The park was, as always, alive with dogs, crowded with wagging tails and leaping canines, barking and yapping and trotting happily about.  I smiled to myself, wearing only a pair of red and yellow undies and red sneakers, my pudgy belly hanging over the waistband, the red fabric tented and stained with precum at the tip.  The amulet hung lightly around my neck, and I had been busy.  The amulet allowed me to edit reality to my liking, rewind and shift time, and nobody would ever notice anything was amiss, even as the situations grew more and more outlandish.  Consider it a parallel universe integrator, if every possible situation exists, the amulet had the power to draw events from any universe and combine them into my local timespace.  It worked like root access to reality itself, giving me powers like Neo in the Matrix, except no agents to get in the way, and I had far more perverse things on my mind.

Only a few humans were present, here in the late afternoon sun, nude and leashed by their collars to benches and posts while their owners, the dogs, ran freely through the grass, sniffing and licking wherever they would.   I moved freely through the park, not invisible, but content for now to have no attention paid to me whatsoever, regardless of what I did.  My gaze landed on a cute little mutt, tail upturned to expose his rump and dangling, walnut sized ballsac, a little bigger than normal for his breed, but my playtime had yet to begin.

I made a little motion with my fingers, and glanced at another dog, this one a sizable Jack Russell terrier.  He, too, was definitely intact and heavily endowed, one might say overendowed.  His balls hung like ripe, furred plums between his haunches, and he barked and sat down, plunking those orbs into the cool grass and giving me a lovely view of his white sheath, thick and baggy, weighted with promise.   The dog panted obliviously, trotting off as I subtly enhanced more and more of the canine genitalia around me.  Female dogs' vaginas thickened and grew more copious, their pussy lips plump and swollen, but there was only one or two female dogs in the park.. just enough to provide pheromones to keep the males interested. It was the males I was interested in today.

An enormous German Shepherd loped into view, his hips lowered and tail wagging, the large, friendly doggy panting a little and stopping to rest, brown and black furred all over, a magnificent dog three feet high at the shoulder, his ballsac fat, like a furry cantelope sticking out and hanging down heavily, his enormous sheath to match, and what's worse, that bag of furred skin that contained his penis was too small for the pink shaft, which peeked permanently from his sheath's gapped opening, a dribble of precum keeping him slick and glossy.  The dog's package was huge, uncomfortably so for the poor shep, perhaps, but as he'd had such a massive organ all his life he was used to it.  He grrffed with effort and lowered his hips, sighing with relief as he rested his heavy load on the grass, as I walked around in front of him and crouched down, smiling.  A friendly scritch behind the ears, and he barked once, playfully, tongue lolling as his sheath immediately began to swell and his needy, pointed, thick red doggycock sloowly, gorgeously slid from his sheath, dangling fat and glistening and jutting between his forelegs.. "Good BOY!" I shivered, feeling my own cock spasm and soak my shorts with cum from the lovely sight.. but there was so much more to see!  I dialed my arousal up but kept myself from spurting again for a few moments at least, my erection throbbing needily and tenting up my cum-slick undies.

I had merely to glance over to get an eyeful of the splayed rear legs of a gorgeous powerfully built husky, tail hiked and wagging as he struggled to lean over and lift his leg hesitantly, trying to scentmark a tree.  His own thickly furred scrotum curved out enormously between his rear legs, easily the size of a volleyball, too big for my hands to cup.  The husky whimpered, trying to brace his lifted leg on the tree, his balls and sheath were too heavy to lift, but instinct drove him to keep trying.  Finally he managed to do it, holding still as a burst of urine splashed musky and yellow against the tree base, drenching it like a hose had been turned on and a puddle spreading and trickling over the ground around him.. He lowered his leg, still pissing like a racehorse, and lifted it again, shifting his balance like a weightlifter, the doggy whimpering with effort and relief.  I had enough time during his routine scentmark to slip around to watch his sheath, the opening's fur soaked and matted with piss, a river gush of urine arcing out to splash noisily on the ground below, the husky peeing for a solid minute or more, lowering and lifting his leg in rest intervals when it got too heavy to hold up any longer.  Finally, lowering his leg for the last time, he waddled off, hind legs splayed around his gorgeously huge ballsac, sheath weakly dribbling piss behind him as he sniffed around for another place to urinate.  Like the other dogs, the husky had no memory of anything else, ever since he was a young pup he'd had to piss almost constantly, his bladder always near bursting, his genitals swollen and heavy and awkward, his leg and haunch muscles corded and powerful, just from the effort of hiking his rear leg 200 times a day, not that it got much easier.  My penis trembled rigidly as the husky investigated a new place to pee, despite finishing less than two minutes ago.  I smiled, a little cruelly perhaps, and increased his urgency.  

The husky was sniffling around the soaked base of a park bench he had drenched just twenty minutes ago, whining with desperation, his pressure building and urine already starting to leak from his sheath tip, but I turned my attention to an even more magnificent animal. .  a Rhodesian Ridgeback, like something out of Klaus' most vivid imaginings, short beige fur highlighting every rippled and bulging muscle, especially the hindquarters.. mouth open and tongue lolling lazily, he merely stood still, rear legs wide and planted on the ground, splayed awkwardly on either side of the humoungous furred watermelon hanging from his undercarriage, behind the sagging plump sheath skin, a fat cylindrical length that could accommodate both my arms with room to spare, were it not for the reddened, glistening penis that took up all the interior space, permanently protuding a little from the too small sheath and jutting out a couple of inches.  The dog was a truly gorgeous animal, noble of bearing and gentle of disposition,  but  every  ounce of his strength was needed to hoist and carry his grotesque ballsac and sheath, his genitals would dwarf most horses', the  lower curve of the tautly skinned balls brushing tantalizingly against the grass even while he was standing.  The ridgeback whurfed and bent his rear legs, taking a few heavy steps, muscles flexing and straining with the effort as he gruffed and trembled, his sheath plumping and thickening from the light brushings of mown grass against the bottom of his balls.  I crouched down alongside the gorgeous animal, feeling  my own little five inch penis straining and throbbing from the musky pheromones this beast was exuding, and I lay down on the damp, cool grass, reaching up and lightly petting the dog's flank...his tail wagging as pleasure surged through his body, and his sheath thickened, the doggy's breathing quickening as he huffed and barked gruffly.  His slanted, bluntly pointed cocktip pushed from his spreading sheathtip, a splurrch of precum hitting the grass and puddling underneath him, as inch after inch of dogcock flesh emerged, the shaft swollen in the middle, ridged and angled at the tip, thick red lines networking across the white flesh, the dog's forelegs shifting and spreading as his cock jutted up between them, his already swelling knot popping free of his sheath..
