"Oh, crap," whispered Zoe, looking down at her tiny classmate and wincing. "That's my roommate!"

"C'mon, dude!" The voice from the hallway sounded impatient. "I forgot my keys."

"Uh, j-just a sec!" Turning back to Max, the bespectacled freshman blushed. "I'm really sorry, dude, but I think you gotta go back in my pants for a sec."

Still shaking off his brief imprisonment in Zoe's ass, Max crossed his arms. "You don't trust your roommate?"

"I... not really?" Zoe shrugged. "Not with this. She's not big on guys... like, at all. I dunno if she'd report you, but..."

"I-isn't there somewhere else you could hide me? Like, a drawer or something?"

"I..." Zoe hesitated.

"'Zo!" This time, Zoe's roommate punctuated her request with several knocks. "You jacking off in there again or something? C'mon!"

Zoe blushed. "Freaking gimme a second, okay?" Finding herself out of time and options, she mouthed another "sorry" to Max before scooping him up and shoving him back down into her underwear.

"Wait," said Max, "Zoe, what if -MMMMPPPHHH!!!"

"Sorry!" she whispered, hiking her pants back over her hips and sealing her shrunken classmate into her rump. Then, once she was absolutely certain he was secure, she stepped over to unlock the door. "Sam! Hi!"

"Took you long enough," said Samara, shaking her head and pushing past Zoe into the room. "What were you doing?"

At 5'7" and 190 lbs, the Indian-American freshman was slightly bigger than her roommate, with long, straight black hair, thick black eyebrows, smooth brown skin and plenty of curves in all the right places. Right now, she looked like she was just getting back from a long night of either studying or fucking—though with Sam, it was always hard to tell which. Wearing her usual uniform of a tight black sweater-vest over a white button-up shirt, oversized black jeans and black boots, with piercings on her lip, nose, and eyebrow and a thick layer of black eyeliner, she definitely looked the part of a young woman who'd had the rare honor of being courted by both the nerds of House Minerva and the goths of House Juno. 

"N-nothing!" Zoe stammered, blushing again.

Samara smiled. "So you *were* jacking off, huh?"

While this interaction was happening, Max found himself slipping deeper and deeper into Zoe's ass. Reunited with the overwhelming pressure of her huge, soft buttocks and the smell of her sweaty, stinky underwear, he was almost completely unable to breathe. Already, this was far and away the single weirdest day of his life.

Trying not to give anything away to her roommate, his blue-haired captor forced a scoff. "Sam-"

"Look," said Samara, "all I'm saying is, next time you're gonna do that, let me know. Maybe we can help each other out."

 While Zoe and Sam had a lot in common, namely their shared love of Japanese video games and anime, their sex lives couldn't have been more different. In many ways, their dynamic wasn't too dissimilar from Max and his roommate Zeke. The Indian-American lesbian had already "sexiled" her roommate to the common room several times over the last few weeks, and while Zoe wasn't one to cast judgement on anyone's preferences, she wasn't a huge fan of sleeping on the couch. All the advances that Sam kept making on her didn't help, either.

"Sam!" Blushing furiously, the blue-haired freshman pushed her oversized glasses up the bridge of her nose, trying to ignore the tiny man struggling between her cheeks. "How many times do we have to go through this? We're roommates! I mean... what part of you thinks that would be a good idea?"

Samara shrugged. "The part of me that likes getting off? And the part of me that knows you're not getting any."

As the two roommates continued their conversation, Max was too busy trying not to asphyxiate to hear much of what was being said. At this point, he was just a few short inches away from his former bio classmate's huge, unwashed asshole—now roughly the size of a manhole to his shrunken form. Then, watching the muscles around the ring begin to twitch, the three-inch-tall 18-year-old realized that his situation was about to get even worse.

PFFFOOOOOOOOOTTTTTTT

For Zoe, the fart she'd just cut in her tiny classmate's face was relatively small—but for Max, it was an all-out assault on the senses, washing over his entire body like a massive, sulfuric explosion. Worse, with no way out of the Brazilian nerd's big, soft butt, he had no choice but to breathe it all in. After just a few desperate lungfuls, he felt like he was on the verge of blacking out again. 

Sniffing the air, Samara wrinkled her nose and laughed. "Fuck, dude! That reeks!"

"You're one to talk," said Zoe, crossing her arms. "At least I'm not lactose intolerant."

"Smells like you are," her roommate teased.

Down in Zoe's butt, Max felt like an insignificant insect caught between two bickering goddesses. With his face pressed right against the deepest, darkest, smelliest part of his classmate's big, curvy rump, all he could do was hope that she had a plan to get her roommate out of her hair, and fast.

"Yeah, yeah, yeah," said Zoe, still completely cognizant of the tiny man on the verge of getting sucked up into her rectum. "What'd you even come back here for?"
