Draco moaned softly as he touched her wet knickers and she kept jerking him but slowed down considerably. He saw her staring down at his cock and grinned. He liked that Hermione seemed to love his cock. If he was honest with himself, her pussy was an incredibly hot sight too.
Despite his bravado, he knew he couldn't just skip potions and he doubted Hermione could just skip Artithmancy. His hand continued to tease her wet sex through her knickers. "Is this what we are going to do?" Draco punctuated his question by pressing his fignertips and her knickers slightly inside her pussy.
The idea of her stroking him while he fingered her until they both came would be hot but the idea of being inside her again was even hotter.
"I don't think so. I think you need to take it off, Granger." He was already unzipping her skirt and pushing it down over her lips.
