>>55828447>More about your sisterShe started to bud at 7, no big deal at first, just as small size as a nickel, then it got wild when she hit 9, they just rapidly grew out of nowhere, growing pain is real. At 9, her breasts are more elevated and developed but very pointy and puffy. When she reaches 10 like May/Haruka her breasts are fuller, and rounded but still have puffy bits, meaning they are not done growing. No bra on her but I did measure them just in case, she's super short and very skinny, and her cup size is 30C.
As an older sibling, is nice to have a little girl with big breasts. Super rare to have one, all my friends were jealous of me having a very adorable little sister.
For my little sister, I felt sad, I could feel her pain and struggle even when she looked down at her feet. Having big breasts is not easy but it's really nice to look at sometimes.
