Sauna Sex - Part 1

I owe an awful big favour to a guy who worked for Qantas and who happened to be staying on a crew sleepover one night at the same hotel as me in Auckland, NZ, about ten years ago. As I did most evenings, I used the gym and pool facilities, then stripped off and went into sauna which was in the male locker room. I have never been shy about being naked so I strolled into the sauna without a towel. The guy I mentioned was already in there stretched out and alone. He was slim and toned looking without being heavily muscled. I stared at his body and noticed he was looking at me too. The sauna itself was not one of the hottest in terms of temperature, which was kind of lucky, as it turned out I was going to be in there longer that the usual ten minutes.
Up until this point I had never had any kind of bisexual encounter unless you include a brief period in my teens when I used to mutually wank with a best friend on sleepovers. I had certainly never given a guy an oral. But something clicked in that quiet hotel sauna that evening and I knew I couldn't fight it.
I laid out on the wooden bench at right angles to him and we started to chat about his job, working out in gyms, the sites of Auckland and so on. As I found myself relaxing into his company I realised I had also absentmindedly started running a fingertip over the head of my cock. I wasn't sure if he was watching me or not as my eyes were closed, but somehow it didn't matter. I could feel myself getting hard, but managed to keep my voice steady as we chatted. It was only when I eventually opened my eyes and looked over at him that I discovered he was doing exactly the same. Our conversation did not miss a beat, it was almost as if neither of us had a care in the world and stroking our cocks was just the natural thing to do.
After about five minutes of this and now fully hard, he eased off the bench and sat by my legs. His fingers wrapped around my cock and took over the stroking. It felt amazing but I didn't feel awkward or embarrassed in any way. I remember a fleeting thought that we were in a lock room sauna in a large city centre hotel and although there hadn't been any other hotel guests getting changed when I came in, one could just open the door and find us. I couldn't at this point return the favour so I decided to close my eyes and enjoy the amazing sensations. Then after a few minutes of this he leaned down and took me into his mouth and sunk his lips right down my shaft. He was obviously very expert at this as I am quite big but he didn't seem to struggle or gag. In fact I remember feeling his tongue flicking very fast over the head when I was deep in his throat, and this literally made me gasp. By this stage now i knew that I couldn't fight whatever was going to happen. I was just going to "go with the flow" ......
