Not against the rules! Crime to your hearts content, my friend.
Jokes on you, pal. I’m a nudist now so you wouldn’t be able to get me in the cage in the first place.
EDIT: I suppose you could just wear gloves... well luckily I’ve been working from home in a tiny back bedroom for over a year. Being in a cage would make no difference to me whatsoever. Plus, I get free windmilling penis entertainment.
