Two scenarios come to mind:
1. Two providers, one giving a bj* while the other kneels behind me, enthusiastically eating my butt/perineum/beanbag.
2. Two providers (one a beautiful trans girl). 69 with the first girl.. maybe a mix of 69 and facesitting.. while the other young lady gives me some nice deep strokes in my ass, leading up to a good pounding. I suppose the 2nd could just be wearing a strap-on and doing the same.
yeah.. that sounds nice lol
