Cute rookie office worker Chika Momoi has a serious problem: her breasts are so sensitive that even brushing against something in the office makes her moan. Once the people around her notice, her perverted department head targets her for nipple training. He ambushes her while she is wearing translucent silicone nipple covers for the crowded train ride home, tears them off, and relentlessly pinches, licks, and sucks her pink nipples. He drags her into a reception room and increases the suction on a pair of nipple pumps until she cums repeatedly and starts playing with her nipples herself. With them still rock hard, he fucks her smooth-shaven, plump pink pussy and creampies her, then forces her to deep-throat his cock clean.
