The doctor's office transforms into a den of carnal desires as the grizzled bear of a man, his step-son, and a hungry patient indulge in a heated, passionate threesome. The room echoes with the sounds of skin slapping against skin, the wet suction of hungry mouths, and the grunts of pleasure as they explore each other's bodies. The doctor's thick, uncut cock stretches the patient's eager mouth, while his step-son's slim, smooth body writhes with pleasure, sandwiching the patient between them. The air is thick with the scent of sweat, precum, and the faint antiseptic tang of the clinic.
