When we got her from the pound, she had just had a litter, and we have a feeling things weren't consensual. We're bringing her crate just in case.
Unless she was tied down, which is done sometimes with dominant breeds to have a "natural" breeding, it was consensual. From all I have heard a female won't let herself get mounted if she isn't ready.
