The Plunge

"Don't worry," The demon hissed. "I didn't put enough of my essence into your little friend here to do anything too permanent to you on its own. Think of Frank here as a dutiful instructor, keeping you on task while you study."

The demon lowered Frank and pressed his fat head against Luna's tight, virgin slit. The animal heat coming off of the creature was unbearable. The thought of something so freakishly big crawling inside of her paralyzed Luna in abject terror.

Frank wiggled against Luna, desperately trying to part her lips, but the demon held him back.

"Any final words before we begin?" The demon asked.

In the face of the sheer inevitability of her situation, Luna felt a mighty sense of defiance rise up within her.

"I'm not going to be your little servant," Luna said. "I'll fight your control with every fiber of me!"

The demon stared blankly at Luna for a couple seconds before tossing her head back and letting out a loud, high pitch laugh.

"Oh you silly little bitch, I don't want to control you."

"Then why are you doing this?" Luna asked.

"I'm a girl who likes chaos and corruption. When I came across you, this powerful little dynamo of magical potential, I knew I had found something special. If anything, I want to unshackle you from any and all control."

"I don't understand."

The demon shook her head.

"Enough chit chat. I don't have a lot of time."

The demon loosened her grip on Frank and Luna felt the creature's bulk slam into her vagina. A throbbing, painful ache radiated from Luna's crotch as the creature struggled desperately to part her nether lips.

"Oh God no!" Luna gasped.

The demon giggled.

"You're so tight it seems like Frank is having trouble getting it in!" She said. "Why don't I help him."

The demon tightened her grip around the creature's body and jammed him into Luna's pussy, pressing hard on her virgin lips. The pain Luna felt multiplied a thousand-fold, causing her vision to go blank for several agonizing seconds.

There was sudden, sharp tearing sensation in Luna's vagina that made her scream. She felt something wet and warm trickle from her spreading slit. In the next moment, the sinewy bulk of the worm filled her canal, stretching the girl to her absolute limit.

Luna babbled incoherently on the ground as the worm filled her, inch by painstakingly slow inch. It hurt so fucking bad! The agony made it impossible to think.

"How does it feel to lose your v-card to this monster?" The demon sneered.

"Pull it out!" Luna begged. "For God's sake, you have to pull it out. It hurts!"

"Don't worry, the pain will fade very soon," The demon said.

As if on command, Luna could feel the sharp pain fading into a dull ache. A warmth was spreading through her insides as more and more of Frank's mutated bulk made contact with the flesh of her pussy.

Somehow, the relief felt worse than the pain. At least with agony, Luna could properly understand the horror of her situation. Now, all of a sudden, her body was betraying her. Luna could even feel Frank's body moving into her quicker as her muscles relaxed.

There was only one option Luna could think of to make this nightmare stop.

"Frank, listen to me! Your my familiar, not hers. Please stop! Please come out. I'm begging you, Frank."

To her shock, Luna felt the worm slow its pace. It suddenly seemed unsure of its purpose.

The demon, noticing this, frowned.

"Incredible. Even with demon flowing through its veins, your familiar still listens to you. You really are something special," The demon said. "I suppose I'll have to try something more drastic."

The demon grabbed the spell book and flipped through the pages at an inhuman pace, settling on one particular page with a nasty smile painted across her face.

Luna felt Frank's body stretching her insides still. While the pitiful creature had stopped its ****, it still had not come out. Was it even capable of moving backwards?

The demon broke Luna's train of thought by chanting a loud and forceful incantation, her fingers aimed at Luna. Clouds of red energy shot from her index finger. They swirled around Luna before seeping into her flesh.

"Stop it!" Luna cried.

As the energy filled Luna's body, she felt the heat between her legs intensify into a smoldering bonfire. Her pussy suddenly as wet as a waterfall and she could feel Frank starting to stir once more.

Other changes swept over Luna's body as well. Her tiny nipples tingled with feminine pleasure, growing hard and erect. Her skin grew hot and a light sheen of sweat broke out across her brow.

"What did you do to me, you freak?"

The demon tittered.

"Nothing too drastic. Just an orgasmic fever."

"Make it stop!" Luna cried.

She could feel herself losing control. As her pussy burned, she began to thrust her hips into the air involuntarily.

With each new notch of pleasure, Luna could feel her tenuous hold on her familiar fade. The worm began to wiggle and shift its body around inside of her, only making the young woman's arousal even worse.

"Frank, please. Ugh, you have to-ohhhhh god it feels good," Luna moaned, feeling her body spiral towards a massive climax.

The demon ran her clawed fingers along last few inches of Frank's body still outside of Luna before poking the girl's pleasure bud. Luna yelped in response, bucking her hips wildly as she did so.

"What was it you wanted Frank to do. I don't think he caught that."

"Frank. Frank. You have to," Luna struggled to say. Her mind was going cloud.

"You have to what? Go deeper?" The demon punctuated her words by rubbing Luna's clit even harder.

"Nooooo!" Luna groaned. "Frank. Please. You have to-you have to..."

All of a sudden, it felt as if a dam had broken within the young woman. Her whole body seized up as the heat inside of her burned like a dying sun. All rational thought left her then, her dire need for release taking hold of her.

"Fuck me!" She cried. "Fuck me deep Frank. Oh God, I can't help myself."

"That's more like it, Luna!" The demon cheered.

The worm's reaction was immediate. With one powerful thrust, it shoved the last few inches of its body into Luna's pussy. It moved faster now, Luna's orgasm ridden body welcoming the hulking invader.

Oh God, What have I done? Luna thought.

Luna felt the worm push against something hard inside of her. For a moment, she thought the invasion had finally ended, but in the next she felt a pain unlike anything she had ever felt before.

It was the horrible, aching feeling of being stretched far too wide. Luna could feel the powerful worm shoving itself deeper than should have been possible.

Not there, she thought desperately. Please not there.

Frank didn't listen. The worm **** itself inside Luna's womb, stretching the cavity to encompass its full bulk.

"I take it Frank hit his mark!" The demonic librarian said.

She knelt down and straddled Luna, snapping her fingers to release the girl's restraints. It didn't matter. Luna wasn't going anywhere anymore.

Luna said nothing. She was crying now, sorrowfully resigned to her fate. She could feel her belly swelling outward slightly from the worm's mass, making her look very slightly pregnant.

She supposed this wasn't far from the truth. In a way, Luna was Frank's mother, giving birth to his new form with her magic. It was only fitting that the creature got a proper gestation from its mother.

Then Luna thought of Mary.

Oh Mary, she thought. You were right. You always are. I shouldn't have gotten mixed up in this stuff.

All of a sudden, Luna felt switch flip inside of her. Her mind seized on the mental image of Mary, her body enhanced by the feminine lust spell, stroking the man's cock. The image now seemed so inviting. Luna imagined Mary's swollen titties bouncing as the penis sprayed them in cum.

Luna's thoughts darkened. She would have Mary in the end. It was fate. Why else would they be such good friends? Mary just needed to be shown the light.

The demon sighed.

"I can read your thoughts, you know."

Luna's mind switched to rage as she looked upon the demon that had caused her so much misery.

"Fuck you. I'm going to use that book to find a way to kill you, you bitch!"

"Oooo, now that's a dark thought. Have you ever wanted to kill anyone before?"

Luna hadn't. What was wrong with her mind? Luna felt as if the filter that kept bad thoughts at bay was now dissolving.

"Now you can understand why I stuck Frank inside of you. He's there to keep the sinful thoughts flowing and good ones at bay."

"Why are you like this? Why me?"

"You know why. I've explained it like ten times by now. Witch's blood, powerful magic, blah, blah, blah," the demon said. "Now before I'm torn from this realm, I would like to help you with one more thing."

"You've done enough!"

The demon shook her head and began to unbutton her shirt, revealing a pair of large, pale breasts.

"I know you want that blonde slut. You've been thinking about her titties nonstop. Perhaps I can help with that urge."

Luna growled.

"Get those away from me. And get out of my head."

"Oh calm down and give it a try," The demon said, lowering her breasts to Luna's face.

Luna turned her head away, feeling the warm, bulging flesh push up against her cheek in the process. The demon was massive. She even made Mary in her transformed state seem small.

The smell of the demon wasn't what Luna expected, either. She would have assumed a demon smelled of sulfur or ash. Instead, the demon had a sweet, intoxicating scent reminiscent of berries and vanilla.

Despite herself, Luna felt her body suddenly growing aroused. Mary had been the only woman she had ever felt any real attraction to. Hell, Mary was the only person Luna had ever felt those feelings towards. However, now she felt the familiar burning in her pussy as the demon's breasts bulged in front of her.

They were very nice. Big and perky. Luna wondered what it must feel like to have breasts like that. So much tingly feminine flesh bouncing in front of you. Perhaps she desired the beauty of women out of envy.

Before she knew what she was doing, Luna reached out and grasped the demon's rack with both hands. The feeling of the soft, supple flesh in Luna's hands made her head spin with pleasure.

She squeezed harder and began to play with the tit flesh, making the demon put her head back and gasp.

The demon was an evil bitch, but Luna had to admit that she felt amazing.

Luna felt the demon pat her head and in a soft voice, whisper to her.

"Touching is fun, but wouldn't sucking feel even better?"

The thought wormed its way into Luna's mind like a parasite. She peered at the breasts before her, spying the demon's large black nipples with lust and fascination. She was already this far in, what was the harm of going a little farther?

Luna hefted the demon's right breast and brought it to her mouth. She closed her soft lips around the turgid nipple and began to suck. Within seconds, she felt a trickle of sweet nectar flow down her throat.

Whatever it was, it tasted incredible! Luna sucked harder, using her hands to squeeze out even more of the delicious liquid.

"Oh aren't you precious! You're like a little baby, desperately clinging to her mother. Then again, you've never been close to your real mother, have you?"

Luna nodded slightly as she gleefully slurped at the fat, demonic tit.

"That's okay," the demon said. "I'll be a much better mother to you, dearie."

As much as Luna wanted to hate the demon that had violated her so completely, her voice was making a whole lot of sense now. The more sweet milk Luna drank, the calmer she felt about her whole situation.

Luna managed to swallow several more gulps of the potent fluid before the demon snapped her fingers, producing a bright flash.

Suddenly, Luna was sitting a distance away from the demon, who was now buttoning her shirt up. Luna could still taste the milk in her mouth.

"That's enough for now," the demon said. "Too much in one sitting and you might start growing horns. That would be boring. Now take these."

The demon handed Luna the book and her backpack.

"Run along now," the demon said. "The bells about to ring."

On cue, the fourth period bell rang out.

"But," Luna began to say. Her body felt strange and tingly. What was that milk doing to her?

The demon cut her off with a finger to her lips.

"No more question, I'm out of time. Now go!"

Luna saw in the demon's bright purple eyes that she wasn't getting any more information. She turned around, her body feeling strange and unfamiliar. Reality seemed spotty, as if her life were now captured in a dream.

As the young woman left, the demon watched her intently with predatory eyes.

Without warning, the demon's arm burst into flames.

"Damnit," she said. "I thought I had a little more time. I wanted to play with the dick girl."

Soon, the flames consumed the demon's earthly body. A billow of smoke rose up from the ashes, rising towards the ceiling. In the next second, the fire alarm blared, sending the school into overdrive.
