Hiroshi, a brother-in-law with a narrow shoulder, returned to his parents' house after being transferred to a rural area. On a sweltering tropical night, I am fascinated by the sweaty sleeping appearance of my younger brother's wife, Ayumi. Frustrated and lustful, his brother-in-law commits Yumi in the absence of his family. What was Yumi's reaction to him? A dense relationship between a man and a woman who get sweaty on a sleepy night! !! !!
