Since it's canon that Rika frequently masturbates what does she use to do it? Does she just use her hands or something else? Can she hear Hanyuu's moaning while it happens, does she think about her at all? What does she think about when doing it for that matter? Does she do it in the same cabin with Satoko sleeping right beside her, or does she sneak off outside to do it in the night? Or is it something she can get away with doing while at school in the bathrooms or pretending to play with something like a gym climbing rope and feeling it between her legs as she climbs?
This is important
