For those of you who do not know, I OWN NOTHING! cries This is an AU story, meaning not everything is as it was in the books. Sirius is a bit of an outcast and James is...well...James.
"Let me see if I heard what I think I just did," Sirius Black laughed. "You, James Potter, want me to pretend to be your boyfriend to make Lily Evans jealous?"
James stood there in all his arrogant glory.
"Yes."
Sirius raised a single eyebrow.
"Why on earth would she want you if she thinks you're gay?"
"I'll tell everyone I'm bi."
"And what will you tell them about your sudden interest in the Gryffindor reject?"
James sighed.
"I'll tell them I wanted a change, someone different."
Sirius snorted, amused.
Different they were all right. James Potter was the well dressed, well spoken, 'I wish my son was more like that' miracle child of the wizarding world's two most highly acclaimed politicians.
Sirius Black, on the other hand, was the rebel child of one of the oldest lines of purebloods. It wasn't uncommon to spot him, cigarette in hand, walking around Hogwarts with his torn, worn-out jeans, kohl eyeliner, and a t-shirt matching whatever color he currently had streaked through his hair.
"You really think this will work?"
"You don't?" James challenged.
"No, I don't."
Sighing, James ran a hand through his mop of unruly hair.
"Will you do it?"
"Why should I?"
"It'll get Malfoy off your back."
"I can turn down Malfoy without your little plan."
Sirius turned to leave the common room.
"I'll buy you that guitar you want," James called out, desperate.
Sirius paused two feet from the door.
"The fender stratocaster?"
"Yes. You can get the new Zeppelin album, too."
James could tell the boy was tempted, but Sirius wasn't quite ready to give in yet.
"I'll take you shopping! Clothes, albums, posters, makeup, parts for that motor-deathtrap of yours, anything you want!"
"……anything?"
James sighed in relief.
"Anything."
Sirius hesitated before nodding, biting his lip, and James watched him walk out of the room.
"Well," James sighed, "the hardest part is over, at least."
