21-year-old Suzu is a shy and innocent girl who has never dated or even spoken to a man before. Currently striving to reclaim her youth, she's working hard to leave behind her dull office lady lifestyle and build a new life overseas. However, with no boyfriend for the past year, she's been left frustrated and restless, her 1M-sized sensitive breasts craving attention. Lately, her body has grown so sensitive that she can climax simply from her nipples rubbing against the inside of her bra. What kind of situation she now finds herself in is anyone's guess.
