Chapter Text
The lights went on automatically when they entered Hunk’s room and the brightness of it felt glaring after the dim corridor. Hunk grunted, reaching for the panel that controlled the lights. “Let’s not ruin the mood,” he said quickly, glancing at Shiro sideways.
He didn’t know how to respond, so he conceded to nodding, following Hunk to his bedside in silence. The whole situation left him wordless--it was everything he had been dreaming about, every mad thought that had occupied his mind over the past several weeks suddenly realized--and he didn’t know how to proceed.
Shiro watched Hunk sit down on the edge of his bed with a sigh of relief, and his attention was drawn on the huge ball of a gut in his lap. It made his usually loose shirt look ridiculously small now, not riding up but tight.
“Hey, it’s okay.”
His eyes snapped up to Hunk’s face, his cheeks flushing as he realized he had been staring for too long. He wasn’t sure what he had been expecting to see there but Hunk was smiling, soft and just as unsure as he was, his nervousness evident in the crease of his brow.
No, wait. Not nervousness.
“You can lie down,” Shiro said, moving forward with sudden clarity. He sat next to Hunk, and after a fraction of hesitation, he placed his hand on Hunk’s stomach. “This must hurt.”
“Ah, yeah.”
He waited a moment, giving Hunk a chance to move away from his hand, but it was like his touch had anchored them both in place with iron shackles. He could feel heat surging up through his palm, making his heart beat fast again; they were so close now that he could just lean over and kiss Hunk, but--he wasn’t sure if that was part of the deal. “Lie down,” he said again, hiding his doubts behind a tone of command.
Hunk’s movements were awkward, clumsy, his bloated middle coming in the way as he scrambled back on the bed until his head was propped against the pillows. He let out another sigh, then followed it with a long, gurgling burp that seemed to rise all the way up from the bottom of his gut. “Oops,” he said, flushing red. “Sorry.”
“It’s okay,” Shiro said, his voice gruff. “I don’t mind.” He sidled up closer so that he was sitting next to Hunk’s side, and this time he gave no time for hesitation before running his hand over Hunk’s gut in a slow caress.
The food goo had done its job and left Hunk’s stomach feeling solid, too stuffed to budge. In this position it looked even rounder, if that was possible, rising up in an almost perfect curve. Pressing in, Shiro could feel that there was absolutely no give on the top, only a slight layer of fat for his fingers to sink into.
“Relax,” he murmured. He could sense that Hunk was tensing up under his touch, and adding to his discomfort was the least thing Shiro wanted. He needed a distraction.
“Tell me more about your research.”
“Huh?”
Shiro gave him a quick smile. “I want to know how you got the food machine to do all that. And what else you can do with it.”
“Oh, okay, um...” Hunk was quiet for a moment, gathering his thoughts while Shiro kept rubbing his belly in soothing circles. “I mean, not to go into too much detail, you can basically code it to do anything you want.”
“Anything?”
“Yeah, pretty much. And the coding isn’t the hard part--it’s figuring out how to make it taste like real food and not like, you know, food goo. Altean flavors are kinda weird, so first I had to poke around to see what bits of coding make it sweet, what salty, and so on.” Hunk covered his mouth with a fist and burped a couple more times before continuing, “But actually, it’s more about figuring out what our food tastes like, you know? So I know which direction to tweak the code, right?”
“That--sounds like a lot of work,” Shiro said, impressed.
“Yeah, you could say that. It took me weeks just to get those three flavors done,” Hunk said with a chuckle. He was getting into his element now, his hands coming to motion as he continued talking, a familiar note of excitement in his voice. “It would’ve been so much easier if I could just have the machine scan and replicate an Earth dish, but pulling it off with just my taste buds as a guide... Not that easy, lemme tell you. Some of the stuff that came out was, uh. Pretty bad.”
Shiro hummed in reply, letting the information sink in. Given how much Hunk loved food, it wasn’t that surprising for him to pull off something like this, but still--the lengths he’d gone to just to prove Keith wrong seemed like a major overkill.
Unless that was only a part of the reason for his quest.
“Sounds like there was a lot of tasting involved,” he said, trying to keep his voice from betraying his thoughts. “Did you do all the work alone?”
He had kept his hand moving while Hunk talked, slowly widening the circle he was drawing upon his belly to cover it from side to side, top to bottom. Now, he rested his palm just below of the highest part, right where the curve of his bloated stomach started to lead down, and pressed in lightly.
Hunk let out a soft breath, his answer coming just a bit late. “Y-yeah, I mean. Yes.”
“Why?”
Hunk shrugged. “It was supposed to be a surprise, I guess?”
Shiro could feel Hunk’s eyes on him as he slowly traced his fingers over the plump part below his navel. He still wasn’t sure how much further Hunk wanted to take this--how much help was he asking for, exactly--but there was no sign of him pulling back when Shiro moved his hand lower, kneading the fat there eagerly. It felt so big, so doughy yet full... He was momentarily overcome with an urge to rip that offending shirt off to press his face against that fleshy gut to bite it, to feel that pliant skin against his lips.
Shiro cleared his throat, swallowing past the thickness. He felt tense with anticipation, with lust, and he couldn’t keep himself from asking, “And it had nothing to do with you wanting all of it for yourself?”
If Hunk noticed the roughness in his voice, he didn’t show it. “No, no. I just--the others just don’t have the same appreciation for it? I mean, I did think about asking for help, but...” Hunk trailed off, hesitating just slightly before continuing brusquely. “Well, maybe I just don’t trust their palates to be up for the job.”
Shiro felt a smile tugging at his lips. “You don’t?” he asked, patting Hunk’s gut gently to make it jiggle.
“No, I really don’t. You know what Lance’s favorite food was back at the Garrison? Hot Pockets. Fricking Hot Pockets, man! And Pidge wasn’t any better with her cup noodles. I know the food goo ain’t that great tasting, but at least it’s got potential to be good.”
Shiro found himself grinning at Hunk’s outrage; he should have figured that Hunk was a food snob on top of being a big eater. “I don’t know. At this point, I could go for a Hot Pocket just for a change of pace.”
“Oh, don’t you start,” Hunk huffed, crossing his arms over his chest. “If you want change, I can get you some of that red goo that’s like, a thousand times better than any Hot Pocket could ever dream to be.”
“Is that so?”
“Trust me, it is.” Hunk uncrossed his arms again, massaging the top of his gut with a frown on his face.
Shiro watched him for a moment, then moved his hand up to where Hunk’s was. “Still hurts?” he asked softly and Hunk nodded, his face pulling into a grimace.
“Yeah, uh, a bit.”
He knew that Hunk was lying. His forehead was glistening with sweat, his breath still short and laboured, all the tell-tale signs of too much food in his gut written on his body. And with nine bowls of goo stretching his stomach out, there was no way it hurt just ‘a bit’, but--he wasn’t going to press the subject. Instead, he tried to imitate Hunk’s pattern, massaging the tight crest of his belly in silence until Hunk sighed, his head falling back against the pillows.
“You can use both of your hands, by the way.”
His looked up to see Hunk watching him with dark eyes, his expression hard to read. Shiro nodded, but as soon as he brought his other hand--his real hand--on Hunk’s middle, the missing sensations of warmth and softness flooded his system. He exhaled in gust, fighting to keep his face in check while feeling the roundness of Hunk’s belly with both hands.
“Like, like this?”
“Mmm, that’s good, but--” Hunk’s hand suddenly caught his, his fingers running over the prosthetic. “--you should come closer.”
Shiro’s eyes flicked up again, this time in confusion. “Closer?”
“Uh, yeah.” Hunk glanced away, blushing furiously, then focused back on where their hands were touching. “You could sit on my lap if you wanted to.”
A spike of heat speared through Shiro’s body as Hunk’s words registered in his brain. His senses were suddenly sharp as glass, adrenaline pumping through his veins like he was facing an enemy but no, this wasn’t a battleground. He didn’t even think about running this time, moving on instinct; with the lightness of a fighter he rolled up and lifted his leg over Hunk’s, settling on top of him with both his hands still pressed over his gut.
They stared at each other for a blink second. Surprise and relief mixed on Hunk’s flushed face, his mouth opening to speak, but Shiro didn’t wait to hear what he had to say. Because now he could feel what Hunk wanted; the hardness of his erection under Shiro’s weight told him everything he needed to know. He leaned forward without a word and kissed him, bracing himself on his arms to avoid putting too much pressure on Hunk’s stomach. God, it felt so immense, too bloated to give in an inch, and Shiro moaned into the kiss, heat rushing through him. Instinct drove him to grind his hips forward, his legs spread wide around Hunk’s girth to feel more of his gut, more of him.
He felt Hunk responding to the kiss, but his hands were pushing against Shiro’s shoulders, urging him to move back up. “Everything okay?” Shiro asked in a hushed voice, raising himself slightly; he wasn’t ready to give up on his position so soon.
“Ahh, mmh, yeah, yes.”
Hunk’s eyes shone bright, his tongue flicking out to wet his lips, but his brow was furrowed deep in obvious pain. He ran his palms up and down Shiro’s sides, feeling the tight V of his back while catching his breath. “Just gimme a minute,” he murmured, closing his eyes for a moment.
Shiro made a sound of agreement, swallowing his disappointment as he sat back up. But now that they were on the same page, there was no rush, and while Hunk recovered, he could take in the view in front of him unabashedly, without fear of judgement. And--he could do more than that, too.
He splayed his fingers on Hunk’s belly and ran them down to where his thighs cradled its sides. The yellow shirt was stretched tight over the bulge of it, not even showing the indentation of his navel; Shiro drummed it lightly, marveling the sound it made, and suddenly he couldn’t wait anymore--he needed to see.
He lifted his weight up to yank the hem free and peeled the shirt up as far as it went to reveal a stretch of brown skin and a shallow belly button. He bit on his lip as he tracked his fingers over the faded stretch marks around it, then grabbed onto the squishy part below. A shudder ran through him as he pinched harder to feel the thickness of it and said, “I can’t believe you could fit nine bowls of that stuff in here.”
Hunk inhaled sharply, drawing Shiro’s eyes back to his face. “You like that, don’t you?” he asked, voice gruff, his hand catching Shiro’s again and pressing it into his fat gut.
Shiro gasped; his answer come immediately even though he didn’t know if Hunk meant his fatness or the fact that he could eat so much in one sitting. “Yes.”
“Mm, well, I like it too.” Hunk released his hand and crossed his arms above his head with a grin, bucking his hips slightly to urge Shiro to continue. “Would do it again, even if it meant I’d be stuck in the common room all night.”
For a moment, Shiro’s mind flashed back to the moment he’d found Hunk, imagining him stuck on that couch again, helpless with the weight of his full gut pinning him into the seat. “You--” he started, but he wasn’t sure what he was going to say, the words scattered in his brain as he stared at the evidence of Hunk’s gluttony in front of him. “You are insatiable,” he said, trailing his hands over the fat flesh between his legs, feeling the need building up in the pit of his stomach.
His fingers slipped under Hunk’s shirt to palm the crest of his stomach, getting a sharp inhale from Hunk in response. His skin felt hot under his real hand, so hot he could almost imagine the sensation on his metal arm as well, and the feeling pushed him to continue his exploration further, rubbing down the round sides of Hunk’s gut.
It wasn’t enough, though. “I need this off,” he murmured, not lifting his gaze. He grabbed the hem and started tugging it up, trying to free it from under Hunk’s body.
A grunt escaped from Hunk’s lips as he squirmed around, lifting his body the best he could. Shiro could barely focus on the task at hand, his eyes riveted on the sight of that big full gut swaying from side to side; he wanted to touch every inch of the glowing skin that was slowly being revealed, too slowly--
Suddenly, Hunk gasped, his hands pressing into his gut. His eyes were closed, the pained frown back on his face as he kneaded his stomach.
“Are you okay?” Shiro asked, carefully caressing the sides of his belly.
“Yeah, yeah.” Hunk took a moment to open his eyes again, letting his breathing calm down before giving Shiro a bashful smile. “I think I need a little help,” he said, bringing their hands to meet, his fingers brushing against Shiro’s. “Can’t do this lying down.”
Shiro glanced down at their hands, but he knew what Hunk meant. “Of course,” he said, smiling, and maybe just a little bit excited at the thought of Hunk being so stuffed he couldn’t get up without help; he tried to shake off the feeling, but--Hunk didn’t seem to mind. He swallowed, then took a better hold on Hunk’s hands. “Ready?”
Hunk gave him a nod, and after counting to three, Shiro leaned back and pulled him up to a sitting position. “Jesus, fuck, that--” Hunk’s face immediately distorted into a grimace and he grabbed his belly again, his breath coming out in small puffs, but he didn’t block Shiro out this time. “God, I forgot how painful sitting up is when I’m this full,” he said with a laugh, looking up at Shiro. “Remind me again why I had that ninth bowl?”
“Because you love it,” Shiro said without a pause, and he didn’t realize it until after the words were out that that might be considered a weird thing to say. He saw Hunk’s eyes widen in surprised; they were so close now, so close that he only needed to lean in to catch Hunk’s lips in a kiss.
He gave himself into it, the warmth of Hunk’s mouth against his. The kiss was sweet, and tender, slow in a way that felt like it was happening in a completely different time. He could feel Hunk’s hands on his back, his waist, his touch filled with the same yearning that made Shiro’s hands move down to the plush side rolls that pushed over his tight waistband. He couldn’t hold himself back anymore, his pleasure coming out as a low moan that rumbled deep in his throat when he squeezed Hunk’s fat sides and pressed closer against that full belly sitting between them.
They broke apart and Shiro slipped his fingers under Hunk’s shirt, pulling it over his head and tossing it to the side. He took a moment to just look, painting the image into his memory for later inspection before framing his gut with his hands again. Sitting like this, it looked rounder than lying down, the skin stretched tight so that it looked almost shiny. Hunk shivered, leaning back against his hands without a word, letting Shiro have his moment.
“You can lie down if this is too much,” Shiro said softly, and Hunk didn’t need to be told twice--he lowered himself back on the bed ungraciously, careful not to disturb his stomach. Shiro bit on his lip, trying not to look too eager as he drank in the sight in front of him, but he needed more.
He trailed his fingers along the tight waistband that was digging into Hunk’s lower belly, pinching at the bulging flesh there. “These look uncomfortable,” he said, thumbing at the button that seemed almost ready to pop.
Hunk chuckled, his voice breathless when he answered, “A bit, yeah.” He reached out to touch Shiro’s arm, and though he couldn’t feel it, the gesture was as reassuring as his words. “You can open them, if you want to.”
Shiro hummed in reply; he kept toying with the button, trying to fit his fingers under the waistband to tug it lower, but as squishy as Hunk’s lower belly was, the pressure of his bloated gut was just too much.
“You need to, uh. Suck it in.”
“Roger that.”
Hunk sucked in his gut in as much as he could. It didn’t make that much of a difference, but with a concentrated effort, Shiro managed to unhook the button from its hole. Fortunately, the zipper took care of itself; as soon as Shiro let go, the two sides of the zipper separated with an audible zoom under the weight of Hunk’s expanding belly.
“Wow,” Shiro said, staring at the pudge that now spilled out freely from between the open fly. He pressed his hand on it, pinching the soft skin without thinking and giving it a jiggle.
Hunk jumped at the contact, the sound of his gasp making Shiro look up; his eyes were half-closed, shining darkly, but there was no doubt on his flushed face. “Keep going,” he said, licking his lips as if asking to be kissed again.
He nodded in a daze, but instead of continuing what he had been doing, he tugged up his own shirt and stripped it off his torso. He could hear Hunk starting to say something, but didn’t give him a chance to finish as he leaned over and splayed himself on top of him again.
This time, there were no obstructing layers of clothing between them, and Shiro wanted to moan just from the feeling of Hunk’s tightly stuffed gut against his abs. He knew he was being selfish, but he wanted to enjoy it just for a moment.
But Hunk wasn’t protesting; he was pawing at Shiro’s waist, his hips, trying to get them even closer. His head was tilted back, out of Shiro’s reach, so he bent down to kiss his neck instead. Hunk inhaled sharply when Shiro sucked a kiss into the soft spot under his jaw, moving lower, placing wet kisses across the warm skin until he got to Hunk’s chest.
Shiro shifted slightly to the side, bracing himself on one arm so that he could palm Hunk’s pecs with his real hand. He could feel the strong muscle underneath the fatty part, but it was the supple softness that excited him and made him want to press his mouth in for a taste. He jiggled the fat breast, teasing the nipple between his fingers before bowing down to find it between his lips.
“Shi--Shiro!”
He didn’t look up--couldn’t, because Hunk’s hand was suddenly on the back of his head, holding him firmly in place at his chest. It was so soft, and Shiro lost himself for a bit, sucking the fat flesh in his mouth until Hunk’s moans turned into stuttering gasps, his body wracked with pleasure.
He felt Hunk release his grip, and Shiro took the opportunity to reposition himself so that he was straddling Hunk’s thigh, then knelt down over the dome of his gut to press his cheek against it.
He closed his eyes.
It felt warm, hot even against his heated cheek, and he rubbed his face against the soft skin, craving the sensation with all his being. He could feel Hunk’s breathing lifting him and gave into the ebb and flow of it, a strange sense of calm coming over him as he listened to the churning, gurgling pops that came from within. All that food--Shiro felt a shiver go through him as he thought about the sheer amount of food that Hunk had managed to ingest, how proud he had been when he'd told him--
He turned his face into Hunk’s belly and nuzzled it, wanting to feel the fullness of it with all his senses. His lips parted to get a taste, fingers gaining purchase on Hunk’s squishy sides as he let loose, kissing, licking, mouthing against the warm skin.
Hunk gasped, grasping his shoulders, one hand finding the back of his neck again. Shiro felt him arching up as if he wanted more, more, and that neediness made him push harder, giving his everything to the cause.
He found his face buried in the soft blubber of Hunk’s belly, sucking hard kisses into the fat flesh. He delved his tongue into Hunk’s belly button, surprised at the shallowness of it until he realized it was only so because of how full he was; he licked around it and in again, greedy and tireless, until he found the wobbly flesh beneath it and buried his face in yet again, wanting to feel everything.
They were both breathing hard when Shiro finally came up for air, wiping spit off his chin as he sat back. He didn’t look up immediately, his gaze fixed on the red bruises and trails of dried up saliva now crisscrossing over Hunk’s middle, marking up the spots he’d most enjoyed.
“Hey.” Hunk’s hands appeared in his line of vision and caught his, dragging his attention back to the present. He glanced up and saw Hunk smirking at him; his eyes were glittering, round cheeks flushed red, not a trace of embarrassment on his features. “Can you get up for a bit?”
Shiro blinked, then nodded, rolling off to the side. He watched Hunk lift his hips and struggle off the rest of his clothes, anticipation building up in the pit of his gut as he saw Hunk’s thick cock spring free of his boxers. “Let me,” he said, already moving to pull the pants off his legs before settling between them.
Hunk sucked in a breath when Shiro palmed his erection and gave it a slow stroke. It felt almost painfully hard already, the head slick with precome, but he didn’t want to rush it too much so he took his time, pausing between strokes to squeeze the base between his fingers. His free hand had found its way back to Hunk’s gut, grasping at the soft flesh and making it wobble.
It suddenly struck him that this was the first time he was using his metal arm on someone else like this, and he paused, hesitating. “Is this okay?” he asked quietly, glancing up.
But Hunk didn’t seem to even register the source of Shiro’s worries. “Y-yes, yes, keep going,” he groaned, tilting his hips up to gain friction against Shiro’s hand and urging him with his whole body to continue.
Shiro tightened his grip, allowing himself a moment to watch the movement of Hunk’s fleshy body as he ground against his hand before picking up the pace again, this time with the aim to finish it.
And he did try--but it felt impossible to keep his focus on jerking Hunk off when there was that big bloated gut swaying right in front of him, when his fingers kept sinking into the jiggly flesh and dragging his attention back to it. Shiro bit on his lip, his body tensing up with yearning until he couldn’t take it anymore.
Hunk cried out when Shiro took his cock into his mouth and grabbed his belly with both hands, shaking it roughly, angling his head so that he could feel the fat flesh against his forehead and face. He could taste the salt of precome on his tongue, feel the tightness building up to a release, but most of all, he reveled in the soft, quivering plumpness against his skin.
He could feel Hunk drawing close, his breath catching as Shiro switched to using his hand again to suck at the fold of flesh by his hip, teasing the sensitive skin before going back to his cock. Maybe he said something--a name or a curse--but Shiro didn’t hear it; he was too lost in the pleasure he was getting from the act himself.
The end came abruptly--Hunk’s body went rigid for a moment, fingers clenched on Shiro’s shoulder like a vice before his hot seed suddenly spilled into Shiro’s mouth. His cock pulsed against Shiro’s tongue, telling him to slow down, and he let the come fill his mouth before pulling out and swallowing it.
“Jesus Christ, Shiro, that was...” Hunk made a vague gesture, trying to find his words, but nothing came out. Instead, he gave Shiro a sloppy grin, red spots of satisfaction glowing on his cheeks.
Shiro sat up, wiping his mouth on the back of his hand; he felt heated, the need to get off still burning in his veins, but at the same time, there was a deep sense of peace blooming inside him. “Yeah,” he said, voice muted as he trailed his fingers over Hunk’s soft lower belly.
“You want me to repay the favor?”
Shiro looked up, surprised. “You feeling up to it?”
“Er, probably not, not right away at least, but--” Hunk grimaced, looking sheepish. “--I don’t want to send you off with blue balls. And, uh. I’d like to, you know.” The color on his cheeks darkened and Shiro felt something warm flutter inside his chest.
Did Hunk like him?
“Mm, it’s okay. I can deal with it myself.” He moved to sit by Hunk’s side but kept his hand on his gut, caressing it slowly. “Wouldn’t want you to hurt yourself just to get me off.”
Hunk chuckled, turning slightly on his side to give Shiro better access. “Yeah, I do feel kinda queasy. And throwing up is such a waste of food, I hate when that happens.”
Shiro huffed, amused. Of course Hunk would feel worse about wasting food than throwing up in the middle of sex, that’s just who he was. He brought his palm down to where Hunk’s belly curved up from his hip and squeezed the flesh, giving it a jiggle; Hunk made a sound, but didn’t say anything, leaving Shiro to enjoy himself in quiet.
“You’re still so full,” Shiro said as he smoothed his hand over the top of Hunk’s stomach. He thought about everything Hunk had told him about his experiments, all the testing and tasting, his mind finally circling back to the nine bowls tonight. How much more had Hunk been eating lately? It had to be a lot to stretch out his stomach like this, but--somehow, it didn’t seem like he had gained all that much weight. Shiro felt a stirring at the pit of his gut; he bit his lip to hold back a smile, then said, “As the team leader, I should probably be telling you to take it easy on the goo in the future, or you really won’t fit in your suit soon...”
At that, Hunk burst out laughing. “Oh, you don’t need to worry about that. I don’t think I’ll be able to top this record any time soon. And besides, the goo ain’t making me fat, if that’s what you’re thinking.”
Shiro stopped what he was doing, and looked up. “It’s... not?”
Hunk was grinning at him widely, looking positively impish when he said, “Oh, no. Not at all.” He lowered his hands to his gut and rubbed it, still smirking at Shiro’s confusion. “That’s the beauty of space food, it doesn’t quite work like you’d expect it to. I’d say I’m pretty much the same size as I was when we left the Earth, just better at filling up.”
Shiro stared at him. His mind was suddenly full of questions, ideas, things that made the heat in his gut flare up like a wildfire. But before he could say anything, Hunk was talking again.
“Of course, there is food that will do the opposite as well. I mean, make you put on weight and fast.”
“Uh,” was all that Shiro could say. He looked back to where his hands lay on top of Hunk’s belly and imagined it rising higher, spilling wider, growing and growing until there was no way Hunk could get that space suit on his massive frame any more.
He could barely keep his face straight as the image took form in his mind’s eye--or maybe not at all, as Hunk’s voice was full of teasing when he said, “You want me to keep talking?”
“Later,” Shiro said. “I need to, ah. Take care of something.”
He quickly repositioned himself, one hand on Hunk’s belly and the other one reaching for the waistband of his pants.
He would definitely ask more questions later.
