My wife did this and it was hot!
Difference was, it was bet she lost, something about our mileage till the next stop and it was not remote.
I’ll try and find the post and do a cut and paste.
Found it.
Returning from a road trip she lost a bet about where a tourist stop was. I said she would have to do something sexy. When we parked at the store I retrieved her workout shorts (very tight spandex) and her vibrator from her bag.
In the car I told her to put it in and the spandex on to keep it in place, then her regular shorts.
We entered the store, which was packed, and wandered around for a while. I could tell when she came because she had to hold on to a shelf.
We were leaving and store security approached, questioning her about feeling ill. She came again and staggered a bit. Security wanted to call an ambulance LOL! I helped her to the car, she was staggering all the time now, and left immediately.
When we were on the road she dropped both pairs of shorts and masturbated furiously with the vibrator until she came at least three times.
