One Direction Weight Gain One-shots

The Fat Stealer (LARRY)

Harry was tired of being skinny. He was sick of people assuming that he survived on a diet of steamed celery and cardio, when in fact, it was more like the complete opposite. With the long haired lad regularly consuming vast amounts of greasy, fatty fast foods, in quantities significant enough to peeve his friends who had more traditional metabolisms; Such as Niall, who had ballooned in weight since starting university. Or Liam, whose bulk was now very much a dirty bulk. Or even Louis, whose baby fat staying with him throughout his adolescence and continued to grow well into his adulthood.

They very much envied their lanky friend, who could eat whatever he wanted without gaining a single pound. However, Harry hated this, he hated being so tiny, his arms were no bigger than his sisters and he actually weighed 20lbs less than her too.

Harry tried to change this, but all the gym memberships and stuffing sessions in the world couldn't change anything, and Harry soon gave up on trying. Not quite accepting his skinny body, but beginning to come to terms with it.

However, this all changed one fateful day, when Harry, along with Liam, Niall and Zayn went to Louis, a.k.a Harry's boyfriend, in hospital, after he had fallen and broken his arm.

They entered into a friendly conversation for a good twenty minutes, where Louis let his mates know that he was allowed to go home today after having an x-ray that showed no permanent damage to his arm.

Harry, ecstatic to have his boyfriend home so soon, decides to treat him to lunch, running down the hallway trying to find the canteen, and naturally getting very lost along the way. Soon enough Harry is panting and out of breath, still nowhere near the canteen. Slowly he looks around, not at all recognising where he is. Harry figures he should ask someone for help, and decides to knock on the closest door to him.

The door swings open, and Harry nervously steps in, seeing that he is in some type of laboratory. His curiosity gets the better of him and he starts to wander around, wanting to reach out and touch all the cool things appearing in his peripheral vision. When he goes to poke a small nozzle his suddenly gets sprayed with a putrid smelling substance which has him falling over and coughing violently.

Harry's vision begins to darken, before he dozes off in the empty laboratory...

.  .  .

"Excuse me sir, I'm going to have to ask you to leave." An unimpressed voice jolts Harry awake, who scrambled out of the now not at all empty laboratory.

Harry's phone starts to ring, so he answers it to hear his mates shouting at him to hurry up, and that Louis wants to go home already. Apparently he was out long enough for Louis to get discharged.

Carefully following a hospital map that he happened past, Harry eventually found his way to the entrance, where Louis was tapping his foot impatiently, while Liam looked bored and Zayn was asleep. Harry assumed Niall was off somewhere eating, which turned out to be true, as the doughy Irish lad waddled into his vision, hands stuffed to the brim with chocolate and other deliciously unhealthy foods.

"Took you long enough boo, I'm hungry!!" Louis screeched, hugging Harry to his soft chest with his non injured arm. Harry snuggled into Louis, before swiping two of Niall's snacks, passing one to Louis and keeping the other for himself.

"Sorry love." Harry spoke, kissing Louis' cheek.

"Let's go home."

.....

Having dropped Zayn and Niall off at their shared apartment, Harry and Louis arrived back at their own flat, with harry being a gentleman and holding a hand out to help Louis out of the car.

"Why thank you, sir." Louis winked and made sure to swing his hips as he walked in the way that he knew would drive Harry absolutely crazy.

Louis turned to look at his boyfriend, and sure enough, his gaze was centred on Louis bulging curves. He was sure he could see drool coming out of Harry's mouth too. Louis giggled, he loved teasing people with his ass, it was one of the very best things about being big.

After calming down from being subjected to the perfection that was Louis' rear end, Harry made sure to pamper his boyfriend all evening. He made sure that Louis wouldn't have to move a single muscle, instead he could just sit on the couch, sucking down one of Harry's signature thickshakes. Louis sometimes had up to three of them a day, which surely contributed to his ever growing curves.

Harry wished that he could gain weight that easily, but he settled for watching his boyfriend grow thicker and thicker with the help of his cooking.

After a massive dinner, which ended with both Harry and Louis stuffed to the limit, the two lovebirds helped each other back to their bedroom and began to strip to their boxers; Harry in a pair of black boxers and Louis in a stretched pair of bright blue briefs, which only managed to contain a fraction of his round bottom. Harry just had to feel those curves, and slowly run a large hand over his boyfriend, who purred from the contact.

Harry felt Louis expansive body, his love handles, his ass and his full back. Resting his hands comfortably onto Louis' bubble butt, Harry began to imagine what it would be like to have a body like Louis. Slowly losing himself to the desire to grow, he began to knead the bulbous cheeks that dominated his eyesight, he was too far gone to hear Louis' audible moans getting louder and louder.

Louis meanwhile was in heaven. He couldn't help by cry out when Harry's large hands starting massage his body. Leaning into his boyfriend as he became more and more relaxed, and more than a bit sleepy too. As Harry continued massaging, Louis felt a weird numb sensation go over him, originating form his ass.

Harry also felt something weird, but rather than feeling tired or numb, he felt exhilarated. Also quite a bit tingly too, especially in his ass. Taking a quick glance towards his rear he saw his ass cheeks slowly expanding in girth, pushing against his boxers. Harry had to bite his lip to try and control himself, because whatever was happening to him, he didn't want it to stop anytime soon.

Looking back to his curvy boyfriend, Harry couldn't help noticing that Louis' enormous rear end wasn't stretching his briefs as greatly as it was before. And then the realisation hit him. He had taken fat from Louis' ass and given it to his own.

So many possibilities were running through Harry's head now, all centred around draining his boyfriend of his curves and putting them onto himself instead. Harry needed to do this, he always wanted to be bigger, and now he finally has a chance at getting what he desires.

Moving his hands around and onto Louis' belly, who had fallen asleep during the last transfer, Harry thought of all his biggest fantasies; waddling down the street, overhang slipping out of his shirt. Breaking his furniture because of how much weight he gained. And his biggest fantasy of all; outweighing Louis.

Harry groaned in pleasure when he felt the tingly feeling once again, this time throughout his whole body. Harry was on cloud nine, watching himself slowly grow fatter and fatter, while his boyfriend slowly shrank. Soon enough there was significant pressure on Harry's boxers, until they finally burst, sending Harry's massive cheeks oozing through the remains.

Harry looked down at himself, seeing that he had grown a round flabby belly and a pair of perky man boobs, he jiggled them, happy when they grew even bigger in his hold. A loud snap brought Harry's attention back to his hips, which had destroyed the last of his boxers.

As Harry grew ever larger, he looked back at the sleeping Louis. He laughed and shook his huge gut, wondering how shocked the now smaller lad would have upon waking up tomorrow. Harry had to guess that Louis looked around 140 pounds now, where before he was nearing 300. That means that Harry has put on a potential 160lbs, which brings him to almost 340lbs!

Harry made sure to stop the transfer so that Louis wouldn't get too small, and then took inventory of his gains; Huge moobs? Check. Giant ass? Check. Massive gut? Check. Tiny adorable boyfriend? Check!

"Perfect" Harry thought, pulling the now tiny Louis into his arms, and resting his head against his moobs. Harry couldn't wait to see what Louis thought tomorrow, and his friends, they would be very shocked as well.

Maybe you could steal their fat too.

Hmmm...

"Good idea." Harry smirks to himself.
