The alien grins as you walk through the door. He's been waiting for you, still parked on the sofa where you left him snoozing this morning. The room reeks of him, of his musk. It's so thick you could almost swear you can see it hanging in the air like a musty haze. It sticks to your skin and makes you warm and damp all over. God, it's good to be home. You drink him in some more, eyes lazily drifting across his body. That massive, doughy gut, covered in musky hair. Those four thick, strong, flabby limbs. That sofa-filling ass, and the tree-trunk legs beneath it. Between those legs were the fattest, hairiest balls you could've ever imagined. Just giving them a look filled your mouth with saliva. You hoped you'd be tasting them before long. "Enjoying the show, pet?" He rumbles, his voice deep, and warm, and smooth. You blush and nod, and he does a little showing off for you. Lifting his arms to tease you with the hairy pits beneath. Smooshing his flabby moobs together. Reaching back and smacking his fat, hairy ass to send it wobbling. He even reaches down and hefts up his monster cock, rolling the excessive foreskin back and forth over its half-hard length a few times for good measure. You can't help yourself; you're drooling. In more ways than one. Without another word, you start stripping. He doesn't speak as you do, just watches, taking his own turn to savor the sights. Those glowing green eyes of his never leave your frame as you undress. They trail along the curves of your body, lingering on the weight you've been putting on under his orders. He seems pleased, his wide mouth splitting into a toothy grin. His tongue rolls over those teeth, and you shudder. "Welcome home boy! Have a nice day at the rat-race?" He asks, stretching out on the sofa a little more. You nod, and he grins again. "Glad to hear it! Miss your Master while you were out?" You nod again, more enthusiastically this time. He grins wider still. "Mnnn, glad to hear it pet. Now, finish getting naked and then go fetch Master a beer." He huffs, settling back into the sofa and flicking on the TV. You don't hesitate to do as you're told, quickly peeling off the last layers of clothes. All that's left are your thick black collar and the snug metal cage around your cock. Master Stitch has the keys to both of those, of course. The former never comes off, and the latter hasn't been off in months. Part of you silently hopes he'll let you cum tonight, but the well-trained pet in you knows he won't. You step out of your discarded clothes and gather them up off the floor, leaving the living room and hurrying to your bedroom. Well, it was Master's bedroom, but you slept there too. At the foot of the immense double king bed was a small chest where Master let you keep all your things. Clothes for work, personal items, whatever was left over from before Master moved in. You smiled as you dumped your dirty clothes in there, free of your connection to the outside world. Now, nude and ready, you could slip back into your pet mindset and relax after a long day at work. Your next stop was the kitchen, fetching Master his beer. More accurately, you rolled a keg out for him. Booze barely did anything to him, the alien to imbibe gallons of even the hardest stuff before he got even slightly tipsy. He mostly drank it because of how gassy it made him. It certainly did that, you thought, as the alien hefted the whole keg up like it was nothing. He bit into the side of it and started chugging, emptying the whole thing in a matter of moments. He loosed a long, rumbling belch as he crushed the keg like a can and tossed it aside, making the room reek of booze on top of his warm musk. "Mnn, now THAT is breakfast." The alien rumbled, scratching his gut. You'd figured he'd been sleeping all day again, but you didn't really know until now. It explained why the living room was so muggy though. Not that you minded, of course. Just breathing in that heavy musk had your cage snug and your cock drooling. You couldn't help but whine a little, giving your balls a squeeze. Stitch seemed to notice that, grinning over at you. He waved his hand, and you hurried to his side. With a tug, you were pulled right up against him, sinking into all the warm, sweaty fur. You groaned, eyes fluttering shut as Master shoved your head under one of his arms. "My poor pet. All pent up and needy." He teased, locking your head under his arm, one of his other hands squeezing your balls. "Wants nothing more than to blow a big, sticky load for Master... don't you pet?" It was hard to hear him with your face buried under so much warm, musky flab, but you managed to and gave him a nod. He rewarded you by shoving your face in further, smothering you in his damp pit-hair. "Well keep dreaming, pet. Master might just weld that little thing shut and make your cock worthless forever!" He laughed, frame wobbling around you. You whined and pushed yourself into his pit, huffing his scent and hoping he was fibbing. It was hard to worry about it either way, his scent fogging your brain up. Every breath helped you relax until you were slumped and motionless against his side. Master kept you there for a good long time, though you're not sure HOW long. He just lazed and watched TV, letting you stew in his pit and soak in his sweat. He liked to do this to get his scent on you, nice and thick, whenever you came home from work. He'd said in the past he HATED how you smelled when you got home. Like paperwork and cubicles. You hadn't really noticed it at first, but the more time you spent at home, the more you could feel it. The awful, cloying stench of your life away from him. Getting to wash it all away in his sweat was one of your favorite parts of the day. "Still with us?" He rumbled, snapping you out of your haze. You weren't in his pit anymore, just slumped across his wide, soft belly. He was smiling softly down at you, hand cupping your cheek. "You're so cute when you're all zonked out, pet." He snickered, getting a blush from you. He leaned in and gave you a long, warm kiss, his plush lips pressing to yours and his fat, thick tongue slipping into your mouth. The cute moment devolved into Stitch tongue-fucking your mouth and throat, making you gag on his drool and that long, slimy slurper of his. He really was a great kisser. With a sloppy slurp, he pulled his tongue back, leaving you gagging and gulping down his spit. He gave your belly a soft pat as you swallowed, giggling a little as you struggled to get the thick slobber down. "Come on pet. I don't need to give you more training, do I?" He teased, making you squirm. 'Training' probably meant he'd pin you under his belly and make out with you all day again, forcing drool down your throat until your belly swelled with it. You'd been bloated for days after that... Suddenly, the earth was moving beneath you. Well, Master was, at least, hauling himself upright. You rolled off his belly and stepped back, wiping the last bits of spit off your face and watching him rise. It was, as always, quite the sight. All that belly heaving, balls sloshing as they were shoved out of the way to make room for his feet, his immense shaft bobbing and bouncing beneath his gut... you felt yourself throb in your cage again, a quiet whimper escaping your lips. "Aww, even watching me stand up has you leaky, huh?" He teased, stepping up and pressing his belly into yours. He was a foot and a half shorter than you, but you never felt 'big' next to him. Even looking down at him, he was imposing, his flabby gut smothering yours. You watched as he pushed past you and waddled into the kitchen, his fat nuts dragging on the floor behind him as he went. "Mnn, go get the playroom ready, pet." He rumbled from the kitchen, stuffing his face directly from the fridge. Snacks and beer and who knows what else, all vanishing down his gullet. When he was really ravenous, he sometimes forgot to unwrap things and just gobbled it all down, whole. That was always impressive to see. You gave his little mini-feast one last look before hurrying off to do as you were told. The 'playroom' used to be your room before Master moved in. He had you sell or throw out everything that had been in there, save for what you could keep in that chest at the foot of the bed. Then he had you remodel the room into a den of debauchery: shelves all along the walls holding his many over-sized toys, the floor padded with a thick black rubber sheet, sex-slings and fucking machines strewn about. It was a paradise for any pervert, and it was your job to keep it all clean and neat. You weren't sure what Master had planned for tonight, so you laid out the essentials. A huge jug of lube, a few of his favorite dildos, and a few more reasonably sized toys in case he wanted you in the sling tonight. Your rear quivered at the thought, still gaping and loose from the hour-long tongue fucking he'd given it a few nights ago. You could tell Stitch was in the room by smell before sound or sight. Just the warm, muggy musk pouring off of him was enough to let you know he was behind you. That and the massive, half-stiff cock pressing into the small of your back. The foreskin was warm and glistening with the alien's pre, smearing it across your bare back as he pressed in a little more to tease. "I wanna try something different tonight." He huffed, waddling over to a low, sturdy sex-sling hanging from the ceiling. It had been QUITE the challenge getting one that would work for him, but with some tinkering, you'd managed. He slipped into it and sighed, comfier here than in any bed or on any sofa. Oddly enough, he didn't pop his balls into the secondary, smaller sling built next to his main one. Getting those huge orbs out of the way was important for any good rump stuffing session. "You're gonna take Ol' Faithful over there..." He pointed to his favorite toy, a four foot long pink double ended dildo about as thick as your torso, "... and you're gonna cram him in my cock tonight instead of my ass!" He seemed excited, cock pulsing and slowly stiffening further. It was rare to see Master's monster cock get harder than half mast, so he really must have been eager to try this. With a blush, you wheeled the toy-cart over and hefted Ol' Faithful up off of it. You'd lifted this massive silicone thing so many times it'd put some muscle on your arms! Like usual, you slathered a thick, gooey coat of industrial lube over its head, but instead of cramming it between Master's furry cheeks, you aimed for his cock-head instead. Stitch's cock was huge, heavy, and covered in a foreskin so thick you could use it as a tent. Said foreskin drooped over the edge of his shaft heavily, soft and stretchy and oh so musky. Even now it was drooling pre all over the place, the floor slick beneath the sling. It was a bit clumsy to maneuver, but once you managed to get the tip of that toy against Stitch's foreskin, it slid right on in. That was the easy part though. The hard part would be finding his cock-head, buried under all that soft, pliable foreskin. With slow, careful nudges you poked around inside his foreskin with the toy, trying to find just the right spot to push. All the while trying to ignore your own throbbing, caged arousal. "C-come on, a little higher..." Stitch panted, squirming in the sling. His shaft bobbed and throbbed as you dug around in his foreskin, slowly growing stiffer. That helped, thankfully, and with a few more prods you felt the toy kiss up against the alien's urethra. He let out a soft, pleased hiss as you began to push forward, his shaft slowly opening up and letting that toy in. After months and months of playing with Master's gaping, greedy ass, it was strange to feel resistance as you pushed a toy in. It was odder still to see him squirming and biting his lip, the stretch clearly quite intense. He didn't give you any sign to slow down though, so you just kept on shoving. Inch by inch you fed his cock, the pink dildo slowly slurping into his over-sized member. You could clearly make out a bulge in the belly of his dick, and you used your free hand to gently rub and tease it. That made him squirm even more, the fat alien panting and squirming in delight. "A-all of it! use more lube if you have to, I want my cock to SWALLOW it!" He panted, face scrunched up as you pushed the toy in past the halfway point. You took that as a hint and hit the toy with another layer of super-lube, making its descent into your Master go much more smoothly. He seemed quite relieved at that, relaxing back in his sling and savoring the sensations of his cock's 'snack'. The last few inches went surprisingly quickly. One moment you were pushing the toy's second head against his foreskin's opening, and the next you felt it -slurp- into his cock, his urethra closing around your hand as you pushed. The bulge in the bottom of Stitch's shaft was thick and heavy, and as you watched him squirm you could even see it still moving deeper. Taking the initiative, you reached down and heaved his cock upwards with both hands. That massive shaft was now pointing straight up, and with gravity's help the toy inside began to slide even faster towards Stitch's groin. He clamped his eyes shut and let out a whimper, legs flailing cutely as the tip of the toy pushed past the base of his cock. It slid a few inches in... and stopped. Stitch didn't seem to notice the toy stopping at first, still just squirming and panting as his insides were stretched. You tried to help Ol' Faithful along with a few shakes of Master's cock, but it didn't help the toy sink in any deeper. Eventually, Stitch noticed this, and his eyes slowly drifted open. "W-what's wrong?" He panted, peering past his gut and shaft at you. You explained that the toy had stopped, seemingly stuck, and he groaned. "W-well then get it unstuck! I want to feel that thing splash down in my balls, goddammit!" He ordered, sounding more desperate than angry. You nodded, letting his cock go to think for a moment. First, you opened the lube bottle's cap and up-ended the whole thing into Master's cock. The belly of his shaft swelled with the slime, and as you lifted his shaft again you could see the toy slowly sliding in deeper. It wasn't fast enough though, you knew, and that's what made you wheel over the fucking machine. It was a very simple contraption: a motor moved a piston in and out, and on the end of that shaft you could slip one of Master's dildos or other toys. You'd used it to fuck his rear, and even slapped a flesh-light on it once to milk his shaft. This time, you'd do a little of both. You slid a 'normal' sized toy over the piston, a three foot long, smooth dildo. Normal for Stitch, at least. It bore no features, no nubs, making for an easy glide. It didn't need to do much, just push. Next, you flopped Master's cock back down from its upright position, aiming its tip at the machine. Then, it was just a matter of hitting the switch, and it started working. There was more than enough lube in Master's shaft for the toy on the machine to slip right in, stretching his foreskin and urethra open with ease. It was half as thick as the toy already in there, after all. You started with a low speed, just to warm Stitch up, then you slowly began to crank up the tempo and the depth of the machine's thrusts. Inch by inch, the tip of the machine's toy, and the tip of the toy already inside Stitch grew closer. Every sloppy thrust the machine made went deeper and made your Master squirm even more. You weren't sure if they'd met or not, but when Master let out a happy howl, you knew. The toy already in him was bumped a little deeper, and on each of those bumps, he whined and squirmed in bliss. You grinned and sped the machine up, making it slam into the buried toy over and over, sending it deeper on each thrust. "Th-that's so fucking good..." Stitch groaned, eyes shut and mouth agape as his cock was fucked. "T-This is gonna HAVE to be part of our routine fr-from now on, pet!" He huffed out, barely able to get the words out between moans and whines. You took a mental note of that and smiled, turning the machine on even higher. A few more thrusts from the fucking machine and Stitch stopped moaning. He was still shuddering from delight as the machine's toy slurped in and out of his slimy cock-slit, but he wasn't whimpering in pure bliss like before. Eventually, he sat up and looked over at you, still panting. "It's not hitting the toy inside anymore... get the Cannon." He huffed, trying to buck into the toy's thrusts. You gulped as you heard him say that, but you didn't question him. Last time you'd doubted him aloud, he spent a week sitting on your face as punishment. You just turned the machine off, pulled it out of his shaft, and pulled the current attachment off. Setting the slimy thing aside, you walked over to one of the shelves, and gulped as you looked at the Cannon. Jet black and shaped like a billy-club, the cannon was Stitch's largest toy. Even for his experienced rear, it was hard to take, and you could see why. It was over six feet long, and the widest part of its length was too fat to fit through the doorway! You'd had to knock out a wall to get it into the room when Master brought it home. You'd always wondered WHERE he'd gotten the immense thing, but you'd never bothered asking. With a grunt, you heaved the Cannon up in your arms and began hefting it over to the machine. It was made of thick black rubber stretched over some kind of squishy gel core. That meant it wasn't quite as heavy as it looked, but it was still DAMN weighty. Stitch was usually the one who moved it about, but he was too busy humping at the air to help you. You could still see the bulge the toy made in the base of his shaft, about half of the thing 'swallowed' by now. A few more moments of awkward shuffling later, and you managed to move the Cannon over to the fucking machine. It took a few more moments still to hook it up, and once you had you again had to aim and prep the machine to penetrate Master's cock. He felt the tip of the Cannon press against his foreskin and he groaned. "U-Use manual control. Ease it in slow and j-just gently push the toy in deeper." He panted, looking a little worried as he felt his foreskin stretching around that monstrous toy. You did as he asked, of course, taking the small controller from the machine and using it to gently, slowly guide the Cannon in. Even with your hand guiding it, it was a challenge to get the tip of the fat, blunt toy into Stitch's shaft. He actually had to lean forward and hold his shaft steady as you guided the toy in, his urethra eventually giving way and letting the Cannon start to enter. Every inch was a slow stretch, Stitch relaxing back in the sling and trying to think happy thoughts. He'd never admit when he'd met his match, of course, so even as the Cannon stretched his cock to obscene levels he didn't ask you to stop. He did whine, moan, and wriggle all around though, not an inch of his flabby frame still as you drove the toy in deeper and deeper. The thickest point of the Cannon creeped closer to the tip of Stitch's cock, his body shuddering as he was stretched wider and wider. You were quietly a little worried your Master had overdone it this time, but you pushed the toy further in despite that. It was quite a sight, seeing his cock double in width as the toy pushed inside, stretching that fat alien dick out much further than the first toy had. "That's it..." He hissed through clenched teeth, his hips bucking a little as you drove the Cannon in deeper. You watched with a gasp as the fattest part of the toy finally pushed into Stitch's foreskin, entering his urethra seconds later and making the immense alien squirm and whimper. His cock-slit was stretched so wide you could've easily crawled in yourself if the Cannon wasn't in the way! The thought of that distracted you more than a little, and before you knew it more than half of that shiny black behemoth was buried in Master's shaft. "Almost!" He huffed out, face blushing and eyes screwed shut. The Cannon creeped deeper, inching ever closer to... "Ahh!" Stitch cried out as the Cannon pressed into Ol' Faithful inside of his cock, forcing the smaller toy in deeper. You stopped the machine, just for a moment, giving your Master a chance to catch his breath. He clearly needed it, sweat dripping from his fur, tongue lolling out as he panted and fought to catch his breath. "I-I can do this... probably..." You heard him murmur under his breath. You couldn't help but chuckle a little, and thankfully he didn't hear you. Through all this, you hadn't been worried about Master's health, because you knew he was nearly invincible to anything short of a star-ship mounted plasma cannon. What could go wrong, however, is his pleasure centers could get overloaded and he could 'short out'. It had something to do with how he was made, he'd told you. Last time he'd really pushed his limits, trying to fit an entire car up his greedy ass, he'd had a short. For days after that, he could barely talk! Like a trance, a short turned him into a quite lump of alien. Mind slower, limbs less responsive, everything clumsy and slow... even his eyes stopped glowing their brilliant green, turning jet black. It was pretty cute, actually, seeing him all clumsy and goofy. He found it less cute, not getting to boss you around and ending up a helpless lump of lard. "Let's just... pause..." he panted out, trying not to move his hips too much. "I don't need to spend the next week as a mindless moron." He added, though you could have sworn you heard a hint of temptation in his voice. Despite how annoying the shorts were for him, he clearly enjoyed his time spent as a big brainless butterball. You spent a while mulling that mental image over, leaking in your cage, as he tried to catch his breath. "Okay, j-just a little." He grunted after a few moments of rest, bracing himself in the sling. "Just a little push." You picked up the controller again and did as you were told, forcing the Cannon in just a teeny bit more. Stitch let out a low groan, eyes rolling back and cock throbbing around that immense toy. "Again!" He huffed, and again you pushed in, forcing the buried toy in deeper still. "I-It feels like Ol' Faithful is stuck again..." he groaned, reaching down with one hand to feel at the side of his shaft. "Like it can't quite make it..." You could almost hear the gears turning in his head as he tried to figure out his next plan, and judging by the heavy blush on his face it was a doozy. "Back the Cannon up a foot or so... then just SLAM it into me, full force!" He ordered, trying his best to sound confident. You couldn't help but hesitate, which he noticed. "Just DO it, or I'll have you pull the Cannon out and YOU can go in there and start pushing!" You gulped and nodded, silently wishing he'd let you do that anyways, cock throbbing in your cage. Master's 'punishments' were always too hot to really bother you, but you knew that was on purpose. With a button press, the Cannon retreated a foot or so. Stitch seemed to be getting used to its girth in his cock, the fat blue perv barely squirming as it moved. You turned the machine's force up to max, and your finger hovered over the 'forward' button for just a moment longer. You looked up to Master, and he just grinned and nodded. Without anything else to do, you pressed the button. There was a soft hiss as the machine SHOVED the toy forward, followed by a bellowing howl from Stitch. If you had to guess, that thrust had been more than enough to get Ol' Faithful where he wanted it. You looked to those huge, sweaty nuts resting on the floor, but you couldn't seem to see any bulges there. You were confused for a brief moment before you heard your Master mumble something. "W-wrong tube..." He panted, looking almost sick. One hand was pressing on his belly, and as you stepped closer you realized why. Stretching out his fat, furry hide was a very familiar shape. "I-It's in my bladder!" Stitch gasped, rubbing at the bulge in his lower gut. "H-how did... well that explains why it got stuck..." He trailed off, shuddering as he felt the bulge in his middle shift. "I-Is it bad that..." he kept on panting, turning to grin at you from his spot in the sling. "Is it bad that this feels REALLY good?" he laughs a little, and you shake your head no. He smiles and hefts himself up in the sling a little, rolling out of it and standing. He has to keep his legs wide to give that bloated shaft of his room, his gut pressing down into as he leans forward. "Yeah, it's really in there..." He gasped, rubbing over the bulge in his lower tummy. "What a weird feeling... I like it!" He laughs, belly bouncing. You could almost hear the toy sloshing about in his bladder as his gut wobbled. "Now..." Stitch turned his attention back to his over-stuffed cock, the Cannon still keeping his meat wide. "Think we should get this out, or see if we can 'lose' it too?" You just stared, cheeks red with blush. Master couldn't even take all of the Cannon with his rear, and here he was trying to get you to cram it into his bladder! You opened your mouth to suggest he take it easy, but before you could even say a word he was awkwardly shuffling his way forward. With his cock still wrapped around the Cannon, every step made his meat swallow up a bit more of it. It wasn't long before the blunt tip of it was kissing at the same opening it had been forcing Ol' Faithful through, the alien shuddering as he felt it. "Mnn, there we go..." he groaned, reaching down and groping his underbelly. "Now go and turn the machine on, pet. One slow, steady push." He ordered. You were stunned, just standing there and gawking for a moment before your feet finally began to move. You found yourself back at the machine's controls and trying not to think about it too much, you punched a few buttons. Just like Master wanted, the toy began to slowly advance, pushing deeper into his cock. "Fuck..." He huffed out, back arching and hips shoved forward as the toy began to force its way deeper into his body. "Gonna need something bigger for this..." He thought aloud, getting your eyes to widen once more. Was his cock and bladder really THIS stretchy? That's when you noticed something. The glowing green of his eyes was starting to dim. "Master..." You managed to start before he suddenly SHOVED himself forward onto the toy. With one quick push, he managed to get the tip of his cock and the base of the Cannon to kiss, lodging the fattest part of the toy in his bladder along with Ol' Faithful. The slight bulge in his underbelly turned into an immense bloat, the double-ended toy pressed tight against the skin by the huge toy pressing into it. "Yes..." He whined, eyes glowing brightly again for a moment before going dark. He shorted out, cock stuffed and bladder swollen well past his limits. You sighed and watched as he slumped over the machine, a dumb grin on his face. He was probably jizzing right now too, but with the Cannon blocking his cock, it was impossible to tell. It didn't really matter either way. He was lost to the world, mind overloaded with bliss and body barely able to move. With a groan, you turned the machine off. You figured it'd be a good idea to pull the Cannon back out before long, but you didn't wanna push the alien's buttons again so soon. Lord knows what that would do to him in his current state. Hell, pulling the toy out at all could prolong his stupor. Maybe... with a bit of a blush, you stepped up and disconnected the Cannon from the machine, leaving it buried in Stitch's cock for now. It was in there really snugly, after all, and better to leave things as they were rather than make them worse, right? No longer attached to the machine, you managed to guide Stitch back a few steps. While he was shorted out, it was kind of like he was sleepwalking. He wasn't entirely immobile, but you had to help guide him back away from the machine and towards the center of the room again. You looked over to the door and realized that, with the Cannon in his cock, Stitch was stuck in the playroom for now. With a chuckle and a sigh, you led him to one of the room's corners, letting him rest against the wall. Leaving him there for now, you started cleaning up. Washing the other toy Stitch had used was easy enough, the playroom had a built-in floor drain and a hose. A quick rinse and the smaller toy was ready to go back on the shelves. Then you hosed off the floor, getting all the jizz and lube and sweat and drool to flow down the drain. Just like that the room was clean, save for the mindless, moaning alien in one corner. You walked back over to him and gently patted his head. He smiled a little, nuzzling into your hand. He really was pet-like like this, all cuddly and warm. Maybe you should sneak a collar onto him... Nah, he was already going to be angry enough, zonking out again. His fault or not, you were still gonna get 'punished' for this. Part of you was a little worried it'd mean that cage was gonna end up welded, but you knew whatever happened you'd love it. With a bit of gentle shoving, you got him to sit, nestled in the corner with his stuffed cock and fat balls in front of him. You gave that massive shaft a pat, getting a soft moan from him, and turned to leave. A few days, maybe a week, and Stitch would be right as rain again. You blew a kiss to him, and left the room, leaving the lights on and the door open for when he woke back up.
