Summary
     Charlie needs help with physics; his teacher suspects he has other
     things on his mind.
Notes
     For the community hpshortfics, challenge of "American high school
     AU," and it actually turned into a fic instead of a drabble...whoops!
"Mr. Black?"
"Regulus, please." Regulus smiled as Charlie peeked around the door. "Come in."
"Mr--Regulus, I had a question about the physics homework?"
"Sure." Regulus shuffled some papers off his desk. He hadn't yet figured out
how all the Weasleys--so poor--had made it into this particular school system,
but it was probably something to do with family connections. Charlie wasn't
somebody to refuse.
"I'm having a little trouble understanding angula--" Charlie waited while the
three-oh-five bell rang. "--angular momentum," he finished.
Regulus smiled encouragingly. "Can you give me a little more?"
"Well, it doesn't seem like anything should be...coming out of the, um, the
plane of rotation like that?"
"Ah, yes. All right." Regulus stood up, walked over to his bookshelf, and
picked up one of his tops. "See, when you spin it, you've got a bunch of little
pieces, all going in different--" It slipped out of his fingers.
"Oh, I'll--" said Charlie, as they both went for it. Regulus snagged the toy
just as Charlie's fingers brushed his own. He looked up, and the boy's eyes
were on his, wide and blue, and he was blushing, and suddenly Regulus knew.
"Anyway," Regulus said, softly, without straightening, "we know there's
something there that wants to keep spinning, but the only math we know for it
is straight out. You'll understand it when you've had something called
vectors."
"Okay," Charlie breathed.
Regulus stood. "There's something else I thought you could help me with?"
Charlie looked surprised. "All right."
"Step over here, please," he said.
He had time to wonder, while Charlie followed him behind his desk, if he really
ought to be doing this. The boy was....what....this was near the end of their
tenth grade, so he was...sixteen? But so eager. And thick, solid, unlike the
whip-thin look that was so prized in the Black family.
Charlie stopped, uncertain, next to Regulus's chair. Regulus glanced at the
door, then reached his hand up and wrapped his fingers around the boy's neck.
He could still stop this, he knew, but...Charlie sighed and blinked slowly, and
that was it.
Regulus leaned in and kissed him.
Charlie moaned immediately, which was...oh. Regulus dropped a hand to Charlie's
waist and pulled their bodies flush together. His technique was sloppy, and
much too eager, but somehow he was just sweet, and Regulus was just about to
sit down with the boy in his lap when the three-ten bell rang for detention.
Charlie sprang back, hair a little messy, lips red. "Oh, I'm sorry, I," he
licked his lips, unaware of what it was doing to Regulus, "I really ought to--"
Someone knocked.
Charlie blushed, and Regulus did the only thing he could think of: grabbed his
wrist and practically threw him in the kneehole of the desk. Cliche, but
effective. Nobody'd be able to miss what was going on if he was visible.
"Regulus," Snape said. "The physics team is encroaching upon chemistry club
time."
"Snape, good to see you too," Regulus said. He sat down and tried to relax in
his chair, rolling forward more so Charlie would be even better hidden.
"I want your meetings moved."
Regulus coughed, covering the sigh he would have made from Charlie's fingers
skating along his thigh. "You have a smaller membership," he pointed out.
Snape sneered.
"Vinegar and honey, Snape," Regulus said.
"Yes. Well."
Regulus hurriedly shuffled some papers on his desk to cover the sound of his
zipper going down. What was the boy *doing*?
"I'll move the chemistry club," Snape said grudgingly, "if you'll let the
physics team members go to State next week instead of the all-city physics
day."
"Done," Regulus said, rather loudly, as he felt Charlie lick his cock. Quick
study--but then he always had been, in class....
Snape shut the door abruptly, and Regulus let out a sigh. No need to let Snape
know he would have released the students anyway...but...God...no time to think
about that know. He looked down, and Charlie looked back up at him, mouth red
along Regulus's cock.
"Can I?"
Good God. "Of course," Regulus said, and then there was heat, and warmth, and
wet. Charlie didn't really know what he was doing...but there were just things
you forgave. Regulus reached down and curled his fingers through the fiery
strands of Charlie's hair. With that control of the boy's movements, it was
only a couple of minutes before he gasped, "I'm close," and Charlie just smiled
and kept on.
He didn't handle the end quite as well as might be hoped--coughed a couple of
times before spitting in the garbage can. Regulus grabbed him by the neck again
and pulled him up, kissed those more-swollen lips and dug one hand into
Charlie's trousers. One, two, three and warmth covered his fingers, viscous and
thick.
After a beat of staring at each other, Regulus fell back into his chair, and
Charlie, pink and bright-eyed, tidied his clothing. "I, um," he said, "I need
to get my brothers home."
"All right," Regulus nodded.
"I'll just--" Charlie went for the door. "I. Thanks."
"No," and Regulus made his voice go quiet in that way he knew the boy would
read, "thank *you*."
Charlie smiled, a little, and slipped out.
Regulus grabbed some tissues from the desk and wiped his fingers off. That last
image of red hair, backpack slung over the shoulder...well.
He felt bad.
But he didn't feel quite bad enough.
