Celebrating Our 15th Anniversary

My wife and i recently celebrated our 20th anniversary and went out to dinner just us leaving the kids at home. 2 wonderful boys she has given me. What people my family her family our kids don’t know is how Chris and I got together. We met while out on dates. She was with her fiancée and I was with a girl that I was with for sex. Chris is a gorgeous brunette wears glasses. Has that slutty librarian look going short hair to her shoulders. I pair of Double D tits a slim waist and a nice fat ass. My self and other people have told her that she could easily do porn. I approached her while her fiancé was out smoking a cigarette and left her at the table for 5 minutes. I swooped in gave her my number a kiss on the cheek and she was surprised and what she later told me was impressed with my confidence. She took a few days to think it over got into an argument with him on those days and she called me up and asked if i was serious about drinks. A couple of hours later we are at a bar and a couple of hours later after leaving the bar I have her on my floor giving her rug burns on her lower back from the pounding i gave her. She let me get close with her and even though her wedding was being planned she had other ideas. She was so nervous to end it she didn’t really know how to let him down. The closer it got the more sex we where having. She often disappeared for hours ghosting him until we finished i always finished inside her no rubbers where ever used. She liked going home full and said she liked the feeling of it running out down her leg. She often say there and as it leaked she would use her fingers to wipe it off then eat it. This always got me hot and we would fuck again. It was obvious she wanted to end it with her husband to be. So I took it upon myself to send him a letter back then that how you remained anonymous. I basically told him that your future wife has been getting fucked in this particular parking lot after her workout. Because I wrote the letter I told him what time she would be there I labeled it a concerned friend. I just made sure that Chris would be butt ass naked. I took my time ate her out usually she would leave her panties and shirt on. Nope I had her on all 4s ramming her when the door to her old table flung open and he looked in. The sight he was was me behind her I was in her ass he tits where swaying back and forth form the thrust. She sat up tits out line on her ass he of all things started to cry. I got dressed she got dressed. I left them there and a few hours later she came back to me and said it was over she needed a place to stay. A year later she has a ring on her finger. We blink and almost 20 years go by and she still has no idea I sent the letter. Best thing I ever did
