I am married and have been for almost 40 years to the same woman. I love her but I am very sexual and she is only modestly so. Our sex is OK but nothing like my dreams. Maybe I'm overreacting but I have some huge fantasies, some of which I have acted on and others remain just thoughts. About 25 years ago I had this extremely hot neighbor who was probably 15 years older than me. She was divorced and always did her yard wok wearing the skimpiest clothes I ended up watching her lustfully as much as I could. I jerked off looking out my basement window many times. She could see me there but not see what I was doing because the window was so high. One night I saw her while I was out with my dog, standing in her kitchen looking into her fridge. The room lights were off but the dim fridge light revealed she was totally nude. I found myself obsessing over her but never said a word to her. My heart would race as I thought of how wild the sex might be with her. I found myself sneaking around her windows at night waiting to see if she would appear naked and was often rewarded. I would watch her and jerk off maybe once a week. NO lights in her back yard so it was always very dark. One night I woke up about midnight and to this day I can't believe I did this, But I got out of bed and went to her window. Seeing no lights I walked over to her garage door and tried it. To my shock and amazement it was open. Still don't know what prompted me to do that, but as it was open I found myself walking into her kitchen. I was only wearing boxers and slipped them off completely. Now totally naked I began stroking what was almost immediately a raging erection. I very slowly walked towards her stairs leading up to her bedroom. My heart was racing but I was totally lost in lust. I crept up her stairs and could now hear her breathing. IN another minute I was standing at her bedroom door looking at her naked body spread out on her bed, the only light being a night light in her bathroom. I stood there stroking my extremely hard erection until I could hold it no more and shot a huge load into her bedroom. I could see it lay a trail 3 feet long on her carpet. She didn't move and my heart raced even harder. As slowly as I could I left her house the same way I had come in, very slowly and quietly. To be honest, it was the most sexually stimulating thing I have ever done, and also the most dangerous. I never did it again but continued watching her as I could catch her moving around her house at night naked. She moved about a year later and I have no idea if she ever saw me. I still masturbate to those thoughts.
