Day One-

	Hi there. My name is Roland. I'm your average mouse guy; three feet tall, skinny as heck and barely any muscle mass. It's the New Years, and I want to change that! I'm sick of being the small skinny mouse everyone makes fun of. So starting today, I'm going to be working out and making a journal to keep track of things. Hopefully by the end of the month I can actually have some mass to me instead of the twig size I am now.

Day Two-

	Whew! I haven't hurt this much in a long time. I know I wasn't too physically active before yesterday, but I didn't think my body would be this worn out! My arms and legs hurt just trying to move them! At this rate, I'll be broken before I get any mass at all! Maybe I can try finding a gym or something to go to...

	I did some searching and found a gym nearby! Globus Gym. I've never really heard of it myself, but the reviews online are staggering! Perfect five stars and not a single complaint? I didn't think there was an establishment that could even provide results that good!

Day Three-

	I went to Globus Gym today. For a building as massive as it was, I was surprised I'd never seen it! It was massive, stretching up to the clouds! The place looked more like a corporate headquarters than a gym! Applying was pretty easy. They asked for the usual details and took my height and weight. Guess they were just as interested in my growth as I was. Makes things a little easier on me I suppose; won't have to keep track of all the numbers myself if they do it too.

Day Four-

	Man, working out at Globus feels great! Doing all this by myself wore me out, but after getting help at the gym, I feel like I can keep going! I was amazed at all the different people there though. All of them are massive and bulky, but not just in their muscles. Men have enormous bulges and women have huge breasts and thick asses! I was beginning to feel left out with how small I was, but someone came over to me to help me out. A gray feline by the name of Gus. Said he'd only been there a few weeks now. I was shocked when he showed me a photo of himself before. He used to be thin and lanky like me, but now he had bulk all over! Well, not muscle bulk. He had loads of fat on himself all over! I wasn't expecting that considering he had said he had been working out at the gym. How can someone gain weight at a gym and not lose it?

Day Five-

	I met the owner of the gym today. A massive hippo man by the name of Rogue. He's an interesting fellow. He's massive and thick like Gus was, but he certainly has muscle too. He was lifting up one hundred pound weights like they were frisbees. The thing that made me a bit uncomfortable was his massive bulge and the fact he only wore a speedo in the gym. Seemed like he was a bit of an exhibitionist as he liked to show off his massive size and strength quite a bit. His bulge was bigger than I was though, so when he got close to me, I could feel the heat and musk just radiating off it. It was a bit intimidating, but he welcomed me to the gym and told me if I needed any help to just ask him. He also recommended I drink plenty of their signature water; Hippo Thirst. An odd name for a drink, but it seemed like plenty of the people in the gym drank it. Everywhere I looked, a bottle wasn't too far away from someone working out.

Day Six-

	I haven't really been gaining much since I started a few days ago, but I have been feeling good lately. Gus told me he drinks Hippo Thirst constantly, even outside of the gym. It's his favorite drink and can't get enough of it. It made me wonder what was in it if Gus was so utterly addicted to it. I grabbed a bottle and looked for an ingredients list, but I couldn't find anything of the sort. A bit odd, but they probably made it locally near the gym. Would make sense for them to not have an ingredients list if that was the case. I tried some of it just to see what it was like. Wow, the shock and surge was intense! Even a simple sip sent a jolt through my body, pumping me with energy. I downed the whole bottle shortly after and got right back to lifting weights. The power felt incredible!

Day Seven-

	Man, when I woke up this morning, my body felt amazing! I haven't ever felt this good before in my life! I felt strong, energized and ready to work out. I was a bit startled when I walked into my kitchen though and found out I had bought over forty cases of Hippo Thirst! What the heck was I thinking?! I don't even drink energy drinks that much, but it's not really an energy drink either? I don't know, I was never told what it was. Before I could even continue my thought though, I was already downing another bottle! My body was reacting before I could even get my thoughts straight! But damn, did it feel good!

Day Eight-

	I'm starting to feel it! I tried to lift more than I could last week and was able to! The mass hasn't really shown yet, but I knew I was stronger. It felt amazing to do it, to lift even more! I couldn't help but notice I was getting more stares at me than when I started though. Men smiling at me and women giving me playful winks. I didn't know if that was just a thing that happened here, but I noticed them looking down at me. I don't know if they were admiring me or what, but it made me blush a bit to be noticed more. On a separate note, I noticed my shorts were tight and snug today. Usually they're a bit loose, but I didn't let it stop me from pumping iron!

Day Nine-

	I saw something pretty interesting today. Rogue brought a group of gals up to his private room for 'special training' I heard some of the other goers say. Wonder what the special training was that it had to be done privately. Probably something really intense to get the attention of the owner of the gym. 

	Gus helped me out today with my training a bit. I couldn't help but notice the feline got even fatter than a few days ago! How did he put on so much weight so fast? It didn't make sense considering he seemed to be at the gym a lot. Despite how fat he was, he could lift the weights like they were toothpicks! I was a bit baffled, but I just kept going. I needed to bulk up myself and get bigger!

	Before I left though, I did notice the women that Rogue brought to his room came out. They were drastically different! They were busty sure, but now their tits were utterly massive, their asses and hips were huge and wide. The lips on their faces were thick and plump. The biggest difference? They all had huge swollen bellies and were walking a bit bowlegged. Just what in the world kind of exercise did they do with Rogue?

Day Ten-

	Oh gosh, this is so embarrassing. Good news; I finally have some bulk and size on my body! I look nice and toned now and feel so good! The other news? I know why my shorts felt so snug. Somehow, my bulge got bigger! I was flexing in the mirror to see my size when I notice how prominent it was. My length is at least a foot long flaccid and my balls are like oranges! I was so shocked and stunned, but man, it made me feel good! I felt like a man! It made me want to breed badly...

Day Eleven-

	Ok, it has to be Hippo Thirst. There's no other explanation! Ever since I started drinking it, I kept drinking it. The more I do, the more I notice. My bulk has grown more since yesterday, but even worse was my bulge! I took a day off from the gym yesterday to relax, but in doing so, I drank tons of my Hippo Thirst. Even without going to the gym, I got bulkier and my bulge got bigger! It's the only explanation! Gods, just writing this is making me horny. My cock is huge, nearly as long as I am tall when erect! It's crazy how huge it is! I need to talk to Rogue about this. There's no way he doesn't know about this!

Day Twelve-

	I was ready to give Rogue a piece of my mind, but as soon as I got to the gym, he was there to talk to me! I was caught a bit off guard, but it was to say my membership got promoted! When I asked him promoted to what, he chuckled. “You'll see.” Was all he said as he handed me a special gold card with my name on it. It was to allow me to the elevator to the higher floors. I took it, still a bit mystified. I went to ask him what was at the higher floors, but before I could, the massive hippo was gone! How could someone so massive just vanish?! I was beginning to think there was something up with Globus Gym, but my throbbing cock said it needed more. Hard to argue with instincts.

Day Thirteen-

	Oh god. Oh god. Oh fuck! I knew it. Something was up with Globus Gym. But damn, it's a good fucking secret. I decided to use my VIP card and went to the first room today. I was not expecting what I saw. It was a large room with many walls and lots of corridors. Kinda weird for a gym until I noticed what was in the walls. All over them were asses and pussies jutting out of the walls with consoles near them. Every single one was a woman with the console telling you their name, who they were and with pictures of them. Men were all over, fucking them senseless. This wasn't a workout room, this was a breeding room for VIPs! The sights and smells instantly made my cock go erect, the massive fuckpillar engorging with need. I instantly caught the eye of several men as my length was even bigger than theirs, a few applauded. I watched a few cum into the women and pull out. As soon as they did, the bodies disappeared into the wall and were replaced quickly with new ones. “Don't worry; these sluts want this. Go ahead and use them~” I turned to see Rogue right next to me, plowing some woman's cunt senselessly! When did he get there?! How long had he been there?! I didn't ask. My mind was too consumed with lust. Before I knew it, I was fucking some bear woman's pussy relentlessly, the years of sexual frustration being let out.

Day Fourteen-

	Holy fuck. I lost count. How many women did I fuck into oblivion? How many cunts did I fill? I lost count. It was too much. I couldn't handle it and went into a frenzy. Rogue told me when I woke up that my production alone helped bump up Globus' stock by 4 percent; whatever that means. I was too exhausted and when I woke up, I was back home. Even after all the fucking I did yesterday, my massive cock needed more. I have never felt so needy and horny in all my life. I need more; I must have more!

Day Fifteen-

	'Ladies: your new god~' Was plastered over the photo I put on social media. It was hard not to brag when you're a four foot tall rodent with a six foot long cock and balls big enough to make even the biggest mammals jealous. Fuck clothes; I stopped caring about them. I was too big and too manly to care about such things. It felt good. It felt powerful! Walking down the street, cockslapping men out of my way and making women wet themselves at the sight of me. It was too fucking good! After all, who wants to stop a rodent smaller than them, but with four times the bulk they have? I'm a powerhouse and I need more!

Day Sixteen-

	Only getting bigger baby! Feels good! But there's one other thing I now know about Hippo Thirst. Yes it changes the person drinking it, but it changes them into their desires! Gus and I have both been drinking Hippo Thirst, but the changes for us have been different. Both of use got bulk, sure, but he got fatter and thicker. My thought was only confirmed as I saw him today. Gus wasn't a feline anymore. No, his fur was gone and his skin completely smooth as he had changed into a hippo himself! I was shocked and surprised, but maybe not too much. With how much had been going on, it was hard not to be too surprised. What did surprise me was when Gus pulled down his shorts and begged me to fuck him; right in the middle of the gym! I looked around, nervous at first, but no one made a second glance. Even on the regular floors, sex seemed ok. It wasn't as common as the VIP floors, but it still happened I guess. Man, he screamed like a fucking whore for hours before I made him my bitch.

Day Seventeen-

	Looks like my hypothesis was correct in that Hippo Thirst molds you to your desires. I was four feet yesterday, drank a few gallons of Hippo Thirst and went to bed, imagining myself to be taller. I'm now fucking nine feet tall! Holy fuck yes. I AM a god now! You don't know how good it felt to parade myself into the gym, my massive cock throbbing with need and my huge balls aching for release. All eyes were on me and I fucking loved it. Even Rogue was impressed with my size and gains, my body oozing testosterone and size. “Looks like you're ready for the next upgrade~' The hippo said to me as he handed me a blue speedo. I was a bit surprised cuz it seemed too small for me, but I took it anyways. 

Day Eighteen-

	I learned why the speedo was an upgrade. As long as I wore it, my massive bulge was somehow contained and shrunk to look a little more normal. I don't know how it did it, but it worked. Will make walking the streets a little easier. Don't need to dick slap guys across the street just to go down the sidewalk. That only proposed a new question to me: How hung was Rogue? He wore the same kind of speedo, so surely he must be rather hung too. The thought sent a huge throb through my length, my hand patting my bulge. Seems like I needed to breed another dozen sluts again today~

Day Nineteen-

	Figured it was time to try another VIP room. This one was less sex and more worship. Men or women members sit down in large comfortable seats as other smaller sluts tend to their needs. Sure, there was still sex and breeding, but it felt good to relax, drink more Hippo Thirst to get bigger and let myself be pampered. I saw Gus got promoted to Hippo Slut Server there. A suitable role for him. The new hippo had a massive ass, perfect for fucking. Made sure to have my way with him a few times for sure. Can't ever pass up on fucking a good hippo ass~

Day Twenty-

	Well, I had to find a new home to live in. When you're ten feet tall, a six foot doorway is hard to get through. Not to mention my bulk has only gotten bigger and bigger. That was alright though; Rogue has everything thought out. There's a housing complex right next to the gym for people of massive size. The doorways are still six feet tall, but stretch and fit around the person entering it and the insides are massive! It's like some weird hammerspace or something. I didn't mind it though. I could get to the gym in a minute rather than thirty now with how close I lived. Going to make sure to have a good time tonight to celebrate~

Day Twenty One-

	Fucking hangover. My head is pounding like hell. God fuck. I woke up, bigger than before of course. However, I might have went a tad overboard. Anyone else party so hard, they marry seven women and bloat their cunts out into oblivion? No? Just me? Fuck. Well, guess my life is going to get a bit hectic, but damn. I woke up and my cock felt fucking amazing. I guess I had gotten my uses out of them, their bellies so massive they were bigger than they were! I don't know how they could take so much and not just explode, but I didn't question it. My life had already gone so backwards and the whole month wasn't even over yet! My body ached and groaned. I needed more.

Day Twenty Two-

	So, guess who has two cocks and about a dozen more wives now? That's fucking right~ Your curious mouse stud got a bit curious. Hippo Thirst changed you to your desires right? Well, seems like it can even do crazy shit like growing you another fucking massive cock! Now I got two fucking cum cannons to utterly obliterate wombs with~ The best part? My wives are so obedient and lovely, they offered to take care of all of my kids without me having to do anything! Talk about obedience~ I could get used to this life~

Day Twenty Three-

	You know those video games with the characters that have multiple arms and stuff? Yeah, your god has more arms now~ I know right, fucking crazy! Massive muscles and six arms! I'm a walking legend and it feel so good! No one questions my size or arms either. I walk around, towering over everyone and they act like it's normal! It's so fucking great to just be the fucking best! Women from all over the city have been flocking to me, begging to be fucked by my cocks. They know they need a superior man to breed them and I'm more than happy to give them a mind shattering litter for them to raise~

Day Twenty Four-

	Hippo Thirst is literally the gift that keeps on giving. If it can give me more cocks and arms, I decided to try and get more technical with it. I tried having it alter my musk this time. I didn't really notice anything, but I notice it did exactly what I wanted it to do. I walked into an old coffee shop I used to frequent a lot. It's run by a polar bear lady named Patricia. I've lusted for her for years. Massive tits, huge ass and he pussy always smelt like it needed to be drilled. Today was the day~

	“Roland? Is that you?!” the polar bear said, completely surprised by my new size.

	“It sure is bitch~ You like?” I asked, flexing my massive body for her. Without waiting, I lifted up- my huge bulge and set it down on her counter top, the size still huge despite being shrunk down.

	“Wow! You look amazing! And...smell amazing too~” She said as she caught a whiff of my musk. She leaned in and smelt my huge bulge, moaning out roughly. She grunted and moaned out as he hand instantly went to her belly. Her pudge gurgled before it began swelling and rounding out. That's right bitch~ My musk is so strong, you'll get pregnant just from smelling it!

	“Such a good slut~ You like Daddy's musk?” I said petting her head a bit.

	“Oh yes! It smells so good Daddy!” The polar bear said back, her belly getting bigger and bigger. Soon, it was big enough that it lifted her body and fat ass off the ground.

	“That's nice slut, but you need to change more. Become a proper whore for Daddy~” I simply said to her as Patricia moaned out, her body grumbling more. Soon, her tits and ass exploded out in size, utterly consuming the bar and counter near her. Her moaning got muffled as the lips on her face grew out massively, her plush facefuckers consuming her face. The sight of it made me grind and chuckle roughly. “Good whore~ now; birth!”

	As soon as I commanded it, she yelped out as best she could through her massive lips. The crotch of her pants bulge out heavily as something began pushing out from her, forcing it's way out. Soon enough, her pants and underwear tore as a beefy hung rat forced its way out of her. He looked almost like a clone of me, making me smirk more. She'd only breed sons for me and we'd breed this fucking city. “Good whore~ now, don't stop birthing. It's your new role in life.” The polar bear could only scream out as another rat began pushing it's way out of her swollen belly as I left, her womb never going to stop birthing for me unless I commanded it to.

Day Twenty Five-

	Mice rule, everything else; too bad~ Everything with two legs that could move were getting fucked by me and my sons. Hippo Thirst even made it possible for men to get bred by us! Is there anything this drink can't fucking do?! The city was quickly becoming a fuckfest. Everything that wasn't a mouse was getting bred to high heavens, forced to birth more for us. Of course, I couldn't let that fly. Mice are superior so EVERYONE had to be a mice. And I knew just how to do it~

Day Twenty Six-

	And I did it. Everyone is a mouse now~ Only took a little more altering to my musk and fucking to make me and my sons convert anything they fucked into a mouse. Now, we are many! We rule this city! God, it feels so fucking good to be the king! I converted Gus and Patricia to be my god breeders. The dumb sluts pump out mice by the seconds and just let them loose to fuck and terrorize. Everything wants to serve me and my needs. I lead this city and it';s breeding frenzy. Of course, there would be one loose end. I got a letter from Rogue; a platinum membership card. Seems like there was still one slut I needed to break~

Day Twenty Seven-

	Breeding and converting the hippo should've been easy. One smell of my musk should've corrupted him and enslaved him to my will. Yet, the massive six armed massively hung god was now split upon the hippo's cock. His length was unlike anything I could've imagined. His length is literally skyscraper incarnate and then some. I couldn't control myself. I submitted in seconds and before I knew it, I was his toy; his length ruining me.

Day Twenty Eight-

	Ah, I knew I'd find it! This is Rogue for those wondering~ Seems like Roland here couldn't contain the power I had given him. It's a shame that mortals submit so easily to power and crave more. I simply wanted to give him what he wanted, but he took too much. It's a good thing Hippo Thirst has plus sides. It's made with a mixture of my cum and magic so if anything gets too extreme, I can always stop it from happening. Roland's mind is less aggressive than it was before now that I've calmed him. He makes for an excellent cocksleeve if anyone wants to give him a try~ In any case, I plan on getting things back to normal around her, but spreading his influence to the whole city helps~ Now I have connection to anyone in the city for my own fun~

Day Twenty Nine-

	What happened? Mind mind is so hazy. One second I was entering Globus gym for the first time and now I'm back home in my old apartment. I feel like something big happened, but I can't quite put my finger on it. I rolled out of bed, grunting as my thick fat ass wobbled about. Wait. Fat? I don't think I was fat before...Must just be the hangover? I any case, I should get my fat hippo ass out of bed and get down to the gym. I have plenty of gains to still get!

Day Thirty-

	And the month is done! Whew, it took a lot of effort, but I think I have my ideal body now. An eight foot tall hippo, 950 pounds and with a nice bulge in between my legs~ A lot of the guys give me looks though. Most of my fat is at my ass, see, so plenty of them get some big boners looking at me. Especially the owner, Rogue! Every time he sees me, his smile gets wider. It's like he knows I want him to fuck my ass or something! Oh, he's calling me over now! I do have his platinum membership card, so is he calling me up to his room for special training?! Oh god, this is so exciting! I wonder what kind of training it is!
