My instructor asked me to spar while he was naked and I stayed clothed - 19F

So, for my senior year, I needed to do some kind of extracurricular sport for a semester. I ended up picking Brazilian jiu-jitsu because my dad thought it would be good for self-defense before I went off to college.

The first day was kinda scary, but there were other girls there, which was cool. The head coach was super professional and made the classes really educational. I actually had a lot of fun sparring with everyone and getting the confidence to defend myself against guys. The weeks went by fast, and I told my coach it was my last week. He didn't realize I was only doing it for school and thought I was a regular student. He was bummed! He asked me to stay and said I was a great student. I told him I was moving out of state, so it wasn't possible.

He was obviously sad the last few classes and made sure they were extra helpful. On my last day, he asked me to stay after class. I thought he just wanted to say goodbye. After everyone left, we went to his office, and things got weird. He looked really upset and asked if there was anything he could do to change my mind. He started pacing and sweating, then asked if I could do him a favor without freaking out. I said sure since I trusted him. He told me he "loved everything about me" and would pay anything – not for sex or a date – but just to do one thing...

He begged me to spar with him while he was naked. He said I didn't have to be naked and that it was his dream to do this. He talked about his passion for the sport and how liberating it would be. It was kinda crazy how desperate he was. I was hesitant, but he kept begging and even offered to "help" me with school. That's what got me, and I agreed.

He was SO happy. We went to the mat, and he asked me a million times if I was okay with it. Then, he dropped his shorts. He had a little bit of a hard-on, and he had this goofy but cute grin on his face. He looked so proud. We started sparring, and after about 15 minutes, he took off his briefs too.

It was a super weird experience. He wasn't being creepy or anything. He sparred just like he did in class. I could feel his dick rubbing against me, mostly on my butt. It would get hard sometimes, sometimes soft. His balls would also roll around as we practiced. After an hour, we were done, and he said it was the most freeing thing ever."
