Freebies Vol. 54: Chemicality Edition!

Chemicals, the wonderful plot points of many a TF scene, are a great way to turn some unsuspecting (or suspecting!) character into all sorts of naughty, hilariously hypersexed beings.

Round 3: Shakal

"...and just one more initial here. Okay! We're finished with the paperwork."

Shakal leaned back in his high-backed leather executive chair. Across the broad oak desk sat Vincent, an attractive cheetah with the typical yellow and black markings of a cheetah. He was young looking, but in great shape. While chatting earlier, Shakal learned Vincent was heavily involved in track and field as a long-distance runner, which lent itself to his lean, powerful legs and skinny upper body. Cheetahs didn't normally go for long distance, preferring sprints instead, but Vincent expressed his love of cross country several times.

Shakal, a broad-shouldered black panther, smiled as he listened to the cheetah talk. His purple eyes sparkled as he eyed the lithe male, already imagining all the dirty things he'd soon be coercing Vincent into doing. Normally they would do the injection for the study in a lab, but Shakal had other plans for this attractive male.

"Now, the last thing," the sleek panther said, standing and brushing down the fur on the back of his neck. "You'll receive one injection a week for two months, but you'll remain on the campus here for three in total so that we can monitor its effects. Any questions?"

Vincent shook his head. "Nope, seems straightforward."

"Great. You'll be paid at the end of the study for your time and... I forget, have you been shown around the facility?"

"Yeah, I know where the cafeteria is and my room."

"Great. Stand up over here, please."

The panther smiled beguilingly as he rolled up Vincent's shirt sleeve. He sprayed a small area of the cheetah's upper arm with a disinfectant spray before opening a small black case on his desk. A gleaming syringe and a small bottle of clear fluid rested inside. After filling the syringe, he held the tip near the cheetah's shoulder.

"You may feel a little prick..."

A moment later and the deed was done. Vincent rubbed his arm after Shakal withdrew the needle and nodded his head. The panther grinned and leaned back against his desk. He couldn't stop his tail tip from twitching rapidly, but he kept it behind the desk, out of the cheetah's view.

"How do you feel?"

"I dunno... okay, I guess. I mean... well... oh..."

Shakal lowered his eyes, glancing at the slim feline's hips. A mighty boner pushed out against his tight jeans. Vincent looked down as well and, realizing what Shakal was seeing, turned away.

"Oh! Sorry, I don't know... what's... come over me... I feel so... so..."

The cheetah's words trailed off and he turned back towards Shakal. He was breathing hard and panting. The panther's fiendish grin spread. The drug was working faster than he'd anticipated. All Vincent was told was that they were testing a libido-controlling drug on him. What he hadn't been told was that the drug would make him unable to function without regular sex.

As the cheetah moved closer, paws trembling, Shakal thought about modern science and what a wonderful thing it was.

"How do you feel now?" Shakal asked, keeping his arms to his sides for the moment.

"I feel... hot... like I need something," Vincent gasped. His trembling paws lifted, going to Shakal's suit coat, gripping the lapels. "What... what's happening?"

"Perfectly normal, just perfect," Shakal said soothingly, carefully disengaging the cheetah's claws from his jacket. He took it off and hung it on a coat rack near the door before turning the lock. Turning back towards Vincent, he saw the panther's eyes were already glazing over and one paw rubbed furiously along his erection inside his jeans.

"Would you feel better with those off?" Shakal suggested. The black panther slunk back across the room, thick legs carrying him easily, until he was mere inches from the cheetah.

"Ye... yeah..."

"Here, let me help," Shakal said, a deep purr underlying his voice.

A few minutes later, Vincent was trembling, naked, hard as could be. Shakal licked his lips, seeing how firm the cheetah's erection was, and dragged a single claw up his belly, through his white chest fur, over his neck, and tipped the smaller male's chin up.

"Do you want me?" the panther asked, purple eyes blazing.

The cheetah groaned and nodded, unable to stop the words forming on his lips.

"Yeessss..."

"Just perfect," Shakal repeated.

His shirt and tied flew off, followed by his pants. He grasped his sheath, already thickening, and a moment later his long pink shaft dropped free, rising rapidly into the air. Vincent stared, eyes wide, as the meaty appendage poked his skinny belly to the side of his own pulsing, shiny black shaft.

"Why don't you turn around?" Shakal suggested.

The cheetah did, lifting his tail like any good submissive would, and Shakal spit into his paw, working the saliva over his cock as he stared hungrily at the lithe feline's ass. Vincent's palms spread over the smooth wood of the desk as Shakal stepped in close behind him, using a paw to rub his cock along the fuzzy white ass cheeks.

"You want it bad, don't you?" he whispered.

"Unnghhh... yes... please!" Vincent moaned, pitching higher as his desperation grew.

"Good boy."

Shakal grunted as he fitted his tip to the cheetah's tight tail hole. He was excited for this - the feline was so damn hot. The black panther pushed forward slowly and twisted his ears forward when Vincent let out a deliciously dirty moan of approval.

He pushed in sharply, grunting when he felt the cheetah's tight walls clench around his slick length. Vincent's legs trembled and he nearly fell onto the desk as Shakal pushed in deeper, taking him one long, deep thrust. He leaned into the cheetah's backside, muzzle resting over the smaller male's shoulder. He could feel the cat's heart beating like a drum and he spread his hands out, covering Vincent's, holding them onto the table.

"Oh, yes, you are so tight!" Shakal growled, drawing his hips back for another deep thrust. Vincent mewled helplessly, hips grinding back onto the fat feline erection spearing under his tail.

"Ha... harder!"

Shakal closed his eyes, purring with delight as the submissive bottom pushed back against him. He lifted his paws, stroking up Vincent's flat, hard stomach and chest, using his claws to tease through the thick fur. His hips pumped steadily, heavily, dragging his hard shaft in and out of the cheetah's tight ass.

The black panther wanted even more. He gripped the back of Vincent's neck and twisted, locking the cat into place. Vincent managed a strangled yelp as Shakal forced him down over the desk, chest on the smooth wood. Papers flew off, the keyboard clattered to the floor, and a small snow globe - a present from the company for ten years of service - broke on the rug as the muscular feline leaned over Vincent, slamming his hips deeper, harder.

The cheetah twitched, pushed back, and yowled when Shakal released his neck. His ass clenched tight around the thick length probing his guts and his own shaft throbbed against the side of the desk, pointing almost straight down as Shakal humped him. Shakal, for his part, kicked Vincent's legs farther apart and bent over, opening his muzzle and biting down on the cheetah's shoulder, claiming him as only an alpha feline could.

For several long minutes, the only noise in the room came from the pounding of Vincent's hips against the desk. Shakal fucked him mercilessly, pounding his ass heavier and harder by the moment. He leaned back, claws raking down the cheetah's backside as the smaller male squeezed even harder, tight and hot around his aching cock. This was even better than he'd planned - the cheetah couldn't stop from slutting it up and grinding on his pole.

"Mmmph... gonna... cum!" Shakal gasped. His grip tightened on Vincent's hips and he bounced his broad pink cock in and out rapidly, withdrawing nearly completely with each sloppy, wet thrust.

One final time, though, he shoved in and held himself there, one leg lifting, knee on the desk, both paws gripping Vincent's hips, palms nearly touching in the center of his skinny backside. Shakal grunted, bit his lower lip, and exploded deep within the feline.

Vincent cried out, tongue curling, eyes shut. His cock shot sticky loads of cum against the side of the desk as he climaxed automatically with the other male. The heavy body pressed down on him, pinning him, holding him tight. His small chest rose and fell with rapid breaths as the never-ending climax continued.

Eventually he came down from his unnatural high and collapsed onto the desk, exhausted and spent. Shakal growled and rubbed the center of his back as his hips jerked back and forth a few times, grinding his seed deep into the male's body.

"Mmmfff... fuck, Vincent... you are so tight," he growled. "I'm really going to enjoy the next few months..."

"What... what happened?" Vincent asked, slurring his words slightly.

"The libido controlling drug is working exactly as planned," Shakal purred, leaning over to nip at Vincent's ears. "You're going to feel a growing need, stronger by the minute, until you can think of nothing but getting fucked."

Shakal grinned and pumped his hips a few more times, grinding his half-hard length in and out of Vincent's messy hole before continuing.

"Your body is craving male sperm, essentially. You're an addict now, and you can only be satisfied by fucking and sucking any male you can get your hands on," Shakal said, a villainous note underscoring his words. "Fortunately, we have a solution for your problem."

Vincent tried to speak, ears back, eyes wide, but Shakal interrupted.

"You see, we have drugs that also work in a different way. They can make you hard and ready to go within minutes of release," the black panther explained.

He leaned over the panting cheetah and reached into the desk drawer, pulling out a small case. It flipped open and the black cat showed Vincent a half-empty bottle of light purple fluid.

"As you can see, I injected myself just before you signed the final release forms."

Shakal's voice dropped a note as his cock throbbed, stiffening into total hardness once more inside the moaning, squirming cheetah.

"For the next three months, I'm going to fuck your brains out every hour, on the hour... for science."

The End
