Riho wants more shifts to pay for dates with her boyfriend and to buy a birthday present, but the unscrupulous store manager offers to raise her hourly wage if she gives him a titjob. Naturally, Fujimori refuses, but the manager says, "It would be a waste to do it once, as your hourly wage will increase significantly." Riho ends up giving in and giving him a titjob just once... However, Riho continues to lure Fujimori with sweet words of higher wages, and her erotic acts escalate. At first, she reluctantly starts working as a sex slave, but before she knows it, she finds pleasure in the act with the manager and becomes intoxicated.
