Mr. Kawakami, who joined as a new part-timer, looks young, but he is 10 years older than me and married.Her husband and her cold war girlfriend go out drinking and hit it off, and we end up having cheating sex without any invitation.After drinking, both of them came to their senses, but once the libido was ignited, they could not control it, and after that they had sex many times.It's not enough to just do it at home, so we secretly overlap our bodies in the store's toilet and backyard.Her part-time jobmate Seojun seems to be starting to notice us, but she still can't cut off her affair with Mr. Kawakami.
