The second season has finally begun! The hotly anticipated content "IKUNA" is shaking up the AV industry. Following the positive reception of the first four seasons, it's already moving to a new stage! "IKUNA" is a battle of endurance to determine the strongest AV actress in each genre. This time, it's the "Ultimate Climax Showdown"! Two of the Reiwa era's most squirting actresses will come together to challenge their limits, putting their honor and pride on the line! Coming out of the blue corner is Oto Alice, "The Strongest Golden Ratio in History. A Solo Splash Mountain. A Black Diamond. A Blonde Snake Goddess"!!! Opposing her in the red corner is Mao Hamasaki, "A Jet of Squirt That Pierces Steel. The World's Strongest Sexy DJ, the World's HAMAMAO! A Magician of Sound and Squirts"!!! The time has come for two legends, each celebrating their 10th year since their debut, to show down the line. A historic encounter between the queens of orgasms. Who will be showered with joyful drops and a splash shower? Rules: The actress who can endure the opponent's masked second man's full-force attempts to make her cum for the longest time will be declared the true endurer. Starting with full-body caresses, cunnilingus, and electric massager play, followed by a parade of intense thrusts in positions that make it easy to climax, such as cowgirl and reverse cowgirl, how long can Oto Alice and Hamasaki Mao endure? Those who can endure will be rewarded with some flirty, slutty sex, while those who cum will be dominated and masochistic in sex. Open your eyes. Look up to the sky. ...Today...it's pouring rain! It will shatter your ordinary image of sex. Tonight, the curtain will be raised on a heated battle between women.
