Under the intense heat, on a deserted road, passed the green automobile that is the infamous Mystery machine. It clocked at a tremendous speed of 69 miles per hour. Inside the rusty old vehicle were the sleuths: Fred, Velma, Daphne, Shaggy and their dog mascot, Scooby Doo.

Scooby wasn't his usual self lately. The mutt was pale and shivering at the back of the van. The poor dog has been feeling under the weather days after the gang kicked off their road trip to Mexico in hopes of capturing the treacherous illegal logging duo, Dora and Diego.

Scooby's owner and bestfriend, Shaggy knew all too well what the hapless canine is going through. That's because he'd experienced it himself years ago. The feeling of sexual frustration. The man tried to mercy jerk Scooby but the dog slapped it away for it only wants pussy to cause his long awaited ejaculation.

You see, Shaggy, being the good owner that he is, casually tracked his dog's heat cycles to aid it in finding a mate beforehand. One time, Shaggy used Scooby's nephew, Scrappy doo, as a sacrificial lamb since he failed to find salty dog pussy for Scooby to fuck raw. He also recalled the time he bribed Steve from Blue's clues to let his dog, Blue, be fucked by Scooby right in the asshole. Now, stuck in a van, he can't do anything but watch his beloved companion suffer from blue balls. The thought of that made him chuckle before turning his attention and body towards the driver up front.

"Like Fred! Could you slow down a bit?" Ordered the concerned Shaggy. "Scoob's like sick, man"

Fred who was drinking a can of beer, instantly pivoted his head to face his complaining passenger.

"Fuck Off" he replied in his soft voice then set his eyes back on the road thereafter.

"Time is of the essence, Shag... we're talking about illegal loggers here! Let's not lollygag OK!"

Shaggy's brows drooped after he heard his friend's response.

"Like, can you at least stop when you see a stray do.."

"To hell Shaggy! Fred snapped. "We ain't stopping until I get my hands on Chiquitita Dora"

Those last two words made Fred's cock twitch and throb; it bulged enough to have it's form marked on his blue pants.

The female passengers saw it and giggled hysterically.

"What the hell are you laughing at!?" inquired Fred before grabbing Daphne's hand and places it on his crotch.

"Why don't you shut up and do something useful..." he continued with lust in his tone.

Velma, feeling left out, could only stare out of jealousy while fingering her nerdy vagina as Daphne fondled Fred's lumpy groin.

Amidst the ruckus that developed at the front, Scooby lay massaging his thrumming penis; His scrotum shriveled like a medieval coin purse and his asshole clenching shut. The lack of intercourse made him flex his entire body causing his blood vessels to swell. He longed for the sweet pleasure of having his red rocket buried deep inside another organism. At this point, he doesn't care anymore if it's a dog or any other animal. The horny hound only had one thing in mind; to feel the sensation of moist flesh wrapped around his painfully stiff cock once more.

As he masturbated, Scooby noticed Shaggy's lusciously ripe ass behind the very tight pants the man wore.

Shaggy was too busy to suspect the contours of his asscheeks being visible as it got pressed by his jeans after bending over to prevent his head from hitting the ceiling.

Scooby's eyes sunk back into it's sockets all the while turning bloodshot as he saw the seemingly inviting ass of his owner. It wobbled which, to Scooby's understanding, taunting his sexless ordeal and asking to be ravaged silly.

"R'oh Shit!" exclaimed the aroused dog; his cock expanding to uncharted lengths.

He couldn't hold it any longer. He needs a mate; nature requires him to. Scooby galloped towards the tempting male ass, ready to uncover it from it's fabric bindings.

The dog took a deep snort of Shaggy's buttocks before pulling his owner's pants down to his ankles.

"Like, What in tarnation!" The man reacted.

Scooby was amazed at the butt he just unveiled. It was smooth and powdered like a newborn. Perfection like that doesn't come around often.

He splits the ass sideways and gives it a lick starting from Shaggy's wrinkly balls up to the peak of his ass crack; making the surprised man jiggle his glutes.

"ZOINKS!" Shaggy yelled but was soon muffled by the dog's dirty paws.

"Forgive me Raggy, for I must fuck..." Whispered Scooby in his retarded accent. "I rike you and I want you..."

The hound knew Shaggy was a virgin so the application of lube was a necessity. He positions his snout at the man's anus then CHA-CHING! Sticks his long tongue out like an opening cash register; injecting Shaggy's bum hole with it.

Shaggy cringed as Scooby did spring cleaning inside his rectum with it's organ of taste.

Fred and the others, knowing Shaggy and Scooby always does weird shit at the back, ignored the chaos that ensued. In addition, the lack of windows were enough to give the space shade for Scooby to hide his salacious endeavors.

Afterwards, Scooby removed his tongue out of the asshole and watched Shaggy's drenched ass shine.

"Like, enough of this nonsense dog!" Demanded Shaggy.

Scooby towered over the man and responded "Nay... You have failed offering me a mate"

His eyes glowed from the sunlight "And that is a crime for which you must give to me your own anatomy"

Shaggy was aware that his dog was beyond saving, so he took out a pack of edibles under his shirt. "Would you fuck me gently for a scooby snack?"

"No thanks... I have my own pack right here" Scooby said as he palmed both of Shaggy's asscheeks.

It is indeed true; Shaggy's behind sure was a snack; perhaps even more flavorful compared to the actual junk food; the sweet anus hairs gave it additional zest and texture.

Afterwards, Scooby readied for his act and prepared his monstrous cock for ignition. Shaggy was frozen out of fear; His pet's penis was scarier than all of the spooky ghouls they've encountered in the past.

Then, the perverted dog rammed his cock between the mountainous manbuns.

"ZOINKS! ZOINKS! ZOINKS!" yelped Shaggy, each word corresponding to Scooby's thunderous thrusts.

"RIHEHEHEHE!" Scooby laughed for he had finally performed sex.

Slapping sounds can be heard as Scooby's nutsack smacked against Shaggy's balls gracefully like a pendulum; maintaining a steady swing with each scrotum taking turns at being the collider.

Meanwhile, Velma who was annoyed at Fred and Daphne's moaning, decided to transfer at the back to hang around with the weirdos. As soon as she turned, Shaggy is seen being manhandled by his own pet. That of course made Velma dripping wet.

"Got room for one more?..." She seductively asked.

Scooby, who was caught by surprise, pulled out then fell on his ass. The dog didn't expect that they were gonna get caught. He'd already planned this out before he commenced his assault; Guess it failed.

"Do not fret, you sexy dog" Velma assured, she was stripping. Her breast were now exposed. "I wont tell"

Scooby's jaws dropped at the sight before him. Velma's jugs were king-sized... No, Queen-sized! And God save him for he was about to lose consciousness.

The dog smirked creepily and signaled Velma to come and offer herself to him using his cock. It twitched three times. Velma got the idea and crawled sexily towards the shadowed dog at the corner - who is now groping his aching nuts.
