I tried to think really hard on an answer that isn't "post-rehabilitation domestic slice-of-life" but I have to own my truth. the second most specific scenario I think about with them is "clumsy attempts at BDSM/CNC because Yui is struggling too much with her conscience to be able to hurt Touko the way that she wants her to (yet)" as well. I guess these scenarios could also be for not-fem shuadashu too, but I honestly think about them more as women than not for some mysterious reason, and I think the latter scenario would carry much more weight when they're sapphic women, especially.
