Bath vs. shower

The little things you pick upon. I got home from work after Kate was entertaining her bull Morel. One thing I have picked up on over time is she was having an after fucking bath as opposed to a shower. This tells me she probably took him anally as opposed to just vaginal fucking where she would likely just shower. Just a pattern I have noticed over time. She confirmed this is usually the case when I asked. I suppose it's all the extra lube etc.
