It's somewhat difficult to fully accomplish with a man's hands perhaps. I have somebody that had tried repeatedly with me, with almost success, but the very end going in part just won't happen. Even with lots of lube and I'm way fully turned on to the point of squirting after several orgasms, I think hand size might be what really matters. I have watched fisting porn, and two girls can really maybe be the real answer? So maybe you could do a three way? Or yes, there has got to be a provider who can with enough search!  

I love it.  PM me.
