Right. Not much choice about the definition. I also commented that perhaps muskan was thinking more in a different context, but hasn't returned to say yea or nay.
Unless one says what one means by a term, or tells us the context in which s/he is using the word, all we can do is presume one means (one of) the standard definition(s).
When "whore" is used as an epithet and not to mean prostitute, it usually means you are accusing said person of being willing to sleep with anyone if the price is right (usually not monetary.)
I don't see that in muskan's treatise either. She's trying to relate it to an emotional context. But it's still apples and oranges. Some slaves have no emotional connection to their masters save the desire to serve. And sleep with no one but their masters (if at all) so can hardly be equated to someone who will sleep with anyone at all... so I still don't see how you can talk about one in the same context as the other... without some more context to the statement/question.
