I was in the bath with DP, nothing sexy just washing and about to watch a programme on the tablet.
As I was finding the episode DP unexpectedly poked my vagina, in surprise I aggressively splashed her in the face with water to make her back off and was annoyed at her. I told her it shocked me (as wasn't even looking in her direction so no warning) and said she had to apologise to me. I said it could be considered assault nd she replied with "Oh, Bath..." and a withering look.
She has refused to apologise, and is now in a strop as I was "horrible" to her.
