I Seduced My Sister

I’d been obsessed with my sister since the day she got boobs. That sounds wrong, but there it is, out loud, the thing that lived in the back of my skull since age thirteen: my big sister Mia was gorgeous, wild and way out of my league even if I wasn’t related.

She had high cheekbones, full, naturally pouty lips, and those warm hazel eyes that always seemed to sparkle with mischief. Long, wavy chestnut hair that fell down her back, and a body that had filled out beautifully: full, heavy double-D tits, a narrow waist, wide hips and a thick, round, plush ass that jiggled when she walked.

It wasn’t just that she was hot, though, Christ, the first time I saw her in a bikini I nearly snapped my neck from the whiplash, but she was fun, too. She’d sneak out with me after our parents went to bed, drag me along to parties I had no business being at, call me “little bro” and “golden retriever” and still wind up letting me crash in her bed when I couldn’t sleep.

By the time I’d hit twenty and was back living at home for the summer, my “phase” had only gotten worse. It was like the universe wanted to torture me. Mia was two years older, back from state school with a body that looked genetically engineered to humiliate mine. She’d gotten even curvier, with a round, plush ass and tits that looked like a porn star’s, all packed into five and a half feet of crazy. Every morning I’d make a sandwich and watch her wander around the kitchen in a sports bra and cutoffs, pretending not to notice the way the hem chewed into her thighs or how her nipples poked through the thin cotton. It was the same story: she was always “between boyfriends,” always a little hungover, and she knew exactly how to push my buttons.

Sometimes I wondered if she did it on purpose. Not that it mattered. She was off limits and I was too scared to do anything about it, so mostly I jerked off and wrote it off as some sick personal flaw.

That all changed on a Tuesday afternoon, when I discovered what my hot ass sister actually was up to.

I was browsing Reddit in the den, dicking around on a throwaway and trawling for anything to kill the post-gym boredom. I wound up on a NSFW subreddit, half-mindedly scrolling through the usual parade of amateur thirst traps, when I saw a post that made my heart fall out of my ass.

It was a selfie. A girl on her knees in front of a mirror, wearing nothing but a pink g-string, long chestnut hair spilling over one bare tit. The face was cropped, but the rest was clear: the freckles on her chest, the lazy gold bracelet on her wrist, the birthmark above her right hip … My sister, in full HD.

I zoomed in, praying I was wrong. I even tried reverse-image search, but my stomach had already gone cold with recognition. The post was tagged with an OnlyFans link, and my hands trembled so bad I nearly clicked the wrong thing. When I found her page, I stared at the username, reading it again and again. HazelHeaven22.

I was hard in seconds. Disgusted, ashamed, but more turned on than I’d ever been in my entire life. I bought a month’s subscription before my brain could catch up with my dick.

The next hour was a fever dream. Mia’s account was loaded: solo videos, nudes, even DM pay-per-views. The stuff on her feed started mild: mirror selfies, tongue-out teases, thong and pasties, the works, but behind the paywall? It was like finding her hidden diary, except every page was written for a stranger’s erection.

In one clip, she lay in bed, topless, biting her own nipple and whispering filth to the camera. In another, she straddled a pillow and rode it until she came, moaning and cursing and using her own name. There were even some where she wore a wig and called herself mommy and I didn’t know if I should laugh, puke, or explode in my shorts.

I came twice, then sat in the dark, sweating, wondering what the fuck was wrong with me. The answer: nothing. Or maybe everything. It didn’t matter. The part of my brain that said “this is wrong” got steamrolled by the part that said “I need her.”

The rest of the week I watched everything she posted, sometimes in real time. I tried not to make it weird between us, but every time she’d wander into the living room in a towel or plop down next to me on the couch, all I could think was, “I’ve seen your pussy and you have no idea.” I almost confessed, just to see what would happen, but I held back. I needed a plan if I really wanted to seduce her.

It showed up Friday.

Our parents had taken a last-minute weekend trip, leaving us alone for seventy-two hours. Mia texted me Friday afternoon: order pizza, I’ll pay, be home at 7. I played it cool, but the entire drive back from the gym my heart was pounding out a Morse code for “today’s the day.”

When I got home, I found the pizza on the counter but no Mia. I heard faint music from upstairs and followed it up to her room, where the door was cracked just enough to see inside. She was filming content.

I froze. She had a little phone tripod set up, a ring light by the headboard. She was sitting cross-legged on her bed in an oversized tee and nothing else, legs bare, hair wild. The camera was pointed right at her, and she was giggling at something on her phone between takes.

I should have left. Any normal person would have left, but I wanted her badly. Instead, I pushed the door open and said, “Whoa, sorry, didn’t know you were—”

She flinched, then rolled her eyes. “Jesus, Jake, knock much?”

“Didn’t realize you were streaming,” I said, acting casual. I leaned in the doorway, pretending my eyes weren’t glued to the triangle of thigh showing under her shirt.

“Not streaming, recording. Get out, freak.”

I shrugged. “You want the pizza downstairs or…?”

She made a face, then reached for her shorts. “Whatever. Gimme five.”

She saw me watching, but then her mouth twitched, and she smirked. “What, you never seen a girl film TikToks?”

I let the silence hang, then, “Not like that.”

She stiffened. “Like what?”

I looked her dead in the eye. “With your tits out.”

The world held its breath. Mia’s cheeks flushed, but she didn’t look away. “That’s rich coming from a guy who walks around in his boxers all day.”

I grinned. “Touché.”

She kept staring, like she was sizing me up. Then she jerked her chin. “If you’re hungry, start without me.”

Instead of leaving, I stepped all the way in. “What’s it for?”

Mia’s eyes narrowed. “What?”

“Your video,” I said, and moved closer, close enough to see the little mole above her lip, the same one I’d seen in three different “leaked” pics this week. “You on TikTok now? Or is it—”

She cut me off. “None of your business.” She uncrossed her legs, but the hem of her shirt rode up, and I saw everything.

I couldn’t help myself. “You know you left the door open, right?”

She scoffed, but her voice was shaky. “Pervert.”

I didn’t back down. “Yeah, maybe. But you didn’t close it, either.” I put my hand on the doorknob and swung it gently, until we were both shut inside. “So what are you really filming, Mia?”

For a second, she looked like she’d throw the phone at my head. Instead, she just sighed and deflated.

“I need money, okay?” she muttered. “What’s the big deal?”

I could have pretended to buy that, but I didn’t. I pulled my own phone out, flipped it open, and held it up.

She looked at the screen, confused. Then her eyes went huge. “What the fuck?”

“I found your page,” I said. “You should really use a better username.”

She didn’t say anything, just sat there frozen, blinking. The room was dead silent except for the hum of the ring light.

“You’re not mad?” she said, finally.

“Mad? No. Shocked, yeah. Kinda turned on, too.”

She laughed, short and bitter. “You’re sick.”

“Probably,” I said, and sat on her desk chair, spinning it to face her. “But so are you.”

She bit her lip. She looked away. I watched her chest rise and fall, watched the way her hands twisted in the hem of her shirt. For a moment, neither of us moved.

“So what,” she said, voice flat, “are you gonna rat me out?”

I shook my head. “Nah. Unless you want me to.”

She scoffed. “Blackmail? Real classy.”

I shrugged. “It’s not blackmail if you want it too.”

She opened her mouth to argue, then stopped. Her legs shifted, pulling the shirt down. Her cheeks were burning. “What do you want, a hand job?”

“Nope, I want sex. I want to have sex with you badly.”

“How badly?”

“I can show you.” I stood and stripped off my shirt, then tugged at the waistband of my shorts, letting them drop just enough to show the hard-on tenting my boxers. I watched her watch me. She was biting her knuckle now, eyes locked between my legs.

“You want to?” she whispered.

“I do.”

She pulled off her shirt, leaving nothing but skin. Her full, heavy double-D breasts spilled free and jiggled beautifully, capped with small, rosy-pink nipples that were already stiff with arousal. Her pussy was plump and smooth, the outer lips puffy and glistening, her inner folds a delicate shade of pink and already wet with excitement.

I took a step forward, close enough to touch. “You’re really fucking hot,” I told her. “On camera. But even better in person.”

She giggled, then clapped her hand over her mouth like she couldn’t believe herself. Her hair fell over her shoulder, and she tossed it back, putting her whole body on display.

“You’re a perv,” she said. But her voice was shaking for different reasons now.

“I’m your perv,” I said. I reached out, giving her time to change her mind.

She didn’t. My hand found her hip, and she shivered. The next second, she was pulling me onto the bed, and my lips crashed into hers. While we were kissing, she grabbed my hair and pulled, hard, like she was punishing me for making her want this. I pushed her down, and her legs locked around my waist, nails digging into my back. Every part of her was warm, soft, and alive.

“Fuck,” she whispered, voice breaking. “We shouldn’t—”

I shut her up with another kiss, this one slower, deeper, and she melted into it. My hand slid between her thighs, and she was soaked, even more than I’d imagined. I rubbed her clit with my thumb, and she moaned so loud I thought the neighbors would call the cops.

“I’ve wanted this forever,” I whispered into her ear. “You have no idea.”

“You’re not the only one.”

Her hand found my cock and squeezed, harder than she needed to. I groaned, grinding against her, and she spread her legs wider.

“Take it out,” she begged.

I did. My dick slapped up against my stomach, leaking and angry. Her eyes went wide, like she couldn’t believe what she’d unleashed. She bit her lip again and reached out to touch, just her fingertips at first, then her whole hand, stroking the length.

“You’ve been jerking off to me, haven’t you?” she said, taunting.

“Every day.”

She smiled. “God, you’re sick.”

“You love it.”

She squeezed harder. “Yeah, I kinda do.”

I lined up at her entrance, and finally, I pushed it in, entering my sister. Mia gasped sharply, her nails digging into my shoulders as I sank into her. She was incredibly tight, hot, and wet, her pussy clinging to me like it never wanted to let go. I groaned at the feeling, the taboo of being buried balls-deep inside my own older sister hitting me like a drug. I didn’t give her time to adjust. I started fucking her with deep, dominant strokes, claiming her completely.

“Fuck, you’re so tight,” I growled, gripping her hips hard enough to bruise. “This pussy was made for me.”

Mia moaned loudly, her head falling back against the pillow. Her full breasts bounced with every thrust, her rosy nipples hard and begging for attention. I leaned down and sucked one into my mouth, biting just hard enough to make her cry out. She arched into me, her legs wrapping around my waist, pulling me deeper.

“Yes… Jake… oh god,” she whimpered, her voice breaking. “We shouldn’t… but don’t stop.”

I didn’t. I fucked her harder, slamming into her with long, powerful strokes, my hips slapping against her. The wet, obscene sounds of her pussy taking my cock filled the room. I reached down and rubbed her clit with my thumb while I pounded her, making her tremble and moan louder.

“You’re mine now,” I said. “My sister. My slut. Say it.”

“I’m your slut,” she gasped, her eyes glassy with lust. “Your dirty little sister slut.”

I pulled out, my cock coming out glistening wet, and I flipped her over onto her stomach, pulling her heart-shaped ass up so I could take her from behind. Her round, plush ass jiggled beautifully as I thrust into her again, deeper this time. I spanked her hard, leaving red handprints on her pale skin. She cried out, pushing back against me, begging for more.

“Harder, Jake… fuck your sister harder!”

I grabbed her hair, yanking her head back as I railed her. My other hand reached around to rub her clit, and I could feel her pussy clenching around me, getting closer. I spanked her again and again, the sound of my hand on her ass mixing with the wet slap of our bodies.

Her pussy started spasming around my cock. She came hard, her whole body shaking, her walls milking me as she moaned my name. The feeling pushed me over the edge. I buried myself as deep as possible and came raw inside her. Thick, powerful ropes of cum erupted from my cock, flooding her pussy in heavy waves. I kept thrusting through my orgasm, pumping every last drop deep into my sister’s womb, filling her completely until cum leaked out around my shaft and dripped down her thighs.

I stayed buried inside her for a long moment, both of us panting heavily. When I finally pulled out, a thick stream of my cum poured from her well-fucked pussy, running down between her red ass cheeks onto the sheets.

Mia collapsed forward, breathing hard, her body flushed and marked with my handprints. She looked back at me with a dazed, satisfied smile, her eyes still glassy with lust.

“Fuck… that was intense,” she whispered.

I gave her ass one last firm spank, making her whimper. “You’re mine now,” I said. “And this is only the beginning.”

She nodded weakly, still catching her breath. “Yes.”

I pulled her into my arms, holding her close as we both came down from the high. The guilt was there, burning in the back of my mind, but it was drowned out by the deep satisfaction of finally having fucked her.
