A pair of newlyweds stopped a van in front of an empty house. On the back of their red van, there was writing in white that said 'V & G.' with a big heart sign enveloping it.
A man with the beginnings of a beard stepped out of the van. "Well, this is the place." He announced. "Home sweet home, Velma."

A woman in an orange sweater stepped out of the passenger door and looked at the white house. "This is the place? It looks a little...rundown, Greg."

"It just needs some T L C and it'll look as good as new." Greg announced. He opened up the backseat and pulled out a box. "Come on, let's get our stuff inside."

"T L C? This place is so rundown that I'm convinced we're paying the spiders rent." Velma grabbed another large box. The pair only brought the essentials plus some entertainment, so there wasn't much to unload.

"It doesn't look 'that' bad." Greg opened up the door and stepped inside.

"Someone boarded up one of the windows, the grass is up to my knees, and the paint is peeling. I think part of the roof is missing too." Velma said in defense with a roll of her eyes.

"The previous owners were pretty lazy." Greg replied. "We'll take care of it one day at a time. It'll cost a bit to repair, but we should be thankful we have a roof over our heads to begin with!"

Velma sighed. As she stepped into the house, she felt a shiver. She couldn't explain it, but it felt almost as if there was another presence there besides the two of them. "They left, right? Like, no mysterious deaths or anything?"

"None that I'm aware of." Greg set the box down in an empty living room and turned to Velma. His shirt tore as he turned. "Ah dammit. That's the third shirt this week!"

"Yeah, ever since you've come into this house like five days ago to check it out, you've been changing." Velma set down her box.

"Changing how so? Emotionally? I'm just excited! Two twenty year olds free to do what they want!"

"You've been getting fatter and I can tell you've been masturbating a hell of a lot more." Velma said with a concerned look. "Like, unnaturally fatter. Have you thought about seeing a doctor?"

Greg rolled his eyes. He pulled out a candy bar he set in his pocket and took a bite out of it. "Look, I gained a few pounds, but that shouldn't matter. We have our new lives to live here! Come on, help me unpack, and then we can celebrate our independence."

The two unloaded their small van. As they unloaded, Velma felt a growing need between her legs. She couldn't explain it, but Greg was turning her on while just unloading the van. Greg's weight gain of at least 50 pounds and his sudden slobby behavior was a turn off for her before, but now she began to feel an arousal for him. Velma caught an erection between Greg's legs as they unloaded two trash bags full of clothes. She wondered maybe that she could have some fun with him to celebrate. After all, they were free to do as they pleased.

Greg set the final box down, and then turned to Velma. Greg felt exhausted, moreso than he swore he should have been from unloading the boxes. Moving was a workout, but he felt winded. "Okay...well with all the boxes in here, let's take five."

Velma dropped the last box and breathed heavily. "No...no argument here." On top of feeling exhausted, she felt hornier than ever. She could tell Greg felt the same way. With a smile, she walked over to him. "Perhaps we can take five in the bedroom?"

Greg grabbed Velma's hand and grinned. "I never thought you'd ask." He brought her up to the bedroom for a round of fun.

One round of sex later, Velma and Greg laid on the bed with the blanket underneath them. Both of them laid naked and sweating. Velma spread her arms and legs with a smile and looked to Greg. "That...that was amazing." Despite how recent the sex was, she wanted more. However, her body was exhausted.

Greg's cock was flaccid, but it was wet with cum from the recent orgasm. He couldn't even remember the sex with how intense it was. He just knew it was wonderful. "We should...we should do that more often."

Velma couldn't help but agree. That first round of sex went by so fast and it was so intense that she could barely remember it. It was the most intense sex the couple ever had, although it felt a little plain. "I guess we have to start unpacking everything."

Greg groaned as he laid back in the bed. "Can't we just lay here and have more sex?"

Velma felt tempted to agree with Greg. Her body felt lazy and heavy. She looked down at her stomach and she swore she saw more of a gut than she did a few minutes ago. Uh...okay...later tonight, alright?" She pulled herself up with great difficultly. It felt as if she just woke up. She heard multiple light cracks in her body as she walked out of the room. She didn't even care she walked out naked. It was their house now after all, she should be able to wear whatever she wanted, or didn't want in this case. She walked to the bathroom, but paused in front of the mirror above the sink.

Velma could see her clit noticeably larger, and it looked and felt firm. She reached down and gave it a gentle touch, and then shivered. She felt a pulse coming from it, which was her own heartbeat. "Okay, calm down. So, you have a... you have a bigger clit than usual. No big deal." She also saw a pudginess to her belly that she knew she didn't have before. She looked almost as big as Greg did. 'Is this house making us both into fatties? No, that can't happen. Houses don't get cursed like that.' She thought.

Greg walked into the bathroom moments after and wrapped his arms around Velma from behind. He gave her a kiss, and then looked into the mirror. "Who's that young hottie in the mirror?" He teased.

Velma rolled her eyes. She could also tell there was something different about the pair. "Oh you. I'm..." She paused. She swore she was in her early 20s, but the age of 28 popped into mind, a number she knew she hadn't reached yet. "Heh...I think the sex was a little too intense. I feel out of it."

Greg nodded. "I know what you mean. It feels like we've been here for years." He looked down at the sink, and blinked rapidly. "Huh...did we unpack our bathroom stuff yet?"

Velma shook her head. "We just brought in all the boxes." She hated the idea of unpacking all of that furniture.

"Then why do we have it all there?" Greg pointed to their toothbrushes, toothpaste, combs, and various other bits of their bathroom supplies. The bathroom looked as if they already unpacked everything inside of it.

Velma scratched her head. "Huh...I don't know. Well, less shit to unpack then!" She left the bathroom and walked to the living room, only to find that everything was unpacked. She didn't unpacking anything, and she knew Greg didn't either. After all, the two were in the bedroom having raunchy sex. She remembered the sex and it made her clit feel hard and eager for more.

Greg followed behind Velma. He walked to his side and bumped his butt with hers. "Heh...looks like someone did all the hard work for us, right?"

Velma nodded. She stepped forward, and then heard a crunch noise. She glanced down and saw the remains of a candy wrapper. In fact, as Velma glanced around, she saw more than a few wrappers just thrown haphazardly onto the ground. "A bit messy though." Greg and Velma were not innocent of making messes, but the amount of wrappers on the floor seemed excessive, even for the slightly chubby duo.

"Ah we can pick it up later. Let's get back to more sex!" Greg gave Velma a hug and grinded his cock on her ass. "Maybe different kinds of sex too if you're up to it?"

Velma felt Greg's shaft, but the idea didn't feel nearly as appealing as it did a moment ago. She wanted sex, but something felt...different. "Ahn...hah...something doesn't feel quite right though. Like...everything's unpacked, we're both fatter, and we're not even trying to get clothed. Doesn't something feel off?"

Greg blushed. "I didn't want to say anything, but uh...well I'm sure you can tell what's going on with my cock...maybe."

Velma didn't want to say it, but she knew it. A man's cock was sacred, at least in terms of size. She knew Greg was getting smaller over time. She could feel it during their last round of sex. "Yeah." She replied casually. "Maybe we can try switching things up a little more though?" She offered. "Like, something totally different? Not anal, but something...um...how do I put this..." Velma casually reached underneath the small table next to her chair and pulled out a large black dildo. She wasn't even sure she 'had' a dildo there; she just pulled it out without even knowing its existence. "How about we try this?"

Greg identified as straight. The idea of a cock in him usually never excited him, but today it seemed to excite him more than before. He felt his cock twitch eagerly. "Well, I suppose if we're going to try all kinds of sex." He let out a grunt with a casual fart. "Ahn...yeah sure, why not?"

With a grin, Velma kissed Greg and put the strap on her. Once more, the two went to it, but this time with Velma on top and fucking Greg's ass.

As Velma pounded away with the dildo, she swore she could feel it more than she should have been able to, but it was far from a complaint. She also swore she felt other things. Unaware to her, Velma packed on pounds while she pounded Greg. Her clit continued to swell, and she could feel something growing deep inside of her, something that made her feel even more pleasure.

Greg's body also grew larger the more the two had sex. He enjoyed the fucking more than he thought he ever would. In fact, his orgasm came very quickly. He felt his cock pulse and pump his seed freely. As he came, his cock shrank down with each pulse and throb until his cock was half the size it once was.

Along with the two of them growing larger, they were also getting older. Their very surroundings changed, as if they lived in their new house for more than a few years. Their skin also changed to a sickly gray, though still human.

Velma laid on top of Greg and panted. She felt almost as if her very clit wanted to orgasm, but it couldn't. "That was...wow..." She said with a happy sigh. "This...it's so good."

Greg slowly nodded. "Two rounds of sex in such a short time." The sex was intense, but he wished there was more...he wasn't sure how to describe it. He wanted more of it. He pulled himself up, and his back popped multiple times. "Uhn...well, now what do we do?"

Velma's stomach rumbled as if to answer that question. "We worked pretty hard. Everything's unpacked. Heck...we don't have to do anything! Let's order some food for celebration of a moving well done!"

It felt almost as if they moved months, if not years ago. Greg knew they moved into the house, but as to 'when' felt like a foggy memory. Still, the two of them had money and quite a lot of money at that. They just spend the money on food whenever they got it. The amount of wrappers on the floor indicated as such. "Yeah...that works for me. Let's uh...dash the food, or whatever the shit you call it."

Velma ordered at least fifty dollars' worth of food for the duo. Once ordered, she pulled herself up and took off the dildo. She missed the feeling of the dildo, but once she removed it, she saw that her clit was at least half the size the dildo was. In fact, the clit looked far more like a cock. The inside of her cunt also felt full, as if something just wanted to push out of it. Unable to help herself, she reached down and split her nether lips apart slowly. The moment she did, two small testicles popped out and sealed her cunt, effectively changing her gender. The sensation felt so pleasurable that her new cock came, but with its small size, she only orgasmed a small amount. It still felt unbelievable to orgasm in a new method, and immensely enjoyable.

Greg on the other hand noticed his cock was much smaller. He couldn't see it underneath all of his fat, but he could feel it. He knew he should have been worried about his even smaller cock, but it was hard to feel concerned, especially when he felt so horny. The way the two of them fucked not an hour ago, felt as if it was the most intense and pleasurable sex they ever had. Greg almost wished the cock was real and Greg would get a cunt. Then, the two could fuck and have fun all night.

'God. How many times have we felt each other already?' Velma thought to himself. He could no longer feel his cunt, but his balls and cock were just as sensitive as his cunt once was. He couldn't get his hand away from his shaft while he walked around the house, as if to inspect the place. The house smelled of food, sex, and sweat. He didn't get to walk around very much before he felt winded and had to sit down on the couch. "Uhn." He put his feet up, and then looked down at his body. "I look like I'm in my damn thirties."

Greg walked into the living room and sat down next to Velma. Her fat arms brushed up against Velma's own. She turned to Greg with a faint smile. "So, we're uh...you can tell things are different, can't you?"

Velma nodded. "Yeah, but..." He wiggled his rear and sighed. His body felt sweaty, but he didn't care. "I'm just sorta..." He shrugged. "Eh, it's fine." He kept one hand on his cock.

Where Velma couldn't get his hands off his cock, Greg couldn't get her hands out of her cunt. "Yeah. Like, we're transforming, but...whatever." Greg shrugged.

"We should really be more worried about this." Velma shifted in his seat and let out a casual fart. He picked up the scent of their body odor, but it didn't disturb her nearly as much as it should. "I think I'm going to go shower." He took his hand off his cock and put it on the couch to help push him up. He either didn't notice, or care that his hand had cum on it, and that seed transferred to the couch.

Greg watched Velma walked away. She couldn't take her eyes off Velma's flabby ass. She noticed a slim tail, but she didn't let it bother her. She kept fingering herself freely on the couch while she looked at their channel selections. They already had 'favorites' marked, and all of them were pornography related channels.

Velma stepped back into the bathroom and looked at the shower, and then at the tub. The shower and the tub were separate from each other. The shower was small, but the tub was almost as large as a hot tub was. He was already quite thick, and the shower didn't look very large. He squeezed himself into the shower and started it up. He figured that if he couldn't clean himself in the shower fully, he'd just swap to the tub. "We're definitely different." Velma said as he stepped into the shower. "Our genders are different, but...god I just feel too lazy to do something." He started up the hot water and felt the drops rush over his body. "Is that part of the transformation, or whatever, that's going on too? Ugh, it probably is. Fuck..." Velma paused at the word fuck. The word alone felt so good.

Greg kept her hand in her cunt and continued to play with herself freely. She grabbed a large bag of snacks near the couch and ate with her other hand as she watched television. She let out a deep belch, and patted her stomach. "Hm. I need a drink with this food, but I don't want to have to get up." She groaned. "Uhn, I'd kill to..." She paused. She looked over the couch and noticed a miniature fridge. She opened it up and found soda cans. With a huge grin, she helped herself to soda. She never remembered either of them having a miniature fridge, but she didn't worry about it. With each orgasm she experienced from playing with herself, she felt herself care less and less.

Velma was a bit more concerned than Greg was, although he couldn't get his hands off his new cock. His cock had a quick orgasm in the shower, though his seed washed away in the running water. "Ahn...uhn." He noticed an unpleasant smell pick up in the shower during his orgasm, and he quickly realized it was coming from him. He figured it was a good thing he decided to shower! 
Despite a recent orgasm though, his cock was still semi-hard, and he couldn't keep his hands off it. "We're...we're turning into damn slobs. Maybe that salesman was right." He paused. "Wait, I never talked to him. Why would I even...ahn." His body thrust forward slightly as he felt a surge of pleasure. "Dammit."

Meanwhile Greg's body was more hide than skin. She pulled her fingers briefly from her cunt and bag of chips to look at them. One hand was soaked, while the other had orange dust covering it. She thought about swapping hands briefly, and the idea made her laugh. She knew she shouldn't be so lazy or sloppy, but it was hard to think about anything else except sex, eating, and sleeping. "What kind of jobs...ahn...do we even do now?" She doubted she worked at all, not that it worried her.

Velma got out of the shower and dried himself off. He glanced in the mirror and noticed just how much his body changed. He knew he was a male, and he knew he was fatter, but he didn't realize how hippo-like he looked until he saw his reflection. He couldn't believe it. His feet were massive hippo feet, and he never noticed it because his fat gut was in the way. He swore he looked older too, but he couldn't pinpoint by how much. He waddled out to the living room "Greg! Do you see what we're becoming?"

Greg let out a deep belch. She swapped hands as she ate her chips, but she didn't care where she got crumbs on her. She turned to Velma and tilted her head. "Huh? Yeah. We're uh...something about fat lazy asses, right? Want to have sex?"

Velma stared at Greg's body. Greg was just as fat as he was, except unlike Velma, Greg now had E tits, likely larger thanks to the fat she had. Velma used to have tits, but they were now what one would call 'moobs', man boobs. "I..." It was hard to say no to that question. Even though Velma orgasmed recently, he was hard again. It was difficult to keep control of himself when he was constantly horny. "We're becoming lazy fat ass hippos. We've got to get out of the house!"

Greg groaned. "Do I have to?" She wasn't sure how many orgasms she had, likely more than Velma did. Her cunt looked red from how much she toyed with it, yet the sensitivity hadn't decreased, though the size most certainly had. "Can't we just sit and fuck all day? Who cares what we're becoming?"

Velma groaned. He quickly knew he wasn't going to get help from Greg, but as he let out a fart, his legs wobbled. His heart pounded with adrenaline, but he felt lazy at the same time. "Well, what about our old lives?"

"Fuck if I remember anything about that. I remember school was terrible because I was fat and teased. My self-esteem took a hit, but unemployment helps pay a good portion of the bills while streaming our sex fun helps pay for the rest!" Greg said happily. Her voice sounded more feminine, but a deep feminine that went along perfectly with her massive fat body. "They called me the fat friend and said I'd never get married, but look at us now!"

Velma knew that wasn't true about Greg's life. At least, from what Greg normally told him it wasn't. He tried to think, but his hand continued to stroke his cock idly. He didn't have to think about it for his hand to masturbate. "Okay, fine. Stay here. I'm going." He turned and walked to the door. "I'm going to find a way to fix us."

"Aw, you don't have to go to that kind of effort." Greg laid on the couch and spread her legs. "Come on. One round of sex before you leave. It couldn't hurt, could it?" She let out another shameless fart.

Velma turned to Greg. The two were becoming fat gassy hippos, and possibly something more that she couldn't quite place his finger on. The moment he turned to Greg though, he saw that cunt, and signs of pubic hair on it too. His jaw dropped as he saw that red cunt. His cock throbbed with need, the same cock he kept rubbing. "Ugh...stop. Don't tempt me."

Greg giggled. "It's sort of my job to tempt you. I'm your wife." She held up her ring. "Don't you remember? Now, come fuck your wife. I don't know if I'm pregnant with how fat I am, but I don't care. Knock me up if that's your kink."

Velma slowly turned around and walked over to Greg. "Fuck..." He couldn't help himself. He pounced on top of Greg and felt her sweaty hide covered body against his own. He pushed down and slid his cock up again, not in Greg's cunt, but in her fat. "Ahn!"

Greg giggled. "I don't think that's my cunt, but if that's what you want to fuck? I'm not going to stop you, my dear husband."

Velma felt humiliated. His cock wasn't in Greg's cunt, but in Greg's own belly fat, and it turned him on even more! He could only imagine it turned Greg on just the same. Fat sex was a kind of sex he'd never imagined doing, let alone so aroused. "I can't...I...ahn!"

"It's okay, you're a premature ejaculator, we know that, but you get hard fast all the time anyways. You cum, but then you'll be ready in a few minutes to cum again." Greg giggled. "It's a good trait when you can orgasm so much!"

Velma knew that shouldn't be true, but he couldn't think about it any other way. Greg's fat was so warm and it folded so perfectly around his cock that it was as if they did this on a regular basis. Unable to help himself, he moaned and came. His seed splattered all over Greg and Velma's stomach. As he came, he felt winded as it felt as if someone took years from him, and Greg. The two grew wrinkles along their gray hippo bodies. Laugh lines and crow's feet developed on their faces. They weren't old, but they were definitely beyond their 30s.

Greg orgasmed as Velma came in her belly fat. She loved feeling her husband's orgasms, no matter where they were on her body. Her snout pushed out into a short hippo one and she looked just like a massive fat hippo anthro woman. "Oh! Fuck that was good! Come on, fuck my cunt next!"

"H-huh?" Velma pulled his cock back. He felt his shaft slide against the thick, slick folds that was Greg's belly fat. He felt humiliated what he just did, but so aroused. He just knew Greg loved it as well. "But what about a shower?"

"We don't need a shower." Greg said dismissively. "Just let the cum dry out, it'll be fine. Come on, fuck my cunt next! I've needed you all day, beautiful!" She hugged Velma as best as she could with her fat arms. The two of them probably weighed more than four hundred pounds, and that was separate. They had to get special furniture that could contain their huge weights and desires for so much sex, but even then, most furniture ended up breaking after huge orgasms.

Velma could tell Greg was in too deep. He wanted the two of them to fight it together, but there was just no way. He looked back to the door and pulled back from Greg. "I...I'll be right back! I think a package arrived." He had to think of something to get them apart for a few minutes.

"Remember to use the grabbing stick. We're too fat to get out the door, member?" Greg rubbed her hand along her gut where Velma came and began to finger herself, sticking Velma's seed in her cunt without a care.

Velma opened up the door completely naked. His gut covered most of his cock at this point anyways. He also felt winded just going to the door. He opened it up and saw there actually were packages waiting! He realized that of course there must be, they were too fat to leave the house so they just ordered everything for delivery. He tried to get out the door and ignored Greg's warning, but his fat ass and gut caught up in the doorframe. "Shit." He quickly realized it'd be impossible to fit through and pulled back before his fat ass was stuck in the frame. It was then he remembered a time when Greg realized she couldn't leave. Greg's ass was stuck in the doorframe, Velma fucked her from behind for days, and Greg loved it.

Velma grabbed the packages with a crowbar, or as Greg called it, the grabbing stick. He opened one of them up and saw a large dildo. "Sex toys? Are these needed?" He asked, but not loudly.

"Of course! You can't fuck my cunt and ass at the same time, and there are times I got to take a piss!" Greg shouted from the living room. "So I need cocks, and you need an onahole! Onohole? Whatever the fuck they call those things."

Velma never knew Greg to be so vulgar. "They better not be bigger than me." He shouted back, and realized exactly what he said. "Oh shit. Greg, we really have to do...uh...something." He lost more and more of his old self the more he tried to think about what he used to be, and why he wanted to run out of the house in the first place. He couldn't even run anymore. Walking was even a challenge for the fat hippo; some might call him a 'DILF' at this point.

"Oh hun, you know no sex toy, hand, wrapper, or anything for that matter can replace you." Greg called out with a belch. "Now, how about that sex? Unless you want to fuck my fat again."

Velma was very tempted to want to fuck Greg's fat again. He felt his cock leaking seed just from the thought. He remembered himself masturbating and having so many orgasms that his body grew adjusted to it. He 'had' to cum regularly. Some would consider it a problem to need to orgasm so much, but not Velma or Greg. It was a blessing to need to orgasm so often for the couple, it just meant they could have that much more sex. "I...I shouldn't." Velma said quietly as he walked back to the living room. All the couple did was eat, sleep, and masturbate, or have sex. They'd often do it in front of a webcam. Two massive hippo slobs having sex in all sorts of kinky ways made big money online, and they were more than happy to do what they usually did for money. It was the lazy way out.

"You should though! You member what the doctor said! You only orgasmed what, two times? You got to do it at least three times in an hour to prevent your blue balls, now come on, Vance. Fuck me good! You're always the one asking ME for sex!"

Vance? Yes, Vance was his name, not Velma. Just like his husband's name was Grace, not Greg or Gary or whatever Vance thought her name was. The name 'Grace' ironic being she was anything 'but' graceful. "Ugh." He got on top of Grace. "The doctor also said if I can restrain myself then I won't need to cum so much."

"But we WANT you to cum a lot! We decided that. Don't you remember? You're my big slobby husband." Grace kissed Vance on the lips, and deeply at that. She still had some food on her lips, but she didn't care.

During the kiss, something clicked in Vance's head, something that reminded him that they did agree on that. He kissed back lovingly with a growing smile on his face. There was still something worrying him, but he could concern himself with that later. For now, he was horny and he had to cum, and he'd do it with his wife.

The two spent the next few hours fucking and having fun as two big slobby hippos, both well in their 40s. As they mated, they both quickly forgot their past lives and instead remembered only their new ones with some drawbacks, but they always had each other for company, pleasure, and food.
