I came up with the idea of an RGB gaming fleshlight/catheter for total immersion in games a decade ago as a joke, and I am basically 100% sure that such a thing, or something very close to that, now already exists.

I know there are… remote operated basically bj/handy machines, I just dont know if they are RGB and also allow you to piss, cartman style, so you never have to leave your gamer throne.
