"Unless you tell us why you're doing this," said Bella.

"If I don't get every woman here to slap my ass, I have to walk home like this," said Shelby.

"Do if we don't slap your ass, you have to walk home pretty much naked?"

"Yes, so please, slap my ass as hard as you can."

"Get on your hands and knees and beg."

Shelby dropped to her hands and knees. "Please slap my ass as hard as you can. Please!"

"Follow us," said Bella, "crawl."

Shelby crawled after the Tri Delts into the locker room.

"We just had a nice sweaty workout," said Bella. "Tongue out our sweaty assholes, and we'll slap you ass. Get to it." Bella turned her back to Shelby and lowered her shorts and panties.

Shelby stared at Bella's naked anus. She was disgusted by the sight of it. She had never given a rim-job nor had she had anal. The thought of it repulsed her, but she could not help herself as she was doing what she was told. She leaned in and started licking Bella's sweaty anus.

Bella's sorority sisters took a video of Shelby's rim job. When she was finished, she tongued out the other two's buttholes while Bella filmed her.

"How's the taste of sweat and ass?" asked Bella.

Shelby screwd up her face and winced.

"Go rinse your mouth in the toilet," said Bella. "Keep crawling until you leave the gym."

Shelby crawled to the bathroom and went into one of the stalls. She flushed the toilet then rinsed her mouth with the toilet water. She then crawled back into the locker room. She saw that the Tri Delts were gone. "Oh no!" she gasped. She crawled back into the gym.
