Andrew sits on the end of the bed looking at us. Susan rolls on her side and whispers, "<small>I think we need to give him an anatomy lesson</small>". You giggle and she sits up and pulls her skirt down over her knees. “Janet and I are going to teach you about girls. Well, I’m going to teach you and Janet’s going to be my model,” She says and tells you to get naked.

Still giggling, you strip off and lay on your back in the middle of the bed. “Sit next to her,” Susan orders, and Andrew obediently sits up on the edge of the bed, while Susan sits down by your feet. “Right,” Susan says. “I want you to pay close attention to Janet’s tits. Just because she hasn’t got any boobs yet, doesn’t mean they’re not sensitive. If you put your hand on her chest, you’ll be able to feel where they’re going to be. Cup your hand underneath and squeeze gently. That’s it, now catch her nipple between your finger and thumb. Gently now.”

Of course, it's not the first time he has felt your non-existent boobs, but now, under Susan's instruction, you feel your nipples react to his gentle touch. “Now I want you to suck them,” Susan says. “Not too hard and No Biting, try and imagine you’re a baby sucking on your mother’s teat.” It feels pretty good, but it's a bit like being in a play, where the director keeps telling the actors what to do and you have to stifle your giggles.

“Now you can work your way down to her pussy,” Susan says. “Don’t be so impatient, the objective is to arouse her so much so that all she can think about is how much she wants your cock. Most boys only think tits and pussy, but at this point the whole of your sister’s skin is one big erotic zone.” When he puts his tongue in your belly button, it feels pretty weird, but nice weird. It's better lower down and you can feel his breath on your pussy as he kisses your mound.

Susan tells him to move further down and he spreads your legs wide apart so that he can kiss the inside of your thighs.

“Right. Stop there for a minute.” Susan goes into teacher mode and  points to your pussy, now fully exposed. "There is a lot of confusion about what things are called," she says, and you wonder where she gets all this from.

She puts the tip of a finger into the opening of your vagina. “Pussy is one of the nicer names for a vagina," she says. "But pussy is really the best name for the whole area from the mound at the top to the vagina at the bottom."

"You hear a lot of other names. Cunt, fanny, twat, slit, snatch, fuck-hole, muff are just to name a few. There are three important parts: the vagina." She pushes her finger in again. "This is the hole you been sticking your cock in and also where babies come out." She takes her finger out and spreads the lips apart. "This is the urethra, which is where the wee comes out and this is the clitoris, or clit for short.”

“The clit is the most sensitive part,” she says as she moves her thumb up to your bump, making you jump. “If you look closely, you can see that it’s like a tiny little cock.” He peers closely while she pulls the hood back to show him. All kinds of sensations are shooting through your body as she lectures your brother.

She is telling him that he should suck pussy like it's an orange, and when he gets his head between your legs and starts licking and sucking you clamp your thighs on his ears and start climaxing. It goes on, wave after wave as he keeps sucking and trying to get his tongue into your vagina. In the end you have to push him off.

You look at him, with his face all wet from your juices and can't help giggling. "You haven't finished yet." Susan says, and you both look at her, puzzled. "Turn over," she orders. ''"What now,"'' you think as you roll over onto your tummy. Susan slips a pillow under your hips making your bum stick up. "Isn't that a beautiful sight," she says, setting you off giggling again.

"I want you to give her a smack." You don't like the sound of that and try to get up, but Susan has her hand in the middle of your back, holding you down. "Not a hard smack. more like when you pat a dog," Susan says. You feel his hand lightly touch your bum cheek. "Harder than that. You want to leave a hand print but not hurt her. This time it stings a bit, and you have a sudden memory of Mother smacking you like that when you were really little.

"Now I want you to spread her bum cheeks apart so that you can see her bum hole." Susan orders. You lay there as he looks at your ass. "Now lick it," she orders.

The idea of Andrew licking the place where poo comes out is really weird and you try to wriggle away but Susan and Andrew both have a firm grip and then you feel his tongue tickling your bum hole.

"You have to forget any ideas about what's 'dirty'. When you are fucking, anything goes, so long as neither of you objects and you should only object if it hurts too much," Susan lectures. It's no surprise to see that she has the vibrator firmly buried in her pussy when you are finally allowed to sit up.

You are so hot after the lesson that you push Andrew onto his back and use his stiff cock to get yourself off and Susan joins in by sitting on his face so that he can use his newly learned technique on her pussy.
