Someone had to look it up, and today that someone is me.
Cake sitting?
For my first hit seaching "cake sitting fetish" there's Mistress Ursula, a pretty strait forward S&M style dominatrix,
who lists cake sitting as one of many varied interests. If you ask me she's just in this to make a few bucks.
Then there's a Betty Page-esque woman named
Ducky, who is all over the net. She's apparently a former performance "peep show girl" who dresses as a sexy (?) clown she calls Knockers, shown in
this article sitting directly on a cake.
From the article:
There’s usually a barker there saying ‘Knockers really likes cake. She REALLY likes cake. Don’t you sit on that cake Knockers!’
Also from the article:
Knockers’ whole approach to clowning seems to be geared to pissing off the Birthday Clown Union, a legitimate membership organization that has very rigid rules about what clowns are permitted and not permitted to do while in clownface.
Ducky, seems to actually love what she's doing and seems be more Ray's type, if it's possible to have a type when you're a cartoon cat who is aroused by cake sitters. So there's this whole world of Klown Sex, and at least for Knockers this seems to centre around the destruction of cakes... who'd of thunk it.
