Sirius heard the words, but in his mind they came out as something a bit different - more like whatever you say, dear. He knew that when it came to lovemaking he was likely to get his own way, even if it were at a party in a stranger's home. The important thing was that they did it together. They had lost time to make up for.
His mind was already going to his wardrobe, which was limited by anyone's standards. He had lost a great deal of weight in Azkaban, and a great deal of his clothes did not fit, but he wasn't exactly in a position to run out to a tailor, either. So he would have to do with what he had, or take a chance on conjuring up something. Which may or may not work. He was a wizard, not a tailor, after all.
"I wonder," he ruminated, tapping his index finger against his lips, as he pursued his own thoughts. "Do you think maybe we could come up with some clothes from the 60's? Maybe we can stop by one of those resellit places and see what they have?" He gave his mate the benefit of his puppydog eyes again, coupled with a wistful smile.
