Chubwolf 21Ā 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 heād 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 didnāt 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, āHey, babe,ā 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. āUh, whatcha doinā?āā Stiles asked.
āJust looking.ā
A lazy grin spread on Stilesās 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. āSee anything you like?ā
āYou could say that.ā
The hand not clutching Stilesās cereal bowl came up to tug at the hem of Derekās T-shirt, slightly damp from shower water. Derek leaned in and pressed a kiss to his sugary lips.
He trailed kisses from Stilesās jaw down to his neck, pleased when he tilted his head back and hummed appreciatively. Stiles lifted his bowl out of the way. āNice to see you too, big guy.ā
Derek dropped down onto the couch beside Stiles, but kept his arm wrapped around him, petting his stomach. He lifted the T-shirt above Stilesās belly button and said, āKeep eating, donāt mind me.ā
āUm, okay.ā Stilesās 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 Derekās fingers.
He tickled lightly at the trail of dark hair that ran from Stilesās belly button down below his waistband. āI like when youāre all affectionate,ā Stiles said.
āMhmm,ā 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.
āāS nice,ā Stiles said, eyes fluttering shut.
āMhm, sure is.ā Derek couldnāt resist teasing him a little. He patted the side of Stilesās stomach to feel it jiggle against his palm and smiled at him. āYouāre getting a little soft, Stiles.ā
āWh-at, shut up!ā Stiles squawked, half-indignant, half-laughing as he shoved at Derekās shoulders playfully. āI am not!ā
āYeah?ā Derek said, gathering up a nice handful of pudge. āWhat do you call this then?ā
āThat⦠Iām⦠for your information--ā Derek kneaded at his lower belly as he spoke, and Stilesās hips shifted into it in little helpless movements. āOh. Um.ā
āYes, Stiles?ā
āOkay⦠well, maybe Iāve been overdoing it a little.ā Stiles was blushing, but he was still smiling a little and smelled more like contentment and simmering arousal than embarrassment.
āA little,ā Derek huffed, poking Stilesās belly.
Stiles laughed. āOkay, fine! Whatever. Itās all your fault though so you canāt complain.ā
āNot complaining.ā Derek spun off the couch and onto the floor, kneeling between Stilesās soft thighs so he was face to face with Stilesās gut. He took it in both hands, kneading it from the side. āHow is this my fault again?ā
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.
āYou. Youāre an enabler, is what you are.ā
Derek tried to smother a grin. āOh yeah? Whatever makes you say that?ā
āYou know exactly why, asshole. Donāt play innocent with me.ā Derek rested his forehead on Stilesās belly and laughed.
āI donāt know what youāre talking about,ā He said against Stilesās skin, running his lips and scruffy cheeks over his stomach.
āOh, god,ā Stiles whispered, trembling. Derek placed a kiss right below his bellybutton and his flesh gave under the light pressure of Derekās mouth. It was fucking incredible.
Stiles gasped. āWow, that. That feels good.ā He grabbed Derekās hair and pulled a little, urging him just a little closer. Derek licked at his skin, salty and so, so soft. āOh.ā
Derek pulled back just enough to ask, āYeah?ā before diving back in to kiss Stilesās belly open-mouthed, tongue stroking against his skin.
āOh, god. Yeah, really good. Like, holy god.ā
Overwhelmed at how much Stiles seemed to be enjoying himself, Derek buried his face in Stilesās fat, kissing him just on the edge of desperate. It was everything heād 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. āFuck.ā
āYouāre gonna spill your cereal,ā 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. āAh. Well itās-itās a good thing weāve got like... five more boxes thanks to your last shopping trip, enabler.ā
āWow, youāre gonna waste all my hard earned money like that?ā
Stiles laughed, breathless. āHard-earned, my ass, you rich asshole. Mmm. Youāre the-the one whoās distracting me from my delicious cereal heaven, anyway. So again, this is a-all your fault.ā
Derek leaned back, rocking against his heels as if to get up. āOh well if thatās how you really feelā¦ā
But Stilesās fingers latched onto Derekās hair and neck, pulling them back in with a grip that might have bruised if his skin wasnāt already healing. āDonāt you fucking dare stop. God.ā
Derek grinned, reveling in the scent of lust emanating from Stiles, his rapid heartbeat ringing in his ears. He could feel Stilesās cock under his chin, begging for attention. But Derek wasnāt done yet.
As he touched Stilesās 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 Stilesās paunchy little starter belly. Derekās lips tingled at the feeling of it against them, jiggling slightly with all the impatient little movements of Stilesās hips.
Stilesās 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 heād figure it out later. But for now, Stiles was damn near writhing beneath him, as much of a mess as Derek was.
āI hope you know this is going to do nothing whatsoever to make me stop getting f-fatter, ah.ā
āFuck.ā
Derek shuddered. The thought made him ache to touch himself, but he couldnāt bare to take either of his hands away from Stilesās 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 Stilesās desperation. He said, āAnd why would I want to do that?ā
āI-I guess you wouldnāt, would you?ā he said, one hand petting Derekās hair. āYou want me to keep getting fat, donāt you, Derek?ā
Derek could hear the smug smirk in Stilesās 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 Stilesās curves.
āYeah, thatās right. You wanna fatten me up. Thatās why youāre always buying me so much food, huh?ā
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. āDid you ever think that maybe some of that food was for me?ā
āOh, 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.ā
āWell youāre the one who eats it all. Donāt blame me for this little belly, thatās all you.ā
āYeah, yeah, just admit it, buddy!ā
āAdmit what?ā Derek raised his eyebrows innocently and teased lightly at Stilesās gut with his teeth.
āYou know what. God-dammit that feels-ā
āOkay,ā Derek said. He stroked his hands down Stilesās sides, skimming his love handles and coming to settle on Stilesās meaty thighs. He couldnāt 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.
āStiles.ā 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.
āYeah?ā Stiles asked. It took Derek a moment to respond. Heād almost forgotten what heād 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. Ā
āYouāre right,ā Derek said.
Stiles grinned, triumphantly. āAh-about what, Derek?ā
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. āI want to,ā Derek grit out. āI like you fat.ā
āYeah I kind of got that,ā Stiles huffed, too breathless to be a laugh. āBut Iām not fat yet, dude.ā
Awestruck, Derek brought one hand up to frame Stilesās belly and repeated, āYet.ā
āAh, shit. You keep encouraging me like this and I will be.ā
āFuck,ā Derek whispered. He hid his face in Stilesās gut, gulping in strained breaths. Almost without thinking about it, Derekās free hand slid down to touch himself through the flimsy fabric of the sweats heād changed into after his shower.
Stilesās fingers dragged through Derekās hair and he said, āYou want to make me fat, donāt you?ā
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 Stilesās eyes. āYes. I hoped you would. I want...ā
Stiles didnāt look smug anymore. He looked like he was barely holding himself together, like he was almost pained by it, but the overwhelming feeling of Stilesās lust choking the air had Derek surging up half a second before Stiles grabbed his shirt and slurred, āCāmere.ā
He kissed Stiles like his lips gave him the air in his lungs. Like they hadnāt kissed since the first time, sloppy and unrestrained. Derek stood up and cradled Stilesās 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 Stilesās waist. He pressed himself flush against Stilesās belly, its softness against his abs, and he started to grind into it in helpless little thrusts.
His human teeth grazed Stilesās bottom lip and it made him let out a shaky moan. Derek put his mouth to Stilesās ear and said, āI want to make you fat.ā
Stiles moaned again, loud. He was gripping Derekās muscular thighs and letting out little sounds on almost every breath, noisy like he got when he was close. Derek rocked his ass against Stilesās dick, his own trapped in the cushion of Stilesās belly fat. He was close too.
āCan I tell you something?ā Stiles whispered, voice low and gravelly against Derekās temple. āOh, fuck. I. Iām--ā
āStiles.ā
āAh-I want you to. God, I want. Want you to fatten me up, Derek.ā
Derek shuddered and kissed him, filthy wet. That confession was ringing in Derekās ears; Thoughts of Stiles bigger, fatter were echoing in his mindās eye. A pulse of heat rushed through him; He came grinding against Stilesās 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 Derekās ass to move him just where he wanted, and then Stiles was coming too, whispering, āFuck, fuck, Derek.ā
One of Derekās hands wound up against the side of Stilesās little potbelly, patting him absently as he shivered through aftershocks. He rubbed his cheek against Stilesās throat, nuzzling, scenting him.
āFreak,ā Stiles said, lovingly.
āTakes one to know one.ā
āOh my god, you loser. What are you, ten? Anyway youāre not allowed to call me a freak. Not when you want me to get fat for you, what the hell, honestly.ā
Stiles shifted under his hands like the feeling was still making him crazy, like he could get hard again soon. Derek grinned. āBut you want to. So like I said, takes one to know one.ā
He rolled his eyes. āPff, whatever. Youāre the one who gave me the idea. You were all, you know,ā Stiles flailed his hands, āInto it. It sort of stuck in my head, you know? And one thing led to another⦠And, okay, maybe I wouldāve gotten there myself eventually, because itās pretty. Wow, awesome. For real. I donāt want you to think Iām not into it, cause Iām like all in. But still. I still say youāre the freakier freak.ā
āOkay,ā Derek laughed. āYou knew? Before?ā
āI had my suspicions. Also you should learn to delete your browser history.ā
Derek swatted at Stilesās shoulder lightly. āYou went through my browser history?ā
āIt was an accident!ā Stiles yells, laughing.
āSure it was.ā
āIt totally was! Sort of. But you get a big fat boyfriend out of it, thatās gotta count for something.ā
Derek looked down at his fingers poking at Stilesās little belly and tried to hide his smile. āI donāt know⦠Like you said, youāre not really fat yet. I think youāre gonna have to make it up to me.ā
āOh yeah? Howās that?ā
āHmm. How about I make you something to eat?ā
āOh my god, seriously? Thatās my punishment? Derek. Babe. This is the best thing thatās ever happened to me.ā
Derek grinned at his boyfriend, but something in his expression mustāve read as predatory because Stiles suddenly looked a little wary. āOh my god what?ā
āNothing. I just hope youāre hungry, Stiles.ā
āPff, is that a challenge? Come on, you know me. Iām always hungry.ā Stiles poked his chest. āBring it on. Do your worst, wolfy.ā
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, āNow come on, chop chop.ā He patted Derekās ass. āIām 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-ā
Derek kissed him quiet.
