The same old pussy and full breasts, the sounds of orgasm kept my neighbor's wife, who couldn't sleep all night, into my sexual rival. Saki Okuda, SONE-522

To prepare for university entrance exams, Higashi lived alone in Tokyo. One day, a couple moved into the apartment next door. From that day on, every night Higashi could hear the sounds of a woman having orgasms coming from the next room. Higashi couldn't believe that it was the voice of his beautiful neighbor, and this greatly affected his studies… Unable to concentrate on his studies, Higashi decided to complain to his neighbors… "Sex is more important than studying," Higashi became a married woman trying to satisfy her unfulfilled desires. Her free time and excessive sexual desire led her to crave young, vigorous penises.
