He turned his head and looked at me, "What's that?"
I turned onto my side and rested my head on my hand. My elbow on the rock so my head was elevated, "Conventional wisdom says that the quickest way to ruin a friendship between a man and a woman is to introduce sex into the equation. Our friendship has already been taken away. What's to stop us from getting naked and fucking on this rock right now? I'm going away to school; you're going to the goddamn jungle. Our window of opportunity is short, so what's stopping us?" I put my hand on his chest, let my thumb play with his nipple a little bit before I slid my hand down below his waist and rested it there. I could feel his dick grow beneath my touch and in no time it was straining to get out of his jeans.
"Are you sure you want to do this?" he asked.
In reply I simply sat up and straddled his waist. I unbuttoned my shirt and took it off, along with my bra. I laid them next to us on the rock and took both his hands, placing them on my breasts. He squeezed and kneaded them and raised his hips. I could feel his cock pressing against my pussy. I leaned over him and dangled my tits in his face. When he took my nipple in his mouth and began sucking I knew that there was no going back now. I tried to keep my boobs accessible to him and I reached behind me and struggled to undo the button on his jeans. I couldn't get it so he reached down and helped. He unbuttoned, unzipped, and slid his pants down. His cock popped free and I could hold it. Then he reached between us and unbuttoned my pants too.
Reluctantly, I raised up and he let my tits go. I stood and pushed my pants down then I sat and removed my shoes and pulled my pants all the way off. I moved back over next to him and he put his finger in my pussy and began clumsily moving it in and out. Finally, I had to reach down and take his hand. I showed him what I liked and he got better at it. I took his dick in my hand and we stroked each other until he came. Jimmy wasn't a spurter, the cum oozed from his cock and slid down his shaft to cover my fingers. It felt warm, I felt warm. There was not a lot of pressure behind his ejaculation but there was a lot of jizz. I thought it would never stop and I just kept stroking. The flow finally stopped but his dick remained hard.
I hadn't cum yet but I was wet so I lay over on my back and pulled him on top of me. I helped guide his dick inside. The feeling was beautiful. He filled me and we became one. One person, one being, then he began to move; he thrust himself in and out of me. I held his ass and pushed to help him on the downward stroke. He didn't need my help but I liked doing it and I kept doing it until the pleasure overcame me. Then I wrapped my legs around his ass and bounced up and down off the rock on his cock. In my unconscious reverie I bit his shoulder. I drew blood, not a lot but enough that I was embarrassed about what I had done when I recovered my senses.
Poor Jimmy, I had him immobilized, my legs wrapped around his ass, my arms around his neck, my pussy squeezing his cock and my teeth embedded into his shoulder. I let him go. "Did you cum again?" I asked him. "Did you cum inside me?" He shook his head. I pushed him over on his back and crawled down between his legs to take his cock in my mouth. It was my turn to be clumsy. I had never given anyone a blow job before but he put his hands on the sides of my head and showed me what he liked. We developed a rhythm and once we had that; it didn't take long. He came a second time. I tasted his seed and savored the salty, sweet flavor before I swallowed it down.
I crawled back up and put my head on his shoulder. I licked away the blood that was there. We lay in silence, naked on the rock, in the sunshine, until the shadows began to get long.
"I guess we showed them," he said.
I laughed, "Yeah, I guess we did." I paused, "Jimmy..." he shushed me.
"I'll try to take leave around the holidays." He said, "We can spend time together that way."
I nodded and sat up I pulled my bra and shirt back on before I leaned over and kissed the head of his dick. I finished getting dressed and picked up my fishing pole. "I'll see you at Christmas then?" I asked.
He nodded and I began walking back up the hill - away from the river, away from the rock, away from Jimmy.
My mom took me to move into my dorm room two days later and Jimmy went away to basic training. He was too gentle a soul for war. Jimmy didn't last six weeks in Vietnam. I got the news from my mother on a phone call. He never made it home for Christmas.
