The next day

The rest of the day had been a bit of a blur. Marcie had dicked down her mother and sisters multiple times, and her sisters had dicked her down just as much. A few more changes has followed, like making their cum taste sweet instead of salty, and giving everyone hairless bodies, and of course eliminating any chance that any of them could get pregnant by each other. She had also made it so that they only needed cum to survive, and they were sure to get plenty of it.

Marcie was awoken from her dream of having a harem of futa fucksluts by her alarm, to which she grumbled about, but soon remembered her busty mom, and she soon had a pep in her step. On her way downstairs to the kitchen, she passed by the open door of her parents bedroom, and the sight made her cock erect in an instant. Mary had Emma locked in a mating press, and was pounding into her with reckless abandon. it seemed the must have been at it a while, as Mary soon came, ropes and ropes of cum filling Emma's pussy. Mary pulled her cock out so that her tip was just barely out, then thrust in in one go again, causing Emma to scream out in ecstacy.

After eating her cereal, Marcie made her way back to her room. on the way thus time however, she passed by Jill's open door. There, lying on her double King sized bed was jill, who had her cock between her tits and was actively sucking it. marcie stared at her for a minute, her own hands working her cock, when she saw something that looked like her phone on Jill's bed.

Jill, did you take my phone? Asked Marcie.

Oh so you can't tell huh? replied Jill. I made my cock longer and my bed bigger.

To prevent further incidents like this, Marcie gave Jill's phone a copy of master PC too, though Marcie's could supersede Jill's.

It turned out that Jill had invited a few friends over for some 'fun'.

While they were waiting Marcie pulled Jill down onto all fours, and started fucking her lubed up ass. Soon the carpet was drenched in cum as Jill's cock leaked cum with each thrust of Marcie's cock. Soon she was also cumming, dumping load upon load in her sisters tight ass.

Marcie had pumped her 12th load in , and was almost ready with her thirteenth, when she saw a car pull up. She pulled her throbbing cock out of her sisters ass, which caused Jill to ejaculate and especially forceful and voluminous load, so much so that it splatterd all across her stomach and tits. Marcie walked over to the window and saw four people get out of the gray hatchback, a guy and a girl on the left side, and two girls on the right.

I'll take the two on the left, and you take the two on the right. Marcie said pulling out her phone just as jill did the same. They both quickly typed out that changes, and agreed to set it so that they only applied once they entered Jill's room. About thirty seconds passed, and the slutty sister's heard movement up the stairs.

The first, Sam was a short girl with mousy brown hair and no tits or ass, but as she stepped over the threshold to the room, she gained about 7 inches in hight, and her tits and ass ballooned out, and her hair became platinum blonde. She was now wearing a tube top and white latex trousers. The next to follow was Rachel, who became equally as busty as Sam, but was instead wearing a slutty police officers uniform. Finally was Anna, who upon entering gained the largest breasts and ass of them all, and was wrapped in a form fitting black dress, and her face was now decorated with makeup. She was wearing black lipstick and her hair was jet black with pink highlights and was hanging over one eye.

The last to enter was Jack, who gained not insignificant DD's and big heart shaped ass, and a huge 14 inch cock. While it was lacking in length compared to Marcie's and especially Jill's, it made up for it in girth. She, now Jackie, was wearing tight leather pants, and a too small t-shirt that exposed her ripped midriff, alongside a biker Jacket. Jackie looked at the cum covered carpet and said "Oh, you started without us" with faux indignation, already pulling out her thick cock, the piercing at the head glinting in the light. She moved over to Sam, and in one quick motion, pulled the latex trousers down, and began eating out her ass, with both of her hands groping and fondling the ditzy blondes globes of assmeat and causing Sam to moan, and her fingers to immediately move to her pussy. Jill meanwhile, walked over to Rachel and said "What's my crime officer, concealment of a deadly weapons" vainly trying to hide her 24 inch dick. Rachel tipped her sunglasses and bit her lip. Marcus meanwhile moved over to who was once Anna, but was now Raven, and grabbed her tits, which despite her seemingly stoic personality, immediate made her moan.

Soon the wet slapping sounds of sex sounded across the room. Marcie had pulled Raven to the ground and was sat in the edge of the bed, as Raven moved her tit up and down Marcie's cock, and lapped at the head. Rachel was riding Jill, taking inch after inch into her, and causing her stomach to bulge. Jackie also had Sam on the ground, with both hands on her head as Jackie thrust in and out of her with reckless abandon.

"Mmmmpgh, that's it Sammy, good girl".

The compliment seemed to please Sam, so much so that she orgasmed. Thus set of a chain reaction, and soon the sound of six sluts moaning and screaming in ecstacy filled the room, alongside the sounds of cum splattering. The dommy futa's swapped partners and began fucking anew. Marcie had taken a leaf out of her sisters book, and had Sam locked in a mating press, her heavy balls slapping against the beach ball sized globes that were Sam's ass each time she thrust in. She moved in to French kiss Sam, who had the whole bottom of her face covered in Jackie's cum. She sook felt the familiar sensation of her balls tightening, and came deep in Sam's pussy, and stopped a second to catch her breath, before begin the pounding once more.
