Dr. Desires, a seasoned gay doctor, welcomes a shy twink for his first-ever physical exam. The young man, nervous but curious, strips down as the doctor's eager eyes rove over his smooth, toned body. The exam begins innocently enough, but the doctor's true intentions become clear as he lingers on the twink's growing erection. He suggests a "penis test," and the twink, hesitant but excited, agrees. The doctor's professional demeanor cracks as he handles the twink's throbbing cock, stroking it to full hardness before sucking it deep into his mouth.
