Yes, already back the they faked some of the cumshots, esp. if the guy didn't shoot a proper load (Randy West could have used this faking once in a while)
About the cumshots in vintage movies, it is my opinion that when you don't see it coming out from a cock is probably a fake. I don't have seen so much of Gabriel Pontello to know what is his typical cumshot but this is so inconsistent and watery. Maybe it is honey or milk.
the blonde in the scene @ 14:40 would have to be one of the hottest of scene on this whole website! veeeeeeeeeeeeeeeeeeeerrrry sexy - top rate!
