So I've been married to my wife for 13 years. As long as I've known her she's never been skinny. Probably 5'5" and about 180 lbs when I met her. I was totally ok with that. I've never been attracted to skinny women. She had a daughter already when we met and we had a son a year after we got married. At her heaviest she was probably 230. I say probably in both cases because she would never tell me her weight.
Well, a couple years ago she decided to do something about it. She changed her eating habits and started working out 3-4 times a week. As of a year ago, she is at 145 lbs. She's still thick but fit. Perfectly round bubble butt, muscular thighs. Her tits went from an E, down to a c cup. She's smoking hot. I've never been ashamed of her. I've always found her hot.
When she was heavier she had no sex drive. It was more a chore. Now that shes thinner, she has a huge sex drive. She likes being naked anytime she can. She actually goes bottomless in the house. Just a tank top.
She also jokes about her work out boyfriend. Some guy she works out with. About 4 months ago, she came home really late. She works out in the evening after work and is usually home by 8. This time it was 10:30.
I asked why she was late. She said I probably didn't want to know. I was joking and said, "You finally stop teasing your boyfriend." She said, "Yup." I said, "Wait. For real?" She said, "Yep. We've been flirting for months. I caved and let him fuck me."
Now I know I should be pissed but I'm not. It turned me on. I had never seen this guy and I had a hard on growing thinking about her on all fours taking this guys dick.
