Hi,
today I would like to introduce my piledriver position improvement. I've been thinking a long time how to make this position even better.

The major thing consists in SUPPORTING GIRL'S THIGHS during this position. The girl has to pull her legs a little back as usual (only little) and you give a support for her things or entire legs, but mostly the thighs.

In other words to let thighs relax on some kind of support.
Read ahead, I will try to write detailed description.

The best solution is to use a "slant" gym bench for the entire piledriver position and a pair of 2 another smaller benches (each for one thigh by the sides of the main bench) for supporting the girl's thighs or whole legs.
I provided links to illustrate my idea:

1.:This kind of main bench for the position (with butt high up in sharp degree)

Or this bench

2.:
And this bench for supporting the thighs, each on one side besides the main bench in a V shape position

Or this one

SETUP OF THE BENCHES: Girl laying on the big slant bench with ass high up, with her legs pulled a bit back towards her head (thighs a bit less then perpendicular=I mean knees lower then thighs) and thighs rested on the side benches in V-shaper style from top view)

So 3 most important things about benches:
1) Relative height to the main bench. They have to support
WHOLE thighs from the downside.
2) Little declination of the side benches down toward her head (only about 20 degrees is fine)
3) The girl's thighs (knees) has to go apart in a "V" shape from the main bench.

ADVANTAGES:

This position let the girl to rest her legs (mostly thighs) on the side benches.
It combines both functional and visual improvement.

1) Rested thighs in described way hepls to extend girl's pelvic bones to make a even bigger gape. The girl can
control this too by pushing on her rested legs thus raising her ass a bit and extending pelvic bones.
It also helps to relax and straighten anal and rectal linings, so you could be able to enter her ass better and more deeper (BEAM).

2) Top view of this position creates a very exciting erotic picture when you can see her rested fleshy thighs and wide open hole (KUK MAL). Its very erotic especially when a girl has a little more flesh on the legs.

Sorry its hard to explain by words, Im also sorry for the length of this comment.

I tried this with my girlfriend in a improvisited simplified
way and it worked great.

So any director going to try this in his movie?
