Miyuki, a mother who works for cooking before her husband returns home. The only son appears there and stares at his mother with a fixed look. Miyuki is just confused by her son who asks for sexual intercourse as a matter of course, "Mom, let's do it today." In the past, he had just provided his body to his son due to several mistakes, and after that, he was relentlessly asked to have sex. Miyuki accepts her son's cock without forgetting a harder thrust than her husband, while staring at her son who asks for sexual intercourse before her husband sleeps instead of keeping it secret from her husband. I couldn't live without my son Ji-Po.
