VAGU-295 Aroused by the sight of his mother-in-law, Mizuki Kaori, who was trapped and could no longer hold it in, he repeatedly climaxed inside her and continued their affair, unable to stop himself.

Kaori married Yuichi, a much older divorced man, several years ago, and they live together with Yuichi’s son from a previous marriage, Kota. While Kaori feels happy with their everyday life, Kota resents her for acting like his mother. Wanting to humiliate Kaori, Kota secretly gives her a diuretic and pretends it was an accident, trapping himself in the room with her. Unaware of what happened, Kaori desperately tries to hold it in as the urge grows stronger, but she can no longer endure it and loses control in front of Kota. Excited by Kaori’s embarrassed state, Kota lunges at her and continues to act in a forceful and inappropriate way.
