Keita lives alone away from his parents. One day, he receives a phone call from his mother, Yukine, for the first time in a while. "Tomorrow... your father is away on a business trip, so why don't you come over?" (My mother wants to have sex with me!) And then I come home for the first time in a few years... Keita who overlaps Yukine and skin as soon as I open the front door. Yukine who climaxes many times after a long absence. Of course, the day can't end with just that sex.
