When a girl is going down on you, and just before you climax you pull out of her mouth and nut in your own hand. Then fling the jism in her face, as you jump to your feet, making sure to properly mimic Spidey's web slinging hand motions. Now stand in a position of bravery, and power like any superhero would. Be sure not to react when she yells at you. Stand tall and proud, not too many guys get the chance to do that these days.
Yeah so i nutted in my hand... And i was all like "PLAH SPIDERMAN!!!" And then she was all like "WHAT THE...?" And i was all like... "shhhh baby, the games back on."

A superhero belonging to Marvel Comics. Because of a bite taken from a radioactive spider, young college student Peter Parker has the ability to climb walls, to sense danger, and to shoot webs like a spider. He made a costume for a wrestling match, a burglar shot Peter's Uncle Ben, Peter went after the burglar, and killed him. Peter changed his costume to the costume we know today. And that's the origin of Spider-Man.
Who am I? I'm Spider-Man.
