Jake hated going shopping on the weekends, but a lack of toilet paper meant a trip to the 'Bullseye' store. People packed in the store on the weekends, and Jake was just another young man who barely stood out from the crowd. He walked his way back from the front of the store to the aisles with paper towels and toilet paper, and along the way, he noticed there was a woman selling free samples of cookies. He saw there wasn't much of a line, but what he 'did' see were many large women. Jake wasn't a huge fan of big huge women. He would never say it aloud though. He tried his best not to be rude.

The woman at the counter, a pink cat girl anthro, would not let Jake get far from her before she spoke up. "Oh! Hey you, I can tell you haven't tried our cookies yet. I bet you would love a sample! They're lemon flavored!"

Jake turned to the woman and sighed. She acted very much like a salesperson, but she was just giving out free samples. He walked up to the counter and glanced at the box. "Big Momma's cookies?" He looked up at the display, and then at the cat girl anthro. The anthro was in no way built like a 'big momma', although the people around her shopping definitely were.

"I know what you're thinking, but trust me when I say these cookies will change your life." The cat girl offered a box.

Jake noticed the box was sealed. He grabbed it and opened it up. He knew the cat girl was not going to let him go until he tried a sample. With one small cookie in his hand, he set the box down on the table.

"No, no." The cat girl insisted. "Take the entire thing!"

Jake raised a brow, but he grabbed the box. "If you're really sure." He ate one of the cookies. The cookie had a dry exterior, although once he bit into it, he tasted a bit of lemon creme inside of it. He wouldn't say it was delicious, but it was a cookie. It was very hard to make a cookie wrong, unless it had raisins in it. As he ate it, he felt a strange rumbling in his stomach. "It really needs milk to go with it." He mumbled. There was something else about the cookie he just couldn't place the flavor. With a small nod to the cat girl, he put the cookies in the seat of his cart before he walked off to grab the one thing he wanted to get.

As Jake walked along, he felt hungry. It only made sense to feel hungrier in a grocery store. He was thankful the cat girl gave him a whole box of those cookies. They weren't fantastic, but they'd work.

Jake made it to the toilet paper section and glanced down the aisles. He noticed there was almost nothing down there still. "Okay, that big problem from before is finished people." He said quietly. He walked down and grabbed the cheap generic toilet paper, the only kind they had left. "Okay, that's all I...umph...needed." He felt slightly different as he set the toilet paper down in the cart. His body felt heavier. He looked down and he saw his stomach push out more than he knew it did before. 'From two cookies huh? I better lay off them.' He thought to himself.

Yet, as Jake walked along, his stomach grumbled again. He looked down at the cookies, and then back at the groceries. He thought maybe he could just help himself to something from the grocery aisles, but his stomach rumbled again. This time, he felt a pain with the rumbling. Jake held onto his stomach slightly and bent backwards as he let out a 'pffrrtt' from his backside. The fart felt long, and it felt as if it came out of two ass cheeks that felt much thicker than his own did. He looked back and confirmed his pants pulled down slightly from how much bigger he was. "Well, crap." He said to himself. He decided to take the cart over to the clothing department while he was at it, but as he walked along, he felt his body sway with fat he didn't know he had.

In addition to light stomach pain, Jake also felt a small headache. The headache wasn't painful enough to do anything over, but it worried him slightly. 'Maybe I'm getting sick.' He was bloated; he had stomach pains, and a slight headache. He wondered if maybe he should head home soon, but his hunger and his clothing problem felt as if it were gradually getting much worse, his headache not so much.

Jake reached into the box in front of him and grabbed another cookie without a second thought. He stuffed it in his mouth, and felt his shirt grow tighter. All of his clothes felt so uncomfortable, as if they might rip at any moment. Even his shoes felt so much tighter on his feet. 'Have to get to somewhere private.' He paused on his way to the clothing department and noticed the pharmacy not far away. He did a fast walk over to the pharmacy as he let out another fart and heard a rip from the seams of his pants. He began to race over to the pharmacy, rushed into the bathroom, and closed the door behind him. He was thankful this pharmacy was just a one-bathroom, but one thing it didn't hide was noise. He realized that as he rushed in, he grabbed the cookies on his way. 'You have got to be kidding me.' He thought.

Jake sat down on the toilet seat, unsure of what he should do. He heard his pants rip again, and he knew he had to take them off, along with his shirt and shoes, which also continued to feel so tight on his body. He pulled off his shoes and stomped on the ground. He looked down to try to look at how much his feet had changed, yet his stomach was in the way. He leaned back, raised his feet, and held onto the seat so he could see them, and his eyes widened.

Jake's feet no longer looked like normal human feet, but roundish feet. His socks could barely hold the feet in until they ripped and revealed his two roundish, but small feet. He had his toes, but his big toe was missing, and the others swollen well beyond the size a normal toe should be. He also noticed his skin looked coarse, and as he pulled down his pants and revealed a very flabby ass, he confirmed it wasn't just his feet, but his legs, as well as even his arms.

"What's happening to me?" He said in a panicked voice. His heart pounded as he looked at his hands, swollen just as much as his feet. His hands were still usable, but they were much thicker. Both his hands and his arms were so thick he couldn't pull off his shirt. Even his pants, while below his bigger exposed flabby ass, proved to be a problem to take off his grown feet. "They look like some kind of elephant's feet." He said to himself. He reached up and felt his face for a growing trunk, and while he did feel something push outwards slightly, it was not that of an elephant's nose.

Jake's stomach rumbled again and he let out another fart. "Oh lordie." He said in a tone higher pitched than his normal voice. He covered his mouth as best as he could, but his big hand was not big enough to hide his growing mouth and nose. He felt his ears pull upwards too as he continued to change. "I'm becoming something that...uh..." He couldn't name the exact anthro he was turning into; he just knew he was becoming something inhuman. Worse yet, it started to feel good to change. His shaft between his legs grew erect and rubbed up against his sagging belly. "Have to resist. Got to find a way out of here."

With his clothes in shambles, Jake knew he was going to have a problem even getting out of the bathroom. He was naked from the stomach down, and his shirt strained at his chest too. He felt more than just fat growing in his breast. He reached up and tried to hold back the tits from growing, but all it did was cause him to touch his nipples and moan from sensitivity. He felt his erect cock spurt a bit of cum onto his belly fat. He swore he weighed at least 300 pounds, if not more.

Jake heard a knock at the door and then a voice spoke. "Is everything okay there? We've had a few people say they've heard strange noises coming from here."

"Everything's fine." His voice cracked into a feminine pitch after the word fine. He grunted and unleashed another fart, much louder than he anticipated. It was then he got an idea. "Can uh...can I get some replacement clothes if I pay for them?"

"If you can tell me your sizes, I can suit you up with something." The male voice replied.

Jake could tell the man didn't want to know any details about 'what' he was doing. He covered his mouth with his entire right hand as he moaned. His cock let loose another spurt of cum. He reached down and felt it, and he could tell his cock felt smaller. His body was larger, but he knew the size of his shaft, and it was definitely smaller than he remembered. 'I don't even know what size I AM.' He thought to himself. There wasn't a full-length mirror in the bathroom to look at himself, but there was one above the sink. "One moment!" His voice didn't crack, but he could tell it sounded different, like an older woman's voice.

Jake pulled himself up from the bathroom toilet and walked over to the mirror. He stared at, not the face of a young man, but the face of a creature that looked almost like a complete anthro hippo. He stepped back and noticed his tits growing above the fat stomach of his. He felt another twinge of pain in his head, and he pulled out his phone from the pants that no longer fit him properly. He got to the screen for facial recognition. "Well, crap." He said aloud as the phone obviously didn't recognize his face. He knew there was a code to bypass it, but he couldn't remember it for the life of him. Numbers felt harder to think about than they should have been.

"Sir? Or uh, ma'am?" The voice said. "Do you have a size?"

"Just bring me the biggest sizes you've got!" Jake said with another crack in his voice that sounded higher. His shirt finally gave way and revealed his two grown tits. His tits measured bigger than DD and rested slightly on his belly. He noticed his nipples looked larger than a normal woman's did, and they were a dark gray, which were just slightly darker than the tone his skin took.

Jake looked back at himself. His small ears, now pulled up into a hippo's own, heard the man walk away. He felt so much bigger, but he no doubt looked like a female. He reached between his legs and had to move his massive fattening thighs aside to feel what was left of his cock. The tip of his shaft dripped a fluid that felt pleasurable to let loose more of, but he realized it was cum, and it was the seed in his testicles draining onto his very thighs. "Fuck...no, no. Go...uhn...go back in." He tried to push his cum in, but he just felt his cock pull back between his legs. "F-fuck, not like thaaaat." He shivered and let out another fart. It felt so 'good' to be so gassy.

Jake looked at the box of cookies he set down on the sink. "T-this is your fault." He grabbed the box with his thick grubby hippo hands, and then his stomach rumbled. "But you don't taste that bad." He reached in and grabbed a handful of cookies. He opened up his much bigger mouth, now more of a hippo's than a human's, and ate the cookies.

He was by now a she, and she was a very fat hippo that couldn't figure out numbers if her life depended on it. She couldn't stop herself from eating more and more cookies, and as she did, her hair grew. She let out another fart, and she felt something leave her with this fart. "Oh...what else is changing about me?" She leaned down and pulled the rest of her pants off her now feminine fat body with a struggle, then leaned back up. Her back popped several times as she leaned back up, and she looked at herself in the mirror quizzically. She knew she was now a hippo anthro, one that needed new clothes she hoped the man was getting, but there was something else.

Jake opened up her gaping maw and ate the entire box of cookies. She tossed the box to the ground, swallowed, and let loose a deep belch. "Oh, I feel a bit tired. Do I look older?" Jake tried to remember how old she was. She held up her fat fingers and tried to count, but she lost track after five, repeatedly, and had to start over multiple times before she gave up.

There was another knock at the door. "Okay ma'am, or sir. I got the largest clothing we have. It is women's clothing, so I hope that will suffice. You can pay for it at the counter when you're able."

Jake walked over to the bathroom door, but her pace was slow. She felt her stomach rumble with hunger and gas. She opened up the door just enough to get the clothes, and then closed the door right after. She slipped the large blue jeans on as well as the red shirt, and the clothing surprisingly fit over her body. She guessed she must have weighed a whopping 500 pounds, if not more, but even if she got on a scale, the numbers would have confused her.

Jake pulled out her wallet from her previous pants, grabbed her phone, and tossed her old clothes into the garbage. She didn't think about collecting them in case she might sure herself, for she wasn't sure if she could. She grew a small tail, and it flickered behind her.

Jake took one more look at herself. The aging didn't seem that obvious, but she guessed she must have been in her late 40s by now, not that she could remember her previous age. Her stomach rumbled again, and she let out another loud belch. She opened up the bathroom door after what felt like an eternity, and ignored the stares as she walked out, now changed into a fat, dumb, hippo MILF. She thought one thing as she left the bathroom.
'I don't know what happened to me. I just know I need to get some more of those cookies.'
