Scott- he'll slack off, making you feel like you're doing all the work, until you ask what's wrong. He'll lean in to kiss you, and grab your hand, bringing it to his erection, making you gasp into the kiss.
Stiles- he'll whine and try to distract you from what your doing. You know exactly what's up. You'll drag out what you're doing, just to tease him.
Derek- He'll grab you, no matter what's going on, and take you somewhere private. He'll press himself against you so you can feel him, and you'll not as a confirmation, before he'll press you against the mattress, surface of wall, and do you.
Jackson- call you. Booty call. You're always down for it, as he never fails to please. You'll make you way to his as soon as you possibly can.
Isaac- he'll come find you, when you're standing doing something, like cooking or cleaning, and he'll wrap his arms around your waist. He'll whisper dirty things into your ear, making you blush, and he'll grind his boner against you, to make it obvious how much he wants you.
