A what? A fucking machine!

All people involved are over 18.

"Don't you fucking dare, leave it on, oh fuck I'm only fucking cumming again."

I heard D, husband and John discussing my cunt as this thing in my cunt just kept fucking me and making me cum over and over.

"Come on Anna, you greedy cunt, don't fucking hog it, I want to try it." My best friend Sue was shouting.

A couple of weeks ago Barry, my husband's boss, was staying with us overnight before they left early to see a potential client.

I was nearly 30 years old, short dark hair, pert bum and tits, oh, and I love sex.

The first time I met Barry was one evening when I was expecting my husband Derek, or D as I call him. I was lying on the floor, just inside the front door in my stockings and suspenders, legs wide open and wearing an eye mask.

It was a ritual we enjoyed; he'd come in, pretend to be someone else, using a different voice, and just fuck me. Only this time he was with Barry!

I was enjoying getting fucked, I had my legs wrapped around his waist as his cock ravaged my eager cunt. He was using a Brummie accent, telling me how he was going to fuck my dirty cunt over and over. It took me a while to realize this cock was a bit bigger than my husband's.

He was a good two or three inches longer than D was. I grabbed his ass, pulling him into me as another cock was presented to my mouth, which I eagerly started sucking on.

It wasn't long before I was cumming as they used me. My cunt was soon filled with his spunk, a nice load too. D pulled off my mask and introduced me to Barry as his cum filled my mouth.

"Hello Barry, nice to meet you, and I hope you're going to fuck me again."

That was a couple of years ago, and yes, Barry fucked me every time I met him.

By trade, he was a toolmaker, and a very good one, I understand.

Anyway, as I was saying, this evening after I had entertained them both, a nice dp and sucking them both off, they started talking about some machine.

"It's designed so a woman can pleasure herself whenever she wants. It's got a speed control that's easy to use and apart from when she needs to adjust the speed, leaving her hands free to do whatever she wants."

D seemed to understand it; I didn't have a clue what they were talking about.

"I've got a local couple of lads with a machine shop building it for me, should be ready soon. Just need someone to try it for me!" He said, looking at me.

"How does it work then?"

"Well, it has this arm sticking out that's powered by the engine to continually go backwards and forwards. On the end you can fix whatever you want, a dildo of any size, or even two possibly. You just lay there, put it up your cunt, switch it on, and it will fuck you for as long as you want."

"I'm trying to make it with a lighter, smoother and quieter motor and you can adjust the stroke length." He was telling D as I pulled Barry's cock out and started sucking it.

"Go on then, I'll try it," I said between sucking his cock.

After we all fucked and I'd drained their balls dry, I started imagining getting fucked continually. My cunt was twitching as I thought about and the next day, after they had left, I called Sue, my best friend.

She was a lot like me, sex mad and was soon begging me to let her have a go as well. As luck would have they had planned to visit us that weekend. Her husband, John, was all for it as well.

I should explain that we had been swapping partners with them from before we were married.

So on that Saturday, after we had spent Friday evening fucking and sucking each other off, Barry turned up with his fucking machine; well, he turned up. The two lads brought it a bit later, after all they had built it.

Barry had let them in; I suspect they hadn't expected to see two naked ladies.

Mark and Steve, they were called, about mid-twenties, quite attractive, I thought. I saw Sue looking at them as well; she loved cock as much as I do.

I wasn't expecting them and was sat naked next to D. Barry had got up but they had been playing with me on the premise I needed to be nice and wet and horny before I tried the machine. Sue was sucking John off.

"Don't worry guys, come on in. Say hello to Anna and Sue, our two volunteers for it."

We both said hello as they carried this thing in. It wasn't as big as I expected, apart from the long shaft they quickly attached to it. Their eyes were mostly looking at two naked women.

Sue and I just smiled at them, noticing the bulge in their trousers.

"There you go, Barry, all done," Steve said as they turned to leave, still looking at us.

"Thanks guys, you don't have to leave, I'm sure the ladies won't mind, and it's only fair that you see if it works."

Barry opened his briefcase and had a selection of dildos, choosing an eight-inch one and screwed it on the end of the long shaft. My cunt was twitching just looking at it as he rubbed some lube over it.

"I think we need a mattress or something for Anna to lie on, to get the height right for it to be comfortable." John and D quickly fetched one from our spare room.

He plugged it in, switched it on and it made a soft whirring sound; the shaft started moving as he turned a button. The shaft was moving backwards and forwards, slowly at first, then faster as he turned the button.

I was slowly rubbing my cunt as the thought of being machine fucked approached.

"Lay down then Anna, let's get it just right for you." I lay back on the mattress, my legs open, my cunt glistening with my juices.

Mark and Steve were just looking at my hairy cunt, I was just rubbing it slowly, keeping it moist.

"Are you sure we can watch?" Mark asked.

"Of course you can, guys; we don't mind, do we, Sue?"

Barry positioned it at the end of the mattress; although it was a long shaft, I had to move so my knees were at the end of the mattress.

As I slid down, he held the dildo and guided it up my cunt, I shuffled forward until it was right up my cunt.

"Ready, Anna, I'll turn it on slowly at first, then say if you want it faster."

I nodded, as I felt it move, nearly out of me cunt, then right back up inside me as everyone stood around watching me. He left the speed button alone as the machine started fucking me. I was rubbing my tits, squeezing my nipples as I got used to it.

"A bit faster, please."

"Fucking hell, look at it going up her cunt, I've got to get my wife to try one," Steve said.

The machine speeded up; I was getting a good fucking now. I saw Sue, having pulled the two lads' zips down, holding the two lads' cocks, as they all watched; it was feeling better all the time.

I reached for the control button, turned the speed up; fuck, it felt good. I was rubbing my clit as my orgasm hit me. I was still cumming as Sue insisted she wanted a go.

Reluctantly, I swapped places and John put the dildo, still covered in my cunt juices up her cunt, and switched it on.

"Oh fuck yes, who needs a cock when you have one of these?"

Sue was playing with her nipples as I leant over to kiss them.

I happened to be right in front of Steve, his cock sticking out close to my rear. I heard Barry say, "Why don't you fuck her, Steve as a reward for making it? You don't mind, do you, Anna?"

I just wiggled my ass.

"I'm not sure she will feel my cock after the size of that dildo."

I heard him say as he pushed his cock up my cunt. I squeezed my pelvic muscles to grip his cock.

"Fuck, she's still tight, nice cunt Anna."

I mumbled thanks as I was sucking on Sue's nipple. Steve was fucking hard; I guessed he wouldn't last long and I felt his cum filling my cunt. I squeezed harder, encouraging him.

After he pulled out.

Mark said, "Can I have a go, Anna? I helped make it?"

"Why don't you use my ass, Mark? Get it ready for that dildo to fill my bum." I replied, smiling at him.

He grinned as he slid it in my cunt first, then it was pushing at my anus.

"Fuck it's tight, Anna."

"Just push it in, Mark."

I pushed my bum back. I felt the head pop in. I just pushed back on his cock some more and it was right up my bum.

"Go on, Mark fuck her ass; she loves it up there, don't you, you dirty cunt." D said.

Sue was starting to cum, Barry had joined me sucking on her tits, she had both hands on her cunt, rubbing her clit like mad as she came. I'm not sure how it stayed up her cunt the way her fucking hips were moving.

John switched off the machine; all you could hear was Mark's balls slapping my ass as he held my hips tight and gave my ass a good fucking.

I was nearing my own orgasm as his spunk erupted in my ass; he was groaning as he forced it balls deep in my ass. uhh

"Keep fucking me, Mark. I'm nearly fucking cumming." But his cock flopped out of my ass.

"Fuck I was just about to cum, get that fucker up my ass, D."

He grinned as I lay face down; Barry put a pillow under my hips so my ass was up a bit. D fed the dildo up my bum. I had my hand on my cunt as D switched the machine on.

"Oh fuck that's it, faster you bastard, I'm nearly cumming."

"Look at that thing going in and out of her ass, my wife screams like fuck when I put my little cock in hers." I heard Mark say as I was rubbing my clit harder.

Then Barry sat by my head and offered his cock to my mouth. I opened my mouth and was greedily sucking on his cock as my orgasm hit me.

The machine didn't care; it just kept fucking my ass. I was still cumming as Barry held his cock and filled my mouth with cum.

D went to turn it off.

"Don't you fucking dare, leave it alone. Is there a bigger dildo, please, Barry?"
