I was the last person to leave a co-worker's pool party. He's kind of my trainer. He and his wife are probably close to forty years old and nice people.

After everyone was gone, I was helping to clean up. She brought out more drinks. We settled in and my friend started making sex jokes and comments. For an older woman his wife was pretty good looking. She had short blond hair and big boobs and was pretty open sexually.

While we were sitting there, he started rubbing her crotch through her bathing suit. She started moaning and really got into it. I couldn't see but I was pretty sure he was fingering her cuz of the way she was moaning. When he pulled out her boobs I was hard as a rock. They had some sag to them but they were really nice.

He pulled off her bathing suit and she started sucking his dick. I pulled mine out and started stroking it. She was on her side on a lounge chair, her leg up just enough to expose her pussy to me. I watched her sucking and stared at her pussy while I stroked until I felt my load rising. I wasn't sure what to do so I scooted over to her ass, started rubbing my cock on her pussy lips until I blew my load all over her c**t.

Afterward I sat back and watched her finish him with her mouth. She swallowed when he came. I don't know many girls who do so that was pretty cool. When my friend walked me out he told me I should have fucked her.
