Humiliate her

Charli paused Addison then hit Input: Addison, you will remove your top then fill your bottoms with sand. You will keep packing sand into the front and back of your bikini bottoms until they can't hold any more. You have no idea why you're doing this, but feeling humiliated in public makes you very horny. The more humiliated you feel, the hornier you'll get."

Charli unpaused Addison.

Addison reached around her to undo her top. She was not sure why she was doing it, but she removed her top. She then went to the beach where the sand was dry, dropped her bikini top, knelt and started stuffing handfuls of sand into her bikini bottoms.

"What the hell are you doin?" asked Charli as she took out her phone and started filming Addison.

"I don't know!" said a freaking out Addison as she kept shoveling sand into her bikini bottoms.

Charli laughed and kept filming and more people gathered around to watch.
