Wait and see if there'll be an opportunity to escape

As bad as your ankle hurts, you realize that it's best not to risk further injury. You go limp in his grip and he chuckles. "Giving up already? I had hoped you'd put more of a fight than that. Oh well. Come, let us make it so your breasts start producing some milk for me."

Your lips tremble at those words, and though you've never heard of someone getting pregnant from a Minotaur before, after being turned into a woman not too long ago, you don't doubt that there is some magic out there to make it possible. The Minotaur carries you like his bride deep within the cave. It's so dark that you can't see a thing, but somehow he can, as he doesn't fumble or trip once. Eventually, you notice a small sliver of light, that slowly gets bigger the closer you get.

With a round of a corner, you gasp as you see a perfectly lit room within the cave. Complete with a huge bed, various decorations, a small waterfall and pool in the corner, and even a kitchen. He's certainly lived here for quite a while, as you can tell that some of the decorations are at least several centuries old.

The Minotaur lays you down on the bed, and says, "Stay here. I shall tend to that ankle of yours."

He then goes over to the kitchen and starts mixing ingredients together. He has his back turned, and now might be a good time to try and escape.
