#1 of Gifts

FruitzJam recently designed two new really stylish OCs, and I felt compelled to write a piece about them! I feel like it's kind of rare to see cheetahs, much less ones that have a tired-looking or gloomy disposition like Madlov, so I near instantly fell in love!

This is actually my first NSFW piece (and, honestly, first actual piece in a long while), so I hope the, er, sexy bits aren't too cringey lol. I'd appreciate any feedback and comments!

And, obviously, as a disclaimer, both Madlov and 6E are owned by Fruitz. This was written as a bit of a surprise gift, so I had no input from him on any of this; therefore, please take this with a grain of salt in regards to his own characters ????????

Please check out his SoFurry and Twitter accounts, not only does he do art, but also writing of his own!https://twitter.com/FruitzJamhttps://fruitz.sofurry.com/


"...Mhm...."

The sound of a cellphone vividly vibrating, moving across the wooden desk as it was carried by the recoil of its own ringing upon the smooth wood filled the room, that had previously been completely silent, if not for the rather quiet snoring coming from the cellphone's owner--Dr.Madlov.

A male cheetah in his late 20s, who sported a slim athletic build as would often be expected of his species--and a rather gloomy disposition, showing itself through his complete detachment towards most things, that was the complete antithesis to how his kin would usually behave.

His upper body laid his desk, having passed out on it in the late hours of the night before. He was in the middle of work, and as such in front of him was his laptop--to the sides of it, an overwhelming amount of unsorted papers, cluttering the space. And, having escorted itself all the way to the edge of the desk through its own vibrations, was his own ringing phone, which was about to fall.

"Oop. Not so fast." Madlov mumbled as he caught it just as it was about to pull a Hail Mary and jump off the desk in search of lands unknown. He took a look at the phone's screen--it was his manager that was calling. Given how the phone had been ringing long enough to drag itself all the way to the end of the desk, chances are he'd been desperately calling for a while now. Madlov swiped his finger across the device's screen to accept the call, drowsily holding the phone to his left ear with one hand, as he rubbed his eyes with the other.

"About time you picked up! Would it kill you to keep that thing off silent every once in a while?" His manager asked from the other end of the line. Madlov could see the man most likely rubbing his temples, pacing back and forth around his office after having waited for so long.

"M'bad. I just woke up. Did you need something?"

"Yes! You still haven't sent me your report on your monthly progress, and the executive meeting is today. I don't care if you have to make something up, but I gotta have something to show to the execs."

"Oh, right. I haven't really had the time to write that."

Madlov heard an incredibly heavy sigh from the other end of the line.

"Don't bullshit me on this. Not only do you have a full month, but you're the one who dictates your own schedule. You just didn't give a shit, did you?"

"Guilty as charged."

Another incredibly long sigh.

"Look, fine. Whatever. Can you at least give me a rundown on what projects you've worked on this month, or anything that'll be complete in the near future?"

"Let's see... for the same old, some of the performance-enhancing formulas I was working on are pretty much done. We've confirmed they're undetectable, so no need to worry about athletes getting caught on their screenings. Just focus on that."

"You already had me use that as a cover last month. Give me something new."

"Did I? Hmm." Madlov laid back on his chair and made himself more comfortable than before, now scratching his chin as he tried to think of anything his manager could use to keep the executives funding his tools and supplies.

"I basically spent this entire month working on Sissy, and he's shown some considerable improvements in comparison to before. He's more active and shows more awareness than ever, and his cognition--"

"Who the hell is Sissy?"

"Test subject 6E, the one I was working on before."

"You can't possibly still be working on that! Madlov, you know we're not exactly the most upstanding research institute out there. If one of your projects is getting you called 'Mad Scientist' by researchers whose jobs are to help execs cheat the law, you're probably going a lot farther than you should."

"Well, I do take some issue with the nickname. I'm quite well mentally, so 'mad' isn't really the term I'd use. I'm just eccentric." By this point, Madlov had gotten up from his chair and left the phone on speaker on top of the desk, as he stretched to wake himself up. "Anyway, I don't really care what the others around here are saying, and the execs are stuck with me whether they want to or not, so I don't get why you're panicking. I could spend the entire rest of my research funding on luxury cars or hookers, but here I am toiling away on something that happens to be niche. It'll pay off later, so don't worry about it."

"Madlov, your test subject may have been on death row, but he's still a real person. You can't possibly be serious about going through with this research." His manager tried to speak to him in as serious of a tone as possible, forgoing the previous topic surrounding the executive meeting and trying to focus on the long-term future of Madlov's research. The moment the both of them got involved in this institute they knew they would be in a full breach of ethics, but he always thought that the doctor, as uncaring as he may have been in regards to the world they threw themselves into, would never willingly go out of his way to research such things. And yet...

"You can't be seriously trying to preach to me at this point. You hire me to develop drugs to cheat on tests and competitions without getting caught, modify other drugs so that they're cheaper to produce and easier to cause addictions, and finally, we're both stuck here for life under a vow of secrecy lest we get silenced, and now you want to preach about morals? Come on. Do you want the details so you can make a presentation for the execs or not? I don't care either way."

...It was clear to the manager that Madlov had finally grown annoyed with all the questioning. Like it or not, he wasn't essential to this company, while Madlov was. And his one and only job was to report on the doctor's findings. He wasn't paid to argue about it, and he certainly didn't have the position in this place to do so.

"...Fine. Run your results by me." The manager sighed for the third time this call, feeling as if he had admitted defeat.

"Good. I don't remember how many details I gave you, but long story short, Sissy's rehabilitation surgery was pretty much successful. The man that had once been a murderous psychopath is now gone, at the cost of some of his basic abilities, such as reading or writing, handling tools, and whatnot, though that's easily fixable. Right now, I'm currently experimenting to see just how moldable a subject with previous behaviors as extreme as his can be." Madlov started speaking faster, finally interested in some part of the conversation that they were having.

"For the execs, what this means is that in the future, reshaping the lifestyle of people that cannot be rehabilitated is a possibility. Of course, not as a member of society, but as servants or some other kind of worker, since it'd be too much of a hassle to keep their previous personality and cognitive functions." He grabbed his phone from the desk, turning off speaker mode, and putting it back to his ear as he left his office and walked down a long, white hallway, truly reminiscent of a sanitary and near immaculate place such as a hospital or research institute.

"Since obtaining subjects for this kind of thing is a hassle, I'm prioritizing focusing first on one subject before branching out to another, and getting as much data as I can. From the reports I have on Sissy's previous life, it seems he was rather selfish, and practically incapable of demonstrating affection or feeling empathy for another, so I'm working on those aspects with the view of repurposing him as an assistant of some kind to the elderly or disabled, or maybe just some kind of companion to lonely rich people." As he walked down the hallway, he approached an enclosed glass space containing the subject he spoke of--6E NM-L.

His "room" was rather large, and furnished with a variety of different objects, all of them serving a different purpose--from training weights, to exercise balls, to even large plushies and other things, along with a large bed (which seemed to be nearly broken), a sink, and a toilet. It notably seemed to lack a shower or bathtub of any kind--most likely due to the large size of the subject and his unwieldiness, deeming it necessary for Madlov to bathe him himself with a hose.

"...I see. I get what you're going for." On the other end of the line, Madlov's manager gulped and swallowed his own pride, deciding to go for it. "I'll try and focus on this as a future investment, maybe an alternative to AI companions. I disagree with this, but... I have a feeling the execs will like it. I'll notify you if anything interesting pops up during the meeting."

"Mhm. Thanks." Madlov replied curtly, as his subject, which had previously been sleeping, seemed to have had heard his footsteps and turned to look at him through the transparent glass walls of his room, salivating as he eyed the doctor. He was most likely "hungry" already, despite getting a good fill the previous night.

"Just one thing, doctor." Madlov's manager spoke out right as the cheetah was about to end the call. Given he addressed him by his title rather than his name, he figured it was probably serious enough to warrant not just hanging up on him right then and there. "I already know well that you can handle yourself, but... even if he's just a test subject to you, and he might have undergone intense surgery, remember--he's still a previous death row inmate."

"Huuh, now that's something. You concerned about me?" Madlov expressed his surprise in a completely deadpan tone. Although he wasn't going to take any of his manager's advice to heart, he was curious on what exactly prompted this.

"No... well, maybe. I don't know." His manager had most likely started rubbing his temples again. "I feel as if it's not just you that's in danger here, honestly. I know you don't give a shit, but I don't have a good feeling about this... that's all. Well, I'll be seeing you later. Bye." The call ended before Madlov could even reply in any way to him. He found that way better--it's not as if he had anything in particular to say to someone's superstition. He had a job to do, after all.

He undid the security locks on the door leading to 6E's living space, and calmly entered it. Obediently waiting for him with a famished look on his face was a tiger man nearly twice his size, with a strong, toned body. The acronym "6E" and "NM-L" were each engraved on the left and right parts of his ample chest, respectively. Scars were present on a few parts of his body, not due to the surgery, but from his previous life--cuts of various sizes, which, despite being partially obscured by his dark fur, were still very much visible if one got close.

The test subject wore no clothes at all, with the exception of a chained collar that had been attached to his neck, along with two iron bracelets attached to his wrists, the chains of all three being attached to different parts of the room. A small light on the collar shone, indicating it was active and ready if needed to electrocute its prisoner due to any misbehavior.

And yet, none of these security measures felt necessary, as Madlov approached his lovingly nicknamed "lab animal" and caressed his cheek with a gentleness that seemed unbecoming of someone like him. 6E reacted accordingly, rubbing his large cheek along to Madlov's hand, his large matted cheek fur barely being squashed. The cheetah's hand then went further down, caressing 6E's chest, until he finally pulled his hand back into the pocket of his lab coat.

"Mmgh...ngh..." 6E groaned as soon as the doctor stopped caressing him, seeming displeased. He approached the doctor as much as he could with the chains binding him, his nose barely touching the side of the cheetah's neck--sniffing it much as one would take in the scent of a flower. He then licked that part, making Madlov recoil a bit in pain.

"To think just the pressure of your maw kissing my neck somehow injured it last night makes me wonder if you were ever really human to begin with." Madlov spoke to the creature in front of him, who most likely couldn't comprehend any of it. "Even the largest carnivores don't have a physical build like this anymore. The drugs helped, but you were already ridiculous to begin with... other than your muscles and your dick, I'm pretty sure nothing else grew due to me. This ridiculous height is all yours, at least."

Every time he visited 6E, he eyed his body from top to bottom, as if he were appreciating some kind of wonder of nature. He wasn't exactly a looker in facial features, instead having a rough look to him, with a large, wide head that seemed even wider when taking into account the fur on his cheeks. It wouldn't be strange to confuse him for a bear due to how his ears seemed almost completely circular, due to being partially obscured by his head.

His neck was thick and just as strong as the rest of his body, with notable veins and ligatures showing whenever he extended his neck to sniff Madlov or take a look at something. His torso seemed downright oppressive to anyone around the doctor's height, his wide back and large pectorals seeming as if he could easily crush your entire body if there was any flat plane between you and him.

Naturally, the same went for his limbs, with arms that had surely participated in their fair share of feats to award him with a front row seat to the electric chair, and toned legs that helped him chase those who would fall victim to his arms. Viewing it all as one package, it was almost unfair--he could see how this man had ended up as a death row inmate, being blessed with such power by simple genetics. His herculean body had most likely factored well into his upbringing--having such an easy answer to life's problems with it must have been an offer too tempting to pass up.

...And all that only served to make Madlov more excited as he inspected this man's body freely. Sure, he had woken up just a while ago, so it could just be morning wood--but given that he felt his dick getting hard whenever he looked at him, he could hardly blame the morning wood this time. That was without even getting into 6E's own penis, which had been proudly standing alert since the moment 6E saw Madlov today. A meaty, veiny, and quite frankly barbaric-looking thing, seeming unfit for any kind of pleasure. And yet...

"Seems like the drugs are still keeping your libido on 24/7, huh? Or maybe it's just your natural disposition?" Madlov said out loud as he got closer to 6E and crouched down, lightly slapping his dick with his index finger over and over, watching it wiggle. "Not that I can complain. I'm the same, and I'm not even taking anything."

"Rrrgh..." 6E moaned as his dick was played around with. Not even a few minutes in, and it was already leaking some amount of precum. The rising of his body temperature was apparent, as each breath 6E took was as if Madlov got blasted with a wave of hot air. His large chest, heaving in and out, seemed like some kind of optical illusion, the doctor unable to take his eyes off it.

"Do you like it?" Madlov asked as he approached the tiger and voraciously grabbed his chest, almost as if he was clawing at it. The hard feeling of muscle beneath the soft skin and fur, the heat emanating from it, intoxicated Madlov into playing with it even more, pinching his test subject's nipples with force. "Come on, now. Won't you respond? Sissy."

"Ohh...hhgh...aaah..." The test subject moaned out, his tits being played with as roughly as Madlov could muster. Despite all that, the cheetah's deadpan expression didn't seem to change one bit, however, even with the taunting coming from him. His body reacting to the stimulus, he pulled Madlov closer with one of his hands by the butt. Although he could feel some of it, the cheetah's soft furry butt was obstructed by not only his pants but also his lab coat--and so, as 6E pulled Madlov closer to him, the cheetah's face on the tiger's large chest, and the tiger's penis rubbing between the cheetah's thighs, he ripped apart the lab coat by grabbing the collar with two fingers from each hand and pulling it apart much like how one would with a bag of chips.

The leftover fabric from the back fell to the ground, with just the remnants of the sleeves still being stuck on Madlov's body--though he removed them shortly after. He sighed a bit at the waste that had just happened, but with the desire both him and the creature in front of him were feeling, the circumstances seemed completely irrelevant. He decided to remove his belt and take off his pants before that got ripped apart, too--leaving him wearing only his black button-up shirt and underwear.

His bulge was pretty pronounced--although he wasn't some kind of size demon like 6E, he was definitely a grower of intense proportions when the ideal situation aroused him like this, and he could feel himself wanting to remove his underwear as fast as possible. But, for the sake of his research, as well as better foreplay...

"Come on. Don't you want to take this off me, too?" He enticed the large tiger in front of him, massaging his pecs, kissing and biting his nipples and the side of his neck, all the while slowly inching towards the bed near the corner of the room. And, as if somehow getting the hint, 6E got up just the slightest bit from the ground, so that he could walk a bit forward, pushing Madlov with him towards the bed.

Madlov imagined the feeling of 6E pressing onto him and pushing him from the middle of the room to the corner, and right into the bed, with nearly no effort--just by walking forward and not minding the cheetah in front of him--was much like how American football or Rugby players felt... or perhaps victims of a truck accident. And yet, this felt entirely comfortable to him, the tiger's body temperature and fluffy, if a tad dirty, fur intoxicated him. Even the smell was starting to get to him, much like an aphrodisiac.

"Rrghh..." The test subject grumbled after pushing Madlov onto the bed, facing him. He caressed the cheetah's legs--surprisingly toned, as would be expected from a cheetah, despite Madlov's choice of profession. They were a bit cold from the time he had spent in the cold office and hallways of the institute, however, which was welcome to the ever hot 6E, who carefully grabbed them with just the smallest amount of force, to feel their cold--and just from that, the cheetah groaned as if his legs were being crushed, and suddenly 6E stopped.

Madlov took a mental note of this, wondering about the concern that 6E had just shown towards him, but then beckoned for him to continue. They weren't done yet, and neither did he want them to be done anytime soon.

6E, then, put his hand to Madlov's stomach, under his button-up shirt. Unlike his legs, his stomach was a bit warmer, and as his hand went up to his chest, it seemed to get even warmer, with a fluffy tuft of fur smack dab in the middle of the cheetah's pecs. 6E put a bit of pressure on his hand, caressing Madlov's chest, and, uncharacteristically... he moaned, breaking the poker face that he had from the start of their interaction.

From that, 6E's dick twitched.

Madlov had no idea how 6E envisioned him, exactly. As a master, a lover, or something else--but, what he did know, was that 6E didn't lack in desire. But especially so when he could see some kind of enjoyment, vulnerability, emotion, on Madlov's demeanor. He wasn't sure if it was some kind of sadism, or just the enjoyment one gets from seeing someone react to one's own actions--but it was then and there that he knew he most likely wouldn't be able to just walk away after this.

6E pulled his hand up with force, ripping apart Madlov's shirt and the buttons that were holding it down. The cheetah was now left only with some pieces of cloth that used to be his sleeves around him, and his underwear--though that too didn't seem as if it would last much longer, as 6E had his eyes on it as if it was his prey.

Without wasting a single moment, 6E shoved his face right onto Madlov's bulge, sniffing it, licking it, savoring it--all through the underwear's cloth. The smell of it seemed to drive his excitement even more, as, unlike with the other pieces of clothing that he removed, he seemed to take some amount of care with this.

"Mm! ... Ah..." Madlov moaned a bit as 6E put his nose to the underside of the cheetah's balls, playing with them and rubbing his face on them, edging the doctor even more. 6E had been leaking pre for quite a while now, but Madlov had only just started--and yet he didn't seem to be too far behind when it came to the amount, almost as if he was pent-up, despite their encounter the other night.

6E finally took off Madlov's underwear, however, first pulling it down just the slightest bit so that Madlov's dick would be visible, letting himself lick the top of it and taste the parts that had already come out of the foreskin. After he played around with it a bit more, bobbing his head up and down rhythmically to suck on the head of the penis, he finally became satisfied when Madlov's body reacted, his hips thrusting forward and his teeth biting down on the lower part of his mouth as a sizable amount of pre leaked from his dick. He had grabbed the bedsheets with as much force as he could to prevent himself from cumming right away.

Now that his underwear was out of the way and not only the cheetah's dick, but also his ass, were fully visible, 6E lunged forward, lifting the doctor's legs up so that he laid only on the upper part of his back--his asshole now up. Without standing up, however, it meant 6E would have a hard time thrusting anything into it... Madlov quickly realized what the test subject was about to do, and relaxed himself. It was one of the best parts of his encounters with this beast.

6E licked Madlov's taint, slowly getting to his asshole, teasing the outsides of it with his tongue. He seemed dedicated to doing a thorough job, almost as if he was giving a gentle tongue bath to the doctor--until he finally put his tongue in, and Madlov moaned, his body reacting to the stimulus. Even more pre leaked out of his dick, dripping down from the head into his chest due to the position he was in.

The doctor's instincts felt as if they conflicted with each other, unsure of whether to grab the bedsheets with force again, to play with his own nipples, or to jack himself off as 6E teased his hole. Even his dick caused less reaction than this, since at least its force and thrust rhythm were predictable--but the tongue? The way it went all over the place was too much. As if he was asking for mercy, he caressed 6E's leg, which was bent near him, trying to reach for his dick.

6E, removing his face from the doctor's genitals for a bit, looked at the doctor's contorting body and took the hint for what he had to do next. Lifting his legs up yet again, he slowly put his dick inside the doctor's hole--it was now 6E's turn to moan, as he felt his dick pulsate inside the doctor. Before, he could focus on the action so much that his own dripping cock didn't stop him, but now, he felt as if he was the one getting fucked, despite it all.

Not being able to handle it, 6E lifted Madlov and pulled him close towards his chest, the doctor's dick and balls flopping up and down with each thrust--and the doctor, too, could feel 6E's balls slapping his asshole. Not long after, both could feel the other was about to hit their climax--the doctor felt 6E's grip tighten on him, the pain causing him to moan, and that only aroused 6E even more. Soon, the two came--6E inside Madlov, and Madlov on himself, his semen getting to his stomach, face, hair... and finally, 6E slowly removed his dick from inside Madlov, although he kept spurting a bit more as he did so. He then pulled him close one more time to "kiss" the side of his neck, much like he had done yesterday--but with a force so strong that it couldn't help but leave a mark, despite not using his teeth.

"H....aaaa......Haaaa......." The doctor tried to regain his breathing as he laid on 6E's bed, taking in his smell, the smell of cum, and overall everything that had just happened. "...Phew." He lost track of how much time he had spent laying there. It could have ranged from 30 seconds to even 10 minutes, and yet he was completely unable to discern it--but as much as he wanted to keep laying there, he knew he had to note a few things down before he forgot. He struggled to get up from the bed and make his way to the door, supporting himself on the walls along the way.

As he was about to leave, he looked at 6E, who was laying on the floor, having passed out there instead of on the bed. Could it be that he understood that, were he to lay down on top of Madlov, he would surely kill--or, if not that, at least injure him? Along with some of the concern the beast showed during the foreplay, Madlov took it all into consideration as he left the room, reactivated all of the security measures, and went out into the hallway, making his way back to his office. He was lucky this entire ward was effectively his territory--though, given what he knew of his reputation, he wouldn't have minded the other researchers taking him for a perverted nudist as well.

Once he finally got to his office, stumbling there from the pounding he took, he sat down on his chair, grabbed his notepad, and began writing down some of the observations from just now before he forgot. The small bits of cum dripping from his hair into the notepad didn't particularly bother him.
