Yui, a high school girl who is not good at making friends, only has friends in social games. While playing games in a nearby park, a man she doesn't know invites her out, asking, "I'm collecting retro games. Want to see them?"Yui follows him. When she gets home, she drinks the juice that he gives her, and when he touches her lightly, she squirts a lot and starts seeking his penis. KM Produce Co., Ltd.
