Modesty is perfectly dressed to stay all dry and clean regardless of what we throw at her, in her dark blue waterproof rain trousers and dark green waterproof rain jacket. She demonstrates the impermeability of her outfit, first by kneeling in a pool of spilled custard, and then by dipping an elbow into the same pool.

But of course staying clean and dry is no part of a Saturation Hall girl's plan, and so next she grabs a carton of custard and starts pouring it down inside here waterproof trousers, holding them open so we can have a good look inside as the custard splashes down and messes up both the trousers and the Spandex dance leotard she's wearing under her waterproofs.

A complete frenzy of gunge follows, she sits in a tray of custard to coat her bottom, and then stands up so we can watch her custard-covered trousers sliding up under her still-clean jacket, messing it up inside. She sits down again, then stands and fills the back of her trousers with more custard.

By the end of the session her entire waterproof outfit has been comprehensively coated, inside and out, in thick sweet yellow custard, and she's had a great time playing with it through the waterproof material too.
