Bruce is my business partner and my best friend for many years. He's married and has a 15 year old daughter Alene and a 12 year old son Bobby. He lives in a fantastic beach house in Fort Meyers, Florida and I stay there Friday and Saturday nights in the guest bedroom. There is an outside wrap around deck on the second floor and I know for sure that his daughter peeks into both the bedroom and bathroom I use. I'm not exactly sure how long she has been doing it but I have been aware of it for 5 months now. All the windows face the beach so I was never concerned about my privacy since the house sits up so high. I should have told Bruce or his wife about it when I found out she was peeking in my windows at night but never did. I have never spoken to anyone about it and keep letting her watch me. I'm 38, never been married and as I type this only have a off and on girlfriend who at present I have talked to in three weeks. It excites me knowing when Arlene is watching me and seeing me naked on weekends. She watches me shower and ever since I found out she is looking in my windows I began masturbating more often than before. its like she knows my timing and can predict when I am going to change or get a shower. To look into my bathroom she stands on one of the deck chairs. I placed a toothpick under the leg a few times and know the chair has been moved. In the bedroom is a sliding door and a window but she never peeks in at the sliding door since its so open. I jerk off in the shower sometimes but mostly do it in the bedroom after I shower and stay naked the rest of the night unless we go out somewhere. She is sneaky and smart because she is never out on the deck until it is dark out. I see Arlene often over the weekends but don't ever give her any inclination that I'm aware of her peeking in at me. Knowing she is watching me when I jerk off has me excited so much I seem to ejaculate more semen than usual. Its to late now to tell Bruce about Alene and if anything I would let either Bruce or his wife to find out on their own. It would be devastating if they knew I was knowingly allowing Arlene to see me naked and even worse seeing me masturbate. So I just go along pretending I know nothing about her doing this. As guilty as I am Arlene is also since she has probably been doing it long before I found out.
