Ako is a 25-year-old graduate student at National F University and the only daughter of a tatami-shop family in Daimyo-cho, Fukui. She lives with her family and is currently completing a teaching placement at a local middle school. Despite her limited sexual experience, she is incredibly sensitive. The camera lingers over the M-cup breasts bulging from her pale-pink cardigan. Even a light touch to her nipples makes her twitch. Beneath it is a demure white bra, and when her enormous breasts are grabbed and kneaded from behind, her reactions intensify into startlingly high-pitched cries while the two long, heavy breasts sway.
