My friend's mother

Yuji comes to stay at a friend's house. There was a reason why he went to stay at a friend's house that he wasn't particularly close to. This is because I was curious about Sana, my beautiful and beautiful friend's mother. On this day, I was just peeking at Sana's butt and chest at the edge of my vision, but as I woke up at night and headed to the bathroom, I saw Sana masturbating in the bedroom, and took a picture of the whole thing on my cell phone. The next day, Sana shows him a video of him masturbating and climaxing his relationship...
