In the dimly lit room, John's heart raced as he watched his wife, Lisa, undress for the courier. His cock twitched in his pants at the sight of her perfect body bathed in candlelight. As the stranger, Jason, kissed her neck and began to caress her breasts, John felt a mixture of jealousy and arousal. But when Lisa moaned softly and wrapped her legs around Jason, John had to force himself not to grab his own cock. He bit his lip, wondering how far this would go. Moments later, Jason entered Lisa from behind, and she arched her back in ecstasy. John struggled to keep quiet as he watched them fuck passionately on the bed. His wife's gasps and moans filled the room, making it hotter by the second. As he watched them together, John felt a strange sense of intimacy filling his heart with jealousy.
