Bellatrix kneels as ordered. Presenting herself to Hermione as she has been taught. Her ass high in the air as commanded, as she obeys willingly. Her pert bottom available for whatever her master desires. She begins to caress and spank her. "You don't have to be so rough you know," she said, tracing her hand down her stomach to her waistband. Hermione continues to caress and spank her. Not a harsh spanking in punishment but a sexy sensual firm spanking intended to heighten her sexual anticipation. Her pleasure is her reward as she pushes her higher, controlling her orgasm. Taking her to the very edge and back again. Her sexual satisfaction is her prize. Orgasmic pleasure that is utterly addictive.
