Nettaiya Sayuki Kano

The midsummer sun blazes down on Mikito, an older brother-in-law frustrated by his unsuccessful job search. His pent-up anger is directed at Sayuki, his younger brother's wife who lives with them, and when the family is away, Mikito forcefully rapes her. Sweat-drenched, lustful sex. Sayuki resists, but she succumbs to Mikito's desire, who attacks her whenever he sees an opening, and she is soon thrust into him repeatedly, climaxing many times while drenched in sweat.
