William pushed the wolf back into a sitting position, and admired his cock, now rock hard and gleaming with his spit. He placed his thumb at the base of the shaft where his sheath sat tucked neatly, and held his forefinger at a right angle. At his best estimate, the canine clocked in at 9" long, a good 6" around, and a knot the size of his fist flared needily at its base, throbbing with its need to rutt after a good, long teasing.

"Yes, right, you'll do perfectly," he said, reaching backwards and pulling a plastic cylinder from the backpack propped up against the side of the bed. The grey tube was filled with a kind of gel, and the words "WOLF, XL" shone in permanent marker shone in the lamplight. His partner's face, with his dark green eyes and rough beard, registered a mix of confusion and annoyance.

"Look," he said through gritted teeth, "I'm not interested in fucking no toy. I came here because I wanted a piece of that tight ass, lion boy."

William barely recognised his protests. "This is, uh, an invention of mine. It's important to test it on fringe cases, you see." Without missing a beat, he pressed the opening of the cylinder against the wolf's aching shaft. "In the club I could see that you were of, uh, excellent endowment, and I had to ascertain the suitability of-"

"Look, either put the toy away and sit on my dick or I walk. I don't have time for this sh-"

The words were cut off by an involuntary moan as William pushed the toy firmly onto his shaft. He knew it would feel good, incredible even. It slipped on effortlessly even without lube, and gripped the canine shaft in all the right places. As William began to slide the toy over the wolf's cock, he stopped protesting entirely, leaned back and let out a happy sigh.

"Perfectly contoured and molded for the canine anatomy, one of a series I'm working on," William continued, "Should be better than any ass you've ever fucked, honestly."

The toy began to squelch with the wolf's pre, and he managed a breathless nod, his muscular chest heaving with delight as the cat worked his magic.

"Plus, being tailored for canines, we can do this-" he pushed the toy down, and the wolf's knot slid firmly past the gel with an audible pop, into a textured section at the base. The wolf bucked his hips upwards and swore. Loudly.

Now tied, the toy didn't move much up and down, so William moved it as much as he could, twisting it gently so the texturing rubbing against the wolf's engorged knot. After a few seconds, the wolf moaned loudly, bucked his hips violently upwards into the toy, and shot his load to accompanying squelch sounds.

William reached for his mobile phone, and snapped a picture of the spent wolf, flopped naked against his bed with his softening cock firmly tied to his toy, a wide grin on his face.

Another successful run, then.

William had different tastes. This is something he'd come to accept. He had a high interest in sex, and a high sex drive, but to his dismay he'd quickly realised that the actual act of sex did nothing for him. It wasn't for lack of trying. At least two or three times a week he'd visit a club or a sauna and throw himself fully into the mindset of a twinky gay boy looking for a good time.

Once he slipped into character, he found it easy to convince people to sleep with him. He was a slim lion, with a prominent brown mane that he took special care of. If his natural good looks didn't snare people, then his flexibility in bed and practised charm would usually convince them. If all else failed, there was always the fallback of letting them get a peek of his large sheath at the urinals. That usually did it.

He'd spent years frequenting gay clubs, hooking up with anonymous partners, and had more sex than anyone in their early twenties had any right to have, but he'd always failed to find the elusive spark he was after. Whether bouncing on a horse cock the size of his forearm, balls deep in a bear or a twink, or even sat open legged in the middle of a club while two naked twin coyotes worshipped his cock, it just never really did anything for him. He enjoyed it, sure, and he even managed to cum most of the time. But it always just left him unsatisfied and wanting more, like it never quite hit the right spot.

It wasn't until he met Markus that he began to realise what was missing. Markus was a cheetah in his late 30s, with an average build and fairly average looks that nevertheless carried a kind of plain charm that William had been drawn to. He'd met him at a coffee shop, where the two of them had flirted shamelessly until William agreed to let the cheetah show him where he lived.

As soon as the two turned into a quiet park, Markus rubbed the back of his neck and turned to the lion following him. "Look, Will..."

"I prefer William." William chimed in quickly, the response almost automatic.

"William. I should probably be frank with you." The cheetah's sharp features changed into a kind of worried grin as he searched for the right words. "What are you expecting?"

"Well, it's up to you. From the way we were flirting I guess I'm expecting to end up on all fours with you rutting me." He made lustful eyes at his host, but in truth his reply was no less automatic than the comment about his name. Markus sighed heavily.

"Look, that's the thing. I find that things go better if I put all my cards on the table here. If you want to leave, I won't think any less of you. If you're wanting me to top then I just... I'm not always able to..." Markus paused, his nose twitching as he lowered his voice. "Perform."

William blinked. "Really? But you're only, what, 40?"

"37. But, I take these meds. I had some issues a few years back. The doctors were able to get it under control for the most part, but thanks to the cocktail of medication I'm on, I just..." he waved his hands in a gesture that was obviously meant to finish the sentence for him.

The two continued walking in silence, Markus almost holding his breath while thoughts whirled through William's head. In eerie silence and with neither of them stopping or diverting their course, they eventually arrived at a small semi-detached home just as dusk began to settle. Markus stopped, reached into his pocket and began to awkwardly finger his keys.

"Look, I apologise for, uh, the remark about your age." William said eventually, ditching his lusty-club-boy persona. There didn't seem much use for it now. "I guess this can't be easy for you. But you, uh, want sex, right? You wanted to have sex with me? Did you want me to penetrate you, or..?"

Markus shook his head. "I'm not into taking dick," he said, taking a deep breath. "But, I could tell you're a decent bloke, right? You've been around and I figured, maybe, you'd get that sex doesn't always have to be, you know..."

"What?"

"Sex?"

Markus hadn't been interested in actual contact, but had instead shown William his impressive display of sex toys. He had a room so full of the things that even William had almost blushed at the site of it. Shelving covered the walls from floor to ceiling, to the left and the front containing a variety of silicone cocks of all shapes and sizes, from respectable buttplugs to statues of dragon cocks thicker than his arm. The right wall held an assortment of different devices - cockrings, e-stim kits, nipple clamps, some metal rods William assumed were for sounding, and fleshlights.

That night, watching Markus masturbate with a crude fuckable toy, William's paw had almost absent mindedly moved down to his crotch. He felt something wet slide across his pads, and jerked the paw up to look at it, thinking himself injured. Instead, a thick smear of pre dripped from his paw. He'd never really produced much pre before, assumedly due to his complete lack of satisfaction from sex. But here he was, not even touching himself, and his cock gleaned with a layer of the stuff.

He reached down, taking his aching cock firmly into his paw, stroking the pre along his shaft in time with his host's motions in and out of his toy. It wasn't long before he felt a powerful force building at the base of his shaft, and before he could stop himself he was howling, shooting thick loads of his cum across the hardwood floor.

He sat down, panting, his wet cock softening in his paw and slowly slipping back into its golden sheath. Several trails of white cum stretched before him, possibly more than he'd ever shot in one load before. And as Markus reached his climax, the naked older cheetah pulling his dick from the toy and shooting over his own chest, William realised that he'd actually, genuinely enjoyed himself.

He'd hooked up with Markus regularly after that, their uncommon shared interest proving enough to overcome the age difference between them. One day, William had arrived with a gift.

"Your toy. The one you, uh, put your dick in?" He stammered. For some reason, whenever he wasn't in pickup mode he found himself far more self-conscious talking about sex. It was like the words didn't come to him unless he was playing the club boy persona.

"The fuckable?" came the seasoned reply.

"Yeah, I was, uh, thinking. Those things are cheap, right? They make them all the same, so they can make them in bulk for the most profit. They're all the same inside. But we're all different, right? We cats have barbs, canines have knots, kangaroos have something going on down there that I've never really understood. But everyone's expected to get off with the same tube with a hole in it, right?"

"I'd never thought of it, but I guess so. How come?"

"Yeah, I was thinking, okay. And I read on how to make your own humpable toy. So I made one. But I made it for us. You know. For cats. For our dicks." And with that, he presented his invention to Markus. It was crude, and looked like something a teenager would throw together while his parents were out, but the crude sales pitch had piqued Markus' interest.

By the end of the night, the two flopped next to each other on the bed, covered in cum from a series of orgasms they'd not bothered to clean up.

"My boy," Markus said, pulling the toy off his spent cock and watching with a quiet admiration as the cum leaked from it and dripped onto his chest, "you may be a genius".

And that was that.

As he and Markus had begun to realise that there was business potential in the toys, they'd both come to realise that they were going to need to start testing the things properly. William was able to model a variety of toys just from the memory of his past encounters, but even he was starting to feel awkward targeting partners by their species just to try out his wares.

His first official tester, that is, not Markus or a random guy he'd hooked up with at a club, had been a coyote named Aethyr. At least, William thought he was a coyote, he may have been a hybrid or a werewolf or a mutt or something. But it didn't matter, the fact is that he was the only one who'd actually answered the ad in the cheap sex magazine he'd decided to use to find test subjects.

It was poorly worded.

But it had worked, he supposed, as the coyote sat down on his couch, his massive frame making it buckle slightly. He wasn't overweight, not in the slightest, but he was simply huge, a good foot or two taller than William. He also wore relatively little, just a cloth vest and a loincloth that flowed between his legs, protecting his modesty. His exposed fur was adorned with tribal paint.

"So, I'm thinking we just get to this?" Aethyr ventured after a moment of awkward silence.

"Yes, yes. Please undress and show me your penis."

Aethyr was caught off-guard by the bluntness of the request, the cold, medical terms only making everything seem more surreal. "Here? I thought you'd just give me the toys and send me to the bathroom or something."

"Yes, here. I need to see which toy you need. They're all tailored for certain species and sizes, you see, and even if I knew your size I'd need a good look to see which toy is best suited for your, uh - mixed heritage? Is that the right way to say it?"

Aethyr shrugged this off, but avoided eye contact. "Look, I'm not sure about this..."

"Please, I just need to test my toys. I won't judge for shape or size or anything, and I won't touch. This is a safe place and it's all just for research."

Aethyr sighed and went quiet. William was sure he was going to leave, but then he did something surprising. He simply shrugged and tugged off the vest, pausing a moment for approval, before untying the loincloth at the side and letting it fall to the floor, exposing his fat sheath. He sat back down on the sofa, subconsciously spreading his legs to show off. Though unaroused, his sheath was pert and stood to attention, and was covered in the same light brown fur as the rest of his body.

William tried to stifle a blush, not that such a thing is possible. He'd seen plenty of naked guys before, of course, but the formal situation had thrown him slightly.

"I'll need you to, uh, harden."

The coyote looked away again, but after a moment his paws wandered down and began to squeeze and tug the cream coloured fur of his sheath until the red spaded tip of his cock began to poke free. As soon as the pre-covered tip slid into view, it was like all the coyote's shyness washed away, and he began to coax it further with his thumb and forefinger. When most of his length had pushed free, William could see the telltale bulge of a knot forming inside the coyote's sheath.

"I'll, uh, need you to expose your knot, too." he stammered, to which Aethyr responded by shooting him an I'm getting to that, already, sheesh look, and moving his paw down to push his sheath back, the red bulge of his knot popping into view. Content that he had hardened as requested, Aethyr returned his hands to his sides and let his hard cock throb unassisted between his legs. William pulled out his phone, taking a front-on shot of the coyote's manhood (eliciting a vague, surprised blush from his test subject), and then rummaged around in his bad until he found "COYOTE, L" and handed it to him.

This particular item was mostly a translucent shade of green, a deliberate design choice so that William could see the inner workings of the toy as the coyote's cock pushed into it. It would have been entirely transparent if William had been able to find the materials, but the faint green tint was all he'd been able to get his paws on.

Aethyr blinked for a moment, shyly taking the tube and pressing the opening against the pre-slick tip of his cock. He let out an involuntary moan as he slid it down over the engorged red flesh, wasting no time in slipping his entire manhood, knot and all, into the toy with a telltale pop.

Much to William's frustration, however, the coyote just stopped. He just sat there on the sofa, legs spread, his balls hanging low below COYOTE, L, which stayed firmly surrounding his manhood like some oversized and useless chastity device.

"Is this supposed to be doing anything?" asked Aethyr, in a tone of voice that led William to suspect he was only playing dumb.

"No," William sighed, "it's a masturbation aid. You, uh, wank with it." This explanation was accompanied by William subconsciously miming the hand motion in front of his crotch, which only really served to draw attention to the tent in his jeans and make Aethyr seem more determined to be as cheeky as possible. He pawed weakly at the toy, moving it mere millimetres up and down, looking expectantly at the lion in front of him.

"Look, I don't think I can cum from this. How about you try putting your muzzle on my balls to help?" he said, with a grin.

"Look, Aethyr, to get usable data from this experiment I can only observe, any interference on my part could contaminate the results by biasing them towards-"

"What if you rimmed me?" he interrupted.

"That wouldn-"

'What if I rimmed you?"

"No, I-"

"What if you just show me your dick?"

"I really can't-"

"Okay, what if you just use the toy on me? As you'd expect me to use it on myself?" Aethyr quickly chimed, eyes filled with hope as this time, William paused.

"Okay. Fine." William relented, and could have sworn he saw the coyote's dick throb happily inside the toy.

Moving forwards, the lion knelt between the coyote's legs and wrapped his right paw around the thick plastic toy, gently moving it along the coyote's manhood. The smell of pre and musk filled his nostrils and he felt his own cock straining against the fabric of his boxers, but determined not to bias the results any more than he already was, he heroically ignored it.

The toy clearly had its desired effect, and despite the trepidation the canine had expressed, he was soon leaning back on the sofa with his eyes shut, his huge balls tensing and bouncing with each thrust, this model allowing the toy to slip loosely over the coyote's knot without tying.

Eventually the toy began to make squelching noises as it filled with pre - a possible improvement needed on the design there, William made a mental note - but the coyote didn't seem to notice, panting heavily as he imagined he was tying over and over with the lion, his knot slipping effortlessly in and out of his tight ass, the sensations hitting his brain not telling him any different. He felt a sudden tensing in his balls, and his knot screamed.

"I got it, I got it..." panted Aethyr, reaching down to the take the toy into his own paw, pulling it up and slamming it down firmly over his swollen knot several times, the pleasure surging through the tense flesh with each motion. Suddenly and without warning he pulled COYOTE L off his cock completely, groaned loudly, and came, shooting thick loads of his cum high into the air and straight onto William's muzzle, who was still knelt between the coyote's muscular legs. To his credit, the lion stayed in place, and by the time the coyote's orgasm had subsided his muzzle was almost completely painted with thick, white lines of cum.

The test over and, as unscientific as it had turned out, a huge success, William leant down to lick the cum from the coyote's spent shaft, eliciting a rough, guttural sound of appreciation from his subject. It just seemed like the appropriate thing to do. And besides, he didn't want to spent the rest of the day cleaning coyote spunk from his sofa.
