Late that morning the package Jessica had been eagerly awaiting arrived. She had ordered a second strap-on exactly like Magic, except black instead of blue. She plugged it in to charge and sat back to think about how best to break it in.
An hour later she convened the whole household in the bedroom and instructed Jane and Marie to get into 69 position on the bed, with Jane on top. They obeyed unquestioningly, of course. Jessica got out four sets of handcuffs and cuffed Jane's wrists to Marie's ankles and vice versa. Then she unplugged the new strap-on, helped Celeste into the harness, and flipped the switch.
"Ooh," said Celeste, giggling as the vibration from the strap-on stimulated her pussy. Jessica equipped herself with Magic and they went to town, taking turns filling Marie and Jane's holes from both ends. When they were finished there was a limp pool of sweaty, satisfied female on the bed, and Jessica and Celeste had each had several orgasms of their own.
After uncuffing Jane and Marie, Jessica told them to make sure the strap-ons were cleaned and charged for that evening. Janice was coming over and Jessica wanted to show her an especially good time.
Jane and Marie frowned at each other. It was becoming clear that their mistress had a new favorite, that Celeste was being treated differently than they were. They didn't really resent Celeste, because they were both already a little in love with her too. But it did seem like they were going to get stuck with all the dirty work.
