Hey. Looking for a story where the a girl at a party wanders off upstairs into a room and finds a space in the floor for someone and it's hooked to to the toilet; they find it hot and close the doors on the contraption thinking they can get out except they can't. Then someone turns up and thinks it's his girlfriend finally being kinky and decides to use the toilet.
Got a sketchy memory of it but wondered if anyone had an idea what this could be?
Thanks
