A shrill bell cut through the dry air of the high school classroom, causing the students inside to rise and gather their bags as Mr. Kent shouted over the clamor.

"Remember the homework due tomorrow! No extensions, you've had all summer," he said as a dozen teens ran past him and out the door. Mr. Kent's chemistry class was the hardest senior course in the school, but the kids never understood until they failed this first assignment.

He sighed as he picked up his briefcase and stepped toward the door.

"Is it too late to get help?" a voice rang out from the back of the classroom, where one student had stayed to collect his belongings. It was Matthew's last class for the day, and it marked the end of a hellish first day in a new school. The boy had just moved to San Francisco, and he didn't want to be seen walking home alone.

"From me? Yes. See you tomorrow," Mr. Kent said curtly before walking into the hallway. Matthew turned red, and he stuffed the rest of his textbooks into his bag. I guess there's no scoring points with this teacher, he thought to himself.

Matthew bent down to pick up a pencil off the ground. All he had to do was keep his head down, and the school year would be fine. The internet could probably solve most of these equations anyways.

"I heard you needed help!" a high-pitched voice said from the front of the room.

Matthew turned around and jumped back. The owner of the voice, a short, Japanese girl wearing a frilly pink dress, looked excitedly at him. She barely grazed five feet.

"The homework is pretty easy. All you need to do is mix a few compounds from the class cabinet and record the reactions. Easy A if you get the right combinations," she said. She seemed to bounce with excitement, almost tap-dancing as she shifted her weight from left to right.

"I'm sorry, who are you?" Matthew didn't recognize her from class, though Asians usually didn't catch his eye. The raven-haired girl could've been in all of his classes today and he wouldn't know.

"Oh, I'm Kallie!" she beamed while walking closer. Weren't these girls supposed to be quiet and shy? Matthew thought to himself. They were also supposed to be smart, which could come in handy for the assignment due tomorrow.

Matthew put his bag down on the desk slowly, realizing that Kallie could help fix the first impression he gave Mr. Kent earlier. An A+ would surely impress the grumpy teacher.

"It'll only take a few minutes, really!" Kallie continued in that enthusiastic voice, crossing the classroom to open the cabinets that stored the chemicals. As the thin girl reached the shelves to grab a box of shimmering vials, Matthew saw the lace of her dress drift up slightly, exposing her creamy, pale skin and a sliver of white underwear.

Blood rushed to his cheeks and his dick. Thank God the slight tent in his khakis wasn't bad enough to where she could see, since she was already walking towards him.

"So, where are you from?" Kallie said with a twinkle in her eye. "I sure haven't seen you before. And I definitely would've remembered a guy like you." She put the box of vials down on the desk and looked Matthew in the eye. She was almost a foot shorter than him. She crossed her arms and waited for an answer.

For some reason, the way Kallie was looking at Matthew with a slight smirk made him feel like she knew that he'd seen her panties. She raised an eyebrow and tilted her head playfully. He didn't notice it before, but she smelled of strawberries and cream.

"Wyoming," he said. He didn't want to say he was from a town that had more chickens than people. And more churches than convenience stores. This was San Francisco, and it was a hell-of-a-lot more diverse than what he was used to. His parents brought home Thai food when they'd moved in last week, and he'd choked at the table.

"Not many Asians there, right?" Kallie chuckled as she mixed the contents of three vials together in a beaker. "Bet this was a shock."

Matthew didn't really know what to say. He shrugged and nodded. I guess it was, he thought. Asians weren't really his thing, but he'd noticed the bubble tea stores and mixed-race couples around town. Still though, there were plenty of white chicks. He smiled a bit as he thought about a couple of blonde cheerleaders he saw earlier at the cafeteria.

Kallie's eyes narrowed slightly, as if she could read his mind. Her small hands shook the beaker a little quicker. She wrapped her two fists around the cylinder and swished for a few seconds. Once the liquids were mixed enough to satisfy her, she uncorked it and smiled.

"Here, sniff it! If it smells like flowers, we've got the first problem down," she said, grinning as she offered the beaker to Matthew. A couple K-pop themed bracelets jingled on her wrist as he leaned in and took a deep breath.

Woah. The smell of cherry blossoms hit him strongly. He leaned back, but found himself suddenly weak in the knees. Matthew grabbed the table to steady himself.

"Ope! Did I make it too strong?" Kallie asked. Her voice seemed far away. It didn't matter though, because he crumpled to the ground, narrowly missing the chair. The last thing he saw before the world went dark was Kallie's face, grinning over him excitedly.

When Matthew woke up, he couldn't move. He was on his back and strapped to a lab table with black ribbons. He panicked and started to struggle against them. Then the smell of strawberries and cream hit him.

"Hey there! Glad to see that you're awake now!" Kallie's familiar voice rang out from his left. Spooked, he shifted to his right. "It's always fun to see the changes this way."

Matthew was confused. His stomach felt off, like he was nauseous. His head hurt. Kallie leaned over the table until her face was right above his. Her long, black hair tickled his cheeks. He didn't notice it before, but Kallie's eyeliner was in the shape of a cat-eye, accentuating her monolids.

"What the hell?" he groaned. He knew he shouldn't have trusted her. The ribbons that kept him tied down wouldn't budge, no matter how hard he pulled.

"I thought senior year would be lonely. My ex moved away this summer," Kallie said as she put her hand on his stomach gently. Matthew's nausea was getting worse. "But the second I saw you, I knew I could make you mine."

"I don't like Asian girls," Matthew said, his head throbbing as the words left his mouth. Before, he thought they were weird. Now, they were psychotic.

"You do now," she said. "Look." Kallie's hand slid down to his khakis, where his dick was slowly filling out the erection that started when he peeked at her panties. He groaned as she slid her hand under his pants and rubbed slowly.

Matthew couldn't deny that it felt good to have Kallie's hands on him. It'd been a while, and his body knew it. Kallie had a lot to work with. He was on the girthier side and not lacking in length. His balls were sensitive, and she could feel their warmth as she cupped them. She had a soft touch as she moved back and forth between his balls and his cock, coaxing until he was fully hard.

Once she realized Matthew was there, she chuckled and said, "There we go. Time for the fun to start."

She pulled away, lifting his t-shirt up as she went. Matthew sighed as he felt a weird sensation start to spread from his belly. He strained against his binds and looked down, shocked at what he saw.

His stomach was slowly expanding. Matthew wasn't the skinniest guy, but he was proud of the lean build that years of farm-life had given him. Now, he was watching his light abs disappear under a layer of fat. The warmth from that fat radiated outwards until he felt tingly from head to toe.

"What's happening to me?" Matthew said. "What was th-"

He stopped talking when he realized his voice had changed. He sounded nasally, like his words were caught in his sinuses. Kallie smirked. He didn't realize that he couldn't see her as clearly as before. She leaned in closer to his face again, and then she came into his vision. Did the chemicals screw with his eyes?

"It's easier if you just go along with it. Enjoy the process, senpai," Kallie said in a cutesy voice. She grazed her hand across his cheeks, which were starting to feel a little bloated, like a chipmunk's. She leaned in even closer, closed her eyes and kissed him lightly.

He almost turned away in time, but once her lips hit his, he froze. Something about her strawberry-smell lingered in his brain, warping itself with the cherry blossom scent from earlier.

セクシー. A voice in his head spoke Japanese to him. Sek...ushi? He softly repeated the syllables as Kallie pulled away, not realizing that he was speaking aloud.

"Oo, Japanese!" she squealed, jumping up and down. Damn, that was cute. Wait, what? Another thought floated into his mind as he looked at the skinny girl celebrating. Her pink dress stood out before, but he hadn't noticed her cute pigtails or the little pastel clips in her hair.

God I want to cum on her face. He startled himself with that. Usually, he'd jerk off to Sabrina Carpenter or Taylor Swift. Now, something about Kallie's dark, slanted eyes sparkling with anticipation stood out to him.

He shifted to the right as the bloated feeling intensified, and gasped as he looked down to his stomach. The fat on was now accumulating faster, spreading to his thighs and chest. He might've been a slimmer 155 pounds before, but Matthew was easily pushing 180 at this point.

The rolls on his stomach started to wrap around his sides, connecting with a bulk of fat that he didn't realize was putting inches in between his belly button and the table. He was slowly moving up as his ass grew down and outwards in two flabby globes. A pool of sweat started to collect under him. His throat pulsed thrice.

"What the fuck is happening to me," Matthew said, cringing again at that nasally voice. He sounded like a geek. His arms started to inflate, pulling at the ribbons that tied him down. His biceps shrank and were replaced by pockets of fat that guaranteed bingo wings.

His arms thickened overall, and his fists became hammy as his fingers turned into sausages. Dark hairs started to grow on his forearms, traveling upwards toward his shoulders and running down his fattened torso, speckling what looked like the start of man-boobs.

"Don't worry mister," Kallie said, her pigtails bouncing as she nodded enthusiastically. "Your waifu will take really, really good care of you."

She moved down the table back to his khakis. Her hands quickly dove into his shorts this time, and the second she touched his erection again, he gasped.

Her soft hands felt so good. She used her palms to slick pre-cum onto his throbbing dick, slowly moving both fists down the warm staff. Matthew didn't realize how much pre-cum he'd been producing. He groaned as she moved up and down his length with firm hands.

"My waifu," Matthew said softly, the words unintentionally slipping out as he basked in the pleasure that was radiating from his groin. He was light-headed. What time was it again? And why was the world dizzying?

He glanced at Kallie standing at the side of the table. She looked so kawaii when she was this focused, he thought to himself. Her breasts were maybe a C-cup, and they sat beautifully on her chest, swaying softly as she put her whole body into the handjob.

"Let's get these off of you, my sweet," Kallie said as she pulled off his khakis and boxers, exposing his throbbing dick. Matthew took a sharp breath as the cold table connected with his fattened butt and thighs. His warm sweat condensated quickly and created a moist, sticky surface under him.

His dick stood at full mast, dripping pre-cum as he panted painfully, waiting for Kallie to stroke it again and relieve the ache. Matthew was distracted from the fact that he hadn't stopped growing this entire time. His figure had filled out considerably while she was touching him.

Forget chub-rub. At this point, his legs were permanently wedged together. He now had wide hips that would sway when walking. His thighs had fat pockets that would fold over his knees, and his calves thickened into trunks, connecting with puffy ankles and widened feet that were stuffed into his shoes.

Matthew hadn't noticed that his man-boobs reached an A-cup or that his shirt had ridden up even further to make a crop-top out of what was once a loose T-shirt. His reddened cheeks, which felt puffy earlier, jiggled as they connected with fat that expanded his widened neck. In between them sat a double chin that almost had a third pushing out from underneath.

Matthew had to be 230 pounds by now. He whimpered when he noticed that Kallie hadn't continued stroking him after pulling off his clothes. Throwing his head back in frustration, he felt his cheeks jiggle before settling into a reddened, sweaty state.

"Not yet," Kallie chuckled as she traced the happy trail leading down from his belly button, causing him to jerk his hips forward in hopes of presenting her a ready and waiting staff.

Matthew groaned, moving further and pulling the binds that strapped him down. His balls, which had started swelling at the beginning of the process, had topped out at double their original size, and hung heavy and thick on his pale thighs.

Bushy brown curls encroached on the base of his dick, and sweat drops created a permanent musk that would linger past this transformation. The old Matthew trimmed, but the new Matthew let it grow wild.

"Please," Matthew cried in exasperation, once again jerking his hips sharply upward. His legs, losing muscle quickly, dropped down on the table from exhaustion. They made a thud as the fat bounced. It was as if he'd dropped bags of flour on the floor.

He groaned as his breathing became heavy under the fat collecting on his chest, smacking his lips as the chemicals locked a heavy lisp in his speech. His man-boobs sagged left and right toward the ground, pushed to the side by his heaving, hairy belly.

Matthew's head throbbed again as his memories started to cut in and out. The websites featuring thick and blonde women he watched when he was younger turned into hentai and Japanese women making ahegao faces. He remembered his first kiss not being Emily in the 6th grade, but rather a paper cut-out of a J-pop star he'd printed in the school library. Every birthday party and Halloween costume he had since elementary school was anime-themed.

Despite the fact that no Asians lived in his town in Wyoming, his parents tried their best to support their son's interest in the region. They'd saved up enough to send him abroad for a semester in high school after he proved to them that he had become fluent in Japanese, as if the massive collection of anime figurines and manga he built over the years didn't display dedication.

Matthew's mom being transferred to the San Francisco office of the green-agriculture company she worked for was the best thing that's ever happened to him. How else would he have met the most perfect Japanese girl, Kallie, who happened to live next door?

"Baby?" Kallie said as she reached for his dick. He gasped as her small hands wrapped around it and slowly began stroking up and down. She climbed onto the table, and swung one of her legs over him with slight difficulty, never letting go of him while she did.

His memories flickered as she stared down at him with her dark eyes. Wait, they were doing homework a few minutes ago. What was this girl doing on top of him? He struggled to prop himself up on his elbows. His round cheeks swaddled his face, puffing out and fighting for room.

Matthew panicked as he looked at his ham-hocked arms that sported dark hairs. The sweat under his back rolls felt moist. The khakis that wrapped around his thick ankles barely looked like they could be pulled up across his knees.

"Please," he said, cringing again at the tone coming from his mouth. It was more of a strained whisper at this point.

Smirking, Kallie slyly reached her hand under her frilly pink dress and pushed aside the white lace panties he'd peeped at earlier. Steadying herself with one hand on his dick and the other on his massive belly, she plunged onto him with no warning, gasping as his thick member pushed at her walls.

Her slick pussy felt tight and warm as she slid over him. Matthew had never felt this good before. He fought against the rings of fat on his chin to look down at her with a dazed look on his face. She met his eyes and placed both of her hands on his belly lightly.

Kallie looked beautiful, like an Oriental goddess from a period drama. Her pink lips parted to release a high-pitched, breathy moan that made Matthew's heart skip a beat. Her dress grazed his thick thighs and hung off the lab table.

"God, I love how big you white men are," Kallie said, her eyes half-open as she basked in the moment.

Matthew groaned deeply as she lowered herself further. She struggled with the last inch, but once she finally got the last of his length in, she sighed, satisfied with how full he made her. Kallie had enveloped him completely.

Dropping his head back, Matthew felt rings of fat bury his chins, making his face a sweaty, pink-ish moon. His nose had rounded out considerably, and he could see his cheeks out of more than the corner of his eye.

"You love how this feels, don't you," Kallie said as she slowly started to ride him. God she felt good. He'd been dating her for only a month, but she was the perfect Japanese girlfriend.

The old Matthew was barely a memory as he faded away in his own mind. Gone were the days of blonde chicks.

Memories of Kallie passionately sucking his dick under his gamer desk while he played Valorant swarmed his mind. Kallie at the dinner table with his family, Kallie holding his hand as they walked down the school hallways, getting eye-rolls from Asian guys who lingered by the lockers. His mind was filled with math equations and the names of famous physicists.

It all bombarded him at once.

The shirt he'd been wearing grew slightly, but still stayed tight on his skin as it turned into a black graphic tee with Kanji on it. It slid back down until it just barely covered his belly button. A pair of glasses materialized onto his face, complementing the braces that locked his teeth into place.

"Hng..." he groaned, feeling his dick twitch as he got closer to cumming. His Japanese girlfriend was just too good, he thought to himself.

Kallie grinned as she leaned over him until they were almost face-to-face. She could tell that he was completely anew. She masterfully sped up as she rode him, putting her hands on his wobbly chest to steady himself.

The black ribbons slipped off the table, allowing Matthew to take his pudgy hands and grip her thin waist. She stopped moving back and forth, letting him dictate how quickly she moved. He started to push and pull her more forcefully, slamming her down harder onto him and causing huge smacks as she collided with his fattened groin.

He came quickly, sending a load deep into Kallie. Matthew groaned deeply as she fell into his chest, gasping at the added weight. Matthew's mind was addled completely. All he could think about was the perfect, tiny Japanese girl whose pussy slowly released his softening member, which was leaking cum as they panted in the after-haze.

**

The next day, Mr. Kent called Matthew's name out in class. No response.

"He's probably lumbering around in the library with that girlfriend of his," a boy shouted out, making the whole class snicker.

Mr. Kent raised his eyebrow, unamused. He moved to tell the boy to be quiet when the classroom door swung open.

A large, rounded boy wearing khakis and a black graphic tee shuffled through the doorway. He looked down, almost causing his thick glasses to slip off his nose, which was oily from the latest round of acne he was suffering from.
