The husband goes to work in the afternoon, the lustful wife Kojima stays home to clean the house. After cleaning, she rewards herself for completing the work, which is masturbation. Coincidentally, while she was masturbating, an office worker came to advertise their company. She was so horny that she couldn't think of anything else but soliciting sex from the employee. Although he was gentle and knowledgeable, from the moment he entered the house he noticed her attractive breasts and legs because they were so attractive and difficult to control. This made him truly happy to see her. She asked for sex and of course the two secretly had sex with each other in the heat of Kojima's young wife.
