I relent the pace, circling my tongue downwards spiralling inside, giving her throbbing clit brief respite but making sure that there was no let up in the unrelenting pleasure.

“Pleeeeaaaaasssseeeee…”

Emily’s complaints were muffled as she gasped, the line between pleasure and pain blurred beyond recognition now. All that was left was the sensation I was bringing, her vision darkened, her mind increasingly given over to her body. “Please” a murmur, a plaintive chant. I take it to mean that she wants my tongue deeper inside and I plunge further, my face enveloped by the warmth of her pussy, my tongue exploring, owning, fucking. It feels utterly wonderful and my cock – rock hard for so long now – twitches with anticipation.

I give her clit a little rest and instead, as my tongue fucks, I slide a tentative finger over her ass. It’s slick with cum, and I test whether she is yet in the mood for me to explore there. If Emily is incredibly turned on she squirms delightfully as I run my finger there, and the response is as perfect as ever. Adding a little pressure, I slowly slide in as my tongue tries desperately to grow, to fill her. I ease my tongue a little, allowing what’s left of her senses to focus on the finger sliding slowly, but unstoppably in and out of her tight ass. The moans are incomprehensible now but there’s an overriding, unquenchable need there, a desperate want to feel my cock deep inside her pussy.

I slide my finger out and focus all my attention on her aching, throbbing, sensitive clit, pulling on it slightly and letting my teeth brush over it. For a moment I think I have broken her, the shriek of delight is so intense, so needed, so animalistic. It’s hard to know where climaxes begin and end and begin again, but I know now that I absolutely need to be inside her. I ease the rhythm of my tongue slowly, reluctantly and stand to ease off my jeans. She cranes her neck for a sight of my hard cock, knowing what’s about to happen, fearing her ability to take another climax, urgently in need of hard fucking.

Standing, I strip and kneel between her legs, her eyes are gorgeous but unable to hold mine, her body occasionally spasming with aftershocks and anticipation, maybe with fear too. I pause for a moment to take her breasts firmly in my hands, enjoying the warmth and softness of them, the hard nipples needling the palms of my hands. I consider straddling her chest, pulling those soft mounds together and sliding my shaft between them. I save the wondered for later, first I need to be inside her, to fully claim my gorgeous sub. I can not help myself fully though, and upon releasing her pert breasts I smack one sharply, the sensation rushing through her sensitive body.

The gasp she emits is delicious and hardens me further somehow. I kneel up a little and take my cock in my hand and run the swollen head of it the length of her pussy, rolling it over her clit with deliberate pressure, forcing muffled moans of pain and delight from as I toy with the reddening breasts, working her nipples, caressing and striking, always teasing her with the rock hard head of my throbbing cock.

Adjusting my hips, the tip of my cock slowly slides into her, trying to make this wonderful moment last as long as feasible. Emily is lost to the world, living entirely in the moment, every pleasure visible on her gorgeous face. She arches her eyebrows and inhales sharply, her lips drawn into an O of pleasure and satisfaction as I slide in. She can do nothing other than be fucked now, bound, spread, giddy on climaxes.

I edge in, knowing I am as hard and as big as feasible, wanting her tight pussy to feel every inch as it slowly fills. I can feel her squeezing around me, almost welcoming me, enveloping me, urging me on. I wait till I am fully inside, my body against hers, my balls wet from her already.

“Would you like to be fucked now Em?”

I’m not sure what response I expect, she barely even hears me let alone is able to process what I’m saying. Her skin is flushed red from the exertion of the last thirty or so minutes and I know that her body is entirely mine to do with as I wish. As all the time Emily’s submission is utterly comprehensive, utterly perfect.

Planting my arms either side I withdraw my cock nearly fully and powerfully thrust it into her, filling her utterly, my body colliding with her clit and her body bouncing from the impact. It draws a moan that’s almost a squeal from her gorgeous lips. Clearly she needs to be fucked hard. The pillow under her ass provides the perfect angle for me to be deep inside and using my muscular legs for power I start to pound, over and over, one hand moving to grab a fistful of hair as I do.

There are no words that adequately describe the feeling of fucking her like this, to have a such a gorgeous, submissive, strong woman at my absolute mercy, to be bringing her such pure pleasure. Again and again my body slams into hers, my cock ploughing into her, waves of pleasure crashing over the body that has never felt so alive. I pick up the speed, fast and hard and unrelenting. Her body starts shaking, back arching and limbs pulling hard on the restraints, her delightful moans louder and louder.

At no point do I stop, like an unrelenting piston I keep hammering, her cries of pleasure just keeping me impossibly hard. I fuck right through her climax, prolonging it, and then after it too, drawing it out. Emily convulses as the aftershocks run through her, her pussy even more sensitive now. Her breathing regains equilibrium and her moans soften, her hips and body writhe gently to get to disengage me.

As soon as it’s obvious that I’m remaining in place, albeit with a slower stroke, she pleads for me to stop, saying that she really, honestly can not take any more. Firmly I pin her down, clamping my hands on her shoulders. Her face is turned away from me and I lean into her ear and growl menacingly.

“Emily.You’re done when I say you’re done”

I start to fuck harder, holding her in place as I do, meaning my thrusts are even deeper, the impact on her poor clit all the more deliciously painful.

The secondary orgasm is quickly on the heels of the previous, larger one. It’s impossible to distinguish where it ends and the rebounding aftershocks begin. My cock is clamped tightly inside her and my climax starts to create too, brought on as much by the intense pleasure she’s clearly experiencing as it is by the utterly enthralling physical sensations. I have no intention of coming yet but fuck knows its hard not to when Emily is mine like this.

Emily sees the question I am posing myself, the way my body has stilled with my cock buried deep inside her, her exquisitely tight pussy clamped tightly around my girth. “Please. Don’t. Stop.” she manages to pant, her voice quivering as pleasure pulses through her. Even now, woozy from multiple climaxes, bound and fucked hard she still has the temerity to tell me what to do. My hand instinctively reaches for her defenceless throat and Emily, in her perfect submission raises her head slightly, offering it to me. My hand is strong, half squeezing, half pinning her down.

“Oh really Em? Think I should keep fucking you hard? Fill you with my cum?”

She nods, her eyes as gorgeous as they ever have been. Although the Dom in me tells me to punish her, instead I hammer my cock into her receptive body, the force making her dance underneath me, despite the hand at her throat. Her screams, because that is what they are now, are music to my ears and let me know that this is precisely as hard as she needs it. For a moment I regret her bound position as it prevents me from flipping her over and fucking her even harder from behind, her exquisite ass cushioning each impossibly hard thrust.

I need to remind her just who’s in control and slow right down, her low moans a complaint whilst still being enthralled with pleasure. I edge away and kneel, cock still inside that perfect pussy, but now the angle has changed and I can see the bulge of my cock moving inside her, making the small, trim rectangle of hair move as I slide slowly in and out. It looks incredible and I tell her so, although I doubt whether she can hear me any longer. My hands run down from her throat over her pert and still pinked breasts. I make sure my fingers are firm and drag over them, catching her nipples, hard for me as they all the time are. The clamps in my bag will look incredible on them later, once I’ve made her utterly mine.

The rhythm is torturously slow, my fingers white with the pressure I’m exerting on her thighs. It holds her still as I create the speed, the pillow, utterly drenched by now, holding her ass high and her pussy at the perfect height for me to impale her. Harder and harder now, the pace building, her clit taking and loving every blow of my pelvis, my cock impossibly deep within her. Emily closes her eyes and once more gives herself over entirely to the sensations, the wonderful things being done to her incredible body. Nothing exists aside from pleasure and pain, although they are the same thing right now.

An impossibly intense climax builds in both of us, my pace furious, brutal almost with the force I am fucking her. Again and again I drive my hips forward hard, impaling her on my iron-hard rod. Her howls of encouragement and protest spur me on and on, until I can hold out no longer and thrust my hips forward, burying myself entirely inside her and shudder. The twitching of my cock inside her is precisely what is needed to take her over the brink of a powerful, transcendent climax. I come hard, my cum hot as it fills her, my cock rearing again and again.

My orgasm seems to last forever, wracking my body with pleasure that only she can bring. Each time I move inside her body reacts exquisitely and we have gorgeous chain reactions of pleasure. The clamping and butterflying of her pussy around my shaft keeps me hard and for a moment consider carrying on, but think she’s earned a rest and some aftercare.

I carefully, reluctantly slide my still hard cock out and undo the restraints at the bed, making sure that they are still attached to her wrists and ankles, for future use and to help remind her of her role today. To further that I take a length of thick black velvet from my bag before laying next to her. She’s docile right now, occasional aftershocks wracking her body still, and so lift her head slightly and slide the velvet underneath to secure it around her neck firmly. I want her to be in no doubt it’s there but not so tight to restrict breathing. Finally I shift the covers, roll her onto her side and bring her head to my chest, her arm and leg draped over me and the duvet on top, warming her goose-bumped body. I run my hand through her hair making sure she’s gently brought back to earth after an intense hour, all the better that she can maximise the rest she’s getting now, I’ll require her body for my pleasure again soon enough.
