Time to leave, fast forward

You've thoroughly enjoyed tying up and using both Sabrina and Katherine but you're spent and ready to head home, recharge and play again another day.

You untie Sabrina's hands and tell her that once you've left, she has permission to remove her blindfold and untie her sister. Because she's been such an obedient slut for you, you tell her she's allowed the next day off. However, you make sure she knows that its her job to keep her sister in line. If Katherine disobeys in any way or tries to find a way out, Sabrina will be the one you punish.

You head home and collapse onto your bed, falling asleep almost immediately, dreaming of the tight cunts and asshole you've enjoyed today.

Sabrina seems a bit distracted the next day at work. You have to finish an intern project with her by the end of the week and she approaches you around lunchtime to ask if you'd like to start working on the project after hours. Is it time you made yourself known as Sabrina's blackmailer?
