He slumps on her. He has to. His body turns into noodles and water and he just lays limply on top of her, panting and trying not to look too utterly pathetic (and failing). His brain was lying in a puddle in the reservoir tip of the condom, that imagery reminding him to slide a hand down, find the base, and hold it as he moves to slip out of her.

Oooh... he doesn't want to leave. She's so warm and inviting...

But hey, no Stilinski wolves. Bad idea.
