Eightman-sensei no Okage de Kanojo ga Dekimashita!

Tanaka-san likes SEX, but the men she meets these days are just not enough. While browsing through erotic manga at a bookstore to make up for her frustration, she runs into her teacher, Sato-sensei. He seems like a shy guy, but they hit it off and Tanaka is tempted. Tanaka sees that Sato is a virgin and invites him to a hotel room. Sato-sensei is almost overcome with desire, but still tries to maintain his proper position as teacher and student. But Tanaka-san is determined to take his virginity and his beautiful cock, which is on the verge of busting from his self-control.

This love (of cock) is real!
