So why do you pick Roger? You decide you're going to tell Dale the reason, but first you have to make a few more adjustments on the computer. The first one of those is that Dale is turned on by the idea of men fucking you and risking impregnating you. And then you make the chance of herself getting impregnated by them a big turn-on for her too.
You beckon to her, and she crawls over to you, nuzzling your thigh. Finally, she understands you want her to stand up and kiss you, so she does so slowly, kissing her way up your body to your mouth. Once you've enjoyed it long enough, you tell her the news.
"We have to get pretty for Roger, my lovely fuck toy. He's coming over."
Her eyes return to the round, wide-eyed stare you've seen on her face so many times now. "Roger?"
"Mm-hm. I feel like fucking him again."
"Again?"
"Again. Back after Tina was born, you were too busy fucking around with the girlfriends you made while I was pregnant. So I found some fuck buddies of my own. Roger and his wife."
Her mouth falls open, then you tell her the rest. "Did you know his middle name is Geoffrey? And his wife's name is Tiffany. They fucked me a whole lot more than you did, sweetie, and he's Jeff and Tiffa's real daddy. Probably. There's a few other candidates, but the odds are it's Roger. I know it's not Lamar. That was a stupid risk, letting Lamar cum inside me, wasn't it? No way I could explain away a black baby."
Actually, the stuff about Roger and Tiffany was true, but you never had sex with Lamar, although you're going to give him the memory that he did you several times. But talking about it is having a satisfactory effect on Dale. After kissing her again and fondling her stiffening nipple, you whisper into her ear, "Thinking about them filling me up and giving me their babies? That make you horny?"
She nods slowly. But then she asks an important question.
"Will Roger know it's me?"
You stare at her for a moment, then giggle. "I hadn't even thought about it. I better check."
And it turns out she has a good point. The program only did what you asked for. You find out a 'reality compensator' needs to be turned on to automatically adjust for the changes you made. You have to bring up the manual tool, or Roger will be looking for the old Dale and Stacy and wondering who this pair of twins are.
The tool is pretty easy to use, though. All Dale's and your stuff is now right for eighteen year old girls. Although once you think about her trying to wear the clothes, you give Dale some skills at dressing in it and make some sexy improvements to both your wardrobes.
At Dale's insurance agency, they think the business was recently sold to a pair of rich twins, and they never think about the old owner. All your official information is adjust to show you two born eighteen years ago today. And from now on, most people have forgotten about the old Dale and Stacey. Your family and friends remember you and understand you are the same people, and they all consider your transformation into 18-year-old twin blondes as a secret they aren't allowed to ask about or pry into.
You take care of the changes you made to other people more simply. Everyone thinks everything is normal except for realizing the changes to themselves and their husbands or wives.
And because you're finally thinking about other people, you remember your kids. Jeff's D&D night is now an all-nighter at a friend's house, Tiffa's doing a sleepover with friends and Tina… you smile and decide she's going to accidentally fall asleep and stay the night after wearing herself out having sex. With whom? She doesn't currently have a boyfriend. You decide she's going over to her best friend's apartment and will end up in a multi-hour threesome with the girl and her boyfriend.
And finally, every single person in the above list now wants to fuck you both, even the ones who remember Dale the middle-aged guy.
"Now we get ready," you purr at Dale, then shut down the program and hide the disc.
Get ready for what?
