Anon is macrophile, which means he loves giantesses.
One day Anon gets home from the tiring work and wants to chill out. He sits in front of the computer and watches some crazy MLP videos on PornHub. And one particular video gets his attention, the most viewed video on the site is about Twilight Sparkle, who satisfies herself while destroying a city. Millions of people watch the virus video every week and Anon later finds himself in a dream-like situation where his hometown is under attack and a massive purple creature wants to make him satisfied. What a weird day, huh?
