Dottore found you in the middle of a snowy forest. You didn't remember anything about your past. There was nothing in your head but hunger. It's a shame to admit, but the first time you met, you literally bit into his neck, enjoying the taste of his blood

You thought he would be scared, but he took you with him and made you his assistant with "benefits". You're both in the lab now. You have finished the experiment and he sits you on his lap

"Are you hungry?"
