I don’t think **** is supposed to be a how-to, friend.

And now OP has hopefully learned that **** is not real life… I hope your girlfriend was not injured! Seriously, just because you see something in a video, movie, or TV does not mean that you can do that. Those **** actors who do that probably spend much of their time working out and building strength and coordination…

You must have some hang time! If you can complete the act during a jump, that's definitely too quick. The only way to safely act out your fantasy is on a plane (with neither of you piloting). You can do that with a woman of any size.

Doesn't matter had sex!

Save it for the bed, old timer.

There was a Mythbusters episode where they were testing to see if someone could get a car up on just two wheels and drive it around, like they do in the movies. They determined that a novice could not do it a on first try and it requires a trained stunt driver... which is what they use in the movies, of course. I imagine this same logic can be applied to these kinds of exotic positions in **** movies

you gotta utilize a wall !
