In the privacy of his room, a clothed gay man lets his curiosity lead him to an intense solo exploration. A clear bottle, cool and slick, becomes his unlikely partner. He lubes up, positioning the bottle at his tight, quivering asshole. With a slow, steady push, he dilates himself, gasping as the thick glass fills him. His moans echo as he slides the bottle in and out, feeling his hole stretch wider with each thrust. Caught up in the moment, he doesn't hear the door open. His roommate stands there, shocked and aroused, watching as the bottle disappears into his friend's ass.
