Desc: Incest Sex Story: Chapter 1: Maddi - Madison and Diana are futanari half-sisters. Sick of being minorities, they hatch a plan to impregnate teenage girls and populate the world with their kind. But when one of them becomes more radical, can the other bring her back to earth? Or will the rift break a sisterly bond and destroy their dreams?

Madison Kroeger curled her toes, about to pass the point of no return. The young futanari swiped the rogue strands of raven hair from her sweaty brow and thrusted on. Her clammy palms clutched her lover’s boney shoulders as she pressed deeper. The girl beneath her squirmed in the thick layers of silkish blankets that topped Maddi’s queen-sized bed. The girl’s commingled throaty moans accompanied the gentle squeaking of bedsprings. These sounds were faint, as neither girl weighed more than a hundred pounds. Maddi;s pants became louder-- her breath tighter. Her cock pulsed inside its prey.

“Waitwaitwaitwait...” Mary squealed, each ‘of her waits’ growing louder and panicked. She pulled herself from Maddi’s shaft and clutched her blushed-red chest. “I--I’m sorry.” Mary spoke between gasps, her skinny fingers combed through her frizzy ginger hair. “I don’t know about this Maddi.”

Maddi wore a glowing smile as she sat back. “It’s okay, Mary. I’m scared too.” Her eyes cast downward, her heart raced at the sight her veiny cock. The pulsing shaft glistened with Mary’s fuck juices. “Sex is a huge step in a relationship.” Maddi said after gulping down a dry swallow. “Still.” She smirked. “It feels amazing doesn’t it?”

Mary softened her glance, face red with embarrassment. She had to admit the sensations of her schoolmate between her legs brought her uncharted pleasure. “It feels amazing, Maddi.” Mary said. “I’m just not sure about the other thing.”

“What’s that?”

“T--the making a baby thing.” Mary could barely get the words out before clamping up. She never expected her first time to be so intense, though she HAD always assumed it would have been with a real boy-- and surely that boy would wear a condom.

“Mary,” Maddi lowered her voice as her eyes drank in Mary’s emaciated form. The girl’s ribs poked behind her freckled skin. From her soft, flushed face to the sparse wisp of red covering her mound-- it was all Maddi could do to keep from drooling. “Mary, I love you.” She searched through the layers of blanket for Mary’s trembling hand and pulled to her throbbing chest. “Do you feel how hard this throbs for you?” She kissed the back of Mary’s hand and linked their fingers. “It will be okay-- whatever you decide.”

Mary stared through Maddi as she pondered. Her chest heaved while the gears in her head clicked away. It was a split second that seemed endless. She sat up on her knees and mashed her skinny legs together and it felt the wetness that soaked her newly deflowered pussy. The pressure sent a sinful gush of pleasure to her middle. It was enough of an adrenaline rush to put her over the edge.

“Baby!” Maddi cooed when Mary wrapped her trembling fingers around her shaft. Mary guided the it back between her legs as she reclined. Maddi resumed her quick, darting thrusts. Her long straight hair dangled and draped across Mary’s tender breasts, covering the erect nipples raised high. Maddi lost herself in carnal pleasure-- Mary’s tight pussy gripped her quivering member like the virgin vise it was. “Nnngh!” Maddi squeezed a high-pitched whine from her throat as her throbbing balls tingled. Her swollen futa-jewels slapped against Mary’s hairless ass and made a loud, wet noise. The end was nigh.

Mary’s face turned bright red. Her hands raced to cover her mouth. Whether from instinct or embarrassment, Mary clamped them over her lips just before her cheeks ballooned to contain her scream. Her legs kicked, then shot out, then stiffened. Her core shook while her first orgasm ravaged her body. Her eyes rolled back as she crashed back to the bed, letting out a throaty groan. Mary’s lungs continued to heave, boney rib cage rising and falling in dramatic fashion. Her sight came to focus on Maddi’s grimacing face as she wondered to herself. ‘Oh my god. Is she about to come? Will I know? Am I going to feel it?

Mary’s eyes shot wide-open as her questions answered themselves. Yes, Maddi was coming. Yes, she could feel Maddi’s cock spasm inside her-- the warm sticky fluid flooded her after Maddi have one last satisfying ball-draining grunt. Mary kept her hands fastened over her mouth as she as her womb filled. “Oh my god...” The thoughts shot through her head while she muffled her gasps. “There was no turning back now. I’m all hers...”

Maddi collapsed on top of Mary with a thud. The room was silent other than the girl’s commingled pants as they caught their breath. Maddi peeled herself from Mary’s torrid, filmy skin a few minutes later. Her wilted cock slid from its conquest, soon followed by a steady pour of thick seed from Mary’s flower.

“Oh my gosh!” Mary cried as she examined her leaking slit. “It’s getting on the bed!” The flow was thick and creamy as it pooled under her boney ass.

“Hey Mary!” Maddi tried to calm her shamed partner. She licked her lips and placed her hands on Mary’s emaciated hips. “It’s just a little cum.” She smiled with a jocular tone. “It’ll come out in the wash I’m sure.”

Mary gave a heavy sigh. She rested her hand across her reddened chest and seemed to look much more at ease even though she shivered. “Okay, Maddi.” She closed her eyes and smiled. “Sorry, I get so nervous sometimes.”

“That’s okay, baby.” Maddi kissed the girl squarely on the lips. “I’m just glad you enjoyed yourself. Didn’t you say there’s a recital tonight you have to prep for?”

Mary’s eyes bugged open. “Yes! You’re right. Oh my gosh, I have to go.” She scooted to the edge of the king size bed and recollected her clothes. “Maddi, you’re coming to see me tonight-- right?” She asked with great nervousness, her fingers trailed down her flat tummy to fondle the damp wisps between her legs.

Maddi stretched out and kicked her legs. “Of course, baby. I wouldn’t miss it for the world. Love you.”

“I love you, too.” Mary said. She rolled up her pair of cotton white panties and a damp spot quickly formed in the crotch. “I’ll be thinking of you.”

Maddi giggled and tossed her head back. “You should! Considering how much of me you’ve got in you!”

Mary gave one last nervous smile from over her shoulder as she closed the door gently behind her.


Maddi was soon left alone with her thoughts. Still naked on her bed, the young girl’s eyes noticed the puddle of her jism just before it finished soaking into the comforter. Her skinny fingers dalloped up a few drips and she brought the stickiness to her nose. “Funny...” She whispered to herself, smelling the bleach-y scent of her cum. “How crazy this little bit of fluid makes me.” She smirked. “I’m such a different person when you’re out of me.” Mary’s sweaty stench still clung to her body. She cracked another smile as it wafted up her nose. “She hasn’t quite gotten the hang of the deodorant thing. Not that I mind.” Maddi could barely make out the faint scent of her lover’s weak, failed teenage perfume. “Maybe I should take a shower.”

She looked over her shoulder as her cell phone rumbled across her nightstand. Maddi rolled over the wet spot and snatched the phone, sliding her fingers along the screen. “Hello? Maddi Kroeger.” She chirped. “Savannah? How are you love?”

“Maddi,” Her friend’s solemn voice blared through the speaker. “I need to talk to you.”

Maddi sat up with a devilish smirk on her face. “Yes, dear?”

“I’m pregnant.”

“Oh,” Maddi leapt to her feet and pranced to her desk and vanity. “Oh my god, Savannah. What are we going to do?”

“I-- I guess I’m having a baby.”

Maddi feigned a long sigh as she sat down and flipped through a notebook. She quickly found Savannah’s name on a list of 20 girls and placed a checkmark by it. “Honey,” Maddi breathed in a low monotone voice. “I know we’re young. But you know my family is wealthy. I intend to take care of you and our baby. I love you, Savannah.”

“Thank you so much, Maddi.” Savannah sniffled. “I love you too.”

Maddi ended the call and pumped her fist. She dialed another number and raced back to her bed, leaping into the middle of the covers with glee. “Diana?” She greeted. “It’s done.”

“I’m listening.” Diana Hart replied in a monotone voice and she sat on her bathroom floor waiting for her half-sister’s update.

“Savannah Richards just confirmed.” Maddi rolled over her back and pulled her knees in. “And from what I did to Mary Travers this afternoon, I can imagine her reporting positive in a few weeks.”

“We don’t deal in projections, Maddi.” Diana spat, disgusted with her sister’s perkiness. “What makes you so sure Savannah won’t abort?”

Maddi giggled. “Because unlike you I pick my marks carefully. There’s no way that pastor’s daughter will abort. All you have to do is hunt near churches. Then again, you’d probably spontaneously combust if you set foot in one.” She broke into a cackle.

“Oh, fucking hilarious.” Diana rolled her eyes. “So let’s say we preemptively award you Mary. That means we’d be tied once again.”

Maddi could hardly contain her glee. “You’re getting soft, sis. I think I’ll take the lead--” She paused as her eyes sharpened. “What was that?”

“What was what?” Diana snickered.

“That!” Maddi heard the faint sounds the retching and a toilet flushing. She sat up-- concerned. “What’s going on over there?”

“Oh, that’s just Christy. She’s a little sick.” Diana snickered again.

Maddi’s heart dropped. “Sick-- like-- morning sickness?”

“Yeeeeah.” She said. “Our playing doctor got a little out of control.”

It was clear as a whistle. Maddi had heard the hacking cough of Diana’s older sister. It was high-pitched, panicked, scared. She knew the gross sound well, having rubbed the back of many girls as they spilled their guts in porcelain. Between her Diana, she estimated siring 20 young girls from across the country. Their primal competition was now in its 6th month, and Maddi found herself losing the perverse game at a score of 11 girls to 9. If her swimmers did their job, Mary would be frantically calling in a few weeks and she could close the gap.

But something about the way Diana went about it gave Madison reason to pause. She laid in silence for a while, envisioning Diana sneaking into Christy’s room, crawling in her bed and seducing her. It gave her dull, sick feeling in her stomach. Somehow, the deal did not sit well.
