"If I had to choose, it would be Tiffa," she admits.
"So it's both really?"
"Yeah, but you can't be both, so… Tiffa."
She looks embarrassed, which is cute, so you tell her, "Play with yourself while you fantasize about her."
She obeys, having to learn about fingering herself with some coaching from you, but eventually getting herself going with a steady rocking motion. You ask, "What are you imagining doing with her?"
"Sucking her titties," she says with a giggle. "Since I can't have my first choice."
"Your first choice?"
"I always fantasize her sucking my cock," she says, then giggles. "I can't believe I admitted that."
"I bet you cum in her mouth too," you suggested. She giggles again and nods.
You work the computer a bit, looking over Tiffa and making a few improvements before you change your body into a duplicate. Dale never has to know about the slight midriff flab you just relocated to her breasts, or the scars on her legs. And since you don't feel like having the bush she has, even temporarily, you just made it so that neither you nor your daughters ever have to shave again.
"You make her swallow it?"
"Well yeah," she giggles, wriggling as she feels up her own titties. She's breathing hard again now.
Finally, you change your body into Tiffa's, then slip down onto the floor with Dale. "Hi, Daddy. Wanna eat my pussy?"
"Let me suck your titties first, sweetie," she says, and you climb over her in a 'titty 69' so you can nurse on each other.
The taste of your own nipples in your mouth is wonderful, but also the sensation of Dale greedily sucking on her daughter's tits. She's into this like she's wanted it for ages, you can tell. You finally reach up with one hand to her pussy and find it dripping wet, so you begin fingering it vigorously. Finally, you crawl slowly down her body until you can slip between her legs and she can begin eating you out as well. The one thing Dale always was pretty good at was pussy-eating, and with a small, dainty mouth and no stubble, she just got a lot better at it.
She had a big head start on you, so she cums long before you do. She tries to rest, so you shove your pussy into her face and make her get back to work. Of course, you reward her too, continuing your own lovemaking of her cunt. It's a really pretty one, too. You'd had no idea how sweet a piece of ass you were at eighteen.
Finally you cum, grinding on her face almost enough to suffocate her, but of course she's used to it and manages. You rock and roll for a long time before you're done. Then you crawl down and slip in between her legs to finish her up for another orgasm.
You crawl up and slip into her arms for some snuggling. After a while, you pout and say, "I guess I can't stay Tiffa though. You've already got a Tiffa."
"But I can't fuck her," she says.
"Mm. You wanna?"
"You mean the real one?"
"Yeah. You wanna fuck the real Tiffa?"
After a long pause, she admits, "Yeah."
You giggle. "I think I wanna, too. How about Tina?"
"Yeah."
"Me too," you admit. Then you say, "I'm serious, you know. We're totally gonna do it."
You both laugh. Then you decide what the next move should be.
