Sold to the Enemy by Sara Fields
Captured by the enemy, Aubrie Kent is stripped bare and put on shameful display to be sold at auction, but worst of all, the alien who buys her is the ruler of the planet she failed to conquer.
Commander Edagon has plans for the little human girl who dared to attack his world. He's going to punish her in ways that leave her cheeks blushing and her bottom sore inside and out, but that will only be the beginning. He's going to use her beautiful body in every way it can be used. First she will beg for mercy, but before he is done with her she will beg for more.
