stepbrotherson 

The unfortunate relationship between a man and a child fathered by HIS father after the SON marries that father’s ex-girlfriend. The child would be BOTH the SON’s “brother” AND his “step-son”. Originating in Texas!

I’m going to visit my Son and see my LAST Son, or his StepBrotherSon.

Similar to Eskimo Brothers, when 2 dudes fuck the same girl, but she is black.

That's kinda cool, but still pretty fucking gross man.
