Her endurance had improved, able to run faster, over greater distances. No where near the physique of a Quidditch player however, because Harry gained on her quickly. Thinking on her feet, she cast a Motus jinx, which simulated the effects of an Earthquake. She had never used it before, only just reading about it the day prior. She put much of her magic into it, too much in fact. The ground shook violently, throwing both Hermione and Harry off of their feet, and their wands flying. Hermione tried to scramble to her feet, but Harry leapt on her back, bringing her back to the ground. He rolled her on to her stomach, and began to pull her pants over her struggling hips. Hermione fought hard, throwing elbows, and bucking, trying to get him off of her, but he just continued working at her pants, pulling them down to her upper thighs.
