Not my ex Girlfriend! She bit me incredibly hard while i was kissing her the first time we were in her bed. Her character completely changed from loving to this spiteful psychopathic face contorted with hate as she tried to break the soft tissue of my lips on two occasions before she stopped as i tried to move away. I wondered if she was into some kind of mutual sadism but it only went one way. She apologised and said you don’t like me biting you and i thought who the hell likes to be bitten that hard; and she went back to being loving and sweet again and this mask could be turned on or off i would learn almost on a whim.
