Read a lot about guys getting screwed by dogs and not liking it, or liking it at first, but complaining about getting hung to him. It feels good at first, cause his d*** is small, kinda like getting finger fucked. But within about 8 seconds of that good feeling his knot is rapidly swelling, and in another few seconds, when you feel something different, its already too late. His knot is already too big to pull out, when he stops h****** its full size and he has you hung to him. All that’s left is for him to dismount and you spend the next 15 to 25 minutes getting filled with his s****. And feeling his huge knot, better hope you’re in a place where nobody can see.
