I think my favorite fat scene is when the Shark breaks the pier. Honestly it does his over weight appearance from being turned into a pillowy shark justice. I want to see an event where he actually is stuck out at sea due to being too fat to swim and work it off. I mean, if you're having him gain weight from taking anal you might as well have there be some consequences for the character.
I also have a headcanon that the gladiator statue is a cursed warrior who can become an ally if you give him his sword back to free him from being a statue. A honey bee perhaps? Needless to say, this game has such a wacky and rich environment for storytelling.
I'm hoping eventually we get either equippable sex toys which affect spells and arousal during battle. Like a chastity cage which increases max arousal and allowing for stronger spells.
