You hang out at home for a day

You lay on your stomach for a few hours and enjoy the sunlight heating your ass cheeks as you sweat like a beast. It was quite a hot day but despite your enormity and your body burning, the heat felt really good as did the constant sweat building up on you. It was eventually disturbed by water from a hose pelting your ass. Your protests are drowned out by your father turning the water on higher to clean your fat up with a high-powered hose. You submit and work with him to get between your folds before you roll over onto your gigantic ass and hold up your pits. You grab your moobs and lift them up for him to clean beneath them and you lean left and right so he could get some of your side fat rolls.

"There," he says proudly as you sit there in all 8000 pounds of your fat glory dripping with water. You're exhausted from moving so much as you watch your dad gather up the hose.

"Did I really need a bath?" you ask panting for air.

"If you're going to continue wearing nothing but that thin jockstrap, yes. And you especially should be clean when your boyfriend's cum is drooling out of your ass." He finally puts the hose back in its outdoor chest as he turns to look at your enormity.

"Hmm," you moan as you just picture Harry's massive meat gliding into your ass again. "I want to go have sex with him again right now."

"I'm sure you do," your dad says as he grabs towels and starts throwing them onto you. "But when he's not around your only choice is your brother."

"What? Really Dad?" you're shocked he even made the suggestion as he starts drying you off. Your massive body wobbles incredibly as he shakes you and you love the feeling. You grab a towel and start playing with your moobs to help him.

"Look, you're both insatiable and I couldn't stop you even if I wanted to. I know what those infections have done to you boys. You're hungry and horny all the time, and he's even hornier than you are all the time. You're gonna cross boundaries every day now, hell you already love walking around naked like you own everywhere you go. I'm just saying, you want sex with a dick as big as a car? Your brother has one. I'm sure he would appreciate being able to fuck something other than a tube."

You take in what he said and just sit on it as you help your father dry you off. By the time you're done, your mom comes out to let you know your breakfast is ready. You haul yourself onto your feet and march inside. It's a tight squeeze through the double doors and pretty much everywhere in your house, but you manage and your parents took everything off the walls and out of the hallways so you had as much room as possible and not destroy anything. You finally reach the kitchen and your flab is no longer constrained by the walls of the hallways and buoys out like a cartoon to return to its normal shape.

You sit at the small table as your mom delivers to you a feast for a man of your size. The food just keeps coming and coming and coming as you eat and eat. Your recently cleaned chest becomes lost under a tarp of sauce, food debris, and grease. You orgasm. You orgasmed over and over again too. Like your father said, that virus did something to you. It didn't just make you impossibly fat, it made you hungry. Not just for food, but sex. Food is so good to you now that just eating it can get you to orgasm. And your ass, now that you've had sex, it's screaming to be filled. The more you eat the hornier you get, and the more you orgasm. Your hunger for food and sex is so strong you eat through lunch too just to cum some more.

"That's all I can make for you right now, IYNH," your mom says delivering you one last plate of food. You eat it within seconds and get so close to another orgasm, but it doesn't come. "I need to start preparing for dinner, so you'll have to settle for all of that for now."

"That was just enough, Mom," you say slowly hauling yourself up. "I'll see you for dinner." You stomp out of the kitchen and your dad has a bit of a chuckle seeing how much food is all over you. You decide to head to your room in the garage and so you head back toward the back door as it's the only door you can get out of the house through. You reach the hallway that leads to your old room and your brother's room however and pause. You can feel your dick throbbing in your fat pad. It's so close to another orgasm. You want it. You want to be fucked.

You turn down the hall and reach your brother's room knocking on the door. You can hear whatever machine is inside chugging away at your brother's dick and it appears he can't hear you over it as you knock again and get no response. His howls further drown you out as you call out his name. You decide to open the door and within a second your fat floods into it plugging it up.

"IYNH?" you hear his muffled cries. You push through slowly easing your fat in little by little through the double doors. You finally pop in and your fat falls inside nearly taking you down with it. You correct yourself as you finish getting your ass inside and marvel at the machine pumping your brother's dick. It's quite a large piston system chugging along to keep the flesh toys inside the pump moving up and down his cock as it throbs in orgasm. The constantly refilling white hot cum gets sucked away somewhere else as your brother sits at his computer desk and is caked in sweat as he moans in another orgasm. The balls that stand taller than him visibly constrict and relax rhythmically as his 10-foot cock that he's straddling like a horse grows taut and throbs pumping more cum out of it.

"What are you doing in here?" Your brother asks as he moans to another orgasm. His legs barely reach the floor as he sits on his cock and you take a moment to admire his physique. Obviously not as big as you he's still much bigger than normal men. His chest is stacked with beef and his belly is hiding an obvious layer of abs that are bigger than any normal guy's. His arms and legs radiate strength beneath the layer of fat as well and it's obvious he weighs over 1000 pounds. You can't believe you're thinking about how sexy your brother is but you can't stop it now. Your dad implanted this idea in your head, and you want to do it now more than ever.

"I want you to fuck me," You demand. Your brother recoils a bit in shock as he shakes his head as if shaking it will help him un-hear what you just asked.

"You want me to what?" The shock and confusion are thick and you question asking him for a moment, but you stand firm in what you want.

"You heard me," you say taking a stomp forward. "Dad said it right, we're different now. That virus made us both so horny, and I can't think of doing anything else right now. I want a mammoth of a cock to get in my ass and use me like a toy and Harry isn't here."

"Dude, we're brothers, you really want me to fuck you?"

"That's what makes it even sexier. I never thought I'd look at you and think about how much I want that cock inside me, but right now, it's all I can think about. Your beefy pecs pushing against my ass, those muscular arms separating my ass cheeks, and that cock throbbing inside of me as you pump me full of your seed. I want it all. I'm sure you've had some thoughts about me too. Look at how fat I've become," you tease him as you throw up your arms to show your pits. Your fat arms sag downward barely letting your pits even free to show. You watch him avert his eyes, but he can only do so for a moment before eye-fucking you up and down. "I'm an elephant of a man. I'm so fat. Fat enough to take a 20-foot cock let alone your 10. So are we doing this? Or do you want to keep fucking a plastic tube?"

Your brother takes a second before pushing his desk aside and getting on his feet.

"Let's fuck," he moans as he pushes a button on his phone. You hear a loud hiss as you watch the tube release the pressure holding itself on his cock and he glides his manhood free. The ten-foot cock swings and he aims it right at you. You stomp in place to turn around and show him your ass. You hear him huff to ready himself as you begin to feel his cock make contact.

"Oh, shit," he moans loudly as he stops pushing.

"What?"

"I- You know, you'll be the first person I've actually fucked with this thing," he says. "I've only ever gotten sucked off by that stupid tube."

"Well, now you'll have me, we can fuck whenever we want, and however much we want. Now put it in, and use me like a fat blob whose only purpose is being fucked."

Your brother huffs and readies himself as he finally pushes his cock inside you. You both moan loudly as he continues to glide it in foot by foot. You can tell it's a lot for him and it's showing that it's his first time. He blows his load several times before finally getting it all in. You feel him push up against your ass and grab handfuls of it with his meaty hands. He quickly becomes enthralled by your fat as he keeps grabbing at your ass cheeks and squeezing it and rubbing it. Your fat quakes as he thrusts in and out. Even though his 10-foot cock only moved a foot each time, it was 10 feet ribbing you from inside. You cum over and over again and your entire body burns in pleasure. Your brother grabs handfuls of your ass again and starts pistoning you. He thrusts over and over and over so fast as if trying to empty his balls of everything they have and tire himself out as quickly as he could. Your moans grow louder and probably reach the neighbors as your brother fills you with so much seed. He just keeps thrusting. Over and over, it's almost like he can't get tired when he's having sex. Your legs have long since given out and you've fallen on your ass just sitting there being his personal fuck toy. You grab at your belly and enjoy the quaking of your entire body with every thrust and feeling your belly fill with cum.

The hours rolled by and for much of it, your brother seemed insatiable and impossible to stop. His thrusting didn't let up for even a moment. His only pauses were to grope your fat and grab more of it. You loved every second of it, but even you had limits. As exhaustion and sleep took over, you passed out to the rhythmic fucking of your brother.

You woke up to someone pulling on you and you snorted awake lost as to where you were or what time it was when you looked down your side to see your father.

"Breakfast is ready," he tells you as he starts to walk away. You can still feel your brother's cock in your ass.

"What about him?" you say. You can feel his cock throb and start pumping you full of more cum.

"I-I-I'm almost, done," your brother moans from behind you. "Oh god, IYNH, thank you. This felt so good."

"It felt amazing, bro," you moan feeling his cum fill you up. "We're definitely gonna fuck more often now."
