I need more of Kira being dominated by the other two. Maybe both at the same time, as a reward for Sakura being a good girl and Kira being a bad one. xD I just like my PC getting dominated. And Kira is cute, which helps. :P
One thing I've wondered is throwing Kira to the Incubus and Succubus, but because of her lack of experience, ends of getting dominated by them in a rather rough way. :P
Maybe could unlock something about Kira enjoying rough play in the future, so you can add scenes like that with a happier tone (at least once the scenes are done) or something? Just throwing ideas out now, considering the 'upgraded' version of rough play is one of my own big kinks. xD
