A married woman's nipples becoming erect and exposed is a characteristic of the Azato type. Many may not know this, but in fact, these women intentionally show off their hardened nipples to signal their desire to be seduced. This gesture can be seen as a sign that they want a cock inside them. Once you understand this, go ahead and take her right away. Even if she protests with "No, stop it," that reaction actually means "Don't stop, this is exactly what I wanted."
