While there isn't any real human nudity in this video, I think the shrieks and wails of a woman being brought to orgasm but a Johnny 5-inspired robot are NSFW, even if the action is shot tastefully in silhouette.
So, let me introduce this... After showing off some of Fuckzilla's features, the guys presenting Fuckzilla jokingly asked the audience "so, who wants to fuck a robot?" Looooong silence, followed by a "sure, why not." A young woman who called herself 'Binx' agreed to experience Fuckzilla firsthand while providing running commentary. The robot was lubed up, Binx got herself ready, and... Well... Yeah. Note that due to government regulations, we're not allowed to show Binx's face (which is why she's behind the curtain).
I bet she was a plant. If not she's my hero—it takes big balls to make your first time doing a robot a public event. (So to speak.)

My housemate Ian works at Kink and was one of the technicians who fucked the lady with the robot and modified sawzall. [Editor's Note: sawzall!] She was a genuine volunteer; Jake won ten bucks actually, betting that he would be able to find one. Later he received a completely hilarious email, containing among other gems the immortal words "Dude, you just fucked my girlfriend. With a robot."
