Scott- lift up your shirt, right in front of his eyes, to show him you forgot to wear a bra. Oops. 😉
Stiles- Walk around his room while he works in one of his baggy shirts. Literally nothing else.
Derek- wear a really shirt skirt, and sit so he has an eye level with your groin, and slowly reveal to him you aren't wearing panties, and are desperately wet for him. If he's being particularly stubborn that day, you finger yourself.
Jackson- threaten to not answer his booty calls for a week if he doesn't give up and fuck you. Promise to blow him every day for a week if he does.
Isaac- Sit next to him as he's working, and slowly slide your hand up his thigh, until it's resting over his crotch, which is getting hard, let's be real. And when he gives up it's handjob time
