HMN-730 Until the convenience store’s condom stock was wiped out… Tempted by a busty part-time worker with a strong sex drive, I kept arranging shifts to meet her in secret. Even after repeated condom-protected encounters, we still weren’t satisfied, and I ended up falling into an affair in the back room. Yuki Koiro

Koiro Yuki, a college student working part-time at a convenience store, falls for the kindness of her manager, Makoto, and confesses her feelings, only to be turned down because he is married. Even so, she cannot give up and keeps pursuing him aggressively, eventually becoming intimate with him. After being told that they should be careful, she intends to use a few condoms from the store, but loses control and keeps getting closer to him, eventually falling into a relationship where they continue their affair without restraint.
