Every guy has had this dirty fantasy: the friend of your girlfriend somehow seems even more attractive than she is. Why is that? The desire to secretly cross the line and get intimate with your girlfriend’s best friend starts to consume your thoughts. As you steal glances at her, you occasionally catch her looking back. In that brief moment, you wonder—could she be interested in you too? That impure hope grows stronger. And before you know it, she’s subtly tempting you, careful not to let your girlfriend find out. Each step deeper pulls you further into the fantasy.
