I guess I have had something similar. My first long term girlfriend used to fuck other guys, I was no angel either:-) anyway we would get drunk and it would come out that she had fucked someone. We would argue, she would say she was sorry, we would drink more and I would make her tell me every detail. Who he was, how big, if she I joyed it and if she came etc. anyway I would get incredibly turned on, forgive her and end up having great sex. We just kept on doing this
It is only recently that I realise my first girlfriend made me a cuck and now I so want my wife to cuck me. Would love to hear more about you and your wife.
