Squidward was sitting at the cash register on his daily work routine. all was normal and boring, which was fun for him.
Everyone in the restaurant assumed he was just sitting there alone, waiting for the next customer
But in reality, he was looking down into the boat where no one could see, looking at pictures of his long lost love, Shrek.
Shrek and squidward had been in a very physical relationship for 5 years a long time ago, but things didn't work out and shrek had to "Get me a new swamp."
Squidward had had erotic thoughts of Shrek since the day they separated, in a balance of bliss and longing.
So, back to squidward's activities, He was looking at a particularly racy photo of shrek.
It was very revealing, he was holding onions to his nipples and doing an irish jig.
His enormous 12 foot snake was dangling and swinging below him.
squidward moaned from the thought of shrek's titanic throbbing rooster penetrating his squid ass.
Squidward regained his senses and looked up from his dream to see a familiar sight.
A rather wide individual strolled in the Krusty Krab doors, wearing a large cloak with a cowl over his head.
Squidward craned his neck to see under the hood, and gasped with delight when Shrek's face came into view.
Squidward jumped out from behind the register, hugging shrek with his tentacles.
He heard a familiar voice in his ear, one he would always remember.
"I've come back to me swamp, squiddly."
Squidward was hard beyond belief, rubbing his squid appendage against shrek's smooth green skin.
Shrek's eyes widened, knowing it was time.
Shrek began charging everyone in the room, throwing them out of the windows and through the doors. "My leg!"
Squidward came up close to shrek and ripped his cloak off to reveal shrek's beautiful round body.
Shrek belched loudly, and said "You can stay in me swamp as long as you like."
Squidward then proceeded to bend over for shrek.
Shrek had to take 12 steps backward, and unleashed his full 12 foot long girth.
Shrek began penetrating squidward with the force of a jackhammer.
Squidward yelled in pain, but in ecstasy at the same time.
Shrek unleashed his green, onion-smelling load into squidward's ass.
Squidward passed out from climax, and shrek returned to his swamp for a dinner of onions with his Donkey.
the end.
