Depends if they are going to DP the girl or not.
If they are there's one interesting position I've only seen once or twice.
You have the girl on all fours and her ass sticking out, one guy fucking her in the ass while he's kinda sitting on top of her, then you have the other guy do her regular doggy. So that if you were to look at them from the front, it would look like as if one guy is fucking the other when in fact they are all doing the girl.
confusing i know :dunno:
