OBA-321 Michika Yagi, a married woman who is drowning in sex by inviting saffle to her husband's absence

Michika, her son and her husband are going to a concert of the popular idol group “Puri Puri Princess Z” this year. The night before, while looking forward to the concert, when I was dancing a popular song of Puri Puri Princess Z with my son, Michika got a phone call. The owner of the phone was Kenichi, a younger sex friend I met at a part-time job. And on the day of the concert, Michika used a false illness to break the promise between her son and her husband and brought Kenichi to a house where no one was there.
