>You are Anon.
>Today is the day that you complete your masterpiece.
>Your whole life has led to this very moment.
>Ingredients were chosen with the greatest care.
>Varying temperatures and cooking times have been tested for months.
>Today is the day that you create the greatest chocolate cake in Equestria.
>It would have been a difficult task to spend all of your time practicing cooking, but luckily you have a job at Sugarcube Corner.
>Every day you got to create amazing delicacies and pastries for the town of Ponyville to enjoy.
>The ponies couldn't get enough of your cooking, and you were working on an entry for the National Dessert Competition in Canterlot.
>It's a simple cake, only three tiers, with fudge frosting in the middle.
>The bottom and top layers were a smooth milk chocolate cake while the middle layer was loaded with devilish dark chocolate.
>Preparing your heavy cream frosting that also has a strong dose of chocolate infused with it, a terrifying thought occurs to you.
>She hasn't disturbed your work today.
>Scanning the kitchen, you look for any sign of the pink menace.
>Nothing must disturb the master plan.
>Pouring your frosting into a plastic bag, you cut off an end and begin to spread the frosting.
>Slowly spreading the frosting over the cake, you take delicate care to insure that each knife stroke left an even pattern on the cake.
>After a solid thick coating, you turn around to throw away the excess frosting.
"Finally."
>Turning around, Ponka is directly in your face and giving you her signature bedroom eyes.
>Not this fetish shit.
>Not today.
"Get out of the fucking kitchen Pinkie. I'm doing something important."
>"So am I Nonny..."
>She walks slowly around the cake, inspecting it carefully.
>"This looks delicious Nonny..."
"Don't you fucking touch it."
>"I really like the love and dedication you put into spreading the frosting..."
>You stare bullets at her.
>She turns and stares at you with a burning lust in her eyes.
>"But you know what I like the most?"
>Grinding your teeth, you stare at the one person you can't do anything to.
>The cakes would fire you if you threw her out of a window again.
>You just had to take it.
>Raising her hoof, she takes some of the frosting and licks it off her hoof.
>"Cake farts."
>What?
"What?"
>"Hehe... you'll see."
>She slowly walks around the table one more time, as if stalking her prey.
>Getting up on the table, Pinkie presents her flank to you.
"Are you done yet? Don't fucking hurt my baby. I'll stab you."
>She giggles and slowly lowers her flank down to the cake.
"Don't you fucking dare."
>It comes dangerously close to the frosting.
>A single drip of sweat slowly runs down your face.
>Pinkie closes her eyes and holds her breath.
>"PPPPLLLLLLBBBTTTTTTTTTTTHHHH"
>Your jaw drops.
>Pinkie just farted on everything in this world that gave your life meaning.
>She plows her flank deep into the cake, and releases another long wet fart into your pride and joy.
>You feel your grip on reality slowly slipping into the void.
>Why would she do this?
>She slowly lifts her flank to you, presenting her chocolate frosting covered asshole and marehood.
>"You like this Nonny?"
>You see her asshole pucker, and drops another bomb directly at you.
>For the love of god, don't throw up.
>Your cake, no, the mass formerly known as a cake, is in shambles.
>Pinkies face turns red, and she gasps for air.
>With one final push, she begins to let out the loudest and wettest fart that you have ever heard.
>All you can do is stand and watch in pure shock.
>When she has completed the deed, she hops down off the table and rubs her hoof up and down your leg.
>"Are cake farts your fetish Nonny?"
>You stare at the demented mare.
>Finally, something inside of you snaps, and a smile crawls across your face.
>Well, looks like the lawyer is going to have to try and plead for temporary insanity.
>All because of,
>Fucking Cake Farts.
