You cover your ears at the scream, your giant and monstrous frame making her upset but no matter how much this transformation has changed you physically you hold on to the man that you used to be. You aren't some beast to rut and rape, and your own preferences aside if she was in place like this then there was probably something she wanted or needed. You try to speak to her but your voice has been stolen from you. Only a bull's cry escapes from your lips and the noise appears to make her reconsider her decision to be near you. Spinning around and attempting to run, she ends up tripping over her own feet, the result might be humorous if the cause of her panic weren't you in particular.
Still it wasn't safe to let her run around like this and so with only a few steps forward and a hand outstretched, you grab hold of the woman, her struggles intensifying against your gentle grip but proving ineffective against the 12 foot tall minotaur. Holding her out in front of you, you motioned to her with your hands to calm down. She wasn't really getting it though and so you gave her a light pat on the head, conscious that with your new found body and strength that it would be so easy to hurt her if you wished and hoping that she would pick up on that as well. The voice in his mind spoke to him, urging for him to use her as a plaything but the voice was just that, it didn't compel him to act against who he'd always been and so he set the girl back down.
Wide eyed and realizing that the minotaur in front of her was not hostile, though lacking in the current ability to communicate she gathered her thoughts, "I'm sorry for reacting like that. I was afraid you were a monster set here to prevent me from reaching the treasure inside."
You shake your head, you don't know of any treasure. Your presence in this room was just an accident. The voice disagrees with you but you don't have time to question it.
"Perhaps you were cursed and trapped here then, the tunnels go to many rooms, most are unoccupied, but I heard rumors there was a treasure located somewhere in all of this that would grant a person's wish if they could find it. I admit you are very large, probably too large for most of the paths I've gone explored so far but if you would be willing to protect me maybe I could help you return back to normal?"
