The clinic's sterile environment is a stark contrast to the heat building between the doctor and his patient. The doctor's large hands, usually used to heal, now tease and explore the patient's most intimate area. He rolls the testicles gently, feeling their weight, tracing the veins that throb with desire. The patient's cock twitches, straining against the doctor's touch, begging for more. The air is thick with anticipation, the only sound the soft moans of the patient, his breath ragged with arousal.
