"Really?" said Sunset Shimmer, raising an eyebrow. "None of you noticed?"

The rest of the girls around the lunch table shook their heads. "I really don't know what you mean, darling," said Rarity.

"I think the rest of us were more focused on playing our instruments," said Rainbow Dash. "I dunno, maybe Twilight noticed?"

"Twilight ain't ever been human for more'n a few days at a time," said Applejack. "I don't reckon she's gonna notice if some girl is secretly a boy."

"I know what I saw," said Sunset, shifting in her seat. She could never really get comfortable in the cafeteria's chairs - or any chairs at Canterlot High, really. They just weren't designed to comfortably accommodate a girl of Sunset's size. She wasn't fat - from from it - she was big. Sunset hadn't been an especially big mare back in Equestria, but apparently the magic mirror had decided that her human form would be seven-foot-one, making her the biggest girl - the biggest person - in Canterlot High. Her Amazonian height had been an advantage back when she was ruling the school through intimidation, but now that she was trying to be a normal girl, she was a lot more aware of the ways it made her stand out.

"Um... Aria really looked like a girl to me," said Fluttershy. "I guess she didn't have much of a... bust... but her face was really pretty..." Her butter-yellow face reddened with a deep blush. Fluttershy was a great admirer of the female form (which is to say, she was gay as all hell), but she was shy about admitting when she'd been staring. "And her, uh... bottom was... well..."

"The term you're looking for is 'bubble butt,'" said Sunset Shimmer. Fluttershy sank in her seat, growing more embarrassed. "And yeah, it sure was. I'm telling you, though, he was a boy. Just a really girly boy."

Sunset shifted her legs. Talking about the body of Aria Blaze was getting her excited, and getting excited was... inconvenient. Sunset Shimmer wore the stretchiest, sturdiest panties she could find, but every time her cock started to get hard, she felt certain that it was going to bust through the fabric and lift up her skirt. And since she was packing fourteen inches down there, she'd really be putting on a show if she had an uncontained boner. Her short skirt wouldn't do a thing to conceal it... it'd just be standing out in the open, where everyone could see it...

Sunset sighed. Thinking about exposing herself to the student body was not helping her keep her cock down. The other girls, anticipating the bell for next period, picked up their trays and started towards the door - then stopped when they saw that Sunset was still seated. "Are you coming?" asked Rainbow Dash.

"Uh, I'm having... girl problems," said Sunset, biting her lip.

"Oooohhhh," said Pinkie Pie, nodding her head. Then, in a hissing whisper to Rainbow Dash, she said , "That means her dick is hard!"

"All right," said Rarity, as the girls departed, "We'll see you in class, dear."

Sunset did her best to think unsexy thoughts as the end of lunch period approached, somewhat mortified that she'd been forced to admit to her friends that she had a boner. To their credit, the girls had been really understanding when she'd revealed that she had a cock. Pinkie Pie had even asked to see it, a request she'd eventually granted.

Sunset's "third leg" wasn't exactly a secret - Flash Sentry certainly knew about it - but she did her best to keep it hidden for reasons of decency. Back when she was queen of the school, a few students had found out about it and tried to use it to blackmail her. The cheerleader in charge of that little operation had learned the hard way that Sunset Shimmer was not ashamed of her cock - by having her face shoved into Sunset's crotch.

Sunset still felt a little bad about that. Still, they had been trying to blackmail her.

Sunset's cock didn't like going down after it started to get hard - she'd had to jerk herself off in the girls' room more than a few times - but she was starting to feel it soften, and she started to stand up, when she saw... him.

No way, thought Sunset. What is Aria Blaze doing back here?

Aria walked through the nearly-empty cafeteria, his eyes narrowed in annoyance. He caught Sunset staring and shot her a sour look, then strolled haughtily out of the room, his bubble butt bouncing with every step. Sunset felt herself getting hard again, but she couldn't look away from that astounding ass - the jiggling cheeks were hypnotic.

As Aria left the room, Sunset grumbled and stood up, subtly adjusting the bulge under her skirt. Boner or no boner, she had to find out what Aria was doing here.


Sunset strode down the hallway, passing rows of whispering students huddled against the lockers. She picked up a few of the whispers - unsurprisingly, they were all talking about Aria, who none of them had probably ever expected to see again. Aria wasn't hard to find - his tightly-wrapped bubble butt was like a beacon to Sunset's lusting eyes. She caught up to him quickly, and when he heard her footsteps approaching he turned around with a heavy sigh.

"What do you want, Stretch?" said Aria, putting his hand on one wide, cocked hip. His long ponytails flipped as he turned his head up to look Sunset in the eye, and Sunset fought back a blush. Aria was just so fucking cute...

"I want to know what a dangerous magical threat is doing back in Canterlot High," said Sunset, trying to keep her voice stern. Aria might have been cute, but he was still a villain.

"Well, right at this moment," said Aria, grinning cruelly, "She's interrogating me by the water fountains. I don't know why she thinks she's still welcome at Canterlot High, after she terrorized everyone at the school and turned into a demon or something..." he shrugged. "But there's your answer."

Sunset rolled her eyes. "I'm actually a lot less tormented by my past these days. Nice try, though. What are you doing here?"

"If you must know," said Aria, "The girls and I are trying to figure out how to, like, not be homeless and stuff now that we don't have mind-affecting magic. And since we actually did take some classes here, we're trying to get our transcripts."

Sunset scoffed. "So you want us all to believe you come in peace?"

"You're the last person who should be skeptical of our motives," said Aria. "If 'bad guys' are all rotten to the core, then what's your secret plan to gain the school's trust and then win back the magical power you lost? You show me yours, I'll show you mine."

Sunset recoiled, shifting her legs to try and reduce the visibility of her dick. Aria laughed. "Relax, Sunset," said Aria. "That thing's nothing to be ashamed of."

Sunset looked around, scanning the area for prying ears. Luckily, most students were giving the two former villains a wide berth. "So you noticed, huh?" she said.

"Most people don't?" chuckled Aria. "The students here are dumber than they look if they didn't notice that the monster in their midst has a monster under her skirt."

"Yeah, it takes a keen mind like yours to stare at a girl's crotch," said Sunset. "For what it's worth, I know your secret too."

"Secret?" said Aria, raising an eyebrow.

"I know you're a boy, Aria."

"That's not really a 'secret,' said Aria, frowning darkly. "It's more of a... 'none of your damn business.'"

Hmm, that's too bad," said Sunset, taking a step towards Aria. "Boys like you are hard to find."

Aria leaned back, suddenly seeming to be genuinely intimidated by Sunset Shimmer. Standing at five foot ten, "Okay, hang on," he said, "are you grilling me or flirting with me?"

"Well, I wasn't sure at first," said Sunset, leaning forward to loom over Aria, "But back when we were enemies, I was watching you and you were watching me..." she arched her back, thrusting her tits out at Aria. "If you're really not a bad guy anymore, then maybe the two of us can... make peace with each other. And if you want to be reformed, I can take you under my wing..."

"Not sure Adagio would like that," said Aria. But there was something more that reluctance in his voice. He sounded intrigued, as though Adagio's disapproval was something he sought.

"Where did following Adagio ever get you?" asked Sunset. "Kicked out of Equestria, beaten by the Rainbooms... if you're going to get bossed around by a girl, it might as well be, you know..."

"Might as well be one with a huge cock?"

Sunset laughed. "Well, I was going to say 'one with better judgment,' but now that you mention it... there are several things I can give you that Adagio can't."

"Maybe I don't want to be bossed around by anyone anymore," said Aria. "Maybe I'm my own man now."

"Your own man?" repeated Sunset. "With those ponytails? That bratty, pouty voice? And those hips? The word you're looking for is 'femboy.'" She turned away, pointing her toned ass at Aria, and looked at him over her shoulder. "Tell you what. If you want to have some fun, meet me at the statue outside of school at the end of the day."

"Yeah, I'm sure you're loads of fun," said Aria, and he set off down the hall. His tone had been as disdainful as always, but his ass wiggled as he walked away, in a way that had to be deliberate. He knew what he had, and he really knew how to shake it.

The bell rang, and Sunset headed off to class. Her cock was straining against her undies, threatening to tear open the seams, but she resisted the urge to run and jerk herself off in the girls' room. She didn't want to waste a single drop of cum, just in case Aria decided to show his face later today.


"Well, look who showed up," said Sunset. Aria was there, leaning against the monument that held the secret portal to Equestria, as Sunset pushed through the front doors of Canterlot High. He was tapping disinterestedly at his phone and holding a handful of papers in his other hand - apparently he'd gotten his transcript without too much drama.

At the sound of Sunset's voice, he looked up from his phone. "I wasn't waiting around for you, Baconater," he said, trying to look bored. "It took me a while to get this-" he held up the papers in his hand, "and I was just leaving."

"Oh, of course," said Sunset, smiling wryly. "Right out of the tsundere playbook. You weren't waiting for me, you just happen to be hanging out in the exact spot you knew the big-dicked girl was going to show up."

"Yeah, keep telling yourself that," said Aria. "Nothing I like more than having my ass ogled by a girl who loves talking about her penis."

Sunset crossed the distance to Aria and slammed her hands into the monument on either side of Aria's head, pinning him against the mirror-polished base of the structure. She loomed close over him, leaning her tits into his face. He turned his head, trying to look disinterested, but Sunset saw his nostrils flare as he drew a deep breath, taking in the scent of her skin.

"You're real good at being sarcastic, huh, Aria," said Sunset. "Maybe so good at it that you don't know how to ask for something you want." Aria didn't say anything. "Lucky for you, I know what you want." She brought her hips forward, brushing her bulge against Aria's crotch. "Maybe I know it better than you do. I definitely know what you want better than Adagio does. So why don't we go back to my place... and let me give it to you."

Aria was breathing heavy, keeping his eyes down to avoid Sunset's piercing gaze. But the only other place he could look was into Sunset's thrust-out tits, deep into the warm, welcoming darkness of her cleavage. He kept his dick tucked back, which made erections an uncomfortable affair - but there was no avoiding it now. "You sure know how to romance a guy," he said bitterly. "Sure, take me to your place."

Sunset leaned back and smiled. "See, that wasn't so bad," she said.
