Haruhi was so comfortable in her relationship with Tamaki, as anyone should be with their significant other. Something that started off unsure and a bit awkward blossomed into something so warm and sweet. Being with Tamaki felt like the emotional equivalent of pulling on an oversized jumper at the end of a long work day, a soothing balm to ease the tension in her shoulders.

Of course, having gotten together at the age they were, they kept each other company as they blossomed in… other ways. They didn't have sex to start with, neither feeling ready to take the plunge into that unfamiliar territory, but heavy petting and a little dirty talk over the phone was dipping their toe in. Tamaki liked her praising him, but he also liked to be straddled and his hair pulled. She loved how pliant and willing to please he was, calling him puppy as a joke.

She also realised that she loved the hint of softness around his waist. It could barely be classified as pudge but, one night when she was alone and had her hand in her underwear, she couldn't help but think… What if he had a little more? A cute, pudgy tummy that pulled his shirts taught, buttons overtasked. She couldn't help but moan, feeling even more wet and desperate than when she started. What if they both went to 'all you can eat' restaurants and on bakery dates. What about the flush that would stretch across Tamaki's full, rounded cheeks when he could no longer pull his jeans higher than mid-thigh?

She came surprisingly quickly, thinking of scenarios with her boyfriend a bit pudgier. Maybe even fat. It was unusually attractive to her, and she berated herself for not realising that kink sooner, with Tamaki's obsession with all things commoner in high school. A few more sweets here, a few fast food restaurants there. Thick milkshakes and ice cream. But no, she knew that discussing it was the best way forward, like with anything of this nature. She was nothing if not practical.

Tamaki was… surprised. He wasn't really expecting it, especially as a lot of emphasis had been put on his lean… ish, muscular figure in high school. Still, as always, he was willing to try so long as Haruhi would be happy. Ground rules were set, like not being ridiculed because of the extra weight, and they had to stop if either of them became dissatisfied with the situation for any reason. Just basic things, that could be subject to change, but the trial period had begun.

Tamaki took to eating whatever his heart desired, whenever he wanted. Not to mention how much, not limiting his portions like before. He moaned around mouthfuls of expertly baked eclairs at work, ate whatever he wanted for lunch, and Haruhi always had a very sizable dinner waiting for him whenever she got home first.

She'd straddle his thighs, cooing and calling him a good boy as he ate forkful after forkful that she offered. She'd grind down on his hard on during the feedings, also, saying that it was a reward for eating as much as she could, telling him all the dirty things she wanted to do to him. How cute his wider hips were, how she'd be able to spank him longer with the lovely padding on his ass, how she'd grind against his fat belly – when he was bigger.

Of course, that was a good sixty pounds ago, and Tamaki… really loved being her pampered little pet. The extra chub was warm and soft, and his fuller cheeks made his smile even prettier. He even found himself playing with his round, flabby gut when laying in bed, and it only helped get him off when Haruhi was working straight through the night in order to get every possible detail of her case down perfectly. Of course, she'd always give him a call to encourage him to eat even more than before, feedings turning into stuffings, and he'd massage his taught stomach and imagine her small, soft hands doing it for him before she'd take care of his other problem.

Now, however, he was stuffed beyond anything he could remember. He'd never felt so full, his belly letting out the odd gurgle of discontent with how stretched it felt. He'd worn his baggiest top, but he'd eaten so much that it was pulled over the mound of his gut, a sliver of tanned skin exposed. He shouldn't have eaten that much, especially as they were in public, but Haruhi was being so sweet and praising him with every bite, and he greedily ate up both her compliments and the stupid number of deserts they'd ordered.

Haruhi's cheeks were pink also, but from how she was squirming in her chair, he doubted that it was all from embarrassment. Her eyes were glistening with pride and lust, not to mention love. He adored that expression on her.

"I think we need to go home. Now," She murmured somewhat hurriedly, "You got me all wet for you, eating all that. I didn't know you could eat all that, but I'm so glad we ordered it all. You're an amazing man, Tama. So beautiful. So cute, all stuffed and out of breath…"

He also loved when Haruhi rambled. She'd give him so much admiration, and he beamed from it every time. It was worth the effort to get up, and the near-waddle he had from being so stuffed. Even the stares of the patrons were becoming a point of pleasure, as they could all see how big his beloved Haruhi was making him. He even got treated to a belly rub as they were driven home, the back of the taxi muted so the driver couldn't hear them, and he had the pleasure of watching Haruhi try to stay discreet as she fingered her wet, deliciously aching clit.

She all but threw the money at the driver, helping him up the few steps to the front door as his food certainly hadn't gone down enough to walk comfortably, and almost leapt on him as soon as the door was closed. She groped his belly, hands gliding over his love handles and side rolls before squeezing his ass, and he mewled against her hungry, aggressive lips.

"You're getting so big," She moaned, lips pulling away from his to lavish attention on his neck, making him gasp and his dick harden. He certainly had gotten rather fat, but he wanted more to. He loved this, and it made him feel good, even if the rumour mill was ever-churning, "You're so hot. Eating all that without a care that people were watching. You're biggest shirt's too small, and you're just so beautiful…"

She pulled away for a moment, hands cupping and lifting his belly before letting it go, and Tamaki could only gasp as his heavy, overfed stomach jiggled heavily, even going so far as to brush the tent in his pants.

"You're so soft and jiggly now… Let's get you weighed and find out how much fatter you're going to get," Haruhi grinned, all but pulling him along to the bathroom, nearly ripping his clothes off along the way. Not that he was complaining.

Without the shirt and trousers compressing his stomach, he could see that it was bulging out a bit further than before. Any further, and he wouldn't be able to see his toes, even if he did try squishing his belly down. He didn't mind. Not really, anyway. He was just wondering how far this was going to go before it'd feel like enough for either of them. He loved not worrying about his figure and eating to his heart's content, Haruhi admiring him all the way, and she loved his fat belly, thunder thighs, and his butt.

The digital beep of the scale broke the trance he was under, and he stepped onto the metal surface, the numbers surely rising but a little obstructed due to his bloated belly.

"Oh God Tamaki… I need you in bed right now," Haruhi gasped, looking up at him with stars in her eyes, "Two hundred and sixty four pounds..."

He was sure anyone else would either be mortified or think that was plenty. However, he couldn't help but say the first thing that'd popped into his head.

"How about we go for over three hundred? At least."
