Nobody

You wait several seconds for an answer but none comes. You knock once more and still no answer. You can't leave here without your jacket, so you decide to see if you can see Greg from a window.

You go around the back of the house and see catch sight of Greg in what must be his bedroom. You get closer to the window in order to get Greg's attention, but you are shocked by what you see in front of you.

Greg is sitting on the edge of his bed, as Caroline Lawson kneels in front of him, her head bobbing up and down on his cock. You can't look away, watching as one of your students takes your boss's cock down her throat. You guess the rumors of Greg sleeping with students are true after all.

You decide to move before you are spotted, and you make your way back to the front of the house. You decide to check under his welcome mat and sure enough you find a spare key. Unlocking the door and opening as quietly as you can, you sneak inside and grab your jacket off the counter when Greg's voice startles you.

"That's it, Katherine." You freeze in place, embaressed to be caught. You look up to explain yourself when you realize that nobody's in the room with you. Greg speaks again and this time you realize his voice is coming from his bedroom.

"You're so good at this, Katherine."

You are confused by the use of your name, so you creep down the hallway and stand next to his open bedroom door, listening in.

"Suck my cock like you sucked my boss's."

The realization hits you. Caroline is role-playing as you for your boss and Greg is really enjoying it.

"Stand up and strip, Katherine. I can't wait to fuck you."

You can't believe your boss is about to fuck one of your students and pretend he's fucking you. You think you should confront him, but then again you have your keys, you can leave now. It's not like he's the first guy to fantasize about you. You could just let him go through with his harmless, perverted fantasy.
