" Please Mistress, I’m so sorry, please let this dumb cunt, enjoy the munificence of your magnificent sex". Narcissa played an Oscar-worthy role, pretending to mull over whether she would let her student eat her out. Again, she deployed the dopamine antidote, this time she gave a double dose, to bring on raw withdrawal straight away. It gave the begging of her new pet a more insistent edge. She allowed her charge to muff dive after lapping up the increasingly desperate sounds of pleasure. She reached for the control galleon, setting the dopamine dose to be slightly lower (she wanted her whore to work hard) and she pushed up the intensity of the sphere inside the prisoner’s sex and adjusted the tightness settings of the nipple and clit caps. She liked the hum of pleasure that drifted up underneath her when she gave her coveted good girl affirmation. The slave underneath her had a truly talented tongue. She switched the message projected into the Mudblood’s head to be the mantra of "Property of Voldermort, Property of Slytherin’, as the clever tongue brought her closer to her own climax, before alternating to "Muddy love’s Mistress’s pussy’ as the internal message playing in her toy’s ears just to keep things fresh. She removed the setting that had been blocking the prisoner’s climax. She could feel the Mudblood’s efforts redoubled as she heard her mistress fiddle with the tin. Narcissa knew she was so close now to reaching her own completion, she ordered her pleasure pet to vocalise her thoughts, allowing her to climax to the sounds of captive to confess her love for her new Mistress, as Narcissa brought her living sextoy to her drug-assisted climax, pushing her plunger filled with the raw dopamine potion straight into the control port on the Mudblood’s collar.
