I do have a few experiences.
Was at my sister-in law place once to pick her up for a family outing. As she was not ready , I went up and waited for her with a drink.
From where I was sitting I would see her room with the slightly ajar door and I saw her walk out from the room bathroom clad only in her towel.
Next the towel dropped and she was applying lotion and make-up in nude !
HAd at least 10mins or so of "free show" before she was dressed !
As she was coming out of the room I made my way to the toilet to PCC on pretense that I have stomach-ach.
