"'Morning, Blaise!" 

"S-sheila?" Staring up at the voluptuous Brazilian MILF in your doorway, you weren't sure how to feel. Of all the people to barge into your dorm room this morning, you certainly hadn't been expecting your friend Lillian's mom. Not that you were upset; just confused. Based on the way she was dressed — her sun-kissed brown curves barely constrained by a pair of yellow booty shorts, a tight green t-shirt and flip flops, with her frizzy black hair up in a headband — and the giant duffel bag in her hands, she almost looked like she was moving in. "Morning... what are you doing here?"

"What does it look like, sweetie?" Without waiting for permission to enter, the mature amazon sauntered into your room and hip-checked the door shut behind her, sending every inch of her supernaturally curvy figure jiggling pleasantly. "I'm your new roommate!"

Hearing this, you couldn't help doing a double-take. "Huh?"

Feeling your eyes on her curves, Sheila grinned. "Your mom didn't tell you I was coming?" 

"No?" Already blushing, you reflexively shrugged. The idea of splitting a room with your best friend's mom — who also happened to be your mom's best friend and the single hottest and most frustratingly flirty 40-year-old woman you'd ever met — was more than enough to get you flustered.

"Alright," said Sheila. "Story time, I guess." Stepping over to your bed, she opened her duffel bag and began emptying its contents — mostly lacy underwear, as far as you could tell from your perch on the nightstand — onto your comforter. "When your mom told the school that you were coming back to campus, they said you needed a caretaker. Someone to take you to your classes, make sure no one kidnapped you, that kind of stuff. I guess it's a legal thing. Obviously her first thought was to do it herself."

"That sounds like her," you said, trying not to stare at the growing pile of bras and thongs. Your mom had expressed considerable reservations about sending you back to college in your current state — even offering to home-school you herself and do her best to recreate the college social experience by chaperoning you to bars and parties — and so the prospect of her volunteering for a program like this was far from far-fetched.

"Only problem was, she couldn't take the time off work." Shaking the last of her clothes out onto the bed, Sheila placed her bag down on the floor and focused her attention squarely on you. "So I offered to sub in."

"Ah, that makes sense," you said, slowly putting two and two together. While your mom had a very demanding job, Sheila's obligations were a lot lighter. Following a highly lucrative career as one of Brazil's most sought-after exotic dancers, she'd taught Portuguese at Storm Valley's Unified Public School—but more as a hobby and a source of pocket change than anything else. There was only one thing about this situation that still didn't add up. "So, uh... where are you gonna sleep? There's only one bed in here..." 

"That's true." Sheila's grin grew. "Looks like we'll have to share."

"Oh... y-yeah." If your face had been feeling warm before this comment, it was now full-on hot. "I guess that works."

"I had a feeling you'd say that." Sheila chuckled. "Don't worry. I promised your mom I'd be gentle with you." 

Before you could respond to this, your new roommate's ass cut in with a word of its own.

BBBRRRRRAAAAAPPPPPPP

You were no stranger to the fact that Sheila had supernaturally bad farts—but now, they were nothing short of a force of nature. In a matter of seconds, her latest blast of gas filled the room like a sea of warm, humid stink, and you were powerless to stop it from sending you into a coughing fit. The only upside was that she'd been facing you when she let loose. If she'd had her butt pointed in your direction, you had no clue how you might have fared.

"Oh my goodness," giggled Sheila, stooping down and waving her hand to help clear away the smell. "Sorry about that, sweetie!" 

"It's okay," you said, shaking your head. As unpleasant as the experience of getting farted on point-blank by someone seventy times your size was, especially someone so familiar, you couldn't help smiling at the sheer absurdity of the whole situation. "I guess I gotta get used to it, right?"

"That's the spirit," said Sheila, returning your smile. "I mean, if the stories Lillian has told me are true, this is kind of your whole thing, right?"

You froze. "My whole... what?"

"You know." Sheila stood up and turned around, giving you an unrestricted view of her huge, round rump. "Having a lady with a big old booty like mine sitting on your face and letting loose." 

"That's not..." You were definitely blushing again—and having Sheila's massive, curvy ass in your face really wasn't helping. While Lillian had several unpleasant habits, her love of teasing you — and staging elaborate pranks to further that teasing — was far and away your least favorite. "I'm not..." 

"Relax, sweetie," Sheila giggled. "I'm kidding. Just wanted to see how you'd react to that." Eyeing your beet-red face — and the telltale stiffness in your pants — she grinned again. "Not exactly a 'no,' as far as I can tell."

"I..." Remembering that Sheila loved pushing you around just as much as her daughter, you sighed. "Can we talk about something else?" 

"Sure," said Sheila, turning around and finally freeing you from the hypnotic spell of her booty.

"Alright," you said, trying to regain some semblance of control over your current situation. "So you're gonna be going to class with me every day? And, like, helping me study and stuff?"

"Funny you should mention that..." Sheila grinned. "Technically, we're going to be classmates!"

For a moment, you hesitated. "Really?"

"Mmm-hmm!" Sheila shrugged. "I figured if I'm gonna be looking after you for the next four years, I might as well have a little fun while I'm at it... plus, I never got the chance to go back in Brazil. So you're looking at SVU's newest freshman!" 

"Oh... I guess that makes sense." Again, you couldn't help smiling. Only your big Brazilian "auntie" would see four years of college as a fun spur-of-the-moment splurge. "Hang on, so you're gonna be my caretaker all the way through graduation?"

"That's right," said Sheila, nodding. "You'll still be back home for holidays and breaks, but you and I are gonna get pretty close between now and then."

"C-cool." At this point, it was all you could do to avoid the elephant in the room. Reflecting on all the comments Sheila had made over the years about "taking you for herself" if you failed to find a girlfriend on your own and the fact that you'd apparently be sharing a bed for at least the next two semesters, it seemed like it was only a matter of time before the sexual tension between you boiled over. For now, of course, you decided it was best to play it safe. "Well... thanks, Sheila. I really appreciate it."

"My pleasure, sweetie." Sheila smiled. "And yours, if you play your cards right."

Laughing off what was clearly one of Sheila's signature overly-forward jokes, you smiled back. Surely, you thought, your best friend's mom had some ulterior motive for signing up for this gig. What that was, though, you had no clue...
