He refuses

I didn't want anything more to do with any of her friends. I told Sally no. I expected Sally to quit fucking Rod eventually.

Somehow, I felt that was a mistake now. A few days later, Svetlana informed me that Rod had won first place in the contest she mentioned, but refused to tell me anymore than that. It was, apparently, a secret.

When Rod came over to fuck Sally again, I immediately sensed something weird and intimidating about him. He had changed. I couldn't bring myself to voice my displeasure at Svetlana having sex with him. Instead, I simply watched them go at it, silently jerking off. I felt weak and small compared to Rod.

My feelings of inadequacy only grew as Rod continued to come over. I became more and more passive and subservient towards Svetlana, much to her smug enjoyment. We rarely had sex anymore, and I wasn't very good when we did. Eventually, my entire sex life diminished to watching Rod fuck my wife...and jerking off to porn videos starring Rod. Even my dick seemed deflated and withered - I came too quickly when I masturbated. Seeing Rod's cock shamed me, like I was dumb to ever think I was as well hung as him...but I *did* have a big dick...didn't I?
