Rydia isn't one to allow herself to be taken easily when taken by force, but she will surrender to people who persist when asking her after a few times. Her outfit makes her a delight to look at and even nicer when she's tied properly, so use a shibari to emphasize her chest and hips while allowing access to rub her hips once she's secure. She'll also have a lot of exposed skin remaining to be Foamed so feel free to use plenty of that too. When it comes to her gag, emphasize either her eyes or her lips while keeping anything under her hair. She may sound defiant every once in a while, but won't make any serious escape attempts so long as things don't go too far.
