Kreacher inserted the tube easily not needing to worry about floating a retaining balloon, the magical tip was safely seated in the prisoner’s bladder holding the urethra totally open. Kreacher watched smugly as he hijacked one of his captive’s bodily functions. He fiddled with the resultant flow of pee, checking the settings range, spanning a painful trickle to the wide open gusher setting. Next he checked his favourite functions of the catheter tip, verifying that the internal integrated balloon features work not only in blocking urine flow, but the setting that forced the hidden internal balloon to inflate uncomfortably to maximum girth. Then he tested that the pulse settings worked to his satisfaction, checking both the tube and indwelling balloon could vibrating both separately and in tandem. He turned off the vibrations instead focusing on the weight setting of the balloon tipped catheter. He liked the way the heaviest setting caused stressed noises to erupt from Hermione’s unconscious mouth, with regret he switched the setting back to its lightest weight. He idly thought about running through the final setting of hot, cold and electric shock, these were always the best setting to break a recalcitrant prisoner, the human body always proved fallible to such grotesque torture. Kreacher’s better judgement told him he should wait until his captive was awake to fully enjoy these dehumanising games. Besides he knew he was running short of time so once he checked that he could fit a sound flush up the freshly lodged tubing, he was satisfied the insertion was a success. He opened the catheter to the gusher setting knowing that it would be shut for the entirety of the next training session, the prisoner could void her bowels overnight if needed from now on. As he cleaned away the last of his gear, he gave the potion tube feeding Hermione’s gag a enthusiastic squeeze, wanting to force feed the captive as much liquid as possible. The thought of her incontinence pleased him greatly. He gave his victim a hearty pinch to her posterior before leaving his victim to the nightmares pumped into her dreams, alone and silent in her prison save for the faint buzzing of the attached vibes. She was completely unwitting of the Time Turner function of the room and the companionship of two hungry dementors who feasted on her misery.
