Adriana Rys had her exam in two days, so we got into the Mean Orange Machine for her final lesson. She was doing very well, and I was very horny, so while she drove, I took out my dick and hid it behind my clipboard as I wanked myself. I asked Adriana if she had a boyfriend, and she informed me she liked sex too much so she did not do the whole monogamy thing. I took a risk, and put her hand on my cock. To my delight, she took over stroking it. We pulled over and she gave me a sloppy blowjob, then she climbed on top of me and took my dick in her pussy. She bounced her big ass on my cock, then we fucked missionary. Finally, I pulled out, and came on her pussy!
