2 Nights 3 Days of Sweaty Sex with My Swimsuit-Clad Sister-in-Law When the Breaker Broke and the Heat Made Her Horny—The Scorching Mating That Drowns Out the Cicadas and Summer Heat— Maki Tomoda
Three years into her marriage with a younger husband, married woman Maki is spending the summer living together with her brother-in-law, who has just returned from an overseas transfer, and her husband. Shortly after her brother-in-law comes home, her husband is suddenly sent on a business trip, leaving Maki alone with her brother-in-law. To cope with the scorching heat, Maki changes into a swimsuit and begins doing housework. However, during cleaning, the circuit breaker breaks down, and repairs will take a week. Overwhelmed by the sweltering heat and discomfort, Maki sets up a bucket on the porch and starts bathing in her swimsuit—only to be accidentally seen by her brother-in-law.
