Looks like you left the door open knowing I would walk right in on you while you were jerking off. It's like you WANTED me to see, to catch you in a depraved and perverted state, eager to be laughed at while you masturbate. It's a perfect situation--your cock out, on your knees, and a pretty girl who'll humiliate you and tell you EXACTLY how to stroke. You just can't get off to anything else, only I can embarrass you, change you, and ruin any sense of normalcy that's left in your life--and you LOVE it.
