Aali's voice dropped, and he leaned forward, looming over her, and Hermione's heart beat a little bit faster. "The day i-is nearly over," Hermione protested weakly, even if, for once, her heart wasn't into her argument; Hermione had always been the logical sort, a rule-follower, and she wasn't stupid–she knew well enough what she had agreed to, in order to receive her points. But really. Even if she was as honorable as the average Gryffindor, if not so, there was no way that she would last the entire day without being able to come–without even being able to touch herself.
As though Aali could read her thoughts, all of a sudden, his hand was between her legs, pushing the device into with enough force that its vibrations were duller, heavier, and Hermione gasped, her knees buckling as she caught herself against Aali's chest, her hands fisted in his robes. "S-sir!" she managed to squeak in protest, caught between going up on her toes to avoid the sensation and grinding down against Aali's fingers. She pressed a hand to her mouth to stifle a moan, on the cusp of another orgasm, barely able to focus on what Aali was saying, and–
–and just like that, his hand was gone, and Hermione was left with the device's base setting, more maddening than intense. She stumbled back with a frustrated whimper–and this was all his fault, she thought, shooting him a stony glare. He knew that she couldn't possibly go to the nurse. The only thing worse than this entire situation was the prospect of having to hide it from the nurse...or worse, having to explain it. The nurse had certainly dealt with her share of wands stuck in sensitive places, but nothing of the kind in connection to Hermione Granger.
What she had been expecting for some time. Hermione blinked. It took her a second to parse what he meant, and she gasped, reddening even further. "Professor!" she managed, shocked. "H-how could you ask for such a thing?" As though he were so certain that she would giving something of the sort up, just like that–really, Hermione was offended. "I-I think I'd better leave," she said sternly, or as sternly as she could manage, given the way her voice hitched as the device abruptly shifted again from the vibration to the shock setting.
She would get the device off herself, she thought, as she left in a huff, albeit more than a little unsteadily. She didn't need Aali's help; she was a perfectly capable witch. She would remove the device, focus her attention on...herself, briefly, and then continue on earning points without Aali's guidance. Although really, it was a little bit of a pity; her fingers weren't quite as big as his. And his fingers weren't quite as big as...she bit her lip. What would that feel like? There were certainly a few items at the back of the catalogue she had received that would give her something of an idea, but she would have to order it and wait for it to arrive...and plastic, or whatever the wizarding equivalent would be, certainly wasn't a substitute for the real thing. At least, Hermione was fairly certain. It wasn't like she would know firsthand–and if Hermione was to be entirely honest with herself, that left her the tiniest bit disappointed. Knowledge, of course, was Hermione's area of interest.
Somehow, Hermione managed to last three more classes, even with the new distraction at hand. She tried her best to mull over Aali's proposition as rationally as she could; to think with her brain rather than a portion of her anatomy that was further south. This was a difficult task. Even so, she reasoned–was it so different from what they had been doing, what he was asking? He'd already become intimately acquainted with her. The Slytherin girls were certainly up to worse. Perhaps it would be a good thing, even, to learn from someone with a great deal of experience...and, of course, it would be a good thing to earn some more points for her house.
Hermione had certainly never envisioned using the Marauder's Map for such a purpose, but she had stormed off before Aali could let her know where his private chambers were located, and Hermione had to take things into her own hands. She had located his footprints, indicated by the A. Samara inscribed underneath them, and stolen away from her dormitory once again, trying her best to keep herself quiet as the device kept her from what felt like her hundredth almost-orgasm of the day. But finally–after what felt like an eternity, certainly the longest day that she had ever had–she stood in front of a door, and knocked.
