Lying out on a nice sunny day makes you want to strip down and feel the warm rays against your skin, and even heats up your nuts and big thick cock. If you're Hiroya at least. He's on an urban rooftop in Tokyo, and the more he thinks about the crowds of people below and the windows all around where anyone can watch him stroke, the more horny and daring he gets. Finally naked and splattering his seed around the searing rooftop, his natural exhibitionism gets as much of a charge and release as the big load bubbling up from his tightly packed nuts.
