Rebecca and her husband

I took a quick look as they walked into the living room. For a minute, I thought they were going to come and talk with me. Instead, they walked as quietly as they could to the back door. I pretended to be asleep so they wouldn't think I was being disturbed. As soon as they exited the house, I got up and walked to the back door.

I saw them disrobing each other as they were kissing. Great, I thought, they were going to have sex again. This time it was either going to be in the pool or on one of the chairs.

My cock stirred as I watched Rebecca give her husband a blowjob. I quickly lowered my shorts, not caring if anybody could see me. I started stroking my cock as I watched Rebecca continue to suck on Chris's cock.

I continued to watch as Chris sat on the chair, bringing Rebecca onto his lap. She lowered herself onto his cock and began riding him. I closed my eyes with pleasure, imagining that Rebecca was riding my cock.

I was so entranced by the show that I didn't hear anybody approach.

"Well, well, what do we have here?"
