A New Delivery Service
Jimmy picked up the delivery order from the city’s newest, most overpriced, most overrated fusion restaurant, put the delivery bag into his backpack, and stepped out of the door to unlock his bike. He hated menial, brainless, shit jobs like this, ones that got him absolutely no where and ones where the people he dealt with were reliably all motherfuckers. He couldn’t complain too much, though. He got to create his own hours, the constant to-and-from gave him plenty of exercise to maintain his lean figure, he could put in his ear buds and get paid to ride around town listening to music, and there were other perks of the job.
He unwrapped the lock on his bike and put it back in his bag and then pulled out his phone. He clicked back to the delivery app and confirmed that the order had been picked up and waited for the app to load the directions to the drop-off location. His phone chimed as the delivery address was mapped out.
“Bitch, what the fuck??” Jimmy huffed out loud and dropped his jaws at the location. The home he was to deliver the food to was on the literal opposite side of town, up the gradual sloping hill on which the whole town was built, and was apparently a 45 minute biking route. To make matters worse, the app guaranteed a delivery time to its customers within a half-hour window, and docked it from the deliverer’s pay if that window was lapsed.
“Nuh-uh, nope,” Jimmy shook his head and flipped through the app, making his way to the employee support portal. This called for taking advantage of those ‘other perks’ of the job.
He arrived at the ‘Delivery Assistance’ tab of the employee support portal and entered in the details of the delivery. Well, actually he flubbed the details a bit. Exaggerated the delivery distance, over-estimated the weight of the delivery, maybe inflated some more numbers here and there... What the hell, what the company didn’t know wouldn’t hurt them.
He leaned back after hitting submit, watching the spinning wheel on his phone that indicated that his request was being processed. He anxiously tapped his heel against the pavement awaiting the response, when his phone vibrated.
Request granted!
• Enhancement : current stats X 3
• New delivery time estimate : 20 min.
• Duration of enhancement : 1 hour 20 minutes
Jimmy only had time to wheeze out a shocked laugh as he felt his phone send a jolt through his arm. He was no slouch, but three times his current stats?? And for an hour and twenty minutes?? Talk about a lucky fucking break!
His body immediately tensed up as a high moan suddenly escapes his lips, and he could feel himself spreading upwards and outwards. His calves dropped any hint of body fat and tightened, feeling slightly like a leg cramp, but then loosened as thick muscle twisted up the length of his claves and thighs. He felt his ass lift off his seat with a giggle as his cheeks packed on dense meat. It traveled up his back and torso, carving his back, sides, and abs into a sculpted work of art as he felt his pecs begin to bounce. They thudded bigger and bigger as he looked down and giggled with a deeper and deeper moan, taking a handful of each new massive tit in each hand, his breath quickening as he felt his neck widen and thicken while his shoulders rolled forward. As his shoulders pushed outwards to accommodate his still-growing size, they bursted larger with bulging definition. His flexed his already massive arms as he continued playing with his tits and playing with his nipples. His arms had always been his most treasured feature that he kept proudly displayed with a tank top, and now firm muscle snaked down the expanse of his limbs, rising to the surface and bulging into twisting pythons of muscle. His arms crossed as he flexed and felt the new size of his bulging peaks of muscle. He threw his head back in a way-too-loud groan—garnering plenty of stares from pedestrians—at the next sensation. ‘Guess they haven’t fixed the bug yet,’ he thought with a grin as he felt his cock stir to life within his shorts. His typically 4 inch softie bloomed outward, snaking down his thigh and fattening considerably into a soft 12 inch hog, and quickly swelling into an unwieldy, throbbing 18 inch pecker, a considerable increase from his typically 6 inch hard-ons.
Request complete! Proceed to your destination.

He grinned down at his phone and wheezed another small laugh. He should be grateful that they hadn’t fixed that bug, especially considering some of the incredible shit they unfortunately got rid of with software updates. One of the older bugs was what actually turned him onto working for the app. One of his exes was a delivery biker for the app and would often surprise him all the time as a horned-up 9 foot giant hunk—sometimes smaller, sometimes bigger—to fuck him raw and shower him with unbelievable excesses of cum. Sometimes he’d even get big enough that Jimmy could do pull-ups on his rock hard cock hanging stiffly in the air or even use his ex’s cock slit as another hole during their impromptu lovemaking. Enough local prudes complained to the company that they were sick of seeing a bunch of horny muscular giants running around the city, so they eventually ‘fixed’ it, if you can call it ‘fixing.’
Jimmy couldn’t get over the fact that he had so much time allotted with his enhancements. He couldn’t remember the last time he’d gotten such a long time to enjoy his enhancements… Actually, that wasn’t true. The last time was about 2 weeks ago when he finished a delivery way ahead of time and met his boyfriend at the park after. They both loved when the enhancements came through, they were a great means of keeping things hot, impassioned, and adventurous in the relationship. But most times, Jimmy only ever gets a X 1.5 or an X 2 stat enhancement, rarely ever above that. He was a fucking beast now with his X 3 enhancements, and he intended to share his new beast body with others.
He kicked up the kickstand on his bike and pushed off the ground, feeling the wind blow past his face as his new body propelled him on his bike through the air at a speed much higher than he was used to. He grinned as he pedaled up the hill, barely breaking a sweat, and dialed up his friend Pete, a coworker-turned-friend veteran in his early 40s that was stuck in the gig economy cycle like millions of other workers.

He was already a pretty hunky guy—he always joked about thanking the government for giving him his ‘superman body’ but fuck all beyond that—and he was a hell of a lay, too. Jimmy thought maybe he’d be down to party.
He held the button on his earbud and waiting for the ding. “Call Pete,” he said in a deep voice, the confirming ding echoing afterwards and putting through his call. It rang a few times until someone picked up.
“Yyyyello?” Pete answered with his typical goofy greeting for Jimmy.
“How’s it hanging, boss?” Jimmy replied with a grin. He always loved talking to Pete. He would have considered him sort of a father figure if they weren’t such good friends and even better fuck buddies.
“Currently delivering to the west side, buddy. Enjoying a X 1.5 enhancement on top of it, thank you kindly to my benevolent corporate overlords.”
“X 1.5?! Nice, dude, so they got Super-Superman out here delivering food to the masses now?”
“The people gotta eat, Jimmy!”
“And eat they will! I’m sure a lot of them would prefer a taste of your specialty. What was it today, extra long sausage rolls?”
“You know it! All day, every day my guy!” he responded cheerfully as they both laughed. A brief, semi-awkward pause laid over the conversation. “By the sound of your voice, it seems like I’m not the only one here rocking some enhancements.” There was a slight eagerness in his voice.
Jimmy’s heart leapt as he turned the corner to head further up the hill, his cock twitching and drooling out some pre as it rested stiffly against his tree trunk thigh and snaked out of the leg of his shorts. Jimmy looked down at his massive arms and only got harder. “Guilty as charged, dude.”
“How big, bro?” Jimmy could hear the smile in Pete’s voice.
“Oh, you know, just X 3.”
“X 3?! Shit, well then I guess you and I are pretty evenly matched!” He was right! Jimmy smiled and looked down at himself. Fuck, he loved looking down and seeing a porn star body. The developers had to know what they were doing when they made this feature. And come to think of it, he was basically the same size as Pete now, except almost double the package size, thanks to the system bug.
“I’d say you’re right! Buuut,” Jimmy bit his lip feeling a grin stretch across his face. “I think I have, well… about 3 times more the package you do.”
“Woof, shit… I guess I can deduce that you’re not talking about your delivery order! You’re making my mouth water, stud,” Jimmy could hear the grin in his voice as he painted on his bike. “Making my cock water a bit too, if you know what I mean!”
“I think I do, Pete. I think I do.” Jimmy kept pedaling up the hill while a silence hung over the line for a second. Jimmy could feel his bulging size press against itself as he leaned over to pedal harder. “So… Meet up at the park bathroom after our delivery runs?”
“Fuuuck yes, man! Haha, I was beginning to worry you’d never offer!” Pete chuckled to himself for a second. “Now this is gay culture: two alpha studs swapping spit and jizz in a public bathroom.”
“It’s what our forefathers and foremothers would’ve wanted,” Jimmy quipped back, suddenly realizing something. “OOOOHH I think Richie is working today. Wanna make it a party?”
“Abso-fuckin’-lutely, the more the merrier!”
“Awesome. Either way, I’ll see you in like 10, good?”
“Good. Keep it stiff for me, stud.”
Jimmy smiled and hung up. That would be no problem; he’d been fully cocked since he heard Pete’s voice, and his unnaturally large cock head was poking out of his shorts by now, leaking sticky pre onto his thigh as he pedaled. He just hoped Richie could join in on the fun.
Jimmy knew that Richie only worked a few days out of the week, but took only the biggest jobs when he did. He loved the extra money, sure, but he loved the enhancements more. Jimmy could remember more than a few occasions that he ran into Richie while he was looking like some body builder fetishist’s giant, sweaty, throbbing wet dream. It was comically different from what Richie was like outside of work. If you saw him on his work days versus his short, twiggy appearance and demeanor on his off days, you’d think they weren’t even related.
He tapped the button on his earpiece again, “Call Richie,” and listened to the ringtone. After a few rings, the line answered.
“YOOOOOOOO,” Jimmy heard a thundering, impossibly deep voice answer.
Jimmy’s grin widened. They’d need a bigger bathroom.

Gwen could smell the cigarette smoke wafting from one of the apartment windows as she jogged along the street. She always hated this part of the walk because there was usually someone sitting outside on their apartment balcony and she felt "watched." Gwen was in her mid-twenties, just out of college, but single. She worked downtown at a bank and wore fashionable work clothes, but today on her run she wore simple athletic gear. She had an attractive body, lean and fit, and she hoped to keep it that way. It was on this street in particular that she could feel people "watch" her as she ran and it was unsettling. Today, her cell-phone rang, which threw off her running music, so she stopped to check her phone and get the music going again.
When she stopped, she could smell the cigarette smoke even stronger and felt eyes watching her from above. She glanced up and saw a thirty-something guy leaning over the railing and looking at her. She broke eye contact and paced a few steps, but still felt watched. He heard the man clear his throat and spit.
"Lookin' fine, girl! Don' stop now! Keep on'a runnin' " said the guy with a laugh.
She ignored him and tried to get her phone to start her running mix again. While she fussed with her phone, her water bottle slipped and fell onto the sidewalk. She could feel the man's pervert eyes watching her as she reached down to pick it up.
The man let out a loud whistle, "Nice ass! Come by later and I'll help you keep it in shape!"
She had been cat-called before, but this guy was starting to cross a line. Earlier that week, a friend had told her to download an app called "Men Are Dogs." It was supposedly some way to report incidents of guys acting like jerks or "dogs" so other girls could look them up and feel safer. Her friend had thought it was funny to see what kind of guys made it into the database, but Gwen never thought she would actually have to use it.
In a second, she grabbed her phone, opened up the app, and turned to the guy in the balcony.
"You want a picture! I'll give you more than a picture," he shouted as he grabbed his crotch and gestured vulgarly.
This was the first time she actually had a chance to look at this creep of a guy. He was wearing torn jeans and a white sleeveless t-shirt. He was a broad shouldered guy with a big build, but had a beer gut and flabby arms. He looked pretty strong, but not really in shape. His light blonde hair was cropped tight, almost shaved and he had a tattoo on his shoulder. He threw his cigarette in the bushes and licked his lips and thrust towards her again, laughing.
Her phone snapped a picture and within a few seconds the message read "Strike Three," which must have meant this guy had been reported by two other users. The next screen said "Teach this dog a lesson? Yes or No." She wasn't sure what this actually meant, but the guy was being a real dickhead, so she chose "yes."
The screen buffered with the message "Dog in Training," which had a picture of a muscular man wearing a dog collar and panting stupidly. She looked up and saw the man on the balcony look like he was choking and fall to his knees. She ran closer, hoping it wasn't all some stupid act. He was pawing at something at his neck, which Gwen realized was a leather collar. He made a few choking sounds and then looked at her and stuck his tongue out stupidly. Suddenly, his body started to shape shift into a compact, muscular dog. She saw a leash attached to the collar and the dog pleaded softly and looked up at her.
Her phone vibrated and she read the message, "Say hello to Kurt." She grabbed the leash, not sure what do with this man that she had watched transform into a dog. She was happy that he had stopped harassing her, but thought this was maybe an extreme reaction. The phone continued by asking "Bring Home or Bring to Pound?" She chose "bring home," but just wanted to get out of there before anyone one noticed. Kurt trotted in front on his leash while she finished her run.
As soon as she got home, she texted Amanda, the friend that had shown her the phone app. "No way!" was Amanda's reaction, "send a pic." Gwen snapped a picture of Kurt and sent it. "I'm coming over," Amanda replied.
--
"Oh my god!" Amanda squealed when Gwen explained what had happened. "He's so cute," she said as she pet Kurt on the back while he panted and barked.
"Well, he was saying all this stupid shit, and I just thought I'd take a picture and leave ... but it turned him into this dog ... and now I don't know how to turn him back!" Gwen stammered. "I don't want a dog!"
"But Gwen, look at him," Amanda said as she continued to pet Kurt's head.
"I don't want a dog! Especially one that was some sicko guy from the street!"
Gwen's phone suddenly vibrated again and she pulled up the app. She saw a picture of Kurt before he was a dog and the words "Teach your dog a new trick? Yes or No."
"What should I do," Gwen said in frustration. Amanda grabbed the phone and chose "yes." Kurt whimpered a little and then rolled over on his back. In a few minutes, his dog body had transformed back into the original Kurt, but he stayed motionless on the floor. Thankfully, his clothes had reappeared so they didn't have to see a nude guy "appear" on the living room floor.
"Woah," said Amanda. "So you're not kidding!"
"Of course not!" shouted Gwen. "This is him!"
"Give a command," prompted the phone and Amanda selected "Roll over." Kurt obediently rolled onto his belly. "Stand up," and Kurt stood up. "Try your own," read the phone. "Take off your shirt and flex," shouted Amanda. "Amanda! Stop it!" Gwen tried to say, but Kurt obeyed by taking off his white t-shirt and flexed his muscles. While Amanda gawked about controlling Kurt, Gwen saw her pile of unfolded laundry and had an idea for a command. "Kurt, fold my laundry." Dutifully, he walked over and started folding clothes. "Nice one," Amanda replied. "You've got a live-in butler!"
While Kurt folded clothes, the phone popped up another message. "See grooming options." Amanda and Gwen fiddled with the sliding bars, one for muscle, hair, height, etc., but they couldn't decide so they selected "Suggested grooming." They watched Kurt transform again, this time into a muscular young man with ripped abs, a tight ass with a thin waist. Long legs and arms with lean muscle, broad shoulders and sucked in stomach. His hairy belly and back were smooth, like he was properly groomed. Even his smile and eyes looked more attractive.
"Good lord!" said Amanda. "Take off your pants, Kurt!" and he obeyed. "No, like in a strip show!" Kurt walked over to her and started grinding while slowly unbuttoning his jeans. He had on a pair of tight underwear which showed his massive cock. But Gwen choose, "Kennel" on the app and Kurt stopped, curled up on the living room floor and within a minute was back to dog form.
"Oh come on!" said Amanda. "It was just getting fun."
"It's late, Amanda," said Gwen. "And I have to work. Plus, I just want to go to bed and figure out what to do about this in the morning."
"Fine," said Amanda as she headed towards the door. "But invite me over so I can play with your 'dog' once and awhile."
"Haha," replied Gwen drolly.
--
At 6:00 AM, Gwen heard scratching at her door. "What the?" she said as she staggered. She opened the door and saw Kurt scratching his paws to get her attention.
"Do you have to go outside," she asked and she knew the answer was yes. She grabbed the leash and walked him outside to take a piss on the lawn. She changed into her running gear and thought maybe she could take Kurt running with her.
After the run she started getting ready for work and took a quick shower. She stepped out wearing only her towel and screamed when she saw a man standing in the kitchen. But she realized it was only Kurt, who was busy cooking breakfast. He was wearing only his underwear and was the muscular version of himself from last night.
"What are you doing?" asked Gwen, as if talking to a pet. She was startled when he answered, "Making breakfast for you."
"Wait, you can talk?"
"Of course I can talk!"
The whole time since taking Kurt home, she hadn't heard him speak a word. Also, she noticed that even though she was only wrapped in a towel, Kurt was making perfect eye contact with her, not looking at her body or barely covered breasts, just right into her eyes. She felt a little sad for him, but also a sort of "puppy love" at how cute he was making breakfast for her. She finished changing, ate breakfast, and headed towards the door.
"Kurt, I'll be back around 5. Just don't mess anything them and keep clean, okay. Make yourself lunch."
"Have a good day, Gwen," Kurt answered with excitement as she closed and locked the door.
--
When Gwen opened the door to her house she didn't know what to expect. Would Kurt still be there? Would he be a dog-dog or a man-dog? Would he have run away? Would she keep him? What about Kurt's friends and family?
"Kurt, I'm home," Gwen called out. She heard the shower turn off and Kurt ran towards her, this time completely naked.
"Hi Gwen!" he said enthusiastically. She saw that Kurt's massive cock was swaying, half-erect. "Wanna get some exercise?" said Gwen.
"Yes, of course!" answered Kurt, who loved running. He ran to get the leash and held it out to her.
"Not that type of exercise," said Gwen as she led him towards the bedroom. "You're going to fuck me until I tell you to stop, okay!"
"Okay," he said, hopping up on the bed.
"And you're not going to talk until I tell you," she said. Kurt nodded.
"And go slow. You need to be more man and less dog right now," she added as she dropped her work skirt to the ground and pulled off her blouse.
After there love-making -- the best Gwen had ever had! -- Gwen had a notification on her phone. "Training Complete. All Men Are Dogs!"
She looked over at the muscular man-dog lying in bed next to her, looked at his smooth chest, thin waist, and tight ass, and put down the phone, fully determined to adopt this stray and keep him well-trained.
