A new office lady at a lingerie maker is relentlessly teased by her boss who fetishizes nipples, developing her sensitive nipples! Pinch, roll, lick... she masturbates her nipples every day to the point where they've become an erogenous zone. Her shy, large breasts are captured in extreme close-up. It's embarrassing but she can't help feeling it... this sensitive OL reaches orgasm multiple times just from her nipples. Detailed recording of the process of becoming addicted to Chikuona without realizing it.
