I finally understood why my husband had been rejecting sex with me. Curious about where he was going, I changed the direction of the dashcam installed in the car to record the interior. As a result, the footage clearly captured the sight of someone writhing inside the confined space. The raw, documentary-like video revealed his inner conflict and desire. Then he said, "Listen... this must stay a secret from your mother." With those words, the forbidden relationship between father and daughter, recorded on the dashcam, feels terrifyingly real.
