Emma's Corruption

Later that night Jack was still up sitting in the living room watching movies while he had left his mother, a sloppy mess and covered in cum, passed out on her bed. It was around 10:00 pm when the front door opened and his sister Emma came storming in. As she walked into the entryway and up to her room you could hear the loud click of her heels on the floor and her emotions coming out in disgruntled huffs and puffs. When he heard the loud slam of her bedroom door Jack paused the movie and made his way up to her. He could hear sobbing and then soft screams into a pillow coming from Emma's room as he got to her door. Giving it a light knock Jack then said "Emma? is everything ok?".

She let out another scream into her pillow before saying "Just leave me the fuck alone you little shit".

Jack paused for a moment before opening the door, Growing up their home always had a open door policy so none of the bedroom doors had locks. As he entered the room Emma was on the bed with her face under a pillow as she continued to sob loudly. Jack was about to say something but was quickly cut off when his sister threw the pillow at him and then yelled "I said leave me the fuck alone, you fucking pig".

Jack let the pillow fall against him as he walked over to the bed before taking a seat. He sat there for a moment with Emma refusing to look at him until he said "Just tell me what happened Emma, I am still your brother, talk to me".

They both sat there in silence for a time while Emma calmed down, still refusing to look at her brother. Once she finally regained herself she turned to look at him, and said "My boyfriend dumped me, after all the time we have been together he dumped me". Emma began to sob again, but not before Jack pulled her into a warm hugging embrace, letting her cry into his shoulder.

Jack let his sister vent as she went on to explain the events of the night and how her boyfriend broke up with her while they were on a date. It would be during this venting and conversation that the topic would slightly turn back home and those recent events. She started to explain her frustration in what Jack had done to mom and the Smiths, but also let slip her sexual frustration on the situation as she said "Maybe my boyfriend would not have dumped me if I was hot".

Jack latched onto what she said as he then asked "Do you want to be hot Emma". But she only turned away blushing as he said that, causing him to ask again "Do you want to be desired Emma". Emma's face began to blush even more red, but then Jack asked again "Do you want me to change you?", causing her to let out a faint yes. Jack then paused for a moment before asking "Yes what Emma".

Emma's face was now red as a beet as she turned to face her brother and said "Yes, I want you to make me like mom, Olivia, and Ms. Smith".

Jack looked at her with a happy smile before saying "Follow me", Emma gave him a light nod before following him down to their fathers old office where the machine was. He then started to give a quick and simple explanation of the machine before asking her what she might exactly want. Emma blushed before starting to list off changes like bigger tits and ass, then fuller lips, a tan, but overall more full figure. Jack only gave her a smile while he started to punch commands into the computer, and once done directed her to strip. Emma rebuked his order for a moment before he explained that it must be done for the machine to work, so she reluctantly did so. Once she was striped Jack guided his sister into the machine and then powered it on by entering the start command. Knowing that the machine would take some time to change his sister Jack headed back into the living room to finish his movie. Eventually he heard the machine power down and returned to find his newly improved sister sedated inside. Jack carried her back to her own room where he laid her to bed, and then returned to his own room where after a long day Jack collapsed onto his bed and passed out.

The next morning Jack awoke to the softness of lips around the head of his cock. As he rubbed his eyes open he was shocked at the sight of his sister Emma with the head of his cock stuffed into her mouth. Once she noticed that he was awake she gave him a wink before pulling off his cock and sitting up. She was wearing a tight fitting pair of lingerie that hugged her new plush curves. Jack had tried to give his sister everything she wanted along with some added personal tweaks such as her being more submissive, overall more plush, more willing, and overall a craving for his cock.

Emma sat there smiling at him, patiently waiting for him to say something or command her. Jack grinned back at her before saying "Do you like the new you, Emma".

His sister blushed before saying "Yes, I love this new body, but now I have cravings, but maybe you could satisfy those".

Jack looked deep into her eyes seeing the lust that was in them and how intently she looked at his mammoth cock. Jack pondered what to do for a moment before saying "Why don't we have some family bonding sis, would you like that". His sister nodded intently, still refusing to look away from his cock. He grinned at her response and then told her in a commanding tone "follow me", which she happily did. Jack led his newly improved sister out into the hallway and then into their mothers room where their mother was still sleeping. He then commanded Emma to get on the bed and quietly start playing with Amanda, which she obediently did as she crawled onto the bed next to their mother.

Jack sat down in one of the chairs in the large master bedroom and watched as his sister started to slowly feel their mother up and down, before moving onto more sexual acts. Emma slowly caressed her mothers curves before slowly moving her onto her back. She then started to teasingly play with her mothers large breasts and nipples, sucking each tit before slowly kissing her way down to her mothers crotch. It was when Emma started to teasingly play with her mother that she finally started to stir, and once she had fully awoken and noticed what her "new" daughter was doing she yelled out "Emma, what the fuck are you doing!".

Emma looked up at her mother with her mouth still on her vagina giving her a devious look before starting to suck and lick harder. Amanda let out a soft moan, before finally looking out around the room and seeing Jack sitting across from them, watching the scene play out with his legs spread wide and let his hung cock hanging down. Amanda bit her lip before saying "Oh Jack, did you finally use the machine on the little slut". Jack only gave her a nod as he continued to watch what was happening, somewhat signaling for things to go further.

As Emma continued to eat away at her mother increasingly sopping wet pussy Amanda placed her hand on her head, driving her face further into her plump pussy and causing her to moan out in more pleasure. It was not long after that Amanda's breathing became heavier and her grip hard, that she finally threw her head back and screamed out in pleasure as she came from her daughter eating her out, and gushed all over her face. It was after her mother let go that Emma came up for air, taking in deep breaths before slowly crawling up atop her mother. The two voluptuous women started to then lovingly make out with one another, unable to resist the desire to taste one another.

That's when Jack finally stood up from his chair and walked over to the two thick women on the bed, before reaching over and giving his sisters ass a hard slap, causing her break from the kiss and moan in pleasure. The two women then returned to making out as Jack stepped up onto the bed behind his sister, and then slowly peeling of her tight panties. He then gave her ass another smack before spreading her thick checks and plunging his face onto her dripping wet cunt. Emma let out a soft moan into her mothers mouth as Jack started to eat away at her.

Jack eventually brought his sister to her own orgasm as she broke from kissing her mother to scream out as she gushed all over his face. Once Emma cooled down from her high Jack moved her off of their mother and flipped her onto her back. With both the mother and sister now laying next to each other Jack lined the head of his cock up with Emma's wet pussy lips. Looking down into his sister's lustful eyes he said "Are you ready to be my slut big sis".

Emma looked back up at her brother and then back down at his cock before saying "Make me yours... Daddy".

Jack looked down at her with a puzzling look before his face pulled back in a devilish grin as he thought about what she just said. Maybe this new family dynamic called for a change in dominance in the household and the way things were done, but ether way it was time to fuck the shit out of his sister. Jack gripped on either side of her hips as he started to slowly thrust his cock into her pussy, causing her to moan out in pleasure. Amanda rolled over pulling Emma in for a kiss and embrace as she placed a hand over her daughter's stomach. As Jack continued to thrust into his sister he eventually hilted into her as his cock bulged up causing her stomach to distort. Pausing for a moment letting the slut get used to his size. He then began to thrust in and out, increasing in pace with each thrust until he was smashing down into her sopping wet cunt, reshaping her insides to perfectly fit his huge cock.

The three of them continued to partake in a lustful, incestuous threeway all morning until Jack finally felt himself ready to blow his load. Pulling both his mother and sister off the bed and on their knees, he jerked his cock until he finally covered the two begging cum sluts in his thick seed. Once Jack finished cuming, both Amanda and Emma started to lovingly lick away any drops left in or on his cock before turning to each other and lick up his sweet baby batter.

Jack left his new two sluts to clean each other off in the master bedroom, and headed down the stairs to the kitchen to finally eat something for the day. He knew that his future would be filled with sex, but he began to plot his next course of action, what ever it may be.
