Remus might have found a lot of things to say, but that was all gone when Sirius asked him if he minded being kissed again. Why would he mind? "I don't mind." He blushed slightly because he didn't know that something that seemed so impossible could happen all of a sudden.
He moved closer to Sirius, "I don't mind at all." For now he was not going to worry about how to explain the fact that he was a werewolf.
