Survivalists

I watched Tina’s face as we screwed. Her features softened, became more sensual as the activity between her legs sent shivers of pleasure through her. She closed her eyes, lifted her head toward the roof as whispers of sound escaped her lips. Each time she stroked my cock with her pussy she uttered “uh!”

I was still for a while, letting Tina take what she wanted the way she wanted but I couldn’t hold back the need to fuck her too. I started flexing my ass, meeting her movement with my own, careful to keep from pulling out of her. She dropped her eyes to mine and pulled me into her stare as our bodies meshed and bonded. I put my hands on her hips and began to lift her then pull her down on me with more energy. I felt the slit I was deep into getting hotter, slicker and softer as we gained more confidence in what we were doing. I could hear the slip-squish of my cock sliding through the opening of her sex.

I lifted Tina up until my erection was standing free, alone, then pulled her hard back down on me. As her butt crunched my balls her eyes flew wide and she gasped “Oh!” Watching and hearing her reaction pumped me up even more so I did it again. Tina’s eyes went out of focus and she started to convulse. She bent at the waist, butting her head against my shoulder and groaned in my ear “Uhh! Uhhhhhh!” She was shaking while slamming her cunt on my cock. I went over the top and started spewing a second load into her.

She was completely spent, lying on my body, her chest heaving as she sucked in cooling air. After a moment of silence she lifted her head and looked at me. “I never in my life expected to feel something like that with you. Maybe mom and dad are smarter than we think.” We went to sleep with her lying at my side, her body pressed against mine while I held her close with an arm.

The sky was pale blue when she woke me with kiss on the cheek and her nose pressed against my neck. “Hey Von, we have to get up, I hear them outside.” Not only was she nuzzling my neck, she had captured my morning erection in her hand and was stroking it lightly. I tried to push her to her back but she spurned me by saying “Not now, we can’t stay in here that long, but think about me.” I got my first full look at my sister’s nudity when she got out of the bed to get dressed, my erection thumped with aching lust as I watched her legs and ass.

Mom and dad had to have seen the change in dynamics between me and Tina. She and I flirted like high school sweethearts as we worked through the day. There were whispered promises, stolen pinches and caresses. By the time the sun went behind the mountains I was ready to fuck my sister all night. I was a little surprised at how fast I stopped being timid. I stripped naked in front of her and willed her to look at my long thick erection. She peeled to bare skin then stood in front of me, lifted her arms wide then turned in a circle, showing me what I was about to take to bed. It was too cold to play in the open air so we sprinted for the bed and clung to each other to warm up while giggling and bouncing under the quilt.

I tried to get over her, to stick my rock solid shaft into her but she held me at bay, smiling, “Not yet, we have lots of time.” Tina made me slow down; she made me appreciate having her near. She told me how to touch her and play with her body while exploring mine. After a few minutes paying attention to her breasts Tina pushed me to my back, leaned over my face then kissed me for the first time. I wasn’t a complete stranger to girls; I had made out often and hard with Lena so in seconds my sister and I were lip locked to each other while our internal fires built even higher. The next time I pushed her over she didn’t protest, she opened up for me and I slipped my cock into the tender hot environment she was offering.

Tina and I fucked three times that night, each time we learned more and more about how to pleasure and enjoy the other. Two months later our stay at the survival home was over and we were well experienced. When we got back to the city the first thing I did was call Lena. I had learned a few things and was confident I could seduce her, Tina went back to Marty. Mom and dad never said anything to us but I could tell they were satisfied that their children had taken the final steps to adulthood and learned even more about surviving the coming holocaust.
