Save his life and thanks him with sex outdoor

I was enjoying a beautiful sunny day, I was lying on my life jacket when I fell suddenly, I can’t swim much, and then I was drowning. But a young man realized and helped me, he saved my life. When we were already on the shores of the lake, I wanted to thank him. The young man was not ugly, so I made him a blowjob, I think it was the most sincere to show my gratitude. The boy excited very much for my blowjob and started to caress me the tits. My original idea was not to fuck, but since he was willing to do that, I would not have lost my chance. I’ve ridden and we had sex in the open air.
