Reiko's husband is on a business trip, and she repeats boring days with housework, childcare, and part-time. Recently, I've become friends with Azuma, a student who spends time at my part-time job. - Taking advantage of her husband's absence, she accepted a time-limited affair. Since then, the two have been repeatedly infidelized in between work. Reiko's body drowns in dense pleasure in a limited time and is violently disturbed. Before I knew it, I felt aching all the time and continued to get hot and wet in search of a young man's.
