Two woman I work with and myself began renting a house together almost two years ago for financial reasons. Helen has a son Todd who is 19 now and he sleeps in the first floor den we made into a bedroom. Helen and I share a Jack and Jill bathroom which is perfect for both of us since Helen always works the 3 to 11 shift and I work daytime. Eight or nine months ago I became aware that Todd was going into his mother room at night. Somehow he pried and opening on one side of the door where the molding must be and has been watching me since then. Its embarrassing to admit this but I totally enjoy and am aroused knowing he is watching me. I doubt he knows I can see his eye in the opening and he seems to be so sure he is undetected he doesn't even turn the lights off in Helens room. There has been times Helen has said things in front of both Todd and I mentioning how he leaves her room a mess sometimes. She told him in front of me not to leave his trash or any of his clothes when he is there. Helen really has no inkling why Todd is in her room at night thinking its only because she has a large TV. I assume Todd has been watching me longer than I have known he was and shame on me for never feeling embarrassed or upset about it. I had never before did anything like this and am surprised at myself for my lack of modesty or being humiliated by it. He not only sees me shower but I have no problem using the toilet or even changing a tampon knowing he is looking in at me. I let him watch me masturbate and for many years I have shaved my pubic hair and still do with Todd watching me. I do have a boyfriend and have sex regularly but find I masturbate more when I know Todd is watching. I am so at ease exposing myself to him I find myself positioning my body in ways I never did before allowing him to see me as intimately as possible. I turn my back to him bending down while shaving my legs, exposing my vagina and anus in ways my boyfriend has never seen me. I see and talk to Todd everyday never letting on I know he is watching me most weeknights. I never feel embarrassed by it yet can't think of a reason for letting him see me in every personal thing I do with my body. At times I can hear him breathing or making sounds and I am pretty sure he masturbates often while watching me. He is a laid back type and sort of a wimp around his mother. Has a part time job and goes to community college a few days a week. He is not dumb but when he is in Helens room he is careless and considers himself undetectable even with the lights on. In a way I feel guilty because Helen is such a sweet woman but it arouses me so much I just let it happen. I'm convinced that Todd is confident that I don't know he is watching me so often. He is always smiling when I am downstairs and I have a good idea what he is thinking about me. Its ok with me because he doesn't know how much fun I am having and how arousing it is for me.
