DASS-793 A two-day, one-night lovey-dovey creampie sex session with a secretly lewd, plain-looking girl with big breasts who suddenly became close through a King's Game.

During the holidays, I invited some girls over for a drink at my house! As the King's Game begins and things get exciting, one very plain girl joins in! And the final command is to live together with the plain girl for two days and one night!? I thought it would be too awkward... but the plain girl doesn't refuse! And when the King's Game begins with just the two of us, I unexpectedly discover that she has hidden big breasts...!?
