the first time i chose a bra, and they got messed up in the dressing room.

When the bulging breasts began to grow so heavy that they felt weight on their shoulders, Ubuko and her friends were from children to adults. I'm going to run up the stairs again. A lingerie shop visited by Ubuko who are in the midst of such a growth period. A male clerk who is worried about choosing a bra for the first time in a secret room called tackling, exploits the innocent mind that does not know anything and creates as much as possible!
