Prince Charming/Sex Education - Theory

Time passes and most of school becomes routine. There are all the usual subjects, as well as horseriding, fencing and boxing. When you go home, it's still as depressing as ever. You have an interview with The King and tell him that everything at school is fine, but for the most part, you seem to be invisible.

There's a new Nurse and she's a lot younger than the old one. When she put you to bed the first time and you lay there on top of the blankets stroking your cock, she seems a little bit surprised, but she soon gets the idea and uses her mouth and tongue to get you off. The next evening, as she bends over, you slide your hand up under her dress and find her hot, wet opening with your fingers.

She seems surprised and stands up and looks down at you. Then, without a word, he strips her dress up over her head, leaving her naked. Her tits are quite small, especially compared with Matron, but you decide that they're better because they don't flop about so much when she's riding your cock.

Back at school, at the start of your third year and just after your eighth birthday, you see that there's a new subject on the timetable. Every Thursday afternoon, it says Sex Ed. You wonder what more there is to learn; Mr Romeo has found himself a new boy, but you been fucking Lance's arse a couple of times a week and Matron every Saturday evening.

You're surprised to find that the class is being taught by a nun. It's hard to see how old she is when you can only see her face and then she unrolls a big drawing of a girl showing all of her insides. "You may not think that a boy needs to know all this stuff," she says as she points out the fallopian tubes and the womb to ten giggling schoolboys, "but one day you're going to get married and then you and your future wife will appreciate it." After teaching you the proper names for all the different parts, she goes on to talk about the more common names like clit, cunt, pussy and arse.

The following week she does the same thing with a drawing of a man. Of course, we all know what a cock and balls look like, but it was kind of interesting to see the inside parts. She goes on to talk about puberty and how that will affect us. "I'm sure that most of you masturbate quite frequently," she says without a hint of embarrassment. "Some of you may find you get a little bit of fluid coming out when you climax. Put your hands up if you do." You and three other boys put your hands up. "Some people call that boycum, but it's actually semen. When you reach puberty, that semen will be full of sperms, but that won't happen until your testicles start working."

The next week, she talks more about what happens inside during sex. She has some pictures, like the cutaway drawings of machines showing the inside workings. But hers, show a stiff penis inside a vagina and she talks about how a girl's vagina stretch to accommodate a big one or squeeze down to make a small one feel good. "I'm sure you've all seen animals having sex and you know that with animals it usually over quite quickly. As soon as the bull ejaculates into the cow, he loses interest and then wanders off to find another cow. "As far as we know," the nun says, "animals don't really do it for fun and that's one of the big differences between us and them.

The next lesson is about differences. She shows us paintings of naked men and women in talks about how some are fat and some thin; some are tall and some short. "I know that boys like to compare cocks, and by now you will realise that they come in a whole range of sizes. Those of you with bigger cocks might be quite proud of them now, but when you get older you might find that for some girls, bigger is not necessarily better."

The following week, you're all sitting at your desks as she leads a young woman out in front of you.

"I want you to meet Annabel," the nun says. "She's eighteen years old and married with two children and she's kindly agreed to help us out with our lessons." She puts her hand under one of the girls breasts and lifts it. "See how her breasts have begun to droop a little, even though she's still young, and see how her nipples and aureola are quite dark compared with her pale skin." She moves on down the girl's body and shows us the stretch marks on her belly. "It's hard for a woman's body to stretch enough to allow a baby to grow inside her and some women end up with these marks."

She gets Annabel to sit up on the teacher's table and spread her legs apart and we all crowd round while she points out the different parts of her anatomy. "Pay particular attention to the clitoris," she says, and we hear Annabel take a sharp breath as the nun's finger stimulates her nub. "See how it swells up," she says. "Think of it as being a little like your cock and if you want to make your wives and girlfriends happy, you won't go far wrong if you concentrate on their clits."

She moves out of the way and we all take it in turns to rub Annabel's clit. Roger sticks two fingers into her vagina at the same time, making her squeal and earning him a clip round the ear from the nun. By the time we've all finished, Annabel's face had gone quite pink. We all moved back and the nun looks up at her and smiles. "Some of these boys are probably wanking two or three times a day," she says. "Why don't you show them how a girl masturbates?"

Annabel giggles a little self-consciously and then puts her hand down between her legs to stroke her clit. She rubs her fingers down between her lips and then back up, spreading the moisture around. "See how wet she is," the nun says. "I told you about how pre-cum works with a man, now you can see the woman's contribution to making everything down there nice and slippery. Annabel is biting her lip and her fingers are a blur as she works herself up to a climax.
