I had to babysit my wife's bull's brats

I have never been a cuckold.
Six months ago I married a really hot woman 15 years younger than me - 22. I thought everything
was gypped, but the sex wasn't as much as I hoped.
On the night before Thanksgiving I came home and found this ghetto type black man fucking my wife.
He didn't stop and he left just pretending I wasn't even there. My wife kind of apologized, but basically said I wasn't good at sex. I was devastated.
I thought we were trying to work through it, but just before noon my wife told me her lover was coming back to fuck her. I couldn't do anything about it.

He pulled up in a really beat up minivan. He came in and told us I had to take care of four of his k**s while he was there/ I said no way, but was eventually forced to. They were 5 k**s from 5 to 11 and all had different mothers, and all looked mixed.

I took them to MacDonald's and then to the Jungle, and then to a movie. I was told not to come back until they called me.
It was the most humiliating thing in my life. I said never again, but I have a bad feeling.

I don't want to be a cuckold, I hate cuckold.
