I matched her momentum as best I could, fucking her back. It must’ve looked incredible from Melanie’s perspective -- to actually see my cock slidi...g in and out of her sister’s warm, wet pussy. To watch her sister’s ass cheeks bounce up and down with Brittany’s little brown asshole peeking out from in between them. She could see my balls bouncing with each thrust. Honestly I don’t know how she kept herself from masturbating to this. “I can’t last too much longer,” I said in a hushed tone to. He asked me do I suck old cock, I said yes. He then asked me will I suck his dirty old sweaty dick, I said yes. He said that he knows that I like unwashed old cock and that he never washes his, he said that he has a huge cock for my ass. I asked him how old is he and he said that he's 74, I told him that I'm 23. The grandpa smelled like sweat, rotten cheese, and onions. I told him to follow me to my room, he held his hand on my ass as he followed me to my room. He told me that his dick is. Suddenly I heard a "god dammit" and then a thud over on the trail . I stood up and could see a fellow backpacker laying on the trial, like a turtle on his back. I could see he was ok as I walked up to him. "are ya OK" I inquired. "Yes thats the second time I've tripped today and busted my ass" he said "Well maybe its a sign you need to stop for the night, come on over and join me here if ya like" He nodded his head and scrambled to his feet and came over to my fire and dropped his pack. " I can. ? Laughing you says, ?I think you are finally ready to take my cock and cum all over it.? With that you thrusts deep into me filling me with your strap-on cock. Stretching me making me moan in pleasure. As I push back towards you I can feel my long denied orgasm building. You fuck me deep and hard sending me over the edge. With a loud cry of pleasure my orgasm finally breaks free and I cum long and hard. As my orgasm is still coursing through my body you pull out of me. Coming around the desk.
