Wife’s Lies

After over 10 years my wife and I had a big argument about her being out late and drinking.
She was drunk but not hammered, she became really angry and started making fun of me, in a sexual way. Making fun of how I think I’m a great lover and al, hahaha! Then she starts up, she starts telling me about all these guys she has been with, even after we started seeing each other. I was crushed as she told me about how she continued fucking her FWB with a “bigger cock” after we started having sex. Said she wasn’t giving that up until she was sure she had me. I was dumbfounded and it got worse. She was still seeing him while we were engaged. She then said she had recently had sex with a guy from a club. I just asked how recent and she stumbled a bit and said “I just fucked him in his car before I left the bar, again. Oh yeah, I fucked him last week too.
She was losing steam and I helped her to bed, in the back of my mind thinking she was making all this up, just drunk and mad.
Then I helped her out of her jeans, her panties didn’t lie. I actually felt them.
She was loaded up with someone’s cum.
I left the room and cried as I felt my penis stiffen, I stroked it for a bit and just shuddered as I came picturing her fucking who ever she wants. I think I have been a fool.
