Ah, now I see. Thank you for the clarification.
First, the Scripture you are referencing is not exclusively addressing rape:
---
“When a girl who is a maiden is engaged to a husband, and a man finds her in the city and lies with her, then you shall bring them both out to the gate of that city, and shall stone them to death with stones, the girl because she did not cry out [when people] in the city [could have heard her] ..."
---
At least the initial assumption there would be that the girl did not cry out because the act was consentual. However, I cannot imagine any right-ruling judge automatically having her stoned before at least asking her why she had not cried out ... for it is at least possible she had been gagged or even knocked unconscious.
---
“But if a man finds the girl who is engaged in the field, and the man seizes her and lies with her, then only the man who lay with her shall die. But you shall do no matter to the girl. The girl has no sin worthy of death – for the matter is like a man who rises against his neighbour and kills him – for he found her in the field, and she cried out, the engaged girl, but without anyone to save her” (Deuteronomy 22:22-27).
---
Overall, and regardless of where the incident took place, the pertinent "point of law" concerning the girl is whether or not she had cried out *if* there were people nearby ...
... and *not* whether anyone actually heard her. If a girl was to be found guilty and stoned simply because no one had heard her cry out, then the girl in the field would automatically be stoned for not in the first place being near enough to at least someone who could have heard.
Therefore, the girl in your scenario could not be rightly stoned unless there were actual witnesses to attest to her "I consent" silence.
