I have been married for 10 years.

I have been sleeping with my wife's brother for 8. He comes over as soon as she goes to work and pounds my ass till it bleeds. Sometimes I finger my own asshole while I'm fucking her and I think of him.

I'm in love with her brother and he loves me but we're both married.

When he fucks my ass, I am in heaven. I always suck his cock after he fucks my ass. If its a little dirty, I turns me on even more. I come buckets when he fucks me.
