Unending Penis Barrage

You curse another creature to be constantly bombarded with Penis's. The target is hit with a Penis from a random direction every 6 seconds, taking 1 point of damage. The Penis always come from the direction the target least expects, and cannot be stopped by any means short of a wish spell or godly intervention. The Barrage lasts either until the death of the target or whenever the caster decides to end it, which can be done at any moment of their choice.
