The girls next door need to be taught some manners

"YES DEC, DICK MY ASS! YOU FEEL SO GOOD STRETCHING OUT MY BUTT! FUCK, I'M CUMMING AGAIN!!"

Declan grunted with effort as Vikki's sphincter clamped down around his thrusting length, the youngest of the family cumming violently for the second time in the last few minutes. Her sharply arched back pushed her giant breasts out, jiggling as she twitched, and the beautiful globes were enough to push Declan into his own climax, stuffing Vikki's ass with cum. He pulled out as soon as he was done, the rough removal of his dick making Vikki's ass convulse as he laid her down on the couch next to him. He had just a second to appreciate the sight of his seed leaking from her hole before Cora swooped in and started to lick it up.

"That's still so gross," Adeline said, from the other couch where she was masturbating and watching.

"What? It's not like it's good for anything else at this point. We don't produce anything. We don't even need to eat anything," Cora said between licks, her prodding tongue making her youngest sister moan into the cushions. She was right: once they were infected with the Contagion, they hadn't needed to eat or go to the bathroom at all. They could still eat and drink food, but it just seemed to disappear into them, never to be seen again.

"Besides," Sonja said, reaching over from next to Adeline, grabbing her face, and forcing her to look at their brother's still erect and cum-slicked shaft, "you know you want to go suck the cum off of that, no matter where it's been." Adeline's hips immediately thrust up toward her hand, her fickle submissiveness taking hold as her sister **** her to look.

"Yes...." she whimpered, longing for Declan's dick and jealous as Vikki recovered enough to take him in her mouth to the base. Of the four sisters, she was the one who loved blowing him the most, though none of them would turn away from a tasty load. Adeline took it to the **** though, sometimes just letting the pillar of manliness rest in or on her mouth for the sake of it. Either way, with Declan's cock momentarily out of sight, the submissive switch batted Sonja's hand away, happily going back to playing with her folds. "But I don't want to hear about obsession from you, Creampie Queen. You've got to leave some cum for the rest of us."

"No, what I need is to bathe my womb in seed until I get knocked up. And since that hasn't happened yet, I'm going to continue wringing Declan dry as often as I can." Sonja had taken her brother's heated words to heart when they first fucked and was dedicated to getting as many loads of semen in her belly as she could. She didn't know if she was pregnant yet, but she knew she wanted to be, so she had no intention to stop.

"You could always fuck someone else," Cora offered, having finished cleaning out Vikki's ass.

"Yeah, but my little brother fucking his baby into me sounds like so much more fun," Sonja said with a smile.

"Oh shit, you're right..." the slightly younger woman groaned with a shudder. She was definitely still the slut of the family, up for anything and everything, all the time. She had been practically a nymphomaniac before everything had happened, and now, a few days after they had all been infected, she definitely was one. Declan needed at least two hands to count how many times she had ambushed him randomly, horny and DTF, and even that probably wasn't enough. Not that he minded. Who wouldn't want to be balls deep in any one of his sisters, much less all four?

"Speaking of mothering, I saw Mom yesterday," Sonja mentioned, turning her attention to the TV where two women were competing to see who could swallow a pint of cum faster. Numerous failed attempts had necessitated several men to help refill the glasses. They didn't mind. "I'm pretty sure she's a total exhibitionist at this point. Either that or she really likes sexy dancing in front of people's windows."

"Speaking of anything more interesting than that," Adeline interrupted, "you guys know Hannah and Lei two houses over? They've been talking mad shit about all the men they have dying at their feet."

"Glad to see some things stay the same no matter what. Like those two somehow being enormous twats and total whores at the same time," Vikki grumbled as best she could with her mouth half full of dick.

"Yeah, I think they're even more insufferable after getting infected. You should see the shit they post. Makes me look like a saint."

"Saints don't masturbate to their sisters sucking off their brother," Sonja said, still watching TV.

"By comparison, Sonja, geez." Adeline rolled her eyes.

"So why mention it? Odd topic to bring up out of the blue," Declan asked, running his hand through Vikki's blonde hair and enjoying the weight of her breasts on his legs.

"Oh, because they're probably coming over here. Going to, and I quote, 'make that cute neighbor boy our bitch'. With a lot of emojis." Adeline's words were nearly prophetic, since a few seconds later, the doorbell rang. Then someone knocked. Then the doorbell rang again, and again, and more knocking. Already grumbling Adeline got up and sauntered over to the door, jerking it open and staring at the people outside with a flat stare. "Can I help you cunts?"

"Move it, bimbo, and I hope you took so long because you were getting one last fuck in. Once we're done with your brother, there's no way he's going to get hard for your fat ass," said a snooty voice from outside. Declan couldn't see its owner from the couch and wasn't about to interrupt Vikki's blowjob to see.

"In case you didn't notice, slut, you've got a lot more blonde hair than me. Color me not surprised," Adeline retorted.

"Suck a limp dick, bitch, and get out of my way." The same voice as before sneered as Declan's older younger sister got pushed aside and two women walked in with the most exaggeratedly 'sexy' walk he had ever seen. It looked more like they were having trouble keeping their balance with how much they were swaying. "Get off him, you tramps, he's ours now," said one of them, the same as before, with hair that was deep brown at the roots and paled out to blonde the longer it was. She had the bigger tits of the two as well, with a perkier and larger rack than her more evenly brunette partner. They both had a weird combination of duck face and resting bitch face that was largely not attractive. He could appreciate their bodies though, both crammed into tight bikinis that showed off their plump boobs and tight asses quite well.

Though he hadn't seen either of them since their infection and subsequent transformations, they still looked enough like themselves that Declan could tell the ombre-haired girl in purple was Lei and the pink bikini-wearing girl was Hannah. They had indeed stayed much the same, though the massive change in societal rules had apparently brought out their bitchiness in full ****. It certainly wasn't warranted; they were in no way sexy enough to pull off being so mean, especially compared to his sisters. In the meantime, they were standing over him and looking down at Vikki, who was still bobbing on his dick.

"Holy shit, Lei, look at the size of those tits. Hey cow, move it, that's our dick now." Hannah kicked Vikki in the side, pushing her away from Declan and letting his cock pop free from her mouth. She cried out in protest, quickly getting to her feet to stare down the other girls, chest and enormous boobs heaving.

"What the fuck? You can't come in here and just take what you want! Much less take Dec! As if he'd want to fuck you two with your shit attitudes. Plus your tits are so small I could - what's wrong with them?" Vikki stopped her tirade when she noticed both of the bitches were unresponsive and unmoving. Both their eyes were locked on Declan's erect shaft, not breaking focus in the slightest.

"Are they okay?" Cora asked after a minute of the girls not moving or responding to anything.

"No idea. Hey cunts, what's up? I know it's a pretty dick, but what gives?" Adeline said, shoving Lei a little. The ombre-haired girl didn't do anything to keep herself from falling to her knees, eyes still staring at Declan's shaft, though her breathing did pick up until it was almost raspy. "Okay, there's something very wrong with them. I've shoved them before and both of them lost their shit. They must...is she kneeling down on her own?"

That was indeed what Hannah was doing, slowly lowering herself so she was kneeling next to Lei, still staring fervently at Dec's dick. None of the siblings knew what to do, Declan least of all, but he knew he didn't really want to be stared at by the two bitchy neighbors. Taking upon himself to break whatever limbo they were in, he stood up to move, the action unintentionally putting his erect member right in the face of the two women.

Lei and Hannah both gasped in unison at the thing thrust in their faces, Hannah orgasming on the spot with her eyes rolling up while Lei breathed deeply through her nose. They both finally moved a few seconds later, both closing in on Declan's dick. He half expected them to do something terrible, but was pleasantly surprised when both of them gently kissed and licked the head, making cute little feminine sounds of happiness that he never would have thought them even capable of.

Seeing and hearing them whimper and mewl before him was so surprising he nearly missed as they started to change. Most notable was their clothes, the material of their bikinis multiplying and shifting until they were wearing nearly identical white shirts and shorts. Their hair shortened too, Lei's into a short ponytail and Hannah's cut at the nape of her neck. Their curvy bodies lessened somewhat, breasts receding as their skin paled a bit. Their faces lost their pouty bitch look and became much more 'cute/sexy girls next door', a pretty drastic improvement as far as Declan was concerned. The fact that the now cute girls were gently smooching and lapping at his cock like it deserved worshiping had absolutely nothing to do with it.

"Hot damn, what happened to them?" Cora asked, only to have her voice drowned out by Adeline's cackling laughter. She was hunched over, laughing her ass off, and didn't seem like she was going to stop. They all gave her a minute and eventually she calmed down, only to immediately kneel down next to Hannah and Lei and mock them.

"Hey cunts, where'd your tits go? You can't hope to get a man with such little beestings like those. Let's get those shirts up and see just how big they are!" She quickly grabbed the hem of Lei's shirt and tugged it up over her tits, then doing the same for Hannah. Neither girl seemed to mind; they continued to lavish Declan's shaft with their tongues and lips. "Look at those cute little boobies, you girls must be so proud! Maybe if you're good little bitches, you'll even get some cum. Does that sound good?" Neither girl answered, but both kissed at the cock in front of them with more intensity. "Just look at how pathetic you are! What happened to the big bad bitches who were going to come over and steal my brother? Did they slink away once they found someone who wasn't putting up with their shit? Or did you just need to be pushed down and put in your place?"

"I think I know someone who needs to be put in their place," Declan said, grabbing a handful of Adeline's hair and jerking her head back. She instantly gasped and arched her back, pushing her chest out for him and slipping into her submissive side. "Even if they are bitches, look at what a good job they're doing. They don't need you berating them while they enjoy sucking at my dick. You can do that once they're finished, okay?"

"'kay," Adeline whispered, looking up at her dominating brother with equal parts love and lust.

"She is right though, you two have lost a lot of your curves. Why don't you put my dick on your tits so we can see just how big they are?" The two women didn't waste a second and eagerly sandwiched Declan's cock between their chests, needing both of them to properly titfuck him. The sight of the two former bitches giving him an extremely enthusiastic boobjob with big smiles on their faces, combined with the feeling itself, was enough to make him cum, semen splattering out onto their bodies. The two girls squealed and came themselves, and then rubbed their titties together to smear as much of his jizz on them as possible.

"Alright, I want one of you on my dick and the other on my face," Declan said once the novelty of the sight had worn off. He didn't even really pay attention to which girl pushed him down and impaled themselves on his dick, the two sluts were effectively interchangeable at this point. It served them right, he thought, to be reduced to a nameless set of holes after they had treated everyone they met like dirt. Though his opinion might be skewed given how enthusiastically one of them was riding his cock. The other hadn't been slacking either, grinding her delicious pussy on his face and gushing into his mouth. Despite wanting to remain in control, he couldn't help but grab onto the thighs of whoever was riding his dick and thrust into her, making her moans that much louder.

His tongue was skilled enough to make whoever was riding his face cum and cum hard, pleasure wracking her body and making her fall off of him. It had the unintended effect of freeing up his mouth again, which he was happy to take advantage of.

"Vikki, could you come over here? There's not nearly enough boob over here and I need something in my mouth." The youngest girl was more than happy to offer her breasts to her brother, sighing happily as he started to suckle them. "Adeline, you come here too. I think you need to make up for insulting our guests," Declan said, his voice becoming more strained as he got the words out. He could only hold out against being ridden so hard for so long and finally spurted into the girl's cunt, cum gushing out of her. He freed himself with a wet squelch and Lei, who ended up being the one riding him, collapsed with a blissed out expression.

Adeline immediately went for her brother's dick, wet with his delectable cum, only to be stopped. "If you want cum, Ade, there's plenty right there," he said, and Adeline looked to see him pointing at Lei's leaking pussy. She didn't say anything, but shirked away, unwilling to eat out the former bitch of a girl. Declan didn't let her go far though and held her in place. "No, lick the cum out of her, Adeline. And if you do a good job, you can torment her and her slut friend however you want." Driven by her submissive want to make Declan happy and the promise of ****, Adeline reluctantly went to work, slowly gaining enthusiasm as the taste of semen soothed her. She'd **** Lei with this, she decided; bring her right to the edge and keep her there until she was begging for forgiveness and climax. She went to work with more enthusiasm, savoring salty jizz and sweet ****.
