Hitozuma Gakuen: Itonami Shidō de Chōkyō!? Hameochi Suru Seijunzuma

Hitozuma Gakuen: Itonami Shidō de Chōkyō!? Hameochi Suru Seijunzuma is a Japanese adult visual novel with an NTR (netorare) plot. It features full voice acting for the main character's wife, Hina Satonaka, only.

The story centers around Hina, a loving and devoted wife to her husband, Katsuma Satonaka. Hina married Katsuma three months ago, and although their marriage has been happy, Hina is self-conscious about her performance as a housewife, especially her poor cooking skills. For the sake of Katsuma and their future child, Hina decides to attend a cooking class to improve her cooking. Her search leads her to a vocational school named Hitozuma Gakuen ("Married Woman Academy") with a suspiciously low cost of admission. While at first the school seems like exactly what she needs, everything changes when Hina is raped by her male instructors after getting drunk at a school party. Convincing her that improving her sex skills will also benefit her marriage, Hina's instructors coerce her into performing more and more sexual acts, pushing her into a decadent spiral of lust. In the end, she will have to decide whether to reject her infidelity and return to her husband or succumb to lust and remain at the school.
