Incest: A mother who climaxed 96 times in 24 hours

Keita lives alone, leaving his parents. One day, my mother Yukine receives a call for the first time in a while. "Tomorrow... your dad will be leaving the house on a business trip so why don't you come and visit us?" After hearing this story, Keita quickly understands her mother's feelings. (Mom wants to have sex with me!!) And then she returns home for the first time in a few years... As soon as she opens the front door, Keita begins to overlap with Yukine. Yukine climaxes many times after having sex after a long time. Of course, that sex alone wouldn't end today...
