Chapter 12: Avoiding Detection

I was awakened from sleep by the sound of my father’s voice, “Oh, let them sleep in a bit more. It’s not like we need to rush home; we can take our time packing up this morning.” My heart started pounding, and I opened my eyes. Tanya’s eyes were already open; I was staring straight into them. She was clearly as alarmed as I was. Then I realized I had morning wood, and it was delightfully positioned between my sister’s thighs. Heedless of the danger of discovery, I used my hand to try to guide my hard cock back into Tanya’s pussy. Forehead to forehead, Tanya whispered, “Again? Are you insane?” As I experienced the pleasure of finding my sister’s pussy lips with the tip of my dick, I rubbed gently, hoping to get Tanya as worked up as I was. I felt her plump lips opening to my cock, and I could feel the wetness of her cunt again.

“You are insane, but I guess I am too!” Tanya sighed quietly as she stopped resisting my cock. I entered her body, this time with our parents awake and moving around the campsite. Tanya kissed me fiercely to stifle the contented sigh we both tended to make when I entered her. Before I could try to start fucking my sister again, one of our parents said something, and Tanya’s body stiffened nervously. It wasn’t just her arms and legs, either. The muscles inside her core stiffened too, and with my cock in her pussy I felt a strange sensation that was almost painful as Tanya’s cunt contracted around my cock. Then it was my turn to stiffen, as I decided that having her body squeeze my cock like that felt amazingly good. Tanya must have realized I liked what had just happened, because after the intense squeezing let up, her pussy tentatively clamped down on my cock again. I wasn’t fucking my sister at all, but her pussy was so active, it felt like I was pounding the shit out of her. As Tanya worked out how to squeeze my cock with her vagina, I held her ever more tightly in my arms, and our lip lock never broke. It was a good thing because whatever Tanya was doing, it suddenly felt like her pussy was actually trying to milk my cock. I’d have yelled out for sure if our mouths hadn’t been squashed together. Fuck, did what Tanya was doing to me ever feel good. I could feel the need to spew cum into my sister’s belly rising uncontrollably. I started to feel light headed as her pussy squeezed and released my cock again and again. One particularly tight squeeze pushed me over the edge, but as my cock throbbed, there was no way for my cum to flow out of it. When Tanya stopped squeezing me so tightly, the orgasmic pulses, which would normally pump cum out of my cock, had already ended, but I was still full of jizz. I had never experienced anything like this before. I felt like I had just cum with maybe the most powerful orgasm Tanya’s pussy had ever given me. However, I didn’t feel any of the relief that usually follows right after a good cum. If it had been insane to try to start fucking Tanya to get rid of my morning wood, it was ten times crazier wanting to fuck her again. Having a wad I knew I should have shot still inside me was making me reckless. I broke the kiss to whimper, “More, but don’t squeeze so hard.”
