Sato isn’t just good; he’s record-breaking good, having set the bar at San Francisco’s annual Masturbate-a-thon with a staggering 9-hour and 58-minute session. His dedication includes a daily two-hour warm-up while his girlfriend goes about her routine, sometimes even timing his performances. Because, hey, champions need coaches, right?
