My automatic go to would be telekinesis. Second go to would be mind control. Third would be time manipulation- pausing, rewinding, forwarding.
But if I really had to choose something piggy, I would want the power to grant other's wishes with a twist. They would have to willingly participate in some raunchy, [banned word], cum dripping action of my choosing to be granted their wish. They would come to me with a some good party fans and their desire ... and I pick some pnp fun thing I sense that they would usually never wanna do. Could involve me, could involve a group of friends, could involve them bringing over a sibling or other family member. There are always guys in front of home depot lol. My imagination would be my limit. In the end, the price would be their cum ending up wherever or in whomever I wanted.
