My first wife and I used to be naked at home. She'd wear a long T-shirt to answer the door, but for fun, she started doing it with less and less clothing: a short T-shirt showing her ass, underwear, or just panties and bare breasts, until one day she dared to do it completely naked, and since then, it's what she always did. And not just with delivery men; she did it whenever there was a knock on the door, salesmen, mailmen, neighbors... There came a time when all the neighbors in the building had seen her naked.
