What yaron58 said. It's not really his son.
And the vid Yaron posted is funny as hell. He hands the cut guy who's pretending to be his son some lube and says smething like 'he needs lube because I made the mistake of having him cut.'
The MILF step mom is like 'that wasn't my fault, I wasn't around when he was born. Anyway it's kind of fun having one of each.'
