"I will be restricting your movement for your next orgasm," he continued. "I have some ideas of what to use, but as you have been so very well behaved, you may request your preference." She looked around the room, observing men and women in various positions, bound with metal, cloth, leather, or ropes in some combination. There was something frightening about the chains... an appeal was there, but not to try it here. Maybe privately, however. Handcuffs she could probably manage, though again she would prefer to be alone with him if she was going to be bound by metal. Something about the cold rigidity of the material made her wary of submitting to it in a room of strangers.  Looking around further, she saw a woman kneeling on the floor, shackled to the support behind her. Her arms were locked in place and her head leaned back against the wall while her partner thrust into her roughly, fucking her face with abandon. Hermione swallowed. She wouldn’t want to do that with an audience, but... her gaze flicked to Snape’s face and he lifted an eyebrow in amusement. "Noted," he said in an undertone. "Keep looking."
