Okay kiddo, sometimes grown-ups have thoughts and fantasies about doing things that they wouldn't actually want to happen in real life. One of those things is a rape fantasy.
Now, what is rape? Rape is when someone forces another person to have sex without their consent. That's a very bad thing and can hurt people physically and emotionally.
But in a rape fantasy, the person who is imagining it wants to pretend that someone is having sex with them without their permission, even though in real life they would never want that to actually happen. It's just a pretend game that some people like to play in their minds to feel excited or turned on.
It’s important to remember that rape is never acceptable or okay in real life. It's important to always respect and communicate with our partners and never do anything that they don't want. In a healthy and consensual relationship, both people talk about what they want and don't want and respect each other's boundaries.
