Her husband's senior couldn't find a place to stay due to a sudden business trip and ended up staying for a few days. The senior who appeared there was surprisingly a regular customer from her delivery health service days, and Rei desperately pretends to be someone else. However, the senior who noticed Rei's existence is aroused by her mature appearance. Threatened to be exposed to her husband who hates the sex industry, she has no choice but to offer her body. She is forced to allow even the real acts that she had repeatedly refused during her delivery health service days, and her chaste chastity is quickly defiled as she is repeatedly fucked with a raw dick.
