Spa encounter

I won a free massage at a high end spa and didn't know what to expect. I arrived and checked in. I was impressed with how fancy it was and the amenities. I was introduced to my masseuse and got my massage. The real story isn't the massage but what happened after. I was allowed to use the rest of the amenities like the steam room, cold plunge, pool etc. The place had a few men, all of them older than me. So I went into the steam room and was alone in there. When I was done, I went over to the lockers and undressed. As I undressed though, there was an older man on the scale weighing himself. I couldn't help it but I was looking at him and focussed in on his cock. He had a huge hanging cock so I was mesmerized. I must have been obvious staring when I realized it was quiet and I could feel him looking back at me. I glanced up embarassed and he had a smile. He was smile at me and then pulled on his cock like saying, yes I have a big cock. I sort of smiled back and he stayed there looking at me with a grin. So I couldn't help but make a move. so I got up and started walking over to the showers. As I got up, I let my towel slip off showing my smooth shaved parts. As I walked by him he stared me down like a hungry wolf staring at his prey. As I passed him, I continued to look at him and glanced at his cock which at this point it was very clear what was happening. My heart was beating really fast and I couldn't believe what I was doing. But as I walked by and passed him, I also caressed and squeezed my round ass in a sexual way. I glanced back and he was looking at me, specifically my ass, and smiling. I walked into one of the shower stalls which were quite large and turned on the water. As the water heated up, I waited in the shower wondering if he was going to take the chance and come to the shower. To my suprise he did. He walked up and stood there at the door. The glass door was frosted and steamed up but I could see he was there facing the door standing there, probably wondering next move. So I opened the door with a smile and he walked in with a smile. As he walked in, he said hi and we both closed the gap between us. As he got close to me, I reached out and grabbed a hold of his cock with one hand and balls with the other. I pulled lightly and rolled his balls, and pulled and stroked his cock. He smiled some more whispering, "do you like it"? I nodded yes and at that point he reached around and grabbed my ass, squeezing it with a firm grip. He was an older guy so I wasn't even thinking he would get hard, but he did. His cock started swelling quickly as I stroked it. He looked at me and motioned down like saying why don't you suck my cock. So I kneeled in front of him and popped his cock in my mouth. After getting hard, his cock was giant. I don't know how I was able to get it in my mouth but somehow I did. He pushed and pulled my head in on his cock more and more as he enjoyed me sucking his cock. I could imagine he hadn't had something like that in a long time. he was really enjoying it and breathing really heavy. I started to realize his cock was starting to throb and it was hard, very hard. He whispered quietly to me and said I am going to cum. It wasn't long, a few or several seconds later and he started shooting. It was so much I finished him off stroking him with my mouth open letting him cum in my mouth. He had such a big smile as he came. When he finished, I spit it out and rinsed my mouth. He was very appreciative and wanted to lather me up and clean my body. So I let him. He wanted to soap me and play with my ass and that he did. When he was done, we rinsed off and got out of the shower. As we sat there on the bench, he told me he had enjoyed that a lot and wanted to know if I'd be interested in going over to his house regularly. I told his yes and we exchanged numbers. Once we were dressed and we were leaving, he
