Not till much later did I realise she had planned it from the beginning, though, of course, it seems obvious now.
"She" was my elder sister -- elder by a year and a bit -- and her name was Anya. She was (at the time of this story) twenty, and I -- eighteen and three quarters. She was tall, almost as tall as I am, and slim, dark with long black hair and elegant limbs. She moved like a gazelle. There's no other word for it.
We lived, you must understand, in a fairly conservative society, though it's less conservative now than it used to be. What this basically meant is that, in those not-too-long-ago days, we had very little opportunity for sex unless it was within marriage. Even the privacy for groping someone of the opposite sex may have been difficult to come by -- and if you came by the privacy, it would be likely that you couldn't find someone to grope and to grope you.
So, given our ages and the fact that we had access to porn (porn always manages to find its way into any society, and the more conservative it is, the more its appeal) just gave us a further hormonal surge. Since my sister and I were usually rather open with each other, not the usual elder sister bossing younger brother scene, we did talk about what turned us on and we used to discuss how we would go about sex if ever we had the chance.
Still, I had never actually anticipated having sex. It was something in the future so far off that we could never contemplate it as real or of any immediate urgency. I used to fantasise about making love to an unknown, idealised woman, and masturbate. Sometimes (Anya's room and mine shared a common wall) I could hear gasps and soft moans coming from her room, and I deduced that she was masturbating too, but I never mentioned it. It was somehow indiscreet of me even to admit to knowing this about her.
One day our parents announced that they had to go to a distant relative's wedding and they would be gone for six days. They gave us all sorts of detailed instructions what we should do and what we should not do and so on. Everything was explained and laid out -- our every action while they were gone. We were both attending the local high school and at the time it was going to shut for a week long recess. We knew of this but never told our parents of it -- just in case they decided to cancel their trip to keep an eye on us, or, even worse, make us go along.
Can you imagine what it meant -- six days of freedom from under our parents' thumbs! We didn't actually think of throwing wild parties (we weren't even the sort who knew people who would come to wild parties) -- but we could imagine them, right?
To cut a long story short, the great day finally dawned and early in the evening the parents (with a last set of instructions to us) drove off. We were back from school, and supposed to get stuck into homework, but of course school was off from the next day.
Anya closed the door behind us, leaned on it, and breathed out audibly. "Whoof!" she said. "I thought they would never leave!"
I looked at my sister and grinned. "And so they've gone," I said. "So now that they went, what do we do?"
