Why does people keep saying "loli, loli" as if this was a loli manga?
These girls are the same age as the Sailor Senshi in the first season of Sailor Moon. They are anything but lolis.
If you don't get it, let me put it in simpler terms: ChibiUsa is a loli; Usagi is not a loli, she's a teenager. All the girls in this manga are teens as well, just like Usagi, Rei or Ami. It's not that difficult.
A loli needs to be prepubescent, short (notoriously so) and with a child body (no curves). A young woman who looks the part (happens often in manga) is a loli-looking woman, not a real loli. Sometimes, just for the fun, an author will make a loli go through a precocious growth spur -- ie, she's still a loli but gets big boobs -- but these cases are quite rare.
All MCs in Skeeter Rabbit are thirteen (perhaps more) making them legal. They can have all the lesbian whoopee they want.
