Just Once At A Party

Last weekend at a law school party, I had sex with my classmate Mark on the floor of his dorm room. We barely knew each other but after some drinks and flirting, he suggested we go to his room. We locked the door and undressed quickly. He entered me without warning, thrusting hard from the start. I felt so full and wet, his cock sliding deep inside me over and over until we both came with harsh grunts.
