Kinda like asking how many angels can fap on the head of a pin! That said . . .

One of my all-time fave threesomes is with Kelly Wells and Sasha Knox from "Cumfart Cocktails 4."  It's Kelly at her nastiest, especially talking.  I may also be partial to it since I have been fortunate enough to have spent some quality time with both of these lovelies, just not together.  And apparently, that's not going to happen since when I brought that scene up to Sasha last year, she expressed a clear disinterest in working with Kelly again.  Must have made a hell of an impression, since the scene was shot almost 10 years ago!

I am into 3somes but more the MFM type

I like Allison Miller for her moves the scene is not overacted and everyone moves are on cue.

I hear you on getting a few ideas..related question is would you share a link to your prep video with your threesome partners? I ask because I've become a fan of 3somes, and always want to keep it fresh, even if the other two are my repeats for a 3 some.
