Last year, the little-known idol group Tsuri Bit got a lot of attention at a live appearance where 14-year-old member Sakura Ando demonstrated that she was not only lovely and lively, but also stacked.

They were surprisingly subtle with this year’s summer-bikini song (pretty much every idol group does one of these now…). Rather than giving her jumping jacks and other obvious titty-action moves (like Erika Yazawa in pretty much every Idoling!! video), they simply put the rest of the group in bikini tops that masked their relative development.
