It helps to have the two girls being somewhat interested sexually in each other or you just have a situation where they are friends and both happen to want to fuck the guy. That is a bit awkward in the moment because each of them is just sort of waiting their turn to get fucked and it's all your show. If they are both turned on by each other then the atmosphere can be fun and everybody laughing and having a good time. If everybody can relax and just make each other cum as much as possible, that's best case scenario for it not to be awkward later.
