I decided that I wanted a couple of days off work, and so I packed up the car and headed along the coast to check out the beautiful coastline of Victoria. I always like to stay in on-site cabins at caravan parks as you tend to meet people there and it's a hell of a lot cheaper than motels. I got to one of the coastal towns, got a cabin and spent the day sight-seeing, had dinner at the local pub and went back to my cabin later that night. The cabin did not have a shower and I had to use the males showers so taking the key, I went to the shower/toilet block. I was staying here on a Tuesday night, so the caravan park was not busy, (and the cabins were 40% cheaper.) The showers were not separate showers, they consisted of 4 showers, so they was no privacy. Not giving it another thought, I stripped off and began to shower under the second shower head. I was a bit horny and mydick was not completely hard, but it was also not totally flaccid. I was facing the shower wall when I heard the door open and I turned around to see a guy about 35 or so. He was wearing shorts, thongs and had a towel wrapped over his shoulder. I also noticed he had black chest hair, and was carrying a small toilet bag that must have had his toiletries in it. I smiled and said hello to him and he asked me how were the showers. I told him it took a while to get the hot water going but once it fires up, it is good. While he was talking to me, I could not help notice that he had a quick look at my cock, which was embarrassingly getting hard. I turned back to the wall, and thought how fucking embarrassing this must be. He took the shower right next to me and this was when I first his cock. It was about 8 inches long, cut and like mine it was also hard. He began to lather himself up with his soap, facing the wall and talking small talk, nothing much really. At first, I thought this was just a guy with a morning boner but he began to tell me how his wife had sucked him last night. He described her tits, her pussy, and how she took his cock, saying that he would love to see me do her, but she won't be part of threesome. I joined the conversation asking him to tell me more about her, and we then faced each other. We grabbed our own cocks, as we began to wank off, stroking and using his wife as our motivation. We knew we didn't have much time, at any moment, another guy could walk through the door and he would have clearly seen two guys wanking, so he told me about his wife riding his cock and her tiny tits bouncing up and down as she rode him like a dog. It was only a short period of time, but before long we both blew our loads, shooting off huge streams of thick juicy cum all over the wet shower floor. Once we had blown, we finished showering, got dressed and walked out. As we walked out, I told this guy I was in cabin 5 on my own and will be here for another 2 days. He smiled as he walked away.
