Katie Cooper is hard at work operating the computerised gunge factory at HotWamHQ.  She connects valve A to pump number 3 and suddenly alarms and sirens sound . . . she has mixed up the smooth new colourful gunge with the chunky mixed up sloppy leftovers!  Horrified, she turns to the camera and asks `am I in trouble?`<br><br>Kate finds herself chained up on the factory floor, and squeals in disgust as mess is flung at her.  Her satin dress offers little protection against an onslaught of gunge and muck that coats her office outfit.  She looks up in alarm and says `What`s that pipe up there?` just as a torrent of gunk hits her square in the face.  Her bindings mean that she can`t wipe the mess off, and wriggling to try and release herself just flashes her skimpy underwear.  She writhes around in the mess as multiple layers of muck rain down on her.  `Could this be any more humiliating?` she asks, before her dress is pulled down!  It reveals a seethru bra that doesn`t stay up for long as torrents of gunge and slop rain down on her from above.  <br><br>After a torrential pasting of mess, her dress is removed completely and Katie sits helpless in a tiny thong, her wrists and ankles still bound.  She gasps and squeals as vibrant orange gunge floods over her, but is she starting to enjoy this?!  `I don`t understand why I`m being punished, this mixed up gunge feels so good to play in!`  She begs to be released so that she can show us how fun it is to play in, and after wriggling around she goes onto all fours, looks over her shoulder at us and says `go on then, mess me up`.  Her peachy butt is coated with a flood of purple and green gunge that clings to her incredible curves and covers her tiny thong.<br><br>Next, Katie decides to scoop up a big jug of mess from the floor and fill her knickers with it, giggling and gasping with a wicked grin on her face as the thick gunk gets everywhere.  Enjoying her self-messing, she fills jugs and bowls from the mixture on the floor and pours them over her face.  The last bowl is placed behind her and she lays back into it, dunking her hair over and over until it`s a sodden lump.  Katie grabs another couple of full jugs and while she lays on her back she pours them straight onto her face from above.  She arches her back and rubs mess across her hard nipples as the total coverage begins to overwhelm her self control.<br><br>A rain of chunky porridge is next, before she`s back onto all fours for some science!  `I need to compare the original gunge with the mixed up slop` she says.  Don`t worry Katie, we have the technology! The split screen view shows a closeup of the gunge hitting Katie`s naked derriere and flowing down her pussy, while the wide view shows her simultaneously plunging her head deep into a bucket of chunky slop.  After getting double-teamed by the different textures, Katie pulls her head out of the muck and announces the results of her testing.  `I need everything, everywhere, all at once!`<br><br>Now laying on her back, Katie abandons herself to the mess.  No longer a professional office worker, she writhes and moans in the pool of slop, begging for more mess.  One hand scoops the slop across her face and body, while her other hand desperately fingers herself, and wave after wave of every kind of mess deluges her.  Finally after multiple buckets of gunk are dumped onto her face she cums, bucking and writhing as the mess drives her wild.  Reluctant to finish Katie wallows in the collected goo, plunging her head over and over into the deep pool of mess on the floor, before finally we fade to black and enjoy some out-takes and bonus footage.<br><br>
