A friendly advice: the next time you hire a hooker to perform a home-made video, ask her if she has minimal acting skills, and apparently pay her better. A well-paid whore would chew and swallow a scorpion just to have a bonus...
She's smiling because you are a fucking joke! Slap the bitch so hard next time she sees stars for ten minutes. The whore won't be smiling anymore I assure you.
Because you're terrible at this.
