The small camera, discreetly placed, records the unthinkable. My girlfriend, usually so reserved, is transformed into a wanton cheater. She's on her knees, taking him deep, her eyes closed in ecstasy. The room is filled with the sound of their bodies slapping together, her moans echoing off the walls. She reaches down, rubbing her clit as he pounds into her from behind. The camera catches the moment she orgasms, her body convulsing, a sight that used to be mine alone, now forever tainted by her deceit.
