The Griffin household was surprisingly quiet during the daytime. Meg and Chris had school, and Peter was out seeing where he could buy 'beer battered donuts' after seeing them online. Lois was with her mother and father, trying to help 'rekindle' that old flame, although without Peter, it was going better in some ways, and worse in others. That just left Brian and Stewie home. Of course leaving a dog and a baby home alone was never a good idea, but it was Peter's idea to begin with of course.

Brian sat on the couch wearing what he normally wore- little more than a fur coat and red collar. He watched a show called "Two Broken Girls" which showed two women that wore a yellow waitress uniform with a red apron, but they lay on the ground with all of their bones broken and tangled up in a mess- their joints bent where they shouldn't be, and each of them screaming in pain before they both shouted "Mexico!" then and there.

Just as the show went to a commercial, Stewie entered the living room. He turned to the television, and he said "What in the hell is this garbage?" before he picked up the remote and tossed it at the television. The remote went through the screen and shattered it. The television turned off right then and there, with a bit of smoke.

"Oh great. What's your problem today? Did Peter give you beer instead of milk again?" Brian scoffed with a roll of his eyes. Stewie had been in this mood ever since Lois left to help out her parents.

Stewie turned right to Brian and, with a pair of fists at his sides he said defensively. "No!" and after a short pause. "He put Coke in my Cheerios. You don't put Coke in Cheerio's, Brian. But that's not it. Lois hasn't been around at all for me to try to kill!"

Brian got up off the couch. "Wow. When was the last time you actually tried to do that?"

Stewie's angry expression changed to that of disinterest and he merely shrugged. "I-I don't know I just need some motivation to...to want her without actually saying I miss her." He spoke quickly and quietly, before his tone returned to that of a more normal voice. "Anyways, I have an invention to transform someone to both look and act just like her, and I want you to be that one to become Lois, at least until she comes home."

Brian rolled his eyes at that. "Yeah, right. You just said it- you want her around to try to kill her; you're just going to try to kill me in her place." He actually didn't sound all too surprised at his invention. Of course, this was the same Stewie that made time travel and multiverse travel possible, amongst other things.

"I promise I won't kill you Brian." Stewie replied with his eyes half lowered. "You have my word." He paused for a brief moment before he added. "You also get to see her uh...I don't know, you get to see and feel her without clothes on. That's a thing for you isn't it?"

Brian grinned at the idea- that short tail of his wagged wildly too. "Let's do it." He didn't need any other motivation. Seeing Lois naked was one thing, but to BE Lois naked, and explore her body so thoroughly was a dream come true for him.

A short time later, Brian and Stewie were in Stewie's room. Stewie pulled out what looked like a small gun. The gun was filled with a blue liquid that glowed through a see-through opening at the top. The area where a gun would shoot was largely sealed, except it had two tiny holes instead of one large one. "I took Lois's DNA and built this machine. You'll get a small injection that will modify your DNA to become hers, thereby changing into her physically."

Brian glanced down at the odd weapon- hidden underneath the crib, as Stewie often hid such things. "Really? It's all ready just like that? We don't have to do anything extra? No special adventures of needing to travel inside Lois or anything?"

Stewie rolled his eyes and scoffed. "Come on Brian. Just because the two of us are together and I have an invention doesn't HAVE to turn into some super adventure. Even the people in Back to the Future get a day off adventure once and awhile."

There was a brief scene switch- something the show was infamous at doing. The new scene revealed Marty McFly sitting at home on a blue recliner reading a magazine about 'the future of skateboarding' when the phone nearby him rang. Marty picked it up eagerly and, over the phone, he heard Doc Brown's voice. "Marty, you've got to come back with me!" Marty's eyes lit up and a grin appeared on his face. "Back to the future, Doc?" "No, back to the grocery store- I forgot the milk!" Marty's face quickly turned into a frown. "Oh. Okay, Doc." With that, Marty hung up the phone, sighed heavily, and left the living room.

Back to Brian and Stewie...

Brian simply shrugged his shoulders down at Stewie. "Alright, not going to complain- let's get this started and Lois-ify me!"

"On the condition that you never say Lois-ify again, deal." Stewie replied with an annoyed look. He quickly put the gun-like device on Brian's arm and pressed the trigger. The blue liquid in the device shot straight into Brian's arm, and Stewie pulled the device away when it was done. "Now, it will take some time. Luckily everyone's out of the house, so just...I don't know...go back to doing what you were doing, and you'll become her before the day is done."

Brian winced at the device into that arm of his- or well, his front leg, whatever one might call it. It didn't hurt, but he was expecting it to. Surprisingly though, it was all done just like that. "Really? That's pretty simple. What do you think will happen first? Will I get her chest? Her uh...her hair? What about her..." he didn't want to say it in front of Stewie, but considering Brian's train of thought- it was pretty obvious what he was thinking of.

Stewie didn't get the message of how obvious it was. "Toes, yes, they're very fun sometimes I know. You'll become exactly like her and get everything she has. In truth, I haven't exactly tested the device yet, so I'm not sure how long it will take. Just keep yourself properly censored for the network when the changes happen, and you'll be fine."

"Network?" Brian raised a brow at that. "But we're not on the air. We're in...what would you even call this...we're in what they call fanfics."

"Oh." Stewie turned away from him- it looked almost as if he were trying to peer through whatever was looking at him, and look at whatever was seeing Stewie, right back at them. He turned back to Brian a moment later, and shrugged. "Alright, go nuts then. Just don't turn this into some weird 'Brian X 'Lois' thing."

"How could I even do that? Lois isn't going to be here anyways, that's why we're doing this in the first place. If this would be ANYTHING, this would be a Brian X Stewie, and I'm pretty sure neither of us want that." Brian said with a scoff and an eye roll. He'd look around at himself briefly, but he didn't notice any significant changes. Even where he first got the odd device put in didn't look any different.

"Yeah I'm not going to go into how wrong that sounds." Stewie's tone was normal, but with his eyes half lowered, the thought clearly disgusted him. "Granted you're a dog, you do some pretty gross things anyways."

"This is coming from a baby who continues to crap in their diaper." Brian turned around, and walked to the door. "Besides, you haven't seen the internet. I'm pretty sure there are some Brian X Stewie stories out there anyways if you look around on the internet for five minutes."

As Brian left Stewie's bedroom, a moment later those floppy ears of his could pick up Stewie's voice. "Oh my god it's awful! There's no 'Q' in 'Stewie', and what the hell is this Stewie doing with peanut butter?! Why in god's name does this even exist? And what's Rule 34? OH GOD WHY IS THAT A RULE?!"

Brian couldn't help but chuckle to himself as he went back downstairs to watch television. "I didn't even think he had a computer in that room, but I'm not going to question it."

Some time later...

With the television broken, Brian went out of the house to get some kind of entertainment. Meg and Chris had just returned home from school, so Brian gave them the job of taking care of Stewie while Brian was out. Brian decided to go to the park today. He helped himself to a bench, and glanced around. It was a bright sunny day, but there weren't too many people in the park. Brian was more focused on those passing by. It had been some time since he had tried to find another girl, so he figured now was as good a time as any, at least before he turned into Lois. And maybe after he became Lois, he could still be with that girl. The mere thought of that excited him enough to make that stubby white tail wag.

Brian didn't have to wait long. A thin blonde girl walked along the path in front of the bench. She had at least B cups, as well as a pink tank top and blue shorts. She had earphones on, and she just walked along, listening to the music. Those blue eyes of hers blinked, and her ruby red lips hummed some of the lyrics of what she listened to.

Brian knew only one thing about this girl right off the bat- a taste for music. He tapped her shoulder when she got close enough, and he gave off a smile. "Hi there- I hate to interrupt, but I'm a big fan of music too, what are you listening to?"

"Hrm?" The woman turned to Brian and took out one earphone. She picked up what he said, but even if he did like music, there was one glaring question. "Why aren't you listening to anything then?" her voice was as smooth as butter, and fairly high pitched as well.

"I ah..." Brian had to think fast about that. "I like to spread the joy of music to all the kids around the world, there was this really thin orphan I met on the way here, so I gave it to him."

"Aw, that's so sweet." The girl smiled down at him. "I'm listening to Taylor Swift, she's really good- have you heard of her?"

"Heard of her? I love her- but maybe we can talk about her perhaps...over coffee?" Brian wanted to be more straightforward than he had ever been today. Sure, he knew he was going to become Lois, but that didn't mean he couldn't have some fun first.

The girl smirked down at him. "I'm not a huge fan of coffee. I do like some-" before the girl could finish, Brian let loose a fart right then and there. "I...just remembered I have to go do something, away from here." The girl then jogged off.

"O-oh what? Misses perfect never farts? I'm sorry; I didn't realize your name was Mary Sue!" Brian scoffed, and sat right back down on that bench, so what if he farted? It was a normal thing to do, yet one lone fart made that girl run away. "Maybe the park isn't the best place for women anymore." He hopped off that bench and decided to try elsewhere. Before he got too far, his stomach rumbled, not with gas, but with hunger. Luckily, there was a hot dog vendor with a cart located right at the exit of the park. "Huh. That's convenient, it's almost like they knew I was hungry."

The scene briefly switched to that of a large gray room filled with various hot dog, hamburger, and ice cream vendors, each of them with a small cart. Above them in a tiny building was a small bald man watching a green computer screen. A dot appeared on the screen and flashed red before the man shouted over the microphone "Got a hungry one at 120th and Central-move it people!" A large gate quickly opened up, and the vendors flooded out of the gate.

The scene then switched back to The Drunken Clam where Brian sat on a bar stool with a beer in one hand, or paw as it may be. Next to that beer can was another two cans of beer toppled onto their side and emptied. On the other side of Brian was a half plate of nachos, Brian's lips were covered with orange cheese. His belly also jutted out quite a bit in front of him, a few inches shy of how far his muzzle stuck out. "Ten hot dogs, a bunch of beer, nachos, and soon I'll be able to personally play with 'Lois', I'm as happy as a clam."

"Speak for yourself." A voice spoke- when the one that spoke came in to view, it was a giant clam that sat right next to Brian, with a large glass beer right in front of him. "My day's been a real clamity."

Brian looked at that clam and he was...really unsure what to say. Maybe an unhappy clam was where the bar got its name from? He didn't focus on that clam for very long though as he noticed a woman entering the bar. This woman was a bit chubbier than before, she looked like she was in her 30s. She had a B cup set chest, short brown hair, and she wore a V-neck shirt with dark blue jeans and high heels, and she was walking towards Brian. She wasn't paying too much attention though; she was texting someone on her phone while she walked.

Brian knew this was his chance. That first girl was just too picky. He often preferred the younger girls himself, but if he wanted to find someone that was interested in him, and then maybe later when he was a she, he had to open up his options just a little bit. With a smile, and a wag of his tail, he turned back to the bar. He had to think how he could attract her towards him. The moment she got close enough, Brian turned around, opened his mouth, and belched then and there. It was a loud deep belch, one that shook his very lips- and right in front of the woman's face no less.

Without even so much as exchanging names, the woman's mouth dropped. Not a moment later, that mouth raised back up and, with an angry glare at Brian, she slapped him with that free hand and commented "Creep" before she walked away.

Brian spun on the bar stool briefly- he didn't even realize the place had spinning barstools. By the time Brian stopped spinning; he shook his head and took a moment to recover. He then shot a glare of his own right back at the woman, who by now went to the back of the bar. "I didn't realize you were..." he paused before he finished that sentence. Hadn't he said that before? He turned back to the bar and scoffed. "Women are too fussy these days I swear. I belch and fart, totally normal and natural things for a dog to do." He reached down and patted that belly of his. "Whatever. I'll just become Lois and I'll have all of me to myself." He hopped off the bar and that gut wiggled with him when he jumped down. He hopped back up to grab the rest of his nachos, before he then went to the bar entrance. Once at the door, he glanced back briefly. His eyes weren't fixed on that woman he just saw, rather, his eyes turned briefly to a man- a rather fat man with his back turned to Brian, a man so fat, Brian could see the man's own ass crack with those small pants of his. There was something about that man that Brian couldn't place- something about him that just seemed so...attractive. He shook his head, and decided it was best to just go back home. He clearly wasn't going to get any action from women today, may as well just sit on the couch and eat until that transformation happened to him.

Brian didn't get too far out of the bar before his stomach rumbled. "Hrm. Those nachos and all of those hot dogs weren't enough." He hopped in his car and started it up. Sure, he had some drinks, but a couple beers were barely enough to make him drunk, plus it wouldn't be the first time he drove after drinking alcohol. "Ah I'll get some fast food on the way home. I'm hungrier than a hungry hippo."

The scene then switched to that of four hippos at a restaurant- a pink hippo, a green hippo, an orange hippo, and a yellow one. Each hippo looked largely identical aside from their colors. They had overly fat stomachs sticking out underneath the table, and eight fat, blubbery arms, arms that shook the table as they pounded in unison with forks and knives. "We want our food! We want our food!" they chanted. The table was about six by six feet, decent, but not that huge. A human waiter eventually set down a huge plate- a plate of giant oversized white balls stacked up in a pyramid, a good 20 in total, almost enough to cover the table. The hippos stared at those white balls before they suddenly reached forward and began to rapidly chomp and gulp them like wild animals. Their necks stretched awkwardly as they ate- those white balls. When all of the balls were gone, the green hippo jumped out of his chair and shouted "I ate the most! I win!"

The waiter casually set down the bill once the hippo jumped out of his seat. "So I take it you'll be paying most of this bill, then."

The green hippo took hold of that paper and raised it up to his eyes. Upon a quick glance, he fell down to the floor, and white balls flew back up.

After some time, Brian got back home. The door opened with ease, but Brian had quite a bit of trouble walking in. The first thing that got in was a belly that stuck a good foot out from his muzzle. Brian's fat almost dragged to his knees with his weight. As he waddled inside, that fat ass of his let out a fart. He turned around and closed the door behind him before he noticed Chris and Meg on the couch- both of them couldn't resist staring at him.

Meg opened her mouth to speak, but Brian held up a paw, a paw supported by a flabby arm. "Shut up, Meg." He walked his way behind the couch and over to the stairs. He glanced up at those stairs, gave a dismissive wave, and then went into the kitchen.

Chris and Meg exchanged stares before Chris turned back to the television. Oddly, the television wasn't the same one as before that Stewie broke. It was the same model as the broken one, but this one was actually in working order. "I don't know what's going on with him, all I know is I don't want to know."

Meg turned to Chris, and she gave him a cold stare. "What the hell Chris? There's definitely something wrong with Brian- how does someone get that fat so fast?"

Chris turned to Meg with a shrug. "How did you get so ugly so fast?"

Inside the kitchen, Brian was helping himself to a sandwich- a sandwich comprised of just about every kind of deli meat around- ham, roast beef, salami, corned beef, turkey, and bologna, to name a few. It was topped with a single slice of lettuce, and cheeses of a variety of different colors. The sandwich itself was almost bigger than Brian's mouth, and it stretched as long as the table. Brian took a seat on one of the chairs and pulled himself in- that gut of his kept him from pushing himself in that far, though. He opened his mouth, and took a large bite of that sandwich the moment Stewie walked into the kitchen.

The moment Stewie saw Brian and how fat he was, his eyes widened. "Good god Brian. What happened to you? You look almost as fat as the time Peter imagined what you would be like when you were neutered."

"How do you know what he thought?" Brian said with his mouth stuffed full of that sandwich. He didn't even so much as look at Stewie though, he just focused right on eating.

Meanwhile, on the other side of the kitchen door, the sound of punches could be heard as Chris and Meg rolled around the floor and knocked over a painting as they battled, although it was extremely faint, the noise could be heard in the kitchen. Neither Brian or Stewie seemed to react to the fighting.

Stewie shrugged. "I- I'm just trying to make a comparison for the audience." He spoke quietly, before his voice returned to normal. "Anyways, listen Brian, you should have started to develop some human traits by now- such as Lois's figure, but you're obviously too fat to be Lois, so something else must be going on. You'll have to come up to my room for an examination.

Brian scoffed at Stewie as he continued to eat that sandwich. "You worry too much. Lois definitely weighs more than me. Maybe I just need to weigh as much as her or something." True, not even he could explain the large amount of weight he put on. For a dog, he was downright obese, but something in the back of his head just told him not to worry about it.

Stewie grimaced for a moment before he spoke again. "Brian, do you know HOW I got Lois's DNA?"

Brian wasn't entirely sure. Stewie did explain his inventions on occasion, but even then, it was often difficult to understand how it worked. How DID time travel work exactly? How did multiverse travel work? "I don't know? Does it have to do with my weight?"

"Let's put it this way Brian, I needed a sample from Lois. I couldn't exactly get a saliva sample, and my safety scissors didn't cut through her hair, so I did the next best thing, I took a sample from between her legs. However, if the fat man did something between her legs, that could have tainted the sample I obtained."

"Wait..." Brian swallowed that part of the sandwich- it was already a third gone despite how much of the table it took moments ago. "You went between Lois's legs and got a sample there? Like a urine sample? And if they had sex, it could have been tainted?"

"I don't know what you mean with the whole 'sex' thing." Stewie replied, with a tilt of his head. "But yes, between Lois's legs. We don't have to get into technical details, just come upstairs with me."

Brian had to wonder. Of course he had a very good idea how Stewie got that sample. There were times when he was a young innocent child, and other times when he did such strange things that one would call downright perverted and disgusting, but Stewie didn't know any better- he was still a baby. "Alright. I would come with you, but I can't get up the stairs with this belly." Brian pushed out the chair and turned to Stewie.

Stewie rubbed his chin with his fingers and a light 'hrm' before he smiled. "I got an idea. Hop down onto the floor and get on your side."

Brian climbed out of that chair, not quite sure how he was able to so effortlessly get up onto it in the first place, and leaned onto his side. He was soon on his back with his fat on top, and below him. He wiggled his arms and legs, and looked at Stewie upside down. "I can't get back up! God, now I know what a turtle feels like."

"No time for a cutaway scene Brian." Stewie commented. Stewie walked to Brian's side and pushed him away from the chair. Amazingly, whether through cartoon physics or otherwise, Brian rolled on his side like some sort of beach ball. Stewie rolled him out of the kitchen and into the living room, where the fight with Chris and Meg continued.

The living room was a mess. The couch was tipped over, the television was broken again. Chris and Meg continued to exchange punches and blows with scratches, blood, and various bruises on their body.

Stewie paused only briefly when he rolled Brian, just for Chris and Meg to get out of the way with their fighting- Chris had just pushed Meg right up against the wall, but Meg grabbed a lamp and smashed it over Chris's head before they moved out of the way, seemingly unaware that Brian or Stewie were even there. Stewie then continued to roll Brian casually over to the stairs. Step by step, Stewie pushed him up. It was definitely a struggle, even moreso when Brian farted right in Stewie's face about halfway up. Stewie held his breath and continued to push, now with his back turned towards Brian.

After what felt like hours to Stewie, he managed to get Brian into his room. Stewie examined Brian with a 'doctors kit' designed for children- large oversized pink plastic toys that didn't work very well on people. Stewie stuck a large pink fake thermometer in Brian's mouth for only a second before he took it out and glanced at the sticker on the other end. "One hundred and one, definitely a fever."

Brian rolled his eyes. He sat on a large red baby chair with his feet just inches above the ground. How Stewie got him upright into that chair was anyone's guess. "This is supposed to be about finding out if what you gave me was tainted or not."

"Right, right..." Stewie walked away to his crib for a moment before he pulled out what looked like a small touch computer screen. He walked back to Brian and held the screen over his gut before he turned it on. "Let's see..." The screen displayed a circle cut into three parts, and names in all of the circles. Brian, Lois, and Peter. "It's just as I feared. Somehow, the fat man must have got a liquid between Lois's legs and tainted the serum. You're currently roughly 70% you, 20% Peter, and 10% Lois."

Brian raised a brow at that. Stewie had such the oddest inventions, how did that touch screen even work? Regardless, there was another concern. "So, the 70% is me still being a dog, the 20% Peter could be..." he paused to think for a moment before he farted once more then and there- a loud 'pfffrrtt' coming from that ass of his. The sheer fact nobody seemed to pay attention to the smell could have been purely because Peter had done it so much already that the house already smelled faintly of farts anyways. "Maybe me doing that is..." he said quietly. "But...what part of me is Lois then?"

There was a sound of a car crashing outside before the front door opened. "Lois, I'm home! And...and before you ask, I'm not drunk, I'm uh...not...not...drunk." And then he hit the ground with a thud.

"I'll be down in a minute, Peter!" Brian found himself shouting in a voice just slightly more nasal than what he normally said. Brian then covered his mouth with his paws, and his eyes widened. A mental part of him- that must have been becoming Lois. Even the thought of Peter naked flashed in his mind, and that actually excited him. He had seen Peter naked plenty of times before and didn't care, but knowing the mere thought now made him aroused? That disturbed Brian more than the fat he gained. "Stewie, what the hell is happening?"

Stewie put away that touch screen of his before he looked out of his room briefly and then back at Brian. "I don't know. You were designed to become Lois physically, not mentally- DNA should not have effected the mind, but if you're just responding to Lois's name, then I'm sure it's nothing that much to worry about."

Brian grimaced for a moment. "It's more than that. I actually...I think...I think I'm starting to like men more than women." It only took him until now to realize he hadn't thought about women since he arrived home. It was all about men now, big fat men, maybe a bit stupid on the side.

"So?" Stewie asked with a casual shrug.

"Oh, right." Brian's eyes lowered. He looked away from Stewie and rolled his eyes. He still had no idea how innocent Stewie was- sometimes he didn't know better; other times he KNEW that...well...he wasn't going to bring up Stewie's sexuality. "How about this? I'm starting to like big fat men like Peter more than women like Lois."

"Oh." Stewie's eyes lowered as well as he expressed disinterest. "Excuse me a second." He walked out of his bedroom, and Brian could pick up the sounds of Stewie vomiting before Stewie came back, and slapped Brian. "What the hell, man!? Alright, alright, alright, look, I need a DNA sample from you so I can try to isolate your gene and turn you back to normal."

"So you need my blood drawn or something?" Brian asked. He already knew how Stewie got Lois's DNA, but how would that work for men? Unless...

"No, I need a sample from...between your legs specifically." Stewie gave him a small cup. "Just uh...just fill that up and bring it back."

Brian took that cup, and glanced at Stewie. "So do I fill it with urine then? Or..."

"Urine isn't ideal for a DNA sample. You can make that white stuff come out of there though. That's the kind of sample I would need."

"Wait, so how do you know about sperm if you don't know about sex?" Brian had to ask. Stewie was just so confusing at times to him; he needed some sort of clarification.

"It's a long story involving testicular boot camp, shooting down pilots, and the man in white. Now, just go in the bathroom and get me a sample before the fat man sees you."

"Fine." Brian said with a huff. He waddled out of Stewie's room, and made his way towards the bathroom.

"And no licking up the puke on the way!" Stewie shouted moments after Brian left the room.

"Oh come on!" Brian shouted from the hallway. With a huff, he went straight to the bathroom.

It was amazing neither Chris, Meg, or even Peter didn't hear any of their conversation, but then again, Peter was passed out, and Chris and Meg were doing...well it didn't seem to matter, they didn't pay attention.

Brian closed the door when he was in the bathroom and sighed heavily. He held up that cup- that tiny plastic cup smaller than his own paw. "So, I just have to get myself aroused enough and give him a sperm sample." Brian tried not to think how weird the idea was; instead he just tried to think of Lois naked. It wasn't a tremendously hard think for him to do, he had actually seen her naked many times before, but he wasn't the type to straight out make a move on her, at least most of the time. He laid down on the white tiled bathroom floor and continued to think about Lois, all while leaning down and trying to lick himself, but with all of that fat in the way, he just couldn't get down there. "Great." He muttered. He would have tried to think of a comparison to this, but he had to keep focusing on Lois. Still, no matter how hard he tried to think about her, and no matter how hard he tried to reach down between his legs, he couldn't reach his own cock, nor could he even get aroused from thinking about Lois.

As Brian kept trying to think about Lois, he felt that big stomach rumble. He wasn't concerned at this point what it was- and he just let out a belch then and there, a loud one that shook the whole bathroom. Brian swore that he heard the sound of Peter laughing, and then he felt something twitch between his legs. "Oh god..." Brian muttered. He wasn't turned on by Lois, but the sheer thought of Peter definitely worked. He loathed the idea about thinking of Peter to arouse him, but Stewie needed that sample from him. He closed his eyes, and thought of Peter naked. That big huge tub of lard body, farting, belching, it was absolutely disgusting on one end, and yet the other part of him knew it was working, he could feel himself turned on between his legs, even if he couldn't quite reach it. "I just...how am I supposed to..." he was too fat to reach down, with his paws, or his head.

Brian continued to think of Peter, and added himself in the picture. He let that mind of his wander, and it wandered to, not Brian having fun with Peter, but Peter having fun with Brian. It was actually difficult to picture- the two were flat out obese. He imagined Peter moving his fat up and laying down, while Brian had his back turned and ass exposed to him and sitting on top. It was easy to imagine what Peter looked like naked- he had seen it so many times before, but never had Brian been aroused by it until today. "God..." he muttered, half in disgust, and half in arousal. He could feel himself aroused and erect between his legs. "At least I found my penis." Still, despite him getting so aroused, he just couldn't get that sample. He just needed something- a little push to get him over the top.

About then and there, there was a knock at the bathroom door. "Whoever's in there, I got to take a crap." It was a slurred speech, but it was definitely Peter's. It was around then that there was a loud fart from him on the other side of the door. "Whoops! Nevermind. Now I just need a change of pants."

Brian moaned quietly. He felt that cock of his twitch, and then cum then and there. It was one thing for him to fart and belch, but for Peter to do it, the same one he just fantasized about, that proved too much for that doggy cock of his, the one he couldn't even see. As Brian orgasm, and felt that soft seed on the lower part of his gut, he felt something else between his legs, something that was shrinking, moreso the more he came. He felt other things about his body change, changes he couldn't quite focus on due to the pleasure of his orgasm. His nose shrank down a few inches and pointed out just a bit- the same nose pinkened slightly, and some of the fur on his body shed down on the floor. Underneath the fur revealed humanish skin. Brian also grew a couple of inches in height, and after that, he finally stopped that orgasm, and the changes went back to their slow progress, rather than the rapid changes they had just gone through.

"God...that was more intense than...than..." Brian wanted to think of a comparison, but it just felt so hard. He didn't feel anything between his legs now- was he a woman? He couldn't even check. At the very least, he had that semen sample. Brian slowly stood up, the new few inches in height helped balance him out a bit. He leaned down, scooped up the sample, with some dog hairs, and left the bathroom. Thankfully, Peter had left- and he left a dirty pair of pants behind. "Great. Hopefully he put on a new pair of paints." Brian muttered. Then again, part of him hoped Peter didn't get on a new pair.

Brian returned to Stewie's bedroom and shed quite a bit of fur along the way. By the time he actually made it in that bedroom, his nose looked far more triangular and shorter, he was about half a foot taller, and those ears shifted a bit lower on his head. At least he didn't gain any more weight- it was as if all of the weight he had meant to gain happened first, and getting taller helped distribute that weight a bit better rather than just largely in his gut. "I got the sample." Brian said- he held out a cup that had not only a lot of white fur, but was also quite sticky.

"Good lord." Stewie commented after seeing Brian's so significant change. "Your nose- your fur- you're shedding worse than a tree that sheds its leaves during fall."

The scene briefly switched to that of two trees standing side by side- both of which had plenty of leaves on their branches. One of the trees developed a mouth in roughly the center of its body, and it spoke. "So Ted, I heard stress can cause your hair to fall out early." The voice spoke in a high pitched womanly voice.

"What does that have to do with anything?" the tree replied in a manly voice, and also with a bit of confusion.

"Well, I'm pregnant." The first tree replied.

"Oh. That's nice." The second tree stated in a rather monotone response. Rather suddenly, each and every leaf on the first tree, not only turned brown, but fell off of that tree in one big giant clump.

The first tree couldn't help but laugh a bit. "Oh Ted, you're so funny. We're TREES. We can't get pregnant. Did it really stress you out THAT much?"

After a moment of silence from Ted, he replied. "Good point. So I guess that other tree I slept with won't get pregnant, then."

The first tree's leaves turned brown then and there, and fell off in a big huge clump. "Wait, WHAT?!"

"Sorry, I just thought I would branch out a bit." Ted replied, and after a moment of silence, just laughed. "I can't believe you fell for that! We're rooted to the ground, we can't move at all!"

Both of the trees laughed together before they froze in place. Words appeared in front of them and voices came from a chant of people, as if they were advertising for whoever was watching. "Trees! They can't have sex!"

Back in Stewie's bedroom, Brian let out a frustrated sigh. "If I'm becoming human, it's only normal to lose most of my fur. That's not what I'm worried about- I'm more worried about what I had to do to get this sample. I had to-"

"Brian. Brian." Stewie cut Brian off. "I don't want to know." He put on a pair of gloves and took the cup. He walked over to a large black box machine where he put the cup inside a small square opening. The opening closed, and a screen on the box lit up. "Alright. This is going to take some time. Until then, if you must shed your fur, we may as well speed up the process and help prevent you making a big giant mess from shedding." Stewie laid down a large sheet of plastic- about five by five feet. "Just stand on there and we'll get rid of the rest of the fur."

"What are you going to do? Shave me?" Brian stood on that plastic sheet anyways. He didn't even bother asking where Stewie got the things he got anymore these days- those machines, that plastic sheet, how could he afford it? Well, then again how could Peter afford blimps, helicopters, and various other things he obtained?

"Don't be silly, Brian. I can't even use safety scissors. No, we should just be able to use a comb." Stewie put a comb to Brian's gut, and moved it upwards. It wasn't a particularly hard comb; it actually had quite a lot of soft bristles. As that comb moved along Brian's gut, Brian's hair fell off of his body like soft snow. The more Stewie combed off, the more pinkish human skin was revealed underneath that white fur. "So, how's your day been?" he asked casually, as if to create conversation.

Brian rolled his eyes at the question. He merely watched as Stewie continued. As Stewie got to Brian's paws, Brian looked at his front paws and noticed his paws could stretch out a bit more than before- they were still short and stubby, but they weren't as restrained. Then again, it was often hard to tell that they were restrained with him. It wasn't too long before Brian was completely furless. He looked back and noticed that tail of his wasn't even there anymore- just a giant ass. The front of him he still had a long nose- but it was pointed at the end and humanish, just like the rest of that nose. The only part Brian still had any fur on was at the top of his head- that just didn't come off, but it looked more pinkish than white. "Reminds me of the time all our hair shed at that lake."

"And you still have that Ziggy tattoo." Stewie added with a laugh. That comb of his stroked between Brian's legs before he tossed it away. "Anyways, that takes care of the fur, and that serum should be ready any moment now too."

"Well, I wouldn't mind to keep changing into Lois, just so long as all of this Peter in me gets out." Brian commented with a shrug. "I mean, the whole point of this was for me to become Lois, wasn't it? So long as I'm not so fat and gassy." He coughed. "Then it should be fine." The voice he spoke after Brian coughed sounded a bit higher pitched than before.

Stewie sighed heavily. "The serum should make something that isolates the Brian in you, the Peter in you, and the Lois in you. I'm still concerned about how you responded like Lois though- the last thing we need in this house is for there to be two of her."

The device Stewie put the serum in let out a light ding. The opening Stewie put Brian's cup into slid back open and revealed three syringes- a red one, a white one, and a blue one. The syringes were ones without needles- one simply had to drink it, not inject it. Stewie glanced over at the three of them, and then he looked back at Brian. "The red one should be Lois, the white one should be you, and the blue one should be Peter. If you really want to continue to become Lois, I can't stop you, but just be warned that if you think like Lois, I might not be able to reverse your mind."

Brian glanced over at the three vials, and then back down at Stewie. He walked over in front of that opening and looked at the three possibilities. "What about the...uh..." he paused and farted once more, a loud pfrt escaped from that ass of his. "Uhn...that?"

"Ideally it SHOULD go away when you take either Lois, or your vial." Stewie explained. "Either that, or at least lessen to a large degree."

Brian didn't like the sound of that- Stewie sounded unsure himself. "Well..." he took the red vial, and downed it with little a second thought. The idea was to become Lois, not to fix the situation he was in. So long as he stopped being so fat and he stopped being so gassy, he could live with Lois's mentality. Maybe Stewie could fix him up after. "Just remember, that Ziggy tattoo should stick with me once my change is done, and that'll be the difference between Lois and me."

"Well, hopefully the 'you' in there won't be erased." Stewie was at least that hopeful. "I'll work on developing a way to fix you, but in the meantime, you might want to put clothes on. It's bad enough we have the fat man running around naked half the time, we don't need a Lois doing that too."

Brian nodded, and walked out of Stewie's bedroom. He made his way to the master bedroom, and glanced down at the floor. The fur he had shed along the way was all gone. The only thing left on the floor upstairs were those dirty pants of Peter's. Brian went into the bedroom and opened up the closet. With a light 'huh' from him, he noticed the clothes in there were essentially the same- Peter had a white top and green pants, a good ten plus pairs of them, while Lois had a light green top and khaki pants, again ten pairs of them, all lined up neatly in the closet. "Well, that explains why it looks like they never change clothes." He said quietly.

Before Brian could put any clothes on, he let out a belch- a belch that sounded frighteningly a lot like Lois would have made. It wasn't so loud that the whole house could have heard it, but it felt like a powerful release of gas- so strong he had a sense of vertigo afterwards. Brian shook his head, and blinked a few times- he grew another few inches, and then another- he rapidly gained inches until he was a good foot taller in height. In comparison, he was about halfway between what his height was, and what Lois stood at. "Weird..." even Brian's voice sounded so much more like Lois's- higher pitched with a nasal hint in it. Giving in to his vices seemed to accelerate the change- but one thing was certain, he wasn't losing any fat or any slob part of him- he'd have to hope Stewie could reverse that eventually.

Brian took Lois's shirt and put it on over him. Surprisingly, it fit well- all of those shirts were the same size for her thin self, yet this worked amazingly somehow. "Huh. Not going to complain." Brian closed the closet door and saw that red hair on top of his head- it looked like it was growing down rather quickly- already halfway down the back of his head. His nose had been pushed in even more, and his sex? Well, in a mirror he could see underneath his belly, but the shirt was a little too long for him to see it. How the shirt even fit him as incredibly well as it did was anyone's guess.

"Lois? Is that you?" Peter walked into the bedroom, turned, and stared down at Brian. It was amazing how he was able to get so sober so quickly. It seemed like just moments ago he was walking around like a drunk. Worse yet, he didn't have pants on. Sure it was hard to see Peter between his legs, but his lack of pants was still obvious. "Lois? You're home early, and you're short. The heck happened to you?"

Brian froze in place when Peter spoke to him. He looked so much like Lois, that even Peter called him that- or maybe he was just that stupid...which that was probably the case. Brian wasn't sure how he should even respond. A fat man like Peter, a fat man who lacked pants, a fat slob man, he was such a turn on for Brian now, and here the two were, alone in the bedroom. "I uh..." he tried to think about what Lois might say. Amazingly, what Lois might say came up in his mind far sooner than he thought it would have. "I managed to fix mom and dads relationship pretty quickly." He replied as he turned to Peter. "I just got home not that long ago."

"Huh. You must have gone through the window to get in. Good thing too- Meg and Chris are passed out on the couch after a bunch of fighting." Peter blinked for a moment before he changed the conversation. "Why don't you have any pants on?"

Brian already knew about the fight. It worried him a bit more for some reason now, more than it normally did, as if those two were his kids- but he knew better, Chris and Meg weren't his kids...weren't they? "I could ask you the same question, Peter." Brian replied with a stern voice.

"It's a long story involving drunk, molting, and crapping, in that order." Peter said with a shrug. "Anyway. I dunno what's happened to you, but I like it. Come here." Peter leaned down and gave Brian a hug- a big fat hug where their bellies rubbed each other. "Even if you're shorter for some reason."

Brian thanked his luck that Peter was so stupid. His mind told him to pull away from Peter, but he found himself unable to. He felt that huge belly of Peter's rub against his, with only their shirts in the way, Peter's hairy legs inches away from Brian's hairless ones, and Brian's face inches away from Peter's chest. Brian belched quietly, and after a brief sense of vertigo- he was now looking at Peter's chin- not quite as tall as Lois, but much closer. "I should really...I should go check on the kids." Brian had to try to think of something, anything, although he found it hard to come up with a reason to escape Peter's grasp. That Lois in him wanted to just take him to town after...god how long had it been? He had never been laid by Peter! That needed to be fixed. Brian shook his head a moment later to get that thought out of his mind.

"I don't know where you got that belch from, but I love it. Also, don't worry about the kids, they're old enough to take care of themselves, all two of them" Peter replied back with a seductive voice. Well, as seductive as Peter could make his voice. He slowly inched Brian closer and closer to the bed. He couldn't help himself but kiss his neck, his cheek, and he leaned in for a kiss right on the lips.

Brian was amazed that Peter moved him around so easily. Already, Brian was inches away from the bed, and Peter wanted to kiss him right on the lips. Part of Brian wanted to resist so much, but that mind of his, that mind that had conflicting arguments left and right, it told him to accept it- this is what he wanted, this is what he could enjoy. Who cared about young women? This was a fat disgusting man, and it was Brian's type. Brian's fingertips, fingertips he felt that functioned far more like hands than actual paws, gently moved around Peter's back. His toes curled, and he gave in. Brian kissed Peter square on the lips. As Brian kissed, he felt an incredible rush of arousal between his legs- but it wasn't an erection, it was wet. Brian couldn't see his sex between his legs, but he just had a feeling that calling himself a 'he' wasn't the proper way to refer to himself anymore. He had become a she, a she that resembled more and more like Lois- although she still had quite a bit of weight in her gut, and on her arms, her legs, and her tits. She glanced down during the kiss and saw that those moobs of hers had fleshed out into fully formed tits, a single pair no less. Brian broke that kiss, and panted lightly. "I...I need a moment Peter, for girl things." She managed to say. She had to say something, ANYTHING to break the moment.

"Oh, I get it." Peter said with a sly tone, and a light giggling laugh. "You need a minute to prepare. I'll be on the bed when you're ready." Peter gently released Brian and walked over to the bed. As he displayed that ass of his, he ripped a fart then and there- less than a foot away from Brian. "Sorry." He added in a coy tone, right before he got onto the bed on his side, showing off his naked body entirely to Brian- including that cock that was visible when Peter was on his side. It was about average in length, and it was easy to tell he was aroused.

Brian hesitated for a moment once Peter farted. She was pretty sure Lois despised that sort of grossness, so...why did Brian absolutely love it? The dog part of her found it tolerable, the Lois part hated it, but Peter perhaps...it was clear the Peter in her wasn't entirely gone. Brian cleared her head long enough to run to the bathroom. Once there, she took a look at herself in the mirror to see just how much she had changed.

Brian was almost at Lois's height- maybe about a foot to half a foot shorter, but definitely no longer her original height. The hair on top of her looked exactly like Lois's- it was reddish orange, and it circled around the back of her head. Her nose was triangular and looked exactly like Lois. In fact, a lot of her looked so much like Lois, with the exception of her fat. Even those tits of hers in her shirt were expanding to be larger than Lois's with fat, large enough to rest on that fat gut of hers. Her arms were chubby; her legs looked like two giant tree trunks, and while she couldn't quite see her ass, she could feel the fat wiggle behind it. The only bit of Brian left in that body, was her mind, but even that had difficulty staying around. She stared at herself in the mirror with those tiny eyes, and then she looked down at her hands. "I really did become Lois- a big fat version of Lois, but I'm Lois."

Brian glanced at the bathroom door, and she recalled Peter- Peter who waited for her to return, Peter who was ready for some fun, and with how turned on Brian was now, so was she. "I shouldn't though...I'm still Brian..." even her voice sounded like Lois. Brian closed her eyes and grunted briefly before she farted again. When she reopened her eyes, she was at Lois's height, just like that. Brian wanted to make a comparison, a cutaway to something, but all she could think about was Peter's naked body, and how she wanted to throw herself to him. There was only one more hope for Brian, one more thing that she could do to resist. Brian didn't care she lacked pants. She opened that bathroom door, and went straight into Stewie's bedroom. "Stewie- you got to help me, I'm thinking more and more like her!"

Stewie turned to Brian, and his eyes widened. He couldn't believe what he was seeing- a Lois that lacked pants. Of course he was still a baby technically, plus he had mentioned he had to get a sample there before, but he knew this wasn't Lois- this couldn't have been. Stewie opened his mouth and spoke, but each word he spoke, Brian didn't understand a word of it.

There was a sudden cutaway of two hippos- one sat in a lake as if it were a pool, the other stood nearby it. Aside from one of the hippos that wore a pink bow on their head to signify they were a girl, that one being near the lake, they looked nearly identical. "So," The hippo in the lake said in a deep bass voice that almost sounded like Steve Barry. "Want to turn this lake into a hot tub?"

The other hippo grinned down at him. "Oh that would be hipp-out of this world!" she said gleefully, and quickly dived in right next to him. Together, the two farted happily and created multiple bubbles behind them- and quite a bit of steam all around them.

Back in Stewie's bedroom, Brian commented. "I'm sure that would have been much more humorous if I knew what you were saying, Stewie." Her tone and her voice sounded very much like Lois, and she rather suddenly showed disinterest in Stewie. "It's getting late now, time for bed." Brian picked up Stewie and put him in his crib. She then turned and walked back to the hallway, and flashed that bare butt of hers. She swore there was something she wanted to tell Stewie, but that weird cutaway distracted her- what was she doing again? She glanced down at her bare legs, and then over at the bedroom. That's right- she was going to have fun with Peter.

Brian still knew deep down, she was a he, but...she wasn't very concerned about it anymore. She was now Lois physically, aside from that fat and her gas, and she thought much like her mentally. Sure she was fatter; sure she had a ziggy tattoo on her bare bottom, but that didn't matter. Brian walked back to the bedroom, paused at the entrance to let out a womanly belch, before she closed the door behind her.

Inside the bedroom, one could pick up the sounds of the bed rocking, Peter grunting, farts and belches from the pair being mixed, and then Peter finally shouting "Shazam!"

A moment later, Brian cooed quietly. "Aw, good for you."

Things might get odd when the real Lois returned, but for now- nobody really complained about this fat Lois in the house, definitely not Peter, and not Brian.
