JUL-416 The teenage son and the lustful stepmother live together in the same house, and what happens has happened.

The Japanese archipelago is experiencing a record warm winter this year. Takayuki returned to his parents' home during the winter break. Usually, the weather is cold enough to shiver, but this year is completely different. Aishichi's in-laws live in the house, but when she came back home, Aishichi had already packed away her fall clothes early and was cleaning the room, sweating in her winter knitted sweater. She puffed her chest out of the snug-fitting knitted sweater and was sweating under her armpits and neck. Seeing his mother-in-law like that, Takayuki couldn't contain his emotions.
