Sneaker lad persuaded to let me use his feet and cum on them

I've finally persuaded my friend, who really likes sneakers, to let me use his feet. That time, he was wearing white Nike shoes and very nice black ankle socks. I begin as usual - with his white AirMax 270. After a few minutes of pleasure, I moved forward and took off his shoes, so I could also play with his socks. In the end, I also took one sock off, so I could cum on his bare foot. In the meantime, I was slowly stripping him off his pants and boxer shorts - the touch of cock and balls gives me additional pleasure. And, he likes it too - his cock got quite hard then.
