Kathleen awoke slowly to the sound of rain in the trees and thunder in the clouds. She turned her head to the left and opened her eyes, but there was only a poster with a heavily-armed female frowning at the camera. Blinking in confusion, Kath turned to look the other way, and saw the open door and the closed window. She was in Violet’s room. Alone!
A mystery. She had definitely fallen asleep in her own bed, and she had seen Violet close her door after she entered her room. There had been no more hanky-panky the previous night, not after discovering the new depth of Kathleen’s vagina.
Oh well Kath thought to herself as she reached above her head to stretch. I’ll figure it out after breakfast.
Propping herself up with her elbows, Kathleen slowly took in the odd sight in front of her eyes. Her belly was bulging outward, as though she were at least six months pregnant.
She dropped her hands to her midsection, feeling the new contours to make sure she was not hallucinating. She shook her head in seeming disbelief. This is not possible!
She threw the covers back and got to her feet gingerly; not used to the extra weight hanging on to the front of her. Violet had to see this.
Crossing the hall to her own room, Kathleen started at the sound of thunder pealing very near their house. Her heart racing, she opened her door and entered to find Violet snoozing in the bed. Kathleen ambled over to her sister and nudged her shoulder.
“Vi, you need to get up. Something even stranger has happened.”
Violet opened her eyes slowly, smiling at her sister’s face above her, bright red hair framing her eyes.
“Whass wrong sis?” Violet spoke through a dry mouth and general sleepiness.
Kathleen stepped back and pulled up her shirt, settling her hands around her pregnant belly. At first, Violet didn’t register the change, but when she did, she sat bolt upright in bed and stared. Then she rubbed her eyes and took another look, still speechless. Meeting Kathleen’s eyes, Violet asked in a halting voice, “Did I do that?”
Kathleen shook her head in incomprehension as she stared down at her own midsection, filled with child. “No one else has ever shot their load in my vag, so yeah, It’s got to be you.”
Violet frowned and got out of bed, her dick swinging like a pendulum.
“Don’t blame me for this; there is no possible way that a baby can grow in someone overnight!”
Kathleen met her sister’s eyes again, the bond between them stark in each other’s eyes.
“It’s got to be those books, Vi. Let’s get dressed, eat something, and take a look at every book that’s hidden up there, ok?”
Violet nodded, stepping closer to her sister. “We’ll figure this out, ok?”
Kathleen nodded, and put her arms around Violet, unsure of what was happening inside her own body.
They both got dressed and met in the kitchen. After they had something to call breakfast, they proceeded into the vast library. Since Kathleen was in no condition to be climbing around, Violet climbed the ladder to the target shelf, and grabbed the next book, which had no markings on either cover. She brought it down, handed it to her sister, and went up for another one.
Looking up at Violet on the ladder, Kath could see the lengthy dick and balls swinging underneath the white skirt that Violet was wearing. A wave of arousal rose and crashed over Kathleen, more powerful than anything she had ever felt. She almost lost her balance at the incredible feeling, so she set the book on the end table and sat down in a chair. Her mind spun for a moment, but then she focused on Violet descending the ladder, and knew the cure instantly.
Violet turned and set the book on the table, and noticed Kathleen staring at her with an intense look.
“You didn’t read anything in that book did you??”
Kathleen shook her head, her eyes locked on the cock barely outlined in the crotch of Violet’s legs. “I’ve got to have you, Vi. I can’t stand it any longer; you need to fuck me good.”
Violet opened her mouth to respond, but Kath was already stripping off her pants, casting away her shirt. Her belly almost seemed bigger that when Violet last examined her sister, but that was forgotten when she saw the fluid dripping down Kathleen’s leg.
Violet raised her eyebrows at the look in Kathleen’s eye, but shrugged and dropped her skirt and began to fondle her dick. It’s got to be the hormones raging. The books can wait.
Kathleen strode over, her belly leading the way, and got to her knees, taking Violet into her mouth and sucking furiously. Saliva dripped with abandon. Kathleen’s eyes spoke of her great need, so the moment that Violet was hard enough, Kath pushed her sister onto the carpeted floor , straddled her hips, and sat down with a guttural grunt. Violet gasped at the feeling, Kathleen was a bit tighter than before, but she returned the thrusts, trying to reciprocate all the work that Kath was doing.
Every single inch of meat was being consumed by Kathleen’s vagina every time she brought her pelvis down to meet Violet’s hips, and all but the head was exposed when Kath partially stood up. Despite being very pregnant, Kath was slamming down hard every time, the look of carnal pleasure never leaving her face. She came up on an orgasm, her breaths quickening until it broke over her, pushing down on Violet’s hips and screaming for a couple seconds.
Vi was taken aback a bit by how hard Kathleen was going at her. Something was wrong here.
In between breaths, Violet tried to tell Kathleen to be careful, and that maybe a break should be taken. But Kath leaned forward, pinned Violet’s arms to the floor, and locked eyes.
“I need your cum in me.” She bit out as she fucked her sister’s cock. Her eyes looked to the side for a moment as though confused. “I don’t know why. I’m already pregnant.” She looked back into her sister’s startled eyes. “But I know I need it. Don’t spare the semen, sis.”
Violet tried to break free a couple times, but Kathleen was holding her down fast. Violet made to shrug, and started meeting Kathleen’s thrusts again.
Slowly, Violet began to feel more and more aroused, if that were even possible, since her cock was already rock-hard. It seeped into her head, and within moments, she knew that she absolutely needed to deposit as much cum as possible deep inside of Kathleen. She was slightly confused at where all of this was coming from, but it was drowned out by her need to breed her sister.
Violet broke the hold, pushed Kathleen onto her back, got on top of Kath, and pushed her cock back in. She thrust as deep and as fast as possible, until she felt the familiar feeling in her balls that meant she was about to cum. She leaned over Kathleen, meeting her eyes.
“Here you GO!”
With that last syllable, Vi thrust all the way in and physically jerked as the first rope of cum shot out of her and into her sister. Kathleen shivered as she felt the fluid splash against what felt like the bottom of her lungs. Violet pushed again at Kathleen’s crotch, spasming again as more cum was deposited within Kath’s womb. After three times, the strength of the ejaculation hadn’t subsided. Violet and Kath laid there on the floor of the library while Violet came for almost an entire minute, every shot making Violet spasm and Kath shiver at the feeling.
As the orgasm subsided, Violet kept her cock inside, and gently placed a hand on Kathleen’s belly. Both girls stared at each other, able to do nothing more than pant.
The post-orgasmic bliss subsided slowly. As it did, they each became aware of how they were both taken by their arousal, as though they weren’t in control of themselves. Violet pulled out of her sister, still astonished at how much could fit inside of Kathleen now. They both lay on their backs looking up at the high ceiling.
“Kath, we’ve got to see what else is in those books. We’ve got to make this stop, somehow.”
Kathleen nodded her assent, and made to get up. She fell back with a gasp, though, and grabbed at her belly, feeling movement inside. Violet went to her sister’s side, and watched as the baby moved around inside of Kath’s midsection, as though it were turning somersaults. This only happened for a few seconds, before subsiding as mysteriously as it began. The girls looked at each other with unease, before Vi helped Kathleen to her feet.
As they gathered around the table, Violet’s slowly shrinking dick swinging beneath her skirt, they wondered at Kathleen’s unborn child. Kathleen was sure that her belly was protruding more than it was when she got up, and she said as much.
“If you give birth today, I’ll help you, but I don’t think we should go to the hospital. They will ask far too many questions that we still don’t have the answers for.”
Violet made sense, so Kathleen agreed that it would happen here at home.
As Violet went and retrieved the last of the hidden books, Kathleen examined the covers for any other identifying marks. Only one other book had a marking on its cover, and it was the smallest book, not bound in leather like the others. As Vi rejoined her, Kath decided to take a chance and open the smaller book. Luckily, it was all in English, and handwritten as well.
The first page said what the two girls wanted to hear.
‘This booklet has been written to undo the damage anyone has wrought by reading from the Book of Rites. For nothing but damage can come from it if improperly recited.’
Thunder rumbled outside as Kathleen finished reading.
Violet turned the page and found a table of contents. “Ok,” she said, “What do we want to get rid of first?”
Kathleen held her belly with both hands, and met Vi’s eyes for a moment before speaking.
“Violet, it’s a thought that I had never considered before, having your baby. You were never able to impregnate me before! But now… Well, I don’t want anyone’s baby at this point in time. If we can get rid of it, I want to.”
Violet saw the look in her sister’s eyes. Whatever had grown between them ever since Violet had grown her cock was substantial, more than a bond and more than sisterly love. But they were both in agreement on this point; neither girl wanted a child right now. So Violet nodded.
They both turned to the page that would get rid of this unnatural pregnancy. The first line read as follows: It is important to reverse the curse before the child is born. Only grievous pain and torture follows the birth of the Unnatural. The impregnated must read the following list…
After that was a list of numbers.
Kathleen looked with wide eyes at her sister. “What the hell is inside me?”
“You better get reading that list out loud. That’s how the other curses worked.”
Kath nodded to her sister’s suggestion, and took up the booklet. She opened her mouth to speak, but was suddenly interrupted by a jolt from her midsection.
“Ahhh!”
She clutched at her belly as a good amount of fluid shot out of her vagina, puddling on the carpet. Gasping, Kath glanced at Violet in fear. “My water broke!”
Violet helped her panting sibling to the chair, and held up the booklet for her.
“You’ve got to read the numbers, Kath! The book said to do it before the baby is born!”
Kathleen grabbed the book as she blew her breaths out through her mouth. Her stomach visibly churned as the child inside turned to face head-down. Her hands shook as she tried to concentrate on the page.
Violet got down on her knees and looked at Kath’s vagina, an expression of surprise covering her face.
“Sis, you’re already dilated! Read faster!”
Kathleen started shouting the numbers aloud, her pussy gaping open around five inches. Violet stared at her sister’s vaginal walls as they pulsated and shivered.
“2! 41! 59! 58! 90! 17!”
Violet couldn’t believe her eyes as Kathleen’s belly moved, the child positioning itself to be born. She knew that Kath would not get through the list of numbers before the baby was born. So she seized the initiative.
“Keep reading no matter what!”
“78! 30! 32!”
Violet made an arrowhead with her hand, and pushed her arm into her sister, burying it halfway up to her elbow before coming up against something that resembled a sphincter, which had to be the cervix. Kathleen grunted hard as Vi entered her, and grunted with every breath afterward. As Kath read off more numbers, Violet felt her sister’s cervix begin to open.
“Come on hurry, it’s happening!”
“I KNOW IT’S COMING!” Kathleen yelled back before reading the last of the numbers on the page.
All of a sudden, Violet felt the cervix halt its opening, and reverse. The next thing that happened was Kathleen’s belly shrinking back to normal, as if there was nothing ever inside it. Violet and Kathleen were so shocked by what was happening that neither girl noticed that Violet’s arm was still within Kathleen’s guts until Kath’s vagina undilated and clenched down on Violet’s hand and wrist.
Kathleen gasped again, letting out one long exclamation as Violet slowly withdrew her hand.
The two girls sat there, panting at the ordeal. Violet looked at her arm, which was slick with Kathleen’s juices, and then looked at Kath. She smiled tiredly, and gave Vi the thumbs up.
“We did it, sis.”
Violet nodded, taking one last deep breath.
“Now let’s get your pussy back to its regular size, and then you can help me get rid of this cock.”
Kathleen nodded with the smallest amount of reluctance. It was fun while it lasted.

A half-hour later, Violet stood in the hallway outside her room, her hands down her skirt feeling herself up. It felt great to be herself again, to have a vagina again. The whole penis thing was getting a little old for her.
Kathleen mounted the crest of the stairs behind her.
“Glad to be you again?”
Vi jumped at the sound of her sister, and took her hands out of her crotch.
“Yeah! It was really weird, but now I know what it’s like to have a cock and balls. But yeah, I am glad that I got my twat back.”
Kathleen grinned and nodded, before coming up to her sister.
“Y’know Vi, just because you can’t pin me to the wall anymore doesn’t mean we can’t bang sometime.”
Violet’s mouth opened the tiniest bit at the thought. Her chest filled at the thought of her sister eating out her pussy.
Kathleen saw her sister’s reaction and leaned in, her mouth meeting Vi’s lips. They kissed passionately for a moment, before Violet drew away and stood in her room’s doorway.
“We’ll see what happens. I am still technically straight, since I like cock.”
Kath’s face dropped and she turned to go to her own room, before being stopped by Violet’s voice.
“But I do have some experimenting that I want to do. After all, change can be good!”
The sisters shared a mischievous grin.
