I get along well with my wife and have a happy family. But I have a secret that I can't tell my wife... That is, I am having an affair with a friend of my wife's. At first, it was just for fun, but she is getting more and more serious, and recently her feelings for me have escalated, and she comes into my house whether my wife is there or not and seduces me with sex when I'm nearby! My lover, who is a sex-crazed monster with an insatiable libido, is crazy and imprisons me in his house and cums over and over again!
