"Sit". Snape’s command was difficult for Hermione to comply with, as her hands were useless bound to her collar, it was a struggle to get herself upright and it only served to slosh the liquid she was painfully retaining. Without ceremony, Snape injected a syringe full of liquid into Hermione’s catheter, filling another orifice with Snape’s mystery greasy liquid. She tried to remain motionless even though she felt fit to burst. Snape waited for the cover of the new waves of cramps before he installed the final accessory, Hermione could feel a sharp tug on her g-spot as it was encased with the small golden sphere that Snape had retrieved earlier. Snape waited a few minutes watching the slow undulation of Hermione’s body as she rocked herself slightly trying to relieve the cramping pain. He was alive to the possibility that he might have missed the g-spot with his last spell, but after he ran a few diagnostic wand waves he was sure he had the item successfully installed. Voldermort might get the full benefit of the potion he had slathered all over the prisoner’s body, but Snape felt a perverse surge of pleasure that he had conquered a small but vital bit of the prisoner to call his own.
