While I was translating this, I saw that the second panel mentioned a core of sorts while I was using my methods (writing the characters in google translate and running it through the context of the other text so I can adapt it and also sometimes using other translation sites.) I think I might've missed a detail and that Nutsack Maricha has two cores inside her balls, which explains why she was writhing in pain in the first place. Then again, two or three cores inside a yukkuri is insane, but I guess that leads into the awe of the woman. I might have to check it again.
A gem of the factory™ technology...!
ps:Corrected because factory was changed to processing plant.The result of blood, sweat, and hard work...!The inside of this Marisa's ball sack contains the bean paste cores.THUDPANYuYufu ♡There's 2 in total.
