September Suggestion 19 (and a little mistake) (Patreon)

-Wosh, that's definitely not normal! I hope we haven't drink too much of this soda or else... *sad Miku sounds in distance*
Thanks for idea Trombonophone, but I clearly I messed up - I was pretty sure someone asked for water balloon Elise (and she's trying to understand how the hell she keeps being inflated), so I drew her too and made Rin mid-inflaring instead, just like you asked last time. But be sure the idea of water cooling for Rin will be drawn later, outside of suggestion box
