The morning light filtered through the high, narrow windows of the chamber, casting long shadows across the stone floor. Sarah, or what was left of her, remained chained to the floor, her face buried in the trough of slop. The creature that now inhabited her body had shown no signs of slowing its consumption, its greedy grunts and slurps the only sounds in the otherwise quiet room.

The heavy wooden door creaked open, and a new figure entered. She was tall and severe-looking, with sharp features and dark hair pulled back into a tight bun. In her arms, she carried an ancient leather-bound book, its cover embossed with a silver pentagram that seemed to glow faintly in the dim light.

"Good morning, little one," the nun said, her voice surprisingly soft and melodic as she approached Sarah. She knelt down beside the trough, her black robes pooling around her. "I am Sister Helena, the Keeper of the Sacred Texts."

As she spoke, her hand slid beneath Sarah's body, her fingers expertly finding the folds of her pussy. She began to stroke and caress, her touch gentle but firm, eliciting a series of low, hungry grunts from the creature piloting Sarah's body.

"I see you're enjoying your breakfast," Helena murmured, a small smile playing on her lips. "That's good. A growing girl needs her strength."

Her fingers moved with practiced precision, circling Sarah's clit, dipping inside her, then returning to the sensitive nub. The creature responded with increasing enthusiasm, its grunts growing louder, its body beginning to rock slightly in time with Helena's movements.

"Would you like to hear a story?" Helena asked, her voice taking on the cadence of a lullaby. "A story from our most sacred book, the Chronicles of Adephagia?"

The creature grunted again, a sound that could almost be interpreted as agreement. Helena took this as consent, opening the ancient book and beginning to read.

"Once upon a time, in a faraway land, there lived two curious little piglets—a brother and sister. One day, they decided to wander into the forest, despite their mother's warnings. They walked and walked, until they came upon the most marvelous sight they had ever seen: a cottage made entirely of gingerbread and candy, with frosting windows and licorice doorframes."

As Helena read, her fingers continued their work, Sarah's body responding with a growing arousal that Sarah herself could only experience as a horrified passenger. The creature's pleasure was becoming her own, its desires merging with her consciousness.

"The piglets, being the greedy little creatures they were, began to nibble at the cottage. But as they ate, the door opened, and out stepped an old witch with a warty nose and a cackling laugh. 'Come in, my dears,' she said. 'I have as much food as you could possibly want, and more.'

The piglets, forgetting all about their home and their mother, eagerly followed the witch inside. For days, they ate and ate, their little bodies growing fatter and fatter. The witch had bewitched them, you see, with a spell of unending hunger. They forgot everything but the desire to eat, their minds consumed by their growing obsession."

Helena's voice grew more intense, her fingers moving faster, more insistently. Sarah felt the creature's arousal building, its twisted desires fueled by the story.

"Soon, the piglets were so fat they could no longer move. They were immobile blobs of flesh, their tiny legs useless beneath their massive weight. This was when the witch revealed her true purpose. She was preparing them as sexual offerings for a powerful demon she planned to summon. But this demon had a massive phallus, and the piglets would need to be trained to accommodate him."

With her free hand, Helena produced a large, flesh-colored dildo. She worked it slowly into Sarah's anus, the creature's body eagerly accepting the intrusion. Sarah, trapped in her own mind, could only watch in horror as her body was violated, the creature's pleasure flooding her senses.

"Weeks passed, and the witch subjected the piglets to ever more monstrous dildos, stretching their anuses to impossible sizes. She force-fed them at an accelerated rate, their asses growing into massive monstrosities with enormous, loose, gaping holes. When she was finally done, they were unrecognizable as the piglets they had once been—they were massive, obese blobs of flesh, their asses ready for the demon's use."

Helena's fingers flew across Sarah's clit now, the dildo pumping in and out of her ass. The creature's grunts had become a steady, rhythmic sound, its body writhing with pleasure.

"The witch placed the piglets in a massive summoning circle and began her incantation. The demon appeared in a cloud of sulfur and smoke, its massive penis immediately apparent. The witch and the demon bargained, and they came to an agreement: the sexual offerings would be given in exchange for magical powers that would allow the witch to hex people into becoming incredibly obese."

The story continued, detailing the demon's brutal rape of the piglets, first the female, then the male. As Helena described the demon penetrating the female piglet's asshole, she worked the dildo deeper into Sarah, her fingers moving with frantic intensity.

"The demon raped the little piglet for hours, until her mind was numb and exhausted. Finally, he had an orgasm, coming gallons of cum into the piglet's bowels. The piglet noticeably swelled in size as her insides were filled with the demon's seed. Then he cast a spell on her, sending her into non-stop orgasms that would continue without end."

Sarah felt the creature's arousal reaching a fever pitch, its pleasure overwhelming her senses. She was trapped, a passenger in her own body, experiencing every moment of the creature's perverse ecstasy.

"Pulling his massive filthy penis out of the female piglet, the demon then turned his attention to the male piglet. He spoke his appreciation for having a jack, then cast another spell on the male piglet, causing its balls to wither and disappear and its penis to shrink to the size of a thimble. Then he proceeded to rape the male piglet, stuffing its asshole with brutal abandon."

Helena's voice grew breathless, her own arousal evident as she continued to work Sarah's body. The creature's grunts had become desperate, eager sounds, its body trembling on the brink of orgasm.

"Another few hours passed as the piglet was brutally raped. Then the demon came again in the male piglet's ass, filling up its insides and causing the piglet to grow even fatter. The demon said that the offerings would do nicely and gave the witch the agreed-upon magic. Then, the demon and the two piglets disappeared from the summoning circle and reappeared in a hell-like realm."

Helena's voice took on a dreamy, distant quality as she described the final scene of the story.

"The piglets found themselves face down in beds that looked like evil thrones, their asses exposed in the air. Behind them, hordes of demons stretched out in a single file line that went farther than the eye could see. All of them waiting to take their turns, raping the piglets. And they lived happily ever after."

With those final words, Helena worked Sarah's body into a fevered state of arousal, her fingers and the dildo moving in perfect, brutal harmony. The creature's pleasure reached its peak, and Sarah's body convulsed in a powerful orgasm.

And then, mid-orgasm, the possessing spirit spoke its first human words, a guttural, ecstatic cry: "Yes! Yes! Yes!"

Sarah, a trapped and horrified passenger in her own mind, felt a new wave of terror wash over her. The pig demon possessing her was gaining cognitive ability, learning human language from the act of possessing her mind. And as she listened to the creature's enthusiastic response to Helena's question of whether she would like these things done to her, Sarah became terrified that the nuns might be actually capable of summoning a demon to do this to her in real life. The story was not just a fantasy—it was a blueprint for her future, a glimpse into the hell that awaited her.
