Monday Morning

That next morning Jack awoke and found himself on the cold metal floor of the machine. As he pulled himself to his feet, his body was stiff and strained due to the way he had collapsed onto the floor and slept. He slowly dragged himself out of the machine and over to the mirror he had set up in the study. As he held himself up against the desk for support, still getting used to his changes, he started to pick himself apart in the mirror. The first noticeable change that Jack had done to himself was that he now stood a towering seven feet, with an athletic muscular build that could be seen no matter what he wore. Moving downwards Jack had also increased his mammoth cock to be even bigger at a new flaccid length of 10 inches and would stand erect at 18 inches, giving himself a true horse cock along with softball sized balls. Jack had also made some unseen changes such as making his stamina now 20 times that of normal, as well as his cum production and volume, along with decreasing refractory period. But not only did he change himself physically he also made mental changes such as having a more dominant attitude and personality, as well as being more aggressive and assertive.

It was now late into the morning and Jack surmised that the Smiths had already left and his mother more than likely at work. So after catching his breath and adjusting to his new shape and size Jack slipped on a now tight pair of gym shorts before walking out into the kitchen. As he walked in he was greeted to the bountiful view of his sister wearing nothing but a sexy French maids apron hugged her front tightly but left her back completely exposed, while she washed the dishes. With a grin on his face Jack slowly approached her before giving her ass a hard smack, causing her to let out a moan of pleasure as she stepped back against him.

"Oh Jack you're up, why did you not come back to bed last night", Olivia said in a soft voice as she continued to clean the dishes.

Jack only grinned as he reached his hand around and started to slowly grope his sister's large breasts, causing her to freeze up and start to moan. His sister then pushed her plump ass further against him only for her to then say "Jack... I can feel that you're ready to go".

Jack let out a soft chuckle before saying "I am not even hard yet slut". This caused his sister to let out a gasp in-between moans as he continued to **** her tits. About five minutes passed until Jack finally let go of his sister's breasts, which we now beat red, before he quickly put one arm around her waist and the other hand gripping her neck. As his sister caught her breath her sternly yanked her head back before whispering into her ear saying "I have made some changes... and from now my little fuck slut... you are going to refer to me as daddy... sir... or even master".

Emma could only mewl in her brothers tight grip as she gave a slight nod yes and said "Yes... daddy"

Jack smiled at his sister's response but before he could continue his fun with Emma the doorbell rang causing the two to quickly break apart. Emma quickly rushed up the stairs to hide or change, with Jack following behind to quickly put something more appropriate on. The doorbell rang again causing Jack to pick up his pace as he tried to pull a t-shirt over his now larger muscular frame. Once finally dressed enough Jack sprinted back down the stairs and over to the front door where he was greeted to a puzzling surprise. Standing in front of him was none other than Evelyn, all Jack could do was stare blankly as his mind tried to find words to say. This only led to Evelyn getting the first word as she asked "Hey, I am... um... Looking for Jack?", as she stuttered between words and averted her eyes.

Jack smiled at her question, realizing that she did not realize it was him, so he responded by saying "Oh Jacks not home right now, but you can come in if you want".

Evelyn gave him a quick glance up and down before saying "No... no I think I am good, just tell him to give me a call when he's back", before taking a few steps back and rushing away. Jack could only stand and watch as the petite girl rushed away blushing, he knew his next step would be to finally return to the reason why he built the machine and changed himself in the first place. Finally stepping back inside and closing the door behind him Jack thought it wise that later that evening he would give Evelyn a call, but for now he had a slutty sister to train.

That Evening

After taking his time to dominate and train his sister Jack finally sat down on the living room coach, while he left her a slobbering mess of cum and sweet upstairs. As he sat there he flipped out his phone, checking the time he knew his mom would be home soon, but that was of no worry as he started to call Evelyn. Sitting in silence as he let the phone ring once then twice and then finally he heard the click as Evelyn picked up saying "Jack! It's good to hear from you".

"Hey Evelyn, I was told you stopped by earlier" Jack said, trying to play innocent to his plan.

"Ya, I know it's been a while... but I feel sorry for what happened two weeks ago, and I wanted to invite you over" Evelyn went on to explain.

"I would love to come visit Evelyn, what time and day" Jack quickly responded.

Evelyn paused for a moment before saying "How about tomorrow around 7, that's when I get off work".

"I will see you then" Jack said before exchanging goodbye with Evelyn and hanging up the phone. As Jack sat there he knew tomorrow would be fun as he had no intention of directly going after Evelyn, at least right away. He was planning to arrive earlier and hoped Evelyn's mom was home, they had not interacted since Jack was in middle school, so there was no way she would recognize him, and he could just make something up.

Jack then waited for his mom to come home, and once she was he quickly started his domination and training of her as well. Before they all collapsed and fell asleep that night he would have asserted his dominance over his family and set in stone their new dynamic with him in charge. But falling asleep that night Jack was no longer concerned about his dominance over his family as he plotted to conquer another.
