Tropical Night, Nanako Mori, MDYD-849

Uncle Takuji, burdened by work and estrangement from his family, harbors deep resentment. He secretly watches his sister-in-law, Nanako, sleeping soundly on summer nights, her skin glistening with moisture. While her husband is away on a business trip, he violates Nanako in secret, engaging in intense, sweaty sex. On the night before his brother's return, Takuji, determined to leave home, makes one last plea for Nanako's body.
