Premise

Sora Nezu is shocked to find that his childhood neighbor and crush Suzune Nekogami has become a sexy, tanned gal teacher at his high school. While she is serious and strict with him during class time, she flirts with and gets him aroused outside of the classroom. His female classmates and teachers also show erotic interest in him.

Characters

Sora Nezu (根津 宙 (ねづ そら), Nezu Sora)

As a child, Sora used to be taken care by his neighbor and crush “Suzu-nee” when he was young, but rejects her outwardly when they were taking a bath together and he got sexually aroused. Now in his first year at high school, he tries to reconcile their relationship, but when she behaves erotically around him again, he gets aroused more and cannot stop thinking of her.

Suzune Nekogami (猫嚙 すずね (ねこがみ すずね), Nekogami Suzune)

Sora’s former neighbor, she used to have a friendly and proper appearance when she babysat and played with him until she was rejected by him for inadvertently sexually arousing him. In high school, she pursues a gal lifestyle and bleaches her hair blonde with ganguro (dark skin) complexion. She returns as Sora’s physical education / health teacher, and the advisor of their biology club. Outside of class, she teases him with increasingly erotic activities short of intercourse, wanting him to admit his perversion.

Samejima and Kamoi

Sora’s guy classmates, they form a biology club with Sora and Maina, with Suzune as their advisor.

Maina Uzuki

A beautiful high school gal who also has a social media following. Because all the school boys fawn over her except for Sora, she shows interest towards him and joins the biology club. But when he accidentally falls on her in an awkward “lucky pervert” manner, she then becomes aroused whenever she thinks of him, and acts upon that when alone, intoxicated, or in close contact with Sora. She is jealous of Sora’s relationship with Suzune.

Mamiko Hitsuji

The school nurse and Suzu’s former schoolmate. She likes to experiment with different fragrance oils and uses Sora as a boy toy. Some of the chapter titles refer to her as Mama-sensei because of her airhead-like motherly demeanor, glasses that she cannot see without, clumsiness and voluptuous chest. She used to be a delinquent gal in high school.

Aoi Althea Blancheval

Althea-sensei is an English teacher and advisor for their English & Social Studies (ESS) club. She started at the same year as Suzune and views her as a rival. Her first interactions with Sora was also inadvertently erotic.

Tsukasa Saginomiya

Tsukasa is introduced as a school prince who represents the ESS club in fighting against Sora at the school festival. However during the match, when Sora accidentally tears open Tsukasa’s jacket and realizes that Tsukasa is a girl who has bound her breasts, he protects Tsukasa from having that known.
