Daphne

I never forget that Saturday night. It was about two years ago. I was at Leo's warehouse with an old buddy, Jerry.
Leo's an importer of sex toys. Not just the plain vanilla stuff, but real kinky stuff too - if you want to get a dildo with electrodes built-in and a high-voltage power supply so you can light someone up, Leo's your guy. Compared to some of his wares, that's pretty tame.
As a promotional gimmick, he has a show practically every weekend in an unused section of his warehouse - he calls them 'product demonstrations'- where the attendees are encouraged to try his products on a live 'model.'
Leo's 'models' are co-eds that he recruits from the local University.
He somehow persuades them to strip naked and then allow themselves to be tied up so they are helpless to prevent dozens of perfect strangers from assaulting them with dildoes, vibrators, and other toys, some pleasurable, some not.
