"Do you trust me?” I asked him. "Yes," he said. "Absolutely." I clenched my nails into Mica's side, and his back arched. It was the clearest invitation I'd seen from him and, I suspected, the clearest invitation he knew how to give. If he even knew that he was giving it. It can take a lot of time and experience for a submissive to learn what they want well enough to give good feedback for it. It's one of those submissive skills that people don't think about enough, because for some reason we're always too busy teaching dominant skills. I kissed Mica again, and tore into his back. He was ready for it. His breathing fast became irregular; he gasped; he shook in my hands. After a while, I pulled back and simply observed the intensity flooding through him. His body undulated like a wave. "I knew you were dangerous," he breathed. "In exactly the way that I want.” "Dangerous," I repeated. I hesitated.

I pushed him a little farther. I only used my nails, but you can do a lot with your nails. I said his name, over and over. He struggled, he fought his own body. I observed the struggle and saw myself in it. "I know," I told him. Eventually Mica said, quite seriously, that he wanted to stop. I was certain that he could take more. A lot more. I might have been able to convince him to continue, and had him thank me for it later. But he needs to know that I'll respect him when he says to stop. Also, in a somewhat self-interested way, I don't want to set a precedent where his boundaries are entirely nonverbal; where his limits depend on my capacity to see through him. Maybe someday, when we know each other really well. Right now, it would make it too easy to seriously harm him... and for him to hate me afterwards. So I stopped. "No one has ever touched me so deeply, so fast before," Mica said, lat
