Brainless Bimbo

You can't believe you're saying it. How quickly life has gone from normal to complete sexual depravity. Carrie likes the suggestion. She moans and slips her fingers between her thighs. "I like it. I want to see the look on Cassidy's face when she arrives and sees that her sister, who she's looked up to all her life, has become a brainless object meant only for fucking, don't you?"

You do.

Carrie tugs at your pants. "Then we have to make it so, don't we? And she's right. Plans are made. Cassidy is invited and agrees to come visit in a week's time. "Can you get the whole week off work?" Carrie asks. "I think for every moment of the next week I should be in a state of penetration, and you should be here to oversee it, you know?"

And that offer is hard to refuse... actually it's impossible to refuse. The next day you call work and tell them you're feeling sick and you might be out for a while. You and Carrie go shopping and get an assortment of dildos, butt plugs, anal beads, also makeup, blonde hair dye, bubblegum pink lipstick. Carrie prepares herself for you, making herself look dumb and cheap, and then you fuck.

As your cock shoves deep inside her, your girlfriend moans and whimpers. "Mmmmm fuck me stupid... yes... I'm only made for fucking..." at first it takes you by surprised but, as with all things that are happening, you get used to it quickly. By day 3 she's saying things like "fuck my brains into mush... I don't need brains, I just need holes."

When your cock isn't inside her, something is, usually the butt plug. She sleeps in it. She eats only cum. "To keep you nice and skinny." you say. Turns out you take to having a brainless bimbo doll quite well. "It pleases me to see you skinny and hungry. And you exist only for my pleasure."

You edge her constantly. She squeals and begs you to cum. "Your pleasure isn't important." You say.

"Of course not.." she admits, "I'm just dumb holes."

Over the course of the week, your need to adhere to basic human decency erodes, as does the light behind Carrie's eyes as she looks at you lovingly, obediently.

You worry a little bit that by the time Cassidy arrives you'll be so far down the rabbit hole that you won't be able to enact any type of plan. This was after all, originally just supposed to be a ruse, a trick, a fake lifestyle to help seduce Carrie's sister. Somewhere along the way it became real. You look at Carrie, her eyes glassy, her pink lips parted as your cock thrusts into her asshole. You wonder if she'll even recognize her sister when she walks through your door. She's done nothing but spread her legs and suck your cock almost constantly for 6 days. You're not sure what happens when Cassidy arrives.

But the moment comes whether you and Carrie are ready for it or not. Your hearth pounds. Carrie is dressed in a frilly push up bra and panties. She's still rocking the blonde hair, the makeup, and of course the "USE ME" tattoo. The door opens. You think you're prepared but what you see takes you by surprise.
