To the bathroom.

You sneak off to follow Abby. When you get to the door, you find it unlocked. You turn the knob and let yourself in and lock the door behind you. Abby is already getting naked.
"Hey Daddy. Can you help me get my bra off? The latch is always so tight with these mountains on my chest." And what mountains they are. They each seem to be larger than her five and a half foot frame, definately bigger than the minimum specifications.
"Sure...honeyboobs," you try. You manage, with a lot of effort, to get the latch undone.
"Daddy I like it when you call me that, heehee." She seems programmed with a basic history with empty variables to fill in. You suppose you will have a similar history with them all.
"My ball bra too, please," she says as she bends over. She looks over her shoulder and bites her lip lightly. Her large round bubble butt juts out at you, bumping the hard cock in your pants. She eyes you just standing there. "Come on, Daddy," she says, almost a whisper, tempting you. "Make me naked. Just slide your hand between my butt cheeks and dig out that clasp."
You pause a moment longer, then reach between her cheeks and slide your hands around until you find the clasp she spoke of, positioned over her hole. You end up needing to dig your fingers into her hole to get at the other side of the clasp, which you then manage to undo.
"Daddy, you can take your fingers out of my bottom now..." she whispers again. You look up at her. "I know helping me wash turns you on, but let's let Mom take care of you like always?"
"Uh, sorry, Abby," you trail off.
"Get your clothes off so you don't get wet, remember?" Abby chides you.
You quickly strip down and put your clothes in a pile. While you did that she sat on the edge of the basin, facing inwards. Her balls overfill the entire basin. Her tits are stacked on top of those. Her massive cock is draped over her neck like a boa.
"Ready Daddy," she looks at you, your hard cock nearly poking her face. "Daddy you aren't going to have an accident again, are you?" She eyes your dick.
