A convenience store run by a couple. I ended up working part-time for a few months until I graduated. His wife, Mina, who works part-time as a helper, always works with him on shifts and kindly teaches him. She seems to be on good terms with the store manager's husband, but... "Hey... isn't it okay to be a married woman?" Even during my part-time job, I fell into Mina's swamp because of her rude behavior and fetish face... I realized that no matter how much I cum inside her, we won't be able to bond. But... I was doing part-time shifts for 5 hours until I graduated, and I ended up cumming inside me until all the sperm ran out.
