Think you have what it takes to become a masturbating champion? Can you endure longer than 8 hours and 40 minutes? Because that is what it will take to beat the new record set by both Norihiro Taneichi and Masanobu Sato of Tokyo at this year’s Masturbate-a-Thon in San Francisco. The two finalists went “head-to-head” in a competition that finally ended when an exhausted Taneichi gave up, allowing Sato to claim the prestigious title. What was their secret? They were both using the Tenga New Adult Concept line of onanism cups. WARNING!: NSFW gallery after the break.
