They're sleeping together.

Karen winked at her older neighbor. “You know what it is. We've been having an affair since I turned eighteen.”

Mr. Sawyer looked around nervously, then ran over to the fence. “Keep your voice down! What if someone heard that?”

Karen laughed. “Stop acting so nervous! You've never been worried about our relationship before!”

The older man stopped short for a moment. “Well, that's true, but I'm nervous now. I don't know why. Maybe you should come over here so we can talk about this.”

“Right away... Tony.” Karen turned around and walked toward the front of her house, making sure to move her hips in a way to really show off her ass. She was wearing tight jeans shorts, and she knew they showed off her assets. She glanced back and saw that, yes, Mr. Sawyer was looking at her butt in a way he never had before. She almost giggled as she walked around the fence and into his yard.

“Come inside before anyone sees you,” said the muscular man. He led her inside. “This suddenly seems like a bad idea. I don't know if we should continue.”

“Why?” said Karen. “Nobody is ever going to find out.”

“Well, I guess that's true.” He relaxed a little. “But it's still wrong. I really love my wife.”

Karen walked up close to him and put her arms around his shoulders. “That's okay. We're not in *love* or anything. A little fling is totally acceptable as long as it's just about the sex.”

“Yeah. Yeah, I guess you're right,” said Tony, visibly relaxing. He looked down at the hot redhead in front of him and put his arms around her. He leaned down and kissed her deeply. The two pushed against each other as the kiss deepened. Karen could feel his very large erection through his shorts.

When they broke the kiss, Karen said, “If you're still nervous, there's one thing that always helps you relax.”
