To cover up her husband's serious mistake, married woman Natsuki is forced to clean up the mess by submitting to her boss. While her husband is away on a business trip, she's suddenly subjected to intense anal training. With merciless deep throat forced upon her, Natsuki is left with no choice but to obey. The demands escalate rapidly, leading to cruel double penetration with brutal anal sex and deep-throating. Her anus is stretched wide open by a thick dildo, transforming her into an all-access sex slave and cumdump. In the end, she's facialized with a powerful cumshot, left broken—her body and soul unable to ever return to normal—after this ultimate, degrading experience.
