Purple Passion Rocket
take a guess, whats shaped like a rocketship, has a purple top and is full of passion.  
Cindy: "I heard that Evan over there has a huge purple passion rocket."
Evan over hears this.
Evan: "How about you find out for yourself."
(Evan whips out his dick)
All the girls stood motionless in amazement, not only for the giant cock in front of them, but for the bravery of Evan for whipping it out in the middle of math class.
