Summary
     A modern setting highschool AU in which Bruce is a science teacher
     and Steve has a helpless crush on him. PWP ftw!
It started out as an innocent favor. Mr. Banner just needed help putting away
all the equipment used in today's lesson. Who better to ask than his star
pupil, Steve Rogers? If it had been any of his other students he would've had
to bend over backwards and say it was extra credit, but Steve was more than
eager to help. Bruce didn't have to bat his eyelashes or nothing.
He knew very well why Steve liked him so much, the boy's affection for the
older man was painfully obvious. Well into the school year Steve had been
dubbed teacher's pet because he was always so eager to prove himself to Mr.
Banner by any means. Steve had gotten a lot of razzing from Bucky but he didn't
mind it much. Steve had a crush on his science teacher and he thought it was
love just like the rest of the teenagers with their silly infatuations.
But most teenagers don't act upon their desires, especially towards their
teachers.
So here he was with Mr. Banner, alone and very naked, sprawled across the older
man's desk, waiting in anticipation for what was to come. Sometime during
cleaning up Steve had accidentally brushed against his teacher and, knowing
just how much Steve was in love with him, Mr. Banner exploited it by flirting
with the smaller man, making him blush like the virgin he was. Bruce knew it
was wrong to encourage the kid's feelings and it was even more wrong to kiss
him.
It wasn't very nice of Bruce to take advantage of Steve's emotions but even as
he undressed the young man he couldn't deny his own feelings for Steve. Steve
was scrawny and short but he was also sharp and eager to please his elders,
always willing himself to be the best in class. Bruce really admired the kid's
persistence in his academics.
When Steve was bare to Bruce's eyes he retreated internally slightly, hiding
himself out of habit. Bruce had reached out to cup Steve's face in his warm
hands and pulled him into a tender kiss. Steve had never been kissed before and
he never expected it to be as romantic as they were depicted in the movies. He
thought that was just all talk. But Mr. Banner held his thin face and didn't
part his lips once, being a gentlemen and starting out slow.
Steve was somehow led over to Mr. Banner's desk during the kiss and was picked
up in strong arms to be set down on top of it. Bruce was still dressed. He
didn't even loosen his tie yet. Steve felt naked in every sense of the word.
Seeming to read his mind, Bruce began to unbutton his dress shirt, pulling it
out of his pants from where it was tucked in and loosening his tie just a
little. Steve couldn't believe how sexy that alone looked.
After many fumbles for his fly, Bruce undid his pants as his tongue explored
Steve's mouth with gentle curiosity, probing in all the right places. Bruce
pulled back, leaving Steve panting and breathless from the intensity of the
kiss. Steve peered up at Mr. Banner's body, scanning greedily and trying to
mesmerize every inch of him. He took in the way Mr. Banner's shirt had slipped
off his shoulders and onto the floor or how his pants hung loosely on his hips.
There was a telltale outline of a bulge in Bruce's underwear and Steve felt
himself shiver at the thought alone. Bruce still had his tie on too. It all
happened so fast that, when Steve saw Mr. Banner pulling his cock out and
pushing him back against the hard wooden surface of the desk, he didn't realize
how this would end. Steve began to panic a little because Mr. Banner was
expecting sex and Steve had been too preoccupied to notice.
"Mr. banner, I've never done anything like this before," Steve admitted with a
blush, stating the obvious just to stall a little.
"Don't worry," Bruce whispered into Steve's ear. "I'll be gentle. Promise."
And he was.
It had hurt when Mr. Banner initially entered him and a little while afterwards
but he was taking his time and going slow, making sure Steve could relax and
adjust gradually. Bruce hunched over the kid's body and began to slowly thrust
in and out, hooking his arms under the back of Steve's knees to spread him
apart, granting him better access. And when Steve started to squirm and moan
the older man got more bold.
He pulled Steve off of the desk to turn him around, pushing him down against
the cold surface and re-entering the tight entrance. Steve lurched forward and
let out a moan that sounded like it was punched out of him. Steve's arms
extended across the desktop to grip the edge, knocking off papers and turning
his knuckles white from the death grip. It was hard for Steve to stay up,
balancing on his tiptoes, but it was definitely hotter.
Bruce's hands gripped Steve's slim hips and in the middle of strained breathes
and stuttering thrusts, Bruce just couldn't believe how tiny Steve was in so
many ways. He couldn't even believe that he was actually fucking one of his
students despite the fact that his cock was buried deep inside of Steve and on
the verge of exploding.
Steve was moaning but not loud enough for anyone to hear who happened to be
walking by. He idly let one of his hands go down to his cock to stroke himself
in time with Mr. Banner's thrusts, finding his orgasm soon after as his teacher
continued to pump inside of him. Bruce's pace only quickened slightly near the
end.
Just before Bruce came he pulled out of Steve and gripped himself at the base
of his cock, letting go to come between Steve's spread legs and onto the floor.
It had been stupid enough to fuck his student without a condom and he didn't
feel like defiling the kid further by coming inside him. But even as he was
acknowledging Steve's personal space he could hear the kid sighing and moaning
like he was let down.
"You didn't have to pull out," Steve said meekly as he turned around, shrinking
into himself once again.
"Well, there's always next time," Bruce grinned slyly. "Just don't tattle on
me."
Steve blushed, smiling at the promise of a second time.
"Deal."
