Because
1) I ALWAYS loved female animals, Cows, Deer, Dogs, name it. At first it was just how cute they looked, then it evolved in... well...
2) I always felt as i owed my bitches something, i never liked castration, the idea felt disgusting, (at the same level as disgust for people that finance the breed of genetic disasters known as pugs) but also i never knew how to arrange a "meet up" for them, so i decided i needed to fix things on my own, at first it was just rubs then and there during their heats, then a finger inside them and when i knew it i was balls deep in one of them.
3) another thing that is that, after losing my zoo virginity i looked up porn and felt disgusted how much abuse is out there, perhaps if i knew how i would like to make some kind of guides videos about making REAL LOVE to bitches.
