Tier 3: Multiverse of Horniness (Patreon)

While exploring a decrepit government facility in the ruins of Seattle Abby and Mel accidentally activate and inter dimensional portal. 

 Mel is sucked in and finds herself popping into existence in the bedroom of a strange looking girl called Chloe with blue hair and an oddly familiar voice - her own. Shortly thereafter another two strangers, Beta and Tiny Tina, pop into existence and they begin to realize they’re different versions of each other.   

They also discover that one of the side effects of inter dimensional travel is a burning desire to fuck your alternative self.   

Meanwhile, back at the portal, Abby is making a very similar discovery with Polina and Nadine.
