My sister Kim was 7 years younger than I, and thus we did not have a lot in common. When I hit puberty she was starting school. When she hit puberty I was in college. Oh, we shared the usual family things, birthdays, holidays, vacations and such. But our interests were years and worlds apart. Now and then I would help her with some math or science and I would answer any questions she would have about being grown up, but due to the age difference we rarely played together or watched the same movies or went places together. She was just the kid sister and I was her big brother.
When she was 15 and starting to get into dating she would ask my advice on how to handle various situations. She had not had a lot of experience and was curious, as are all kids that age. Kim was about to enter the period of high school when social as well as sexual items play a large part in a young girls life. It was also the time when your academic performance would determine what college you could attend, what kind of scholarships you would receive, and therefore likely set the tone of the rest of your life.
Kim confided in me that she did not seem to be as boy crazy as most of her classmates and wanted to know what I thought on the social versus academic question. Having just graduated from Penn State and about to enter grad school, I said, "Well, I feel the academics are highly important at your age, and there will always be time after high school to worry about the guys. And besides, most high school boys are so inexperienced and not yet refined in matters of the heart, which you really would not be missing a lot if you spent your time on the books and not the jocks."
This seemed to reinforce the way she was leaning on the subject, she said, "Thanks for the help."
Three years later, she graduated 2nd in her class with a full academic scholarship at a major university. I had just finished grad school and had a nice job lined up. So that summer we spent a couple weeks at our cabin in the mountains of western North Carolina before I had to go out and start working full time. Our folks were working in the city, but they wanted us to have this last time together before I started my new job.
The cabin was rustic and small, and Kim made a point of allowing me to catch a look of her nude a few times. I didn't think much of this, she was still just my kid sister showing off a bit, but what the heck, most any 25-year-old guy likes to see nude 18-year-old girls. Most every night after we had gone to bed, it was so quiet in that cabin in the woods, I would hear her moaning in her room a few minutes after retiring. I knew that my little sister Kim was not a little girl anymore.
One afternoon we were having a summer thunderstorm, so we were forced to stay inside with little to do. Kim said to me, "Can I ask you a question?"
I replied, "You just did" so she threw a small pillow at me. I said, "So what's your question?"
She replied, "Do you think that I'm pretty?"
I said, "You are the prettiest sister I have," and that got me another pillow.
"Come on now, be serious," she yelled, so I cut the joking and told her that she was above average in looks and that she was about fully grown now and would continue to improve as she got a bit older and a bit more self confidence.
We continued to talk about dating and boys and sex and masturbation. Kim confided in me that she had not had any sexual contact with any boys yet and was afraid that she would make a fool of herself the first time around. I assured her that we all have those fears before hand but when the time comes to just go with the flow and do what you feel like doing.
At this point she paused for about 20 seconds, and then unbuttoned the three buttons on her blouse and took it off and set it on the couch next to her. I wasn't sure what to say, so I sat waiting a bit, looking at her sitting there in her ice blue bra and mid thigh skirt. She looked at me, blushing a bit, and softly asked me if I would play with her titties.
I replied, "I'm your brother."
She quietly said, "But I want you to teach me what it's like."
"No, it's not right for me to do that with you," I replied. She just sat there for a minute not knowing what to do.
"Please," she said, "I need to learn, I didn't date a lot in high school, and I want to know what's what when I get to college. And besides who better to teach me than you."
I could feel my cock stirring a bit, even though I didn't have any sexual feeling for my kid sister. Yet here we were, sitting close to each other, and her bra and tits begging for some attention. I thought back to our discussion about boys and sex and school 3 years ago. Kim's breasts had grown since then, and it seems so did her interest in sex. I'm thinking about it, which no one would know, but just couldn't. "Look," I said, "I'm the quote adult here, and it's my responsibility to look after you, not take advantage of you."
A pout was on her face, and she said, "But you aren't taking advantage of me, you will be teaching me. And I'm 18 now, so I am as much an adult as you are. And," she continued, now with an almost evil look on her face, "if you don't do it, I'll tell Mom that you did."
I gulped, and thought about what she just said and her look while saying it. It was true that I would just be teaching her a few things, just like the math and science, and it was an awful threat she made, threatening to say that I did it if I didn't do it. "But …"
She snapped back, "No buts, I'll tell Mom you forced me. And if I do, there goes you car graduation gift, and the rest of your being a part of the family."
I was stumped, what was I to do. "Just what is it you want me to do?", I asked.
"I'm not sure, that's what I want you to show me, what boys do. What do you do with a girl when you are making out with her?"
Considering the situation and the consequences, and I knew that Kim would follow through on her threat, I said, "Well, OK, but I'm only going to teach you the early stuff, I'm not going to have sex with you, I'm not going to fuck you."
