Here comes my favorite eternally young and *virgin* av idol Tsubomi!  In this video, she becomes a cum taster and takes a kind exam to prove her skill.  She blows a guy, gokkuns and tests the cum, and guesses what he ate before the shoot.  Did you know your cum taste changes depends on what you eat?  Watch how well Tsubomi does on this test.

As if gokkun is not enough, Tsubomi receives cum bath after this.  Enjoy!
