“Come on Chelsea, you need to start working out. If you don't that flab of yours is only going to get worse.” “I know, I know, but you said you liked my flab though. I remember a certain mink snuggling up with it a lot.” I blushed a bit. She was right of course. I did enjoy how soft and pudgy the badger was. But New Years was right around the corner and she needed some sort of drive going into the new year. Losing weight was a common enough goal and I wanted to work out more myself. Not that I really needed to exercise, but getting in shape was never a bad thing. “We can go together and help each other out though. It'll be fun!” I smiled softly at her, but the badger still seemed a bit apprehensive. Chelsea sighed softly. “Fine I guess, just nothing too intense ok? You know I don't have the same stamina as you Trish.” I clasped my hands, my tail swishing a bit. “Good girl! Get ready then and let's get going! There's a new gym that opened up near by so we can get started immediately!” The badger groaned. “Really?! Why can't we start once the year is over?” “If we did, you'd probably be even fatter by then. You need to start while the idea and motivation are still fresh! Come on.” I grabbed her hand and tried to pull her up off the couch. It took a bit of convincing to get her up and dressed, but we were out the door shortly after. Chelsea wasn't overweight by any means, but the badger was chubby. It was that cute sort of pudge than made most of her clothes barely fit, her belly poking out from underneath her shirt. I always thought it was cute. Compared to her, I was a twig though. My body was much leaner and thin, where as Chelsea had size and weight to her. We were complete opposites, but she was the best snuggler I knew. Going to bed at the end of the day was always the best. Rounding the corner past our apartment, the gym was in sight. Globus Gym. I had heard that it was a premiere gym popping up all over the place. A lot of furs were going to it and it was really convenient that it had opened up near us as well. “Do we really have to do this?” I sighed. It was at least the third time Chelsea had asked me since we had walked out the door. Don't get me wrong, I love my girlfriend. But once she was set on something, she was all for it, or against it. “Yes Chelsea. Come on, don't you want to be a bit thinner? I mean, you'd look a lot sexier with a thinner body with these huge tits of yours!” I groped her chest a bit to get my point across, the badger blushing a bit. She always made me jealous that she was so large. My A cups looked downright nonexistent to her massive G cup tits. “I-I guess that would be nice...” “Good! Now let's go inside.” With no further complaints, I brought her inside along with me. The gym was as big as it looked on the outside. Wide, expansive and full of all kinds of workout equipment. It made me excited to get to work when I saw the place filled with all kinds of people working out. As I looked, it seemed there were only guys there with trainers helping them out. The trainers were downright ripped to all hell. They were all huge females with muscles I could only dream of. I gulped a bit, intimidated somewhat by them. Next to me, a german shepard guy was impatiently looking at his watch. He seemed to be a bit nervous, looking from his watch and then over to a door at the back. “Everything alright sir?” He was a bit surprised I suddenly talked to him, the man chuckling a bit nervous. “O-Oh, yes, I'm alright. It always takes my wife longer to do her workouts compared to me. If you have a mate, they do the workouts in a separate room from you so you can surprise each other with how much work you've put in. My wife loves how toned I've been getting, I'm just a bit worried with her pregnancy is all. She's gotten really big and I don't want her doing anything that might harm the kids...” Almost as if on cue, the backdoor opened and in walked a cocker spaniel lady with the biggest pregnant belly I had ever seen. It was huge and wide, the massive round belly nearly touching the floor. Not only that, but the lady was quite fat and heavy as well, her weight forcing her to waddle over to her husband. The two lovers embraced and kissed softly. “Sorry for keeping you love, the trainers wanted me to take an extra long workout today!” “That's alright dear, I was just a bit worried, but you seem to be fine! Let's go, I'm getting hungry.” The cocker spaniel murred, the thought of food very pleasing to her as they headed out the door. As she walked by me though, I got a whiff of several different scents. It was quickly dismissed as a large figure walked up to me and Chelsea. “You two here to join the gym?” Looking over, a large elephant woman stood before us. She was several feet taller than both of us, her tits just as big as Chelsea's were. She was intimidatingly large, but I smiled up to her. “Yes ma'am, we're both here to join the gym and work out. My girlfriend really needs to loose some weight here and I'm looking to get a bit more toned.” Chelsea blushed a bit at how blunt I was, nudging me some. The elephant looked us over, as if examining us. “I see. You both a couple? We have a special program here for couples. We take you into separate rooms and work on you both apart from each other. We do this so that the gains are a surprise to both of you. If you were both in the same room, it gets to be too distracting and negates the gains we're trying to achieve for both of you.” “I see, it sounds interesting. Would that be alright with you Trish?” The badger seemed a bit nervous. “I don't know... No one will make fun of my size, right?” The badger asked the elephant, the large lady grinning wide. “Of course not. In fact, we love people with your size here at Globus Gym. Your body type is the best for us to work on and get into shape.” The elephant's gaze was deep on Trish's body, the elephant licking her lips. “In any case, it's 100 dollars a week to work out here, but you can come in whenever you want. That means it'll be 200 dollars a week for both of you.” I winced a bit. That was a lot of money to come out of my pockets, but this place had such a good reputation that I couldn't let it pass up. “Alright, we can do that. Is there any paperwork that we have to do?” The elephant nodded and brought me over to a desk, pulling out a few forms. Just some basic information they needed to fill out for both of us as well as my credit card details for the weekly deposits. Once they were all filled out, the elephant took the papers and filed them into the computer on the desk. She then looked around and called over a rhino trainer, the lady buff, but not quite as large as the elephant. “You can have the skinny twig, I've got the fat ass in the back.” The rhino grunted as the elephant grabbed Trish's hand and began pulling her into the back, the badger stumbling over her feet a bit. “Work hard love, I'll see you once we're done!” I called out as she was pulled into the back room. She gave me a slight look of worry, but I dismissed it. They seemed pretty keen on helping us and the rhino then brought me over to the equipment. The rhino started me on light settings for most of the equipment, easing me in to the workout. She spotted me and made me go for a longer duration than I would've myself. I trusted her though, she was the trainer after all. Hours flew by, the workout distracting me. Before I knew it, my body was exhausted, sore from the lifting and pushing of weights all afternoon. The rhino complemented me on my stamina and thanked me for coming in, letting me gather my stuff and wait near the front end for Chelsea. I watched as the rhino walked into the back, wondering how Chelsea's workout was going. I waited on the bench at the front end for what seemed like a long time. I kept glancing at my phone as the hours passed by. I was a bit worried, but I figured they were just pushing Chelsea to her limits. I watched as other people came in and worked out, trainers coming in and out of the back to take care of him. I even saw the rhino come back out, but something was different about her. She looked tired and sweaty, a large splotch also on the front of her shorts. It was only then that I noticed just how hung she was. She had a massive bulge in her shorts, the fabric stretched out immensely. Looking around, I noticed that all the other trainers were just as hung and ripped as her. Were they all herms? It as midnight by the time that Chelsea had finally came out from the back. I had nearly dozed off on the bench when I saw her waddle out. To my surprise though, she was much larger than when she walked into the back. Her belly was huge and round, her clothes an absolute mess. There was a thick white liquid on her face and chest, the badger moaning softly as she waddled out. “C-Chelsea?! What the hell kind of workout did they give you?!” The badger giggled and murred, smiling at me. “Hey Trish! You're right, this place is great! They gave me plenty of protein shake to drink. They said it'll help me build up muscle mass and lose some weight. Let's come back again tomorrow!” The badger's belly gurgled, causing her to burp loudly. The smell was very interesting for sure, an odd musky smell coming from her. I didn't know what to make of it, but I trusted the trainers. They knew what they were doing I suppose. The next day, Chelsea was eager to get to the gym. Over night, I could've swore she gained some weight. Her body seemed a bit thicker and wider, her clothes tighter against her body. I assumed the shakes that they gave her had some effect, but she didn't seem to mind it. I was still sore from yesterday, but Chelsea didn't seem to be sore at all. “Come on Trish! Let's go!” The badger pulled me along, my body a bit against moving. “N-Not so fast Chelsea, my body's still sore from yesterday. I'm surprised you aren't sore at all!” “Hehe the workout they gave me was pretty easy, so it didn't wear me out too bad!” She giggled as the badger pulled me along to Globus Gym. We were early to the gym this time, not too many people working out this early. The elephant was at the desk though, smirking as she saw Chelsea wobble in. “Ms. Rampage, I'm here for my workout today!” Chelsea chimed happily, the elephant standing up and walking over to us. “Heh, good slut, you came back again today. Gotta get your money's worth right?” The elephant smirked as she groped Chelsea's huge tits, feeling her up right in front of me. I suddenly felt a bit worried, but it had to be a part of the workout for her....right? I hear a stretching noise and looked down. I suddenly realized how hung the elephant was. If the other trainers had soda bottles in their pants, the elephant was hiding a cannon, the bulge extremely massive. The elephant lifted my mate up and rested her on her huge bulge, making her straddle it. “You can do whatever you want twig, the trainers and I are going to be busy training your slut in the back.” Without another word, the elephant carried her off into the back room, leaving me alone to workout by myself. I tried to workout the best I could, but I had a nagging feeling in the back of my head. Maybe it's cuz I didn't have anyone helping me, but I didn't feel like working out today. After about an hour, I stopped and walked over to the bench, my spirit to work out completely demoralized. As people started to show up to train, I saw trainers come out with wet splotches on their shorts. Some of them were even dripping the same white liquid from their shorts that Chelsea had on her yesterday. I dismissed it, there was no way my mate would cheat on me. They were all just messy drinkers and spilled the protein shakes all over themselves. As the hours passed by, the german shepard and his wife came walking back into the gym. The rhino and a ram trainer spotted them and smiled, the rhino taking the male aside and beginning his training. The ram walked over and pulled off the cocker spaniel's shorts, tearing them to shreds. She then pulled out her massive throbbing cock and shoved it straight into the dog's pussy, lifting her up on her massive cock despite how huge her belly was. “Come on slut, let's get you into the back to workout.” The ram said playfully, the cocker spaniel moaning out heavily as she was walked into the back room on the ram's cock. I gulped roughly. Was Chelsea getting the same workout as her? The hours passed by again, neither Chelsea or the cocker spaniel coming out of the back. I was getting worried that they were training her too hard, but she didn't seem to be in any pain this morning. Six hours passed until the cocker spaniel came out from the back, her massive belly even bigger than before. Her husband was happy to see her and acted like nothing was wrong, the two lovers embracing before they left. Was that the normal workout for the couples? I nearly dozed off again by the time midnight rolled around. I had waited on the bench all day for Chelsea to come back out, watching the different people that had came into the gym and left. It seemed the couples training was very popular here. The males that worked out were all the same, lean and toned. But so were the women the same as each other. They were all fat and pregnant, each of them coming back out bigger and heavier than when they went into the back. Was the same thing happening to Chelsea? As I sighed, lost in the boredom of waiting on my mate, she finally came back out. My jaw nearly hit the floor when I saw her. “Hey Trish,” she burped loudly, her thick body wobbling heavily. “how was your workout?” Chelsea was massive. There's fat and obese, and then there was Chelsea. She had huge thick rolls of fat all over her body, her belly so massive it rested on the ground now. It was heavy and round, her tits just as massive as her belly now. Her clothing was long gone, probably unable to fit on her massive body. Even her ass was huge and round, each massive cheek resting on the ground. How she was able to move still was beyond my comprehension. “C-Chelsea...?” I meekly asked. She giggled back, her massive thick neck rolls wobbling. “What's wrong? You seem like you've seen a ghost or something!” The badger smiled as if nothing was wrong. It was almost as if she didn't even noticed she couldn't even reach her face with her hands anymore. “I-I'm just surprised at how big you are! Did they give you more of those protein shakes?” She nodded, but it was barely noticeable with how thick her neck was now. “Yeah, they gave me a whole lot today! I feel amazing and strong! You were right, this place was great to come to!” The badger giggled as she walked out of the gym with me, finally heading home. When we got home, we quickly found out Chelsea couldn't lay down on our bed anymore. She was just too massive and wide now. I sighed as we slept, me on the bed and Chelsea sitting up on the floor. It was the first time since we had been mated that we had slept apart from each other. When I woke up the next morning, my mountain of a mate was gone. I was a bit confused, an odd feeling of coldness covering me as I woke up. Chelsea always kept me warm at night, her body was always nice to snuggle up against. I panicked a bit until I looked at my phone, seeing a message from her. She had left extra early to get to the gym. She told me I could stay home if I was sore from yesterday. I sighed, but she was right. I was still a bit sore. I guess I just wasn't used to working out at all. It was a New Year's resolution that was looking to be impossible for me to do. I got up and showered, going about my day as my mate was at the gym. It was midnight again and Chelsea hadn't came home. She had been at the gym all day and hadn't messaged me once. I had glanced over and looked at my phone every hour of the day, but she never messaged me or replied to my texts. I was getting worried. She had to still be at the gym, so I got up from the cold bed and walked to the gym. I was surprised to see the gym was still open. I guess it was one of those 24/7 gyms, where you could come in and workout at any time. Opening up the front door, no one was at the front. No trainers, no gym goers, no one. Were they in the back then? It was only then that I realized I had never been into the back room. In fact, how many people did get to see it? It seemed like the only people that went back there were females. If that was the case, how come I didn't get to go back there? What was so different about me that made it so I couldn't go back there? I was a bit nervous and intimidated. I walked over to the backdoor slowly and began to open it up. As I did, a large figure was at the door, the small slit showing only a tiny bit of the elephant. It was enough for me to see her glaring eye down on me. “You aren't supposed to come back here cuck...” She said gruffly. I gulped, the fur on my body standing on end a bit. I wasn't expecting the large elephant to be standing right in the doorway. “I-I'm sorry...but I came to see if my mate was here. You know, the badger?” I asked meekly. The elephant grew a large wide grin, the sight making my body go a bit cold. “Oh, I know. She's been one of our best new toys to play with. You really brought in a good slut for us to use.” Toy? Use? What did she mean? Weren't they just working out? “N-New toy?” I whimpered back. The elephant chuckled before she opened up the door for me all the way. The first thing I saw was the elephant's massive shaft, the erect cock at least as long as my body was. It was huge and throbbing, the massive length radiating heat and dripping cum from the tip. After I had gotten over the sheer size of her length, I looked past it to see an ungodly sight. In the room were dozens of women and trainers, but the women were all massive. They were huge and blob-like, their bodies unbelievably obese. And in the middle of the room was my mate, their current fuck toy and claim. Her feet no longer touched the ground, her fat thick legs lifting her up. Two of the trainers were going at her heavily, one fucking her massive ass as the other drilled her face. They were going harder and faster than any person I had seen drill a fur before. “Your mate was kind enough to sign up for our Blob Service. It was either that or our Breeding Service. Seems like she wanted to be a cum dump more than a breeding slut. That's fine with us though, we needed a tight new hole to blimp out.” The elephant chuckled as I looked on in amazement. I couldn't believe how massive she was, my mate almost recognizable. Chelsea simply sat in the middle of the large room as she was fucked senselessly, her massive body wobbling. I didn't know what to say or do. I just watched as her body wobbled. The elephant grinned again and clasped a hand down on my shoulder, her large palm nearly making me fall over. “I'll tell you what, why don't I cut you a special deal? If you take it, you'll be spending a lot more time with your precious wife. How about it, that sound good to you?” I gulped roughly as I looked up to the elephant. I missed Chelsea dearly. Every night without her was rough and miserable. I longed for the warmth of her body again. “O-Ok.... What do I have to do for that?” The elephant murred and chuckled, grabbing my shoulders. “You don't have to do anything...except be my permanent cocksleeve.” I meeped as she suddenly tore my clothes off my body, exposing my thin featureless body. “It's a shame you aren't like your mate. I enjoy someone with some size to them instead of a flat ass board like you. It's a good thing you sluts make better cocksleeves than fuck toys.” She lifted me up and lined me up to her massive cock, my body shivering roughly. Before I could do anything, her massive cock shoved into my backside, the pain causing me to yelp out. The other trainers in the room smirked and chuckled as they watched the massive length slowly push into me. It was only then that I saw other mates hanging off the other trainers cocks, suffering similar fates to what I was about to go through. They were deformed and stretched over their massive cocks, their bodies hanging limply as the trainer's cocks went all the way through their bodies. I winced as I felt the head of her cock push into my stomach, a huge bulge pushing into my gut and bulging it out. The elephant murred happily, liking how easily her cock was sliding into me. “Good slut...Take my entire cock...” She gripped my body and shoved into me hard. I grunted hard as her huge cock pushed against my rib cage, giving some resistance to the massive elephant. She grunted back to me as she thrusted hard into me, bashing my lithe body hard until she pushed past my rib cage, stretching me out over her like a condom. I felt the massive head of her cock hit the back of my throat, her salty pre soaking my tongue. I wanted to moan out, but her length filled my maw, slowly pushing more and more through me. With a sharp pop, she unhinged my jaw, her massive length finally breaching my maw. She moaned a bit, happy my body finally gave in as she pulled me all the way down, my small ass pushing into her musky crotch. “There we go... Welcome to your new home slut...” She chuckled as she walked over toward Chelsea. I got a front up view of her massive ass before my world suddenly went dark. For hours, all I could feel was the wet thick folds of my lover against me and the cum of the elephant. Both covered my body as she fucked the badger, my body hanging on the base of her cock helplessly. Once she finally finished, her cock went flaccid but still stretched all the way through my body. She pulled out of Chelsea and looked down at me, surprised I was even still conscious. “Heh, good slut. You better get used to that, cuz you're never leaving my length...” With those final words, my world went dark again, the elephant pulling her large pair of shorts over her length, hiding me completely from view. I wondered if anyone would even know I'm here or notice me. All I could smell was the musky scent of my master, the scent permeating my body completely. All I could do was accept my new existence, my body wrapped around the massive elephant's cock for good. At least I'd get the chance to pleasure my lower and anyone else the elephant shoved me into. That didn't seem like such a bad existence to me.
