Okay Alex, I'll bite. Let's say your wife has been getting dick down by some 11" x 8" stud, who is definitely NOT you---since the second week of marriage...and she got preggers, and you, being the happy hubby excepted like it was your own. It was a nice light skinned boy, with blue eyes. But, up until last week, you found out it wasn't...
Of course a judge probably will say, "feed him until he looks like you"
Not only was she having her back broke by a well hung dude, but she made you a a unwitting cuckhold.
