Mikuru figured there was something wrong with just standing here and watching the white bunnygirl getting fucked, but she couldn't bring herself to look away.  Nor could she hide the fact that she was becoming highly aroused, thanks to the curse, as her nipples started poking out underneath her bunnysuit, and there was a slight wet spot between her legs if anyone looked closely enough.  She began to moan softly, fidgeting and shifting her legs to try and stimulate herself, only barely able to keep herself from just dropping to the floor and pleasuring herself right there in the store!
