Work Text:
Alison was heavily pregnant. Everyone in the apartment was glad for her. Though she was still in college, she had been having regular sex with Jade, until Jade ended up putting a baby inside her. Eight months had passed, and Alison was heavily pregnant. Her belly was bloated, with an inverted navel and a dark line running down to where her pubic hair grew in. Her hair had become wilder and thicker since the start of her pregnancy, around her cock and her pussy. She was asking Jade for sex several times a day, and when Jade couldn’t satisfy her needs, she was fapping.
Today, Alison was jerking again, next to her brother Alice. He resembled her in many ways, including the shape and size of his cock. However, Alice wasn’t a futa. He was a boy, but his beauty had won him many admirers. He had male friends he was close to, and told them that they could use him if they wanted, and he had a secret lover. He was most popular among his sister’s futanari friends. He had sucked them off and let them stick their cocks up his ass, all of them enjoying the chance to experience his tender asshole and huge cock.
Of all the futas around him, there was none that he was more familiar with than his own sister. They had been there to see each other’s first ejaculation, and taken each other’s virginity. Alison encouraged her brother in his crossdressing, as long as he let her play with his huge cock every once in a while. When neither of them could sleep, they spent the night side by side in bed, stroking their cocks together until they spurted hot loads of cum over each other, and helped lick each other clean. There was always a lot to clean up, sliding down to their balls and in Alison’s case, her pussy. Alice was the one who harbored these one-sided feelings for his sister, and they had never gone away, even after he found himself someone to go steady with.
As Alison’s pregnancy went on, it brought back memories for Alice. When Alison got turned on too much, her breasts spontaneously lactated. She had never been pregnant until now, and Dr. Iris had said there was nothing wrong with her. She was as healthy as a futanari could be. Her breasts leaking milk from arousal was normal, and as long as she kept her milk from building up, then it shouldn’t cause any problems. Everyone who had gone out with Alison had drunk her milk, but Alice was the first. He could still recall the sweet taste of his sister’s breast milk, the way it slid down his throat and his cock, making him hard and cumming over and over again. Now that she was pregnant and expected to lactate, her milk flow was even stronger than before, staining her clothes and running down her pregnant belly. The only difference was that her nipples had gone from a youthful pink to a maternal shade of dark brown, bordering on black.
“Every time I rub one out, the baby starts kicking,” Alison said. “I’ve been so horny since I got pregnant. It’s like my cock’s hard all the time.”
“Seeing you become so maternal has made me hard, too,” Alice said.
“Your pregnant sister is getting you hard? I knew you were a perverted big brother, but that’s a new level even for you,” Alison said. “My hand’s too tired to jerk off again. Can you soothe my cock... with your mouth?”
“I was waiting for you to ask that,” Alice said.
Alice opened his mouth. A wet, slurping sound followed. Alison closed her eyes, groaning in pleasure as breast milk leaked from her tits, staining the front of her shirt with two big, white splotches. Alison lifted her shirt. Her breasts were fully revealed. She was producing as much breast milk as cock milk these days, and Jade loved drinking both. Her white, mildly sweet milk dripped onto Alice’s head, making his hair shine with the fat in her breast milk. Alice didn’t notice. He had already taken all of Alison’s huge cock into his mouth, shoving it back to his throat.
Their shared bedroom reverberated with the sound of Alice slurping on his sister’s cock. That it was his sister’s cock made him want to suck it more. The dick of the sister he had grown up with, masturbated with, and occasionally had sex with was now moving up and down, becoming covered in a film of his saliva. With each flick of his tongue, more precum leaked from her tip and into Alice’s throat, coating it to prepare for the eventual orgasm. Alice moved his head upward, stopping short of the tip. He swirled his tongue underneath the glans. The most sensitive part of the cock, for a man or a futa, and Alice understood how good it felt when he licked there.
While Alice licked, his own fat cock had grown long and hard. Using one hand to grip Alison’s cock, he stroked his dick with the other. Alice pulled back on his foreskin, exposing the head of his cock as he sucked. Sweat and smegma appeared around the tip, sending the smell of his dick upwards to greet Alison’s nose. Alison was playing with her breast in one hand while stroking her pregnant belly with the other. She had grown so big and round that her belly was obscuring her brother’s face, leaving only his long hair and perky butt showing beneath her. She heard and felt every slurp of his tongue as he explored the length of her throbbing cock.
Sucking on his sister’s cock while her large and heavy balls rubbed up against his face pleased Alice. Futa cocks were larger on average, and his sister and her friends had some impressively huge dicks. Alice’s own cock was rubbing against the sheets of Alison’s bed. The soft fabric caressed the underside of his glans, making his precum leak out while a stray hair from his scrotum disappeared into the bed sheets. His balls, packed full of cum and eager to be released, squished against the bed as he sucked, humping the bed that smelled like his sister like it was her. That chance was going to come soon enough. Alison’s cock was nearing orgasm, and the musky smell of her pregnant dick intensified inside Alice’s nose.
“I’m cumming... swallow it all,” Alison said.
Alison’s thick and creamy semen, dense with sperm and gooey in texture, went down Alice’s throat and into his stomach. Alison saw each gulp as he diligently swallowed her cum, pleasing his sister and not wasting a drop. The cum was so thick and plentiful that he saw it going up her shaft before spraying out of her tip. It kept coming in short spurts, filling his cheeks and lasting just long enough inside his mouth for him to savor it. Alice hadn’t had anything to eat since breakfast, and he was craving his sister’s cum. A futanari’s loads could be very large, enough to make a condom burst and a stomach bloat. With loud gulps, Alice swallowed each and every drop until it was no longer shooting, but still hard inside his mouth.
Alice wanted to cum badly. His cock was on edge from his hand and the bed sheets touching it, making him about to blow. Alison was aware that she could make him do whatever she wanted. She slid down the pillows, rubbing her cock until it was standing straight up in the air. The straight, rigid line of her stiff cock contrasted with the curves of her pregnant belly and her swollen breasts. She lifted her balls to show him her pussy. The juicy reward that was waiting for him at the end of their wild sex. Alison shook her cock in her brother’s direction, splashing him in the face with flecks of her hot cum. Alice spread his legs and straddled his sister.
When he stood over her like this, she was aware of just how curvy his butt was. He had a soft, feminine butt that could be mistaken for a girls’, and sometimes had, much to the confusion of his guy friends. His cock twitched while Alice placed his hands on his soft butt cheeks, spreading them apart to prepare his hairy asshole for being penetrated. The tip of his sister’s cock rubbed against his anus. He could feel the lingering traces of its shape inside his mouth, along with the mildly salty aftertaste of her cum. The glans widened Alice’s asshole, sliding into him with a wet sound. Alice closed his eyes, and a blush crossed his face.
Alison’s long, fat cock slid up into his butthole, brushing past his prostate on the way in. Alice put one hand on his nipple and rubbed his cock in the other. He had been rock hard the whole time, and wanted to keep his erection going until the end. His hips slid further down Alison’s member, moving lower until his ass was touching her thighs. Alice’s cock bounced when he reached the base. He had taken all of Alison’s cock inside him for the first time in a while. His sensitive asshole tightened around her shaft, trapping her in the warm, narrow confines of his backdoor. When his butt squeezed around her, Alison’s breasts squirted out fountains of milk.
“Even after my friends have had their way with your ass, it’s still so tight,” said Alison. She extended her arms outward, wrapping them around her brother’s butt and squeezing in on his cheeks. Alice’s cock excitedly bounced up and down in front of her. Alice raised his hips, exposing Alison’s dick before slamming back down onto it with a wet sound. Alice tried to stifle his moans, not wanting to alert the others in their apartment to their sex. Alison’s cock had returned to its full hardness, throbbing inside his boy hole with each rising and falling motion from his hips. Alice’s cock was so long that Alison wondered if she could lean forward and lick it now.
“I love your cock so much,” Alice said. “My butt...”
“Seeing my big brother at the mercy of my cock is so fucking hot,” Alison said, letting his dick beat against her pregnant belly like a taut drum. “You’re not cumming until I say so.”
“I’ll do whatever you say...” Alice groaned.
Alice’s hard cock and heavy balls bounced as he rode on top of his sister’s dick. He took his hands off, letting it freely bounce. The lights shining overhead in their shared bedroom cast the shadow of his cock across her belly. The length of his dick was such that the tip of his shadow was coming up to underneath her milky boobs. With each repeated thrust into his tender asshole, more milk leaked down from Alison’s tits, filling the room with a sweet perfume. The combined sweat and cum of the siblings mixed together, making the bedroom thick with the smell of sex.
“Sis, do you think we should tell the others we’re fucking?” asked Alice, his words slipping out between bouncing on his sister’s cock.
“How do you think they’d react?” asked Alison.
“Tasha and Karen are doing each other all the time. What’s one more incestuous pair of siblings?” said Alice. “Oh god, my ass...”
“We can tell them when I’m closer to giving birth,” said Alison. “They already know it’s Jade’s, it’s not like they’d think you knocked me up.”
Hearing his sister say those words, and having them echo in his ear, made Alice’s cock leak precum onto his sister’s belly. The clear drop landed on her inverted navel, rolling down and mixing with her sweat. He was happy that Jade, who Alison had such a good relationship with, had been the one to give her a baby. There was a part of him that wanted to do the same. He loved his sister in a way that went beyond normal sibling relationships. Even imagining that baby in her belly belonged to him made his cock want to desperately blow.
“Let me cum,” Alice said.
“Since you asked nicely,” Alison said. She squeezed her fingers down into his ass flesh, and thrust her hips upward. His butt was rubbing against her balls, nad his balls were rubbing against her thighs. With the cockhead buried deep inside his ass, Alison’s throbbing cock exploded with her second load of the evening. It was as thick and gooey as her first load, clinging to Alice’s anal walls and bubbling back out of his ass. Alice’s cock couldn’t hold on any longer, and finally blew. He had been saving it up for days to have sex with his sister. Releasing it in a large, ropey spurt felt incredible, making his balls shake.
His cum audibly shot out with a gloppy sound, flying through the air like a wet projectile and splatting against his sister’s face. It rolled down her nose and onto her cheeks, while the next ropes covered her tits and her belly. The warm stickiness of it clung to her skin, and every time she breathed, she smelled the scent of her brother’s cum on her. Alison wiped it off her face and licked it from her fingers. The white cum mixed with her milk, rolling down her body and leaving a milky trail behind. Her cock slipped out of Alice’s butt. It was shimmering and wet, soaked in her cum and her brother’s sweat. Alice’s cock was only half-hard, though he wanted to take a moment to recover. The strength of his orgasm had been so strong that it left his head feeling fuzzy.
Sweat dripped down Alice’s body, sliding off the tip of his cock and onto his sister’s stomach. He slid down onto the bed, rubbing his cock against Alison’s. Putting them side by side, their almost similar lengths and girths were made apparent. Alison, with her hand covered in breast milk, wrapped her hand around hers and Alice’s dicks. She slid down to the base, covering their cocks in a film of cum and milk. They felt the blood pumping through their dicks as they became hard once more. Standing at full size and full hardness, their tips glistened like jewels. Alice’s was still pink, while Alison’s had darkened in color like her nipples, becoming a shade of reddish-brown. Their balls squished together as Alice moved his hips, continuing to grind his cock against his sister’s.
“We haven’t done this in years,” Alison said. “My pussy’s been feeling so needy. If I don’t get fucked, I’ll go crazy.”
“Are we taking it there?” asked Alice.
“I want my brother’s cock in my pregnant pussy,” Alison said seductively.
She got on all fours and bent over. Alison raised her ass in the air, showing her brother her hairy pussy and asshole. Her cock dangled down like the pendulum of a clock, throbbing and drawing her brother towards her. From this view, her pussy was clear. Her lower lips had puffed up and her clit was rubbing against her scrotum. Bubbling, sticky love juice spilled out of her slit and back onto her balls. Her leaking breasts rubbed against the soft fabric, staining the already wet fabric with her milk. Her heavy belly hovered above the bed.
Alice pressed the length of his cock against his sister’s wet slit. HIs cockhead passed over her scrotum before poking against her pussy. She was so wet that he could go right in. Alice pushed his dick inside her. First the head entered, and then the rest of it was sucked in. The familiar feeling of Alison’s pussy tightened around his member, squeezing down on the shaft until he couldn’t pull out. His glans slid down her pussy, being caressed by her vaginal folds on every side. HIs long, hard dick stopped just short of her womb, where the child created between her and Jade was growing, with a few more weeks to go until its due date. Alice was going to be an uncle, but for now, he was acting as Alison’s lover. He pulled his cock back up and slid it back in, listening to the squelching sounds of her pussy.
Alison’s pussy had gotten tighter and hotter since she became pregnant. The extra weight from the baby in her belly pressing down on his cock was incredible. Alice stroked his sister’s belly, running his hand down the dark line that stared at her navel. He moved his cock in and out of her pussy, finding a steady rhythm as their moans overlapped. His high pitched voice and her growls harmonized together, with the kind of closeness only a brother and sister could have. Alice’s hand continued downward, sliding across his sister’s milk-soaked cock before gently grabbing her balls, fondling them in his hand and listening for her reaction.
“My brother’s cock... I love it,” Alison moaned. She felt the baby kicking in her stomach, and more milk spurted out of stiff, darkened nipples. “The baby likes it too.”
Alice saw his sister’s breasts swaying beneath her on the bed, sending drops of milk flying in every direction. Her cock bounced like his own had been only a few minutes prior, and the vibrations he was sending through her body made it all the way to her ass. Alice’s hands moved back upward. The curves of her pregnant belly were made slippery with her milk. The milk was still fresh and warm, making it difficult for him to get a grip. His palms covered in milk, Alice kept moving upward. He reached Alison’s breasts, and wrapped his hand around her tits. They were plumper than before, having gained two whole cup sizes during pregnancy.
His cock was now covered in a film of love juice. Alice humped his sister like an animal in heat, giving into this rare chance to live out his most taboo desires. Neither of them needed to speak to each other. They communicated with their bodies, telling the other how they felt through their crotches. Alice squeezed down on Alison’s breasts. Twin streams of white milk shot out, spraying off the edge of the bed and onto the floor. Alice turned his sister’s breast upward, aiming the tip of her nipple towards her face. Alison opened her mouth, letting her brother squirt her a serving of her own.
She gulped it down, and her pussy tightened further around him. Alice repeated it with her other breast. Alison licked her lips. “Tasty,” she said.
“Have you tried your own before?” asked Alice.
“My milk or my cum?” asked Alison.
“Both,” Alice said. “It’s easier to eat it after fapping.”
“Yeah... I’ve done the same,” said Alison. They knew they were siblings. Alice picked up the pace of his thrusts, going harder into his sister’s pussy. She could take it. His cock, still sensitive after blowing a load on her face, was aching for release. Alison clenched her pussy, tightening her entrance around him when the tip of his cock was near her womb. Alice held tightly onto her butt, and his balls tensed up. A second load was on the way, heading directly into her pussy.
Her brother’s cum filled her pussy, surging into it and seeping into her folds. It flowed back out of her slit, dripping down onto her balls. Alice stayed inside her until every last drop had been emptied. He gently smacked her ass. Alison’s pussy squirted upward, covering his chest in a bubbling film of her squirt. Alice’s cock softened and rested against her balls, leaking the last drops of cum down her back. Alison and Alice were covered in sweat. They needed to shower, and gave each other a look that said it would be easier to shower together. As the sweat dried and cooled down their bodies, they looked into each others’ eyes.
Alice rested his head on Alison’s lap. Her dripping breasts were just above his head. He raised his head upward, latching onto one of her breasts and sucking. The milk flowed from her nipple, going down his throat and filling his stomach with the nostalgic taste. He swirled his tongue around the bumps on her areola, sucking out every drop that flowed. Her milk dripped down his chin, covering his chest until his cock was standing upright once more. Alison jerked his cock between her fingers, moving up and down in a steady motion to keep him hard. His cum covered her fingers. Alison’s stomach growled. She was feeling hungry, and a snack was waiting fo her there.
Alison lowered her head towards her brother’s big cock and wrapped her lips around his shaft. She sucked out the last drops of cum. The taste of her pussy juice and the mild saltiness of sweat for flavor had been mixed in. She pulled her lips away from him when nothing more was coming out, and slurped up the last rope of cum that hung from her lips.
Their shared apartment only had one bathroom. Everyone who lived there had seen everyone else naked. Alison and Alice saw nothing wrong with leaving their bedroom and heading towards the shower in the nude, their cocks swinging as they went. Cum dripped out of Alison’s pussy and Alice’s butthole. It ran down their legs, stopping just short of leaving a trail of semen footprints as they made their way to the bathroom. Natasha, who’d had sex with both of them in the past, was sitting on the couch sucking her own enormous cock.
She took her cock out of her mouth and turned to the two of them, giving them a knowing look. “I thought you two were like that. I heard you going at it and I had to get myself off.”
“I don’t think we need to tell everyone,” Alice said.
“They already know,” Alison said sheepishly.
Alice was the happiest of all. Knowing that Natasha had been sucking herself to their lovemaking, his cock began to erect once again. Alison realized they were going to be in the shower for longer than she thought. All she hoped was that the hot water wouldn’t run out.
