Nybras almost nuzzled into her hand when she touched his face but he caught himself, though he didn't do anything to move her hand away either. He did well to remember that he was siting next to a succubus but she did seem to have at least some genuine interest in learning from him. He returned a smile "well, I suppose it will be nice to have a pupil" he gave a weak and slightly awkward chuckle at the mention of punishing her and then he remembered what they were supposed to be doing "um, for now we should get back to this" he looked to the paper "so we need both our eyes on this at once?"
