You're to be given exactly one tangible item that you desire. It can't be anything of the mundane world i.e. it should be something that couldn't possibly exist or defies the rules of the world as you know it. Example 1: An enormous statue of myself with a shining penis of pure gold that spans the entire known universe. Example 2: The One Ring. What is it?
Cybernetic implants that enhance my physical prowess, i.e. the stamina of a fucking race horse, the strength of a coked-out ox and the ability to have multiple full body orgasms, and the ability to cum buckets.
The Ability to shape shift to and from a purple grape flavored slime girl at will.
Said slime girl will also have shape shifting, morphing, and stretching abilities.
