Here is a fairly simple one for you:

Clamp your nipples and put in a butt plug and a vibrator and go to a place with those massage chairs. Wear a tight pair of short shorts and a crop top - doesn't have to show that much skin if it makes you uncomfortable but a little would be nice.

If you want to make it more painful, wear a tack bra for this too and/or clamp your pussy with pegs.

Now go sit in the massage chair and turn it on for 10 minutes with the vibrator running. Cum if you want - remember you are in public where people might see - but if you can control yourself, feel free to sit there and act like nothing is going on.

The only catch is you have to cum before you take off/out your toys and go home, whether it is in the open, in a restroom, in a fitting room, etc.

Have fun!
