Azu-chan Amatsuki, who has a fair-skinned plump body and a cute smile, fiercely attacks her childhood friend! Azu has loved Seigo ever since she was a child, but she can't tell him honestly.

However, Azu thought that she could not back down at this point and tried to change Seigo's feelings for her, who loves butts, by wearing her extreme panties.
