Hiroshi, a brother-in-law who is freeloading at his parents' house due to the difficulty of finding a job. The midsummer heat adds to the humiliation of being shunned by his family and ridiculed by his younger brother. Hiroshi's anger is directed at his beautiful brother's wife, Ai. I sneak a peek at her sweaty sleeping love, the absence of my family, and finally commit. Sweaty rape sex. I can't tell anyone about people's good love, and I'm swallowed by Hiroshi's desires and gradually become obedient.
