Down the rabbit hole further.

Katherine had woken the next morning after the operation and was still sore from the **** she had suffered but she still had to go to work. She showered and dressed and ate a light breakfast before heading out to her car and onto the office. When she arrived she headed to her office and noticed that Isabella was not at her desk and it was only when she entered her office did she notice Isabella behind her desk watching a video of the night before. Katherine blushed as her knee's turned to jelly and she almost collapsed as Isabella noticed her and smirked" Seem's little piggy had a busy night but at least you made some money" Isabella got up from Katherine's chair and headed out to her office and after five minutes returned with Katherine's coffee and placed it on her desk. Katherine noted the coffee was black and Isabella smirked saying"If you want cream you going to have to earn it" then ordered Katherine onto her knees and grabbed her hair.

She **** Katherine's head between her thighs and pushed her lips to her moist pussy and told her to start licking. "You can suck my orgasm but do not swallow you can add it to your coffee." Katherine started to lick teasing Isabella's pussy sending tremors through her body as Katherine licked faster and faster. Eventually, the pleasure built inside Isabella and she rocked her hips and then spasmed as her orgasm flowed from her pussy flooding into Katherine's mouth. She pulled Katehroine's head from her pussy and directed Katherine's mouth to the coffee and told her to drop the cum into the hot liquid. Katherine had **** and Isabella's cum mixed with the black coffee then Isabella used one of Katherine's pens to stir it mixing it together and told Katherine to enjoy. She watched as Katherine lifted the cup to her mouth and drank the mixture baulking at the taste but having to swallow letting it slide down her throat.

Isabella then dragged Katherine into the outer office which was fortunately deserted and pushed her under her desk with also luckily was enclosed so Katherine could not be seen. Isabella then sat and kicked off her shoes and started to rub them all over Katherine's face forcing her to smell the mixture of leather, nylon and sweat. Saranne stopped by asking for the chief but Isabella said she was out of the office while pointing her fingers to indicate she was beneath her desk. Saranne smirked and just said that if the chief wanted more undercover duties she should stop by her office. Isabella **** her toes deep inside Katherine's mouth leaving them there relishing the licking tongue. She looked down and saw the tears and smeared makeup on Katherine's face and smiled." Tomorrow piggy you should come to work in civilian clothes instead of your uniform and make sure you look sexy. Jillian stopped by next and asked if her sister was in and again Isabella told Jillian that she was out of the office all day while pointing.

So it was that Katherine spent the entire day beneath Isabella's desk and beneath her sweaty feet being humiliated. Isabella would occasionally pass a file down for Katherine to sign but she had little time to note what she was signing. Meanwhile, Jillian had gained access to Katherine's bank account depositing a large amount of cash via the internet. Jillian was happy her sister's downfall was shaping up very nicely and could not wait until the final act when she would be rid of her goody two shoe sister. Isabella finally let Katherine up from her desk after she once again brought her to a shuddering orgasm and dismissed her back to her office. Katherine washed her face and reapplied her make up then noted that it was home time so she left her office. On the way out she noticed that Isabella had already left for the night. At least Katherine would not have to endure the humiliation of walking past her secretary as she left the office and got into her car.

Meanwhile, a phone rang.
