Slightly taken by surprise by Amanda's question, Don didn't answer immediately. Because of her playful nature and lack of embarrassment regarding adult topics, there was a chance she was being serious.
However, imagining a situation where an aunt, after not seeing her nephew for years, decided to give him a peek at her breasts seemed too comical. As Don thought through all this, Amanda spoke before he could come up with an answer.
She raised her hand and waved it in front of his face while laughing mischievously. "Oh, look at you, just kidding, Donnie," she laughed before adding, "I'm glad to see you're still shy when talking about such things."
Don inwardly sighed in relief that she took his hesitation for shyness rather than him actually thinking of saying yes. With the awkward situation avoided, he replied, "It's not that I'm shy; it's just that it's not something you'd typically discuss with your aunt."
