"TURNABOUT IN TRIPLICATE" by the Crimson Kid [Category: Not My Kink]

penthouse in uptown Manhatten.)

 "Grandma always suspected you were abusive to us," Krystal Kelly
 remarked.
 "I was just strict," Uncle Colm countered, "You needed discipline."
 "We needed 'our bottoms tended to,' wasn't that the expression?"
 Kathleen asked rhetorically.

 "You did," he agreed, addressing the three redheaded 20-year-old
 triplets, sitting side-by-side on the divan.
 "From the time we were toddlers until two years ago," Kiki recalled,
 "We got spanked regularly on our bare fannies, severely for our ages."
 "At least three times a week," Kathleen specified. "Stappings,
 paddlings and hairbrush wallopings as teenagers--our poor rumps blazed
 like hellfire."
 "It was necessary," their uncle muttered. 

 "Was it," demanded Krystal, "Or were you jealous of our trust fund,
 angry about sharing Grandma's wealth, and taking it out on our
 behinds?"
 "Grandma might think so," Kathleen mused, "She'd likely cut our dear
 uncle out of his inheritance altogether."
 "Especially after seeing the photos we took of each other's ravaged
 rears over the years," Krystal added.
 "Ph-Photographs?" Colm gulped. 

 "Million-dollar pictures to you." Krystal licked her lips. 
 "Maybe million-spank ones instead," Kathleen chortled, "Your choice." 
 "What do you mean?" He shuddered. 

 The young women rose together, looking quite intimidating as all were
 six-feet-tall collegiate athletes--Krystal a gymnast, Kathleen a
 swimmer, Kiki a tennis star--with smoothly-toned bodies.
 "We have a proposal," Kiki replied. "You'll need Sunday, Tuesday and
 Thursday nights free for the foreseeable future."
 Colm paled. "For what?" 
 Krystal patted his face. "To 'tend to our bottoms' differently, while
 we repay the 'tending' you've already given them."
  
 "You were cruel to our derrieres, so you'll make sweet apologies."
 Kathleen giggled.
 "I don't understand..." the 50-year-old whined. 
 "Strip to the buff, like you always made us when it was
 'bottom-tending' time," Krystal ordered.
 "...Or Grandma sees our blistered-butt photos," Kiki threatened. 
  
 "We'll move the ottomans, you get the implements, Krys," Kathleen
 instructed.
 "Please..." Colm whimpered.
 "Cry later, undress now," Kathleen commanded. "Hesitation means extra
 punishment, remember?"

 Moments later, Colm was bent naked over a padded ottoman with
 Kathleen astride his back, both them facing Krystal's posterior while
 she was draped, panties down, over an identical stool; the man's face
 nestled between his niece's opulent asscheeks, while Kathleen pushed
 his head forward.
 "You'll be giving Krystal's bottom some long, loving licking," she
 explained.
 While I administer a really good licking on your bare fanny." In a
 forehand stance to her uncle's left, gripping a wooden Spencer paddle,
 Kiki snickered. "Different type of licking, the red-hot stinging kind."

 Krystal wiggled her hips, pushing her bumcheeks against Colm's face.
 "I'll tell you when to stop, both of you--until then keep the lickings
 going."
 "My pleasure." Kiki raised the paddle. 
 "Then we'll switch, positions and implements." Kathleen regarded the
 flat-backed hairbrush and razor strap on the divan. "Uncle Colm will
 'tend to' all of our bottoms."
 Kiki laughed. "And boy, will we ever 'tend to' his, IN SPADES!" 
 She swung the paddle expertly, smacking his naked buttocks
 forcefully, driving his mouth into Krystal's buttcrack.

 Sobbing, Colm flicked his tongue... 
 {The End} 

[Note: The F/M spanking IS my kink, of course, but the much younger
female spankers and the *derriere deifying* aren't necessarily--however,
it all sounds like fun in this context.]
