My wife visits friend and I get cuckold.[cuckold] [cuckolds perspective]

Still shocked my wife went to visit friend from college and while there and having some drinks at her place found out the guy hanging out with them was hung like a horse. Her friend made sure to bring jt up apparently multiple times during the evening. Clearly trying to get my wife to hook up with him or atleast check out if true. Later that night after a few more drinks and prying my wife worked up thr nerve and dared him to prove it. Apparently he did not hesitate and dropped his pants revealing a massive cock. After her initial shock she was convinced(not sure it took much) to try to touch it which lead to him taking her to guest room and having her try it out. I woke up to a video the next morning of her on top of him saying she found a guy twice my size and way better in bed. That he had fucked her most of the night and it was absolutely amazing. Also couldny help but notice that he was wearing no protection as she bounced up and down on his massive cock. When she got home much later she let me know she was going to continue to visit him. We had not discussed open marriage at all before this. She said she had to try it after seeing just how big it was. She said she will not turn him down whenever he asks to fuck because it is absolutely amazing sex. Really has reduced my sex life due to her saying I just cant compare to what he has.
