When Heather had left the room, Kayla Grant sniffed the paddle. It certainly carried the musky smell of recent sex. She wiped it down and put it back in her cabinet. She could not be too judgmental about Heather getting a little lunchtime nooky, as she herself sometimes indulged in similar extra-curricular pursuits. The afternoon was a busy one but she still found a few smidgens of time to daydream about that paddle being applied to her own bare bottom.

At the end of the day, Heather locked up and returned to Dr Grants office with a tray. “Almost forgot that was today,” Kayla noted. She rose from her desk, hiked up her skirt, pulled down her panties and bend forward over her desk. Heather swabbed her boss’s left cheek and delivered a shot of B-12. She repeated the prep on the right side and quickly pumped a generous dose of vitamin C into Kayla’s round butt cheek. When she was finished she dropped her scrub bottoms and waited for her own shots. She winced slightly as Kayla quickly forced each bolus of serum into her tush. Now the tops of her ass cheeks burned as companions to the still sore lower regions that had been bruised earlier by the paddle.

As Kayla administered the shots to Heather, she glanced down to appreciate the visual results of her work. Each of Heather’s cheeks now sported a prominent bullseye bruise, something that was intensely arousing to Kayla particularly in anticipation of the similar paddling she was due very soon. She walked Heather to the back door of the clinic and locked the door after her. She paused a full minute and then unlocked the door again. She returned to her office to catch-up on notes and was busy for several minutes before she heard the door was opened and then locked again.

A few moments later, Luke appeared in her doorway. “She sat in her car forever,” he explained. He closed the door and then crossed the room to extract the paddle. “You’ve been a naughty girl,” he mock-scolded. The upcoming spanking was more to get then ready for the next act than actual punishment.

“I have indeed,” Kayla admitted. She came around her desk and adopted the position Heather had assumed earlier in the day. Luke tapped the paddle on her round cheeks and gave them a solid swat. Uninhibited that they would be overheard, Kayla cried out loudly, “One!” Her ass was on fire when she shrieked, “Twenty!” and then felt Luke enter her. The collision of his pelvis against her raw bottom was almost like more spanking and soon she arched her back as the electric waves of climax washed over her. Almost simultaneously she felt Luke withdraw and then the warm jets of cum land on her seared bottom. They had collapsed on the couch both still bare below the waist, their respective juices mingling and catching their breath when Kayla heard movement in hallway. “You locked the doors, right?” she whispered to Luke.

He nodded and whispered back, “Both.”

“Heather, is that you?” Kayla called.

Heather had seen Luke waiting and toyed with him, checking email on her phone and taking longer than usual to depart. After she rolled out, she slowly circled the block and returned to see he had left his car. She quietly re-entered the clinic just in time to hear Kayla yell out, ‘Fifteen!’ She listened to the rest of the paddling and then tip-toed back to her desk to grab a charging cable she usually left at work. At least this way, she had a somewhat valid excuse for returning. Passing by the door she now heard the unmistakable sounds of ardent fornication. She smiled at the memories of getting pounded herself just a few hours earlier in the backseat of Pete’s truck. She heard the groans she presumed from respective orgasms and then quiet. She turned to quietly leave and fumbled the cable. During the workday such a sound would be lost but in the post-coitus quiet, it seemed like a cannon-shot. She heard Kayla call. “Yeah. It’s just me. I forgot my charging cable and came back to get it.” She paused and thought perhaps she heard muffled whispering and movement from inside. “I’m heading out now. Have a great weekend.” Heather smiled broadly knowing Kayla’s weekend was already off to a great start. She paused, loitering longer to see what other action might ensue but then thought better of it. On the way out she made sure that closing and locking the door were overtly audible. She sat in her car for a minute thinking about the day. She looked the time and cursed softly. She was now late to her appointed reprise with Pete. He was due for a lengthy hairbrush spanking over her knee and maybe another game of ‘hide-the-snake’ afterwards.
