Poor Sammy. Always looked so damn scared, every time, always did. She knew he didn't want this yet, hadn't completely found himself, found just how special it really made him, but he would. He'd find it. She hoped this would be the end of the questions, the worries, she hoped after tonight Sam would understand just what the blood could do to him, hoped he'd want that power just as much as she wanted him to have it, and since she couldn't drag another demon for him to drain, this would have to do, this staggered night of his taking her blood.
"Sit down" she told him simply gesturing to the bed, he wanted to keep this professional, get the first drink out of the way. She could do that.
She moved across the floor lifting the knife from the table, she'd make the cut again, professional.
"Until you've had enough without crossing into overdoing it. Thats the best way I think"
She lifted the knife, cutting clean into her arm, and waited, he'd decide how best to do this from there.
