I started working part-time at a convenience store, and Akari, a part-time housewife, was kind to me and taught me a lot of things, and one day when I was getting used to the job, I received a drink from Akari, who said, Thank you for your hard work. If you like this, have a drink♪ and when I finished it, I felt something... My crotch is hot. My girlfriend passed out...When I woke up, Akari was straddling me...I was in pain because I couldn't understand the situation, but she was crazy.
