I cannot wait to see what else you add after the latest curse of boyfriend update. I want there to be a sex toy store for cursed sex toys which all have unique properties. For example one that is a cursed chastity cage that increases max mana and arousal rate, but will give you higher stacks of pent up. Unless you have an anal orgasm.
Another idea could be a cursed dildo which gets stuck in your butt generating arousal faster and lowering your max mana, but it makes you gain muscle faster. That sort of thing.
These are just a few ideas. I also kinda want the vendor to be the fox cultist. Just for there to be a way to learn more about him.
