Oku-sama no Kaifuku Jutsu The Animation – Episode 1 (EN)

Shion, an adult who still hasn't manifested his magical powers, is entrusted to a young couple specializing in magic research for treatment. After a pivotal incident, his mana finally awakens—but he can't control it properly. The healer wife, Rui, steps in to personally oversee his recovery and training. However, true mastery of magic requires Shion to mature sexually as well. Rui, being a married woman, draws a firm line against taking his virginity herself. Instead, she agrees to prepare him thoroughly through hands-on, erotic guidance—from basic sensual education to advanced techniques in pleasuring a woman—on the condition that it stops short of full intercourse until he's deemed ready (or perhaps finds a partner). As intimate "healing" sessions intensify, boundaries blur, temptations rise, and Shion's magical control improves alongside his carnal awakening. Will Rui maintain her marital vows, or will the close mentorship lead to deeper forbidden connections? This fantasy hentai OVA explores themes of mentorship, desire, and growth in a magical setting filled with steamy wife-student dynamics.
