son should have been feeding on that dad's cum load,, all that testosterone, nutrients, protein going to waste. he's trying to build muscle but he wasted that muscle building seed. hate that but the sex was good with them.
I don't think that was the first time he sucked a cock. When did the younger guy cum if he the older guy has been in porn long enough to know to spit it out so we can see. I'm not convinced he unloaded .
