Two Things:
First, I think the Wyld Elf Troupe in the Old Forest should drop Wyld Wine. It’d make sense, especially if you choose to party.
Second, I’d really like non-piercing versions of the Ghostlight Strapon and Heat/Rut Piercings offered by Lady Evergreen. That Mallachite Paladin has a Ghostlight attached to his chastity cage, so we know it doesn’t necessarily need to be a piercing: maybe it could be tied to a specific set of underclothes, like the Hardlight panties of TiTs.
Meanwhile, in the scene where you get the Heat/Rut piercing from Evergreen, she does suggest a crotch tattoo as another option. Sure, it couldn’t be toggled, but I think that’s still a valid tradeoff.
