Satomi's mother-in-law and Yuichi, a college student, whose husband lives in a house where they are assigned overseas. Satomi witnessed the erection penis of her sleeping son one day. She lives long away from her husband and is drawn into the penis of her hard and standing son and finally crosses the line. Satomi devours a hard and pulsing penis. I can't stop my lustful life alone in a house where my husband is absent.
