If you have been reading the blog then you will know I wrote a post called Joint Spanking a few weeks back. The inspiration for that post and my desire, still unfilled, to be spanked with my partner comes from this story I found on the web years ago. I hope you enjoy reading it as much as I did when I first came across it. 
Aunt Mary 
My wife Sara and I play spanking games. We take turns spanking and  getting spanked and after a spanking, or sometimes a pair of spankings  (one for each of us) we always make love. I think I enjoy the spanking  play more than my wife does.
She plays though, and sometimes she is the one who suggests a spanking.  When it is her idea, I am usually the one who gets the spanking. Our  spankings are not very painful. I spank her with my hand. She spanks me  with a paddle, because I can hardly feel her hand spankings. When she  uses the paddle the spanking stings, but just enough to be exciting.
That has been fun, but last weekend we had an experience that was the most intense and exciting I have ever experienced.
Sara's friend Mary was visiting us for a few days. Mary lives out of  state, but was in town on business. Of course, Sara insisted that Mary  stay with us. Sara and I both enjoyed having her there. It is more fun  to enjoy your home town, when you have an out of towner to show around.
During dinner Friday night, Mary mentioned that she was going to buy a  copy of Secretary. "It is an independent film from last summer that got a  lot of attention at the Sundance film festival. Did you guys see it"
"Yes" I said "Sara and I saw it last summer. I thought it was really well done. Funny and kind of sweet"
"I agree" Mary looked at my wife I thought the spankings were kind of  sexy too, Do you and Robert ever of think about spanking each other"
I could tell my wife was a little embarrassed, but Mary had already said  it was sexy and Sara wouldn't mislead her good friend. Sara didn't  provide any details, but she smiled and "fessed up" to how we give each  other "love taps" from time to time.
Mary turned to me and asked "Just a little slap on the hiney, or is it  over the knee or grab your ankles stuff?" I explained that we weren't  abusive, but that sometimes we did a bit more than just a slap on the  hiney. Mary seemed kind of impressed, but let the conversation drift to  other things. I was a little relieved to be off of the subject as Sara  and I had never discussed our spanking games with any one.
Although we enjoyed having Mary visiting, a house guest did add stress.  By Saturday night Sara and I felt like snapping at each other. We were  trying to keep it private, so while Mary was showering we exchanged some  sharp words. Of course, we quit paying attention to our surroundings  and were still picking at each other when Mary came into the kitchen.
"What is this?" She asked "Are you two having a spat?"
"Oh it's nothing" Sara answered "He just gets like this sometimes"
"Well, I heard childish bickering from both of you. You both deserve a  spanking. This is my last night here, so I am going to take this  opportunity to give it to you"
I saw Mary's smile and guessed she was joking. "We deserve one, but I  don't think you are really serious" I said, and met her smile with a  smile of my own.
"Sara, what do you think?" Mary asked. Sara, unusually quiet, just shrugged.
"Ok then, you will see what serious is Robert. You two go up to your  bedroom, remove your slacks and wait for me." Sara and I had been  sniping at each other just minutes ago, but now Sara took my hand,  squeezed it, and walked upstairs with me.
I couldn't believe anything was really happening. After I entered the  bedroom, I stalled for a moment to see what Sara would do. To my  surprise, she removed her heels and began to pull down her navy blue  slacks.
I was starting to get a funny feeling in my stomach. This was something  new, exciting and scary all at the same time. I took off my loafers,  slipped out of my trousers, hung them over a chair and set next to my  wife on the bed. I had those "principal's office" butterflies in my  stomach. I asked Sara, in a hoarse whisper if Mary would really spank  us.
"I don't know"
"If Mary wants to, will you let her"
Sara took my hand. "I will if you will" she said.
Mary walked in still wearing her beige skirt and jacket with a white  blouse. Sara and I were sitting knee to bare knee, holding hands, fully  dressed from the waist up, but just underwear from the waist down.
"You seem to be behaving yourselves now, why do you suppose that is?" Sara just shrugged. I didn't know what to say.
"Well Robert, get the paddle." There was no way Mary could have known  that we had a paddle, and I was embarrassed about walking to the  nightstand to get it. I was in my underwear for one thing, but was most  embarrassed by the erection that clearly tented out my thin underwear.  Nevertheless, I obeyed. I walked quickly to the nightstand and pulled  out my home made paddle.
Mary took it, patted her palm and said "nice". I am pleased with my  paddle. I had re-sawn a piece of oak to make a 3/8" board 20" long by 3  ½" wide. I had cut out a comfortable handle, rounded all of the edges,  sanded and finished it with rubbing oil.
"Now then", Mary said. "Each of you go to your side of the bed and bend over it to receive your spanking."
I went to the right side of the bed, while Sara went to the left. Our  bed is high enough so that my knees were just touching the floor and I  knew that Sara's knees would not quite touch the floor. Mary walked  behind Sara, bent over, and pulled down Sara's panties. I could see the  surprise on Sara's face.
I was looking across the bed into Sara's face and could see past Sara to  what Mary was doing. Sara could see my face, but she couldn't see what  Mary was doing.
What Mary was doing was moving behind and to left of Sara's bare bottom.  Mary removed her jacket and unbuttoned her cuffs. Mary stood at a right  angle to Sara's buttocks, lifted the paddle to shoulder height and  brought it down HARD on Sara's butt. Sara gasped. I did too. I saw  Sara's mouth make a little O of surprise and her eyes widened with the  shock and pain. Sara had never been spanked with a paddle, just by my  hand. Before Sara hardly knew what had happened, (maybe she thought it  was over) Mary had the paddle shoulder high again and slammed it down  onto Sara's defenseless bottom a second time. This time I saw Sara  wince. Her eyes squinted shut, her lips separated to show teeth, and her  hands flew back to cover her sore posterior.
"Sara", Mary scolded. "You are NOT to cover your naughty ass with your  hands. What if I hit your hand by mistake. If you don't want me to  finish, I will stop this spanking now and go back to my room. Do you  want me to stop" Nothing has ever surprised me more than my wife's  answer. She muttered that she didn't want Mary to quit. It put a lump in  my throat. I didn't know if Sara was sharing my fantasy now come true,  or if she just wanted to make sure the spanking didn't end without me  getting my punishment share.
Mary made sure that Sara was willing. "Sara, you will answer me again  and you will address me as Aunt Mary" I hadn't thought of Mary as Sara's  aunt, but actually she is. Sara and Mary were almost the same age, but  Mary was the youngest daughter of Sara's grandmother.
"Please don't stop the spanking Aunt Mary"
"Fine, you may reach across and hold Robert's hands so that you don't  cover up again. That lapse is going to cost you an extra stroke." With  that, Mary's hand went up again and SPLAT the paddle came down on Sara's  upturned bottom. Sara squeezed my hands in hers but didn't move.
"Very good, here comes the penalty stroke and then I will go to Robert"  She raised the paddle higher than before and brought down the hardest  swat so far. Sara cried out and winced but didn't let go of my hand. I  felt love and pity for my darling. Her face was puffy and red and there  was a trickle of a tear at the corner of her eye.
My feeling for Sara didn't lessen the concern for myself though. I knew  that this spanking was going to hurt. I was determined to take my three  swats without covering myself and without shaming myself in front of  Sara.
Mary walked behind me and pulled my underwear down. I felt shy and  defenseless without my shorts between Mary and myself. Mary took  position behind me. I was cheating. I could watch Mary's preparation.  There is a dressing mirror in the corner of the room and unnoticed by  Mary or Sara I used that mirror to watch Mary raise the paddle to above  shoulder height, AND bend from the knees AND twist at the waist. She had  put the full strength of her shoulder and arm into Sara's spanking. She  was adding the weight and strength of her legs and torso into my  spanking.
WHAM, the paddle hit my bare butt harder than I could have imagined. I  grunted/gasped and looked across at Sara. Her red face and wet eyes were  right in front of me. She held out her hands and I grasped them.
"Do you think you should hold Sara's hand to avoid covering up"
"Yes Maam", I replied. She wasn't my aunt, and my response satisfied  her. She blasted my bottom again with a second swat. I squeezed my  wife's hand so hard I might have hurt her, but she didn't complain. I  took a deep breath just in time to expel it with the third swat. I would  have liked to reach back and rub my bottom, but I didn't know if Mary  would approve. In addition, I was too proud to show how much it hurt. It  burnt like fire. I was glad I had taken my three, but I was a tiny bit  disappointed that it was over.
It wasn't though. Mary walked around the bed to Sara again. Without  letting Sara know what was happening (poor Sara, not able to see what  was coming) she gave Sara another swat. "Ohhh" Sara gasped and grabbed  my hands. Another blow came down and Sara started twisting on the bed.  By the time the third spank hit Sara's round bottom she was whimpering  and tears flooded her eyes.
I was so proud of her. She was holding my hands. I wasn't holding hers.  At any time, she could have just stood up and said stop it. Soon Mary  was back in position behind me. Obviously, it wasn't just three hard  blows, but an unknown number of sets of three that we were getting.
Before Mary had completely walked around I had reversed my grip to hold  Sara's hand. POW, the paddle hit my already sore butt with all the force  that the athletic woman could put into it. I couldn't help making  noise. Before I was prepared, the second SPLAT hit the soft part of my  bottom right above the thighs. I confess that I cried out, closed my  eyes tight, and held my wife's hand as hard as I could. When the third  blow landed I couldn't hold still. I had enough control to keep my hands  still, but I arched my back and kicked my feet a little.
That had to be it. I felt I could not handle another set. Consequently,  when I saw Mary move back behind Sara for the third set I almost begged  her to stop. I kept my teeth clenched though, and I think Sara could  tell what to expect from my face. She grabbed my hands, put her face  down in the bedspread and waited - bottom up. She didn't wait long. That  incredibly loud smack hit just an instant before Sara twitched and  wrung my hands. Two more SPLAT SPLAT landed on Sara's hind end and by  this time Sara was crying and sniffling out loud but still not asking  Mary to stop.
It was my turn again. I don't think I would have stayed in place if not  for Sara. Sara had never experienced anything more intense than a hand  spanking and she was taking this paddling. I had to too. By the second  swat I was squirming. In fact, my back was arched, by butt was clenched  and pressed into the side of the bed. I felt like a little boy trying to  keep his little bottom far away from a spanking hand that inexorably  follows his arching twisting attempt to move his bottom away.
By the third swat I was in tears. I don't think I made sobbing noises  but I couldn't control my tear ducts. I couldn't believe it, when Mary  walked around the bed again and took her place behind Sara. This had to  stop. I was about to say enough when Mary spoke.
"Sara, have you learned your lesson"
"Yesss, Aunt Mary" she sobbed.
"Very well, your spanking will be over with one more swat, IF you ask for it 
nicely"
"Please Aunt Mary, will you please give me one last spank" (I  appreciated how Sara asked nicely AND got the ONE LAST spank part into  the contract)
"Are you sure?"
"Yes Aunt Mary"
Mary wound up like she had for my spankings and let Sara have it. The  hardest one Sara had felt yet. "OWWW", Sara shouted in pain but kept her  hands on mine.
Now Mary came back around to my side of the bed. One more, I had to do it. 
Sara had.
"Same deal for you Robert, have you learned your lesson"
I took a deep breath to acquire control over my voice "Yes Ma'am I have  learned my lesson, but please Ma'am give me one last spank to make sure"  Mary chuckled. I could see her in the mirror, but I couldn't stand to  watch.
I closed my eyes. It seemed like I waited and waited. I was just about  to lose my nerve when POW the last swat hit my blistered buns. My eyes  watered so much that everything blurred, but I held my position.
Mary leaned over and kissed my cheek. "I want you to two to get up and  go to bed after I leave. You have been wonderful hosts. Sleep in  tomorrow morning, I will cook you breakfast. Be good to each other" On  her way out she stopped and kissed Sara's cheek.
When Mary left, Sara and I finished undressing and slid under the  bedspread. I reached over and touched Sara's damp cheek. "You were so  brave, I love you so much"
"I love you too. Mary hit you so HARD, I don't know how you could stand it."
I reached across and caressed Sara's right buttock. It was hot to the touch.
I asked her if her bottom was on fire like mine. She giggled and asked me if 
she could touch mine.
"OOOH, it is so HOT she giggled" I put my mouth on her nipple, gently  rubbed her hot ass, and then kissed her lips. In return she lightly  touched my sore butt and touched me in other places I liked. Her  attention to my well-punished ass was deliciously erotic.
Soon, she was lowering herself on my blue steel erection. (I was a  gentleman and suggesting she be on top). The smooth sheets irritated my  sore buns. She was hot and tight and slippery as warm oil, I reached  around her to caress her hot hind end and we slowly made love.
