To earn money for her favorite band and dates with her boyfriend, Tsukumo works hard at a convenience store. However, the store manager always bothers her and enjoys himself alone as a perverted old man from the Showa era. One day, while going to work, she catches the manager masturbating in the back room… The shock of seeing something she didn't want to see was immense, but more than that, Tsukumo's heart was shaken by how big the manager's penis was. Falling prey to the manager's poisonous fangs, Tsukumo becomes a dick addict... She gives head to the manager's huge cock even with her boyfriend nearby. The more shifts she inserts, the more the uniformed female part-timer's greedy pussy wants it… While refilling drinks, if he doesn't refill his balls with semen, the semen stock won't keep up with this age-gap intercourse.
