An Unexpected Betrayal

I had just turned nineteen when I saw my stepmother topless, and I was instantly obsessed with large breasts.

Paula, my fathers second wife, was oblivious to my presence as she walked past my bedroom door, her amazing uncovered boobs swinging freely. The only modicum of decency was the bath towel wrapped around her waist, coupled with a smaller head towel tied around her long black hair.

The glimpse I had was fleeting, but, it sparked into life a flame of desire that had never diminished. Over the following years I had manufactured ways to see more of Paula in states of undress and I had been pretty succesful in my tasks.

When I started dating Nicola she was almost a carbon copy of my stepmom, her curves an instant attraction. Our sex life was at first tentative but as our confidence with each other grew, so did our experimentation. No stones were left unturned as we tried pretty much everything we could, porn a constant source of inspiration.

Even after we were married and became parents our sex was always intense and fun, however as we moved into our fifties, still madly in love, it did start to slow down considerably.

I was proud of the fact that I'd never strayed, the chances had arisen at times, and as far as I was aware, Nicola had never cheated either, so when the following scenario happened I was genuinely shocked and felt very guilty.

My day had begun like any other normal day. A large breakfast followed by a leisurely stroll through the local countryside. I had travelled about four miles when the need to pee became evident and I moved off the trail to empty my bladder.

Mid-stream I heard footsteps approaching from the rear. As I turned, trying desperately not to urinate on my boots, I saw a very slim female heading towards me. I guessed her age to be early twenties and noticed that although very pretty, she had no curves at all. The baseball cap on her head giving her the appearance of a young boy.

"Erm, hello" I said making sure my member was out of view to my unexpected guest.

The woman stepped closer without speaking. She dropped to her knees and grabbed my hips, turning me towards her. I watched in shock as the last few drops from my bladder splashed onto the blue shirt she was wearing. My jeans button was expertly dispatched and without hesitation her tongue began to lick my tip. I knew deep down I should stop her but it felt amazing. Her skills with her mouth were exquisite as she greedily took my hardening rod into the back of her throat. Nicola gave great head. This stranger was better. I roughly grabbed her head and drove deeper into her throat, her tongue running underneath my shaft as she gagged noisily.

As I felt an orgasm approaching, I lifted her to her feet and span her round. The pink cotton shorts she had on were no match for my intense need to be inside her and the fact she was soaking wet meant entry was instant. With an unrelenting force I rammed my hardness into her private slit, her muscles contracting around me as our rhythm matched. I felt her hand cupping my balls as I lost any trace of guilt. The speed of my thrusts increased as the primal need for release pushed me close to the edge. A small whimper escaped from this strange woman as her own orgasm tore through her body, her small behind trembling as my onslaught continued. As the passion between us intensified I momentarily thought of my wife and I thought about stopping this carnal escapade but in all honesty the betrayal was already real and my hardness didn't seem to care about my marriage.

When I finally erupted inside her the amount of my life seed was incomparable to anything I'd delivered before. I stepped back speechless and watched as my spunk slowly oozed out of her hole, the swollen pink pussy lips inflamed with passion.

The shorts were raised and a small smile crossed her face before she moved off back in the direction she had come from.

It took me several minutes to regain my composure as I marvelled at what had just happened. Not only had I cheated on my soul partner but it had been with a woman that I would never have looked at normally.

I headed back to the trail wondering who this mysterious woman was. I guess I will never know...
