Luke jumped slightly at the sudden swipe of fingernails, feeling like a razor had been run over his wrist rather than someone's nails. Before he could say anything, though, D's lips were over the cut, drinking from his wrist and...

...oh.

He had thought it was just biting at the sensitive flesh at his neck that had stirred something in him, but something about D standing there, his cool lips against his wrist, drawing warm blood into his mouth, just did something to him. It was taking him everything to focus, that he just couldn't lose it, because D needed help and he was here to get that help. He had left the offer of help open because that was the kind of person he was, that he couldn't turn away someone in need; this wasn't about the things that got him going at all.

Luke tried to look away, shifting in his seat, trying not to focus on what was happening, but it was impossible to not focus on it. D was lovely on a normal day, but seeing him with his eyes glowing red, touching him, drinking from him... oh his heart was definitely pounding in his chest, and the blush that tinted his cheeks red was impossible to fight against. His breath started to come out in a shuddering gasp, and he was very, very quickly losing his control.

"D-D..." he breathed out his name, sounding more like a plea.
