That was the beginning of their relationship and Hermione had never been happier or more satisfied. She had also introduced some muggle BDSM ideas. Such as the nipple piercings connected by a chain or the tongue piercing for pleasuring Bella. Bellatrix meanwhile had introduced her to the world of wizarding sex toys. Bellatrix had given her a collar to mark her as her slave and prevented Hermione from.orgasm by anyone except Bellatrix. Not that Hermione minded, she had fallen hard for her mistress.
