Is there some scene that is not shown that I'm missing here? He guides his hand toward him but I don't remember seeing her shove it in his pants or anything too crazy. The act was implied and while he was being super creepy it's not like the actors were actually performing the act. And not like we saw anything crazy inappropriate outside of the implied message.

They simply switched hands for the 'contact' shots. And with two shots of each face, what the man says can be filmed unheard by the girl.
