Saimin Datsujo 3 ~Subete ga Boku no Jiyuu ni Naru Sekai e Youkoso~ Kurihara Shizuru Hen

Synopsis

Club advisor and recently engaged female teacher, Kurihara Shizuru.

A bespectacled, slightly gentle beauty with a plain yet popular demeanor among students. She is well-liked and has received congratulations on her engagement, but her fiancé is a bit of a mama's boy, and she's anxious about whether she'll get along with her future mother-in-law.

Yuto is Shizuru's younger sister, and occasionally hears about these concerns from Yuzuru, who also drops by the literary club. At first, he genuinely intends to encourage her, advising that it's important to self-suggest that things will work out fine.

Regardless of the content of the conversation, Shizuru is genuinely pleased to be encouraged. Yuto finally tells her it's a charm and gives her a light suggestion not to bottle up stress.

Some time later, while alone in the clubroom, a gloomy-faced Yuzuru appears. When Yuto uses an artifact to coax it out of her, she reveals that Shizuru seems to be masturbating quite intensely at home, and she's worried that something might have gone wrong with her.

Realizing it's the effect of his suggestion, Yuto reassures Yuzuru and decides to hear Shizuru's side of the story as well. Using the artifact to probe her true feelings, he finds that she is indeed troubled by the marriage, and contrary to her gentle demeanor, she harbors intense inner desires that she hasn't been able to satisfy, leaving her sexually frustrated.

So Yuto decides to help relieve Shizuru's pent-up frustration through hypnotic suggestion. Depending on Yuto's choices, the path may lead to involving Yuzuru in a sisterly threesome route, or proceed down a route with the lewd female teacher.
