During the long holiday, I invited the girls for a home drinking party! While the King's Game started and things were getting lively, there was only one super plain girl mixed in! And the last order is for me and the plain girl to live together for two days and one night!? I thought it was too awkward... but it's a plain girl who doesn't refuse! Furthermore, when a King's Game for just the two of us starts, it turns out that she has hidden big breasts!?
