The back of my throat is my erogenous zone… New resident doctor honoka deeply respects ENT doctor Arai. However, he harbors a deep darkness of subjecting female test subjects to 'throat orgasm research,' torturing them in the mouth until they reach climax at the back of their throats. One day, after witnessing this scene, she is forcibly made into a test subject by Arai. Enduring daily 'research' in the form of throat torture, honoka eventually begins to experience pleasure in her throat that surpasses what she feels in her deepest parts.
