Kaede Oshiro, Haruka Megumi and Mizuki are three hot siblings. They are so lovely and fun to be with. But one thing about them is they are so competitive. They are always trying to beat the other sis no matter what it is. As it happens, an old school friend named Manjiro is visiting Kaeda today. The other siblings remember Manjiro well from their old school days. Since he is Kaeda’s guest today, and she is out of the room, her two siblings have decided that they need to do their best to seduce him so they can have him fall for one of them rather than Kaede. Of course this competition can only be won by the girl that gets Manjiro to fuck her and unload all his cum inside her pussy.
