SSNI-443 [Uncensored Leaked] I'm getting wet and blackmailed by my brother-in-law from morning till night... ~The tip of a busty married woman's see-through, clinging blouse~ Okuda Saki

The brother's wife and her husband live in the apartment building run by his parents, along with his brother's younger brother. While his older brother is earnest and dedicated to his work, the younger brother is a quiet, middle-aged NEET who feels strange, sexual feelings for his brother's wife (sister-in-law), Saki. One day, Saki is caught in an evening shower and becomes completely wet. This triggers the younger brother to subject his sister-in-law to a bizarre humiliation. Saki's wet, cold clothes rob him of her body heat and reason, and in this abnormal situation, he suddenly feels his own body becoming hot.
