My aunt's temptation - the ripe body that mourns my appetite - Chisato Kuwata

In order to care for his depressed nephew, Yasusuke, after his mother's death, Chisato decided to stay at home for a while. But Senri, who was secretly aware of Yasusuke as a man, repeatedly tempted him every day, and each time his crotch was strongly stimulated. One night, Chisato would wash Yasusuke's back. Kosuke can't control his excitement with his mother's naked body. When he saw the crotch between his erected legs, Chisato was smiling and sucking on a meat stick for the first time.
