Aya Kokoro stars in the third installment of the new Sensitive Nipples vs. Dark-Faced Gal series. First, she dresses up as a high school girl and uses devilish dirty talk and her long nails to stimulate her nipples while tugging at them. Next, she sneaks into a man's workplace and does a 69 with him while licking his nipples, giving him a handjob and a blowjob. Next, she goes to a laid-off unemployed man's house and watches his adult video while caressing his nipples and inserting them tightly. Finally, she goes to a bar in Shibuya and stimulates his sensitive nipples with ice, pinching, biting, and rubbing them together while giving him a blowjob.
