Due Dilligence (short story)

I knew when Mistress walked into the room that her last session had been a frustrating one. It had not been going all that well for her. As a young mistress she still had much to learn, and many obstacles to overcome. I had anticipathes her needs, and sat waiting on the floor for her. She needed to prove to herself that though new, she had what it took to become a grand mistress.
I spoke not a word as she approached and dug the end of her crop, still hot from her client's skin, under my chin.
„This has been a very trying evening for your mistress, slave,“ she said. „I need to release my tension. Will you oblige me or no?“ I nodded slowly to her and motioned with my hands to the chains I had placed on myself. She pulled my head back by my hair and cropped my breasts sharply.
„Naturally I will not leave any permanent damage to your fair skin. But I will punish you, be sure of that.“
I nodded my consent. „It is my wish to serve you, my mistress, in whatever way you desire.“
We spoke no further. She hoisted the chain that bound my wrists overhead and cropped me harshly. She yanked on my crotch chain, making me cry out. My reaction did much to lift her spirits.
She released me and had me dress in lace bra and panties, then made me lay on my back on the floor, attaching my ankles to the bar as well. From my vantage point I could look up through my legs and see the dildo she had fastened to the bar dangling deliciously over me. Mistress fluttered her crop around my face and tits, teasing me, then reached down and held the dildo for me. I could not reach it, so she cropped my ass sharply. I knew she would continue the crop me until I found some way to get my cunt to that dildo, but I did not know if she would allow me to come. But that was not important. Her needs must be met first.
