Nothing mattered but the flow of blood- past his lips, down his throat. Euphoria suffused him as he drank. His gulps were syncopated with Elisio's heartbeat, just a half-second off- enough time for the pumping blood to reach the wound and then his ready mouth. His fingers gripped the older boy's shirt like iron talons. When Lazzaro broke off, Matteo shifted without spilling a drop, taking up more space. He still had to stand on the balls of his feet and lean in to reach Elisio's throat, but he had much better leverage now.
Slow it down. The words were an intrusion, felt more than they were heard. If it had been anyone else, Matteo would have been too lost in his first true feeding to hear them. From Lazzaro, though, they were undeniable. If he had not been so consumed, he might have been annoyed at the distraction. He complied, but only barely. Maybe one gulp every other heartbeat. As his feeding grew less frenzied, it did seem more enjoyable. He could feel his mouth filling, feel the muscles in his throat working, feel the waning struggles of his prey. The body he had latched onto didn't even register to him as Elisio anymore, at least not at the moment.
Three more swallows then finish.
For all the control he usually evinced with his distant superiority, Matteo had none at the moment. The command from his sire battled with his primal hunger, and his hunger seemed to be winning. There was still blood to be had. Why should he stop? The aftermath didn't occur to him. He wasn't concerned with murdering a former friend or burying a body. Still, every second he spent in defiance of Lazzaro's edict made the weight of the words heavier, like thick chains draped over his narrow shoulders. Eventually, after a full six gulps, it was too much. He fell backwards, unbalanced, stumbling into Laz. His lips were wet with blood, but he wasn't quite the mess he had been in the hall of the nest.
Elisio was another story. The ragged puncture Matteo had created began oozing blood down his neck, into his shirt. It was the sort of injury that would likely require stitches, if no supernatural fix existed. The tall, muscular young man slid down the wall, in shock. He sat on the ground of the alley with his hands around his legs, eyes glassy, bleeding. He didn't seem aware of his surroundings.
Matteo suddenly felt tired. Not full, but content. Dawn was approaching, and he'd drunk nearly his fill. He righted himself, licking the last of the blood from his lips. Slowly, awareness returned. He felt Laz behind him, saw Elisio on the ground. He frowned.
"I would have killed him if you hadn't stopped me," he said softly. There was no trace of guilt in the words, only the wonder of realization. He looked down at his fingers, which were still curved claw-like, and then relaxed them. He turned partway, presenting Lazzaro his profile, mouth now free of evidence. "What do we do with him now?"
