It's about what Chad wants for Natalie

If Chad's doing this, then he's going to do it. "I just want you two to be happy," he says, and he's not totally lying. He looks at his girlfriend, standing and presenting herself. She'd do anything the man said, even if it ruined her. He knows what he has to do so that she's not just used up and cast aside. First off, Natalie, do you understand that what I do here is going to change you until you're basically unrecognizable to your friends and family? That no one you know will believe that you actually are who you say you are outside the people here? Are you really okay giving up your old life because you're unable to explain to any of them why you look completely different, just so that you can feel my Dad's dick even once?"

"Get on with it," Chad's dad says, rolling his eyes, not realizing what changes his son is making.

Chad waits for Natalie to nod, apparently getting more excited by the second. "Okay, time to make you into something worthy of my dad. Natalie, do you, now, have the proportions of a teenage weeb's wet dream, with melon sized tits, and a huge bubbly ass?" he asks, thinking back on his own fantasies from his teenage years. Immediately she does. Chad adding the present tense, though, keeps the changes from being retroactive, which means that her clothes don't change to fit. She cries out in pain as her bra and panties dig into her skin. Chad hurries to add, "Did my sister see this coming and put you in slutty goth-y clothes?" and immediately her clothes change to match. She's in a black and pink checkered skirt and a black band shirt cut so that it scoops down deep over her cleavage.

"There we go," Chad's father says with a smile. "Now we're getting somewhere."

Chad nods and gulps. "And, uh, your hair. Is it now in a super long and thick, high, all black ponytail? Do you not grow any hair below your eyebrows? Are you short and pale, with perfect soft skin? And your face... Do you have the sexiest face my dad has ever seen?" and she does.

"Wow, kid, I didn't know you could be vague like that. That's something else..." he says.

Chad's mom looked at her in disapproval, which surprises Chad from how open she has been about sharing her husband. Maybe Natalie's becoming a threat.

"Is that all, Dad?" Chad asks.

His father bites his lip and eyes her up and down, then agrees. "Alright, girl, let's see what you're made of. Start with your mouth." He pushes his chair back, leaving Camila under the table, gasping when his cock is pulled from her throat.

Natalie looks down at the massive thing nervously. She sinks to her knees and shuffles forward with Chad's whole family watching. Looking at him for permission, she wraps her hand around it at the middle and points it toward her face.

"Quit just looking at it," he says impatiently. "Hey kid, she knows what she's doing, doesn't she?"

"Uh, yeah Dad. I don't think she's done stuff like this before, but she's naturally the best you've ever had, right?" he asks, worried that Natalie will be cast out looking like a whore with nowhere to go. And also, that same sick part of him is compelling him to see the girl he loves do this right.

With a new confidence, Natalie shoves the cock deep down, taking half of it in the first go. The slurping sound tells everyone how hard she's sucking, like she's trying to make it come to her instead of the other way around.

"Woah!" Chad's dad says, bucking forward in sudden stimulation. But Natalie isn't deterred. She keeps sucking, bobbing her head back and forth, taking it deeper and deeper each time. She wants nothing more than to take his cock, and she's determined to have it. Saliva bubbles up around her mouth and drips down into her new tits.

"What the fuck, kid, where'd you find her? Shit, I might get her again just for head. This is awesome!" His dad grins. Her lips leave streaks of dark purple lipstick going further and further down his shaft.

"You might have to train her in everything else because she's never done anything before, but you like that, right? If you're starting from scratch like this you can make her the best you've ever had, can't you?" Chad asked. There, that gives her some time.

"I like your thinking kid! Yeah, let's see what you can do. Get up here, Nat." He pats his lap, inviting the girl to sit on his cock. It takes a little non-verbal help, but he positions her so that her tits are facing him. She puts her arms around his neck, puts one leg over his lap, lines up his cock, and presses down.

It's like everyone is holding their breath, as his cock presses against her lips. It's not like she's not wet enough, but more just their differences in sizes. Finally, when she presses hard enough, it shoots inside of her and she cries out.

"Is it good?" Chad asks, acting quickly to take away the pain, but he's not sure he needs to. His father knows how to handle her perfectly. Even though he's letting her take the lead, Chad can tell that his father is making it as comfortable for her as possible. It seems altruistic, but you can tell it's not. It's just part of the training process.

"Her first time, and it's on Dad's dick? She's never going to bother with anyone else," Lucy says. "At least I had a few first and I remember how fun a normal one is. She's not even gonna feel one like yours." It occurs to Chad that in this new reality, his sister has probably seen his dick quite a few times.
