This series just get gayer and gayer. I love it. In the beginning it was so mild that the yuri tag was missing. I still wonder about Kasumi and Sakurako's relationship, they're kissing, wearing matching panties, cups and clothes; they even sleep together every night, but neither of them made it official .-.
Totally platonic.
Also totally asexual.
Actually, it does feel like Kasumi might be asexual to me. Someone above pointed it out and when I thought about it... She's never much interested or excited by sexual contact or content. She's almost unaware of how she might affect someone sexually (as an asexual person who grew up with an accommodating but lackadaisical parents or friends might) and remember, just because someone is asexual. It doesn't mean they're aromantic. There's a lot of correlation between the two. But asexual people can feel romantic and even sexual pleasure. It's more that their ability to love and be loved isn't wrapped up in the idea that sexual attraction is the cornerstone of a relationship.
In any case Sakurako is clearly thirsty as heck so if Kasumi is indeed ace, there's gonna be a long conversation about boundaries and intimacy In their near future.
