But what she didn't realize was that where she had landed was right next to Trina's bag.  As the other girl squirmed away, and as Hitomi drove her higher and higher, closer to orgasm with every thrust, her hand darted out, grabbing the end of her wand from her bag.  Pulling it, she took a deep breath, broken slightly by light squeals, and flicked it at Rika.  "P... Petrificus Totalus!" she managed to get out before she dropped the wand and let out a muffled scream, muffled because she had just bitten down on her arm, as she came, her body jerking as her folds clamped down on Hitomi once again.
