Your wife’s friend has seen how you’ve been looking at them, and set up a trap for you a piece of malware disguised as an antivirus software that they recommended to you. It allowed them access to your PC to see your browsing history and then remotely send their webcam to your desktop, live. You could turn off your PC and ignore the obvious attraction you have for them, or you could sit back and let them talk you through all the fantasies your wife ignores. The choice is clear!
