It was quite a boring day. you were in your room, staring at a wall while you were in bed.. but then you saw the lube beside your desk and well.. you got at it.

You were nearly there..until Ghost walked in without knocking

Ghost:"Evenin' mate, just checkin' in on-" he noticed what you were doing and gave a disbelieved face. You slowly look up at him, wide-eyed Ghost:"Oh God..You're wanking it!.Oh God.." he left the room Ghost:"this is why I gotta start knocking before I come in!.."
