May ik the locations of the toys you currently have found. I just got the first Buttplug.😅
The others are the tail buttplugs which can be bought in the second town shop, and the egg vibe is given by an npc after clearing the first dungeon and doing the exhibitionist activity.
Although, I've heard a few times there are also dildoes in the game, but I've been searching extensively for a few days and havn't found any so, idk.
