Looking back on my life, I don't think I could have had a better one. I grew up on a small tropical island in the Bahamas - my loving parents the inheritors of a vast fortune - and spent my younger years being home schooled with my older brother Dean and traveling all over the world.
My parents were young and athletic, mom having been only twenty when she had me, and as such were full of energy and enthusiasm for life. They are also very liberal when it came to nudity, and growing up there would be weeks that none of us would wear a shred of clothing, freely displaying our tanned and toned bodies in the hot tropical sun.
Not surprisingly my mom and dad loved sex, and though they were never overt about it when we were younger, it wasn't that rare for Dean or I to walk in on them. I still remember the first time I came into the living room to find them doggie-style on the floor, dad's hard cock plunging into my mom's soaking pussy, her beautiful full breasts and long raven hair swaying in time with his thrusts. As soon as they spotted me they merely smiled, and without batting an eye asked for some privacy -- so I grew up thinking of sex as something completely natural, fun and loving.
Occasionally I'd even join my brother, spying on my parents as mom sucked dad's cock by the pool, or dad oiled up his cock and slid it into mom's ass, fucking her beautiful tight tush on the beach. On such occasions it wasn't a big deal to see Dean hard, and I had to admit I got more than a little wet watching my parents' antics. It wasn't until I turned sixteen, however, that I finally gained a true understanding of my mom and dad and the story behind our ideal family.
One night after dinner my parents called my brother and I to the beach for a talk. Dad lit a small fire, and we sat around it as the stars came out.
"Kids, there's something very important we want to talk to you about tonight," mom started, her sensuous naked form bathed in the light of the fire. "At first it may shock you... perhaps even disgust you... but I think once you get used to the idea you'll see it as something wonderful."
Dean and I looked at each other, perplexed. "What is it, mom?" my brother asked.
Mom hesitated, then taking a deep breath said the words that were to change my life. "Kids, you father and I... we're siblings."
It took a few seconds for the meaning to sink in.
"You mean, you're brother and sister?" I asked, my eyes wide.
Dad nodded. "Your mom and I grew up much like you two, very close and loving. And when we were about your age..."
"...your grandparents gave us the same talk we're giving you now," finished mom.
"They were brother and sister, too?" gasped Dean.
Mom nodded. "And so were their parents. Our family has been practicing incest for three generations now. You could say we're a very close family."
"But what about Aunt Karen and uncle Kent?" I asked, my mind reeling from the revelation. I knew that my aunt and uncle were swingers, but I had no idea just how kinky their relationship really was.
Dad smiled gently. "They're our younger brother and sister. As you know they decided not to have children, but nevertheless they kept with the family tradition."
For a moment Dean and I were silent.
"So... did you have sex with them too?" my brother asked.
Mom nodded. "Oh yes. Plenty of times. And with our parents too. When all of us were old enough we enjoyed many wonderful times together. We're a very special family, and now that you're eighteen, Dean, we wanted to give you the option of continuing the line, as it were."
Dad turned to me, and I couldn't help but notice how hard his cock had become. "For you Leona, sex will have to wait a couple of years. It's a family rule that you can't participate until you're eighteen. But we wanted to include you in this discussion because if Dean is interested... well, you might find us enjoying each other from time to time."
"You mean I can fuck mom?" Dean blurted out. His cock was now hard too, and it didn't take a detective to figure out just how much the whole concept was affecting him.
"And me too," Dad grinned. "We're a bisexual family, so nobody gets left out of the fun once they're of age."
My brother nodded dumbly, and letting out a giggle mom got up and moved to his side. "I've spotted you and your sister spying on us from time to time," she laughed. "And sometimes I noticed you watching us on your own, jerking off as you watched your dad fuck me. How about letting us give you some relief? I bet you've fantasized about joining in lots of times."
