Fandom: Star Trek AOS
Summary: It’s not game on after that. Bones doesn’t start petting him left and right or anything. But if Jim gets into the right position and Bones is sleepy enough, it happens. And when it happens, Jim’s basically in aroused heaven for a few days. He’s always liked his hair pulled, but it’s never been this big a thing. He’s never spent actual hours of his life trying to plan out non-dates that will end with a little fingers-on-scalp action. It’s like he doesn’t even know himself.
