Dr. Geo Powell's clinic is no ordinary medical facility. Today, a twinkish stepbrother and sister arrive, both curious about their doctor's rumored proclivities. The siblings undress, revealing their lean, smooth bodies, as Dr. Powell examines them. His professional demeanor wavers when he encounters their eagerness and growing erections. The medical instruments become toys of pleasure, as the doctor explores their tight, virgin holes with gloved fingers and throbbing erections. The siblings moan and writhe, their fantasies of gay doctor-patient roleplay unfolding before them.
