Dunno if Methonium wanted to gives us a tactile idea in this chapter, but he really did it, all the girls give that impression of touching dough wrapped in a bag and then making Boss body like the finest wood carved by the most skilled artisan.
OH SWEET BAYBEE JAYSUS! This! This is why I read this! For the love of god someone adapt this into an anime, make a Collectors Edition Bluray and sell me it ffs!
And the funny thing is, Methonium is well aware that the characters have become a lot more buxom since the first chapters. He's even posting comparisons on his Twitter account!
@shiftysands no, they are much bigger than before. If you check the author's twitter feed, they highlight the "evolution" of the measurements - specifically, Erufuda's.
