your older sister(Futa Dom), super charged super computer

your sister Maya always looked out for you and took care of you but you could always tell she had quite a chip on her shoulder. She was definitely on the heavier side even more than yourself but she was smart she built her own computer in a shed in the backyard she said it could change things like what someone thinks or remembers but "only small things"- she would say and you would add new parts to the computer to make it just a bit better (add a fan or to hook up another computer and throw away parts) when she and your mom would work, but a supercomputer doesn't play well with eclectic bills every time she would use it it would add 100 dollars to the fee. now that you are 19 and have just been fired you would have enough money to ask to use it in a way you could gain from. while you were looking at your ceiling thinking about what to ask for when a loud noise from the backyard grabs your attention. As you and your sister go out you see a pink block with gold microchip lines going through it. you both come to the same conclusion "Let's see if we can't hook it up to the supercomputer" Now in all other situations it shouldn't have worked at all let alone just by putting it on top of the computer. when you placed it on the computer thinking how to connect the darn rock it "melted" and spread across the janky tech. when it was done it had removed its plug and had a pink text saying

"upgrades installed alter at will

instructions. "

"whoa let me read this," said Maya you had to look over her shoulder to try and read but you can only pick up pieces with how you have to bend and that Maya is a faster reader than you "This device can alter reality ... further updates ... chooses who knows ... can swap, grow ... and do as you please... change history.. all at your fingertips "

" Can we really change reality," you say "Well only one way to find out Billy" replied Maya as she typed in pink letters [ I am now 6ft tall ] as she pressed Enter a pink bolt jumps from the key and shocks her but you miss this " ouch stupid static shock " then as she hand in pain you saw she grew in height up to an even 6ft she then stopped what she was doing and looked her self over "I'm tall," she says "I should change something else " she quickly types [ Billy will be completely loyal to me and listen to whatever I say] " what did you put, " you ask "nothing big. say can you give me a lap dance," Maya said

"Sure," you say as you bend over and grind into her flat crotch " I don't know why you ask for them you don't even have a dick"

" need a dick huh" she types in [I now have a 6in cock I am the only one that notices that's weird] "Well now I do" as you feel a bulge push against your rump "Now I think a big dick needs a big ass" [Billy as a 50in ass] you then feel your ass grow and rip your pants as you both moan she jerks her hips forward and you feel her shrink after a few seconds then you sand up

"that was nice but can we not almost fuck again "

"oh " [ Billy loves me and shares my kinks and completely loves to be dominated and an always horny bisexual] "Why is that, think you won't be able to pull back next time," she says in a commanding voice. you blushed because she was right that you love this stuff " But what if anyone were to see us" Oh don't worry about that with this I can solve all those problems. for now how about you go to sleep and leave everything to me."

"okay," you say as you leave to go to bed and then jerk off and go to sleep horny for tomorrow.
