Draco quickly pushed his wand back into place and saw out of the corner of his eye that Granger went rigid. He had to focus hard on the cauldron in front of him, switching to read the potions book next to it on the table so he could hide his face behind it. He could see under it, that Granger’s legs were rubbing together. He stood back up and watched as she whipped out her wand and muttered the counter spell. Disappointed for a moment, he decided he would just keep turning them on. Maybe she would think they were malfunctioning or something. Granger looked around after the second time, but by the fourth time he thought she might have  assumed, as he’d hoped, that her knickers were having some type of adverse reaction to the potion they were brewing. On and on it went through the rest of the class, and Draco could tell that Granger was now in a right state herself. Her chest was flushed, a bit of perspiration dotted her brow, her hair had started to float a bit. Draco wasn’t sure if that was from the heat of her body or if it was her magic.
