Don't care which position I'd be, I just wanna be there.

Guy on top must surely be trying out each face in turn to see which is the most 'comfortable'. That would be the ideal guy to replace by self, though I'm sure the two on either side are not just gonna sit there and wait till a bum is plumped down onto their own visage - and they can start to lick, lick, lick. Why don't those two take turns at sitting on each other's face?
