Changing Gears and Sucking Cock

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!
