What I have been doing for the last 7 months is shameful but instead of embarrassing me, it arouses me. I’m 41 years old and live in a large trailer with my boyfriend Rob who is 45. His son Ricky is 15 and visits us every other weekend as per court order. The bathroom and shower in the trailer is small but adequate. The door enclosing the bathroom is a sliding door which has been out of whack and slips of the track all the time. I knew it wasn’t fully closed for a long time but never imagined Ricky would peek in at me knowing I’m in the shower. The fact is I can see his eyes when he does it and from the very fist time I noticed he was watching me I was never embarrassed by him seeing me naked. When he is here its from Friday evening until Sunday evening and he watches me shower at least once each weekend. I do feel ashamed at times and know I should tell Rob about it but, I get so aroused when Ricky watches me I end up masturbating. He is always overly friendly and polite with me so I’m sure this is the reason.
