I love my husband, Eric, but I am a highly sexed woman who finds it very difficult to say 'No' to interesting propositions. Eric knows this, but at least during the early years of our relationship he was more than able to keep me well satisfied. He has a kinky side too, and loves to see me in high heels and short skirts. He guards me possessively in public, while enjoying the way I'm ogled by others, and by the way it makes me so horny I'll do anything for him.
He loves fucking me in public places. There are a handful of dogging sites we visit regularly, where people watch from outside the car as I strip off inside, suck his cock, and then ride him to orgasm. But his favourite thing is to fuck me in stairwells, out of sight of cameras but with the risk that someone will appear at any moment. A horrified gasp from an unwitting stranger, and their hurried retreat, is usually enough to make him come - though there have been occasions when the strangers have walked past us, laughing and cheering us on.
A few months ago, pressed against each other in a train on the way to a football match, surrounded by fans who were shouting loudly at each other, he took me from behind. He fucked me slowly at first, trying not to be obvious, but our coupling did not go unnoticed. Or ignored. The man in front of me grabbed my breasts through my top and teased my nipples, and I reached down to unzip his jeans and free his semi-erect cock.
The train was so packed that although Eric could see this stranger handling my tits, he couldn't see me stroking the increasingly hard cock below. Having my husband's thick cock slowly pumping away at me amidst this small audience of hungry gazes should have been enough for me, but no way was I letting go of the long, smooth shaft that felt so good in my hand.
My husband eased out of me at last, having filled me with his warm, creamy cum, and I turned and kissed him passionately, distracting him for a minute as the hard cock slipped into me from behind and worked me with long, deep, steady thrusts. If the man's beautifully pulsing length hadn't triggered my own too obvious orgasm, I might even have got away with it.
The football match proved to be rather tense. Eric scowled the whole way through and I didn't dare say anything as my knickers became increasingly soaked with my husband's cum as well as that of another man. That our team won may have lightened his mood, however, since on the way home he seemed pensive rather than angry.
"Take your knickers off," he instructed firmly as we waited for the train to take us home. "Throw them on the track."
Reluctantly I did as ordered. A girl in a short skirt taking off her knickers and throwing them where everyone could see what they were... did not go unnoticed. I felt like there were a hundred eyes on me. Certainly the cock that pressed against my cheeks once we finally crowded onto the train was not Eric's. He was watching from the side as someone I couldn't see clearly pushed his hard length against my soaking pussy and thrust into me.
There were hands all over me, squeezing my breasts, pulling on my nipples, rubbing my clit, fingering my ass, and Eric watched it all with a blank expression. I couldn't tell whether he was enjoying what was happening to me. The man behind me certainly enjoyed himself, pounding into me with fury until I felt him stiffen and unload.
As soon as he pulled out, another took his place, and there was just time for a third to reach his conclusion before we pulled into the main station and the train emptied.
I could barely stand. I was tense with need for the climax that had eluded me, but also exhausted from the events of the afternoon. The cum of three strangers, and perhaps still the fourth, was leaking from my pussy and making my thighs wet and sticky. My relief that Eric stayed with me, and supported me as we walked to the car, was profound, and I dared to hope that he had forgiven me, and perhaps that he had enjoyed giving me to other men.
In the stairwell of the multi-storey, he gave me the spanking that I surely deserved, and then fucked me with a rough urgency that finally took me to the edge and beyond. I howled with pleasure, uncaring of any listeners, my orgasm only intensified by the welcome sensation of my husband's own satisfaction.

He sat me down for a talk that evening, having gone out somewhere without explanation while I dozed in a warm bath. He still didn't seem angry with me, but he certainly looked serious. "I knew you were a slut, even before we married, but I never realised how out of control you were."
"I'm sorry," I said. "I really can't help it."
Eric nodded. "I know. I'm not angry, but I can't go through life wondering who else is taking advantage of your horny cunt." His choice of words made me blush furiously. I could feel my cheeks burn. How odd that being fucked by a series of strangers was less embarrassing than having a 'horny cunt'.
He continued. "So, you have a choice. Either we get a divorce, and maybe you can find a man more accepting of your infidelity, or..." He pulled from a bag a studded leather something, some kind of thong maybe.
I took it from him and inspected it, and comprehension dawned. "A chastity belt?"
"Yes."
"For how long?"
"As long as we're married."
The thought of wearing something so ugly and so confining, and of surrendering control of the most intimate part of me - that I had surrendered to four complete strangers in one day - was difficult to get my head around.
But divorcing Eric? I loved him. It would break my heart to leave him.
