We are camping out in Arizona, its been hot all day and we completed a 5 mile hike in almost straight up pathways. We take a dip in the nearby lake, leave our clothes off and walk back to the camp site. The fire is going, mostly to keep animals out of the camp, it is dark and he offers to give me a back rub, knowing my muscles are aching. It starts out very relaxing, and I almost drift off with eyes closed, I don't notice he has slipped his belt around my neck until it is tightening down on my throat! I struggle as he pulls on the belt, cinching it, my hands clawing at the damn leather cutting off my air. He slams his dick into me and is really pounding me. Now he pulls me up from lying on the ground with the belt, as I struggle he bends me over a nearby rock. His hot breath on my neck as I twist and turn, his rampaging tool driving me crazy in my ass. I grab a quick breath, inflating my lungs as he loosens it for just a moment... on purpose. Now his mouth is on my neck, chewing, then biting, blood starts to flow down my upper chest, he has bit into my jugular vein! As he continues to pump into me my own dick is scraping against the rock and I know I am going to cum. I'm probably dying which makes it even more erotic. As I cum, he pulls the belt tight again, forcing my head up and as I struggle to breath I see the flash of silver come past my head. In an instant my left pec catches fire from the knife he has plunged into it. I cum again as he does in my ass, and slump to the ground.
