I like being watched

When i was 18yrs old i went to stay with my dad for a few weeks were he lived with his new wife and her two kids.My parents had got divorced a few years before,and i lived with my mom and my sister. My step sister was 11 and my step brother was 13. His room was next to the bathroom and the stairs coming down from upstairs. There was access to plumbing etc through a crawl space under the stairs,accesed through a door inside the room closet. My step brother showed me the space and said he used it as a fort. I went into the little space and discovered that you could see right into the shower because there were big gaps through the tiles,were the plumbing came through. I wondered if my step bro ever looked when people were showering,so next time i went in,i kept an eye out for any activity i could see through the cracks.Sure enough i noticed movement and i knew my step brother was in there,looking at me naked in the shower! I got really excited about the prospect of showing of my big cock nice and hard! I turned my back to the wall and worked my dick up big and hard with the soap lather....then i turned around towards the peep hole to show off my big boner! I played with it for a bit,soaping up....jerking....touching myself etc. I knew he had watched me,cause when i came out of the bathroom,he asked me with a sneaky smile if i had a good shower! I said with smerk,yeah it felt great! My biggest show was yet to come.....that story is in the next blog.
