You’re a serum girl in your oubliette.

You awaken, sore and thirsty in the candle lit oubliette beneath your pleasure house. You lay upon the cold stone dias at the centre of the oubliette. Candles, whips, feathers, harnesses, leather fetish wear, silken garments, thongs, corsets, stiletto heels and course **** clothes are laid about the dais. The air is heavy with the smell incense. A sense of the familiar and the alien **** you at once.

You are confused. How did you come to be here you wonder. And then you remember. You stare down at your body, gritting your teeth. It is as you feared. A pair of breasts ride proudly on your ribcage, two large soft mounds of flesh. You have become a curvaceous serum girl, but mercifully you are dressed in **** silks so the fullness of the change is not as confronting. Yet.

By the seemingly increased size of the room you estimate that you have shrunk in stature - five foot tall, perhaps less. Your breasts are large, a D cup? Your waist is ever so narrow. Your hips are wide. Your legs are short and perhaps a little on the heavy side. Your feet and ankles are tiny and delicate. A thick mane of honey coloured curls falls about your face. Your skin is naturally dark and tanned. Peaking beneath your top you see that your nipples are large and dark ruby. You look down between your legs, pulling you loin cloth away. Your hairless sex is large, with a pronounced labia nestled tightly around your inner folds. You swallow in fear. The **** collar about your neck and chained to the dais makes your face redden.

You touch your ample breast thoughtfully. Your chest rises and falls with your breathing. The nipples respond pleasurably to your touch. You gasp and the harden your mind, screwing your resolve with your anger at what has been taken - stolen from you. If you have your way you will sublimate your natural **** urges. You will become a lash mistress, breaking in other serum girls, living vicariously through the submission of others. If you have your way? You laugh in a voice that is high and sweet. Slaves do not have their way.

That you had been duped by Pohst and allowed him to reduce you to this angers you. You ponder your fate as a female ****. It will be a simple matter for Pohst to keep you in rags or naked. You can easily be branded or subjected to the discipline of Khali the lash mistress. You have done as much too many serum girls yourself. It will be easy to break you in this serum girl body.

You stand unsteadily and hunched over as the leash chained to the floor is too short. A training leash? "Overlords," you mutter.

Mocking laughter responds to your words. Then your captor Pohst emerges from the shadows and approaches you slowly. He is a lithe man with dark hair and darker eyes. He towers above you now and scratches his chin with a calloused hand. "Did I give you permission to stand? Kneel," Pohst orders. You stare at him for a moment. "Kneel or I will have you whipped!"

At the raw masculine power of his voice you reluctantly lower to your knees. He approaches with a swagger and you realize that your eyes are level with his crotch. You feel him leering down at you and feel weak and ****. You know he is enjoying this, and as much as you try to deny it, so are you.

"Good girl," he says, "now remove the top. Show me those nice rounded breasts."

With **** you pull your top over your head. Your large breasts are lifted high then one after the other they spill free into the open air, swaying oddly. You throw the top to the ground where it tangles with your leash and shake out your hair. The candle light plays over the exposed curves of your body. Being naked and kneeling before your enemy is humiliating. Pohst's lust for your body is palpable, straining before you in his pants.

He reaches down and fondles your breasts, tweaking the nipples roughly and eliciting some whimpers from you. He grabs a full handful of one, "they are lovely," your captor remarks, "and now the loincloth. Lets see the full effects of the serum."

After a number of clumsy tugs the loincloth slips off your wide hips and down about your knees. The void between your legs feels strange.

"Now, lean back and spread your legs. I want to examine your little bud," he says. You obey haltingly. "Wider girl!" At his order you lean back and spread your legs, raising your loins to him like a common serum girl.

Pohst chuckles as you feel his calloused blunt fingers touching your full pussy lips and teasing the folds of your now yielding sex. You whimper as Pohst's fingers slip gently into your moistness. Your new anatomy quivers and tingles with arousal, clamping reflexively about his digits, as though begging him not to go. "Oh Overlords," you moan. Why did it have to feel so good? It would be easier to fight if only it was not so frantically wonderful.

You see the large nipples on your chest grow flushed with blood and become pointed, a thin film of perspiration shining upon your breasts. Looking up at your captor you cannot help but wonder how much better his cock would be than his fingers. As if reading your mind Pohst unlaces his pants and lets them fall to the dais. He continues to finger you as he lowers himself onto your prone form.

"You want this?" Pohst asked. You can feel something resting between your legs, pushing against you. It felt large and round.

"No," you struggle to say realizing that Pohst's penis was pushing hard against the moist lips of your pussy. In spite of yourself you found yourself becoming hot and aroused.

"Are you so sure ****," Pohst asked, gripping your neck chain possessively, reminding you of your now submissive role.

"Yes... no... please," you say. The pressure increased and you feel yourself yielding to him, your lips being pushed pleasurably apart. Ever so slowly Pohst edged into your smooth shaven cunt.

"Overlords!" you mutter as Pohst fills you with his massive member.

"You are so tight," Pohst said as he started to pump you for all you are worth. You grunt and moan as he thrusts deep inside you, your breasts bouncing with every thrust. You become hotter and wetter as he rides you, juices trickling down your inner thighs as sweat beads on your forehead and in the small of your back. You feel your knees start to go weak as the burning pleasure in your groin grows in throbbing waves.

"I'm cumming," you gasp as your first female orgasm wracks your body. Then he cums deep inside, filling your womb with his burning hot seed. He thrust three more times, grunting with each. Your pussy clamps tight about him, holding him tight. Your back arches and your muscles spasm. You collapse together in an awkward, panting, sweating, sated pile of limbs. He starts to soften within you then he pulls out and climbs away. You feel cum and juices flowing from the puckered and red lips of your cunt.
