”
