Kreacher went to complete his last solitary tasks. He worked a small anal dilator into Hermione’s back door, her tight sphincter rebelled fruitlessly against the latest intrusion but Kreacher was focused on his goal and he didn’t mind applying force to this problem. It annoyed him to think he had to start at the smallest probe, he worked a small crank causing the girth of the dilator to increase, the pear of anguish opening itself outward. This began the remedial steps of stretching the unconscious witch’s ass, but it was not the only accessories that Hermione would need to unwittingly wear as she was put down for sleep. Kreacher added small vibrator vibe to the captives nips and clit. While the House Elf did not agree with mollycoddling the trainee, he understood how important it was to use additional stimulation to keep the captive’s body discombobulated. The final addition was the gift Kreacher was most looking forward to bestowing, his rudimentary knowledge of human anatomy meant that he was the only house elf currently allowed to do the procedure. It had taken a handful of muggle guinea pigs to prove his acumen, but the Engineer had assented to his readiness, providing him his own special kit, the piste de resistance was a souped up version of a catheter. While Kreacher enjoyed the sheer torture of the more severe rigid Muggle versions, like most things, the magical version was so much easier and flexible to install, his victim would not be aware of this insertion until the training plan called for it.
