Note: This is the shortest story I've ever been able to write so it's not a normal long winded full piece but I like it and wanted to share it.
I hope you enjoy reading as much as enjoyed writing.

Linda was zoned out as she ran naked on the treadmill, her mind into the music from her headphones and the endorphins coursing through her body. She loved the feel of her long legs moving back and forth working her hips. The working of her hips made the slippery lips of her pussy rub together so sensuously. She had had an orgasm in the middle of her first marathon years ago and smiled at the thought.
She could feel her breasts sliding back and forth on her chest as she worked her arms. The perspiration under them made it a silky satiny feeling that made her nipples hard enough to hurt. She shifted her shoulders more and felt them slid even more.
Her body felt so good when she was in the zone. It was a well-oiled machine that felt like it could run forever with the long distance runner's stride she was in. Her lungs expanded and contracted rhythmically causing her chest to expand and contract. This varied the rubbing sensation of her breasts deliciously.
A hard solid slap on her left ass cheek caused her to jump and lose her stride. She grabbed the hand rails to keep from falling as a solid slap landed on her right ass cheek with a burning sting. She looked around to she her husband James grinning at her. She frowned at him and the hand landed on her ass even harder. She gasped at the force of the blow and tried to get back in stride as several more slaps spanked her hard, tight ass cheeks.
