I once had a hook up with a guy that had his dog barge into the room we were fucking in and proceeded to have a huge pee on his floor next to us while we were in bed having sex. It was a male dog. Peed like a female dog. Was it even pee? Dunno. But the damn dog was looking at us as it did that. Next thing you know of course the guy starts talking with his dog and saying oh no! So that killed the fun right away and I got out of there quick. Have never had sex with pet owners at their houses since. I would always invite the guys over to my place if they had pets — cats or dogs. All the same.
