Popular actress Mari Natsuki × Himekawa Yuuna's first co-starring work! At the private Chinsabu Academy, where only top students who love blowjobs gather, they showcase their techniques in a blowjob battle! If one sucks on the ball sac, the other deeply engulfs the glans, and while one performs a deep throat from the front, the other licks the anus from behind... They use their tongue and oral skills to make men feel good and swallow large amounts of semen through oral ejaculation! If they're caught in a double blowjob sandwich by schoolgirls, there's no holding back the explosive release!
