Here's what I don't get: how do we determine breast sizes for Kyonko and Itsuki? We don't exactly know how huge their cocks are, so how? It's pretty much universal to assume Mikuru has a horse cock, but why is Itsuki often depicted with larger breasts than Kyonko?

Pic is random from my trap/reverse gender folder. Hopefully it's related.
