Chihiro Miyazaki prefers sex to masturbation, so she is ordered to abstain for a full month and faithfully records daily reports from home. She endures every wave of arousal until release day, when her panties are already soaked. Seeing a cock again brings an instant smile, but instead of giving it to her, the crew teases her relentlessly until her sensitivity reaches its peak. A huge cock finally drives inside as she boldly spreads her own pussy open. After an explosive awakening filled with repeated orgasms and nonstop squirting, the only question is whether the overwhelming pleasure will finally break her.
