I can't stop cowgirling...

Reiko lives a happy life surrounded by her husband and son Shuichi. One night, Reiko and Shuichi receive a call saying, ``My husband has been in an accident.'' Fortunately, her husband escaped with only injuries, but was ordered to rest at home. And then, a few days later, Reiko accepts his cock in a cowgirl position, something she has never done before, as her husband, who is in heat, urges his wife to take good care of him even though he is unable to move. Reiko becomes unable to stop riding the cowgirl position due to the pleasure of riding a man in a slutty position.
