Surrounded by her husband and son Shuichi, Reiko lives a happy life. One night, Reiko and Shuichi receive a call that their husband had an accident. Fortunately, my husband was only injured, but he was ordered to rest at home. And a few days later, Reiko, who was pestered by her husband who was in estrus with his wife who took care of herself who could not move, accepts her husband's cock at the woman on top posture which she usually does not do. Reiko can't stop cowgirl because of the pleasure of riding a man.
