'A butt plug, a stranger and sounds I'd never heard: A detailed account of mind-blowing sex.'

I was told to wear heels, a dress, bra and no undies.

I was standing in the carport of a very nondescript, small house out in the ‘burbs. It was midday on a weekday. Such an odd time and setting to be embarking on what I was about to do.

My hands shook, and my legs were wobbly and I almost turned around and ran back down the driveway.

But I was here now. I took a deep breath and propelled myself forward.

I knocked on the door and waited.

The blinds twitched and a man answered the door. An ordinary man. Not a hulking great wrestler with a pentagram carved into his forehead, just a normal, good looking guy. Jeans, t-shirt, average height, friendly face, longish curly hair, a discreet nose ring. He smelled good. He had a nice smile. I felt relieved. But I was still freaking out.

I was here to see a BDSM Dominant and there he was, standing before me, looking me up and down.

I lost the power to speak, which was fine because I was to be submissive and apart from a few pleasantries and acceptance of the rules, I was not required to speak very much.

I’ve had a few bum spankings, a choke or two, a bit of hair pulling, and I quite liked it.

But this was different.

Sir (it was Sir, with a capital S) and I discussed the rules, he told me the safe word, what different colours and numbers mean – green is good, orange is not good, red is stop immediately.

One is very mild, ten is very strong. I had filled out a 50 question survey before we met to talk about what I liked and my soft and hard limits and he had read it and come up with a plan.

He asked me if I was nervous and patted my hand when I could barely squeak out a YES.

Then I was ordered to take my clothes off. He said it quietly, but firmly, and I did what I was told.

When I was naked, he circled around me like a shark, inspecting my body, taking it in. He lent in close and sniffed my neck. He said he liked what he saw, and that I smelt good. He didn’t touch me, but he was about one centimetre away from me, and the feeling of his face and hands hovering just next to my skin sent my body into involuntary shudders.

He told me to kneel on the floor with my head down on a black, spongy play mat. A thick black leather collar was dragged over my shoulders slowly and then fastened around my neck. This ritual was slow, practiced, controlled. He then inspected my nails, one hand at a time, and when he was satisfied, he slipped a ring on my finger and told me to keep it on.

I was then ordered to kiss his feet.

For some reason, this felt completely normal and fine. Here I was, naked, in a collar, knelt down on the floor kissing a strangers feet. They were clean and manicured and I didn’t mind a bit.

That was when he slipped a metal butt plug up my bum.

See, in my survey I had said yes to butt stuff. I guess I just hadn’t realised that the survey questions are the end of the discussion.

I started laughing at this point.

It was kind of surreal. He laughed too. I laughed so hard I almost popped the butt plug out. He said I would be in trouble if it came out.

I stopped laughing.

Then I was ordered to stand with my hands flat on the kitchen bench and the spanking began.

He started off slowly and slapped in a rhythmic way. Left, right, left, right. And then he would break the pattern, just when you thought you knew it. It got harder and harder and I could feel my cheeks warming up.

His fingers would just brush my vagina, teasing me. It was both infuriating and delicious.

The spanking continued, then he moved onto the paddle, a black leather one that made an incredibly satisfying smacking sound.

He kept checking in about how I was feeling, if something as green (good), orange (not good) and what number between one and ten I was feeling.

I was kind of losing myself. It was like being high. The pain and then the relief from the pain was like a sexy rollercoaster. The anticipation was addictive.

The spanking went on for about 30 minutes, the crescendo being two whip type things with lots of leather strips attached. There was a sharp sting to them, and but also a lovely soft tickle.

I was so wet by this time; I was dribbling on the floor.

Then I had to kneel in front of him and take his pants off. Slowly.

I pulled down his underpants and most gigantic, hard, perfect penis I have ever seen burst out and hit me in the face, almost giving me a black eye.

I could not believe it was real. It was like those big dildos you see at sex shops and go ‘yeah, as if’.

I put it in my mouth and felt like my jaw was going to get dislocated.

Then the fucking began.

It started with some face fucking, which generally I’m not against, but this giant penis was kind of terrifying and before long I had mascara running down my face and spit all over my face, which he kept rubbing all over me. (I had consented to all this in my survey.)

Then he did that cool thing that some people can really do and stuck his fingers up my vagina and pushed some sort of button and I squirted everywhere. Over and over and over again, until I was in an enormous puddle. I could not believe one lady could make so much liquid from some secret fanny pocket.

I also made note to drink a lot of water later.

After the gushing, he tied me up slowly with this gorgeous pink rope, using intricate knots and kissing me in between. It was super hot. My whole body felt electrified. Then he pulled out this giant vibrating wand and would push it on my clitoris periodically as he wrapped rope around me. My arms were behind my back and one leg was tied up with my arms. I was completely powerless, but I didn’t mind a bit.

Finally I was suspended to the ceiling and so I was just dangling there, on one leg for support.

He checked in again. Was I ok?

Fuck yes.

Then he put a condom on (he must have to buy elephant condoms) and put that ridiculously oversized appendage inside me. It took quite a while to get fully submerged. And, remember, I still had a metal butt plug inside me, which I had managed to keep in, by some sort of sex miracle.

It felt like something might explode, like my internal organs were being pushed to places they were not supposed to go. It was not an unpleasant feeling.

And he fucked me really hard like this for ages, making noises like an animal. He had the vibrator on my clit and there were so many sensations my body went into total meltdown.

I felt like a rag doll. He is not a large man, but he is very strong, lean and super fit. Shagging like this every day must be very good cardio.

So from then on, it was a combination of hard fucking, clitoral vibrating and his mouth on my vagina and then his fingers making me squirt for so long, I truly had nothing left. We were both sweating, panting, making sounds I have never heard come out of my mouth before.

Then he untied me, told me to lie down on a black rubber sheet on a small bed and climbed on top of me and we had more sex and then he came, practically howling at the moon.

I was lying in a puddle of my own juices.

I was in shock and had to pause a moment.

That was insane.

I was told to run us a shower, and then I needed to clean up my mess.

We had a shower together and it was lovely, actually. It’s amazing how close you feel to someone when you’ve put your trust in them physically, mentally and sexually like that. Even a stranger.

We kissed and washed each other.

Then I cleaned up the river of lady juice all over the floor, mats and the rubber sheet using antibacterial wipes, naked, as he watched. I then washed the toys and the paddle in the kitchen sink.

My whole body felt like it was going to shut down. Three hours of pounding, slapping, sucking, and being thrown around had taken it’s toll.

When I was dressed, he gave me a glass of water, told me he was pleased with me and said it was time to go. Was I ok to drive? (I thought so). He kissed me and opened the door and sent me on my way.

I walked down the driveway, feeling as though I had just run a marathon, grinning from ear to ear.

Then I drove straight to the drive through and got the biggest pack of chicken nuggets possible and giggled and nugged up all the way back home.
