Inviting the current top squirt actress, "Hamasaki Mao," as an instructor to give practical lessons on squirting to five men who have never succeeded. It feels good but something's off... about to cum but can't squirt... etc., while struggling, Mao carefully instructs them on how to use their middle finger inserted into the vagina. Mao herself continues practical instruction with her finger inside, truly impressive!
