Sex slave: Carolin

Being unfaithful to a guy compared to being unfaithful to a girl is perceived as being less dangerous. Many men sleep with their girls to remind them that they are still the top performers in the bedroom and that's the only form of retribution they offer. None of the women forgive in the same manner.
For instance, Kathia punishes Carolin by causing her suffering; she twists her nipples forcefully and handles her vagina with severe intensity. She refuses to cease until she observes regret written all over Carolin's face.
