WHEN THE LAST OF THE CLIENTS HAD GONE, SHIRLEY WENT ABOUT HER DUTIES OF SCRUBBING AND CLEANING THE EQUIPMENT AND FLOORS OF THE DUNGEON.
As one can imagine, there was a good covering of cum and stuff over pretty well everything. The smell of which is acceptable when fresh but once rancid develops a strong oder of ammonia.
While Shirley was on her hands and knees scrubbing the stone flag floor, Zelda was in the office, counting the takings. She was pleased with the tote and set the cash in the safe.
Smiling to herself she returned to the dungeon. Standing over her slut, she was reminded that Shirley's punishment had yet to be completed.
The five inch steel heel of her boot found the back of Shirley's neck and forced the slut's face into the muck on the floor.
Having ensured a face full off suds and cum were deposited over its face, she grabbed it by the collar and hauled it across the whipping horse. Shirley's head hung down over its side and was held there by a leash to a heavy weight. Zelda then tied the ankles to rings on the legs which were splayed to a spread of 5'.
Lifting the slut's hem to check the damage done during the first part of its punishment, she saw the the butt plug and cock cage were still in place. She needed access to both organs and so released them.
She pulled Shirley's meat down between her painfully splayed thighs and removed the plug. The slut was well dilated and Zelda took pleasure from the gaping ring. She had been strutting around with her strap-on threatening many human apertures all through the eight hour gig. Although many would have enjoyed being fucked by Zelda, she kept that commodity for very special occasions. Now she wanted only to fuck her slut.
Shirley felt the great dong entering her. Zelda shunted slow and firm. Each time going a little deeper.
Shirley would know when full depth had been achieved once she felt the leather clad thighs of her Mistress against her buttocks.
"Fuck me Mistress ! Fuck me ! Yes ! Fuck your slut! "
The pumping continued to a steady pulse as Shirley felt Zelda's hand start to wank her hanging meat.
