I honestly kinda wish Ichika was a bit more active. Like, I get that she's the "Bottom" in their relationship, but it's like she ceases to be a complete character during their sessions, if you get what I mean.
This relationship and the roles of both girl reminds me of Yamada and Kase-san. Shiine is somewhat of a cool sporty tomboy like Kase, and Ichika is more of your physically weaker wife type like Yamada.
On Kase and Yamadas first time Yamada wanted to be taken by Kase and just laid back, similar to here.
Lets just hope Shiine doesn't become as possessive as Kase. 👀
