After a long day, I walk back into my bedroom and find my step brother is sitting on my bed, again, only this time he is waiting for me! He has found something in my room and is trying to decide if he should tell mum and dad about it. It soon becomes clear that he found a dildo in my nightstand and now wishes to watch me use it. If I do he won't tell on me. I informed him that I knew he was sneaking into my room and wanking off into my panties, so fair is fair. Tell on me and I will tell on you! Initially I am not so sure about it but I quickly give in because I have a plug up my butt and it's made me horny. I was going to fuck myself anyway, so he may as well watch.
