Taking someone's cigarette out of their mouth: Multiple meanings - used a lot in media to convey control, power play, very masculine, I'm your boss and this is mine now, get over it. Mildly flirty, look at me, all in your space and shit, seductive. You're not allowed to smoke, because I say so.
Putting the cigarette back in their mouth afterwards: Ground-breaking. Would be less erotic to just fuck honestly. Who does this?
