My wife, Deborah, and I have been friends with Dave and his wife, Alison, for several years now. We regularly go over for meals and general chilling, and they come over to us as well. Just your regular good friends’ relationship.

We are all in our forties and have been married a similar number of years. Dave is a really good friend, although he tends to like his booze a bit too much. Alison is a petite brunette, and in our group tends to be the quiet one. There’s a saying which goes on the lines of ‘you wouldn’t say boo to a goose’, and although Alison isn’t quite as reserved as that, she tends to be more demure than the rest of us, although at times she and Deborah can yack until the cows come home.

On one weekend, we had been invited over and were looking forward to it. On the day of the visit, Deborah came down with one of these flash bugs and decided she would stay at home. However, she insisted that I go over, and after speaking to Dave over the phone, I drove over with a couple of bottles of wine in hand. A delicious meal was created and served by Alison, and the wine flowed freely.

Afterwards, we sat in the lounge and watched a movie which Dave had selected. He started on shorts and had quite a few. I only had one but had drunk quite a bit of wine and wasn’t really fit to drive home. I was prepared to get an Uber home, but Dave insisted that I stay the night in the spare bedroom. I rang Deborah, and she agreed that it was a good idea and would see me when I returned the following day. By this time, Dave was trying not to fall asleep, so he and Alison went to bed. I followed and retired to the spare bedroom.

I had the bedside light turned off and was just dozing before falling asleep when I heard a noise. It was my bedroom door opening and closing very quietly, but then the bed covers lifted, and somebody climbed in. It was Alison.

She said, “Please fuck me, Mark.”

I said, "Wh-what…?"

She went on, “I want you to fuck me. I want to feel your cock in my cunt.”

“Alison,” I said, “I can’t do that. You’re Dave’s wife. It wouldn’t be right.”

I then realised she was completely nude, and she moved her hand under my boxers and grabbed my cock. I wanted to do the right thing, but my treacherous cock had other ideas and went instantly hard.

“As you know, Dave and I have been married for twenty-odd years. We were childhood sweethearts, and he is the only man I have ever slept with. However, our sex life has been non-existent for some time, and I have my needs. I also want to experience another man fucking me. This would be just between us, and I promise no one will ever know. You’re a handsome man, Mark, and I have often fantasised and masturbated thinking of you. I am as horny as hell, and you can do whatever you want to me.”

“What about Dave?”

“Don’t worry about him. He is out for the count. He would sleep through a bomb going off.”

As she was speaking, she was stroking my shaft, and all my morals went out of the window.

I said, “You’re a beautiful woman, Alison, and I would love to fuck you. To be honest, I’ve also fantasised about you. I want to turn the bedside light on so that I can see you.”

Alison agreed to that, got out of bed, and turned the light on. She did a little twirl, showing off all her attributes. Fuck, she was hot! Small in stature but with a pretty face, shoulder-length dark brown hair, and perfectly proportioned tits which were showing prominently hard nipples, her pussy was clean-shaven, and her arse was to die for. Dave must be crazy not to keep this woman satisfied, and I hoped I wasn’t going to regret this.

I took the bed cover off and asked her to lie on her back. She opened her legs and exposed her perfect, glistening butterfly pussy, and I lay next to her. Her green eyes were full of lust.

I caressed her nipples, which drew little whimpers, and then moved my hand down to her pussy. I lightly delved into her folds to find she was absolutely drenched. I inserted a finger into her entrance, looking for her ‘G’ spot. My thumb lazily circled her clit, and she writhed in desperate expectation. “Please Mark, pleeease….” Alison was so gagging for it, I think she had trouble breathing.

I rolled onto her, supporting my weight with my elbows. Truth be known, this was one of the most erotic moments in my life. My granite cock nestled at her entrance, and I pushed…

The reaction was instant. Alison gasped in pleasure, and her eyes closed. She was deliciously tight, but as she was so wet, my cock slid in balls deep. I stopped in that position, savouring the warm, wet velvet sheath around my cock and then slowly started to fuck her, going in and out.

“Oh, God…it feels soo good," she exclaimed. "Kiss me!”

I did as she asked, and our lips mashed together with our duelling tongues.  Encouraged, I picked up the pace. She started to moan, and her hand instinctively shot down to her clit, while at the same time wrapping her legs around my arse. I only went at it for about a minute, and then she screamed as her cunt spasmed when she came, ripping through her shaking body. I very nearly shot my load, such was the intensity of her orgasm.

Having this shaking body pulsating under me put me in a zone of pure lust. As Alison came down from her high, I withdrew and lay beside her.

“Thank you, thank you,” she said. “That was fucking amazing.”

I was pleased she was so happy, but I figured that since her orgasm was very quick and took the edge off her overwhelming horniness, I was going to do round two once she had rested a while to make it much more memorable for her. I hadn’t come myself, so I thought this would be good for both of us.

After about ten minutes, I told her to get on all fours for a doggy fuck. She eagerly got into position, resting on her forearms, and her sexy arse jutting up in the air. I got behind her and saw her wet pussy present itself for our enjoyment. Christ, it was a beautiful sight, and the scent of her arousal made me even more horny, and my cock was like a steel rod.

I prised her cheeks apart and slid my cock into her cunt. She moaned her pleasure and cried out, "Fuck me, fuck me, FUCK ME!”

I wet my thumb and played with her starfish while jackhammering her. She was moaning and coming out with all sorts of gibberish and profanities. My orgasm was building, and I knew I wouldn’t last much longer.

I was pounding her and yelled out, “Alison, I’m going to cum!”

She cried out, "Cum inside me! I want to feel your spunk in my cunt!” That did it for me, and I roared as I spurted rope after rope into her pussy.

That set her off, and she screamed, “OHH FUUUUCK!!” She gripped the sheet with her hands, and her pussy spasmed around my pulsating cock as we both came hard. She even squirted a little. A quiet one she may be, but damn, she knows how to fuck.

I held myself in place until the inevitable happened, and my now flaccid cock slid out. Her pussy oozed out our combined cum juices and made a sort of frothy sound, an image that would sear itself onto my memory for the rest of my days.

We collapsed into a heap and just lay there. She said, “Wow, that was even more intense than the first one. I love it, thank you!”

“It was very much my pleasure too, Alison. You are one very fine fuck!”

She preened at that, and we ended up with me spooning her and dozing off.

I woke up in the morning, and Alison had already left my bed. I showered and got dressed before making my way downstairs, where I could hear the sounds of breakfast being prepared. Both Dave and Alison were there, with Dave looking a bit sheepish.

“Sorry for abandoning you last night, mate,” he said.

“Don’t worry about it. I slept well in your spare bedroom.”

Alison went about her breakfast preparation and asked me if I would like tea or coffee. She did not show the slightest sign whatsoever of what had happened with us just a few hours earlier. Not a sly smile, surreptitious wink, or anything.

And that was how it was going forward. She never ever referred to that night, even when we were alone together. It was as if it never happened. That actually suited me, as I felt bad for cheating on Deborah, even though I could argue that it was a mercy fuck for Alison. Yeah, that’s a pile of dung!

Has she fucked other men? Maybe, but I very much doubt it. I think she wanted to sample forbidden fruit and was satisfied with that. I just hope Dave learns to appreciate what a very sexy wife he has and sees to her needs before others do.
