sister daddy

When a cross-dressing man sees himself as a father figure to a girl roughly his age, such that they could be sisters.

I met this billionaire the other day and he offered to be my daddy. But he was wearing a cocktail dress and looked like he could be my sister. So he’s my sister daddy <3 I asked him to marry me but he said no
