Most Casto's are some bad ass motherfuckers and don't give two shits about what you think. They have giant ass cocks and fuck more than a jack rabbit with a hard on. If you fight a Casto be prepared for a hell of a hospital bill. They are naturally attractive, very seductive, and very strong. They like to spend they're free time rubbin' snuff or vaping. They also like to fish, hunt, and go muddin'. That's only when they're not fucking your mom.
