How bout the position I mentioned earlier, it can be adapted to fff, mmf, mmm, mff.
I'm sitting while a girl/guy is standing above my face and another girl/guy is going down on me(or girl is laying across my lap). If its a guy doing the sitting: girl standing over his head, other girl could be reverse riding him or going down on him(same for mmm). Not dp but still nice.
I want triple pen. mouth, pussy and ass. what can I say, I'm greedy.
