This all began a few weeks ago. I was working from home on a perfect autumn day. The temperatures were still mild and the windows were open. It was late afternoon and daylight was fading as I was shutting down for the day. I heard loud voices from next door. I recognized one voice as Mona, who had moved-in the past summer. We had chatted casually and I knew she was a nurse practitioner and single mom of two college-aged girls - Dawn and Rose. I had seen both young women in passing but really did not know them well or even which was which.

The raised voices seemed to be in response to a dispute but initially the specifics were unclear. I felt a bit guilty at eavesdropping but my curiosity was stronger. I moved closer to the window to hear better. I heard Mona address Rose by name and then express her dissatisfaction at her daughter’s academic commitment. There was more indistinct arguing and then I heard the other voice - presumably Rose’s - loudly declare “I’m too old for a spanking.”

Curiosity now turned into obsession. I expected the argument was occurring in a room diagonal from where I was listening. I could see the room was lit and the blinds were open. I had figured the best vantage point was in the master bathroom when I heard Mona reply, “You’re never too old for a good spanking.” I grabbed a step stool I kept in my home office and hurried to the bathroom.

A narrow window high on the wall provided natural light yet afforded privacy from the outside. One sash slid sideways and was already partially open. I quietly planted the stool and stepped up to peer over the edge. Mona was sitting on the end a bed facing to my right. She was wagging a hairbrush with her right hand, so I assumed the threatened spanking would have Rose facing away from my to provide a spectacular view of her bottom during the spanking. “Dawn!” Mona called. “Get up here. I want you to see this.”

“Mom! No! Please!” Rose begged. Moments later Dawn entered the room. The new arrival had an odd look on her face that I interpreted partly as eagerness to see her older sister punished but a bit worried that even as an adult spankings were definitely still a consequence if her mom was sufficiently motivated. “Rose,” Mona scolded, “Get your jeans and panties down and get over my knee now.” Rose balked. “If you don’t bare your bottom immediately and assume the position, I’m gonna add a good whoopin’ with the belt to you sentence. Rose stomped like a petulant child and slowly unfastened her jeans.

“Hurry up, young lady,” Mona chided. “Dawn, go fetch me the belt!” Rose quickly finished the job and sprawled over her mom’s knee. Mona began to paddle with ferocity. I had a perfect view of the young woman’s very appealing bottom as it turned from pale to pink and also a direct view of her vulva as her legs kicked and splayed. I figured the spanking last just over a minute but it left Rose’s bottom deeply bruised and me terrifically hard. I quickly solved my tension but expected Rose would not be sitting comfortably for a few days to come.

An hour later, I ventured out to the communal mailbox. When I pivoted to return home, Mona was approaching. “Sorry for the noise earlier,” she apologized. “Rose really had a lousy semester and I kinda flipped-out when I saw her grades.”

“No worries,” I replied.

“Anyhow, sorry ‘bout the disruption,” she added.

“I do have one question,” I noted. “Does that adage ‘You’re never too old for a good spanking’ apply to everyone?”

She looked briefly embarrassed but the recovered quickly and retorted, “Try my patience and you’ll find out.”

I winked and returned the banter, “Maybe I will…sounds like fun. And to be clear, the rule also applies to you, right?”

She nodded in affirmation as I imagined her over my knee, her bottom bare and pink in response to my swats.
