I am still laughing at after reading it hours ago.

I've read before about such practices!

This is BS of course. The girl supposedly kept doing his son. I don't think a provider would be that given even if it were some famous guys such as Will Smith and his son Jade if he was 18 as an example.
One thing I know for sure is this guy is really good at writing porn and could make a living from it haha.  

I however have read before of such practices in some countries. In the Caribbean region of Columbia , some Afrocolumbian fathers do this. I went online to try to find that same information but wasn't that lucky.  
I found a YouTube video of a Nicaraguan father doing this. I've attached the video here.
