It was my usual walk home from football practice. A right turn at the bridge took me along the canal, where the darkening evenings and long shadows meant that you had to watch your step. I had heard people talk of it as cruising spot, and my teenage bi curiosity gave this route a little extra frisson. As I descended the steps to the canal side, my cock began to push against my football shorts, and I instinctively ran my index finger along the growing length. I could already feel the veins pumping more blood in there, and my cock head was twitching. Two minutes later, I heard some movement in the trees to my left, and I stopped dead in my tracks. There was a low moaning sound, and urgent whispers. Frozen still, I could feel my heart pounding. I moved as softly as I could towards the source of the sounds. A few yards in and I could see the cause of the moaning. There, in a little clearing, I had a clear view of a glistening cock pushing in and out of a white ass. The guy who was getting reamed was holding onto a tree, his own cock and balls swinging in time to the rhythm of his partner's thrusts. Barely suppressing his moans, his excitement was building, and he began stroking himself. "Fuck that's good. Fuck that's so good." The sound of his partner's grunts, and the slurp of the cock as it slid in and out of his ass had my head spinning. "Fuck me. God, keep fucking me like that. Fuck me. Fuck me" "Like it in there, you little bitch?" "God yes." As he turned his head towards his lover, he caught sight of me, stroking my own teenage hard on. I was terrified, and my first instinct was to turn and run, but I couldn't tear my eyes away from that cock that was so deep in his ass. He held my gaze, then smiled. He crooked his index finger to beckon me. "Don't just stand there wasting that hard cock. Get it over here in my mouth" I stumbled over, feeling light headed. Within a second, he was pulling my shorts down and licking my shaft. I looked up to see the face of his lover, who was now groaning loudly. My cock tip was licked. "Hmm...plenty of precum. Been watching a while, you dirty bastard?" I tried to reply, but I was concentrating so hard on not exploding into his mouth. I felt his beard rub against my balls, and I felt my cock head right up against the back of his throat. I was unlikely to last long. He took it out of his mouth, wiping away the saliva and gripped me hard. He looked up. "You ready to come?" "Uh-huh" "Come on my ass" he croaked. I moved to his side, my throbbing cock right on the edge of the biggest ejaculation of my life. By now, his partner was pounding his ass for all he was worth, but he as able to look at me and grin. He pointed to his fantastic wet prick as it withdrew from the hot ass. "There. Get it there. Lube me up with your cum" Sure enough, a couple of long strokes on my freshly sucked dick led to a spurt of cum all over his cockhead, and on his partner's hole. He scooped some up on his index finger and put it in his mouth, and winked at me. Then there was the sound of asshole swallowing his big heavy cock once more, and the slurping sound as he withdrew it before one last deep thrust. "Fuck, yesss" After that night, my journeys home from football practice that summer were always eventful...
