There was indeed much more foreplay involved in this particular session than the others, but the others didn't seem to care as much about it in the moment. All of them enjoyed it, but it wasn't always something that won out over their initial carnal desires. In the case of Robin, she was being offered quite the standalone experience, and as such she wouldn't be backing down from offering the same. So after baptizing Charlemagne as Kazuhiko had been, she allowed herself to relax only so much as to draw her feet up and down the length of his cock simultaneously. She watched as he devoured that which her body had offered so freely and found it to be quite attractive to see. She couldn't help but be consciously turned on by such a vision, nor would she do anything but appreciate it and try to return the favor.
And so those two feet continued their work until such a time as she felt the outpouring of almond milk flavored mana all the way up her form from those little toes all the way up to her white hair. "Sugei! It's so much♪~" she chimed happily. Her tongue escaping her mouth to lick her lips and even her fingers drawing themselves through her a bit to place it on her tongue. She'd even find herself absently winking down at Charlemagne, content to see what would be next after that first expulsion but one couldn't help but notice that this was such a perfectly posed moment. It was like she fully intended to be seen both like this and in the completely innocent way she'd been seen before. Whatever was next on Charlemagne's list, she'd leave herself quite open to it, she assumed he still intended to do something with that leg of hers. The other girls were watching and could only appreciate the things happening in front of them, and all the while Nym was trying to shrink but she still seemed quite large currently, it seemed she was still actively metabolizing. And while that happened Charlemagne and Robin could continue on.
