I have a twist on this fetish. I have my girlfriend wear a small dress, do her makeup and hair, and put on 6 1/2" stilettos (no platform). I get behind her car, she puts it in reverse, and lets up the brake. I use my strength to hold her in place. It's easy at idle so she begins to press down on the gas. She puts the tip of the heel where the pedal starts (at the floor) and uses her calves to arch her feet pressing the gas down. The contest is to see if I can hold her past the point where she can arch, as the heels limit how far she can get the gas down.
So far I've been able to hold her but her feet are getting more flexible and I've been struggling harder and harder. I have thickly muscled powerful legs that I work hard at the gym but she's catching up. I'll need to get her some 7" heels if I can't outpace her. I get turned on by the struggle of wills and strength (her calf will cramp up and she fights through it). Mainly, though, I get off by looking down, over her shoulder, at her foot arching high over that tall stiletto.
At the same time, she has a vibrator inside of her that I remotely control, and is using an external vibrator on herself. She orgasms over and over during these 40 minute sessions, arching her feet to the extreme each time (can't control herself at these moments). It's up to me to do my part and hold her at those times. Eventually, I orgasm hard covering the back of her car with cum.
I'll bet you've never heard this one before!
Here's what it looks like:
