My sister-in-law, Lisa, is ten years younger than my wife and has always been a tease for as long as I can remember. Whenever my wife is not looking or is not in the same room, her younger sister finds an opportunity to bend over in front of me and show me her breasts and ample cleavage. I have to admit, it is a turn-on and fuel for fantasy when I make love to my wife. It has become a game of sorts for Lisa to display as much of her body to me as she can without getting caught. I have never cheated on my wife and probably never will cheat on my wife. The only woman that I have truly given thoughts about making love to other than my wife is her sister, Lisa. She exudes sensuality and desire whenever we are in the same room. Itís probably just a game to her. I'm sure that's what it is and nothing more.
