Ryoko grinned as she watched the enchanted rope quickly bind the twins.  She wasn't quite sure if Rayne would go along with her plan, but she was pleasantly surprised he did, even more so when he managed to execute it so perfectly.  She sauntered up to the one Rayne wasn't up close against, slightly disappointed that they seemed to be enjoying things at the moment, and decided she would try to change that.  First though, she wanted to see what they thought about another kittygirl being intimate with them, as she began to lightly run her fingers along Bonboori's lower lips.  She didn't push a finger inside her yet though, simply teasing her, sometimes brushing a finger against her clit.  She watched the girl's face, looking for any signs of her arousal.
