Otowa Mirei, a high school girl who wants to be fucked up by an older man

Soon after my first experience. Mirei has a desire to be messed up by a man. It was my first experience. Sex with a cram school instructor that was completed only once. That's when I learned to cum. She couldn't forget the pleasure she felt at the time and then spent her days in agony... One day, I see a post from a middle-aged man on a message board. Although he was a bit worried, he moved to Tokyo while taking the exam and decided to meet his first man... An innocent G-cup girl who grew up in the countryside decides to move to Tokyo!! Is it awaiting her to fulfill her curiosity? Or is it a trap for the evil desires of middle-aged men?
