Was reading a co-worker's newspaper upside-down as we ate lunch opposite each other and was pleasantly surprised to see a full-page spread about a man (presumably someone on here?) paying women £150 to get messy. Didn't get a proper read of the article but there were several pictures. Hopefully someone can fish a copy out of a bin and confirm what I saw?

I did not find anything for yesterday's Sun but I did a splosh search and came up with these. The first is a 2016 article that sounds like the one you were talking about. https://www.thesun.co.uk/living/1921902/meet-the-glasgow-dominatrix-who-charges-150-to-cover-sploshing-clients-in-custard-in-an-sm-dungeon-her-dad-helped-build/

This July 2017 piece had a reference to sploshing with a short clip of women sitting gently into desserts and jello molds. Caution: there is one hairy male butt. https://www.thesun.co.uk/fabulous/4121195/the-a-z-of-weird-sex-from-aghalmatophilia-attraction-to-statues-to-zooerastia-watching-animals-mate/
