Tasim's Tale Series by Stephanie Vaughan

Captured by the Kundari, a neighboring kingdom, Tasim is a stranger in a strange land. When he is made part of the entertainment at a lusty reward ceremony for the king's soldiers, Tasim has one hope for survival: make Dorian, the rugged captain of the regiment, his protector. A single encounter will shock them both -- but first they must survive the night.

The king's reward for a year's hard work. A little something for himself – that was all Tasim was supposed to be. When the king distributed his largess, Dorian thought only to gain a bedmate to help ease the boredom of long winter nights. But Tasim quickly became so much more, disturbing the delicate balance between an unstable monarch and his favorite. Dorian must now walk the razor's edge between his king's pleasure and his heart's desire.
