Naughty, But Smart Sister

Julia looks you in the eye, one hand groping her large tits, and the other holding Kayla's head to her pussy. Naomi is next to Kayla, sucking on Kayla's tits, and playing with her own tits and pussy.

"OH FUCK!" Julia lets out in a loud moan, smothering Kayla into her pussy, "Fuck that was good!" She moans out, coming down from her orgasmic high. She looks down at the two maids, and orders them "Naomi, Kayla, go fuck each other on Jasmine's bed for now." pointing towards your massive bed. "Hey big br- big sis" she says, eying you up and down.

"I'm not angry, but what did you change?" You ask, sauntering over to Julia, and sitting down sideways on her lap. "And what did you mean when you almost called me 'bro'?" you ask, looking deep into her eyes.

"Simple, you made some accidental changes to me, making me bi and incestuous, so I had to even out the balance some. But instead of me telling you, why don't you read the changes I made?" She replies, before bringing you in for a deep kiss. You pull away from your sister, and look at your monitor to read what she changed.

Julia Byron has natural breasts that measure 32N in size, and are perky, and keep their shape naturally. She also produces and can store an abundant amount of breast milk, similar to all Byrons that are futa or female.

James Byron is actually Jasmine Byron, and is a futa, a third gender that emerged around 200 years ago after a comet went through the upper atmosphere. Hir cock, balls, and cum output are not affected, but she does have breasts that are 34N in size, and produces and can store a record setting amount of milk just like hir balls can produce and store a record setting amount of cum. Jasmine Byron is extremely charming, and likeable, allowing hir to convince any man, woman, or futa to have sex with hir, or join his harem and/or employ. Any woman or futa would consider it a great honor to be impregnated by Jasmine. Jasmine and hir companions have an aura of normalcy around them, meaning people don't find Jasmine or hir campanions' actions out of the ordinary or note worthy. Jasmine and hir companions can toggle this ability on and off, or even selectively turn it on or off. If their are conflicting aura settings, the over all aura will go based off the highest members aura, with Jasmine at the top, followed by Julia. The order after that is at the discretion of Jasmine and Julia

The futa gene is extremely rare, requiring both parents to have the gene. If two futas produce a baby, there is a 20% chance to be a futa, 75% chance of being female, and 5% chance of being male, if one parent is futa, and the other is male there is a 5% chance for a futa, 65% chance of a male, and 30% chance of a female. If the parents are futa and female, the chances are 5% chance futa, 65% chance female, and 30% chance male. If the parents are male and female, the chances are 49.5% male and 49.5% female, with a 1% chance of being futa. If only one parent has the gene, the chances are 0.05% of being a futa, the male and female being equal. If neither parent has the gene, the chances are 0.0002% of being futa, and male and female being equal.

A futa and women are constantly ovulating. Fertility is only controlled by the inseminating party. Men and futa are able to control their fertility from sterile up to guaranteed pregnancy, or any probability in between. Impregnating a woman or futa when they don't want to be impregnated is considered rude, but not illegal. The inseminating party is expected to take care of the impregnated party and their child(ren)

Futa are known for being extremely well endowed in the size of their cock, balls, cum out put, breast size, and even milk production. Both males and females benefit from having the futa gene, men have larger cocks, balls, and cum out puts; while women have larger breasts, and milk production. In either case, neither still match up to futa.

No one in the Byron family or employ is a futa, but several have the futa gene, including all of the staff.

Large breasts still have their mass and heft to them, women and futa don't have any negative health issues caused by large breasts and their weight.

**** is not illegal, but it is still not encouraged between generations due to possible power issues, but **** between siblings and other family members similar in age is not discouraged. Pregnancies from **** do not produce any negative side affects for the child.

All Byron staff are hired due to their **** nymphomania, here they can choose to learn to embrace their carnal desires, or to suppress their condition so they can function in the world without much of an issue.

Jasmine will have no recollection of hir life before until shi reads this entry, and shi will not be bothered by Julia's changes.

Both Jasmine and Julia will know of any changes made, and can veto any change that would also change Jasmine or Julia with their mind. Neither party can change the other party without their explicit consent to the exact changes being made.

Julia, Jasmine, all of the Byrons, the Byron estate staff, and the staff's immediate family will no longer age if they are older than 25, and will stop aging once they reach the age of 25. All parties mentioned in the previous section are immortal, and cannot die unless they choose of their own free will to die, at which point they instantly die. Julia and Jasmine can at any point in the future reset everything to the point at which Jasmine has read the entire entry by saying, signing, thinking, or any other form of choice not mentioned the emergency code phrase "quoin clitoris sultry agnosia overplus alimony". Nothing can prevent either Julia or Jasmine from remembering or otherwise knowing the emergency code phrase. Once activated, the universe is reset to the point in time previously mentioned. Both parties will retain any and all memories and knowledge, but all other beings in the universe are reset unaware of anything happening.

You turn to look at your sister again. She has a large grin on her face. Behind her, you can hear and see Naomi and Kayla moaning into each other as they are 69ing each other. Your formally clean bed getting ruined by their saliva, milk, and fem-cum.

"So, what do you think Jasmine?" She asks you, looking right into your eyes.

All you can manage to say is "Holy Fuck Jules", shock and awe visible on your face.

"'Holy Fuck' good, or 'Holy Fuck' bad?" she asks, looking a little nervous.

You brush a few stray strands of hair out of her face, "Just 'Holy Fuck', neither good nor bad. Seems like you thought some things out, and decided to cover our asses so nothing bad can happen. Talk about a long entry, Jesus fuck." You feel Julia's hand snake down, under your skirt, starting to rube your thick tube of man, well, futa meat through your cock sock. "My only question is, where is the part mentioning my cock sock? Did you do that, or was that just an unintended consequence of your meddling?" You ask your sister, as you grab her hand, and use her hand to start rubbing your hardening cock.

"I didn't, must've been an unintended consequence." She replies, speeding up the rubbing. You cock starts to rise up, pushing your skirt up as your cock rises until it slaps against your huge tits, causing them to jiggle from the impact. you cock sock is stretched tightly over your thick fuck-stick. You keep jacking off as you lean in, and kiss your sister, pushing your tongue into her mouth. You can feel your cock throbbing in rhythm with your heart.

This continues for a minute or so, when you break off, catching your breath. "We gotta stop, I have to get ready for the lawyer coming in, she has all the paperwork to sign over the estate and corporation over to me from the trust."

"Oh come on, you have enough time to plow one or both of the lovely ladies on your bed." She says, giving you an exaggerated pout. "Besides, you're about to be at least her boss. She can wait for you. Besides, even if you are late, you can just tell her you where busy plowing, and planting your fertile seed."
