His Husband the Werewolf - A Kinky Collection, #35

Connor has been married to a werewolf long enough that surely he should be able to keep track of moon cycles and be prepared. But once again the full moon has caught him off guard, and he comes home to find himself utterly-and delightedly-at his werewolf husband's brutal mercy.[This book depicts knotting, pain kink, and wildly unrealistic sexual situations.]
