I know the jokes are about Tina's titanic titties, but, damn, Otoha is massive too. Just look at page 8.
But, yeah, overall, this chapter was funny and cute.
Actually seeing Tina trying to stuff herself into that shape wear makes it really clear how painful her every breath has to be.
I do agree I would have liked to see the "new money vs old money" scene in the anime.
It's kinda funny that Lilisa, the one who has this "rough and tough" background, is the one who can't defend herself (Otoha has a bodyguard for that).
The audience sure has fallen for our girl band full of sweaty lesbians.
Of course it's just a joke. These women are clearly just so moved by the music. And nothing else:

Even 23 chapters in, I can't decide whether this is supposed to have an actual plot, or if it's just a way for the author to share his guro and rape fetish.
