Introduction:

Carmen offers to mitigate her brother Josh's greatest regret.

Composed could no longer describe us. There, trapped on the mountainside with hot volcanic ash streaking down through the sky we faced our own uncertain deaths. There was nowhere we could go and we knew it. Nobody knew where we were and time had all but expired on out hopes of a rescue.

Trapped by a treacherous landslide and now metres below the trail we found ourselves marooned on a rocky outcrop hundreds of feet above ground level. Regardless of which path we might have chosen to risk our lives on there wasn't enough time to outrun the volcano. Had it not been for the peril and distress we were feeling we might have taken note at that moment of the most prolific view imaginable. One could see endlessly from there to the dim orange skewed horizon.

My sister Carmen was crying at that point and so too was I. For 5 minutes we consoled each other. I held my older sister in my arms as she rested her head on me. I kissed her forehead gently and then she raised her head up to the sparkling discolored sky. "Is there anything you wish you had done Josh?"

I was silent as Carmen rambled on and she answered her own question. "I wish I had gone to Paris with my friends last year instead of staying with Jeremy…" she looked truly disappointed, "He never cared about me. He only ever wanted sex", she explained solemnly. That comment got me thinking about my own failings in life.

There was no sense in being bashful I thought and I answered her forthright, "I wish I wasn't a virgin... I never had much luck there" I explained. She was flabbergasted, "You never once-" "Never", I answered before she could finish. "I never in a million years thought we would both die on this family vacation", she lamented. I hung my head down in defeat. We were both young and kind. How could this be how it ends? "We don't deserve to die like this", I said bitterly.

A few long moments passed before Carmen sat up completely, "You can fuck me... if you want to". Now it was my turn to be flabbergasted. Carmen went on, "I was always mean to you… I didn't expect you to say anything that was still possible just now". She turned her body and proceeded to pull down her yoga pants and panties all at once!

I had never ever had an unnatural thought about Carmen. To make matters worse she had always teased me in spite of that. Exiting the shower in a towel she would scold me as I passed by, "ewww, pervert!". I was always a perfect brother though and this reconciliation seemed to add up in my scrambled, near death logic.

At that moment I flung wide a psychological door. A mental pandora's box seemed to jar open. For the first time I could see Carmen was in fact a beautiful woman. She was only a year older than me. She was 5'6'' and about 90 lbs soaking wet. Here she was on all fours presenting her young ass as a sort of peace offering. Beautiful folds encompassed her pussy in a dazzling display of smooth skin and toned features. She appeared like a goddess over the lifeless landscape.

Around us on the mountainside streaks of red carnage were falling to the earth and igniting small fires. Just as Carmen started to feel self conscious and turned her head for a response I was dropping my own pants. "Holy shit!" Carmen blurted out. "Josh?" Her eyes were bugging out of her head staring at my crotch as she said, "you're huge!".

I got on my knees behind Carmen. Roughly 30 seconds went by as I tried to arouse myself. "I don't think I can do this", I shamefully admitted to her while frisking my limp manhood. At this point Carmen's act of selflessness had devolved into something much less compassionate. She wanted nothing more in the world than to take the biggest dick she had ever seen inside herself before her tragic death.

She was singularly motivated by something primal now. Carmen needed to feel her pussy stretched to its limits as the big dick behind her plowed into her loins. In a lustful haze she made an angry groan and spun herself around. She grabbed onto my tool and took me into her mouth with haste. There was no time at all to waste and it was evident in Carmens frantic maneuvers.

Carmen set about sucking my dick as though it could somehow save both of our lives. Hands were cradling and groping my heavy sack as her tongue raced around my stiffening cock head. We were both sweating profusely now and our hurried pace was making this hotter. Her mouth was succeeding where my hands had failed. From a limp piece of meat she had transformed my flesh into a rigid combative weapon.

Her face pulled off my dick with an audible pop. "Now!" She yelled as she spun around and bared her heavenly bottom to me again. I shimmied up behind her until my hard cock was pointing between her thighs and into her tight stomach. Leaning back I grabbed my manhood and lined it up precisely into my sister's fleshy labia. Her pussy was swollen and I struggled to get my big tip past her tight entrance.

Carmen winced as I fit my dripping mushroom tip inside her. We were both breathing rapidly as her body began adjusting to my goliath member. I was very slowly gaining ground while maintaining the pressure into her. Pushing steadily I was determined to bury my bone inside of her tight and fertile young body.

The heat was unbearable and her entire back glistened under what little Sun shone through the lightless skyline. I was now penetrating my own sister. Driving my cock up inside of her bent over figure. I was going to fuck her full of my cum. She was to be mine. My first ever.

Carmen was unbelievably tight and extraordinarily wet. It didn't seem to hurt her as I pushed onward, but the resistance was tremendous. She was as tight as I was big. Tugging my meat out and thrusting up into her had gotten me close. I hammered up into her again and again. "Umphhhhh", she said methodically as I finally buried my cock fully into her vagina.

She was stretched further than her pussy had ever been stretched. At least that's what she thought as she reached her first orgasm. I continued jutting up into her as her pussy clamped down on my cock like a python. Had it not been for the falling flaming debris, or my own impending death, well I would have cum right there and then. I was no different than anyone else their first time. This situation however, was very different.

Unable to reconcile the circumstances before me, I could not cum. So I fucked her as hard as was humanly possible. It was hotter than hell there and I embraced the Hell. I pounded Carmen in her box while she literally screamed out loud at the top of her lungs, "Oh! Oh! Oh!". With every thrust she moaned powerfully.

A few minutes before we had both been screaming for help before we realized nobody could hear us over the rumbling of the volcano. Now we were both screaming with pleasure. Down through the landscape my sister could be heard "Oh, oh, oh, harder Josh!".

My throbbing penis was splitting my sister in half. Shoving in and tugging out of her as fast as possible. It had been a dozen minutes and my fingers were digging into her hips as I thrust maniacally. Her pussy was fully dilated and had completely accepted me.

I was savagely owning her on the mountainside beneath a darkened sky. Her face was coarsely pushed into the rock as her hands dug into the thin soil and held her whole body from falling over the cliffside. We were both looking out over oblivion as I fucked into her. I had never felt anything like it. I had never seen anything more beautiful than her sparkling nude body bouncing back and forth as my slick hardened cock impaled her.

The size of my cock looked almost comical slamming into her small body and moments later she came again. Gripping my giant cock with her orgasmic contractions, I was bound again in her perfect hole. I lost it. All was lost and all seemed to be gained all at once. Not until I completely let go did I completely reach elation.

I didn't bother to inform Carmen, I just came straight up into her like she was my mare and I was her stallion. I started pumping and pumping cum into her wanton body in spurt after spurt of thick white jism. "Fuck!" I screamed toward the valley below. Carmen was totally my bitch now as she cooed primal sounds "Ooooh!". My hot seed flooded through her pussy and spilled into her womb. I loved my sister and in that moment we were bound as one.

Carmens pussy was still in the final clutches of orgasm clamping down on me through waves of pleasure when in front of us a helicopter ascended into our view. No more than 30 feet before us now they were climbing in altitude and a man descended from above. I pulled my cock out of Carmen and a river of our combined juices leaked out of her pussy onto the rocks.

I had just taken my hands off her hips as she took the man's hand in hers and he wrapped an emergency harness around her. In an instant she was repelled up and then a few moments later the same was done for me. I entered the helicopter buck naked. My sister was already covered by a blanket and was crying in her hands.

"You two are very lucky to be alive! We haven't had a landslide in over 60 years" the man who'd brought us up said. "The volcano! How long until it erupts?" I frantically asked. "Erupts? No. It does this a few times each year. It's just releasing some pressure, blowing off some steam. But you two know all about that don't you?".
