"Tomorrow's presentation and the mannequin hasn't arrived!?" Mao Kurata has successfully developed an incredibly lifelike mannequin—so realistic it's nearly indistinguishable from a real human, thanks to cutting-edge technology. With a promotion on the line if the presentation goes well, her husband is devastated when a sudden mishap prevents the mannequin from being delivered. Seeing his distress, his wife proposes a bold solution: "Why not use me as a replacement? If the mannequin looks just like a real person, no one will notice the difference." Determined not to let her husband's hard work go to waste, she steps in to take the mannequin's place at the presentation—but things quickly take a sensual turn as hidden desires surface, leading to passionate encounters and creampie-filled moments between this devoted milf and her grateful husband.
