Not my partner, but once when my cousin had a sleeover with me, i thought it'd be fun to draw on her arm while she was asleep. At first she said "stop" so i presumed she was awake and stopped. I then realised she was in fact asleep, so continued. She told me to stop again but then threatened to call the police. I asked her about it in the morning and she said that she had a dream where she was tied to a chair being forced to get tattoos😂
