Seducing My Sister/First BJ/The Doctor/Swimming/You/Lesson

The Doc lives in a flat above the surgery and you have to go round the back and up a flight of steps to knock on her door. She is wearing a dressing gown and you wonder if she forgot you were coming, she just leads you through to a room at the back. There's a big TV screen on one wall, and a leather couch facing it. There's some bookshelves with books and tapes and a low table in the middle of the floor. There is a window, but the curtains are drawn and it's quite warm.

"The trouble with sex education in schools is that there is no practical," she says with a smile. "I think it's my duty, for the benefit of future wives and girlfriends, to educate boys. Your mother and I have been friends a long time and she knows all about my, err, interests. She knows that you are starting to take an interest in girls and she asked me to to make sure you know what you are doing."

You're sitting nervously at one end of the couch and when she sits down beside you, you notice that you can see an awful lot of leg through the gap in the front of her dressing gown. "Have you been practising what I showed you in the surgery the other day," she asks. You nod. "I'm going to show you a little film and then I want you to demonstrate," she says, reaching out and picking up a remote control.

The people in the film aren't speaking English, but there are subtitles. They'd never allow a sex education film like this here. It starts with a couple of teenagers walking in the woods and holding hands. They've got names like Greta and Ake and they are in love.

There's a lot of stuff about how sensible they are etc, but eventually they get to a nice grassy place and start kissing. Soon Ake has his hand up Greta's jumper and soon after that she's tugging his jeans down. Greta is really pretty, with small perky tits and a cute bum. Ake is also pretty and he has quite a big cock which gets really stiff when Greta sucks it. The film says that foreplay is important.

After she sucks him, he starts sucking her. We don't get a close up of his tongue on her pussy, but he has his head between her thighs and she certainly seems to like what he's doing.

While you are watching this, the Doc has managed to get your trousers and boxers off. Just as Ake starts sucking Greta's pussy, the Doc starts sucking your cock. She's really good at it and you cum almost straight away. She uses the remote to stop the film. "Time for a break then," she says.

When she stands up, her robe is open all the way and you see her big tits and get a quick glimpse of her pussy. She comes back with drinks. Yours is Coke, but you can smell the gin in hers. You are naked apart from your shirt and she starts undoing the buttons. You stop her and just tug it over your head. "You're a very handsome young man," she says, looking you up and down. You can't help blushing like a girl.

When she starts the film again, she fast forwards through a lecture about safe sex and stuff, to where Greta helps Ake put a condom on. They start off with her on her back and him on his hands and knees. She has to guide his cock into her vagina, but once it's in, he starts fucking in earnest. After a minute or two, they swap over, with him on his back and her on top. The film suggests that for first-timers, this is a better position. They finish with her on her hands and knees, and him kneeling behind her, fucking her like a dog on a bitch.
