Claire woke up hours later, still feeling hazy and lightheaded. She ignored the soft pulsing in her abdomen as she pulled herself to her feet, wandering toward the kitchen without bothering to grab her robe. A sudden jolt shot through her, starting between her legs and seeming to shoot straight to her nipples. She leaned against the wall to steady herself, and looked down to see her legs parting slowly, her hips rolling in slow thrusts of their own accord. Claire's eyes glazed over as she dropped to her knees, the ache in her belly intensifying as the lips of her sex swelled and flowered open. Her head dropped back and a soft moan escaped her lips as her hips slammed forward, pushing upward, and her entire vulva tightened and quivered in an intense orgasm.
She wrapped her arms around her middle as a feeling of pressure built inside her abdomen. Claire looked down again, awestruck as her belly began to swell just above her sex. Every half-minute or so, another contraction passed through her womb and sex, and her uterus bulged out further with a renewed surge of growth. Claire fell suddenly onto her back as her leg muscles went slack suddenly, and she stared helplessly at the bulging mound of her abdomen, watching the ripples and swells play across its surface as her uterus quivered and spasmed within her. Her hips instinctively thrust upward as each spasm passed through her womb and her mons tightened, little groans escaping from her lips despite her growing hysteria. Claire managed to right herself after several minutes; her abdomen now bulging out about 8 inches in a slight curve. She managed to catch hold of the side of a bookcase just as another contraction rippled through her swollen uterus, her belly straining and bulging out further as her vulva swelled even more between her legs. Another spasm quickly followed, and her hips bucked violently forward as a wave of pleasure surged out from her womb.. which was growing ever faster into a bulge the size of a volleyball, starting to sag in front of her as the life in her greedy, fertile womb grew stronger.
Claire continued to cling to the wood panel of the bookcase, her eyes glazed over, tiny moans slipping from her as her hips bucked repeatedly, responding to the spasms in her swollen cunt, looking down in detachment as her abdomen bulged further outward, ripples and spasms jolting her with waves of pleasure as her uterus shuddered around the life she so craved.
A sharp cry spilled from her lips, as abruptly her womb tightened around its contents. She fell back against the side of the couch, her thighs spreading apart involuntarily as spasms rocked her lower body, dilating her cervix, and beginning to tighten her womb around its contents. Waves of pleasure began to radiate out from the mountainous bulge of Claire's abdomen, sending spasms through her lower lips. The only resistance she was still capable of to the strange hungers controlling her body, was to refuse to push as the contractions started in her uterus, despite instincts coaxing her to do just that. It didn't matter, however, and as she lay helpless on the floor, her fertile womb began to contract intensely in slow rhythm, forcing wheezing grunts from her even as intense shocks of pleasure shot from her womb straight to her clit with each contraction. This continued for a quarter hour, even as the bulge in her abdomen, still squirming visibly, moved lower in her and entered Claire's birth canal. She tried to scream as she felt her labia start to stretch around the life being pushed out of her, but all that escaped was a strangled gurgle. Claire thrashed feebly while her thighs were forced even further apart, as something she could not see began to slip out of her body. As the new life was pushed completely out of her, she at last opened her eyes and looked down at her abdomen, wondering why she still felt a heavy weight inside her, only to see a smaller, but still impressive swell in her belly, still moving, telling her there was another of.. whatever it was.. still waiting inside her, wanting to be born.
Trembling visibly, Claire stood up, avoiding looking at the floor, desperate not to see what it was that her womb had already nurtured, even as she was intensely aware that another life still moved inside her, growing ready to emerge. Tottering on her weakened legs, but in surprisingly little pain from the birth, she stumbled into her bedroom, her only thoughts being to escape this nightmare by falling asleep. She couldn't even walk, managing a spread-legged waddle, the mound of her cunt bulging down between her legs, still swollen from the passage of the first creature, but healing quickly and preparing for the next. Every few moments, the muscles in her outer lips fluttered visibly, quivering and sending soft shocks of pleasure into her.
Just steps short of the imagined sanctuary of her bed, Claire stopped dead as a spasm traveled up her legs, spreading them apart. Another involuntary muscle contraction thrust her hips forward, and the lips of her mons bulged out even further for a moment and something pushed at them from inside, then her labia began to visibly moisten and part, loosening their taught closure. Terror rising in her again, Claire looked down, seeing ripples travel along the mountainous dome of her belly, which stood nearly 2ft beyond her hips, just as she felt a sharp jolt of mixed pain and pleasure shoot along the length of her belly and into her breasts, from which drops of milk gathered on the nipples. She needed little consideration to realize that she was about to again be forced to give birth, to give in to the fertile imperative controlling the processes of her body. "No, please, not again.." the words trailed off into a low moan as a contraction tightened her uterus, and the intense shock of orgasmic pleasure laced with pain dropped her to her knees in a squat, her birth canal bulging out prominently between her legs, the lips flowering open as another spasm completely dilated her cervix, readying her for labor. Claire fought to resist the growing urge to push, even as an intensely arousing ache formed low in her belly, her uterus fluttering and shaking the surface of her belly as if it tried to entice her to fulfill its need. something tensed against her clit, and Claire could no longer resist the growing need, and cried as she helplessly began to push, unable to stop, then screaming in mixed pleasure and pain as both intense orgasms, and the unbearable stretching in her birth canal, rewarded her efforts. Several more wavelike spasms rippled through her gravid uterus, and each time Claire was unable to stop herself from pushing with them, as the child inside her slid out between her legs, and finally slipped free, tearing one last anguished groan from her as the afterbirth was expelled.
Claire lay crying silently, her eyes shut tightly, not wanting to see what had left her body after growing so quickly. Quite suddenly, she felt hungry mouths close upon her nipples in unison, their suckling sending a surge of arousal through her, and her breasts swelled painfully in the moments before they began emptying of their hot new milk.
Claire's breasts and abdomen ached with dull pain, but she could feel her sex tighten between her legs, drawing back into her, and even as her uterus returned to a more reasonable size, she could feel a soft, needy ache pulsing inside her there. She knew that soon she would be forced to gather seed so she could calve again, even though her womb still held enough seed to satiate its lust a few more times even if she somehow resisted her hungers. Calve... the right word, no doubt. Claire knew with terrible certainty that whatever had seized her, had made her its brood mare, unable to stop herself from birthing more offspring for it.
