Yoi ga Sameru Sono Mae ni

Mitsuru, a divorced woman, is drinking at home with her son Youichi and his friend Kageyama-kun. When Youichi gets drunk and falls asleep, Mitsuru, who is also tipsy, finds herself in a compromising situation when Kageyama-kun makes a move on her right in front of her unconscious son.

What follows is a spontaneous and lewd encounter between the two, happening just inches away from Youichi. As Kageyama-kun takes advantage of the situation, Mitsuru gives in to her desires, leading to a passionate and unprotected encounter that ends with a creampie. All the while, her son remains asleep, unaware of the forbidden act taking place before him.
