You're Watkins, you have a cumbag.
You found it in the street one day, full of dried cum and random objects. You washed some of the cum crusts out of it and found glued with old cum an instruction manual inside. It says that every time you cum in your bag someone nearby dies.
You can choose who dies if you write the name of the person in toilet paper and place it inside your cumbag before you cum in it. Used in this manner, the cumbag has no range limit and you need only know the name and face of your victim.
You tried cumming in it while you were in school because you're a horny guy and your gym teacher had a heart attack and died. This thing is the real deal!
How will you use your wondrous powers?
> You will cum in your bag everyday, you don't care who dies
> You will write the names of criminals, you will be the cumgod of the new world
> You will hide your cumbag and never use it
