My interpretation - They just fuck, without working.
It gets gloomy, dark and then pitch black. Vivian will fuck them all, or in other words: everyone will fuck her, except for two. The office workers and the niece, the party guests, the mayor, the girlfriend, the son's roommates, half the class and the basketball team, the janitor and the teaching staff we meet later

, the car mechanic, and of course, the homeless man who appears in the final act. God, I hope I forgot someone!
Yes, we still need a doctor and a policeman.
She'll be crowned Slut of the Year. After that, Myriam will be history. Hutch will be forced to watch everything. Muhahaha. Hutch will also be tasked by Christian with ordering bulk orders of blue pills and Addyi so no one has an excuse or shirks responsibility. Everyone gets a turn. The tissues will be sold out at the drugstore for a while after this. The spacebar and Ctrl will be used diligently and glow. A great, creative story; it has the potential to be a huge success. I love the plot.
