write me a steamy fanfic about a pair of very forward and aggressive female goblins who femdom a pale male elf, who secretly wants to submit to them. though he tries not to show it he himself makes things escalate. get to the physical action fast, describe it very vividly, and make very clear what is going inside of what. the goblins should drink everything the elf makes and they should constantly want more from him. the goblins want to have the elf inside of them, and also for the elf to shoot loads inside of them over and over. make sure this happens, and describe just how huge the loads are and how they gush everywhere. the fanfic should start with the action already underway, the reader will infer what has happened before.
