"What do you want?" Emily says

"Oh, I have something to show you" you tell her, smiling

When she close to you, put play on the video of her masturbating. In the 10 minutes that the video is reproduced, her face changes from surprise and embarrassment. Then, after the video ended, she say:

"You creep! You were filming me!"

"And I have all videotaped here...." you reply, smiling.

"What are you going to do with the video?" she asks, fearful.

"That depends on what are you willing to do for me to not show the video" you say

After some thinking, Emily replies to you:

"OK, what I've to do for you to delete the video?" she asks, embarrassed and angry.
