As I drove down the highway, it was all I could do not to pull my cock out and start stroking right then and there. The anticipation and knowing what...I was about to do had me so incredibly horny. I got there a little early, and parked where I could see the picnic tables. There weren't a lot of cars there, and only a couple trucks idling in the lot.After a couple minutes, I saw a woman pull in and get out of her car. She was blonde, with long straight hair down to her ass, and chubby in that. I would still have to take tests and deliver my lab work on campus, but I could go there off and on without the professors and TAs penalizing me for missing class."I started giggling. I don't know why, but I couldn't stop. It grew and grew until I heard him start to laugh at me on the other end. After a couple of minutes I got myself under control and wiped my eyes."I take it you'd be OK with that?" He was still chuckling."Yes," I squeaked. I didn't trust myself to stay more than that without. I was getting so turned on with the nurse sucking and licking my tits and the doctor playing with my cunt that I had already cum twice. He then started inserting his latex wrapped fingers into my cunt. He had three in me and was finger fucking me making me scream and multi cum. I never wanted wanted the tit sucking and finger fucking to stop. But he did stop only long enough to stick his cock into my hole. Now this was a huge cock and when he pushed it in I felt the walls of my cunt stretch to. Then he thought about Joann, a gorgeous blonde with big blue eyes who had breasts that were big and firm. His thoughts ran wilder as the thought about Laura and Joann together with him in a nice sex sandwich.Patrick looked down to realize he'd just cum all over his hand. He hadn't even felt his own warm man liquid on himself being so lost in his fantasy."Oh fuck!" Patrick gasped after his erotic masturbation.He smiled to himself and finished his shower. He walked out with the blue terry cloth.
