Very happy to see that the game is still being worked on!
Accidentally stunned my latex fetish progression in the beginning using a chastity cage: forgot that finishing is required to level it up and I locked it for 30 days TwT
Pretty sure you have to equip it, then go to "aroused", scroll all the way down, and there should be an action called "matters of chastity", where you can set how long you want to lock it for
