Natsu Aoi, who had been looking for excitement in her sexless married life for nearly two years, was visited by her nephew Hiroshi, who was two years older than her and whom she had Ke'ai since childhood, after running some errands in the neighborhood. After a long absence, Natsu Aoi was flushed and had no time to do anything with her body. Feeling the stiff, erect penis of her nephew Hiroshi, who had become manly, against the excess fat on her waist, she was driven by a woman's sexual urges and sought out her nephew Hiroshi's hard, pointed cock, guiding it deep into her body and accepting it... That night, taking advantage of her husband's absence, Natsu Aoi enjoyed sex with her nephew Hiroshi for the first time in a long time.
