"What is this smell?" the source of the sweet and sour scent that filled the house was her mother, Ayano. Ayano, who worked hard during the day, seems to have fallen asleep on the sofa as it is. "I kept my socks on... Mom, I'm going to wake up and catch a cold," a mellow scent tickles Toshiya's nostrils as he approaches to wake him up. I want to smell more. As the desire that springs up, Toshiya touches Ayano's sweaty and glossy body.
