The Test house was empty for the most part. Everyone was gone for their own separate reasons and the only inhabitant within the four walls was the talking family dog, Dukey. Having the house all to himself for the entire morning was an exciting thing at first. But he quickly grew bored after flipping through many channels and attempting to read some books that seemed boring to him for some reason.

Though it wasn't on the same level as Johnny, the canine did have a mischievous streak within him. And the streak encouraged him to go into the secret lab. Of course he was usually barred access unless it was to act as some kind of test dummy for their experiments. Susan and Mary wouldn't be happy with him meddling with their stuff but that would only be the case if they found out...

He spent some time testing out some inventions, getting some cool results out of some. But others didn't seem to do anything. Maybe it was because he didn't know how to actually use them. Again, that boredom started to set within him as he cycled through the various gadgets and gizmos. Any interest or excitement he gained from them was short lived, leading him to seek out something new.

Dukey surveyed the large table that was against the back wall. That's where the unfinished projects were. He knew it wasn't a good idea but he couldn't help but approach and mess with a few things. Unfortunately everything was in an unusable state, all missing parts that would make them work. That was a shame because some of the notes placed by the projects were promising and even exciting. One thing did stand out among the others and it was an ordinary pack of gum. Dukey helped himself to a piece, figuring that there was at least one thing on the table to entertain him.

When the taste met his tongue his body jerked. It was a horrible taste that clung to his taste buds. His throat suddenly became dry, as if the moisture was being drained away. And after about a minute, it felt as if his throat was closing! Working on desperation, Duke spit out the gum and searched for something to drink. His eyes fell on a glass cup filled with something. It was on a regular table so Dukey assumed it was an ordinary beverage, not being in a position to be picky anyways.

He dashed to the glass and began to drink from it, gulping down the sweet tasting fluid. That intense dryness in his throat was relieved almost right away and he let out a relieved sigh, placing the empty cup back down. Coughing and rubbing his throat, the mutt felt normal again. When asking himself what just happened, Dukey figured that it was another invention. It was rather dangerous to make something like that in the shape of regular gum but then again he wasn't meant to be snooping around in their stuff, let alone in things that were still in development.

With the crisis averted, Dukey figured he had enough excitement. It was time to leave the lab and do something else. Perhaps he could jerk himself off one or two times, letting the loads shoot out and mark his pelt...

Dukey shook his head. Why did he suddenly have that idea? Usually he used the quiet time to catch up on reading or his favorite shows. He could take care of himself in the late hours of the night when everyone else was asleep. Despite that reasoning, the desire still clung to him. It remained in the back of his mind and was becoming more prominent and harder to ignore. After a full minute his body was pulsing with a sense of desire that he didn't usually feel.

"W-what's going on?" Dukey asked himself, coming to his senses for a moment. Instantly he suspected something in the lab to be the cause. He should have known better! There was always trouble involved with those inventions. When asking himself what the cause could be his eyes fell on the pack of gum he had taken a piece from. Realization came over him. Whatever that gum was meant to do, it was instead making him incredibly horny. Rather than a sense of fear he instead felt his mind fogging up with thoughts and desires of lust.

There was nothing for it. He had to jerk off! The sense of need was becoming too much. All he wanted to do was grip and stroke until he was shooting...

"Shut up!" Dukey shouted, yelling at his own inner voice. He raced out of the lab, hoping that getting out of there would help. Upon reaching the kitchen he took some drinks from his bowel, feeling the cool water run down his already soothed throat. Just as Dukey began to feel normal a grunt was forced out of him, coming from the sudden pang in his sheath. A sudden tingling feeling flared up down there and it couldn't be ignored.

"You're better than this..." Dukey muttered to himself. Despite the sense of need taking hold within him, the mutt reminded himself of his standards. He wasn't the kind to just start pawing off just anywhere. If he was going to do this it was going to be done somewhere private...

That was easier said than done. When moving his balls swung a bit that the light tingling became a burst of pleasure that scorched through the rest of his body. Dukey moaned out and his body stiffened. Lust hazed his mind again and he realized that he had only taken a single step. His sack felt so sensitive now. Not only that, he could also feel its weight. It was suddenly so heavy with seed that his mind was begging him to expel.

Dukey knew he had to do something. There was no telling what would happen if he let this continue. Would he go crazy from the feelings or would it become permanent. Every step taken leaving him a shuddering and moaning mess? Finally giving in to it all, Dukey pushed himself to take step after step. Despite it all he kept to his standards and found somewhere that he could do this. Moans and whimpers left him with every step taken. He opened the backdoor and raced to the doghouse, slipping his brown -furred body inside. Not only was it a private spot, but he could also make a mess without worrying about consequences.

He finally sat back, looking down at his sheath. For a moment it seemed to be a bit bigger than usual. This couldn't be pondered as another burst of feeling was forced through Dukey, getting his cock to instant hardness. His red knotted flesh slipped right out of the sheath, soon standing at full attention. It was already leaking as well, oozing a thick string of precum that slid down to his balls.

Finally giving in, Dukey had his paw between his hindlegs. His digits were wrapped around and pumped up and down. He started out fast, needing relief badly. Precum was shooting from his tip, making his paw wet, warm, and slick. A good amount of it was spilling on the soft grass, coating the blades underneath him. The mutt moaned out as he jerked himself rapidly, gripping and squeezing length for added pleasure. His cock responded with harder throbs before spitting out more clear ropes.

Having stroked himself so furiously, Dukey was groaning and clenching his teeth from the increase of feeling. His cock felt more sensitive than usual, responding to every touch, jerk, and squeeze given to it. His paw was sticky and the fur was matted from all the precum that had spilled out of him. It felt so good that he didn't notice how much it really was. The mess he already made was enough for at least three dogs pent up dogs and more was spilling out. His focus was instead on his approaching climax, sliding his paw as fast as he could manage.

Feeling his balls churning, Dukey reached his other paw to give them some attention as well. But upon touching them all of his actions paused. He wasn't sure if he actually touched himself at first. But when doing it again the pleasure in his sack was unmistakable. Yes, the canine was touching his balls but...

As far as canines were concerned, Dukey was above average when it came to cock length relative to the rest of his body. But his balls were pretty ordinary, swinging simply between his hindlegs. At least that's how they usually were. He hadn't noticed thanks to his legs being spread but the feeling and looking down there was no denying it...

His balls were bigger! Both of the furry orbs were more than double their original size and when looking even closer he could see them expanding while still churning. Of course he was ready to panic but he couldn't help but keep rubbing his sack, feeling them expand against his touch. His lust-hazed mind could hardly grasp it and yet they were still plumping up. Not only were the balls themselves getting bigger, but so was the skin and fur that surrounded them, stretching out to fit over them.

Dukey watched in amazement as the size of them was becoming more and more. Rubbing them felt so good and he felt the pleasure rising even without touching his cock anymore. His other paw joined in on caressing his balls. The both of them were about the size of grapefruits, pulsating from his rubbing and light squeezes. Precum was flowing out in thicker ropes, making a bigger mess out of the grass under him. His loins were throbbing and he threw his head back from his climax finally arriving.

Dukey let out a soundless moan as his cock throbbed hard. He was sure that he reached his climax but pressurized jets of precum sprayed from the pointed tip, splattering onto his own body. His pelt was getting wet and weighed down with the large amounts of hot fluid that all rushed out at once. A sense of bliss came over him, almost as if he was actually releasing cum.

He still needed more. Without thinking about it, he grabbed his still spraying shaft and continued to jerk it fast and hard. Panting hard, the mutt also rubbed his swollen balls. They were the size of melons now and he could feel their weight. Though so much precum had been ejected, they still felt full.

They were churning again and this time his sensitive ears could hear the liquid sloshing around. His cock was throbbing as well, reaching that point of no return again. Pumping his knotted length up and down with full speed he finally howled from the almighty bliss and relief that overcame him. The precum had unleashed in the form of thick gushes but his actual climax was expressed through a torrent of thick, hot spunk. It was rushing out of him like a firefighter's hose, reaching up to and splattering against the ceiling before oozing down in thick globs like rain.

Things kept going from there. Another wash of his climax flew from his cocktip, overwhelming Dukey from the feeling. He could only squirm and moan while painting himself and the doghouse's interior in layer after layer of his balls' contents. It happened again, and again, and again. When the last jet of his cum was released, Dukey was practically bathing in his own essence.

Dukey's tongue lolled as he finally felt a sense of relief. His doghouse was no doubt ruined from the inside but the outside was a mess as well. The force had pushed the spunk through the boards and the structure was literally oozing from its sides and the roof. Of course his own body was slathered in pearly seed, weighing down his shaggy brown pelt.

"Ugh... How am I gonna clean up this mess?" Dukey groaned. He unconsciously brought his paw up to his mouth, licking up his own cream before all but sucking it off. Moans of delight slipped from his muzzle, being fully heard when his digits popped free.

He thought that was the end of it, but arousal took hold of him again. His cock was still hard and his balls were still plump with stored fluids. At least the expansion had stopped, but his balls were huge now. He could use them as a personal cushion if he wanted. How long would this last? Would he have to completely drain them? Or just wait for the effects to wear off? In the back of his mind, he considered staying like this, having huge balls that were just shorts of dragging along the ground. Being the envy of any other dog around. Of course he would have to explain how he got like this but that was a problem for later.

For now, Dukey picked up where he left off. His cock was sloppy and it was all too easy to jerk himself off with both paws. He basked in the wet weighted blanket of warmth and his nose was filled with the scent of his own marking. More precum was gushing out, oozing onto his already slathered body. His body suddenly felt hot between his hindlegs. Something was going on. His balls weren't the issue this time.

Dukey didn't notice right away but his cock was starting to pump up as well. The growth was faster than his balls, maybe before it was focused on one body part rather than two. Whatever the reason, his shaft was expanding along with his sheath, increasing in both length and girth. His paws spread out further from the flesh getting wider and the throbs were harder against his pads. Panting hard, Dukey continued to stroke himself, having reached nearly three feet when it finally stopped. His cock was pulsing and every gush of precum was spurt directly against the roof, raining down with heavy rainstorm-like force. This was all so sudden and strange but Dukey didn't care.

For some reason he loved this. The pleasure was incredible, making his body shake with even the simplest of strokes. Precum was spilling out every second, being unloaded with every throb. He pulled his knotted hyper dick close to himself. Wrapping his paws and arms around he hugged and stroked along with all the effort still within him. Joining in was his tongue, licking and swiping against the shaft. He took in mouthfuls of his own cum, letting the musky taste overtake his taste buds. He moaned and gasped, basking in the absolute bliss of pleasuring himself in this state. He picked up the pace and growled as he felt himself getting close again, listening to the fleshy throbs and gurgling of his balls getting ready to unload its contents again.

His orgasm struck again, being stronger than anything else ever experienced. His body could only writhe in response to the intense feeling of his cock swelling and spraying its loads within the doghouse, completely ruining it both inside and out. He continued pumping and licking as the sludge of his own spunk came cascading down onto himself, leaving him to bathe in the stuff. A rush of his cum had oozed out beyond the doghouse, forming a thick river of the hot and gooey stuff.

Dukey finally felt relief and was glad to see that his cock was retreating into the sheath. But it remained fat and swollen just like his balls. He should have been concerned about his loins staying in such a state but instead the canine was overcome by all the sensations, just laying and panting hard in the complete and total mess that enveloped him from all sides and even above, still dripping down on his body. He figured he could remain like this for a while. After all, he was technically testing out the gum's effects, therefore helping. That's what Dukey told himself as he closed his eyes and drifted off to sleep...
