It was late afternoon when we pulled off Utah 63 into the campground. Dad wound around the narrow paved roads, looking for the site we had reserved, finally finding it at the end of a little drive off a parking area. It was a tight fit for the truck and part of me wondered if we were even supposed to drive back to the site, but dad didn't seem to care. He wasn't interested in carrying all our gear the almost hundred yards from the parking area to the site.
According to the map we had of the park campground, the bathrooms were nearly three hundred yards away if we cut across the open areas, a lot farther if we followed the roads. While that wouldn't really affect me, considering the number of trees in the area, it could be a bit harder for the girls. For the desert I was surprised how many trees there were, not only little low scrubby ones, but also tall and full enough ones to create a considerable amount of shade.
It was well over an hour before we had camp set. Jenny and I decided that since there was plenty of room in the site we should put a little separation between our tent and my parents. We elected to put our tent on the far side of the fire ring from where they set theirs, giving us about fifty feet more separation than the night before. Not that it'd help all that much as noisy as my mother was, but hey, any little bit helps.
With camp set, mom and dad set about cooking dinner while Jenny and I explored around the area a little.
"God I'm so fucking horny," Jenny said quietly as we walked along the twisting road between the sparsely populated campsites.
"Yeah? How come?" I asked.
Jenny turned to face me and stopped walking. She pulled her shirt up over the tops of her bare tits and then pushed her shorts down to expose her bare pussy. "Cuz someone wanted me to walk around without any underwear on!" she said with a grin. "If I could get away with walking around shirtless like you are, you'd probably love it!" I stepped closer and reached out to cup one of her tits and stroked my fingers across her hard nipples.
"Of course I'd love it. But you sure it wasn't me slipping my fingers into your pussy in the truck on the way here that's got you so turned on?"
"God, you were so fucking bad! I wanted to do so much more than tease your cock through your shorts. If you hadn't made me climax when you did, I think I'd have stripped and fucked you right there in the truck."
"Glad you enjoyed it," I answered with a smile.
"Yeah. But after a climax I like to be fucked. So you made me climax, what are you going to do about the fucking part?"
I looked around and then took her hand, pulling her off the road into a vacant camp site. I walked to one of the picnic tables, her shorts still around her thighs, and then turned her between me and the end of the table. I pushed her back, coaxing her to sit on the edge of the table and as she lifted her legs I pulled her shorts down and off, leaving her nude below where her shirt was pulled over her tits. "How about this?" I asked as I pushed my own shorts down, freeing my cock, which had been rock hard for hours.
I teased my engorged head up and down her slit several times before slowly feeding it into her, my fat head stretching her and brining a soft moan of pleasure to her lips. "I think this is exactly what you should be doing," she moaned as I pressed deeper into her, her pussy slowly accepting my fat shaft.
"Ohhh god," I groaned as I started stroking in and out of her already sopping wet pussy, her juices lubricating me and allowing my strokes into her to be even deeper. She lifted her arms and pulled her top off, leaving her naked except for her little white canvas tennis shoes and anklet socks as she sat on the end of the table taking my cock in her.
"God damn you feel good in me," she moaned softly as I plunged into her over and over, my thighs banging against her bare ass. She lifted her legs even higher and leaned back, resting on her elbows, her tits bouncing and swinging wildly on her chest from the impact of my strokes. "That's it brother. Fuck me. Fuck my hot little cunt!"
"Oh damn," I groaned, plunging into her harder.
"You like that? You like it when I talk dirty?" she asked breathlessly. "You like it when I beg you to fuck my hot cunt and pound your fat dick into me?"
"Uh huh," I grunted as my climax neared, the warmth and tingle spreading moments before the irresistible urge to pound a little harder and deeper into her.
"Oh fuck! I think I'm gonna come. Fuck me brother. Fuck your sister's hot little cunt!" she moaned as her legs began to shudder where they rested against my arms, my hands squeezing her hips slightly tighter as my own body demanded that I pound her a little harder.
"FUCK!" I grunted loudly as my body spasmed and jammed my cock into her so hard her ass slid on the table a little bit. A massive gush of pent up cum lanced out from my head deep in her pussy, making her cry out in pleasure, her own climax, just starting a moment before mine, being pushed to incredible heights. I stood in front of her as she lay back on the table, moving her legs to rest on my shoulders as my body spasmed and jerked, pumping more cum into her with each spasm. I could feel her pussy clamping and spasming around my shaft as she too climaxed, moans and gasps coming from her as she lay in front of me.
I lost track of how long I stood there, not pulling out until my cock had completely softened inside her. I stepped back, uncorking a small flood of our combined cum from her pussy as she lay naked on the table, her feet still resting on my shoulders. "Damn! I can't believe that the best sex I've ever had was living in the room next to me the whole time," she giggled. "I should have started fucking you years ago!"
"Yeah," I panted, still trying to catch my breath. "If only it was normal for brothers and sisters to fuck instead of being a bit on the weird side."
"I wonder how many do and just don't say anything?" she asked quietly from where she lay. "Play with my pussy a little more. Just with your fingers."
I stepped the half step back to her, my now deflated cock nearly touching her leaking pussy. I wrapped an arm around her left leg and gently stroked my fingers around her pussy, not teasing any particular part, but just gently stroking it like she had been doing to herself. "Like that?"
"Ohhhhhh perrrrrrfet," she cooed softly. I used my free hand to move up to her right breast, gently stroking my fingers around the creamy soft skin and still hard nipple as well. "Mmmmmmm. How did you know to do that?"
"Dunno. Just thought it might feel nice," I said with a shrug.
"Well, it does," she answered with a soft sigh. "Feels very tender and caring to have you doing that."
I stood there enjoying both looking at her and touching her sexy body, her fingers reaching out and gently stroking the tips along my stomach and around my pubic hair as much as she could reach, my bare body as exposed as hers with the exception of my shorts still being around my ankles. Our tender moment ended abruptly with the sound of a car, the first we'd heard since we started our little impromptu fuck fest. Jenny scrambled to pull her shirt on, having it only half way on, her shorts still on the ground at my feet while I had my shorts pulled up but my cock and balls still hanging out in the open. The car pulled up to the entrance to the site we were in and stopped. When the window rolled down I saw a familiar face.
"Fuck we've been at the wrong campground all along. This one comes with built in studs!" Trish from the last campground said out the window before opening the door.
"Oh god," I groaned softly to myself as she climbed out and walked toward me, my sister trying to cover her tits with the half on shirt. "This is Trish," I said, turning my head to my sister as I tucked my cock into my shorts. "I told you about her. Cell phone girl?"
