My wife was way wilder than me and had a short affair a couple years into our marriage. Tho I was hurt the idea of her with another guy has become an obsession for me. She later had a one night stand with a barman and now all I do is fantasize about it as I knew what she was wearing down to her underwear. It is literally driving me insane. She’s a very very attractive lady with a very sexy personality and amazing body so I know she could get any guy she wants and when she goes out with friends now I make sure to see everything she is wearing (without her being aware) and hope she comes home late enough that it’s possible she’s hooked up with somebody so I can fantasize about it.
