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 for the holidays, life in the castle is 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. Sex Ed, every Thursday afternoon. You wonder what more there is to learn. Mr Romeo has found himself a new boy to wank over now, and you are fucking Lance's arse a couple of times a week and Matron once a month when she does your medical.

You're surprised to find that Sex Ed is being taught by a nun. She unrolls a big drawing of a girl showing all of her insides. "You may think that a boy doesn't need to know all this stuff," she says as she points out the various parts like the fallopian tubes and the womb to ten giggling schoolboys, "but your future wives and girlfriends 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 boys look like on the outside, 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 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 can 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."
