It’s fifteen minutes past midnight when I finally knock on the front door of a smart dockside apartment; a part of a warehouse conversion. I’ve hurried here as quickly as I can but we were late closing the bar after the cash register was out by £50.

After what seems like an eternity the door opens and there she is, my mysterious red head.

“You’re late.” Her voice flat and cold sent shivers down my spine.

“I’m sorry, there was a problem with…”

“I don’t care. I said midnight or else,” she cuts across my hurried words. “If you still want to cum you can come in but there is a price to pay for your tardiness.”

She looks at me expectantly and I nod in understanding, my mouth dry, my voice a whisper that I don’t trust. She stands back from the door and I step into her loft. We’re on a landing with stairs leading down into the living space.

“Stop there,” she commands and I halt, my breathing as tight as my knotted stomach. “Strip!”

That one single word stops my thoughts, I was expecting a nightcap, a cuddle and a resumption of our earlier liaison but this is cold, authoritarian. I step out of my heels and pull my tee over my head, then I slip my leggings down below my knees and they fall to my ankles allowing me to step out of them. I feel so vulnerable in front of this strange woman, clad as I am in just a black lace bra and thong.

“I said strip. That means everything,” she snaps at me.

I comply without a word and stand before her naked. She is wearing a very sheer white kimono, her red hair a stark contrast against the pale silk. She steps towards me and without a word slaps me across my right breast, I jerk back and squeal in pain and shock.

“I said there would be a price,” she repeats and slaps my other breast. “Still want to cum?”

I breathe deeply. 'Oh fuck, what have I got into?' I ask myself. My breasts are stinging but I’m conscious of my pussy getting wetter.

“Yes please, I still want to cum,” I reply.

“Good. Follow me,” and she descends into the living area of her loft and I follow down the stairs, watching as the kimono moves sinuously over her body.

Arriving at her couch, deep red leather and overstuffed, she turns to me.

“You will bend over the back of this couch.”

I do think of asking why but an inner voice tells me to accept my fate, and so I bend over as instructed.

“That’s it, trust and obey me and you will know pleasure like never before.”

My hostess has moved behind me and is slipping loops of silken rope around my ankles. Moving in front of me, she repeats the action with my wrists and as she pulls she ropes taught I find myself being forced over the back of the couch, my ass in the air. I can’t move with my ankles connected to my wrists via the ropes which now run under the couch.

“Of course to appreciate pleasure one has to appreciate pain,” she continues and strokes my face with a strip of soft leather. There is a hint of cruelty mixed with arousal as her voice becomes a little huskier.

“This is a flogger, and I’m going to be using it to warm that sweet ass of yours,” she purrs.

She is holding the leather in front of my eyes. Then suddenly, unexpectedly, she swipes it firmly across my ass cheek.

“Urrgh.“ My voice is muffled as my face is buried in the soft upholstery of the couch.

“Quiet my darling. We don’t want to disturb the neighbours, do we?” As she speaks so she rhythmically swipes my ass, the light stings building into real pain as each new swipe hits a previously tenderised spot. The heat in my ass builds and I concentrate on keeping quiet as my arousal builds, my pussy starting to flood and my juices reaching my thighs.

“Enough I think.” Abruptly she stops swiping my poor ass and strokes it with her hand, letting her fingers part my ass and trail through my wet folds.

“Oh God, was I right about you.” She is speaking to herself, not to me. “I could see this in you, the need to be taken and controlled.”

She has stepped in front of me and I lift my head to look at her, drool running from my lips.

She is holding something shiny, it has a red crystal end to it and the shape reminds me of a large chess piece.

“In case you’re wondering, this little beauty is a stainless steel butt plug. Do you ever pleasure that prissy little ass of yours?”

I nod, my inhibitions long gone. “Yes, but just a finger, never more.”

“Well then, you’re going to find this a bit of a stretch.” She chuckles and starts rubbing the cold metal against my hot wet pussy.

“Good job you’re such a wet bitch.”

She’s drawing my juices along my perineum, using my lust to lube my ass.

“That should do it. Now, breathe deep and relax.”

The pressure against my ass is building, I can feel my entrance stretching. Oh fuck, not nearly enough but the pressure mounts.

A long groan escapes my lips as my ass is invaded, stretched, a sharp hot pain and then throbbing and a sense of being so, so full.

“Well done.” Her hand caresses my cheeks. “Now relax and let your body adjust.”

She has released the ropes allowing me to stand and I’m suddenly conscious of the weight in my arse.

“Oh fuck. Oh fuck, fuck, fuck, I have never felt so horny in my life,” I pant.

“Good now walk to my bedroom. It’s over there,” she points the way. “And don’t you dare drop that plug on my hardwood floor.”

I clench and waddle a little but my sore and newly bunged ass and I make it to the bedroom without losing the invader.

“Turn to face me.” She sounds more tender and I turn in to a long tongue laden kiss, her hands caressing my sides, stroking my hot ass, still throbbing from the flogger and now full of cold steel.

“Close your eyes.” Her hands are cupping and caressing my breasts, her thumbs rubbing and stretching my nipples. “Keep them closed. Remember, trust me,” she whispers in my ear, her breath warm across my cheeks.

“Ah, fuck!” I scream as a white hot pain shoots through my nipples.

“Just a little clamp honey.” She offers my full firm breasts up for my inspection.

I look down to see my large dark nipples, gripped by two shiny silver crocodile clips, the little teeth biting into my sensitive nubs.

My senses are overwhelmed, my ass freshly flogged and bunged and now my nipples burning and all I want to do is cum, my clit throbbing, like toothache, with need. My new friend pulls the bow at the waist of her kimono which parts to reveal her taught body. Her skin is as pale as milk, her nipples just a blush of pink. My eyes drop to her pussy; pale pink lips swollen and slick with arousal and that large tuft of red curls atop it.

She drops her shoulders and the silk slides away to the floor, then she pushes me backwards. My legs hit the bed and I fall backwards into a sea of pillows. As I land I’m conscious of the plug pushing deeper inside me. She leans forward. I feel her breath on my pussy, then the warm roughness of her tongue as she drags it across my lips, her tongue parting my labia as the breath rushes from me. Her finger enters my pussy. I’m soaked, and my juices are flowing freely and I buck and spasm in response.

“You ready to cum Lisa?” she asks me with a smile.

I don’t know where she got my name from but I pant yes, my breath ragged with need and anticipation. Her head dips and she smothers my slit with her mouth, her tongue probing my depths. My hips buck as my wave breaks. I can hear, as if in the distance, screams of pleasure. Are they mine or hers? I don’t know. I’m flooding and she is swallowing my cum hungrily. I’m riding a breaker of pleasure when suddenly she frees my nipples. A pain like fire passes through them as the blood flows back and that wave of pain mixed with the intense pleasure of her mouth at my core is too much. I see lights, bright and confusing and I’m gone.

I awake to a cool feeling on my ass. Angie is massaging a cooling balm into my cheeks, her finger just catching my entrance. The plug has gone.

I feel relaxed and satisfied like never before and I turn and kiss my new-found friend.
