Caste Heaven
Another favorite. It's a fucked up story at the start (and at the end) but its SO GOOD. Azusa used to be the king of the classroom as decided by the caste game the school plays, but in his second year he ends up being the slave. Which is mostly just the personal sex slave to the current king of his class. Also, all the other stories and pairs in here are amazing!
