"Nice digs," said Aria, following Sunset through the front door to her apartment. "How's a refugee from another world afford an apartment with no job?" Seeing Sunset remove her boots, he took his own boots off and left them by the door.

"Some things are common in Equestria and pretty rare in this world," said Sunset. "Once I figured that out, I snuck back through the magic mirror and brought through some gems. Got a real good price. Leased an apartment, invested some of it..." She closed the door behind her.

"Ugh, sounds like a pain in the ass," said Aria, flopping onto Sunset's soft blue couch. "The girls and I just used mind control to make people give us stuff. We're startin' to run out, though."

"Well, maybe I can help you out," said Sunset. She dropped onto the couch beside Aria and put her arm around his shoulder. "But what'll I get in return?"

"Back at school you were talking like you were doing me a favor," said Aria, smirking. "But I like this version better. Like you said, boys like me are hard to find."

"Yeah," said Sunset. Her hand went lower and crept under Aria's top, and her fingers groped his soft tummy and teased his belly button. "But girls like me aren't easy to find either. We're both pretty fucking special." She let her fingers creep into Aria's tight purple shorts, nimbly undoing his silver-star belt buckle on the way down. "Let's see what you have down there, girly boy."

Aria braced himself on the couch as Sunset's fingers found his cock. It was tucked back, and its position prevented it from getting fully hard - but once Sunset unzipped his pants and freed Aria's purple cock from his pants, it grew erect instantly. "Hm, what is that, six inches?" said Sunset, running her fingers up and down the silky shaft. "Not bad for a femboy. Not that it compares to the thick girlcock I've got waiting for you..."

Sunset's fingers worked Aria's balls out from his tight underwear - a pair of lavender panties just a bit lighter than his skin tone - and gently stroked the smooth, hairless ballsack. "Mmm, you're adorable," Sunset murmured, "Smooth and so... petite. You like your human body, Aria? Were you happy when you came through the mirror all slim and pretty with big round hips?"

"Well, when I came through the mirror, it was like right after Beardo the Wizard defeated and banished us. So no, I didn't feel great." He was having a hard time sounding annoyed while his dick was being softly stroked - and it only got harder when Sunset leaned her soft cheek into the crown of his head, nuzzling him and smelling the fragrant, fruity shampoo he'd worked into his long multicolored locks. "But yeah, I like the way I look. Most people think I'm a girl, which is fine by me. And this big butt is lot of fun..." He shifted his hips, pulling himself onto Sunset's spacious lap, grinding his soft cheeks into the big, hard bulge at the intersection of her thighs. The bulge, still trapped within Sunset's panties, grew harder and dug its way between Aria's cheeks.

"How about you?" said Aria. "You like the body you ended up with? All big-dicked and... Amazonian?"

"Oh, I've always had a cock," said Sunset, flexing her bulge under Aria's buttcrack. "And it's just as big here as it was back in Equestria. Turns out a fourteen-inch cock is pretty fuckin' huge by human standards." She ran her palm over the head of Aria's cock, using her thumb to milk out precum and slick up the skin of her hand. "As for being seven feet tall... that took some getting used to, but you know what? It's fun." She leaned her head down, putting her mouth next to Aria's ear and speaking in a breathy whisper. "I like being bigger than boys."

Sunset, her hand slicked with Aria's pre, worked her hand up and down the slim purple shaft. "You know Flash Sentry, right? Handsome, popular... I'm sure you noticed him." She darted her tongue into Aria's ear, making his body shudder and his cock twitch. "I was awful to Flash back then... but you know what? He learned to love sucking my long, fat cock... and having his tight ass fucked..."

"To be honest," said Sunset, "I'm a pretty big fan of sucking dick too." She took her hand off Aria's shaft - making him whimper pitifully - and lifted his slender body up easily in her powerful arms. Sunset Shimmer's human body was naturally athletic, and muscle built quickly on her Amazonian frame - to her, Aria Blaze was almost weightless. She turned his body around and raised his crotch up to the level of her face. Aria gripped the back of the couch, steadying himself as Sunset brought his wide hips closer to her face.

Aria groaned as Sunset's lips kissed the tip of his cock, and his hips bucked involuntarily as her tongue flicked out to taste his pre. Her lips parted and took his cock deeper, her slick, powerful tongue running along the underside of his shaft. With the immense strength in her arms, she moved Aria's body back and forth, moving his cock in and out of her mouth with each motion. Sunset's tongue moved along Aria's shaft hungrily, tasting his pre and the skin of his cock. She took him deeper, bringing his hairless balls into her mouth and caressing them with nimble motions of her tongue.

"Oh shit," said Aria, "I'm close, I'm gonna cum..." At those words, Sunset slowed the pace of the blowjob, and Aria whined. "No, come on," he said, "lemme cum, I gotta cum..."

Sunset popped Aria's cock out of her mouth and lowered his body into her arms, cradling him as she stood from the bed. "Oh, you'll cum," she said, "But I think it's time for a change of venue."

Sunset's bedroom was a calming off-white, with neat, clutter-free surfaces and colorful paintings lining the walls. Although Aria didn't recognize the structures in the paintings, something about them seemed distinctly Equestrian. A little reminder of home.

Aria expected to be thrown into the bed, but Sunset set him down on the carpet and sat herself on the bed. She plugged her cell phone into a dock with built-in speakers and tapped at the screen for a bit - and then a pounding beat filled the room. "All right," said Sunset. "You can't sing so well, anymore, but you're still a performer. Strip for me, girly boy."

Aria sneered. He'd been so close to coming, and now he was standing at the foot of Sunset's bed with his dick hanging out, being ordered to strip. He thought about protesting, but just as he opened his mouth, he caught a glimpse of Sunset's bulge, lifting up her short skirt. Fourteen inches, he thought. He had to know what it felt like to have that monster in his ass.

Not to mention, the beat of the song was really speaking to him. He was still a siren, after all - a creature whose soul was muscial and magical. Even though this world - and the Rainbooms - had stripped away his power, music was still deep inside him. Giving in to the music, he clasped his arms behind his head and began to wiggle his hips, making his exposed dick shake with the rhythmic motion.

Sunset smiled and leaned back on the bed as Aria started to dance. The bands on his arms came off first, one by one, and he tossed them softly onto the bed around Sunset. Sunset reached her hand under her shirt, unhooked her bra, and began to grope herself, massaging her breasts and running her fingers around the stiff nipples.

Aria started to bounce his hips, turning himself around to jiggle his bubble butt in Sunset's face as he stripped away his cutoff green jacket. His white t-shirt followed, baring his chest. It was obvious now that he was no girl; he wasn't simply flat-chested as Fluttershy had assumed. He was a beautifully slim boy, with smooth lavender skin. Sunset's dick throbbed in her panties as Aria ran his fingers over his bare torso, tracing a path down his skin to his hairless crotch. His dick was still exposed, poking out from his unzipped fly, and he grabbed it in one hand, stroking himself as he gyrated his wide hips.

Sunset felt her cock throb and her heart race as she watched the slender femboy perform for her. Aria's body was just perfect - so lithe, so smooth, so femmy. His delicate blush and dark purple eyeshadow was flawlessly applied; he knew his way around makeup better than Sunset did. Flash Sentry had been handsome and athletic, but Aria, small and slim and feminine, was Sunset Shimmer's ideal boy.

Aria slipped his tight purple pants down to his ankles, taking his panties down with them, and turned around to show off his bare booty. He bounced his hips to the beat, making his ass shake, kicking the rumpled pants off of his ankles as he backed his butt up towards Sunset. The strip show became a lap dance as Aria sank his big, soft ass onto Sunset's lap. Her throbbing cock dug into his crack as he bounced his smooth, curvy butt against her thighs.

Sunset panted and moaned as Aria massaged her bulge with his butt. Her cock was straining powerfully against her sturdy panties, the thick, meaty shaft painfully fighting against the fabric. She'd never been this horny before, never in her life -

Sunset's cock burst through her panties, ripping the seams apart and slapping against Aria's cheeks. The sound of the fabric ripping was loud, and the impact of her fat shaft against Aria's butt was so hard that it made him jump. "Holy shit," said Aria, grinding his ass into her now-exposed cock, "Did you just bust open your panties?"

"Yeah," panted Sunset. "Would you believe that's never happened before?"

"Mmm, it's going to happen all the time now, I bet," said Aria, rubbing his asscrack against Sunset's upright shaft. "You're gonna be in class, thinking about how my big round ass felt around your cock... and your meaty monster is gonna rip those panties open right in front of everyone." He leaned down, raising his ass up to rub the tip of her shaft. "You're gonna get addicted to my body once you bust a nut in this butt."

"So... full of yourself," said Sunset. "You remind me of the old bitchy me."

"Hmph," scoffed Aria. "If you were turned off by bitchy boys, we wouldn't have gotten this far. You gonna fuck me or what?"

"Oh, I'm gonna fuck you all right," said Sunset. She leaned back and grabbed a small bottle of lube from her bedside table, then squeezed a generous dose onto her cock. Aria felt the slick fluid flowing over the shaft he was pleasuring, and he used his ass to spread it over Sunset's cock and slick up his butthole. When Sunset put the bottle of lube back, she changed the song playing on her phone, starting up another track with an intense, pounding beat.

As soon as Aria's pucker was lubed up, he felt Sunset grab his arms. With her Amazonian strength, she lifted him up and threw him onto the bed. He'd been facing away from Sunset for a while, but now, lying on his back, he was looking up at her, seeing how her nostrils flared and her breasts heaved as she drew deep breaths. She was powerfully horny, staring down at Aria's body with clear intent to conquer it. It occurred to Aria only now, at the last possible moment, that Sunset Shimmer was frightening. She was huge, her cock was gigantic, and Aria was all but defenseless. What must it have been like to be her boyfriend back when she was bad? Staring down that beast of a cock, knowing it was going inside you...

Well, Aria was just lucky that Sunset wasn't bad anymore. And that he wanted that cock so bad.

Sunset lifted Aria's legs in the air and poised his ass at the edge of the bed. She bent her knees slightly, putting her dick at the perfect height to prod at Aria's tight purple pucker. "Mmm, I bet this butt is tight," she said, rubbing her slick tip against his entrance. "You get this ass fucked much, girly boy?"

"No," said Aria, gritting his teeth, preparing for a huge insertion. "Mostly I just play around with Adagio and Sonata. It's been a long time since I got fucked..."

"And you decided you just had to get a fourteen-inch cock in your ass?" chuckled Sunset. "Well, maybe this can be lesson one in not being a villain. You need something to make you... humble."

That was all the warning Aria got before Sunset's cockhead rammed into his hole. He yelped, then groaned, clutching at the bedsheets as he felt his asshole stretch around the inhumanly thick shaft. Sunset, still clutching his legs, pulled him towards her as she thrust her hips forward, easing her cock into him. He squirmed on the bed, helplessly trying to kick his legs as Sunset held them fast.

"Ooh, my girly boy's sounding humble already," said Sunset. "Starting to think your butt isn't up to the challenge?" She reached down and caressed his face with gentle fingers, even as her brutally thick cock spread open his asshole. "Well, this can be lesson two. When you have people who care about you, you can do anything." She patted his face gently, then lifted his hand and grabbed his leg again. "And I do care about you, Aria. I want you to enjoy this. You wanted your big boy butt to get fucked by a big fat girlcock, and I'm going to make sure you love it."

"Urgh..." groaned Aria, "You bought into a lot of sappy shit when you stopped being evil..."

"Stick with me, Aria Blaze," said Sunset, a smirk breaking out on her face. "I'll teach you all sorts of sappy shit. Come by my apartment to get your ass fucked, and I'll give you a primer on being a boring little goody-two-shoes." She eased herself deeper into Aria, making agonizingly slow progress into his ass - and finally she was balls deep inside him, every inch of her cock spearing his tight hole open. Her hips bumped against Aria's soft, round rump, and she reached a hand down to caress its perfect curve.

"You're beautiful, Aria Blaze," she said, staring into his eyes. "You're gorgeous girly boy. You know that?"

"Of course I know it," said Aria, although it was hard to sound properly haughty with a fourteen-inch cock in his ass.

"Hm, back to lesson one," said Sunset. "Gotta make you humble." Her cock pulled back, making Aria gasp sharply. Having his ass emptied was almost as much of a shock as having it filled. But it wasn't empty for long - Sunset slammed herself back in, hilting herself in Aria's ass with such speed that her balls spanked his ass with their hefty, pendulous weight. She pulled back again, then rammed herself into Aria, giving him almost no time to recover from the last thrust. Every movement of Sunset's cock against his stretched-wide walls sent shockwaves of sensation through his slender body - and not all of it was pleasure. Not nearly. Sunset's cock was an invader, a big one, and his body was panicking, making him twitch and thrash on the bed. He wanted that cock, but it was just too much...

"Ooh, my girly boy's having a hard time," cooed Sunset. There was sympathy in her voice, but she didn't slow the pace of her fucking. "You're gonna be just fine," she said. "Your body is gonna relax and you're gonna love having that thick booty filled up with girlcock." Aria didn't respond - his eyes were shut tight, his face flushed, and his teeth gritted as he squirmed on the bed. "Hm," said Sunset, "Maybe this'll help."

Sunset dug her fingers underneath Aria's ass and lifted him off the bed. Even as he struggled with the overwhelming sensation of Sunset's cock in his ass, he couldn't help but marvel again at her strength. Keeping one hand under Aria's butt, she wrapped the other arm around his body, holding him in a powerful - but gentle - embrace. He was upright now, held against Sunset's body, his ass still impaled on her cock. Aria wrapped his arms around her torso, running his fingers along the muscles of her back and the ridges of her spine. He buried his face in her cleavage, smelling her sweet skin. He felt the beat of her heart through her chest.

And it did help. Aria felt his whole body relax - and most importantly, his ass relaxed. Sunset noticed right away, and she made the most of the opportunity. She lifted Aria's body up - easily, without effort, just like always - and then slammed him back down onto her cock. His ass tensed as he was filled up, but it relaxed again, the muscles of his ass pulsing in a quick rhythm.

"Oh yeah," said Sunset. "This is gonna work." She lifted him up and slammed him down again, quickly building herself up to a powerful rhythm. Her phone was still playing a pulse-pounding beat through the speakers in its dock, and she worked her thrusts up to match its speed. Aria shuddered in her embrace, feeling his ass pulse faster and faster. His balls tightened, and each time Sunset's shaft slid against his prostate, it lit up his whole body, making him feel like he was going to explode-

And then he did. His cock, pinned up against Sunset's toned belly, shot its first jet of cum between their embracing bodies. His cock spurted again and again, the orgasm going on longer that he could have imagined was possible. Every time his body slammed down onto Sunset's fourteen-inch dick, his cock shot more and more of its seemingly inexhaustible load.

But eventually it ended, and the sticky load dripped over Sunset's six-pack abs and down her thighs. "Mmm," said Sunset, briefly slowing the pace of her fucking, "My sweet girly boy shot a nice big load... got me all messy and sticky..." She picked up the pace again, thrusting her hips into him with each motion. "Hope you're ready for this fat girlcock to nut in that big bubble butt."

"Yeah," said Aria, gasping and leaning his head into Sunset's tits. "Cum in my ass. Fill me up til my ass is dripping with that hot load..."

"Yeah," growled Sunset. "Yeah, I'm gonna cum for ya. Cum in that big... sexy... boy butt..." She fell forward onto the bed, pinning down Aria underneath her massive body. She fucked him faster, making quick, shallow thrusts inside his ass, panting and gasping and sweating. The climax built in her core and spread though her limbs, making her quiver from head to toe - and her body, powerful as it was, could only take so much sensation before something had to blow. And when she came, it was tremendous, firing hot, thick jets of spunk deep into Aria Blaze's overstuffed ass. Before she was halfway through her orgasm, her cum was spilling out of Aria's butthole, thick white cream pouring out of him in fitful spurts. Aria's body shook with each throbbing pulse of Sunset's thick, spasming cock, until her body wore itself out and her cock shot the last of its load.

Sunset's body went limp, its immense weight settling on Aria and pinning him against the bed. She lazily slid herself out of his ass with a wet pop, making more of her cum leak out of his overstuffed bubble butt. She rolled onto her side, taking him along with her, and spooned his slender body, holding him tight in her embrace. Aria's panting breaths settled into a gentle, slow rhythm, and he drifted off to sleep.

After a short nap and a quick shower, Aria was dressed and on his way out the door. "Don't be a stranger," said Sunset Shimmer, smiling warmly. "I've been in your position, Aria, and it would have gone badly if I didn't have friends to help me."

"Don't talk to me like I'm helpless," said Aria, his sour demeanor back in full force. "If you want me to come back so you can fuck my ass again, just say so."

Sunset sighed. "Whatever brings you back is fine with me," she said. "Just don't let your pride get in your way, okay?"

"Yeah," said Aria, rolling his eyes. "Lecturing me is really gonna make me want to come back."

Aria turned on his heel and set off down the hall, making sure to shake his ass enticingly on the way out. He was five blocks away before he realized he'd left his high school transcript - the whole reason he'd come to Canterlot High today - back in Sunset's apartment. He stopped, grumbling to himself - then smiled. If his transcript was back at Sunset's place, then he'd have to go back there. He set off down the sidewalk with a spring in his step, his bubble butt jiggling with every step.
