Yes

The day passes slowly but eventually you arrive at the end of the work day and the full-time employees have all gone home.

"Ready to start working on the project?" you call over.

"Yes, let's do it!" Sabrina replies.

The two of you order some takeout Chinese and settle together in one of the offices to get to work.

"Sabrina just one thing before we get going," you say. Sabrina looks up at you inquisitively, and you pull out your phone. You begin playing the video from the previous night where Sabrina is eating out her sleeping sister's pussy.

Sabrina gasps and her hands fly up to cover her mouth in shock. She looks at you with apprehension, unsure of what to say or do.

"I know there must be a thousand thoughts flying through that pretty head of yours," you say softly, before hardening your tone, "But I'm tired of playing this game. Now you know who I am and who you must obey."

Without saying more, you reach down and start un-zippering your pants. Its a test to see how Sabrina will act, if she thinks she is truly in too deep to back out, despite the revelation her blackmailer is a coworker she thought of as friendly and harmless. You pull out your cock, Sabrina still staring at you silently.

"Come over here and suck this cock before we start on the project," you command.
