We are looking for friendly father-daughter couples online with a prize of 1 million yen. The five father-daughter pairs who responded to the call will receive a gift of massage from the daughters! The condition of the 1 million yen that the fathers don't know is that they will ejaculate with "sumata" (intercrural sex)! The daughters, who are after the money, take a sumata training course and try it out! You might think that a piece of plastic wrap will be enough, but this wrap actually melts when rubbed!!
