Inaka ni wa Kore Kurai Shika Goraku ga Nai - Season 1

Following an unsuccessful search for employment, a man has relocated to a rural area to live with relatives and taken a position as a private tutor. His pupil is a young woman named Saya, who outwardly conducts herself with propriety and refinement. However, during their private lessons, she is unable to restrain her physical urges. She opens her undergarments and pleads with her tutor to reward her. He proceeds to instruct her comprehensively in sexual matters, acting on his own desires as her body becomes increasingly stimulated. Her vocal expressions are set to resonate once more this evening.
