My first story of anything. Hope someone can enjoy.
Harry had been married to Courtney for almost two years now and their marriage was going well. But lately, Courtney's behaviour had changed drastically; she was suddenly much more cheerful and outgoing, chatting with friends on the phone and walking through the house singing. Harry found her newfound joy infectious, but couldn't help feeling a bit disconnected from it all. While he loved how her mood had improved, this sudden shift in attitude between them was affecting their sex life. He enjoyed being able to talk about dresses or makeup with her - it made him feel included in her enthusiasm - but their frequent physical intimacy which Harry considered incredible considering Courtney was all he'd known and wanted for so long was quickly fading away.
One day, Harry found himself following Courtney to their neighbour's house on a day he was supposed to be at work. He stayed hidden until he saw Courtney flirting with the neighbour and watched as the two of them went into the pool. They started touching kissing and Harry could feel a strange mix of emotions coursing through him--anger, hurt, sadness, and something he couldn't identify.
Harry watched the couple leave the pool area with a burning desire. He followed them, not sure if he wanted to see or be seen, but knowing he had to get closer. As they entered Brads conservatory, Harry could hear their passionate lovemaking echoing through the air. It seemed so much more intense than anything he and Courtney had ever shared -- her moans of pleasure cutting through all other sound. His heart began to race and his skin was covered in a sheen of sweat as he imagined what they were doing together. His arousal grew as he felt every thrust, every kiss. His hands moved along his body as his breathing intensified, and before long he was unable to keep himself from pleasuring himself to their sounds of bliss. The sensations that filled Harry's body were both naughty and exciting all at once -- something he never expected but couldn't deny.
