Rena Ozaki plays a married woman overwhelmed by daily stress, who becomes addicted to masturbation. Even her attempts to relieve tension through exercise fail, as she inevitably gives in to her urges and pleases herself. When a man finally takes her, her pent-up desire explodes uncontrollably. She greedily sucks a huge cock, begs for relentless thrusting, and in the end, even accepts her son's dick. Her young, pleasure-addicted pussy drips with wet, squelching juices.
