Seducing My Sister/First BJ/The Doctor

Every year, Mum insists I go for a checkup. It's a Friday afternoon and she collects me from school at lunchtime and we catch a bus. The surgery is busy and there's quite a few people waiting, coughing and sneezing germs. When we eventually get called, is not the usual doctor but an older lady with silver grey hair and steel rimmed specs. The usual checkup takes about five minutes: height, weight, blood pressure, hand under the balls and cough, and that's it. She wants to do more.

"This will take a while," she says, looking across at Mum who's sitting tapping her feet. "Why don't you can get a coffee in the café next door? I'll send him out when we've finished."

"Will you be okay," Mum says, but she is already on her feet heading for the door anyway.

"Right," the Doc says. "I know this might be embarrassing, but I want you to strip right off and lay down on the couch." You do as she says, thinking there's no point arguing. She gets a stethoscope and listens to your heart, then your belly, and he runs her warm hands down your sides, squeezing and kneading. "Well that seems all right. Now comes the embarrassing bit. You've nearly reached puberty and I want to check that everything works properly down there."

She spreads my legs apart and cups my balls, giving them a gentle squeeze. Then she catches hold of my limp cock which immediately starts to swell. You can feel yourself blushing with embarrassment. "Sorry about that," you say.

She laughs. "No, that's fine. Exactly what I wanted to see." She starts sliding the skin up and down. "Do you masturbate a lot?"

You gulp and shrug. "What's a lot?"

"Hmm. More than once a day?"

"I guess."

"I can see that your penis is a little bit sore. Maybe you need to take it a little more gently. The trick is to squeeze on the upstroke and not to pull the foreskin down too far." While he's talking, she's demonstrating and it dawns on you that you're lying on a couch in the doctor's surgery while she is wanking you.

"Should you… err… Be doing that?" You can feel your balls beginning to tighten and you know that if you keep going it won't be long before you cum.

The Doc keeps going with a nice rhythmic stroke and the inevitable happens. She keeps hold of your rapidly deflating cock and then scoops some of the cum off the end. She examines it closely, smells it and then pokes out her tongue to taste it. You prop yourself up on her elbows, watching with astonishment.

"Hmm. Excellent," she says. "I think it's important for little boys, once they start to take an interest in sex, to have some proper guidance. I run a weekly session on Tuesdays at my house for a selected group. Would you like me so ask your mother if you could come. We call it Key Stage Three tuition.

Your brain is reeling with what happened and all you can do is nod your head.

A few minutes later, still a bit dazed, you head towards the coffee shop where Mum has organised hot chocolate with marshmallows on top. "Everything all right," she asks.

You shrug. Yeah, sure." No way are you going to tell her the Doc just tossed you off. "She said something about extra tuition on Tuesday evenings. She's gonna talk to you about it."
