*****
Seven hells, it had happened. I'd made love to my sister, came in her, and now had her nakedness sprawled over the couch next to me. It was thrilling having sex with Jen: she was astonishingly beautiful with my cock deep within her and her skin flush with sex. I wouldn't mind going at it again, I thought to myself. The incredible idea that we might make a regular habit of our incestuous coupling came to mind.
"That was fun."
'Hmm," my sister replied.
Hmm... somewhat non-committal. Jen sat up, her brow creased - this boded poorly, I could just tell. Goodness gracious, she could be a fickle lass sometimes, a character trait I'd noticed many times growing up with her.
"We shouldn't have done that."
My dream of regular copulation looked fleeting.
"I don't understand you, sis. First you want me, then you don't. We make sweet, sweet love, and then you say we shouldn't have."
"I do want you, Alex - it's just wrong that I do. You're my brother, for God's sake."
"It's just a bit of fun, that's all. Nothing to feel all guilty about."
"Just a bit of fun?" said my sister, crestfallen.
"Not a just a bit - a lot of fun! Hell, it was life-affirming sex. Divine."
"Sinful, not divine."
"Semantics, dear sister."
My sister laughed and I breathed my relief. At that moment I heard the closing of car doors in the carport - our parents, returned!
"They're back! Quick, get your clothes on."
It was maybe ten metres from the car to the front door. I pulled up my pants, briefly catching my semi-flaccid cock in the zip, eliciting a howl. My sister already had her skirt on, so she grabbed her blouse then dashed up the stairs to her room, not bothering to button it up. I heard the key enter the lock; I had maybe ten seconds, so pulled my polo on and sat back on the couch, switching the TV to a commercial station. Late-night Turkish news, brilliant. The front door swang open and my parents entered the hallway.
"Hi Mum, hi Dad," I called.
"Hi," they replied, approaching the lounge room.
I noticed my sister's discarded bra on the floor and grabbed it, my heart racing, tossing it behind the couch just as my mother poked her head in.
"Hi Alex. You're up late watching TV," she said, looking at the screen. "Learning Turkish?"
Goddamn. "I'm just channel surfing during an ad-break. How was your evening?"
"Enjoyable, even if the company was a little dull. Is Jenny home?"
"Yeah, in her room I think."
I heard my parents walk down the hall to their room - we had managed to avoid detection that night, but it did highlight the risks of our forbidden lust: namely, being exposed, berated and potentially disowned. The risk of being caught with my cock in my sister's cunny - maybe that was part of the appeal of incestuous fantasy, but in reality it would be devastating to our family. No doubt Jen's fear of that outcome contributed to her seemingly capricious behaviour.
The following morning, Sunday, was our traditional day of sleeping-in. Even my parents would not rise until mid-morning. I awoke incredibly horny having spent my entire night dreaming of the previous day. My rational mind had determined that we'd need to be very discrete for the time being. After this week, well, we'd have an apartment to ourselves and be hundreds of kilometres from anyone who knew us. This presented exciting possibilities, but I needed to test the waters with my sister first. This meant more sex. To that end I woke shortly after dawn and slipped silently into her room.
My sister was in a short nightdress and although her room was dark I could still make out the enticing curves of her breasts and legs. I crossed the distance from the door to her bed, noted that her nightie had ridden up her legs as she slept, now barely covering her buttocks, and then crept onto her bed next to her, spooning her, my stiffness nestling against her butt. Jen stirred, still not fully awake, and her legs parted slightly, allowing me to position my cockhead against her slit, only the thin fabric of my cotton shorts between me and her. Putting one hand on her right breast, feeling out and circling her nipple, I began rubbing my erection against her. Already I could feel a moist spot form on my shorts, which I surreptitiously rubbed into her pussy lips.
"Ugh," she moaned. "What's going on?"
My sister awoke with my hot breath on the back of neck, the hardness of my cock rubbing along her cunny and my hand on her silk-covered tits. She tensed but did not push me away.
"What are you doing here, now?"
I continued playing with her nipples through the thin fabric of her dress. They were hardening at my touch, poking against the diaphanous material.
"Enjoying you, that's all. Mum and Dad won't be up any time soon, I thought we could have some morning fun."
"Sleep is morning fun," she groaned.
"There'll be time for that when we're dead."
"And we'll be dead if Mum or Dad catches us."
She rolled over and looked at me, her pale blue eyes bright even in the darkness. Her hand slipped down to my tented shorts, hooked under the elastic and pulled them down, freeing my cock. My sister took it in her hand, still watching my face just inches away - I could feel the warmth of her breath on my cheeks -, and began rubbing.
"What did you have in mind?" she asked.
"This is a good start," I said.
Jen was slow and deliberate; I could get used to this. Maybe it could be a morning ritual when we lived together interstate - an enticing thought if ever there were one! Idly I wondered if she'd given many hand jobs before, perhaps to fellow backpackers in Europe and SE Asia. Or would she have treated them to more? Not content merely to have my sister's hands rubbing up and down my shaft, I thought up further baseness. I couldn't explain why, but baseness and my sister seemed to go well together.
"You're thinking dirty thoughts, aren't you? Naughty boy."
I scoffed, "What does that make you? A naughty girl? Or a very naughty girl?"
My sister smiled and her rubbing hastened. Pleasure was flowing from her hand up through my body, making my earlobes hot and my toes tingle. My rigid shaft was the conduit of this bliss. She was a virtuoso playing my instrument, possessed of a skill far exceeding my own in that respect; the irony that my sister could outclass me at jerking my own dick brought a wry smile to my lips.
"The naughtiest, of course."
I was breathing fast now and knew it was only a matter of time before her hot little hand would bring forth the flood. The gyrating heat of our two bodies on her bed fanned the fire in my loins.
"You're getting close, aren't you?"
I nodded. I wanted to last longer, I really did, but my eyes were locked to hers and my heart was racing and I couldn't think straight any more, let alone contain the pressure rising within my depths. My sister had a terrible effect on me. Maybe it was seeing the girl I had shared my entire life with a woman now, her sensuous form so close to me; I could hear her dulcet childhood laughter in the songbirds' morning verse. Or maybe it was the titillation as she twisted her hand softly, pulling up and down, electrifying the sensitive nerves in my member. Yet in the frantic energy of my need and her scintillating exertion, I felt tranquillity.
"That didn't take long," she said, her voice calling my consciousness forth from its idyllic depths.
