I still don't know how it started.
Well, I do know how, I just don't know why, or even how I let it.
I mean, it's not something I'd even considered before, much less taken part in.
And it's not as if it was a family tradition, as a matter of fact, I really can't imagine any member of the extended family would believe it had happened if we told them.
Dad has a good job, he's an account executive with a major advertising agency, and he earns enough to provide us with a nice house in one of the leafy, more affluent suburbs. My parents like to spend most of their free time entertaining; we've always got some sort of party or barbecue happening on Friday or Saturday nights.
Our house is comfortable, but not ostentatious, it's specially designed for entertaining, with a large pool and deck, and an enclosed barbecue area.
That's how it started, really, at one of our regular Saturday night pool parties.
And that's another thing I don't understand. He's not even my type.
"He" is my brother David. He's 19, and attends college. He has his own apartment, thanks to a part time job he has, and a scholarship. I'm 18, still at school, and still living at home, with my folks.
I'm just a normal 18-year-old girl, not stunningly attractive, but passable, I guess. I know there's been a few guys commented on my long legs, and a few more on the uptilt of my breasts being so pronounced. But it's not like I'm like one of those model types. I've had a very normal sex life, groping in the back seat of a car at 16, only two serious relationships, the second of which finished due to terminal boredom several months ago. I don't see myself as abnormally sexual. I masturbate maybe once a week, sure, but that's normal.
I have had sex once or twice when in a relationship, but nothing way out. And sure, I'd orgasm more often than not, but no one could have predicted this would happen.
And, as for David, like I said, he's not even my normal type. I'm more into the football player type, you know, muscular and heavy set. But David is a swimmer, and has a swimmers body. Long limbs, and long, sinuous muscles. He has a narrow waist and smooth, almost feminine skin.
Because he spends so much time in the pool, he is deeply tanned, and combined with his dark hair and long lashes, he appears almost cat like. And the way he prowls, rather than strides, only serves to add to the cat comparison. As I said, not the type that normally attracts me at all.
Anyway, it started at one of our folks Saturday night barbecues, on the pool deck.
David was home for the weekend, and we'd been fooling around all night, splashing and throwing blow up balls at each other, and generally behaving like absolute idiots.
Most of the guests had gone, and we were just lying back relaxing, when he dropped an ice block from the drinks bar right on my bare belly as I lay there on my back.
I jumped up in fright, catching him off balance, and knocking him flat on his ass, where I jumped on him, knocking the wind out of him.
"You bastard" I laughed, "you'll pay for that"
"Oh, yeah?" he laughed back, "and exactly how will you make me pay?"
As he spoke, he tossed his hips, attempting to throw me off, and I immediately grabbed his wrists, holding them behind his head, on the decking.
I moved my ass back to stop him arching his hips up again, and as I did so, I felt as if I had backed onto an iron bar. His erect cock poked me right in the pussy, sending a shock through my whole body. The surprise was so great, it made me jump, and I slid back even further to avoid the contact.
This made things even worse, because now, the iron bar spread my cunt lips wide, and what was obviously a very swollen head came in direct contact with my clit, through very flimsy swimwear.
There was one of those moments where time stood still, neither of us so much as breathed.
Then, very slowly, almost imperceptibly, David looked me straight in the eyes, batted those damned long lashes of his, and slowly arched his back, making his cock slide the full length of my open pussy lips. And not only once, either, but five times, very slowly, and very deliberately.
I was transfixed at first, but then reality hit, and I jumped up and stepped back.
"You bastard" I said, "You fucking pervert, how dare you?"
The bastard didn't bat an eyelid at my protests; in fact he just smiled at me and winked, and said, "We'll see, we'll see" then turned and walked inside.
The next 3 days were hell for me; I didn't know what to think, or what to say.
On one hand, I had to admit the feeling of his cock under me was such a turn on. But on the other hand, he is my brother, for Chris sakes. And incest, God, what was he thinking? What would our folks, or their friends think?
In the end, the turmoil was getting too much for me, so I decided to front him about what had happened, and clear it up…. and make sure it never happened again.
So I waited until our parents were out visiting, and sought him out at poolside, where he was doing his daily laps. I waited for him to finish, and said in as strong a voice as I could muster "I think we need to talk about what happened the other night"
The bastard just looked at me the same as he had that night, and said, "Why, what happened?"
"You know quite well what I mean" was all I could think of saying, to prevent the embarrassment of actually having to specify what had occurred.
"Look" he said, "before this gets complicated, let me explain a few things, just sit down," he commanded.
I meekly complied, all my bravado destroyed by his calm manner. "So, explain away" I stammered.
"OK" he started "It's like this. Since I've been away lots has changed for me, I've seen life outside our suburban existence, I've studied Philosophy, and Sociology. I've come to see that so much of what guides us, and the rules that bind us are just so much bullshit, especially when it comes to sex"
"What happened the other night was nothing more than a male being excited by the touch and feel of a female, and the female responding in a like manner. You're an attractive and desirable female, and I had the urge to fuck you"
His usage of that word in my presence sent another shock through me. Never in my life had he uttered such profanity in my presence.
