"I wanted to ask you a few things... Tell me why Hikari and Ria are acting the way they are." Kanon Miyashita, a classmate, suddenly shows up at the house. She is part of the close-knit group that includes Kuroda-san and Nishizono-san. "Do it with me, too. It feels way better than with Hikari or Ria." She makes a sudden advance; I try to refuse, but I can't quite bring myself to say no... "I'll make sure it feels really good for you..." I find myself swept along, letting things happen to me. "No ejaculating for the next week, okay? You can hold it in, right?" *Note (Please read the following carefully): ・There are absolutely no erotic scenes involving Hikari Kuroda or Ria Nishizono in this story. ・It contains elements of "teaching a lesson" (breaking someone's resistance); it is not a scenario of total female dominance. ・It does not develop into a harem story.
