"I have," Samandriel said softly. "The contract's been drawn up and combed over several times to make this as...painless as possible." He licked his lips and went to go get a glass of water for himself.
"I have a plan." He took a drink of his water, keeping himself open and casual as he looked at the demon. "You're the only being I can remotely trust who has experience in the sort of things he's likely to do to me. I don't...I'm not asking you to do them. I won't stop you, but that's not what I'm asking of you. You're free to touch me as gently or roughly as you like or not at all," not that a Master needed permission to do anything of course, but consent always helped.
"And if it's all the same to you, Master Barton, I'd...I'd rather be able to pin my thoughts on someone else while he's whipping me. I know he wants me desperate and begging and I'm only going to truly succeed at that if I can close my eyes and picture someone I have no interest in smiting, if I can focus through the pain on the sound of a voice I might perhaps one day care about as more than just an extension of my sister in a way. If I'm going to survive this, I need help and I have absolutely no one else to turn to."
