My wife goes to the gym every morning. I love watching her leave the house in her tight lycra leggings and crop top, knowing full well the guys down there will be watching her work out and having a good perv at her. She's 45 but in great shape.
She told me recently that one of the instructors has been flirting with her, and broken the gym's strict "hands off" policy by holding her hips as she lifts weights.
She admitted to fantasising about him, and fucking him early before the rest of the class arrives. Apparently he's some kind of ripped ex military work out adonis. Told her I'd love it if things progressed.
