It was twilight on a summer Sunday evening, the weather having been cool enough to turn-off the AC and open the windows. Jane was in her side yard pruning roses when she heard odd rhythmic slapping sounds coming from next door. Her neighbor, Karl, lived alone and while they often chatted casually, she really knew very little about him. It occurred to her that her previous encounter with sounds like this was when she got her first job just out of college and rented a small two bedroom apartment with another recent grad, Stephanie. Stephanie and her boyfriend - whose name Jane could not recall - liked to incorporate spanking into their foreplay. The apartment had paper-thin walls, and Jane got accustomed to the sound of one or both of them getting spanked as a prologue to the noisy cadence of the bed squeaking during fornication.

Jane tried to peer through the hedge that separated the yards but could only see that Karl’ window was open a few inches. Her intrigue about what might be going on inside overcame her usual reserved nature. She squeezed through a gap in the hedge and tip-toed quietly until she was beside the partially open window. Thinking any sudden movements might give her away, she slowly slid sideways until one eye could see into the room. Karl was in the center of what looked like his home office. He was sitting in a chair, facing to Jane’s right as he spanked a very rosy, bare bottom with a hairbrush.

From the size and shape of the tush and other evident landmarks, Jane could see that the recipient was a petite, pale female. The woman’s mop of curly, red hair was evident as her head bobbed up and down as the swats fell. She was wearing what appeared to be a yellow sundress, hiked-up above her hips and her pale pink panties, dangled from one ankle. The hairbrush had given the woman’s cheeks a color comparable to her hair. Despite the odd viewing angle, there was something strangely familiar about the woman getting her ass thoroughly spanked.

Karl paused the spanking for a moment and asked something that Jane could not discern. The woman responded but again Jane could not make-out the words. Karl responded with five hard swats to the right sit spot and another volley to the left. He waited while the woman caught her breath and then she slid off his lap and knelt in front of him. Jane then realized the redhead with the very red ass was her co-worker, Meghan. Jane had already anticipated the next move when Meghan reached up and opened Karl’ pants and freed his erection. She took him in her mouth and quite soon brought him to climax, neatly consuming the byproducts.

Jane quietly snuck back through the hedge and retreated into her own house. Her own bedroom overlooked the street and she gazed through a part in the curtains at the car in front of Karl’ that she assumed was Meghan’s. Soon Meghan appeared, looking a bit furtive as she approached the car before driving away. Jane realized how aroused she was herself and laid down on the bed, replaying the scene in her head while using her trusty vibrator to bring herself to a shattering climax.

Jane had initially become curious about spanking while living with Stephanie. Overhearing noises of spanking and sex in the adjacent bedroom and then Stephanie’s unabashed and detailed narration of their hijinks had spurred inquisitiveness and fantasy. Now after having witnessed the scene with Karl and Meghan, Jane’s intrigue was much intensified. She wanted to know about the backstory of what she had witnessed and how the two had connected. She pondered how she might approach the topic with Meghan, someone she knew only casually. She could not exactly admit to Meghan that she had surreptitiously watched the very intimate event. She wondered how she might obliquely introduce the subject without creating suspicion and hopefully coax Meghan to reveal her naughty secret.
