What next event of note happens?

The start of resistance training

Lunch was eaten in silence that day. It seemed tensions were still high, and Hermione didn't want to risk making Pansy angrier. Hermionie focused on her food to make sure she wouldn't accidentally give anything away, but the spark of an idea came to her, one that she might make some things more difficult, but could prove useful in the long run...

Once they had finished, the Slytherins went down into their common room as Hermione dashed up the stairs to Gryffindor Tower.

After flashing her pussy to the Fat Lady again to get inside, Hermione reached inside her bag and pulled out a sock that had been wrapped around a round object. Hermione pulled it out to reveal the vibrator she had made several days before. It was still shaking violently, yet subtly. Hermione placed it on one of the squishy armchairs.

She looked at one of the homework tables and waved her hand wordlessly, thinking the words "Wingardium Leviosa!" She was able to make the table rise up easily enough without a wand now. She set the table back down.

Hermione took a deep breath as she touched herself enough to make her wet, then inserted the vibrator inside her vagina.

Waves of pleasure took her, but she couldn't let herself go so easily. Hermione turned back to the table. "Wingardium Levi-oh-sa," she thought with a swish and a flick of her finger. A wash of ecstasy filled her as she tried to cast the spell, and it made the table raise a foot into the air before it fell back down.

But Hermione was determined... She knew that, if her libido was her weakness, and that arousal curse would render her helpless if she was ever caught by it, she'd have to learn how to control the arousal.

Hermione's knees shook as more juices dripped from her nethers. She tried again, the table jumped a little again. Again and again she tried, getting a little more control each time until she eventually came and the table came crashing down.

She took a brief moment to breathe. She wasn't done yet. She had to keep going...
