Dominants, Submissives and Tournaments

Dom/sub universe. With the Triwizard Tournament coming to Hogwarts, submissives Harry Potter and Moonbeam Lupin not only have to worry about a larger number of persistent dominants, but Harry's name has come out of the Goblet and he has to compete. Will he survive? And just why are Viktor Krum and his friend staring? Rated M for paranoia. OC/OC HP/VK
