Hermione was in a world of pain as her parents worked methodically to remove all her teeth. She felt several times that she was about to pass out due to pain, she couldn’t fully understand the function of her collar but it seemed to force her back to wakefulness whenever she went too close to the edge of a momentary respite in unconscious oblivion. To enhance her misery, Snape set the bullet’s vibrating setting to randomly buzz in her sore arse, ordinarily he would have installed a thrusting dildo, but he felt it was important to not give his captive too much distraction that might detract from her current abject predicament. This misery should be savoured. Snape knew he could manipulate Hermione to the precipice of orgasm. He would not let her reach the pinnacle or gain any relief, he wanted to torment her for as long a possible. While he was a little disappointed at not getting a clearer view to watch Hermione’s ruined face as the parents continued their work wrecking her mouth. He was quite excited to watch her pussy clench and spasm, due to the sensitivity cream he lathered earlier. He liked to soak all his sex toys in lust potions which he could see was going to drive his prisoner mad with unwanted and unfulfilled desire, as her meek sobs accompanied her parent work.
