I'm 17 and straight but after splitting up with my boyfriend, I did something which was a surprise to me. I was at a party. On my way home I saw Rhea- this pretty girl from my year at school. She said she would walk home with me and I said she could come in to my house to hang out. It sounded like a good idea.
Anyway, we went up to my room and she said it would be funny to swap our pants(what we call knickers in the UK.) It seemed like a fun thing to do so we did it. My pants were quite tight for her but she looked hot in them. I got really turned on by this and asked her if she masturbated. She said she hadn't done it before.
This turned out to be a lie but I was fooled at the time as she asked me to show her and to do her. I pushed her onto the bed and started rubbing her through the pants she was wearing. She started moaning loudly and then as I rubbed more she came. She totally soaked my pants that she was wearing but it turned me on so much that I was dripping by now.
We fell asleep together and woke up with bad hangovers but we did more stuff in the morning. I licked her out and masturbated onto her while she was sleeping. I felt so guilty after doing it and now she ignores me. I always masturbate wearing the pants she was wearing that night. I'm still straight but there's just something about her that is so hot and I'll never forget that night even if she never speaks to me again.
