The Naked Tiger stood like a nervous solider on parade, as Gruff looked him up and down with his ever-critical eyes.

"Right !, hop up on da table, FACE DOWN !" commanded the powerful Grizzly, pointing to the gadget laden massage table of sorts. Apprehensively Arden did as he was told, and clambered up onto it. The table had a form fitting body shape built into it's padding, which the Grizzly had adjusted from Cassius's build to fit the Tigers less muscular shape. Arden then noticed, there was a round hole cut in the middle of the table !.

"That's for your SHEATH !" muttered Gruff, "Just stick your Cock down it, don't worry……it won't CUT it off, there's a hollow space for y' balls too".

Swallowing to himself, Arden let his Maleness worm its way into it as he laid his hips then chest slowly down onto the table. Suddenly there was a slurping noise, and a vacuum sharply tugged at his Cock, pulling it firmly down. A seal closed around the base of his maleness insuring it kept a good firm suction upon it, he then felt the same sensation on his scrotum.

"I'm guessing that's one body part you want worked on !" added the Grizzly, "I saw the way your eyes went wide, when ya saw Cassies….all you need is another few inches and some extra girth to get one like his !, here at ma Gym, we feel it's important t' have a Big Cock an' balls so it'll be in proportion with the rest of your Muscular physique !!".

"Y…Yes….." panted the startled Tiger, as the Vacuum slowly increased, he could feel some lubricant being released inside the cylinder which now encased his Tigerhood.

"There's some EMS contacts built into the table as well, a little like the set up you tried yesterday, that's why I have to strap you down now, t' ensure a good contact with them !". As the Grizzly spoke, he brought out some thick Leather straps from underneath the table, and proceeded to tightly bind the Tigers waist, upper and lower arms and legs, and neck securely to the table."Now, I've picked a programme to pre-exhaust your Muscles a bit, it'll basically give you a feel for it….Now, you'll notice a TV screen down at ma feet, there…that's to give you somethin' to watch, in case you get bored".

"Tell him about the "Other" extras, Daddy Bear !" Arden could hear Orsino squeal eagerly.

"Well, OK….. Some of the optional extras are a mechanical Dildo to ram in and out of your Tail hole if you fancy some of that, an' the bar stool in front of you, is for if you'd like someone sat in front, so you can suck on their Cock while the machine does its work!".

" 'That's got an optional rutting Dildo built into it, for if the suckee wants it up the arse at the same time !" added Orsino.

"ALRIGHT CUB !" bellowed Gruff, pretending to sound a bit angry, "Get your cute lil' butt in that Jacuzzi….Daddy Bear will be in there in a minute !".

"Right then, Arden…you' QUITE sure you're ready for this…..?, I've set the EMS for a Pre-exhaust programme like I said, as you've not yet been in da Gym this morning, a DVD will start playing on the TV screen giving you somethin' to watch, normally I'd recommend you visualise the Body YOU want ! as I told ya before, or watching a DVD of a Body Building contest to help with that, but I expect whatever Cassius has left in da player will be much more enjoyable".

"OK !" the helplessly bound Tiger groaned, the sensation of his Cock being stretched by the vacuum was maddening.

A button was pressed, and the familiar tingle of EMS targeted the major muscle groups on Arden's body, the blue screen on the TV monitor changed as the DVD started to play. "Anal Alsatian Antics" came up as a title on the screen, "You'll NOT believe what he takes under the tail !" scrolled across the screen, then the camera panned across the groins of various Furs, who's Cocks went up in size from average to the down right massive. Just then, the suction on Arden's Cock released, no sooner had his maleness shrank back a little when the vacuum returned, released then returned, it was mechanically milking him, he felt a massaging sensation on his balls as well, then more suction as they too where stretched a bit more.

"Fun, HUH ?" he could hear Gruff retort, as he stripped off and headed off to join his "Cub" in the ample Jacuzzi nearby. "It won't let you CUM though !". Arden just moaned softly, groaning at the exquisite torture. He could hear the slosh of water as Gruff entered the Jacuzzi over to one side, he knew the rugged Grizzly was keeping an eye on him, so he didn't feel too scared as his whole body was at the mercy of the machines ministrations.

"Just do your best t' RELAX, an' "Enjoy the ride" !" he heard Gruff call.

The Tiger unscrewed his eyes, and focused on the monitor playing the Porno DVD. A heavily muscled Rottwiller and Great Dane were securing a struggling Naked Alsatian to what looked like a Saw horse. They both held him in place and secured his arms and legs to the wooden trestle, the dog's tail was brushed up out of the way onto his saddle marked back and bound along with his slender waist with another leather strap. "This'll stop your pitiful whining !" snarled the naked Rotwiller as he pried the helplessly bound canines jaws open, crammed a thick rubber ball gag into the German Shepherd's mouth, then secured it in place with a Brown leather Muzzle which he buckled tightly. The hardcore "Scene" got Arden SO hot, that he felt he was about to climax any second, he writhed in his bounds as little as they would allow, as he felt the feeling building within his balls, then….Nothing !. The machine had somehow sensed it approaching, and the suction abruptly stopped, leaving him with just the tingle of the EMS. Arden let out a heavy sigh of pure frustration, what Gruff had said was true !, maybe it was to help with the enlarging of his genitals?. After a few minutes, after he was "Past" cumming, the machine sprang back to life sucking and stretching his cock back to an achingly hard erection inside the cylinder and expanding his ball sac with suction once again. The Tiger was about to renew his interest in the DVD, when he heard some approaching footsteps.

"How's our "Patient" ??, I just came to see how he's getting along before going in the Gym !", Arden recognised the voice as Cassius, the Lion.

"He..s…FI…NE….!!" came the booming voice of Gruff, through clenched teeth, judging by the splashing noise, he was probably screwing Orsino, faint moans and whimpers where coming from that direction, but Arden couldn't move his neck enough to see, he could look straight down at the monitor, or up to the stool in front of him.

"How's it going, Arden ?" he heard the Lion retort, as he took his place on the aforementioned bar stool, "Hope you're not TOO comfortable, because that's my "Bed" for the night !".

"Your BED !?", moaned Arden, as the naked Lion's Cock, glistening with Wolves spittle waved like a hypnotic metronome in front of his nose.

"Yeah, I'm spending whole nights strapped into that thing, with the EMS on low, I've gotta be beyond BUFF for my upcoming Comp' you know….I also…Oh you POOR THING, you're not even using the Dildo attachment!".

"Errr, yeah…..I guess……" quavered the helplessly bound Tiger.

"Would you like my Lionhood, parting those sweet butt cheeks of yours?....I could get in some good "Press up's" practice at the same time!" Cassius whispered tantalisingly into Arden's ear, "Or I could just sit here and let you taste me……". The Tiger grimaced, as the table once again sensed he was about to climax, and stopped what it was doing to his maleness until the feeling passed.

"I'll take that as a YES, then…shall I ??" breathed the statuesque Lion, idly playing with his half hard member.

"THAT'S what…..happens…when you get…..TOO much Testosterone coursing through y' vein's…." Arden could hear Gruff advise, between fuck strokes.

"Please…." pleaded the sweating Tiger, not being allowed to Cum was driving him to the brink of madness, "Please FUCK me hard up the arse….I can TAKE it…..ALL of it….I'm sure !!".

"Well, how can I refuse such an invitation as that…..", the muscular Lion climbed off the stool, and clambered up on the table, putting his hands and knees astride the tightly Leather strapped Tiger. Arden sighed softly to himself as he felt his tail being gently brushed to one side and the Lions six pack and large pectoral muscle's press against his back, teasing him. It was then the Cock and ball stretcher sprung back to life, hungrily tugging at his genitals once again. But Arden's mind was on the Lion's now iron hard erection, which was probing between his buttocks, searching….. Cassius's rubbery Cock head made contact with Arden's puckered anus, and the Tiger drew in breath mentally preparing himself for what was to come. Arden caught a glimpse of the TV monitor in that instant. On the screen the dominant Rottwiller had finished fucking the bound Alsatian, harshly…and the Great Dane was about to take his turn !.

"UUURRRRGGGGHHHHHHHHH!!!!" groaned the Tiger, as without warning Cassius firmly skewered him on his ample Lion cock, lubricated only by wolves spit, and then slowly withdrew leaving just his cockhead inside, holding the Tiger open… ready for another lunge !.

"Alright ??" breathed the Herculean feline, a little concerned.

"Ye..yes…I'm fine…..'just not done it… in awhile" breathed Arden, as he had the ongoing dual assault of the Cock and ball stretching and EMS to contend with at the same time. Cassius made a few slow practice strokes to "open him up", his cock burrowing deep within the restrained Tiger, nudging at his second spincter too and bore past it, deep within Arden's bowels.

"Ready now ?".

"YES !" spat the Tiger, purposefully. He couldn't believe the beautiful Lion who was built like a Greek God, would want to fuck someone as lowly and average as him, the Tiger thanked his lucky stars he'd happened upon such a wonderful Gym with such "Personal service". Arden surrendered his body totally to the Fuck, relishing the feeling of the unrelenting large feline Cock pistoning in and out of him. Continuously, the Lions six pack and large pectoral's pressed against his back as his body made contact between strokes, his large balls bounced against Aden's rump as well, they where full and aching for release.

" 'Thought someone better take t' "Safety" off….!", Arden heard some lumbering footsteps approach. Looking up meekly he saw the massive wet naked Grizzly, with Orsino still impaled on his ample cock, he was held securely in place with one of Gruff's heavily muscled arms around his middle. Some thick white cum was dribbling out of the Cub's vastly stretched tailhole and trickled down over the Gym owner's huge balls.

"This'll turn off the sensors an' allow you to finally CUM,…now OPEN WIDE !" boomed the powerful Grizzly. Arden sensed a button being pressed, and did as he was ordered. With a thrust of his gigantic hips, Gruff bolted forward and the Cub's cock was crammed into the Tigers open jaws.

"NOW SUCK…..HARD !!!". Arden didn't need much encouragement, as he'd never been so intensely aroused in his life, and eagerly began to suckle on the younger Bears Cock, like a new-born at it's Mothers teat.

"You TOO, CUB !" Gruff commanded again, he had drawn a thin tube up from under the table, and held it expectantly in front of the other Bears muzzle. "Fair exchange is no robbery!!".

Arden's head swam, he felt he was going to pass out from the sensory overload!. He was rendered completely immobile by unforgiving Leather straps, totally at the mercy of a Muscular Lion who was pounding his tailhole like a jackhammer with his lengthy feline maleness. Mild electric shocks were attacking nearly every major muscle in his body, his Cock and balls were being milked and stretched by an unrelenting vacuum, and to top it off, a thick Bears cock was now tickling his tonsils. The groans coming from the younger Kodiak Bear indicated he was near climax. His "Daddy" Bear was fondling his "Cub's" balls, and ruffling his chestfur urging him on as he gave him the occasional trust from the hips to remind him he was still very much impaled upon and a prisoner of his "Daddies" substantial Cock. "Arrrrrgggghhhhhhhhhhh" grimaced Arden as he was finally allowed the mind blowing climax he had been aching for. The milky fluid was pumped up the thin tube and shot into the younger bear's muzzle.

"Drink it ALL up, theirs a GOOD Cub !" crooned the gigantic Gruff into Orsino's ear, that was all it took to send the sucking cub over the edge, and his own cock spat his balls contents into Arden's muzzle, which the tiger swallowed gratefully. "DAMN, that's HOT !" snarled Cassius as he watched the double climax, "I'm n…n…ext…Urrrgggghhhhhhh!!!!!" he groaned as he gave one last hard thrust from his hips, injecting his own creamy load deep into the Tigers bowels, after a few seconds he mustered up a second and third and humped them in too, "I….guess….that's ONE…doughnut…..that's truly got…..it's CREAM filling" groaned the Lion, as he recovered.
