"Was that deliberate, or did you really just trip and fall?" Anna asked.

Emily raised her head from the cake frosting that she had just body planted into. Her black hair now streaked with white.

"I really wish I could say that was deliberate..."

The black dress she was wearing had not offered much protection, the icing now covered her head, arms, stocking clad legs and had made serious in roads between her cleavage.

"Want to offer me a hand?" She asked Anna.

"Well, I was thinking as you're already in the start line, we could do with a stooge for demonstration purposes."

Emily's hands were pulled behind her and strapped together. She felt straps on her ankles. Cords pulled them up to her wrists, hogtying her. Anna stood above her.

"As you know, 30m of cake lies before you. You must wriggle your way to the other end before the three mechanisms catch up with you.

The first mechanism will strip you.

The second mechanism will spank you.

The third mechanism will drag you all the way back down to start where the Beast eagerly awaits, ready to ravish you.

"And go"

Emily began wriggling her way up the cake. She felt the frosting ooze into her dress. Ahead of her was a large pile of icing. She sighed and plunged her way through. Her head was covered in a thick layer of white.

She had just worked her way through the pile when she heard a siren, and she realised the first mechanism had caught up.

There was a tug on the back of her dress. With the sound of a scissor cutting, her dress was removed from her.

"Emily! You weren't wearing any underwear?"

Emily could hear the grin on Anna's face.

She was now dressed only in stockings and cake frosting.

Emily continued to squirm forward, feeling the frosting on her breasts, stomach and now between her legs. Her clit throbbed as she felt the ooze on it. There was a splat, and she felt an impact on her backside.

"That should help you cover up."

Anna had pied her arse. And she didn't stop. More pies hit her back as she writhed.

Emily shivered in excitement as she wriggled forward, her breasts sinking into the frosting and soft cake each time she moved.

Thick foam started to spray over her. Warmth spread through her and Emily recognised the aphrodisiac effects of the foam.

A second siren sounded and she felt something grab her hips; the second mechanism had arrived. With a twack she felt a paddle hit her left butt cheek. Then a twack against the right cheek. She moaned, groaned and gasped as the sensations resounded through her. 20 whacks, 10 to each cheek she counted before being released to continue her jiggling forwards.

A curtain of gunge poured down over her head. It kept streaming down as she crawled through it, coating her body. Slightly soothing her red spanked arse.

Emily lifted her head and could see the finish line a few meters away. Although with all the goo covering her, it was a slippery and slimy crawl.

She felt two hands on her thighs, and she shrieked as she felt a tongue lick along her pussy. Emily finally orgasmed as Anna gently nibbled the tied woman's clit, squirting over her tormentor's face.

"I delayed the third mechanism.

Anna kept licking Emily's pussy, making her squirm and gasp and cum over and over again.

"I so love making you lose all rational thought." Anna grinned

Emily lay, only a meter from the finish line, but gasping and shuddering from the pleasure. A cream covered Anna wriggled around to her head.

"I want to see your expression."

Emily was momentarily confused, before remembering the third mechanism. There was a pull on her restraints before it increased and she was slowly dragged back through the cake towards the start, where the Beast awaited. Through all the frosting, cream and gunge she had crawled through. All of which was funnelled up between her legs, pressed against her pussy and over her body.

The Beast would have to dig through a mound of messy goodness before plowing her into a limp puddle. She definitely hadn't finished cumming for the evening. And when she felt his rock hard dick enter her dripping pussy all Emily could think was how much she loved her job.
