Got off while my female friend sat in my lap during a long road trip
This was right after my college when I joined a MNC and made new friends in the training period. We had a big group which hung out together mostly on weekends. In the Christmas to New year holidays we planned a trip to a nearby hill station.
It was a 6 hour drive in a crowded car. And there were 9 of us 5 girls and 4 guys. I already had a good repo with all the girls and really had eyes on two of them. One of them was the smallest and petite so I made her sit on my lap the whole time. I was holding her on my lap on the second row. We were going through windy roads so to keep her from moving around too much I had wrapped my arms around my waist.
With the way I was holding her I could feel my cock rub against her, between her legs. It was late at night so everyone was quiet or sleeping except the driver and the friend at the front. She had one hand on the handle above the window and the other on my arm that was around her waist
The car just kept jostling around and I could feel getting hard for her. It was turning me on so much that I slowly positioned myself such that she would spread her legs a bit more to rub against me. She was wearing leggings and I was sure she could really feel everything. And I could tell what she was doing when she started grinding in a rhythm so I switched to holding either side of her hips. I kind of pinned her against myself and every time the car swayed we rubbed against each other harder. Her breathing was getting harder and she could hear me groan too quietly sometimes. Eventually I came and a few minutes later she did too and then she fell against me. I let her take a nap leaning on me while I occasionally felt her thighs and hips.
