I don't care if it's actual piercings or needle play I just need someone's something having metal shoved through it. I would love to see something like maybe a modern Queenie getting a corset piercing done. Or maybe Credence learns to love sharp pains instead of the more triggering things like impact play. (and c'mon Credence's back would be a glorious canvas) Or maybe Newt secretly got his nipples done ages ago in another country and someone is just fascinated and keeps playing with them.
Any - Piercing Play
