Aside from Aki and Zany who are a bit of a musclehead, they had already understood this before Andrew's question was asked. In fact, Andrew had already thought about it, which was why he proposed this to the emperor and the others.
He had only asked the question so that there would be no doubt among his confidants, but he was being too condescending. All of his companions except for his two muscle-headed wives, could understand this immediately.
With that defined, the meeting ended and everyone returned to their activities. Andrew and his wives before really wanted to go crazy in the room, but with the emperor's summons and so on, they had already lost the desire.
Plus, their kids were there, so they decided to have a quiet night and even decided to sleep with their kids that night. Fortunately, the room where Andrew and his wives slept was thoroughly cleaned every day, because with everything they do there every night, they couldn't let their children touch that bed.
