"Do not move."
The young woman stood perfectly still, the razor-sharp edge of the sword in her sensei's hands only inches from her neck.
"You need to trust me enough that even when I have the sword this close to you," which he emphasized by moving it slightly closer to the tender skin covering her jugular vein, "you won't move. You won't even flinch. Understand?"
"Yes, sensei."
The tall instructor stood there for a moment, watching what she would do. She never moved, but allowed her breath to become steadier, calming herself, and getting used to the feeling of having that beautiful blade so close to her. In seeing this, Marrok stepped back, lowering the sword and sheathing it in a well-practiced motion. He drew it out of his belt, sheath and all, and, after bowing it out, carefully put it back in its place on the rack on the wall of the dojo.
Lily only barely let her shoulders relax. She knew her sensei wasn't finished with her, and was pretty sure she knew what was coming next.
Marrok turned back to her and smiled, that evil, wolfish little smile he got when he was about to do something to her that senseis weren't supposed to do to their students, especially on the dojo floor. He produced a butterfly knife from the pocket of his gi pants, showing off as he opened it, the flair of the knife spinning around having the desired effect; Lily stiffened again, unconsciously afraid of the sharp metal, and what he could do with it. He walked around behind her in a slow circle, coming to stop directly in front of her. He traced the tip of the blade lightly down her cheek. "Strip," he ordered, and she obeyed quickly, taking off everything, including her jewelry and hair tie, setting it all in a small pile on the floor, and leaving herself completely bare before him.
"Spread your legs, lace your fingers together behind you." She did so. She wasn't technically allowed to do anything physical, including aikido, with anyone but Marrok and his wife. But she would occasionally get into some just-for-fun struggles with an old flame of hers, and he needed to be sure there weren't any major bruises, or any other injuries that would hurt bad when he put her down.
Which he did. Fast. A variation on irimi-zuki, where instead of hitting her, his wrist landed just below her collarbone, and she was on her back and pinned before she knew what was happening. He took her hands and pinned them down at her sides, then gave her a look that said "don't move", and slid off of her. He grabbed the black nylon rope from the duffel bag on the floor, and bent her legs to tie them up. She started to tense her legs, but his thumb at the pressure point on her ankle reminded her that she had to behave, and she relaxed them. He tied her legs to themselves, bent up so she couldn't move them. He stopped for a moment to brush his hands down her legs, admiring the soft, pale skin.
"You really have the most beautiful skin, Lily," he said, as he ran his hands back up her legs, and over her stomach and chest. "I wonder how pretty it will look covered in red stripes from my belt." She flinched and whimpered. Marrok stopped at that. "..Not a fan, I take it?" he asked gently. Lily took a moment to calm her breathing, and to remind herself that Marrok wouldn't hurt her beyond what she was ok with. She was his sub, and his student..not his slave. There was a difference.
"Not particularly," she said in a level voice. "A belt is a bit beyond what I can take. A four-tailed medium is about my limit."
