OVA Ikuiku Succubus Saikyouiku episode 1

Tanehisa Busujima, an ugly fat teacher at a prestigious private academy, possessed a dangerously weak sense of self-control. Some perceived him as straightforward, while others deemed him thoughtless, always blurting out his uncensored thoughts without hesitation. He resembled a walking libido, his relentless sexual appetite seeming to seep through his very clothes. He couldn’t help but leer at the exposed thighs of female teachers in tight skirts or gaze heatedly at the behinds of female students clad in gym bloomers. His scandalous behavior had nearly led to his dismissal due to allegations of sexual harassment towards his female students. In a twist of fate, the school principal presented Tanehisa with a condition to retain his teaching position: become the supervising instructor for exchange students from the “Succubus Country.” Little known to the public, the Succubus Country was a nation solely inhabited by succubi in a realm known as the “Dreamscape.” In a secret trade agreement, the Japanese government had struck a deal with the Succubus Country to provide male energy in exchange for enhancing the sexual desires of the country to combat declining birth rates. As part of a goodwill initiative, Tanehisa, with his beastly sexual urges, was chosen as the instructor for this exchange program. While the ostensible purpose was to impart knowledge about the Material World to succubi. According to the overseeing official of the exchange program from the Succubus Country, Lima, the true objective was to re-educate the “failing succubi” who had never engaged in sexual intercourse, even in their dreams.
