Master Me — H.C. Brown

After Leo Marshall survives a storm at sea, he discovers the watery vortex he hurled through was a gateway to another realm. As a filthy disease ridden human, he is not welcomed into the strange world of unusual diverse humanoids and finds refuge with a shifter. His immediate lustful attraction to the delicious BDSM Master, Ashrin of Ecatnie Pride is so powerful it's frightening. The rules are different in this future realm and frequent sex with a multitude of partners is expected. Leo wants Ashrin exclusively but is afraid his Master will love him -- to death.
