her with the vibrator

You're sitting at your cubicle when Sabrina arrives, she shyly says hi to you again before going to her desk.

You: I'm going to use the remote controlled vibrator on you today but I want you to text me before you cum because you are not allowed to orgasm unless I tell you to. You are going to livestream yourself just for me so I can ensure you obey.

Sabrina: Ok sir, I do still have some work to do today, can you try and allow me some time to make sure I'm still getting some stuff done?

You: If you are a good girl then I will allow that.

Soon Sabrina's livestream for you is online and you begin watching, the camera angle from below her desk facing up her skirt where you can see the outline of her tight pussy. You then open up the vibrator app and turn the vibrator on low. You think you hear a gasp from Sabrina's cubicle and watch on the stream as her legs start to squirm. She spreads her legs a bit wider and you notice that she is soaking wet already. Her pussy is glistening and creamy.

Sabrina: I'm going to cum pretty soon if this thing stays on sir.

You: You're going to cum already? If you do come there will be a punishment. I'm going to keep the vibrator on for another minute and then you can rest.
