The Shape of You

Summary:

Prompt - Never prompted before but been loving your recent fics, so another prompt for you if you so wish, though feel free to ignore! Something like Hotel, buffet table, Mac subtly manipulating Dennis to eat and gain weight, vulnerable insecure Dennis, some lie from mac about how hotel calories don't count, realization of only one bed, massage, room service, more manipulation, Dennis actually starting to enjoy himself a little, gaining more weight, being good for Mac as he feeds him, dash of spice 😉.

Notes:

Okay, so I try to stay within the realm of possibility even though I know this is fanfic. Well, let me tell you all that it's amazing what you find out when you do research for shit. So, even though I wanted to get weird with it, I will say that the amount of weight Dennis gains is actually possible in real life. (The person to hold the record gained 60 pounds in a week for 6 weeks straight, to put it in perspective.)

Oh! And yes, weight gain (appetite stimulants) are real and you can buy them on Amazon or in a health store.

(See the end of the work for more notes.)

Work Text:

Day 1

“I thought you said this was a health and wellness resort,” Dennis said as he peered around the hotel. “It looks like a regular resort to me.” He folded his arms across his chest, and Mac glanced over at him, gaze dropping to the curve of his stomach, only made more noticeable by the way he was positioned. Dennis always stood with his lower back tilted slightly forward, and with his recent weight gain (that he was trying desperately to hide with billowy shirts and oversized button ups), his round belly stood out even through the loose cotton.

“Well, just because it looks like a plain old hotel doesn’t mean shit,” Mac countered. “Looks can be deceiving,” he added for good measure, and Dennis shrugged as he peered around.

“I mean, it’s not like I really care all that much or anything. We’re not paying for it,” he scoffed then nudged Mac with his elbow.

Mac grinned. Dennis was right about that much. They weren’t paying for it, Frank was (unknowingly) but that didn’t matter in the grand scheme of things. No, what mattered was Mac had gotten Dennis alone like he’d wanted, and the rest…Mac couldn’t wait for the rest.

His and Dennis’ relationship had been rocky as of late. Mac wasn’t sure what happened or what changed, but Dennis was constantly belittling him or berating him for the littlest of things. Mac couldn’t seem to do anything right, and frankly, Mac had grown sick of it.

He decided that it was time to show Dennis who the real boss was, and what better way to do that was through means of manipulation via Dennis’ weight.

It was the one thing Dennis held above everything else – his looks, and Mac was going to ensure that Dennis understood his place once he was finished with him (or rather, he was just getting started).

For the last two months, Mac had started Dennis on a new vitamin routine that he promised would make Dennis ‘more healthy than he’s ever been’.

Dennis had fallen for it, hook, line and sinker.

Mac had plied him with one pill, three times a day before he ate, and Mac stressed that it was important that he ate, otherwise, they wouldn’t work.

Dennis had been wary at first, but the second his face started to glow, he went all in (not realizing that the reason for the sudden change was the fact that he was no longer gaunt). He steadily began to gain weight (as those pills were no vitamins) and before long, he added almost forty pounds to his frame.

Watching him fill out his clothes and then some did something to Mac, ignited a desire deep within him that he hadn’t realized was there, and he knew all he wanted was to see Dennis grow even larger.

Naturally, Dennis had caught onto the fact that he wasn’t exactly a lithe one hundred and sixty pounds anymore and started to complain about his new fuller figure so Mac had claimed he won an all expenses paid, two-week vacation to a health and wellness spa in upper state New York. (It was in fact, not a health and wellness spa.)

“Well, I don’t know about you but I’m starving,” Mac emphasized the word, knitting his eyebrows together to appear more genuine, and Dennis glanced over at him, lips twisted to the side. “Why don’t we check out their lunch selections?” he suggested, then led the way to the dining area.

Laid out before them was table after table of food, fancier fare as well as simpler dishes like fried chicken and mashed potatoes, and Mac’s heartbeat began to quicken. He wondered how much of it he could get Dennis to eat. He’d been watching videos on YouTube as of late, people that would stuff their faces with twenty to thirty thousand calories in a day and gain twenty pounds in the process. It was insane (yet hot), and as he gazed at the other man, he couldn’t wait to test his theory out on him.

Mac began to fill his plate and watched with despair as Dennis picked up a lousy fruit bowl and a cup of coffee.

Now that would just not do.

“Don’t forget your vitamins,” Mac reminded him as they sat down at a table and he fished two large white capsules out of his pocket.

“Two?” Dennis asked, not waiting for a reason from Mac before he washed them down with his coffee. “You know, ever since I’ve been taking these, I’ve felt different,” he admitted, and Mac feigned a look of interest as be bit into a crisp slice of bacon.

“How so?” he asked, and Dennis shrugged then took a tentative nibble out of a strawberry.

“I don’t know,” the other man replied as he gazed hungrily at Mac’s full plate. “Just…different.”

“Huh, weird,” Mac muttered distractedly then moaned. “Oh man, this low-calorie bacon is delicious. I don’t how they do it but it’s amazing.”

“What do you mean low calorie?” Dennis asked as he once again glanced over at his plate, and Mac watched him swallow thickly, then lick his lips.

“Oh, it’s some special recipe they use with all the food. Every plate only has like ten calories or less. It’s like a way to trick yourself into eating healthy. Who knew?” Mac raised both arms then took a large bite out of the sandwich he'd picked up.

“Wait, you’re saying that everything here is all low calorie?” Dennis questioned as he waved a hand around the buffet.

“Yep,” Mac popped his ‘p’ in response, internally delighting in the interest that now piqued across Dennis’ fuller face.

“Everything,” he repeated, and Mac nodded.

“Every. Single. Thing. It’s some secret weight loss trick. This deep-fried chicken sandwich covered in gravy and cheese? Ten calories. That entire pizza over there?” he continued as he nodded towards a pepperoni that was laying on a large platter. “Ten calories. That’s it.”

“Huh. Well, that’s interesting,” Dennis murmured as he peered around. “I’ll, uh, be right back,” he announced and got up.

Mac snickered to himself as he watched Dennis fill up two plates worth of different dishes from the pizza he’d mentioned before to some expensive looking shit that looked like it came straight from some type of cooking magazine.

Dennis sat back down, removed a napkin from its ring then placed it onto his lap and began to eat. It didn’t take long for the effects of the ‘vitamins’ to kick in, and the two plates he’d filled up were gone in no time.

Ever one to be of service, Mac glanced over at the other man then posed an offer. “You, uh, want more?” he questioned casually, and seeing that Dennis had put on a mask of indifference himself, replying with a half shrug, Mac took that as his cue to get him a refill. He loaded up the plates with food that he knew had the highest sodium content (which was great for causing water retention and would enable Dennis to gain weight more quickly and efficiently) as well as items that were loaded with sugar (which would turn into fat; Mac had been doing his homework).

Dennis’ eyes widened when he saw everything Mac had brought him back, lips parting in shock before he licked them nervously. “That’s, uh, quite a bit you’ve got there.”

Mac hummed. “I mean, you kind of got to take advantage of the fact that it’s so low calorie, you know,” he remarked with a wave of his hand. “Back home, it’d be different, but right now… When in Rome, am I right?”

The other man took a deep breath, one hand absentmindedly tugging at the waistband (that had already been tight) and scratched the back of his neck. “I mean, yeah, I guess – I guess you’re right. It’s not every day that – that one gets an opportunity such as this,” Dennis agreed, and one half of Mac’s mouth lifted imperceptibly.

“Exactly,” Mac nodded, then proceeded to observe his best friend out of the corner of his eye as he moved hesitantly at first before he gave in and continued to stuff himself.

The casual red and blue striped button up Dennis wore had been loose before, but four plates later, gaps were starting to form between the sides of the material, exposing patches of the smooth skin that lay underneath it.

“That’s all your going to have?” Mac noted offhandedly when Dennis sat back and began to massage the stomach that was now being hugged by the cotton fabric.

“I think I’ve had enough,” Dennis replied, then pulled at his waistband again before gripping the ends of his shirt and trying to move them as far away from his swollen belly as he could.

“If you say so,” Mac muttered with a nonchalant sigh, palm encasing his chin as he rested his arm on the table and peered around the room. He knew how badly Dennis craved attention, and when he wasn’t getting it, wasn’t the center of Mac’s world, well, that upset the man more than anything else, and if Mac looked like he was growing bored, surely, Dennis had to entertain him.

“You know, on second thought, would you, uh, would you get me some of the red velvet cake, and maybe a touch of vanilla ice cream too?” he added, and Mac covered his grin with his fingers as he stood then forced his mouth back into a thin line.

“Sure,” he answered and got up, eyes teeming with delight as he went over to the dessert table and loaded up two more plates – one with a piece of cake that took up the entire circumference of the platter then another that had a large bowl of vanilla bean and caramel ice cream on it. He set both down in front of Dennis, eyes closing briefly when he heard the whimper leave Dennis’ lips at the sight before him.

“You’re not having any?” Dennis questioned with an anxious note in his tone, and Mac shook his head.

“No, I still haven’t figured out quite what I want yet. By all means though, go ahead,” he flicked his wrist towards what had to have been at least two thousand calories of sugar if not more then took a sip of his water.

Since he’d upped the dosage on Dennis’ vitamin regime, the second wave of hunger was sure to kick in at any moment, and sure enough, the reluctance that Dennis initially held went away when he was a quarter of the way through the cake. The fork rose and lifted to his frosting covered mouth in quicker succession and before long, both the plate and bowl were empty.

“How am I still hungry?” he heard Dennis mutter under his breath, and it took every ounce of self-control Mac had in his body to not shake his fists in exhilaration at the amount of food Dennis had already consumed. His poor shirt was starting to strain, and yet, Mac wasn’t done with him by a long shot. (After all, the day was just getting started.)

“I can get you something else if you like. I’m pretty sure I saw some crème brulee –”

“Crème brulee?” Dennis cut him off, and Mac nodded, faux innocence in every movement.

“Yeah, did you want some?” He kept his voice light, just airy enough to not sound forceful but helpful, and Dennis swallowed thickly before he shrugged.

“When in Rome,” he echoed Mac’s earlier words, and like the polite little servient angel he was, Mac got up, retrieved two large bowls of Dennis’ favorite after meal snack then placed it before him on the table. He moaned the moment the spoon filled with the sugary delicacy passed his lips, and Mac watched with bated breath as Dennis knocked back both bowls then finally sat back in his chair. “I think I need a nap,” he mumbled, eye lashes fluttering across his cheeks.

“Well, this is a health and wellness spa, and getting the proper amount of sleep is important to one’s health, is it not?” Mac asked, and Dennis nodded, double chin forming at the gesture.

Mac added up the numbers in his head as he helped Dennis stand (he had eaten just over ten thousand calories in one sitting), a whimper of his own escaping his throat as his gaze fell to Dennis’ swollen belly. The shirt was so tight that every inch of skin below his belly button was on full display, and Mac was thankful that he’d worn a pair of his looser pants as his dick was now fully erect. “Here,” he said as he wrapped both hands around one of Dennis’ soft biceps. “Let’s get you upstairs so can rest for a while.”

“Sounds like a plan,” Dennis murmured, and allowed Mac to corral him past numerous pairs of raised brows to the awaiting elevator. “My God, I’m so full,” he mumbled breathlessly once they were almost to their room. “I don’t think I’ve ever eaten that much in my life.”

“You’re not done yet,” the retort immediately left Mac’s tongue, then he shook his head at his misstep.

“What did you say?” Dennis asked, looking over at him dazedly.

“I said, it’s time for some rest,” Mac lied with a grin, and Dennis nodded then moaned as he held his bloated belly. “Here we go,” he said as he opened the door to their room with the electronic key card then assisted Dennis over to the bed.

As soon as he sat down, all the buttons below his pecs snapped off the shirt to reveal his overly stuffed belly along with the pale skin that was peppered with a light dusting of hair.

“Oh my God, did I just ruin my shirt?” Dennis gaped down at himself, and Mac’s reaction was slow, still entranced with how big Dennis had gotten.

“What? Uh, no, it’s fine, the buttons were just loose,” he lied and helped Dennis lay back.

“They felt pretty tight to me,” Dennis countered as he tried to tug at the ends, but the shirt would no longer close. “Jesus Christ I’m fat!” he exclaimed as he looked down at himself.

“You’re not fat,” Mac shook his head, then swatted his hands away from his bared stomach. “You’re just full of nutrients, and that’s a good thing, remember?”

“Just full of nutrients,” Dennis mirrored, a horrified expression still capturing his chubby face.

“Exactly. Now close your eyes, and relax and let me take care of you,” Mac told him, then started to massage his belly. “Jesus, your pants are tight. Let me just handle that real quick,” he muttered and grimaced as he attempted to undo Dennis’ jeans, finally releasing him from their prison after three tries.

“God, that feels so much better,” Dennis breathed the words out, brow lowering and another moan parting his lips when Mac started to massage his round stomach. “That feels good too,” he said that words lowly as he teetered on the edge of unconsciousness.

Mac reveled at how high Dennis’ belly curved upwards, how full it was. He dug his fingertips into the large mound of flesh, amazed at how much weight Dennis had packed on in such a short amount of time. He knew his pre-weight was right around two hundred pounds, and he was determined to get that number as high as possible before they left.

The scent of coq au vin awoke Dennis from his sleep, and he cracked open his eyes then peered around the room.

Mac was sitting at the foot of the king-sized bed (the only bed in the room), elbows resting on his knees as he watched what appeared to be a video of some type of eating contest.

“What are you watching?” Dennis asked as he sat up, then rubbed the sleep out of his eyes.

“Huh? Oh, no-nothing,” Mac stammered as he hurriedly flipped the channel then turned to look at him. “You’re just in time,” he grinned, and Dennis looked over at him, eyebrow arched in confusion.

“Just in time for what?” he asked, then his gaze drifted to the three portable food trays that were placed next to the bed, loaded with fresh dishes that steam wafted off of.

“Dinner,” Mac smiled, teeth peeking through his lips as he set the remote down and got up. “They had so much to choose from, and since I think it’s been a while since you got a good night’s sleep, I went ahead and just got one of everything. You know, so you could sample it all,” he said as he gestured towards the large array of food.

“I can’t eat all that,” the words flew out of Dennis’ mouth as he gawked at the monumental number of dishes. “That’s too much! Way too much.”

“Dennis, Dennis,” Mac sat down next to him and patted his back. “Don’t you remember? It’s all super low calorie. You can eat as much of it as you want, and you won’t gain a pound. In fact, you’ll probably lose weight.”

“I – I will?” Dennis questioned uncertainly, and Mac nodded, fingers sliding over the gray cotton.

“Yeah,” Mac nodded eagerly. “That’s what this place is for after all, right?”

“Uh, yeah, right,” Dennis muttered, then glanced down at himself. Shame flooded over him when he saw how far his stomach expanded outward onto his lap, the shirt that he didn’t remember changing into tight on his larger frame. “I’ve got to use the bathroom,” he said, and got up, fingers immediately tugging down his shirt as he disappeared into the bathroom. He flipped the light on once the door was closed and stared at his reflection in the mirror.

What the hell had happened to him?

He wasn’t blind, wasn’t stupid. He’d been putting on weight for a while, unable to fill the seemingly bottomless pit his stomach had become, but now – it was like he’d been a man possessed earlier. No matter how much he ate, it wasn’t enough. He turned to the side, a whimper leaving his lips as he glared at the stomach that was bigger than a pregnant woman’s. He wasn’t just chubby, he was fat, there was no denying that fact now.

His belly was round and large, larger than it had ever been before in his life. He placed his palm on the center of it and jiggled it, watched in horror as it bounced underneath his touch. There was no way in hell he could eat anymore, even if it was low in calorie. He needed to fucking lose this shit, and fast.

He tugged the shirt back down then splashed water onto his face, onto his doughy cheeks.

Fuck!

The urge to cry struck him, but he tamped it down, not wanting to embarrass himself further. It was bad enough Mac looked like a fucking body builder now. What a fucking pair they were. Now, Dennis would be labeled as ‘the fat one’ wherever they went.

“You okay in there?” Mac’s voice drifted from the other side of the door, and Dennis jumped then swiftly shut off the water.

“I’m fine!” he replied hotly, then dried his face off but not before giving it a scrutinizing glower. His cheeks were getting full too, and goddammit, there was a double chin! Nope, Mac could eat all of that shit himself. Maybe he should look for the gym. As he glanced down at himself, clad in hip-hugging sweatpants and a tee that was small two sizes ago, he changed his mind. There was no way in hell he could go out in public looking like that.

“The food’s getting –” Dennis flung the door open, and Mac’s open mouth closed before he finished his sentence. “Cold.”

“I don’t care. I’m not hungry,” Dennis stated, brow lowered as he sat back down on the bed and folded his arms over himself.

“But you haven’t eaten since lunch and the last thing you want is to ruin your metabolism,” Mac told him, and the creases in Dennis’ forehead deepened.

“How would I do that?” he asked, gaze darting from the bed up to Mac’s face then back down again.

“Oh, it’s a simple nutritional fact,” Mac replied with a flick of his wrist. “The longer you go without eating, the worse your metabolism gets, and the quicker you gain weight. See, the more you eat, the faster it gets which actually helps you lose weight in the long run.”

Dennis sat there for a moment, going over Mac’s words in his head. He’d never really read all that much about metabolism as the subject had sounded rather boring, and Mac, for once, sounded like he knew what he was talking about. The food did smell enticing, and why waste a perfectly good coq au vin? “Fine, I’ll have a little but there’s no way in hell I’m eating all of that. You’re having some too, right?”

“Well, yeah,” Mac nodded. “I haven’t eaten since you have. Oh,” he added as he got up, went over to his bag then removed the bottle of vitamins he’d been giving Dennis. “Don’t want to forget these,” he said, then handed them to Dennis as well as a cold beer.

Dennis gave them a passing glance before he tipped his head back and popped then into his mouth, then washed them down with the microbrew that tasted fucking amazing. “Holy shit,” he gaped. “Is this local?” he asked as he looked at the label, and Mac nodded.

“Yep, and,” he grinned as he elongated the word, “It’s lite beer too! Can you believe it? I got us a whole case of the stuff.”

Two hours later, Dennis found himself in the center of the bed, two pillows resting behind his back as he held his stomach. His chest heaved as he struggled to breathe, and he wondered if it was possible for a human to actually burst from eating too much. His gaze drifted over to all the empty plates that now littered the trays that had been full. Between him and Mac, they’d eaten everything. Every. Fucking. Thing. (He didn’t realize that it had mostly been him, the other man only ingesting a single plate of food.)

“You doing okay over there?” Mac asked as he came out of the bathroom, and all Dennis could do was moan in response.

“So full,” he muttered, and instead of flinching away from Mac’s touch as he’d been doing a lot of lately, he closed his eyes as the man started to massage his overstuffed belly. “God, that feels good,” he breathed the words out, then took the crisp, cold can of beer Mac handed him. He popped the top then took a sip, letting a loud burp as Mac’s fingers dug into a particularly dense spot. “Are you sure this is lite?” Dennis asked as he turned the can around and looked at the label, and Mac scoffed as he swiftly twisted the cool aluminum back into its original position.

“I don’t think they’d lie to me about that,” he replied, and Dennis hummed then took another long drink from the can.

Suddenly, there was a knock on the door, and Dennis’ brow furrowed as he looked over at Mac. “Who’s that?” he asked, and Mac’s bottom lip tucked itself between his teeth as he rose to his feet, murmured something to someone, and then pushed another cart next to the bed.

“I just ordered a little dessert is all,” he shrugged then removed the metal lid that had been covering not one but five different sugary treats.

“Christ, Mac, are you trying to kill me?” Dennis quipped then finished off his beer.

“No, but I just thought, you know, you should enjoy yourself a little bit,” he replied, voice dipping in tenor. He climbed back onto the bed, one hand sliding along the lower part of Dennis’ stomach before he rested it on top of the large bump, directly over his belly button. “You do want to enjoy yourself, don’t you?” For the first time since they’d been there, Dennis became aroused, dick twitching underneath his belly as Mac began to twirl his fingers lightly over his skin.

They’d been dancing back and forth with one another for a while, one always hot (Mac) while the other was always cold (Dennis), but now, especially with the way Mac was currently looking at him, those honey-colored eyes full of warmth and dare Dennis think, seduction, he found himself under Mac’s spell. Of course, Dennis wanted to enjoy himself. Why wouldn’t he?”

“Well, yeah, I do, but –”

“So, enjoy it,” Mac interrupted him, left index finger and thumb rising to his lips as they slipped a capsule into his mouth.

Dennis swallowed it on instinct, unable to take his eyes off Mac’s. Without a word, he gave Mac silent permission, and the second it became apparent, Mac’s eyes widened before he swiftly picked up a plate that had a tres leche cake on it along with a fork then straddled Dennis’ hips.

He cut off a piece of the sweet decadent treat then held it up to Dennis’ lips, and Dennis quickly opened his mouth, allowing Mac entry.

The fullness that encompassed his stomach began to dissipate with every bite, and before long, the emptiness that had consumed him for months on end returned, and Dennis longed to fill it once more.

He inhaled the cake, followed it with a dark chocolate brownie drizzled with raspberry syrup and sweet cream, then moved onto a strawberry cheesecake that was equal parts tart as it was sweet. The fullness returned once he took the last bite of the banana bread pudding that was his fourth choice. It was once again growing harder and harder to inflate his lungs, but his mouth watered upon seeing the triple chocolate soufflé Mac now had in his hands. He moaned when the velvety sweetness hit his tongue, and even though he was so stuffed he could no longer move, he allowed Mac to feed him the entire thing until there wasn’t even a smudge of chocolate left on the plate.

Mac put the empty plate away then lay on his side next to Dennis, a dreamy grin on his face. “How are you feeling?” he asked as he started to massage the side of his belly, the belly that was now bare as the t-shirt he’d been wearing had rolled up to reveal it.

“Tired,” Dennis mumbled, and he was. He didn’t understand how one could get exhausted from simply eating but his eyelids were starting to grow heavy, as heavy as his stomach now was. It was comforting though, in a way, comforting to be so full, so warm…

He could get used to this…

Day 5

Mac couldn’t stop smiling. He was a fucking genius. No, he was smarter than a genius, whatever word that was.

His plan had gone smashingly, better than that actually.

The night before, he’d lured Dennis onto the scale he’d brought so he could chart the other man’s progress as it was more than apparent Dennis had gained quite a bit of weight since their arrival, and boy, he hadn’t been wrong.

In less than a week, Dennis had already put on over thirty pounds, almost all of it settling on his stomach, and Mac couldn’t take his eyes off him.

Now, they hadn’t banged yet, but they had kissed twice, and Mac was positive that tonight would be the night. He was sure of it.

Trying to be as inconspicuous as possible, he watched Dennis change out of the corner of his eye. Since Mac had been hopeful, he’d ensured that he brought along some larger clothes for Dennis, just to be on the safe side (he’d already outgrown the outfit he wore on their first day there), but even those were getting harder for the man to button.

Dennis grimaced as he clasped his jeans together, unable to suck in the large gut that now hid his waistband. He slipped on a black sweater that clung to the round shape of his belly, only emphasizing its size.

“Ready for some breakfast? They have pancakes,” Mac waggled his eyebrows as he stood and Dennis glanced at himself in the mirror that sat next to the bed, brow lowering as he studied himself. Seeing the doubt that was starting to form, Mac pulled him away from it and grinned. “And those fancy German waffles that you like so much,” he added, and hopefulness soon raised Dennis’ eyebrows.

“The ones with the bits of truffle in them?” he asked, and Mac nodded then hurriedly ushered Dennis downstairs to the dining area.

“You have a seat, and I’ll be right back,” Mac told him, grabbing him a cup of coffee first before he loaded up three plates full of food and returned to the table. He couldn’t help but notice how far back Dennis had to sit from the table to prevent his stomach from hitting it. “Oh, just one second,” Mac stopped him before he could start eating, and handed him three pills.

“Can’t forget those,” Dennis smiled then took all three at the same time before he started to shovel food into his mouth.

Mac took his time with his plate, sampling his omelet and oatmeal as Dennis ate entire pancakes in just two bites. He glanced at him, throwing a soft smile his way as he imagined what he had planned for later that night. (There were zipties upstairs, just begging to be used.)

As had become customary, the second Dennis put his fork down, Mac picked up his empty plates and refilled them. This went on three more times before Dennis finally sat back and held the belly that looked like it could rip the sweater in half at any moment.

They held the same routine day after day – breakfast, followed by a nap, then lunch, another nap, and finally, dinner. (They hadn’t left the hotel once.)

“You’re looking pretty sleepy there,” Mac joked, and Dennis nodded, a breath whooshing out between his lips as he tried to stand but collapsed right back down to the chair. “Here, let me help,” Mac offered and extended his hand out which Dennis readily held.

He swayed dangerously when he made it to his feet, but Mac caught him before he could go back down.

“I’ve got you,” Mac told him, sliding one hand around his love handles as he took him back to their room.

“M’ so sleepy,” Dennis murmured as Mac helped him onto the bed, the mattress squeaking underneath his weight.

“Get some rest. I’ll wake you up when it’s time for lunch,” Mac promised, and Dennis nodded before his chest started to rise and fall slowly.

Even though Dennis was asleep, Mac still decided to massage his belly, knowing full well it would help Dennis rest more better. Hiking up the sweater had risen the second Dennis got up out of his chair, Mac peeled the black wool back and started to knead the softness that had previously been resting underneath it.

Dennis was so fucking hot like this, Mac thought as he dug his fingertips into his stomach, relieving the pressure that had built as Dennis ate. His thighs had gotten thicker, his ass plusher and rounder, there was a layer of fat that now clung to his neck and chin, but his stomach had taken the brunt of his weight, and it was fucking marvelously round.

Mac continued his ministrations until his hands started to ache, but even after, he sat there and stared longingly at the man who was slowly beginning to give into all the temptations Mac laid out before him.

He’d cried the second and third days over how large he was getting, but Mac knew how to soothe him, knew how to dry his tears then feed him to the point of near delirium. On the fourth day, Dennis’ insecurities seemed to be all but forgotten, and he’d become more pliant and willing to do whatever Mac asked.

As though he’d finally realized that it was okay to not be skin and bones (which if it were up to Mac, Dennis would never see another one of his bones protruding underneath his skin as long as he lived).

Around noon, Dennis started to wake up and Mac had room service ready and waiting for him.

Dennis changed into more comfortable clothes (sweats that were now starting to get rather tight and a short-sleeved tee that still had a little bit of give to it) since it was just the two of them and sat back on the bed, then allowed Mac to feed him as he’d been doing since that first night.

The amount he’d been able to consume had also grown, almost doubling in volume. Mac had to admit, he was amazed at how much Dennis was able to put away, but also, how willing he’d become.

Twelve thousand calories later, Dennis panted as he held his stomach. “Fuck,” he breathed the word out, and Mac dabbed at the corner of his lips, removing the sauce that had built up there.

“Somebody was hungry,” he teased then started to rub Dennis’ belly again.

“When am I not,” Dennis muttered, and Mac chuckled. “Fuck,” he repeated as he looked down at himself. “If I keep going like this, you’ll have to roll me out of here.”

“We don’t have that much time,” Mac sighed, and Dennis glanced over at him.

“Huh?” he asked, and Mac shook his head.

“Nothing,” he grinned with a shake of his head, giddiness running through him at the fact that they still had nine days left to go. He wondered how far he truly could push Dennis…

Dennis’ mouth watered before he even opened his eyes. The heavenly mix of garlic, rosemary, and herbs hit him, and he cracked open an eye, glancing around the room before his gaze landed on his bare belly. “Jesus Christ,” he muttered to himself, the dread he’d originally experienced at his weight gain transforming into shock. He was fucking huge, and yet, as much as he wanted to hate himself for it, as much as he wanted to berate himself for succumbing to the weakness of eating, it was starting to bother him less and less with each day that went by.

Being able to eat and enjoy what passed between his lips was shockingly gratifying, and as loathe as he was to admit, it was nice to be able to eat and not worry about the consequences.

Now, perhaps that would change when they were back home and Dee was calling him Porky the Pig, but right now, with it being just him and Mac, things were different.

It was…nice.

“Hey there big boy,” Mac teased as he came out of the bathroom, and a small smile perked up Dennis’ lips at his appearance. It was also quite nice to have Mac taking care of him too. He didn’t need to worry about anything.

“Hey,” Dennis smiled, and it was at that moment as he went to reach out towards Mac that he noticed the predicament that he was in.

Mac had ziptied his wrists to the bedpost, leaving him unable to move.

His cock immediately swelled, and he whimpered as Mac straddled his waist, devious grin set upon his lips.

“I wanted to try something a little different tonight,” he said, and Dennis wasn’t about to fight him on it.

Something deep inside his brain gave way, and all he wanted was for Mac to feed him until he couldn’t move then fuck him within an inch of his life. He’d never been so turned on.

“You ready?” Mac asked, tongue peeking out between his lips and Dennis nodded, ignoring the way the skin underneath his chin formed not one but two rolls at the gesture. Down the hatch went the three pre-meal capsules that were hurriedly followed by plate after plate of calorie and sodium rich foods, and at this point, Dennis knew Mac was full of shit, but he didn’t care anymore, too enchanted by the happiness he’d suddenly been granted.

Even when he started to struggle for air, even when he started to tug at his confines because he was positive his stomach was going to explode, he kept going, kept pushing himself because he liked it. At first, he hated that he liked it so much, but now, there was something thrilling about upping his limitations, about going further than he had before.

“Goddamn,” Mac muttered, astonished as Dennis put away the last bite of food. “Goddamn.” He slid his hand over the slope of Dennis’ engorged belly, and Dennis moaned at his touch.

He was unfathomably full. Nothing compared to the sensation that enveloped his stomach. It was heavier than heavy, as though it were made out of lead. He peered down at it, too blissed out to understand how large it had become. “Want you to fuck me,” he murmured, and gazed up at Mac through half-lidded eyes, watched as his pupils consumed his irises.

“You what?” Mac’s voice was low, deep and overrun with wonderment.

“Want you to fuck me,” Dennis repeated breathlessly as his arms hung uselessly above his head. “Please,” he added, and grinned when Mac whimpered.

“You’re sure about that?” Mac asked, and before Dennis could respond, Mac cut him off. “Okay,” he said, answering his own question then nodded.

Even though sleep was begging him to lose himself to its beautifully tender clutches, Dennis fought it off, held out so he would know what it was like to be completely and utterly full.

“Fuck, fuck, fuck,” Mac chanted as he quickly made all of his clothes (and what was left of Dennis’) disappear. Seeing the impatience that all but encompassed the other man, Dennis allowed him to work him open quicker than what he would’ve preferred, but it still didn’t stop the pleasure that began to overwhelm him as Mac added a second then third finger in quick progression. “Fuck, you are so goddamned beautiful,” Mac whispered as he placed one hand over Dennis’ very distended belly, even his touch making Dennis’ shoulders curl forward.

His fingers dove in and out, stretching and stretching until Dennis thought he was going to erupt. The burn flared up throughout his lower belly and caused the pressure he was already experiencing to double. He keened underneath Mac, low whines pushing past his lips as Mac quickened his pace until he replaced his fingers with his cock, and Dennis thought in that moment he was going to die.

He cried out as Mac slid inside him, tears already forming trails down his cheeks as Mac didn’t move but kept steady, moaning himself as he filled Dennis to the hilt. “Oh fuck!” Dennis cursed as Mac draped his thick calves over his shoulders and began to thrust in and out of him.

“Jesus Christ, Dennis!” he choked the words out as he picked up a steady rhythm, one that made Dennis’ belly jiggle as he repeatedly slammed into him. “Fuck, oh, fuck, oh fuck!”

The pressure was immense and more intense than Dennis had ever endured before. Having as much food that was currently sitting in his stomach coupled with the size of Mac’s dick occupying what little space was left over drove him into a state of euphoria. There was no other way to describe it.

Mac’s hands roamed his expansive belly before they settled on his plush sides, fingers grasping the fat that now lay dormant underneath his skin as he adjusted his position then started to plow into Dennis, striking his sweet spot until Dennis came violent and hard, vision temporarily out of order as he painted his underbelly with the creamy white substance.

“Oh my God, that was so hot!” Mac praised him breathlessly as he clutched his love handles harder and began to rail him, pace becoming erratic until he too finally came. Like the debauched heathen that he was, Mac leaned over once he pulled out and began to lazily lick Dennis’ cum.

Dennis began to sob as Mac’s tongue dragged along his skin, over and over until he was clean, but then the man decided to go one step further, nestling himself in between Dennis’ thighs as he pitched his lower half upward (painfully so as Dennis was still completely stuffed), and started to lick the ring of muscle Mac had fucked.

Somehow, he came one last time before he passed back out, fucked beyond belief.

Day 13

“Goddamn,” Dennis moaned as Mac rode his dick then shoved a forkful of strawberry rhubarb pie past his lips.

“You like that?” Mac teased huskily as he braced himself on Dennis’ belly, fingers splaying across the mound of fat as he scooped up another calorie laden bite and placed it onto Dennis’ tongue.

“Yes,” Dennis breathed the word out, and Mac grinned then continued to impale himself on Dennis’ cock as he fed him the final piece of the baked good. Once the tin was empty, he poked Dennis in his gut, finger sinking into the first knuckle.

“Looks like you’ve still got some room in there,” he taunted as he leaned down and whispered the words in Dennis’ ear, smiling as Dennis’ nails dug into his back.

“Maybe, maybe a little,” Dennis admitted breathlessly, and Mac reached over and removed the triple chocolate truffle ice cream from the now empty tray then proceeded to spoon feed Dennis as he bounced on his dick.

“You’re so goddamned gorgeous like this Dennis. So fucking gorgeous. Never in a million years,” Mac muttered as he continued to fill Dennis’ mouth the second it was empty.

Their routine had changed in the days since he’d first fucked Dennis. Dennis went from napping in between meals to fucking (while still getting a nap in every now and then) and had gained an additional thirty pounds. It was unbelievable how the weight attached itself to him so fast, but Mac was pretty sure it was mostly due to the fact that he rarely ever left the bed except to use the bathroom, and that he was consuming close to thirty thousand calories a day.

Mac worshipped his belly day and night, feeding him, helping him shower, then fucking him as though that had been how they’d lived all these years instead of with pent up sexual tension and aggression.

In a single day, they’d went from roommates to – well, Mac wasn’t exactly sure and at the moment, he really didn’t care either.

Dennis had gone from crying about how fat he’d become to cherishing every single thing that he ate, and Mac loved to watch him indulge in every dish. (He especially loved to feed him, and Dennis admitted that he quite enjoyed it too.)

“Mac – Mac, oh fuck, Mac!” Dennis called out as his hips bucked upwards and Mac slammed down onto him as he came, head tipping back as Dennis gripped his ass. His belly quivered, the muscles buried underneath a good fifty pounds of fat contracting as he emptied himself into Mac.

“Holy shit,” Mac breathed the words out even though he had yet to orgasm himself. Truth be told, there was something he’d been wanting to do, but he had to wait until Dennis was finished eating.

“You want me to take care of you?” Dennis asked as he rubbed Mac’s side, and Mac shook his head.

“Not today. There’s something else – something else I want,” he replied, then slowly climbed over Dennis’ stomach and straddled his chest. “Wanna fuck your tits,” he said, and Dennis’ eyes widened as his rested his hands on Mac’s taut waist. He picked the bottle of lube where it had been laying on the bed and coated his blushing cock with the slick substance before he grabbed Dennis’ tits and began to fuck them.

“Jesus Christ, you’re a slut,” Dennis playfully chastised him as the bed squeaked, headboard banging into the wall.

“You’re goddamned right I am,” Mac agreed, moaning as warmth started to spread through his stomach. “Fuck, you’re so fucking hot! So fucking thick and amazing and soft. So soft,” he murmured, pace speeding up as he started to get closer. Less than a minute later, he was painting Dennis’ chest with his cum, white spurts erupting from the tip of his dick until he finally softened.

Dennis moaned underneath him as Mac proceeded to lick him clean, as that had become their new custom.

Mac collapsed next to him once he was finished, pushing the sweat-soaked bangs from his forehead then laid on his side so he could admire how high Dennis’ belly expanded outwards.

“I kind of don’t want to leave tomorrow,” Dennis conceded as he rested his hand on top of Mac’s. “This is the most fun I’ve had in a while.”

“Really?” Mac questioned, the gears in his head already starting to turn.

“Well, yeah, now that I’ve gotten past the fact that I may never see my feet again,” Dennis joked as he patted his stomach. “It’s been…I don’t know, it’s been nice,” he shrugged, and Mac couldn’t help but stare at his tits as they jiggled with each movement.

“Huh, um, you know, there’s a chance that we could extend our stay by another week. All I have to do is call the front desk,” Mac offered casually, and Dennis peered over at him, one eyebrow arched.

“I thought you won this via a radio show,” Dennis reminded him, and a deep blush spread across Mac’s cheeks.

“I may have been lying just a little bit,” he said as he held up his thumb and forefinger.

“Oh, you don’t say,” Dennis deadpanned then started to grin as he looked over at him. “As long as we don’t have to pay for it, I really don’t give a shit.”

“Well, Dennis, you’re in luck because Frank’s been paying for it the entire time!” Mac announced happily and Dennis chuckled.

“Kinda figured.” The smile slowly eased from his face as he looked down at himself. “I’m never going to hear the end of it when we get back. Especially from Dee. It’s going to be one fat joke after another.”

“Fuck her. You know she’ll only be jealous because you realized that you can be big and beautiful,” Mac shot back then leaned over and kissed him. “And she’ll be a bony sad bitch for the rest of her pathetic life.”

Dennis sighed then shook his head. “You know what, you’re right. I have to admit it, it’s weird not giving a shit about what I eat. All these years…and fuck, it feels good to eat. Even if I do look like a cow now.”

“Nope, none of that,” Mac said as he rolled over on top of him and placed a finger to his lips. “No name calling, no self-deprecating humor. You’re fucking delicious like this, and I say, how about we make you even more delicious,” Mac suggested as he began to trail his fingers over his belly.

“Sounds good to me,” Dennis grinned, and Mac leaned down and kissed him again. “I am a little curious.”

“About what?” Mac asked as he reached for the phone to call for more room service.

“About those pills that you gave me. I noticed you stopped.” Dennis ran his fingers over Mac’s back, staring at him expectantly.

Mac sighed as he toyed with the cord on the phone. “If you must know, they were appetite stimulants.”

“I knew it! I knew those goddamned things weren’t vitamins! You dick!” Dennis scolded him though there was no heat in his tone.

“Well, how else were you supposed to realize your full potential?” Mac countered with a shrug.

“My full potential for what? To get fat?” Dennis shot back, and Mac started to laugh.

“Something like that,” he mumbled then started to order more food, Dennis consistently adding to the order every time Mac thought he was done.

“You know, I just thought about this,” Dennis murmured later that night as Mac massaged his belly after a special fourth meal.

“What’s that?” Mac asked as he started to plant light kisses over the waistline that had expanded from a size thirty-two to a size forty-two in the last three months.

“What the fuck am I going to wear home? None of my clothes are going to fit. I tried on one of my t-shirts the other day and – let’s just say it doesn’t quite cover everything anymore.” Dennis grimaced as he peered down at Mac.

“I kind of prepared for that,” Mac replied. “I, uh, I made sure to bring a set of roomier ones for you.”

“This was your plan all along,” Dennis mused, and Mac shrugged.

“It worked, didn’t it? We both got what we wanted.” He resumed the light patter of kisses, reveling in how much Dennis’ belly had expanded in the last two weeks.

“But did you plan for an extra week?” Dennis questioned, and one of Mac’s shoulders shifted fractionally.

“Guess you’ll find out, won’t you?” he quipped, and Dennis groaned.

“Christ, I’m going to weigh three hundred pounds before this is over with,” he said, and Mac started to chuckle.

“Doesn’t hurt to have a goal in mind. How about we get started first thing in the morning?” he insisted, and Dennis rolled his eyes but leaned up then kissed him.

Mac fell asleep with his arm wrapped protectively around Dennis’ belly and a smile on his face.

His plan had been successful, and life was good.

And he was most certainly going to help Dennis reach that next milestone.
