I blow him for a long time outdoor

We inflated a inflatable mattress and I climb with my knees on the pillow and with my mouth deep in his cock. He fingers my pussy and ass while I suck his thick cock and then he asks me to ride his cock. I love when he lets me ride his thick cock and feel it rubbing me deep inside. I have a lot of orgasms when I fuck with him and you can see it. Also, we are fucking next to a railroad track, and from time to time trains pass by.
