Julia enters the room

You hear the door creak open, and Julia enters. She is tall, blonde, and over all a perfect 10 out of 10 in your book; lithe, well toned muscles, large ass, and a huge rack of perky, bouncing tits. "I know its been a year since dad disappeared, but it is also your birthday. You can't always be down and gloomy that he is gone, he wouldn't want that. Hell, for all we know, he could be trapped on an island, or in some 3rd world prison waiting to get out and come home to us." she says as she walks across the massive bedroom over to your desk. "Look, I know you and some of the girls don't get along all the time. But this is just as much for them as it is for you to keep their minds off dad. Now come on down." she says as she grasps your arm and starts to drag you out of your chair.

"Just a sec Jules, I need to tell you something." You respond, resisting your sister's tugging.

She stops, and looks at you "What?"

"I got this email from dad when I sat down, it says he knew he wasn't going to be here for us, he also included some program in the email. It seems to be the real deal. Can I show you?" You ask her, almost pleading to her with your eyes.

"Wait, really? Yeah, show me!" she replies in a raised voice, obviously excited.

You spend the next minute reading the email to her, and then showing her the program.

"Does it really work?" She asks, leaning against the back of your chair, her breasts nearly rubbing the top of your head.

"yeah, let me type something simple out." You reply.

You toggle over to free-form writing mode and type out a simple sentence.

"Everyone on the estate really loves me."

You click "finish", then select the 2nd option, selecting that only Julia and yourself are aware, and click on "finalize". You feel a rumble, and hear a faint thump as new memories flood in.

You feel your chair quickly turned around to face your half-sister. "Wow, that feels weird." Is all she says.

"Holy shit, dad wasn't kidding when he said be careful. I think you made me bi, or at least attracted to you and women." She says.

You look at her, a little confused "What do you mean Jules?"

"I mean, look at what you wrote. I weren't specific. I think everyone here now loves you, not just familial, but actual romantic and sexual love. Fuck. I have the urge to suck your cock now. What ever changes we make, they need to be careful for now on." she says, licking her lips.

"We? What do you mean 'we'? Dad gave this to me." you object.

"Okay, and? Why can't I use it? It's not like I would harm you, I love you after all." is all she replies, pushing you out of the way, and starts to type something into the program. Before you can stop her, she finalizes the command, and you feel a low rumble and a soft thump. But nothing feels or seem different.

"Wh-what did you do?" You ask her.

"Nothing 'Big Bro'" she seductively replies, winking at you as she gets on her knees, an starts to pull your gym shorts down. "Just time for your Birthday Blowjob." she purrs, only to stop, and gawk "what the fuck!" she mutters, "How big where you before James?" She gasps.

"What do you mean? I've always had a two foot cock." You reply.

"Oh fuck, you where already hung. See? We gotta be careful with what is changed." Jules says. That last change I made it so your cock doubled in size, and cummed twice as much, as well as made it so everyone here is okay with ****." She then starts stroking the base of your think cock, as she starts to lick your cock head. After a minute or so, she starts to deepthroat your cock, taking as much as she can. You can feel her getting tighter around your man meat as it starts to harden.

You moan, and feel vibrations through your cock as Jules is trying to deepthroat your massive cock. She gets a full foot down when she pulls back, pulling your cock out of her, coughing as she does so, saliva and precum drooling from her lips.

"You know, having a cock this big sucks if you can't get a chick all the way down, you should change that." She rasps between gasps for air, also make it so I can at least breath if I need to. With that said, she plunges down back on your cock. The sensations make it had to think of something to type out. But you get there, reaching to this statement.

"Everyone is elastic enough to take my cock to the hilt without issue, no matter how they take it. Everyone can also take what ever cum load I give them without ill affects. My cum is also extremely nutritious and tasty. Anyone deep-throating me is able to breath through their nose still if they need air."

How does that sound Jules? Slap my right leg for yes, left leg for no. You feel a tapping on your left leg, so you enter it, and select only yourself and Jules as knowing about the change. Once again, you feel the familiar rumble and thump. You push back from your desk, Jules struggling to keep up. Once pushed away, you look down at her face, precum drooling from her mouth. You grab her head, and thrust the remaining foot of cock meat down her throat. You feel her throat vibrating, like she is trying to speak, but you don't know what she is saying. She tries to push back, but that sends you over the edge. You hold her tight as you feel your balls clench up, and your cock spasm. You cum load after load into her stomach. After about 30 seconds, you finish, and she slowly pulls off. Once only your cock head remains in her mouth, you can feel her tongue swirling around, trying to take the last spasms of cum, which would be entire loads for the average man.

She finally pulls free completely, her stomach is slightly distended, from what you can only assume is your virile and nutritious cum. You staring at your sister is interrupted by her "God, you're so fucking delicious. Fuck me, how was I ever just a lesbian?" She says between wiping her self clean with her fingers, and then sucking her fingers clean. She grabs your thighs, and uses you to lift herself up "come on Donkey Dick, lets get cleaned up and going, everyone is waiting for you downstairs."

"Donkey Dick?" You ask, pushing off from your chair, going to your closet to get a fresh set of clothes.

"Yeah, your hung like a horse, or a donkey, and it rhymes, unlike horse dick or horse cock." She happily replies.
