Pretty Boy Series by Ana Raine

Kai Masami always thought he wanted to go to Japan and fight for Pride, a UFC fighting branch, as a Karate fighter. That is, until he meets Liam Evans. Need for Liam leaves Kai panting madly with desire. Liam is untouchable, though. Kai will do whatever it takes to forget about Liam -- even joining a BDSM site, where he meets a man who wears an artistic fox mask and calls himself only "Master." Who is Master and will he be dominant enough to make Kai scream into submission?

Kai Masami has finally received his invitation to fight for Pride in Japan. If he wins, he will be given the opportunity to stay in Japan and become a permanent Pride fighter. But this choice would take him farther away from his lover and Master, Liam. Kai must choose which is more important -- facing his family and his past? Or staying with Liam and being able to admit his complete devotion and love...
