So it isn't a long story but it is something. This happened about six years ago when I went away for the weekend to Spain on a business trip. I went with a few mates from work and we all decided to book a cheap hotel and share a room between four of us.
After the first day of meetings I was ready for a break. I went to the spa, went in the pool and then decided to go in the sauna. Which I usually don't do because I find them a bit clostrophobic, but when I went in there was me and this other bloke in, both naked and didn't think anything of it. After around 10 minutes the other man got up and went out. I was left on my own and suddenly got very aroused. I thought I would have a quick jack off, which I did.
Then suddenly the door swung open and a beautiful woman came in and sat about a metre away. She pulled her pants down and sat there naked. This made me want to cum there and then but I didn't and just tugged it, trying to be as discrete as possible. After around 15 minutes, she got up and poured some more water on the stove and the room filled with steam. She sat back down a little closer to me. As I was sat there I felt a hand on my thigh, and it was the woman. She started rubbing my thigh and whispered, 'enjoy!'. before I had time to respond my cock was up looking straight at me and I was getting a very nice hand job from some one I had never met.
Being the gentleman I am I started rubbing her thigh and made my way to her pussy. I started rubbing and her breathing got heavier. I got more adventuress and started really fingering her wet pussy and then she started squirting and couldn't stop. It was like she was weeing, but I know she had ejaculated. This sent me over the edge and I cummed. She grabbed a towel and said thanks and I said anytime. She wiped down and walked out. I tried to follow but she went straight to the womens changing room and I didn't see her again, until the next day when I saw her at the breakfast bar, she smiled and I winked, that was the best business trip ever
