A completely subjective immersive experience of a slut x otherworldly situation depicted in the Mirai. The situation you fantasized about has become reality!! A Kokoro-pounding AIAV. The protagonist is an unpopular occult otaku. He thought he didn't need a girlfriend or friends, but feeling the limitations of being single, he decides to summon a succubus using a magic book and occult knowledge he found in an old bookstore... He unexpectedly summons a busty succubus...!! "It's been 200 years since I was summoned to the real world. Let's get as much life force as we can." The succubus that appears is more erotic than he could have imagined... Climax!! And a squirting orgasm!! Semen is injected into the succubus' uterus many times!! Is it a dream or an illusion... a life of sex with a succubus. Production and copyright KM Produce Co., Ltd.
