In a clandestine clinic rendezvous, two twinks, hungry for new sensations, engage in a taboo medical role-play. The receiver, clad in a crisp white shirt, lies back, legs spread, as his partner, the eager 'doctor', lubricates his fingers and begins to probe his tight hole. But they soon graduate to more unusual tools, inserting and twisting everyday objects, pushing boundaries and moaning in ecstasy as they explore the limits of their gay desires.
