VENX-145 Ayano Kato, a son who loses his mind due to the acrid smell of his mother's sweat when she comes home from her part-time job.

``I wonder what this smell is?'' The source of the sweet and sour scent that filled the house was my mother, Ayano. - Ayano, who had been working hard during the day, seemed tired and fell asleep on the sofa. - ``I left my socks on...Mom, I woke up and I'm going to catch a cold.'' Toshiya approaches to wake him up, but a rich scent tickles his nostrils. - I want to smell it more. - Following his desire, Toshiya touches Ayano's sweaty and glossy body.
