Pigly,
My brilliant deduction skills tell me one of two things that make this penetration possible:
1. The stomach area of the Woman is not real.

2. Or the Slaves hand and arm fold up like a tri-fold beach chair.

In any case, this chick definitely ranks up there as one of the best. Aside from the DEEEEEEEEP fisting, did any one notice the way the Slave was twisting his hand and arm(I don't believe I just said that) inside her and with drawling them?
GREAT FUCKING VID DUDE!!!!!!!! Keep them coming.
Later,
