In an unguarded moment, a husband's world shatters as he witnesses his wife, dressed in nothing but a revealing negligee, being thoroughly pleasured by another man. Her lover, a friend from the gym, has her bent over the couch, pounding into her with a fierce intensity. The husband, hidden but close enough to hear every wet slap of skin on skin, watches in horrified fascination as his wife's body responds eagerly to her lover's touch, her moans filling the room as she claws at the couch, desperate for more.
