My jaw dropped when I opened the door.

The ex-girlfriend was standing in front of me, smiling, waving what looked like a table tennis bat in her hands.

"Come on," she said, "for old times' sake."

I shook my head, "I don't think so," I added.

Uncertainty took a hold on me. Biting her lower lip always had that effect as she slowly moved her head. "But, you're the best, especially when you slide your cock into my hot and stinging ass afterwards."

She had a point, and I sighed in desperation. She struggled to look around me to see if anyone else was in the house before edging past. She paused on the stairs, lifted her dress until it rested on her waist and held her hand behind her back so I could take the paddle.

I looked at her plump ass, presented to me like it was a gift from heaven. She never turned to look at me, because if she had I may well have told her to leave, but seeing her naked from the waist down, and with my gaze firmly on the paddle, well, what could I do?

I melted. I took the paddle from her hands. Her bottom seemed to rise upwards a few inches and I knew from experience she would be close to dripping on the carpet.

I sighed. She had acted like a desperate slut, turning up at the house as she did, almost pleading for me to punish her, anticipation running high and hoping that I'd cave in and spank her bare bottom. I mean, what did she take me for?

It had been a year since we split up. I had remarried and was happy in my relationship, and yet the silence, all by itself was turning me on. Her body never flinched and I must have watched it for over three minutes, waiting for it to move. Her head buried itself in the folds of her arms until...

She cried out and rapidly raised her head upwards, the flesh of her bottom rippling from side to side, an oval red mark spread outwards from the point of contact with the paddle. She immediately replaced her head and waited for the next strike. It was harder than the first. She always liked them to be harder the more she had, though I did alternate the cheeks that the paddle came down on, more for my benefit to see her ass glow red, ready to be poked when it suited me.

She knew how this would play out. She'd been in this situation before, once when she was eating her friend's cunt. Her friend had grabbed her by the ears and pulled her close so that she had no room to manoeuvre, her face and tongue tight to her snatch. The room was full of filthy words, and every time her friend said, "Lick it!" I let the paddle fall. Only when her friend had climaxed did I drop the paddle to fuck her hard.

The sixth strike was hard; the upward force on her bottom nearly pulled her knees off the stairs and there was six more to go. Her cheeks were bright red, and I didn't need to put my hands anywhere near her pussy to know that her juices were flowing. The eighth stroke brought a low moan and the word "fuck" fell from her mouth.

I placed my hand upon the small of her back to keep her still as I administered the last few slaps, pausing after the ninth one, to allow her legs to calm down after the violent shaking as she desperately tried to dissipate the result of successive stings and ate last one orgasm.

In the intervening moments, I undid my trousers and pulled my stiff cock free of its confines. I watched it bounce as the twelfth strike landed on her left cheek, and I heard a subdued sob coming from the direction of her mouth.

She probably didn't hear the clunk of the paddle as it hit the wooden floor, but she certainly felt my stiff cock push against her little star. My hand came down on her backside to remind her of how she was to behave. She took it all and even pushed back towards me to make sure it was all the way in before she started moaning loudly.

The fuck was furious. Her babbling sounds of "I'm cumming, I'm cumming," were lost amongst the slapping of my body against her ass and the pounding that my cock was giving her.

I didn't last of course, mostly because this was so taboo, so naughty, so wrong on so many different levels. I grabbed her hair and snapped it back just before I shot my load into her. Six strokes was all it took to unload everything I had into her. God, how I missed the way she climaxed.

Leaning into her shaking body, I placed my mouth close to her ears. "You can see yourself out," I whispered.

I put my wilting cock back into my trousers, opened the door for her, and headed for the kitchen.

It took all of five minutes for her to get herself together, wipe her smudged mascara from her eyes, and make herself presentable. She poked her head into the kitchen. "I'm just leaving," she said in that breathless tone.

I nodded.

I could feel the heat emanating from her ass as she turned to leave. I could see a wet patch near her backside from where my spunk was leaking out while she sat on the stairs tidying herself up.

"Don't forget to take the paddle," I shouted.

The door slammed shut, and she was gone, just as quickly as she arrived. The wet patch she left on the stairs took ten minutes to dry.

I shook my head. I shouldn't have entertained her bad behaviour, but then, we were always as bad as each other.
