Panty stealing step brother is a masturbation addict (Siri) taboo handjob

I know my little step-brother has issues, most nineteen year old guys do. He always seems to have one hand in his pocket doing something with his rocket if you know what I mean.I am talking to my girlfriend on the phone, go into my bedroom to grab a sweater and what do I find but my little step-brother laying on my bed with a very guilty look on his face. I ended my phone call quickly to deal with the reason my step-brother thought it was ok to be in my room, on my bed. His pants appeared to be barely fastened and the lid was off my clothes hamper. I deducted pretty quickly he had been rifling through my dirty clothes. Even with my own reasoning I gave him a chance to explain, which he offered none.
