Yourself

You sip your coffee staring at your sister and trying to organise your thoughts. Today is turning out to be a very strange day and it's not even lunch time yet.

"Well sis what am I going to do with you?" You ask the lifeless doll

You lift up her hand to study it. It's strange, it looks just like her hand but as you look closer you see that it is clearly a doll's hand. It is perfectly smooth. There is no sign of lines or blemishes, the fine hairs on the back of her hand have vanished and even her finger prints have disappeared. All of the skin you can see is like that cool and dry to the touch. When you release her hand it stays in position, sticking straight out in front of her.

"Huh, fully possible" you grunt

On a mischievous whim, you fold in all but one of her fingers. You bend her arm at the elbow and jam her pointing finger into her rubbery nose. You laugh at your silly prank, imagining all the names Zoe must be calling you inside her head.

"Ha ha, too bad little sister" you answer her unspoken objections "you're just a doll now. I can do what ever I like with you. That is what you wanted, isn't it?"

To make your point you reach across and grab her breast, squeezing it hard. The dolls breast feels soft and surprisingly real through the thin fabric of her top. Suddenly embarrassed you yank your hand back. You start to stammer out an apology but the doll continues staring straight ahead.

Worrying about the feelings of a sex toy suddenly seems silly. After all, she did ask for this. Finally, your curiosity wins out over your moral objections and you continue examining her.

You pull on her chin making her jaw hinge open. Her latex lips part revealing a row of perfect white plastic teeth. You can see her tongue in there and a dark opening at the back of her throat. Reaching in with a finger you find it to be warm and slightly slick like it's been lubed up already.

You find yourself wondering what it would be like to fuck Zoe's artificial face and the thought starts to make you hard. You unbutton her jeans and pull them down to reveal her plastic pussy. Like the rest of her, it is completely hairless and you wonder if that is a result of her transformation or if your sister waxes. It looks normal enough compared with others you've seen, all the usual folds and creases rendered in a soft pliable latex. You notice a sort of seam around the whole pubic region and realise that the pussy is detachable. You could pop it out and use it as a fleshlight if you felt like it. You wonder if she'd still be able to feel it if you did. You aren't sure if it would be hotter if she could or if she couldn't.

Aware that you are crossing a line but by now too horny to care you push a finger inside her. The fake cunt is slick with the same sweet smelling lube that was in her mouth. You smile wickedly to yourself. She is ready to be used and there is now no doubt in your mind that you are going to be the one to use her. The only question now is how you want to do it?
