[Kuro can only barely focus on his words, too focused on the rush of Heine in a way that goes far deeper than a voice. Blood doesn't have a a different flavor for Kuro, not really. It was that same metallic copper taste on the tongue, hot and slick. But all blood contained life, and this was distinctly Heine's, no one else's. There's tension and curiosity, but not fear.
It's that lack of fear that helps Kuro ease up. Some of the trembling is fading now, and his hands squeeze Heine's shoulders rhythmically as he continues to feed, tongue and lips working at the wound a way that would definitely leave a hicky on a normal person, a good kind of sore with a sharper undertone. Another, softer groan escapes him, this one rumbling from his chest, trailing off into something almost like... a purr?
No, definitely a purr. It's faint, but it's very much there, easily felt where his chest is pressed up against Heine's. There's a flush to Kuro's cheeks thanks to the blood intake, though it might not be easily seen just yet.]
