"Sister, did you show your boobs on the webcam? Then show me some."

Brother, let me live for a week, I'll even jerk off and suck your dick

Sister, it's too late to show off — you showed your tits, now give me your pussy

Sister, is it really okay to touch my boobs? And you can't even tell your mother?
