When my wife was pregnant and visiting her parents... I thought she must be having a hard time, so my wife's sister, Rena, suddenly showed up at our house. As I was casually taking a bath, Rena came in saying, "Let me wash your back," and I was shocked!! Being alone with her made my heart race, and I involuntarily got an erection... Seeing this, Rena started touching my penis with lewd hands!! It turns out that Rena isn't getting along with her husband and came to our house to satisfy her sexual frustrations!
