Shrek looked out of his window and into the dark abyss of the swamp. He heard growling from deep within the forest. He wasn't scared, though, because he knew he could handle any threats.
"What was that?" asked Fiona.
"Can' ha' been anythin' we can' handle" he responded.
Shrek walked back to the toadstool bed where Fiona was sexily residing. Shrek proceeded to take off his vest, then his shirt, pants, and underwear. He was truly revealed to Fiona for the first time. They were about to bond in perfect harmony, united as one, when the door violently burst open.
It was Donkey. With Dragon.
"What! Are! Ye! Doing! In! Me! Swamp?!" stammered Shrek. But Donkey had his own agendas tonight.
"You cain't make ME leave tonight Shrek! I came here. For sexual purposes."
And with that, Donkey removed his pants, revealing his raging hard-on. Shrek was about to make a new, angrier proclamation, but was then after interrupted by Fiona: "Shrek, honey, why don't we let them stay? We have been wanting to spice it up a little…"
Shrek sighed, but allowed them to come in. Fiona motioned to Dragon inviting her over. She then winked at her husband, giving him the unspoken invitation to enter her clunge. As Shrek began to slam his meaty cock into her sweltered pussy, Fiona began to lick Dragon's clit. Only an ogre's tough tongue was able to withstand her scaly taint.
Shrek began to gyrate his hips when suddenly he felt a few hooves from behind. Donkey was preparing to enter. But this time, he had a surprise in store. Little did Shrek know, Donkey had gone to Fairy Godmother's factory to buy more of the viscous but smooth Happily Ever After potion.
As Donkey entered Shrek, Donkey became a beautiful stallion, and Shrek and Fiona changed to their most beautiful forms. All four began to feel elated.
Shrek just couldn't get enough of this. As Donkey entered and exited his sphincter, Shrek released a moan of pleasure.
Donkey then proceeded to hit Shrek's prostrat, causing him to ejaculate forcefully and hit Fiona's g-spot, initiating an orgasm. Fiona then pushed Dragon over the edge with her seductive tongue skills. The excitement of the situation released Donkey.
They all simultaneously orgasmed and the passion of the swamp increased, which caused the supervolcano beneath Shrek's swamp to explode, killing all of the extraordinarily happy characters instantly.
