Cassy pulled down her pants and panties, exposing her ass and pussy to everyone, later she used the gel and applied it in her ass. "Oh Cassy" Maddie giggled silently enjoying what was going to happen, "this is going to be so fun" said Gina covering her mouth while trying to not laugh. "Look closely at her face because it'll be the last time we're going to see it," Cassy laughed, so that seconds later she sat on Cassandra's face. For a few seconds Cassy thought that nothing happened but then she felt her but sticky attached to Cassandra. Their bodies acted like a bubblegum, Cassandra's body quickly was fused and absorbed by Cassy's ass, the change was so fast that the girls didn't notice while Cassy's ass was notably bigger. "What? She disappeared almost instantly," Gina expressed, "it means it worked?" Maddie asked, "Let's see" Cassy said as she bent showing her ass to her friends.
When the girls decided to check Cassy's butt they noticed that were two closed eyes up her anus, Maddie and Gina couldn't contain and gave a huge laugh. "HAHAHAHAHA it worked! Cassandra is now your ass!" Maddie and Gina kept laughing, "Hahaha, let's wake her up", after Cassy said that she farted making Cassandra woke up. Cassandra was confused about what was happening around her, she felt two big things that were squeezing his face, her mouth was constantly in a "O" shape without being able to move it, she had no nose and couldn't feel the rest of her body more than her face. "How are you Cassandra, felt comfy?" Cassy asked in a sarcastic tone, then Maddie brought her face close to Cassy's ass. Maddie was giant from her point of view and couldn't understand what was happening, "You still don't realize? You're no longer Cassandra, now you're Cassy's ass," Gina said, "Yeah, and it will be the rest of your life, you were an asshole but now you're one literally hahahaha" Maddie grinned, "Yes, so get used to the smell and taste of my farts, shit and sweaty ass" Cassy farted again and giggled with her friends. Cassandra would be crying of pain if she could, but now she needed to accept the fate of being the rear of one of the girls she annoyed and taste the disgusting things she expelled.
"What could we do now, there's a lot of possibilities with this gel and Cassandra… I meant, Cassy's ass, what should we do now?" Maddie asked.
