The young twink hesitates as the doctor guides his hand to the bulge in his pants, feeling the throbbing cock beneath. The doctor, with a reassuring smile, whispers, "It's okay, let's explore this together." He unzips the twink's pants, revealing his hard, uncut cock. The doctor takes it in his mouth, swirling his tongue around the head, teaching the boy the pleasure of gay oral sex. The twink, tentatively at first, then with growing enthusiasm, begins to reciprocate, taking the doctor's thick, veined cock into his mouth, learning the art of gay sucking.
