Kazuya is very happy to know that her mother's friend, Mayu, will visit her for the first time after a long time. And on the night we met again, when we went to drink alone... In her intoxication, she both had relations and comforted this woman who was complaining about her husband. They sought desire to fill the loneliness and enjoy secret pleasure. However, Mayu, who is married, tried to avoid feeling guilty about her husband.
