3PB/SarahC/Bedroom/

You stand up, grab a towel and run off into your bedroom where you sit on your bed and rub yourself dry. Your nightie's folded up on the pillow but instead of putting it on you sit there and imagine that you can still feel Jason's finger inside you. There's a knock on your bedroom door and Jordan comes in with Jason who also seems to be wearing nothing but a towel.

"If you want to know more about grown-up sex, I can help, but only if you want to. If you say no I'll just put Jordan to bed, okay?" Jordan's standing in front of you with his arm around Jason's shoulders and you can still see where his cock is pushing out the front of his shorts.

You shrug; you're torn between wanting to know more and being scared, but wanting to know more is winning. He smiles and takes the towel off Jason, leaving him standing up naked in front of you. "The first thing is, you need to get used to seeing each other naked; it's one thing in the bath but it's different in the bedroom," Jordan says.

He stands there looking at you, and Jason reaches down to catch hold of his cocklet which is gone all droopy again. You can feel yourself trembling a bit as you unwrap your towel and let it fall on the bed behind you. "That's better," Jordan says, and then changes his attention to your brother. "Now, I want you to have a close look at your sister's pussy," he says and pushes Jason down onto his knees in front of you. The thought of your little brother looking at your pussy makes you giggle, but you open your legs so that he can get a really good look.

"A girl's pussy is quite complicated," Jordan says as if he's a teacher giving a lesson. He gets down on his knees beside your brother and points. You think he is going to touch you and you shrink back a little, but he's just pointing. "Sarah, open your legs a bit more." He orders. You hesitate, but only for about half a second. You want to do what Jordan says to make him like you, so you spread them as wide as you can. "That's better," he says, "now you can see the opening of her vagina. The vagina is where the boy's cock goes when you're having sex and, believe it or not, it's where a baby comes out of a mommy. Just above that is a smaller opening. That's where the pee comes out just like it comes out of your cock. And, just above that, we can't see it but there is something called a clitoris. Its where she gets the best feelings from when you touch it."

"How does he know all this stuff," you think to yourself but then he tells Jason to reach out and touch you. Jason has moved so close that you can feel his breath on your pussy and then he pushes two fingers straight into your vagina and it makes you jump and whimper a little. Jordan tells him to be gentle; "a girls pussy is very sensitive; if you get rough with her she'll just get cross and you won't get any further."

Jordan's kneeling down beside Jason and explaining to him how to rub gently and in a way that makes it feel good. After a bit, you realize it is starting to actually feel better than when you rub yourself. Even though it is your brother, you are starting to like it a little, so you lean back and close your eyes and pretend it's Jordan instead of your gross little brother rubbing your privates. A bit after you close your eyes, a finger touches you closer to the top without Jordan saying anything, and then you realize that something different is happening. "You know what I said about the clit," Jordan says. "This is where it is and if you stroke it, you can make it swell up just like a tiny cock." Jason's finger is still inside your pussy, but now you can feel another finger touching your sensitive spot and you guess that must belong to Jordan.

The sensations the two boys are giving you are becoming almost too much to bear and you fall back onto the bed and push them away with your feet.
