When a young,attractive girl, usually in Jr. High gets dirty for the first time with an incredibly hot boy. At first she loves it, as he rubs up against her, fingers her, and inevitably gets a massive boner. After he's done with her though, she experiences nausea, shivering, and shortness of breath.
