I was sharing a room with my step-sister, but I got caught masturbating eight times a day! My step-sister was angry at the daily noise of my masturbation, so for some reason she made a ridiculous suggestion to me that I'd give her a handjob just once. I told her I couldn't do that, but she made a shocking confession: "I used to do it every day before we lived together..." We were a sultry brother and sister. Of course, neither of us could resist that! In the end, we ended up having sex over the partition of a single curtain! No more masturbation!
