DASS-090 My wife is at home cheating on me with the neighbor with a big dick.

Mizuki and her boyfriend Kazuya, who are about to get married, are a happy couple, but Mizuki has a strong sexual desire and secretly masturbates because her boyfriend's sexual performance does not meet her needs. Kazuya, who has always dreamed of studying abroad, invited Michael, a black man who has taken care of him, to his home, and the three of them began living together. After Mizuki accidentally saw Michael's big penis, she became so worried about it that it exceeded her limits.
