Illustrious knows all about bondage, bless it. But it does seem to struggle with the idea of someone tied/cuffed to a radiator. So this is an attempt to address that.
Description
Version one - needs testing - not as strong as i'd like it to be. But adding "tied to radiator" helps, seems to recognise this tag better than vanilla illustrious,so it's doing something...
"Handcuffed to radiator" works too.
