MDYD-975 Tropical Night Tomino Miho

My sister-in-law, Miho, was kind to my brother-in-law who had a narrow shoulder because he didn't get a good job. On a tropical night in the middle of summer, my brother-in-law who peeked at her younger brother and his wife's activities unbearably commits Miho. What is Miho's reaction when he decides to leave home because he can't stand his own mistakes? A man and a woman who meet in a sweaty night drown in a dense love! ! !
