The bi-curious student, hungry for new experiences, finds himself in a room with his trainer, who has other plans than academics. She presents him with a strapon, explaining the art of pegging and domination. As she takes control, he feels the cold, rubbery phallus press against his virgin asshole, stretching it wide as she pushes in, making him moan and squirm in a mix of pain and pleasure. His bisexual fantasies are now a reality, and he's eager to explore this new world of submission and humiliation.
