Riko is a soft-spoken, horny J-cup newcomer from the countryside who can never refuse a customer and keeps getting fired for excessive service. She vows to say no at every new workplace, yet once again lets demanding clients touch her, finger her, force her to finish them off, go bare, and have full sex. After being used however they please, she cycles through soaplands, breast bars, men’s spas, and outcall services in a full tour of the sex industry.
