I think condemning a kink like this as "sick and disgusting" is rather narrow-minded, particularly when our membership is not opposed to drinking piss, blood, cum from strange men, and eating shit. I don't think any kink is too perverse, as there is always someone that may enjoy it (disclaimer: I'm not advocating pedophilia, snuff, or real rape. I'm talking about consensual, extreme, kink-play).

That being said, I've had a fantasy or three about a scene involving animals. It usually involves me watching rather than receiving, and it usually involves larger animals rather than dogs. I can say with certainty that I wouldn't partake in a scene like that in real life, but I am rather turned on by the idea of it.

Regarding abuse, I think if the animal aproaches on its own accord and arousal to partake in a sexual encounter, then no, its not abuse. But the minute that an animal is forced, it becomes abuse (pushing or pulling a dog onto a waiting female and/or holding him there, restraining a dog so that a man can penetrate it, tying a goat in with a rope so it can't get away from molesters, corralling a reluctant horse so it can be mounted from behind, or held still so someone can use his penis to penetrate themselves... you get the idea). To me, the idea of a man penetrating a dog is particularly abusive, because a dog's vaginal tract is very small, and cannot accomodate the size of a man's penis (hello vet tech training!). Any other thoughts?
