After several years of marriage to her husband 'Tetsu'... wife 'Yukoko' still can't close the distance with her stepson 'Manabu'. This year, she decided to use Tetsu's summer vacation to return to her hometown in hopes of becoming closer. However, for Yukoko, who is used to city life, living in a wooden house without air conditioning was unbearably hot. ＜Sweat trickling down her neck＞＜Beads of sweat on her cleavage＞＜Armpit sweat overflowing＞ The obscene sweat covering her entire body drove Manabu mad, and he began to see Yukoko not as a mother but as a woman.
