John's shoulder moved back to Pam's touch, though he barely slowed in his feeding. He focused his influence as Pam suggested, working the woman in his grasp and influencing her until he felt her start to tremble in his hands. He capitalized on the rush as he felt her heartbeat start to pump fiercer, despite the blood loss, and after a moment the rush of adrenaline and shudder he was looking for coursed through the slender blonde's frame.
It was then that John forced himself to relinquish his grip on the human. After all, they weren't looking to practice disposing a body. Not tonight, anyway.
As he pulled back blood trickled down his chin, but apart from licking his lips John ignored it, instead leaning in to heal the puncture marks on the woman's neck. It took a moment longer than it might have for Pam or Eric, but when he was done the fresh wounds were closer to fresh scars, and he licked the last of the blood from the woman's neck before catching her as she went limp. She was still making soft noises that generally would only be heard in the bedroom, instead of on a park bench, but John only smiled at her and pulled her close to support her. His own body felt truly fed and strengthened for the first time, between the synthetic drink and this hunt he'd been able to practically gorge himself, without risking the life of the human in his arms.
He turned and looked at Pam, fangs still out and blood trickling from his chin.
"Don't think I could manage another bite," he said, touching his stomach and grinning at how full it felt. His body rejoiced in the ample supply of food and he took a moment to appreciate the energy and sustenance before nodding.
