Damn that is hard to choose.
The one most often at the top is being with a woman who loves bi guys and loves when they take cock, human or animal, and she wants to do it together. Preferably we would have 2 dogs so we could both suck and get fucked together side by side, both turning each other on watching. Asses up in the air both knotted side by side, and when they finish we both clean each other up with our mouths. I love the idea of beasty sloppy seconds. I want to be under her while she is knotted in her pussy or ass and be there to catch the cum as it bursts out when the dog slips out, and then she leans up and sits her pussy right on my mouth and pushes all the rest of it out. Then I fuck the hell out of her animal cum lubed holes and leave her leaking my own big load.
