FSDSS-820 Rin Yamitsu, a big-breasted part-time worker who was teased by the convenience store manager she hates and was made into a sloppy and sensitive premature ejaculator by having her sticky nipples tortured during her part-time job.

Rin has just come out from the countryside. - Plain and shy. - She is not easily pushy and cannot resist when her superiors force her to do something. - One day, I saw a notice recruiting part-time workers at a nearby convenience store, and as I was hesitant, the store manager approached me and I was hired. - Even in a convenience store uniform, she can't hide her big breasts and falls into the store manager's trap. - When Rin goes to a convenience store, the manager she hates does naughty things to her, and even though she knows it, she can't quit her part-time job.What is the reason? - "I can't just touch them myself, these nipples have turned into lustful nipples."
