I (30M) have came while looking at my wife's (30F) best friend's social media pics many times

Throwaway account to hide any potential of being found out. I met this married lady, we'll call her Suzy, 3 years ago when my wife, call her Shona, was going to school. Suzy looks a lot like my wife Shona. Blonde, curves in the best places, sometimes Suzy has even been barefoot when both married couples hang out and I can't stop staring at her cute toes. I have fantasized about cheating on Shona with Suzy for years especially after finding out she is also struggling with her marriage. So the best I can do is pull up her face online and I get some amazing orgasms just looking at her Instagram selfies, imagining the nastiest things we could do together. I hope one of these days she could drop a hint that she's attracted to me just to boost my confidence.
