Confront John with the video.

You decided on your next course of action. You had the video stored on a USB device which you pocketed, and walked up to John's office. You opened the door and stepped in without knocking.

John looked up at you as you walked in. The alarmed expression on his face only gave you a sense of satisfaction. You sat down in the chair in front of him.

"Hi John. I think we need to talk." You stated calmly. You hid any emotion from your face and voice as you spoke to him, and felt overjoyed as he watched you cautiously.

"Steve... Of course, what's on your mind?" He feigned interest as he closed his laptop and leaned forward, his fingers interlocked as he looked at you.

You realised that you might need to act a little for him to react the way you wanted. With that in mind you snarled and spoke with a certain aggression.

"You know what. How fucking dare you." You snapped at him, a little more anger in your voice than you intended.

"How dare I what?" He sat back and pretended to be shocked. You noticed his nervous glance towards the closed door.

"You know exactly what. You come into my home and fuck my wife?" You stood up as you spoke, both hands on his desk.

"I don't know what you're talking about! I suggest you go back to your desk, and we'll pretend this never happened." John replied.

"I have it recorded you fuck." You took out the USB and slapped it down on his desk.

His gaze slowly drifted to the USB. He hesitantly picked it up and looked at you.

"Think I'm lying? Go ahead." You spat angrily.

John plugged the USB into his laptop and lifted the screen back up. You saw his face pale after a moment, his eyes widening. You almost smirked. He then looked back at you after a moment and had regained composure.

"..and?.. So what?" He smirked at you, daringly.
