Emma and Jason had always been close—closer than most twins. At 19, they were mirror images of youthful perfection, sharing the same striking features from their mixed heritage: sun-kissed skin, dark wavy hair that fell in effortless waves, and piercing green eyes that sparkled with mischief. Emma was a goddess in human form—5’6″ with an hourglass figure that turned heads wherever she went. Her full, perky C-cup breasts strained against any top she wore, nipples often poking through fabric when she got excited. Her waist nipped in dramatically before flaring out to wide hips and a thick, juicy ass that jiggled with every step. Between her thighs, her pussy was a neat, shaved slit, always plump and inviting, with lips that swelled when she was turned on. Jason, her identical twin in age but opposite in build, was 6’1″ of lean muscle, broad shoulders, chiseled abs, and strong arms from years of gym sessions. His cock was his pride: a thick 7.5-inch monster, veiny and always ready, with heavy balls that churned out massive loads.
They lived in a quiet suburban house with their parents, sharing a wall between their bedrooms. One lazy evening, while their parents were downstairs watching TV, Jason was in his room jerking off to his favorite taboo—incest porn. He loved the forbidden thrill, and more often than not, his fantasies starred his own sister. Emma’s body haunted him: those massive tits bouncing, her tight cunt gripping a dick, her moans echoing as she begged for more. He’d cum buckets imagining pounding her from behind, filling her up.
That night, as he stroked his throbbing dick, he heard voices from Emma’s room next door. The walls were thin, and her door was cracked open. He became curious and crept closer, pressing his ear to the wall.
Emma was on the phone with her best friend Julia, sprawled on her bed in nothing but a tiny tank top and panties. Her legs were spread wide, one hand idly tracing circles over her mound as she chatted.
“Oh my god, Julia, you have no idea,” Emma giggled, her voice husky with arousal. “I was scrolling through Pornhub last night and ended up in the incest section again. I’m talking about those brother-sister videos. Fuck, they get me so wet. Like, the way the brother sneaks into his sister’s room and just takes her… it’s so wrong, but so hot.”
“Girl, you’re such a freak!” Julia said and laughed on the other end. “Do you actually get off to that?”
“Hell yes,” Emma admitted, her fingers slipping under her panties now, rubbing her clit slowly. “I watch them and finger my pussy until I cum so hard. And sometimes… okay, don’t judge me… I think about Jason.”
“Jason?” Julia asked. “You mean your twin brother?”
“Yep,” she replied. “My own twin brother. Imagining him coming in here, pinning me down, and fucking me senseless. His big dick stretching my cunt, pounding me until he cums all over my tits or my face. God, it’d be so filthy!”
“Emma! That’s your brother!” Julia gasped dramatically. “But damn, tell me more. Does he have a big dick? You’ve seen him in boxers, right?”
Emma moaned softly as her fingers dipped inside her slick hole.
“Yeah, I’ve accidentally walked in on him changing. It’s huge, Jules. Thick and long, with those veins… fuck, I bet it’d feel amazing splitting me open. But it’s just fantasy, you know? I’d never actually do it. Though… if he ever walked in and just fucked me, I’d probably let him. We’d both cum so hard.”
They both burst into laughter.
“You’ll go to hell for this, slut! But seriously, next time you masturbate to brother porn, record it and send it to me.”
“Deal,” Emma chuckled, pulling her fingers out glistening with her juices. “Alright, gotta go—I’m horny as fuck now.”
Jason’s heart pounded as he backed away, his cock rock-hard in his boxers, tenting obscenely. She wasn’t joking! He could hear the wetness in her voice, the way she admitted fantasizing about him. His dream girl, his sister, wanted him to fuck her. No more fantasies. He had to act. Without thinking, Jason pushed open her door hard, bursting in.
“Emma, what the fuck? Are you serious about that shit?”
Emma yelped, jumping up on her bed, her tank top riding up to expose her flat stomach and the edge of her panties. Her phone slipped, but she caught it.
“Julia! Oh my god, Jason just barged in! Hold on.”
Jason stood there in just his boxers, his massive bulge impossible to hide—the outline of his thick cock straining against the fabric, the head peeking out the leg hole.
Emma’s eyes widened, locking on his crotch.
“What the hell, Jason?” she said loudly. “Get out!”
“You were talking about me fucking you,” he said bluntly, no shame in his voice. “Incest porn, fantasizing about my dick in your pussy. If you’re serious, I can make it happen. It’s my dream too, sis. I’ve jerked off thinking about pounding your tight cunt for years.”
Emma’s face flushed crimson, but her nipples hardened visibly under her thin top, poking like diamonds. She laughed nervously, glancing at his bulge again—it was throbbing now.
“You’re crazy. It was just girl talk. Julia, I’ll call you back.”
She hung up, tossing the phone aside.
“Get out, perv,” she commanded again.
“You sure?” Jason smirked, stepping closer. “Look at you—your nipples are hard, and I bet your pussy’s soaked.”
Emma didn’t say anything; her face flushed. But he backed off, leaving the room with a wink.
“My offer stands.”
The door clicked shut, and Emma collapsed back on the bed, her heart racing.
Holy shit. He heard everything. She thought.
She thought about the bulge. It was bigger than she’d imagined. It was thick and hard, just for her. She squeezed her thighs together, feeling the dampness in her panties. All day, she couldn’t shake it. During dinner with their parents, she kept stealing glances at Jason across the table, noticing how his shirt hugged his muscles and how his gaze lingered on her cleavage.
By afternoon, she was a mess—wet and aching. She excused herself for a shower, locking the bathroom door. The hot water cascaded over her naked body, her hands roaming immediately. She soaped up her soft, fluffy tits, pinching her nipples hard, imagining Jason’s mouth on them.
“Fuck,” she whispered, one hand sliding down to her shaved pussy.
Her fingers parted her swollen lips, finding her clit engorged and sensitive. She rubbed circles, fast and rough, leaning against the tile.
“Oh god, Jason… your big dick…”
In her mind, he was there, pressing her against the wall, slamming into her. She plunged two fingers deep into her tight cunt, pumping them in and out, the water mixing with her, and juices dripping down her thighs. Her other hand mauled her tits, twisting the nipples until it hurt so good.
Faster now, three fingers stretching her hole, thumb on her clit.
“Fuck me, brother,” she moaned. “Pound my pussy!”
Emma came hard, legs shaking, a gush of girl-cum squirting out as her walls clenched around her fingers. She bit her lip to stifle the moan, riding the waves until she slumped, panting. But it wasn’t enough. The fantasy was too real now. That night, after their parents went to bed, Emma lay awake, her pussy throbbing again. She slipped out of bed in just a short silk nightie that barely covered her ass, with no panties underneath. Her bare feet padded silently to Jason’s door. She knocked softly, then pushed it open.
Jason was awake, scrolling on his phone in bed. He was lying shirtless, and his boxers were tented as usual. He sat up, eyes widening at her outfit—her hard nipples visible through the thin fabric, the hem riding up to show her smooth thighs.
“Emma? What are you…”
“Shh,” she whispered, closing the door and locking it. “Don’t say anything.”
She climbed onto his bed, straddling his lap without hesitation. Her wet pussy pressed directly against the thin cotton of his boxers, her slick lips parting around the hard ridge of his cock as she ground slowly, coating the fabric with her juices. The heat between them was electric. She could feel every vein pulsing against her clit.
“You weren’t joking earlier, were you?” she asked her brother.
“Joking about what?” He asked, even though he knew what she was talking about.
“About wanting to fuck me, dickhead!”
Jason groaned deeply, his hands sliding up her thighs to grip her bare ass cheeks, spreading them as he pulled her harder against him.
“Fuck no. I’ve been wanting this for a long time. Your body is flawless. Your tits, ass, and dripping pussy are grinding against me like a needy little slut.”
Emma leaned in, kissing him hungrily, tongues dancing messily, saliva mixing as she moaned into his mouth. She rocked her hips faster, her swollen clit dragging along his shaft through the boxers, sparks of pleasure shooting through her.
“I couldn’t stop thinking about it. All day, I was wet and masturbated in the shower, imagining your cock inside me—stretching me, ruining me,” she said that in a single breath.
Jason flipped her onto her back with ease. His strong body pinned her down as he yanked her nightie up and over her head, tossing it aside. Her massive tits spilled free, bouncing heavily, pink nipples rock-hard and begging. Jason dove in, sucking one deep into his mouth, teeth grazing the sensitive peak, and his tongue flickering furiously. His free hand cupped her dripping pussy, fingers sliding through her wet folds.
“God, sis, you’re absolutely drenched. This greedy cunt’s mine now—I’ve been dreaming of tasting it, fucking it raw.”
“Yes,” she moaned, arching into his mouth, her hands tangling in his hair. “Finger me, Jason. Feel how tight I am for my brother’s cock.”
He didn’t hesitate. Two thick fingers plunged into her velvet heat, curling perfectly to stroke her G-spot while his thumb circled her throbbing clit. Emma bucked wildly, her juices gushing around his fingers and squelching obscenely as he pumped harder. A third finger joined, stretching her wider, preparing her for his girth.
“Fuck, you’re gripping me like a vise. You’re so hot and wet. I’m gonna wreck this pussy with my dick.”
He shed his boxers, his 7.5-inch cock springing free—thick as her wrist, veiny ridges pulsing, the fat purple head glistening with precum that dripped in heavy strings. Emma stared hungrily, licking her lips.
“It’s so big,” Emma said, surprised. “It’s even bigger than in my fantasies. I need it in my mouth.”
“Suck it,” he commanded, kneeling over her face, his heavy balls dangling above her chin.
She eagerly obeyed, wrapping her soft lips around the swollen head, tongue swirling around the sensitive underside, and tasting his salty cum. She bobbed deeper, gagging as his thickness touched the back of her throat, saliva dripping down the shaft and coating his balls. Jason gripped her hair and fucked her mouth with increasing force—slow, deep thrusts that made her eyes water and her throat swell.
“Good girl, sis. Get it nice and sloppy for your cunt.”
After minutes of a messy, throat-fucking blowjob, strings of spit connected her lips to his cock when he pulled out. He flipped her onto all fours. Her perfect ass arched high, her pussy lips were puffy and glistening, and her asshole winked invitingly. He slapped her cheeks hard, leaving red handprints while hypnotically watching the flesh jiggle.
“This ass is fucking perfect. I want you to know how good it feels.”
He rubbed his slick cockhead along her slit, teasing her entrance and clit until she whimpered.
“Are you sure, Emma?” he asked, looking at his sister’s face.
“Yeah, Jason,” she said and nodded. “Fuck me as you want. Shove that dick in me—make me scream.”
He thrust in one brutal go, burying half his length in her vise-tight heat. Emma screamed into the pillow, her walls stretching painfully and deliciously around his girth, each ridge rubbing against her sensitive spots.
“Ohhh fuuuccckkkk!”
She nearly screamed, but Jason covered her mouth so their parents wouldn’t hear them.
He grabbed her hips, slamming forward until his balls slapped her clit, bottoming out deep in her cervix. Her pussy squelched lewdly with each savage thrust, creamy froth coating his shaft as he railed her relentlessly. The bed creaked dangerously, with the headboard thumping against the wall. She pushed back greedily, her massive tits swinging like pendulums, nipples grazing the sheets.
“Harder! Fuck me harder, bro!”
He reached around, pinching and rubbing her clit furiously while choking her lightly from behind. Emma’s first orgasm crashed over her—her cunt spasming wildly, squirting clear streams down his balls and thighs as she wailed.
“Cumming! Oh god, yes—your cock’s making me squirt!”
Jason pulled out with a wet pop, flipping her onto her back for missionary, not waiting for her to recover. He hooked her legs over his broad shoulders, folding her in half, her knees by her ears, and slammed back in balls-deep. The new angle let him hit deeper, bullying her cervix with every punishing thrust. Her tits bounced violently, sweat flying, eyes rolling back in ecstasy.
“Emma, look at me while I fuck you.”
“It’s so deep, and it feels like you’re in my womb!” she said, looking at him.
Jason kissed her sloppily, tongues battling, biting her lips as he drilled her mercilessly. Sweat slicked their bodies, the room reeking of sex—wet slaps, moans, and the musky scent of her arousal filling the air.
“Turn over—ride me,” he growled, lying back.
Emma straddled him. Her juicy ass cheeks spread wide as she sank down slowly, inch by throbbing inch, until she was impaled fully. As her pussy lips gripped his base, she gasped at the fullness. Then she bounced—hard, fast, her ass rippling with each drop, his dick disappearing into her creamy, frothy cunt over and over. Jason slapped her ass red, fingers digging into the flesh, pulling her down harder.
She rotated her hips in circles, then slammed up and down, her juices splashing everywhere. He sat up suddenly, wrapping one arm around her waist, the other mauling her bouncing tits—pinching, twisting, and slapping them until they glowed pink. His fingers found her clit again, rubbing viciously. Another orgasm built fast, her walls fluttering.
“Feels so good, Jason!” Emma whispered, her eyes closed. “Your cock’s hitting my deepest spots—I’m gonna cum again!”
He thrust up brutally to meet her, their bodies slapping wetly.
“I’m gonna cum soon. Where do you want my load?”
“Not inside,” she panted desperately, even as her greedy pussy clenched harder, begging for it. “Cum on my tits… or my face. Just not in my pussy—we can’t risk knocking me up.”
But Jason was lost in feral lust, hips snapping wildly. As she slammed down one final time, her cunt convulsing in a massive orgasm—squirting again, soaking his groin—he buried himself to the hilt and erupted.
“Fuck… can’t hold it! Take it all!”
“No—Jason, don’t—pull out!”
It was too late. His cock swelled, then exploded—rope after thick, hot rope of potent cum blasting directly into her womb. Pulse after endless pulse, flooding her depths until it overflowed, his balls contracting visibly as he pumped her full.
Emma gasped in shock and forbidden pleasure, feeling every hot spurt paint her insides, her body milking him greedily despite her words. The sensation triggered another aftershock orgasm. Her pussy spasmed to suck him dry.
As his cock softened slightly, still twitching out final drops, she jumped off with a wet slurp. Thick white streams of cum immediately gushed from her gaping, ruined pussy—creamy rivers dripping down her inner thighs, coating her legs in sticky trails that pooled on the floor. She grabbed her bunched nightie, holding it between her legs futilely as more leaked out.
“You’re an idiot, Jason!” Emma exclaimed in anger. “I told you to pull out!”
“I’m sorry, sis,” he apologized. “I tried, but it was too late.”
“Fuck, it’s leaking everywhere! You fucking creampied me!”
Jason watched blatantly, his almost soft cock glistening with their mixed fluids. Emma dashed to the bathroom, cum trailing down her trembling legs in obscene rivulets.
