A perverted female doctor conducts health checkups on female students, obsessively focusing on nipple stimulation. Techniques include pressing, flicking, pinching, pulling, and licking with a sharpened tongue tip. Tools such as measuring tape, calipers, nipple suction devices, and low-frequency stimulators are featured. There are also nipple-to-nipple rubbing, foot-based nipple play, and climax induced solely through nipple stimulation, sending the patients into ecstatic frenzy with exaggerated ahegao-style expressions.
