Reika may be an agent, but she's actually quite easy to catch thanks to her overwillingness to surrender if she's disarmed. It's a safer approach than trying to take her by force, otherwise things have a tendency to blow up mysteriously. She has two different outfits: Her classic outfit and her Castle Shikigami III (CS3) outfit. In her classic outfit, take advantange of her thighs, hips, butt and all of the exposed skin just ripe for a Foaming. In her CS3 outfit, bind her legs under her skirt to allow it to sway and give nice views of her thighs when she struggles but also be sure to give her butt some squeezes. Either way, give her a gag that allows her hair to flow freely as it bounces nicely when she struggles.
