How Do You Know Me?

I only come here when you call me at night I only come in when you don't wanna ask twice I thought it was clear That we don't tell anybody About what we do we're alone And wanna dim the lights But if we ever get caught Out and about By one of your girlfriends I don't mind You can ask me How I know you But It's your boyfriend You have to tell him How do you know me? Go on tell him How do you know me? I know he's seen me before tell me How do you know me? I always creep in, slow and quiet I never sleep in, in case he's in town and I never call you Before you text first To tell me he's gone So I can feel your body But if we ever get caught Out and about By one of your girlfriends I don't mind You can ask me How I know you But It's your boyfriend You have to tell him How do you know me? Go on tell him How do you know me? I know he's seen me before tell him How do you know me? How do you know me? Go on tell him How do you know me? I know he's wondering How I know you How do you know me?
