A/N: [Written for Livejournal's comment_fic comm.] This here is a ficlet. I'm thinking that any Jalex fics I do below 900 words should be apart of this. Btw, stripteases seem silly to me and my description of it here probably kind of sucks, but whatever.
Warnings: Incest, masturbation, sexual situations, UST.

Summary: When Justin loses a bet with Alex, he's forced to do something that makes him uncomfortable. The fact that Alex gets a kick out of it probably isn't a good sign.
Nudging her brother, Alex grinned at him ferally making the the older teen feel even more uncomfortable. She hooked her thumbs into his jeans and tugged his hips forward so they pressed against her. Justin prayed his little soldier behaved as he squirmed from the friction.
"I'm not doing it." He stated as firmly as the quiver in his voice allowed.
"Come on, you have to do it. I won the bet fair and square." Alex coaxed, pressing her lips lightly to his chin. "Plus, I'll make it worth your while."
Cursing to himself as his little solider twitched in excitement despite his discomfort, Justin sighed dramatically. "Fine. I'll do it, but you better not laugh."
Stepping back, the younger teen nodded in agreement and motioned for her brother to get on with his task. Blushing, Justin moved back and hit play on the radio. A steady electronica beat emitted from the speakers and he began to shake his behind to the beat. He reached for the buttons of his shirt, all the while he closed his eyes trying to focus on the embarrassing task ahead of him
"Turn around and strip. I wanna see your butt wiggling." His sister said with a purr.
Doing as he was asked, Justin removed his shirt slowly, throwing it to the side. Moving to his pants, he undid the button and zipper, making sure to keep wiggling his butt to the music. There was movement behind him as Alex sat on the bed.
"Am I done?" Justin asked, eager to be done with the striptease.
"I don't see your pants off."
Sighing and rolling his eyes, he removed his pants, the music still urging him even as commonsense said this was stupid. He paused, unsure if he should take off the last article of clothing. Behind him, he caught the sound of light panting and his little soldier stretched uncomfortably in his tightie whities.
"I dunno. Are you done stripping? Because I still see something in the way of that wiggling butt."
Heart racing, he stepped up his dancing, showing off his physique the best he could, feeling clumsy and stupid. The sounds behind him spoke enough for him to know that at least Alex was enjoying it. Finally, the music began to wind down so he moved for his underwear, sliding them down his legs and bending over purposely so Alex could get eyeful of his goods, including his erection. Standing up, the next song coming on, Justin held his breath, waiting for his next instructions.
"Jerk yourself off."
"That wasn't part of the deal."
"It is now."
"You suck." Justin whined as he gripped himself.
"Not at the moment." Alex laughed.
"Do you want me to do this or not?" He threatened.
"Sorry, I couldn't help it."
Justin began jerking himself off, grumbling. Behind him, he could hear Alex's breath hitch and he blanched at the fact that she just probably got herself off watching him. The bed behind him shifted as Alex rearranged herself. When nails scratched up his butt, he jumped forward, almost hitting his head on a protruding shelf.
"Chicken." Alex said.
"No, you just surprised me." Justin argued, trying to maintain his dignity.
His sister gave him a look of 'bullshit' before smiling and reaching for his head with one hand, the other brushed against his hip, smirking at the shiver she received in response. "Want me to kiss it and make it better?"
"Yes." Justin said, his hand still moving against his erection.
Pressing her lips to his forehead, Alex touched his balls, cradling them in her hand. Right there, at the edge of release, turned on by listening to his sister get off, Alex laughed and moved away toward the door, leaving her brother standing there.
"Hey, where are you going?" Justin asked confused.
"I'm going to get a snack. You look busy." With that, Alex had slipped out the door, leaving her brother with his cock in his hand.
Alex had totally just used him for her own enjoyment.
"Son of a bitch!"
