I grew up in rural America with two sister that were both older than me. My mom always walked around naked. It was nothing to see her in the nude and to be honest I never thought anything of it because it was just so normal. I never thought of my family in a sexual way until one evening I was at my oldest sisters apartment. I was watching tv and she went to go take a bath. She had a roommate but she wasn’t home. At some point I went to walk into the kitchen and walked by the bathroom door. As I did I saw light coming from the side of the door which I thought was weird since the door was closed. Naturally I had to look. Part of the door jam was missing so I had a very clear shot of my sister. She was in the bathtub shoving her hips up. I could tell that she had a bush but couldn’t really tell how well maintained she kept it because I was looking from the side. She had what looked like soap on her middle finger which was running up and down her slit. I couldn’t believe it. This was the first time thinking about my family member in a sexual way. I got so excited so fast, my dick was rock hard and my hands were shaking. I began thinking of a reason to talk to her through the door and hopefully go in. All I could think of was telling her some show had started. I grabbed the doorknob which she apparently heard and yelled at me not to come in. I settled and jerked off. I was so scared her roommate was gonna walk in and catch me watching my sister. Luckily that didn’t happen. I blew my load and used my underwear to clean up my mess since I couldn’t get into the bathroom. After that experience I made it a point to spy on both my sisters and my mom.
This is the first time but I have many other stories to share. This all also happened before cellphones where really a thing so I don’t have pics so don’t ask.
