Riri, a married woman, went back to her in-laws' house with her husband, but he had work troubles and left early. Alone with her father-in-law, a man with insatiable lust, she embarks on a three-day affair that she can't tell anyone about. Even after morning arrives, her father-in-law continues to penetrate her relentlessly, driving her to the brink of death. Despite feeling guilty, I embraced both the pleasure and the infidelity.
