Love Song of the Dominatrix (Nexus)

Dinah is a tough-talking bisexual dominatrix with a weakness for redheads. When she meets Grace, a beautiful hotel receptionist looking for excitement, she can't resist converting her to a life of lesbian submission. But Grace is forced to overcome her timidity and take up the whip herself when ex-boyfriend Aidan finds out about their relationship and decides to teach Mistress Dinah a lesson.
