Makoto, a hostess at a boob pub, has a bright and cheerful personality and, although her breasts are small, her nipples are super sensitive. When she gets played with, she gets an instant erection, drools, writhes, and transforms into a naughty girl. And once she gets going, she starts providing excessive service in pursuit of pleasure herself. In a boob pub full of big boobs, a small-breasted girl uses her eroticism as a weapon and fights hard to become No. 1!
