The slut felt it's Mistress pull hard on it's cock and draw it in between her legs. Then using it as a dildo to masturbate herself.
For the first time in their relationship they were belly to belly. For the slut, this was a privilege beyond it's wildest dreams. For it's Mistress, it was just another way to amuse herself. After all, a real live dildo was a novelty!
She would make herself cum without any concern as to the emotions of the piece of fuck flesh that she was using in the same manner as she might use a plastic sex toy.
Fortunately for the slut. it reached it's climax first and ejaculated over it's Mistress's pussy. There was only a few seconds in the delivery of it's cum before Zelda herself exploded with passion. The slut's teeth gripped her nipples harder in an involuntary action as her arms went round it and squeezed it into her breasts. This orgasm was in no way to be the only one in this session. Tonight she was without all control of her lusts and needs. And the big point was...... her lusts and needs were of a truly sadistic nature. She could only achieve complete sexual gratification when her victim was totally subservient and compliant with her demands. She had found these qualities in the slut Shirley. This object whose sexuality hovered between man and woman. It was not a man trying to be a woman any more than it was a woman in a male body. It was just as it was...... an IT !
Grabbing it by the ears, she forced it down onto it's knees. She rocked it backwards and pulled it's face into her vulva, rubbing the cum soaked genitals over the sluts face until she blew another wash of her juices. This time she also emptied her bladder straight into Shirley's willing mouth.
Having, for the moment satisfied herself, she threw the slut down to the floor with contempt.
"Wash yourself slut!"she said, as she gave it a shove into the corner of the shower with her foot.
"And dress yourself. I want you looking pretty while I'm having my martini" T.B.C
