I have been married for a year now and my husband and I are living with his parents so we can save enough to by a house. My husbands brother Josh, who is 19, also lives here. The problem is that my husband and I share a Jack and Jill bathroom with Josh and about 4 months ago thought I noticed he has been peeping in at me when I shower. I had a feeling he was spying on me but wasn't sure how he did it. Theres was no one home and I went into Josh's room and started looking around by his bathroom door but couldn't see any way he could see into the bathroom. Then I noticed a small nail sticking out of the wooded sash running down the lengh of the door by the doorknob. On his dresser was a little pen knife. The more I looked at the wood peice it seemed like it was loose. I took the pen knife and as soon as I pushed it slightly under the wood it open up leaving a slit about a half inch wide of an opening into the bathroom. When I looked in I could see directly into the shower and now know Josh has been watching me since we moved in. I know this sounds rediculous but it gets me aroused knowing he is watching me and many times I have initiated sex with my husband because of it. I have masturbated at times but never let Josh see me doing that. He does watch me shave my pubic hair and legs but I never let him see me masturbate. Thankfully Josh can't see the toilet from the angle the door is on but he can see the double sinks. Josh always seems to go to his room right before the time I usually get my shower so I know he watches me most of the time especially during the weekdays. I know I'll regret this someday but right now it excites me knowing he is seeing me nude.
