As the semester progresses, the college boys' sexual encounters become more intense and varied. They explore anal play, with the straight roommate tentatively fingering and then fucking his gay roommate's tight hole. The gay roommate, in turn, teaches his straight roommate the art of giving and receiving blowjobs, their sessions filled with moans and the wet sounds of slurping. They also invite other college boys to join them, their room becoming a hub of gay and straight physical encounters, a far cry from their initial financial arrangement.
