Can we just let the miserable dude die already? he clearly doesn't wants to live a long life, the witches are clearly in need of money, and we the readers (Me, my self, and I) don't care about him.
It is a happy ending if he just commits assisted suicide by diamond ejaculation.
Instead now he got tied and is being in a cycle of neglect play in which he will be stimulated but wont really cum from it.
