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.

"Lay down on the floor," the doc orders.

There is a sheepskin rug and you lay on your back, holding your stiff cock. She stand by your feet and shrugs her robe off. Looking at her naked body, you revise you estimate of how old she is. "She's the same age as Mum," you think as she kneels down astride your legs. Her skin is smooth and unwrinkled and her boobs are firm with long brown nipples. Her belly is almost flat and she has no hair between her legs.

She leans over and gives your cock a couple of sucks, before shuffling forward until her pussy is right above your cock. Then, with a big smile, she lowers herself down until her pussy has swallowed up the whole of your cock. Being sucked was nice, but the feeling of her hot, slippery vagina against the sensitive head of your cock is something else. She stays still for ages, just using some internal muscles to milk your shaft.

"Do you like that," she asks. You nod. "It's important to tell your partner what feels good and what doesn't," she says. "Too many people just bang away without really knowing what pleases the other person. You are young and have a lot to learn, but you will find that the best sex is when you give at least as much as you receive."

Lecture over, she starts lifting up and down, the lining of her vagina squeezing and rubbing and, of course, it's not long before that familiar feeling starts. "I, I'm cumming," you stammer.

"Let it come. Our time is nearly up anyway," she say. She rolls over onto her back. "You have to finish what you started," she says. She guides your hand to her slippery pussy and you start stroking it. "Put some fingers in," she orders and you bunch two, then three, then all four fingers and slide them inside. It feels warm and slippery and she holds your wrist to use your hand to get herself off.

After, she sits up and gives you a big hug. It's nice being squashed against her boobs and you hug her back enthusiastically. A few minutes later, she's all business. "Come on, get dressed," she orders, and you reluctantly do as you are told. In the hall, when you've got your shoes on and before she opens the door, she pulls you in for a kiss on the lips. "That was pretty good for a beginner," she says with a smile. "Maybe next week we can move on to oral."

You walk home in a bit of a daze. "I just had my first fuck," you think.
