Ok, if you're that kinky sort of person, this is for you.
There are plenty of kinks out in the world, such as costumes, role play, wax etc.
And I don't know much more, but you might.
Maybe you can search these up? ( and please for the love of God use a private/incognito tab and then clear all history afterwards, you wouldn't want someone snooping around your Internet browser history and come across some site that you probably shouldn't be o but anyway)
Maybe your characters could try a little bit of 69? 😏
