Riko, a gentle and sexy busty girl who came to Tokyo from the countryside to work in the sex industry, was always unable to refuse the requests of customers and ended up being fired from the shop for excessive service. "This time I'll definitely refuse!" Riko resolves this every time she moves to a new shop, but in the end she gives in to the customers' requests and does things she shouldn't. She touches reckless customers, puts her fingers in, forces them to jerk off, has raw sex, and has sex with them... she can do whatever she wants! Soaplands, boob pubs, men's massage parlors, delivery health... after being fired, she goes on a full course tour of sex establishments!!
