I know the focus here is on the main gag more than it'll be developing character relationships, but I'm not gonna lie, kind of a bummer to see that it seems like the author's going to be taking the "yeah they basically had sex and confessed but they're both girls so they're going to keep calling each other friends" route here.
I'd gotten a little hopeful that this series would be doing more with its characters but for now it seems like we're going to be stuck with them being props to set up different wacky fetish scenes for laughs.
And don't get me wrong, if that's your thing, that's perfectly cool! Not hating. Even as just that this series is still super entertaining, so it isn't the end of the world.
