Amanda - Bondage, pain, spanking, whipping and orgasms

I have a beautiful ebony girl tied up with leather straps on my bed. This image alone is a summary and a calling card of what is to come.
When I touch her for the first time, I think she shows fear, but also libido. So I will suppress this libido through fear and then stimulate her libido to leave her in a confusion of sensations.
And I start to do this with pain, beating her face and crushing her breasts with my hands, causing extreme agony. And I continue with the pain like a whip, whipping her buttocks and breasts without much compassion.
After all this pain, I reactivate her libido with the electronic stimulator, and she reacts exactly as I expected. She holds on to the pleasure it provides, and I allow her to experience this sensation for a very short time.
And we return to the pain and humiliation, until I leave her in the dark, tied up and in conflict with her feelings.
