Cute new office worker Chika Momoi has a problem: her breasts are far too sensitive. Even brushing against something at work makes her moan, and once the people around her notice, her sleazy boss starts a nipple-training campaign. He ambushes her as she puts on translucent silicone nipple covers for the crowded train home, tears them away, then pinches, licks, sucks, and toys relentlessly with her pink nipples. In the reception room, suction cups make her cum until she starts playing with her own nipples and climaxing over and over. With them still rock-hard, her bare pink pussy is penetrated and filled with a creampie, followed by a forceful deep-throat cleanup.
