Riho wants her to work more shifts to buy a date with her boyfriend and a birthday present, but the unscrupulous store manager will increase her hourly wage if she fucks her. Of course, Fujimori refuses, but the manager says, "It's a waste to have a big increase in hourly wages just for one time." However, after that, the erotic act escalated by luring Fujimori with sweet words of salary increase. At first, it was a sex processing business that I started reluctantly, but at some point I felt pleasure in the act with the store manager and became euphoric.
