The prospect of being caught and the time limit will spur passion and make for an unforgettable impromptu sex.
The hardest part is choosing the right store. It has to be big enough, with several fitting rooms. Not too busy so that you won’t be asked to leave the fitting room after five minutes. But also not too empty, so you don’t attract unwanted attention. And you should look for fitting booths with doors, not curtains.
Take more items from the racks and go to the fitting room. Better do it separately from each other to avoid suspicion. Take it away! You have little time for the action.
Have oral sex or choose a standing position where you don’t have to lean against walls, for example, doggy style.
Avoid making noise and getting caught and enjoy the adrenaline in your blood.
