Two co-workers who met and fell in love at work end up becoming newlyweds and share a romantic evening together.

However a new co-worker at the company is going to attempt to have some of the new bride to himself

All it took was a single moment of weakness, can anyone blame her? Her husband has been so busy...

A single photo captured in that moment would go on to be the blackmail that would have her surrender herself to him in every way imaginable.

Every time Yurina is with her coworker, she can’t help but recall how she was before being blackmailed and fucked by him.

Yurina hides and dissimulates before his sexual demands, receiving repeated cumshots in the office, in the meeting room, in the bathroom, and on the train. Her body has become so sensitive to her coworker that she gets horny immediately when he approaches.

Yurina, a married woman, finds herself in a compromising situation during her daily train commute. While her husband embraces her, a young coworker physically harasses her. Over time, these encounters begin to change her, eroding both her loyalty and sense of reason. When her husband goes away on a trip, the coworker seizes the opportunity to intensify their relationship, promising to stop if she rejects him once more. However, his passionate advances are so overwhelming that Yurina can no longer remain the same woman.
