Girls Get It (Back Pain) Done
They are a canon lesbian couple, so that's good at least. I do like them as characters.
But also, ow, their poses, especially Rain's (the blonde one) in the final panel. And also the "you can join in!" thing is... very of the time, for the demographic they're aiming for (i.e. unfortunately not lesbians).
