You and Billy had just had a hook up in his room when his dad came in. You immediately pulled the covers up over your chest

His dad yelled at him as soon as he saw you in his bed. Billy simply grabbed a cigarette and lit it, seemingly unfazed by his dads anger/disappointment

The second his dad slammed the door behind him, Billy turned to you with a mostly stoic expression. He let out a puff of smoke and put his cigarette out in the ash tray on the bedside table
