Professor Samuel Oak was working in a rigorous field study in Viridian Forest. The majority of folks thought he'd quit field work and switched to lab research, and they weren't mistaken because the elder had indeed retired. The reason he came out of retirement was because his hot milf neighbor's son, Ash Ketchum, whom he had offered child labor to, still hadn't returned with a completed pokedex yet, and it had been three decades already. Bastard probably have hairs on his ballsack by now. He wondered what's taking Ash so long, even an old guy like Oak himself cleared the Kanto region in just one sitting of Pokémon Yellow on Gameboy.
After spending the entire morning trying to lure Machops, Ralts and kids in Machop and Ralts costumes into his white research van, he elected to stop for a moment against a large tree, checking out a passing wild Jinx's badonkadonk.
"Wop-bop-a-loo-bop! Damn hoe!" Oak learned harden by leveling up his penis, "That Jinx be havin' effects on me prick!"
Samuel hadn't felt this point of arousal in a long time. His last erection recollection was of when he had a front seat view of Ash's mom and her Mr. Mime having some kinky interspecies bonding from the window.
As one might expect, the poke-expert had to get one off. He took out pokeballs from his sack. Then, painfully, one by one, he shoved em right up his asshole. This isn't his first time; he did a similar act when he inserted the three pokeballs he usually hands out to novice trainers right before making them choose one. The pleasure invading his anal was powerful, it made him convulse and ejaculate old guy moans, spitting out his dentures into a pile of Pidgey crap by accident.
"Shit! Curse my hormonal impulses!" curses the professor, standing up to retrieve his belonging; only to notice that he had made a deep puddle pool of his cum, and various water-type Pokémon have already taken residency in it. For him, it served as the ideal case study for Pokémon habitats. He might win the Nobel Prize for discovering semen-type Pokémons.
Oak gathered to start his investigation when a sudden explosion from the clouds arose in biblical proportions.
"Forgive me Arceus! I have not known that I have sinned!" Prayed the scientist, thinking jacking off to Jinx butts was a sin, which obviously is not.
The elderly looked up and spotted a burning object heading south from the sky. It took some time until it landed a short distance from where he stood. Once he figured he was not smote by the lord, Oak calmed from his anxiety attack. Wearing back his dentures, he goes to the crash site to discover what the object was.
The site was still smoky minutes after the initial landing. Professor Oak made a steady progress toward the object. Based from what he saw, Oak can make out a vehicle of some sorts; a ship. When he cracked up the dented hatch, a strange, bony, turd-looking creature sprung out. The short critter ran pathetically, like it had its pants down to its ankles, before losing its balance and crashing to the ground, farting violently.
"Lol what a loser" Laughs Professor Oak. He went closer to the collapsed being to examine it more. He wrote its details in his logbook: Sexy... yep that's about it. It was a monster Oak happened to find interesting... or better yet, attractive? What could it be he would ponder. A new species? or it might be an already existing Pokémon.
"Perhaps it's a Croagunk" Oak taps his pencil onto his lips, "A Croagunk... but... retarded"
Suddenly, the monster woke up and groaned, as if it was offended. "E.T"
Oak backed up, startled that it had just spoken. Pokémons are usually given names based on the sounds they make, for example, Pikachu. So, Oak adopted the norm and call the alien as E.T. Given that it was immobile, Oak took the initiative to test it by collecting samples of its snot, armpit hair, and other bodily fluids. After the basic operation is complete, it's time for his favorite procedure: Pokémon gender and sexuality testing.
The Pokémon professor professionally ripped E.T's almost non-existent legs apart, discovering its long beef Erikson the length of a broadsword... and shield. The penis looked nothing like the penises Oak had research from Pokémon of different kinds. Oak smacked his lips at the sight of the jerky dry protein. Looks like it's a male. Most true men such would normally be repelled by the penile showing, but not Oak though. It only attracts him even more. He kept his composure, flipping the alien over, face down ass out, and had a close encounter of the turd hind; E.T's yellow UFO-shaped mouth breathing asshole. Oak took a good whiff at it, first-class aroma of truck stop restrooms mixed with summer-cooked crusty cow crap nuzzled his nasal cavity and made the old man upgrade his old rod to super rod. His penis finally replaced Minimize with Growth after keeping the move for so many years.
With E.T's sex now determined, Oak was left with one thing to do. The most important of all, Human compatibility test.
"Time for your final analysis, E.T" remarked the Pokémon doctor, ferally ripping his pants to bits, which gave freedom to his oaky woodhammer. Its size gave the professor's name justice.
"E.T... hungry" informed the alien of its current state.
"Don't worry... E.T will Eat my D" responded Oak right before he hid his cock up well inside E.T's intergalactic stink attic.
"EhHhheKh!" E.T's neck extends in surprise as it yells that duck sounding scream he did from the movie. It got a few inches added to its petite stature. "E.T... Hungry...for love!"
The professor had rough skin. So with each thrust of his, E.T takes extra damage to his HP... or it's because Oak didn't used any lube why E.T got scraped.
Samuel Oak gasped from the sticky hold of the extraterrestrial anus, basically E.T got his poor oak choked. He felt the complex structure of the alien's innards. Protruding cartilages were everywhere around E.T's walls like one of them bumps on acupuncture slippers, and they're moving too like a grinder, macerating the professor's flesh as it passes by. A bead of pre pops out his slit after the ass tightened in response. Oak was fascinated and pushed his trunk all the way down to the roots to learn more about its anatomy.
"Let's hop down jagged pass real quick"
He presses his luck and hopes he won't get a smelly whammy. But luck wasn't at his side as he felt a warm nugget someplace in the deeper layers.
"What the Fuck" Professor pulled out and E.T shook with anticipation. Then Oak did an arm thrust into the dotted hole in order to retrieve the obstruction, tugging out a large rank dookie.
"P.U! Spoiled lava cookie"
Oak puts that chunk inside his bag. He's going to sell that nugget at the Pokemart for 5000 dollars, then spend that money afterwards for a truck load of PP Ups aka Viagra. After that, he returned his cock into E.T's cheek pouch with pure power, making the extraterrestrial countered with a shriek of otherworldly lust, its frog hands claw the soil and it moans with each pound. It was a song so erotic, so beautiful like it's being played with a Pokeflute.
Oak's excitement was building a speed boost until he's forcibly pulling on the flanks of E.T buttocks for leverage, stretching its rubbery skin like a reign. His thighs slapping painfully against E.T's boney ass.
"I am a man of knowledge!" whimpered Oak, looking for some form of justification from this vile act, guilty that he's actually enjoying this. "I'm doing it for science! FOR SCIENCE! Don't call me a degenerate, GOD!"
Oak knows how to play rough. What started out as a slow start quickly shifted into fast one as the breeder was now driving with extreme speed. He rests his head over E.T's disgusting wart-like head.
"Sing your Elvis! sing your Elvis!" Oak moaned into the alien's ears.
E.T whistled "Hound Dog" and that brought the poke-expert to the edge. Oak feel E.T's insides contract around his hip leech. E.T lets out a long whine as his walls tighten shut and begin trembling.
"Oh Arceus, My Oran Berries are ripe!" Oak can't hold it any longer and grasps E.T's hipbone to bulldoze himself deeper into the extraterrestrial homosexual.
"Hippity Hoppity! Here comes the slush rush!" Oak milks his Miltank and makes one final blow. His orgasm erupts in a violent throb. He basically used up all of his PP with that single, powerful gunk shot, which dropped a massive seed bomb into E.T that was too much for its asshole to take and stockpile. Quickly, Oak transferred to E.T's mouth and drained the leftover muck there inside it. He's a firm believer of preserving every drop of his hard-earned jubilation.
Oak saw E.T choking from the cum, spitting up the liquid. Oak finds it immoral to reject a man's gift. He swiftly grabs a disk from his bag.
"Swallow! Swallow damn you!" Samuel desperately slapping the Swallow TM against E.T's caving forehead; just so it can learn the move. "The food ain't that bad, Baby!"
Trained, E.T trusts his trainer and fruitily croons as he welcomes every drop of oak sap with an intense suckle, not a single sign of regret came from those throaty gulps.
The tension of the moment fades. The two of them are now left in an embrace, sweaty. E.T sags down onto Oak's chest. It twirls its claw against the professor's skin as he catch his breath.
"You're pretty good, E.T" complimented Oak, lying beneath E.T and cock mushed by its oily belly fat.
"E.T... Pretty?" the alien blushes.
"Lol, you wish" responded Samuel Oak. "No, Don't get your hopes up, you ugly motherfucker"
