A little what if. Maybe just a dream.
If you imagine by some unbelievable completely unexplained shenanigans of fate Calla will return from Mareth. And when she does, she'll be completely fucked up. Transformed into infernal succubi-kitty, equipped with man slaying demon pussy and eleven inches long barbed bitchbreaker between her legs. After bragging how foolish she was to reject the path of a temple whore and how now intent on making up for all pleasure of world, the battle begins.
Which our guys are lose, miserable.
Next Calla put a spell or maybe use some magic artefact on Cait, making her feel everything what's Chump feels. Then she uses all the assets she and you have, in every possible way, to completely break her sister's will be giving her the true mind break without fucking her directly.(ha-ha you have no power here, Patreon the Prude).
It's super effective!
Completely corrupted Cait join Calla and together they're gonna fuck Champ soul out.
Your future fate is to be the plaything of two sister cats, until the end of time.
The Bad (happy) end.
