"Her G-Cups are too big" says the last page.
Yeah, no shit.
That's because those ridiculous fat-filled balloons are not even close to "G-cups;" they are more like N-Cups, or possibly Q-cups.
I live with a 36KK/38K Cup, and they are nowhere near that size... and I mean "Nowhere Near."
At least get the cup size right, if you're drawing a Tits-Based Manga!
