Under the direction and support of the wizards present in the dungeon lab, Hermione was arrayed into various positions to allow her parents to maul her in a succession of grossly pornographic acts. She couldn’t tell if their actions were compounded by the lust potion they’d been plied with or if the imperio curse was involved, all she knew was that her body ached all over. She knew struggling would be futile and could only endanger her innocent parents. They used every available orifice multiple times, happily accepting sex aids from her wizard overseers. When it was finally over she didn’t know whether to be relieved at having a break from her parent’s seemingly insatiable sexual appetites or be worried on their behalf now that her parents had been escorted away by the snatcher. She was struck by the worry that they might have outlived their usefulness.
