I first saw this video on PornHub a few years ago before the whole purge (but I think that it was on other sites). Anyway, it was titled simply “Korean Trainer” and it’s a solo video of this Korean guy jerking off on the floor in what I assume is a gym. The video isn’t very long and he cums pretty quickly. He is wearing these aqua/cyan/light bluish greenish shorts and is shirtless the whole video. Let me know if it sounds familiar, thanks!
