Chubwolf 21 Day 16: Starter Belly / Superchub
21 Days of Chubwolf
This fic may contain Stiles with a tiny starter belly, established relationship Sterek, fit!Derek, belly worship, teasing on both ends, and slight feedisty dirty talk~ PWP basically
Stiles was sprawled on the couch, ridiculously huge punch bowl of Lucky Charms in his hands. He was shoving dripping spoonfuls of cereal into his mouth between giggles at the cartoon he was watching. It was 1pm but he’d probably only recently woken up, judging by his crazy bedhead and stubble. He was in a pair of Star Wars boxers and a worn, too-small T-shirt that didn’t quite cover his belly anymore so there was this little roll of pudge peeking out. Derek stood in the doorway admiring the view until Stiles pushed his glasses up his nose, and said, “Hey, babe,” through a mouthful of food.
Derek dropped his gym bag at the door and toed out of his running shoes before coming to stand in front of his boyfriend, looking him over nice and slow. “Uh, whatcha doin’?’” Stiles asked.
“Just looking.”
A lazy grin spread on Stiles’s face and he stretched out his arms. His T-shirt rode up a little more, so the plump little roll of his belly was out in the open. “See anything you like?”
“You could say that.”
The hand not clutching Stiles’s cereal bowl came up to tug at the hem of Derek’s T-shirt, slightly damp from shower water. Derek leaned in and pressed a kiss to his sugary lips.
He trailed kisses from Stiles’s jaw down to his neck, pleased when he tilted his head back and hummed appreciatively. Stiles lifted his bowl out of the way. “Nice to see you too, big guy.”
Derek dropped down onto the couch beside Stiles, but kept his arm wrapped around him, petting his stomach. He lifted the T-shirt above Stiles’s belly button and said, “Keep eating, don’t mind me.”
“Um, okay.” Stiles’s breath was shallow and he shifted down in his seat to give Derek better access. For a second, Derek thought he might get too distracted to eat like Derek told him to, but Stiles picked up the bowl and kept shoving cereal in his mouth once he got used to the sensation of Derek’s fingers.
He tickled lightly at the trail of dark hair that ran from Stiles’s belly button down below his waistband. “I like when you’re all affectionate,” Stiles said.
“Mhmm,” Derek said, totally enraptured by the way Stiles squirmed under his touch, by the way the light coating of pudge on his belly squished in his hands. He needed to feel it against his lips.
Stiles finished up a big slurp of cereal and set the bowl next to him on the other side of the couch. He hummed deep in his throat, stomach muscles tensing underneath his gut. Derek drew back a little to look up at Stiles. Watched him lick milk off his lips, leaning back with his bloated little stomach exposed, looking satisfied. Derek wanted.
“‘S nice,” Stiles said, eyes fluttering shut.
“Mhm, sure is.” Derek couldn’t resist teasing him a little. He patted the side of Stiles’s stomach to feel it jiggle against his palm and smiled at him. “You’re getting a little soft, Stiles.”
“Wh-at, shut up!” Stiles squawked, half-indignant, half-laughing as he shoved at Derek’s shoulders playfully. “I am not!”
“Yeah?” Derek said, gathering up a nice handful of pudge. “What do you call this then?”
“That… I’m… for your information--” Derek kneaded at his lower belly as he spoke, and Stiles’s hips shifted into it in little helpless movements. “Oh. Um.”
“Yes, Stiles?”
“Okay… well, maybe I’ve been overdoing it a little.” Stiles was blushing, but he was still smiling a little and smelled more like contentment and simmering arousal than embarrassment.
“A little,” Derek huffed, poking Stiles’s belly.
Stiles laughed. “Okay, fine! Whatever. It’s all your fault though so you can’t complain.”
“Not complaining.” Derek spun off the couch and onto the floor, kneeling between Stiles’s soft thighs so he was face to face with Stiles’s gut. He took it in both hands, kneading it from the side. “How is this my fault again?”
Stiles was panting now, looking halfway to blissed out just from Derek touching his belly. He was so sensitive, always had been, but the chubbier parts of him seemed to crave touch, now. His thighs, his ass, his love handles, his softening pecs that Derek just knew would get nice and fat if Stiles kept gaining weight like this.
“You. You’re an enabler, is what you are.”
Derek tried to smother a grin. “Oh yeah? Whatever makes you say that?”
“You know exactly why, asshole. Don’t play innocent with me.” Derek rested his forehead on Stiles’s belly and laughed.
“I don’t know what you’re talking about,” He said against Stiles’s skin, running his lips and scruffy cheeks over his stomach.
“Oh, god,” Stiles whispered, trembling. Derek placed a kiss right below his bellybutton and his flesh gave under the light pressure of Derek’s mouth. It was fucking incredible.
Stiles gasped. “Wow, that. That feels good.” He grabbed Derek’s hair and pulled a little, urging him just a little closer. Derek licked at his skin, salty and so, so soft. “Oh.”
Derek pulled back just enough to ask, “Yeah?” before diving back in to kiss Stiles’s belly open-mouthed, tongue stroking against his skin.
“Oh, god. Yeah, really good. Like, holy god.”
Overwhelmed at how much Stiles seemed to be enjoying himself, Derek buried his face in Stiles’s fat, kissing him just on the edge of desperate. It was everything he’d dreamed; warm and plush and doughy. He pulled a little mouthful between his lips and sucked on it, laving it with his tongue.
Stiles gripped the leather of the couch and it creaked in his fists. “Fuck.”
“You’re gonna spill your cereal,” Derek said, smug, and more composed than he actually felt.
Stiles, on the other hand, sounded like a total wreck. Derek leaned back in to plant little kisses on his belly while he spoke. “Ah. Well it’s-it’s a good thing we’ve got like... five more boxes thanks to your last shopping trip, enabler.”
“Wow, you’re gonna waste all my hard earned money like that?”
Stiles laughed, breathless. “Hard-earned, my ass, you rich asshole. Mmm. You’re the-the one who’s distracting me from my delicious cereal heaven, anyway. So again, this is a-all your fault.”
Derek leaned back, rocking against his heels as if to get up. “Oh well if that’s how you really feel…”
But Stiles’s fingers latched onto Derek’s hair and neck, pulling them back in with a grip that might have bruised if his skin wasn’t already healing. “Don’t you fucking dare stop. God.”
Derek grinned, reveling in the scent of lust emanating from Stiles, his rapid heartbeat ringing in his ears. He could feel Stiles’s cock under his chin, begging for attention. But Derek wasn’t done yet.
As he touched Stiles’s with his hands and mouth, reverently, wherever he could reach, Derek thought about how drastically his body had changed, even over these last couple of months. How much his appetite had increased and how all the thousands of extra calories sat now on Stiles’s paunchy little starter belly. Derek’s lips tingled at the feeling of it against them, jiggling slightly with all the impatient little movements of Stiles’s hips.
Stiles’s belly groaned and grumbled, full of food and milk. With his face pressed against it, Derek could hear it so clearly and he wondered if Stiles knew how much it affected him. All of this. If he was too distracted to think about it right then, Derek knew he’d figure it out later. But for now, Stiles was damn near writhing beneath him, as much of a mess as Derek was.
“I hope you know this is going to do nothing whatsoever to make me stop getting f-fatter, ah.”
“Fuck.”
Derek shuddered. The thought made him ache to touch himself, but he couldn’t bare to take either of his hands away from Stiles’s skin. He wondered how he lost the upper hand so quickly, or if he ever really had it in the first place. Of course Stiles would figure him out.
But he smiled, breathed in deep the scent of Stiles’s desperation. He said, “And why would I want to do that?”
“I-I guess you wouldn’t, would you?” he said, one hand petting Derek’s hair. “You want me to keep getting fat, don’t you, Derek?”
Derek could hear the smug smirk in Stiles’s voice, infuriating and hot. He growled in the back of his throat, feeling the prickle of claws against his fingertips, aching to come out. But he held back so he could keep caressing the softness of Stiles’s curves.
“Yeah, that’s right. You wanna fatten me up. That’s why you’re always buying me so much food, huh?”
Derek gasped. He lifted his head to look up at Stiles, who looked debauched but thoroughly amused. Derek could feel his eyes bleed electric blue. “Did you ever think that maybe some of that food was for me?”
“Oh, yeah, my bad. You make sure the house is always stocked with my favorite fatty junk foods because you want to eat it. But somehow you never do. Makes sense.”
“Well you’re the one who eats it all. Don’t blame me for this little belly, that’s all you.”
“Yeah, yeah, just admit it, buddy!”
“Admit what?” Derek raised his eyebrows innocently and teased lightly at Stiles’s gut with his teeth.
“You know what. God-dammit that feels-”
“Okay,” Derek said. He stroked his hands down Stiles’s sides, skimming his love handles and coming to settle on Stiles’s meaty thighs. He couldn’t resist leaning his head down to catch the supple inside of one between his lips. It made Stiles gasp and his hips buck up, needy. His eyebrows drew tight together and he looked about ready to lose it for all that he was snarking at Derek just a few seconds ago.
“Stiles.” Derek realized his own voice has gone throaty and thick, his teeth sharp, filling up his mouth. He closed his eyes, tried to calm down and breathed in deep. In a moment he felt them retract, but he still saw through his wolf eyes when he opened them again.
“Yeah?” Stiles asked. It took Derek a moment to respond. He’d almost forgotten what he’d been trying to say, distracted by the hitched breaths Stiles made when Derek grasped at the fat on his thighs and how from this angle the softness around his face looked more like a double chin.
“You’re right,” Derek said.
Stiles grinned, triumphantly. “Ah-about what, Derek?”
Derek rolled his eyes, annoyed at having to say it. To give voice to the thoughts that had been plaguing him since Stiles started to gain weight. “I want to,” Derek grit out. “I like you fat.”
“Yeah I kind of got that,” Stiles huffed, too breathless to be a laugh. “But I’m not fat yet, dude.”
Awestruck, Derek brought one hand up to frame Stiles’s belly and repeated, “Yet.”
“Ah, shit. You keep encouraging me like this and I will be.”
“Fuck,” Derek whispered. He hid his face in Stiles’s gut, gulping in strained breaths. Almost without thinking about it, Derek’s free hand slid down to touch himself through the flimsy fabric of the sweats he’d changed into after his shower.
Stiles’s fingers dragged through Derek’s hair and he said, “You want to make me fat, don’t you?”
Derek whined, tracing the outline of his dick, feeling too close just from the thought of it. He lifted his face up and looked into Stiles’s eyes. “Yes. I hoped you would. I want...”
Stiles didn’t look smug anymore. He looked like he was barely holding himself together, like he was almost pained by it, but the overwhelming feeling of Stiles’s lust choking the air had Derek surging up half a second before Stiles grabbed his shirt and slurred, “C’mere.”
He kissed Stiles like his lips gave him the air in his lungs. Like they hadn’t kissed since the first time, sloppy and unrestrained. Derek stood up and cradled Stiles’s jaw in both hands, tilting his head against the back of the couch. Stiles whined and pulled Derek down by his ass and the backs of his thighs until he was straddling Stiles’s waist. He pressed himself flush against Stiles’s belly, its softness against his abs, and he started to grind into it in helpless little thrusts.
His human teeth grazed Stiles’s bottom lip and it made him let out a shaky moan. Derek put his mouth to Stiles’s ear and said, “I want to make you fat.”
Stiles moaned again, loud. He was gripping Derek’s muscular thighs and letting out little sounds on almost every breath, noisy like he got when he was close. Derek rocked his ass against Stiles’s dick, his own trapped in the cushion of Stiles’s belly fat. He was close too.
“Can I tell you something?” Stiles whispered, voice low and gravelly against Derek’s temple. “Oh, fuck. I. I’m--”
“Stiles.”
“Ah-I want you to. God, I want. Want you to fatten me up, Derek.”
Derek shuddered and kissed him, filthy wet. That confession was ringing in Derek’s ears; Thoughts of Stiles bigger, fatter were echoing in his mind’s eye. A pulse of heat rushed through him; He came grinding against Stiles’s belly, so suddenly it shocked the air out of his lungs.
And then Derek was slumped against Stiles, pliant and loose, but Stiles was still restless beneath him. He groaned and thrusted up against him, gripping Derek’s ass to move him just where he wanted, and then Stiles was coming too, whispering, “Fuck, fuck, Derek.”
One of Derek’s hands wound up against the side of Stiles’s little potbelly, patting him absently as he shivered through aftershocks. He rubbed his cheek against Stiles’s throat, nuzzling, scenting him.
“Freak,” Stiles said, lovingly.
“Takes one to know one.”
“Oh my god, you loser. What are you, ten? Anyway you’re not allowed to call me a freak. Not when you want me to get fat for you, what the hell, honestly.”
Stiles shifted under his hands like the feeling was still making him crazy, like he could get hard again soon. Derek grinned. “But you want to. So like I said, takes one to know one.”
He rolled his eyes. “Pff, whatever. You’re the one who gave me the idea. You were all, you know,” Stiles flailed his hands, “Into it. It sort of stuck in my head, you know? And one thing led to another… And, okay, maybe I would’ve gotten there myself eventually, because it’s pretty. Wow, awesome. For real. I don’t want you to think I’m not into it, cause I’m like all in. But still. I still say you’re the freakier freak.”
“Okay,” Derek laughed. “You knew? Before?”
“I had my suspicions. Also you should learn to delete your browser history.”
Derek swatted at Stiles’s shoulder lightly. “You went through my browser history?”
“It was an accident!” Stiles yells, laughing.
“Sure it was.”
“It totally was! Sort of. But you get a big fat boyfriend out of it, that’s gotta count for something.”
Derek looked down at his fingers poking at Stiles’s little belly and tried to hide his smile. “I don’t know… Like you said, you’re not really fat yet. I think you’re gonna have to make it up to me.”
“Oh yeah? How’s that?”
“Hmm. How about I make you something to eat?”
“Oh my god, seriously? That’s my punishment? Derek. Babe. This is the best thing that’s ever happened to me.”
Derek grinned at his boyfriend, but something in his expression must’ve read as predatory because Stiles suddenly looked a little wary. “Oh my god what?”
“Nothing. I just hope you’re hungry, Stiles.”
“Pff, is that a challenge? Come on, you know me. I’m always hungry.” Stiles poked his chest. “Bring it on. Do your worst, wolfy.”
Derek couldn't help himself. He kissed Stiles deeply, loving the way his slight softness felt between his thighs and under the palms of his hands. But Stiles pulled away, lips slick and said, “Now come on, chop chop.” He patted Derek’s ass. “I’m not gonna get fat from awesome sex, okay? Actually, maybe I could. We could have all the food sex. Oh my god. This is gonna be awesome-”
Derek kissed him quiet.
