Brian was my husband's friend since primary school; he was also the best man at our wedding. However, he and I were never close. I think I resented him a little because he had been close to Robbie for so long. Strange then that he should become a regular sex partner for a time in our marriage.

Our sexual adventure began unexpectedly one Saturday on a regular night out in the pub.

In the early days of our marriage, Robbie was notoriously a big drinker, and this caused one or two arguments between us. Nothing too serious, but unfortunately still very upsetting. Wrongly, I blamed Brian for much of this behaviour. He was still unmarried and lived the single lifestyle. Now, of course, I know differently, and that my husband was the problem all along.

On this particular Saturday, Robbie had gone to watch the football, and after the game, he returned to meet me in the pub for a bite of dinner and some drinks. On arrival, it was plain to see my hubby had obviously had a few drinks at the football. Wine and a few drinks were consumed with our meal, and then we moved to another local bar for the live music

In the bar, we sat with our usual group of friends, and yes, Brian was there too. Already by this time, Robbie was pretty drunk. Brian approached me and sat beside me at the table and suggested I should get Robbie home as he was drunk. He was preaching to the converted. Robbie had gone to the bar to get more drinks. Brian and I just chatted generally.

"Look, Louise, I know you don't like me much, but honestly, I think Robbie and you make a great couple. I genuinely want what's best for you both," he said.

I was pleasantly surprised and impressed by this and replied, "Brian, I don't dislike you, but you do have a bad reputation, and I worry about the influence you have on Robbie." I sighed. "Even though you are a bit of a player."

"Is that sexual tension I'm sensing between us, Louise?" He laughed.

"No, Brian, that's just regular tension because you're still a dick," I replied laughingly.

I hadn't noticed, but during our conversation, his hand had moved on to my leg and was resting on my bare thigh above my knee and just below the hem of my skirt. He squeezed my thigh and smiled. I must admit it gave me a bit of a thrill until he withdrew it as Robbie approached with more drinks.

Robbie sat back down at the table with two drinks for himself and one for me. So, imagine my surprise when Brian suggested to him that the three of us get a taxi and return to our flat. Robbie was a bit unsure, hinting he wanted to stay out, then I suggested we could have more drinks at ours, but at least the music would be of our choosing.

Ten minutes later, Brian, Robbie and I were in a taxi heading to our flat, Brian's reasoning being it would be more likely Robbie would fall asleep in his own surroundings, and then he would be able to help me get him to bed.

Once inside our flat, I poured three drinks, making sure Robbie's was mostly filled with Cola and only a dash of vodka as he was already hammered. Robbie had put on some rock music and sat down in his chair. Brian and I were sat on the couch chatting, and within ten minutes, Robbie was drifting off to sleep. I asked him to go to bed, but he was adamant he wanted to stay and party. A further twenty minutes later, Brian and I heard light snores coming from my husband. We both finished our drinks and had a little chuckle before Brian gently woke him.

"Come on, Rab, it's been a great night, now time for bed, buddy," he spoke quietly. "My taxi will be here soon, and I want to see you settled before I go."

"Ok, man, give me a hand to my bed, and you can fuck off," Robbie slurred.

Brian and I managed to get him into our room, and as I started to get him undressed for bed Brian returned to the lounge to call his taxi.

I returned ten minutes later, and Brian informed me that there were no taxis available for two hours and that he would just walk home. I told him not to be silly and to pour us two drinks. He poured two vodkas and joined me sitting on the couch.

We sat chatting about our lives in general, then I asked him about some of the things Robbie had told me about them when they were younger. He proceeded to tell me about holiday trips and football trips abroad. However, he never revealed any of their sexual exploits. So, I asked why he didn't have a steady girlfriend.

"I enjoy sex too much, the thrill of having a different woman to feel. If I had a regular girlfriend, sex might get boring and stale."

I was quite hurt by this and replied, "So. you think I would be a dull and boring fuck, do you?"

"God no, Louise. Rab says you're a fantastic ride. You"re up for it all the time, even roleplay and fantasy sex," he announced.

"Oh, he told you that, did he? Did he also tell you that sometimes I fantasize it's you fucking me when it's him?" I replied, smiling.

"No, he didn't," Brian replied before adding, "I'd love to fuck you, Louise. Would you be up for that?"

I gently placed my hand on his groin and began to slide his zip down to free his erect cock.

"Does this answer your question?" I whispered, turning to face him.

He was staring straight at me as I leaned forward and kissed him on the lips, gently stroking his erect cock.

"Fuck, Louise, you are a horny cunt. Rab was right. Spread those legs, you sexy bitch," he panted.

I lay back on the couch and spread my legs. He dropped to his knees before me and pushed my skirt up to reveal my black silk panties. He eased them to the side and inserted his middle finger into my wet pussy.

"Let's see those big tits of yours, Louise. I've dreamt about sucking on them for ages," he ordered. As Brian fingered my pussy, I unbuttoned my blouse and dropped it on the floor. I then popped out both my breasts from my black bra and started to play with them.

"Brian, baby, get that tongue in my fanny. I want you to eat my fanny," I purred.

As I lay back, fondling my tits, Brian eased my panties down and off, then slid his tongue deep into my pussy. He was licking, lapping, and probing at my pussy as I lay with my eyes closed, moaning in pleasure.

"Oh, yes, baby, work my clitty, babes," I purred in ecstasy as Brian went down on me.

"Louise, I want to fuck you. Will you take the cock?" he pleaded.

"Yes, Brian, yes, please, fuck me hard. Fuck me like the bitch I am," I moaned.

Brian eased his erect cock into my wet pussy, grasping both my arse cheeks as he pumped his hard cock into me, slowly building up his rhythm as I gasped at his powerful thrusts.

"Oh, yes, baby, yes, give it to me. Fuck me, Brian, I want your cock in me," I sighed.

Brian was hungrily pumping his cock into me as he sucked on my right breast and gently toyed with my arsehole with his finger. I found this a massive turn-on. He then slowed his thrusts down to slow, long, hard strokes. This I found even more erotic, heightening my excitement even more. I grabbed his bum cheeks, pulling him deep into me.

"Oh yes, baby, yes, give it to me, Brian. Ride me, I want your spunk," I begged.

Brian then spread my legs as wide as he could, lifting both my legs over his shoulders and pushing his cock all the way into my soaking pussy until, with a massive thrust, his body stiffened, and he exploded a large stream of semen deep into me. As he came, I suddenly burst into a shuddering orgasm myself. We both collapsed, hugging each other on the couch.

No words were exchanged between us for a time. Then, Brian quietly said, "Louise, I'm not sorry about this, but please believe me, I didn't plan this. You were a great fuckin ride."

"I know, Brian, but sometimes life leads you rather than you leading life. Things just happen." I replied quietly. "I'm not ashamed this happened, Brian, but I'd really appreciate if we keep this to ourselves. I know Robbie is into me sleeping with others, but I don't think he would take this well," I said.

"Louise, I appreciate you don't think much of me, but seriously, I have as much to lose as you if Rab gets to know about this. So, this is our secret," he assured me. "Can I ask you, Louise, do you really love Rab?"

"Believe it or not, yes, I do. That is why I go along with his fantasies and fetishes. I'm not really a nymphomaniac, but I do enjoy sex," I told him. I reached down to give his flaccid cock a little stroke, and it began to rise. As his cock stiffened, I whispered, "I want it again, Brian," while stroking his cock.

"If you're sure, Louise?" he answered.

I turned to face him, slid down, and took his cock in my mouth, slowly sucking. "Does this answer your question?" I purred. "Do me doggy-style this time, Brian. I love it, and please spank me while you ride me."

I got on the floor on all fours and felt Brian's hands on my hips as he slid his cock into me and began to pump my pussy furiously. As his rhythm quickened, he gently started to smack my bum.

"Harder, harder, Brian spank my fat arse," I pleaded. And as he furiously fucked me, Brian spanked my arse hard, stinging as we fucked. He pounded my pussy furiously for a further ten minutes before he gave a grunt and shot another hot stream of sticky spunk into my swollen pussy. We both collapsed on the floor totally spent and both well satisfied.

"My God, Louise, Rab is one lucky, lucky man; you are a fucking ride," he panted.

"Thank you, you're not too bad yourself for a selfish prick," I laughed.

Brian then got up and got dressed before giving me a long, hard, sticky goodnight kiss and leaving for home. Me, I returned to my drunken husband's bed and prepared for a torrid sex session in the morning, and he'd be none the wiser.
