When my father got married for the second time at 63 with my aunt (my mother's younger sister) 18 years younger I knew she would cheat on him. What I didn't see comming was that it would be me who would be fucking his wife. She made it pretty clear only a few months after she got married and told me she already had her stability but she needed a man to fuck her regularly without leaving any suspicious. Guess she had it all planned but I'm enjoying it.
