ok, this one is similar to a position my friend made up that he calls the Jackhammer. But the girls legs are up and the man stands up between them and drops down for deep penetration. Could easily be done for MF, FF, MM with strap ons. When my friend does this, the female has pillows to support her and his weight is not completely on the female.
That is the only thing about the piledriver position that I do not care for is that the man who is much heavier normally has all weight on the females back…that would so hurt in real if more than a few mintues..
