I awoke to soft fingers stroking my cock, tender caresses on my already throbbing shaft. It was still dark, though I knew, somehow, that it wouldn't be for much longer. The air in the tent was chilly, almost cold but not quite. It was warm to the point of hot inside the sleeping bags, probably had been before Dani started stroking me, but to be honest, I didn't really care much.
I opened my eyes to see Dani watching me, waiting for me to wake up. She smiled up at me and darted her face forward, quickly kissing me before slipping down, her fingers leaving my cock and brushing my cheek, trailing down my neck and chest as she went lower and lower. The sleeping bag went with her, uncovering me, allowing me to just see what she was doing. She looked up at me as her hand circled my cock and she lifted it, pulling it slowly towards her mouth. Dani licked her lips and softly pressed them against my cock, kissing just below the crown, letting them linger there as she stared up into my eyes. I felt and just saw her smile in the gloom, her eyes sparkling in what little light there was.
Her tongue slipped out, the tip exploring my hot skin. I moaned softly, barely a whisper as she dragged her wet little tongue lower, trailing it along my shaft before reversing and dragging the whole length of her tongue back up, maddeningly slow and deliberate. Her eyes bored into mine as her lips closed over my head and she sucked gently, her tongue wriggling against the corona. I reached out and cupped my sister's face, buried my fingers in her soft hair as I felt the concavity of her cheek against my palm.
She moaned gently around my cock, tiny little vibrations traveling down the length and into my balls. I felt her cheeks pull in farther and she used the suction to draw my cock in further, deeper. Her tongue dragged against the underside, rough and soft all at once against my shaft.
I curled my hand behind her head, fingers brushing against the nape of her neck as I felt her long soft hair tickle against my thighs. I bent my legs and squeezed her naked body between my legs, her hard nipple poking my legs, her skin warm and smooth and her mouth perfect around me. Dani's tongue made soft circles around the tip of my cock at the top of each slow, maddening stroke before she slowly pushed my length back into her mouth. She cupped my balls with one hand and slowly worked the other up and down my shaft as though she were chasing her own lips.
Dani sucked me carefully to the point of climax, building me right to the edge before somehow sensing it and backing down just enough, just the right amount to keep me from exploding.
"What are you waiting for?" I whispered, more curious than angry. I have never and will never be angry with a woman for wanting to suck my dick longer.
I felt her smile around my cock, and in the slowly brightening morning light I saw her hold up one slender finger. I fought back a moan as she shook her head with me still in her mouth. She swallowed my length again, pushing my cock almost all the way into her mouth and dragging her tongue along the bottom again, enjoying the little game of pushing me to the edge. She slowly pulled back up, circled the head with her tongue, her hand twisting as she stroked.
I heard Mom and Dad's tent flap unzip and would have shoved Dani away if she hadn't heard the exact same thing and chosen that moment to bury my cock in her throat. Her mouth and hand flew up and down my shaft as she pumped me in and out, just carefully enough to keep from causing loud slurping noises.
I came hard on the third stroke and she held the tip of my cock in her mouth, her hand pumping on my shaft and her tongue swirling through jets of cum. I slapped a pillow over my own face to keep from grunting too loudly as I emptied myself down my sister's throat, praying to God that my father wouldn't choose that moment to unzip the tent flap.
"Kids," I heard him call. "Time to get up! We've got a lot of ground to cover!"
As the last of my cum was spent, Dani's lips left my cock and I heard her giggle quietly, felt her climb, still naked, up my body and straddle me, my twitching, incredibly sensitive cock pressing wetly against her bare pussy.
"Good morning," she whispered, her eyes shining as she smiled brightly.
"Uh huh," I managed. I wrapped her in my arms and kissed her deeply, surprising her. She gasped a little and then moaned softly into my mouth, our tongues finding each other and playing briefly. I broke the kiss reluctantly.
"We have to get up," I said. "Dad will come over here and unzip this bitch if we don't."
Dani's eyes were said as she nodded, and I couldn't help but imagine staying in bed with her all day, naked, careless and free. We dressed quickly, watching what had become our favorite parts of each other disappear with each added piece of clothing. Just as I was about to unzip the flap, Dani caught my arm and pulled me to her, kissing me deeply one more time.
"Wash your face," she whispered when she broke the kiss. "It smells like my pussy." She grinned, squeezed my arm, and motioned for me to open the tent.
Breaking camp was a relatively quick process, Dad and I working to tear down the tents while Mom and Dani gathered up the dishes and the coolers. Once the dirty work was done, we all made one last trip to the shower area to change clothes before hitting the road.
I put on a loose pair of khaki shorts and a plain white t-shirt with my summer standard flip-flops before stepping out of the shower stall. I was, as usual, the first one out, and waited for the others, leaning against the wall facing the stalls. If things went like normal, Dani would be next, followed by Dad, then finally Mom.
