Ben's not the only breathless one, Sadie's expression as the kiss ends is completely blissed out because good god had she missed being able to have a good, hard snog. It was the only thing she could say that she missed with Ben though it was often barely worth a thought considering how wonderful their relationship is. The question about her purring takes her completely by surprise, Sadie stills for a second as she processes it before her face erupts in a blaze of red that would certainly cover her ears is she still had them in what is definitely the largest blush Ben would have ever seen on his girlfriend.

"W-well it's a semi-conscious sort of thing and so I can do it purposefully but it mostly happens automatically which then requires conscious effort to stop and there seem to be lots of causes like being safe or happy," Sadie rambles away, her gaze sliding to the side of Ben's face, "SoIpurralmostallthetimeI'mwithyou."
