I can understand what you're saying, I had this girl who referred to me as "Daddy" and it kind of freaked me out too.
She was quite normal at the beginning, I requested nylons and heels, she obliged, when she showed up she was in jeans though and said she wanted me to watch her put them on, she did a great seduction job, she took everything off erotically and put the stockings and heels on very erotically,
When she had them on she strutted around in the room and then she looked at me and started talking to me in a kids voice and calling me daddy, it freaked me out that I asked her to get dressed.
She seemed quite surprised, she slipped her jeans on and we talked over a glass of wine and she left.
I still paid her for her time
