Mother Miyuki who works for cooking before her husband comes home. Then the only son appears and looks at her mother with her fixed eyes. "Mother, let's do it today," Miyuki is just confused by her son who asks for sexual intercourse as a matter of course. In the past, she made several mistakes and offered her own body to her son. Instead of keeping it a secret from her husband, she stares at her son who asks for sexual intercourse in front of her husband's sleep, but accepts her son's cock without forgetting the thrust that is stronger than her husband's. Miyuki is exhausted... She could no longer live without her son's cock.
