Her body has changed during her time here serving her Mistress. She had thought she had excellent stamina for Quidditch. But, her Mistress is insatiable and has trained herself under Bellatrix to hold off her orgasm. She has taken this training and made it harder for her slave Ginny to bring out her pleasure. Ginny doesn't really mind all that much. She gladly spends hours between Hermione's legs with her tongue trying to draw out orgasms. She also like Hermione now has pierced tongue and nipples. But, her Mistress went even further and had Hermione's clit pierced. It was slightly unfair Ginny thought to be punished for how she could not hold off orgasms. Ever step the intimate piercing was rubbed against and she was in a constant state of arousal. Her anus was constantly filled with a plug or other toys. Hermione had found or invented she wasn't quite sure. A vibrator toy that simultaneously filled her pussy and anus. Then her Mistress would make it vibrate throughout the day at various intensity by her magic.
