I hadn't always been the way I'm going to describe. Not long ago, I was a normal, married woman who had sex with her husband twice a week. Sometimes more, sometimes less. We have used sex toys and x-rated movies along with the normal roleplaying that comes with a healthy relationship to give ourselves that needed push when things became stale, as they do in pretty much any marriage.

Things were rolling right along when a past fantasy of my husband's resurfaced. It came up every so often but was usually short-lived since I wasn't the kind of girl who thought about having sex with other men, but I indulged him since it was just a fantasy… At first.

For some reason, this time was different. This time, I was the one who kept the fantasy going. For weeks, the thought of another man touching me fed my desires to the point where my insatiability intensified as time went on. Sex was no longer a simple desire; it had become a vital need, leading to my husband's suggestion that I take a lover.

When he finally persuaded me of his sincerity, I seized the extraordinary opportunity.

I struck up a conversation with a man named Mark while we were searching. He had mentioned to me that, as much as he loved receiving head, he had never been able to orgasm from oral sex. His words intrigued me because I had never enjoyed swallowing cum, at least until my libido went into overdrive. To say that my husband's enthusiasm for my newly developed oral skills was totally unexpected would be a huge understatement, as I had only recently begun swallowing him.

For safety reasons and because my husband truly wished to see me acting naughty, we decided to meet Mark at our favorite sports bar so we could talk and flirt in person. After a while, we ended up sitting in the back seat of my husband's truck. Well, sitting isn't quite right. After a hot and equally passionate makeout session where our tongues mingled and dueled, Mark was leaning against the back seat with his pants half off and my head in his lap bobbing up and down, confirming that we did, in fact, click.

Hubby sat in front while I felt like a giddy teenage girl as I felt Mark swelling in my mouth. My saliva allowed his cock to smoothly move through my lips as my tongue massaged and flicked the head of his cock. He had worked my blouse open and was skillfully massaging my full breasts and puffy areolas surrounding my erect nipples, which were always very responsive, especially when deeply aroused, as I currently found myself.

I was sexually overstimulated and practically shaking in aroused euphoria as I licked, kissed, and sucked my first extramarital cock. Just the feel of another man's heated flesh as my fingers closed around his hard shaft made me almost hyperventilate. As I stroked him, I was mesmerized at how different his cock was from my own husband's, who I had been completely faithful to until now.

I kept looking into the mirror to see if hubby's eyes, which watched every move, showed any signs of regret, but lust was all I could see, which encouraged me further.

Mark reminded me that he didn't cum with oral, undoubtedly so I wouldn't become discouraged in my efforts. Smiling internally at his assertion, I made sure his cock was wet before taking my pointer finger and my thumb and wrapping them under the crown of the head. My husband calls it the grip of death. Instead of going quicker like most guys expect, I slowed my motion so every nerve received the full pleasure that my mouth was giving him.

My desire intensified with each groan from his lips as his cock became more engorged. "Your mouth feels phenomenal," he said as I rotated my head in one direction while my hand twisted the opposite.

As the unexpected sensation of my oral skills became more intense, Mark detached his hands from my hair. His legs clenched and twitched uncontrollably as he made some incoherent noises. Something about hell and Christ and some other words that I had never heard before in a language that he didn't speak.

Suddenly, his balls contracted as his cum was forced through his cock, shooting violently into my eager mouth. Mark tried desperately to regain control while multiple streams coated my tongue. So much was released that I was getting nervous about spilling his precious sperm.

When his orgasm subsided, I pulled off, making sure that none of his treasured cum escaped. Looking at me in astonishment, his eyes widened as I gulped without hesitation, forcing his seed down my throat. 

My husband, who I had almost forgotten was watching the whole thing, asked, "Are you okay back there?"

Mark, still breathing hard and trying to catch his breath, exclaimed, "Holy hell, she swallowed my soul."

With a proud smile on my face and a twinkle in my eye, I squeezed Mark's cock, which was beginning to already harden again, and told him, "I need this inside of me," and asked, "How about we continue this; your bed or mine?"
