I had thought I was het, had a few girlfriends, but sex was ok nothing more.Then, one Sunday afternoon, up in Glasgow, I needed a pee and went to a bog I often visited.I entered the cubicle, and as I sat down I noticed a mag scrunched up lying on the floor. I could see flesh but only when I picked it up did I realise it was a gay mag. And a hardcore one at that. I hadn't seen one before and my eyes popped out. Here were naked guys, buff-bodied, fucking and sucking to their hearts' content.I picked out a pic of two young guys sucking each other off. It was a series of photos and the last photos were of their faces full of cum. My God, I thought, that is what I want. I quickly pulled my pants down and started wanking away. My knob was soon wet and precum leaked from it. I then realised that there was a small hole in the wall of the cubicle, so small that I had never seen it before. I bent forward, looked through it. My God, I could see the urinals and , to my surprise, then a guy came up to them. he unzipped and pulled his knob out. It looked fat and he started looking over at my cubicle.I put the mag down, as he turned half towards me. I could see he had shaved his pubes, and he was wanking his cock slowly.Then he undid his belt a bit, and I could see more of his pubes. I looked at his face, and he was stood there, his tongue out, looking intently where the hole was. There was a space at the bottom of the door, and I had been wanking away not realising he could see my ankles, with my pants round them. His cock was lovely, so much so that involuntarily I leaked some spunk and it fell to the black shiny floor. He gasped when he saw it. "Fucking hot!", he gasped. By then I was so worked up I opened the door and showed him my stiff dick, waving it at him. He was in his 40s or so, clean-shaven and he whispered to me "Come over!" I was worried in case someone came in but I obeyed. "Right," he said, "suck this!" as he waved his dick at me. I gulped.It was dangerous, sure but my heart was beating, I wanted his dick. I bent forwards and licked the tip. It was wet and tasted like sausage, strong and salty. He grabbed my head and pulled me towards him. i nearly choked on his fat cock, but the look in his eyes... pure lust. I was wanking as I sucked him and in less than a minute I came over my boots."Yes!", he whispered, as he saw this. I could feel him buck as he fucked my mouth, his foreskin sliding back and forth in my mouth. He pushed me roughly as he came and his spunk filled my mouth, some dribbling down my chin and onto my shirt. "Fuck fuck fuck", he moaned as he came.He took his dick out of my mouth quickly but I seized it slid it back in. I licked the cum off it before he zipped up, and hastily left. I licked my lips, tasting him on them. I knew it now, I was gay, I wanted cock, as much as I could...
