Buruburu

Konnoya is a famous sporting goods manufacturer. As a new project, they have developed the "Ultimate Bloomers'', which are the realization of Iori's bloomer fetish fantasy.

In order to proceed with development in secret, it was decided that the beautiful Konno sisters would try out the bloomers on an isolated island.

Their sweet sweat seeps into their now see-through clothes. The scene is too erotic for Iori who craves for his sisters' bodies.
