I became the wife of a sex-crazed monster next door who made a lot of noise every night during sex, relentlessly pursuing her lover. (Okuda Saki, SONE-522)

Higashi, a college entrance exam candidate, lives alone in Tokyo. One day, a couple moves into the apartment next door. From that day on, every night, loud moans from a woman can be heard coming from the next room. Although it's hard to believe that these are the sounds of his seemingly elegant and beautiful neighbor, it greatly affects Higashi's exam preparation... Unable to concentrate on his studies and unable to bear it any longer, Higashi decides to complain to the couple... "Isn't sex more important than studying?" It's me who fills the desires that her husband can't satisfy... In his free time, overflowing with sexual desire, the wife greedily and joyfully enjoys the young and vigorous penis.
