This book can be downloaded and read in Apple Books on your Mac or iOS device.
Weretiger Terry is used to being in charge. He's the boss, even when that job is as stressful as can be. So when he hears a new BDSM club is opening in Dallas, he has to go find himself a twink to help relieve his stress.
What Terry finds is werebear Ash, who's the bigger apex predator in this situation. Ash is happy to turn Terry's expectations upside down and teach Terry how to accept what he needs. Even if what he needs scares Terry half to death.
