Mason has an idea

As you cannot get it up anymore. You hear your best friend as he is about to say something.

"I can go another round you see? I'm hard again. And if my cock is not enough we can always call more guys here"

Emma seems to get even happier once your best friend mentions more guys. She looks at you waiting for an answer.

You do not want to admit it but you kinda wanted to see her get fucked more. But you don't want to lose her either. You start to think this through clearly before answering.
