It's hit and miss.
The best thing is to ask the MPA if they like duos, they seem to have a preference on who they do it with. Some will do it, but aren't into it which makes it a waste of money. The girls seem to be in the mood one season and not in the mood another so personal research is your best bet. Ask you favourite MPA, you might be pleasently surprised.
I think Melissa at Platinum is into it, but it was a while ago and I can't remember if that is the correct name. I remeber that it was a canadian girl with ample breasts and hips for sure.
Let me know if you find a good current one. I love a good duo.
