HANBRA NIKKI (Patreon)

Can't stop growing, won't stop growing >:3

And just for funsies here's the inspiration for her (potentially outdated) bra size: 

The 34 being the band size was inspired by Hitomi Tanaka, Nikki has a fairly slim and petite build, which works nicely with her T cup bust size, which was inspired by Himiwako, who is a nice, gigantic (for a human) size.

But as the pic shows, it seems that even that size doesn't fit dear sweet Nikki anymore, seems that the only bra she can trust now is her handbra, but even then, they almost seem too small as well...
