Looking for story similar to the verlon

[Guest Rei]

I'm hoping someone can help me find this story. It is similar to the verlon and deals with punishment. A boy is found after being in the system for a while. He is taken to his home planet and is claimed to be a sub by a doctor. The dominant can punish the sub and he has a brother who abuses his sub. It is later found out that the doctor gave him something that turned him into a sub. I think there was aliens and people who could turn into cats or dogs.

There is a side story to this dealing with a man who owns a ship and is running away from his mate; who is an alpha. The owner of the ship sleeps with a crew member while running away.

If anyone can point me in the right direction I would appreciate it. Thanks.

That's Erosa and its side story. I think they've been removed by the author.
