In the sterile, clinical environment, two naive twinks in briefs are introduced to the world of gay sex by their open-minded doctor. The boys, curious but inexperienced, tentatively touch each other as the doctor watches, his own desire growing. He can't resist joining in, his large cock pushing past the boys' tight holes for the first time. The room echoes with their cries of pleasure as they take turns riding each other, their briefs discarded on the floor, forgotten in the heat of the moment. The doctor's thick load is the final straw, sending the boys over the edge in a explosive first-time finish.
