kuramoto snow noise, a relative's snow sound lady who secretly seduces me

It's been three years since my uncle died in a traffic accident. In the summer vacation, I came to a house in the back of the mountain where my father and Aunt Yukine live. It's been a long time since I met Aunt Snow Sound, but it hasn't changed at all... No, it has become more beautiful than before. The big boobs of the sweaty, snow-sounding aunt were shining so brightly in the sunset that I was irritated. That night, I saw something I shouldn't have seen. Aunt Snow Sound and Father are looking for each other in the sweat.
