When you're a Majacula (Magician Dracula), and you're looking for Zirconium, but you really have to bang one out, so you jerk off but then immediately make your cum disappear as it exits your 'wand'. Fapacadabra!
Damn, it's been a long time since I've been sawed in half, if you know what I mean, but I don't want anyone to know I was playing with my cup and balls in here. Guess I'm gonna have to majaculate!
