Secretly starting a part-time job without her husband knowing, Reiko works as a married woman in the adult industry, opening her body to pursue fleeting pleasure. Filming was permitted under the condition that actual intercourse is prohibited, but unlimited ejaculation is allowed within the time limit. Though she is begged to allow bareback penetration, creampie is strictly forbidden. She chose to begin this job for one reason—to fully indulge in her own pleasure.
