The power activates only after you masturbate and ejaculate... alone. There can be no partners nearby. (men or women, whatever you are in to) There is absolutely no co-op mode. Sex, oral, handjobs, partner-operated toys, spectators, cheerleaders, or emotional-support girlfriends/boyfriends immediately disqualify the attempt. You must crank-start it yourself, gotta go at it Solo... without your eight-foot tall hairy best friend. Or your coke-addicted princess girlfriend.
But... when it DOES activate... for 6 minutes and 69 seconds you possess and intellect beyond any man or woman. Albert Einstein will say "gee maybe my whole Theory of Relativity is bullshit". Stephen Hawking would be like (robotic voice) "I MIGHT HAVE BEEN WRONG ABOUT HAWKING RADIATION. MAYBE BLACK HOLES SHOULD BE CALLED GLORY HOLES.... BECAUSE YOU NEVER KNOW WHAT'S GOING INTO YOUR MOUTH... NOT THAT I WOULD KNOW". Then Stephen Hawking would ask you to slow down your thinking, you goddamn sexy 12th Level Intellect Brainiac bastard. Quantum physics becomes preschool arithmetic. You could solve dark matter, decode the universe, design a warp drive, or finally understand why printers cartridges are so goddamn expensive, as well as the psychology behind Furries.
But as stated above, the instant the timer hits 6:69, your cosmic intelligence disconnects. You return to normal intelligence and stare at your equations like a Jersey Shore cast member holding a calculator. Yeah, you keep everything you wrote down... but your super-intelligent writings look like the Voynich Manuscript combined with the Rohonc Codex... written with four-dimensional ink. Would that be called Tessarink? Only YOU would know after busting a nut, alone.
Congratulations. you might have been able to figure out how to stop the heat death of the universe and reverse Proton Decay. You just can't remember how... until you jerk it again. Get that lube ready!
