[JUQ-150] The plot to turn the daughter-in-law into the father-in-law’s mistress

An incestuous sex movie by Nao Jinguuji… Koichi is the son of the owner of a famous company, Tabuchi.

Of course, having such a beautiful girl as his wife makes Koichi happy. Nao doesn’t want to, but in front of Tabuchi’s power, she has to agree. He also requires Nao not to fuck anyone, including Koichi, until marriage. A year later, Koichi and Nao finally get married. That night, Koichi is eager to “consummate the marriage” with the beautiful bride, but because he is too nervous, he cannot get an erection.
