Well, my now ex and I were in the BDSM lifestyle together and played hard in quite a few spaces. We watched porn and explored ideas. One day we were perusing some porn and I think we clicked on a large object insertion video link, that's when we discovered a specific porn site with beast content and we both paused and looked at eachother and waited to see who would say what first. I said, I'm all into watching this. She said really? I said yep but I'm good with not watching it if you're not interested. After less than a minute she said yes she'd like to watch something because she never saw it before. That began the fantasies and porn watching, and the serious discussions about getting a K9 and training it. Alas, never got there.
