This sketch was inspired by a comment I received on DeviantArt on my first Sirens Hebi No Onna sketch:
 
Adagio: “I just want a hug…”  
Aria: “Oh, Hell no!”  
Adagio: “What?”  
Aria: “Every time you make us hug someone, Sonata breathes down my neck!”  
Sonata: “I DO NOT!!”  
Aria: “Do too!”  
Sonata: “Do not!”  
Aria: “Do too!”  
Sonata: “Do n-”  
Adagio: “Girls, quiet! Don’t make me get the socks again!”  
Aria and Sonata (in unison): “We’ll be good!”
 
 
I just HAD to draw THIS exchange! XD
