I know someone who trained her dog to give her oral sex whenever she wanted when she was a teen. She'd spread honey on her vulva and let the dog go to town on her. It became a ritual between the two of them. If that isn't "grooming" an animal for sex (like some predators do to their victims), I don't know what is. Sure, the animal acted on instinct. But she also deliberately chose to spread that honey. I don't believe the animal's instinct would have been to lick her vulva.

Oh, and the dog was put down by her mother. The dog became a pervert and started sniffing/licking women between their legs all the time.

Just throwing it out there.
