Skip to content It was summer break, I was nineteen, and I was staying at my mother’s place. I woke up to sheets tented by the most obscene morning wood of my life while someone down the hall made sounds like they’re drowning in a porn audition. And that someone had to be my older sister, Alexandra.
The first thing I noticed was the dull, desperate throb from my cock, so hard it might have cut the mattress if it tried. Next, the porn noise. It came in wet pulses, each one interrupted by a sharp gag, then a stringy, “hhuurrgh, hhck—” like whoever was doing it was half-committed to asphyxiation. I lay there a minute, paralyzed, listening. Was it a dream? An animal dying in the crawlspace? Or was my sister really that horny?
I sat up. The tent in my boxers was so aggressive that it was embarrassing. The noises didn’t stop. If anything, they got louder and faster. The rhythm of it was quite hot: a thick, squelchy glide, a hollow clack, a gag and a wet cough, then a chorus of moans that could not be coming from a human. I wanted to ignore it, but my body was on autopilot, every cell magnetized to the promise of something filthy. I swung my feet over the side, feeling the brush of cold air against my skin, and followed the sounds down the hall.
The door to Alexandra’s room was cracked just enough for me to see in, but not enough for her to notice me. The sight froze me in place.
She was kneeling on her bed, legs folded under her, wearing nothing but a pair of powder-blue sleep shorts and a white tank top that was so thin it showed every line and curve. Her auburn hair spilled down her back and over her shoulders, framing her face. She was holding a neon-pink dildo, which was indeed huge, veiny, comically real, and forcing it without mercy into her mouth.
And not just into her mouth. She was jamming it down her throat, both hands on the shaft, eyes squeezed shut as she pushed harder and harder, until she choked and the end slammed into her lips. Thick spit dripped down her chin and over her knuckles, soaking the tank top and leaving a glossy trail down her chest. Every time she gagged, her back arched and her thighs flexed, like she was riding out the pain and the pleasure together.
There was a laptop propped on her pillow, a video playing. I couldn’t see the screen, but the audio was all shuddering, porn-star groans and muffled, desperate cheering, “Take it deeper, slut. All the way. Yes, choke on it.”
My dick throbbed so hard I almost groaned. I should have turned away … should have pretended I hadn’t just watched my own sister throat a dildo like her life depended on it, but I couldn’t. I was rooted to the spot, hypnotized by the way she kept going, never giving up, even as tears leaked down her cheeks and spit poured in rivers over her lips. I barely noticed my hand drifting under the waistband of my shorts, just enough to free myself and stroke once.
Suddenly, her eyes snapped open. She saw me instantly. She let the dildo slide halfway out, lips stretched wide and glistening, and then jammed it back in, hard. Only when she finished the next punishing stroke did she pull off, trailing spit and gasping for air, before fixing me with a look.
My older sister was twenty one, but she had always been a bombshell. She’d been turning heads since high school with those sexy green eyes. Her face was a perfect heart shape with high cheekbones that looked super cute. Even with mascara smudged beneath her eyes from tearing up during her deepthroating practice, she looked like she belonged on a magazine cover.
But my eyes betrayed me further, drifting down to where her tank top clung to her breasts. They were full and round, her nipples visibly hard through the white fabric now partially transparent from her spit. I’d caught glimpses before, walking past the bathroom, or when she’d bend over in those low-cut tops she favored, but I’d never allowed myself to stare like this.
“Oops,” she said. “Didn’t see you there, little brother.”
I yanked my hand out of my boxers. “What the fuck, Alexandra? Are you … did you—” Words failed me.
She just giggled, wiping her mouth with the back of her hand, then licked a glob of spit off her thumb. “Relax. I’m just practicing.”
“For what, the world’s least family-friendly talent show?”
“Ha! No, dumbass. Pornhub tutorial said I have to desensitize my gag reflex.” She twirled the dildo between her fingers like a baton. “Gotta be able to take it all. Guys love that.”
I stared at her. “You’re nuts.”
“Nope … but I do love them.”
I rolled my eyes.
She grinned. “Wanna watch me try again?”
“Fuck no.” I slammed the door and stumbled back to my room, blood hammering in my ears and cock so hard it hurt. I collapsed onto my bed and pulled the pillow over my head, desperate to suffocate the image of my own sister choking herself for fun. But all I could see was her green, sexy eyes locked on mine as she dared me to say anything.

Breakfast was worse. Alexandra was already at the table when I wandered in, phone propped up against a mug, earbuds in. She wore a different tank top, black this time, but just as thin, and the same tiny shorts. She also wore a bold, red lipstick that didn’t help my forbidden fantasies. She didn’t look up when I sat across from her. She was too busy double-tapping through what looked like an endless playlist of blowjob tutorials.
I tried to pour cereal and focus on the bowl. I failed.
From her phone, a girl moaned, “Fuck, that’s deep…” Then a sharp, sticky slurp, and another girl, “He’s gonna cum so hard in your throat—”
Alexandra yanked out one earbud and stuck out her tongue at me. “Don’t be so uptight, Alex. It’s educational.”
I kept my eyes on my cereal. “You’re watching porn at breakfast.”
She rolled her eyes. “It’s not porn, it’s a how-to. There’s a difference.”
“Yeah, about as much difference as a murder documentary and a snuff film.”
She laughed. “Chill, it’s not like I’m gonna start blowing random guys on the kitchen table.”
“Thank God.”
“But if you ever want to try it out…” She wiggled her eyebrows.
I almost spat milk across the table. “Jesus, Alexandra. That’s not funny.”
She put her hand to her chest, covering her cleavage, in mock shock. “Why? You’re nineteen, right? College freshman, big man on campus, still gets hard every time a girl looks at him?”
“Shut up.”
She smirked, sipped her juice, and then, because apparently there was no boundary she wouldn’t cross, she stretched her bare foot out under the table and started rubbing it up the inside of my calf.
My entire body tensed. “What are you doing?”
She didn’t stop. She just dragged her foot higher, all the way up to my thigh, then gently pressed against my crotch. The pressure was warm. She could obviously feel how hard I was, and instead of pulling away, she pressed harder, toes flexing in little teasing circles.
“Holy shit, are you really getting hard right now?” she whispered, loud enough for only me. “That’s adorable.”
I wanted to die, or cum, or both. I slammed my knees together, trapping her foot, but she just giggled and twisted, pinching my shaft between her big toe and the ball of her foot, slowly stroking up and down. She never took her eyes off the phone, as if she could do this in her sleep.
I gritted my teeth. “Can you please stop?”
“Can you please admit you love it? You’re so stiff… I can feel how hard you are already.”
“Alexandra…”
She relented, finally, but not before giving my cock one last, lingering squeeze with her toes. She pulled her leg back and went right on watching her video, face bright and innocent.
I stared at the kitchen tile, willing my erection to go away before I stood up. It didn’t.
*****
We didn’t talk for an hour after that. I escaped to the living room and tried to lose myself in video games, but I couldn’t stop thinking of her: Alexandra’s mouth wide open around that fake cock, her tongue licking spit off her chin and the feeling of her bare foot pressing against me. It didn’t help that every few minutes, she’d walk through in another revealing outfit, once in tight gym shorts showing off a subtle camel toe, and then in an old tee that hung off her shoulder and barely covered her ass. Each time, she’d glance at my lap and smirk, knowing damn well she was the reason I kept a throw pillow handy.
By noon, I was at my breaking point. I was on the couch, controller limp in my hands, when Alexandra dropped down beside me. She landed closer than normal, thigh pressed against mine, and tucked her legs under her.
“I was thinking,” she said, in her honeyed voice, “maybe I could practice on you instead of that toy.”
I laughed, not sure if I was supposed to be terrified or turned on. “You’re insane.”
She cocked her head. “You’d be helping me. I need to practice with a real one. It’s only fair.”
“You’re my sister.”
She rolled her eyes. “So? It’s not like you haven’t thought about it.”
“Bullshit.”
She leaned in, breath hot in my ear. “Liar … I saw your face this morning. And you’re not exactly hiding your boners.”
My face went nuclear. “It’s just, I mean … it’s not my fault—”
She put a finger to my lips. “Shh, just say yes.” She straddled my lap, her ass settling down on my thighs, and I felt my cock leap to attention, instantly pressed against her. She grinned, reached between us, and stroked me through my shorts.
I tried to protest, but my body was molten, every nerve raw and exposed. “Alexandra, this is so fucked—”
She kissed me, hard. Not a sisterly peck, but a deep, open-mouthed kiss, her tongue slipping between my lips, and I kissed her back before my brain even registered it.
She broke the kiss and pulled away, face flushed, eyes bright and wild. “I’ll be gentle… at first.”
She dropped off my lap, onto her knees on the carpet, and tugged at the waistband of my shorts. I hesitated, but she gave me a look that made it clear she wouldn’t be taking no for an answer. “C’mon, Alex. I want to see if I’m really getting better.”
I yielded, and I lifted my hips. She yanked the shorts and boxers down together, freeing my cock, which sprang out and slapped against my stomach. She whistled. “Holy shit. You’re even thicker than the dildo.”
I arched an eyebrow. “You’ve actually measured them?”
She grinned. “Of course. I’m thorough.” She wrapped her hand around the base of my cock and squeezed, then stroked it slowly, watching the skin stretch and shift with each motion. “So fucking hot,” she murmured, almost to herself.
Then she licked the tip, flicking her tongue over the slit. I almost came right then. She giggled, eyes locked on mine, and then took the head into her mouth, lips soft and warm. She bobbed slowly, easing down an inch at a time, her hand stroking the rest. It was already better than anything I’d felt in my life.
She pulled off, gasping, a strand of spit linking her lips to my cock. “How’s my technique?”
“It’s, fuck, it’s amazing.”
“Good. Let’s see how much I can take.” She grabbed the base with both hands and angled my cock straight at her mouth, then dove down, forcing herself deeper than before. She gagged, coughed, and pulled off, face red and eyes streaming, but then she went right back, and I told myself not to fight it, but enjoy every single second of this.
Alexandra opened her mouth wide, tongue flat, and pushed forward. The thick head of my cock slid over her tongue and bumped the back of her throat. She didn’t stop. With a wet, guttural gluck, she forced another inch down, her throat visibly bulging as the shaft disappeared between her glossy red lips. Her green eyes watered instantly, mascara starting to run in dark streaks down her cheeks.
“Fuck…” I groaned, gripping the couch cushion.
She made a wet, choking sound as she held me there, throat convulsing around my thickness. Thick ropes of spit bubbled from the corners of her stretched lips and poured down my shaft in messy streams, dripping onto her tank top and pooling between her breasts. She pulled back just enough to gasp for air, strings of saliva connecting her lips to my glistening cock, then immediately drove down again.
Gluck-gluck-gluck.
The obscene, rhythmic sounds filled the living room. Every time she forced me deeper, her throat swelled visibly with the outline of my cock. She gagged hard, her whole body jerking, but she kept pushing until her nose was pressed against my stomach and her throat was spasming wildly around me.
“Hhrrrk… gluck… hck-hck…” The wet, desperate noises she made were filthy and addictive. Her eyes never left mine, even as tears streamed down her face and spit ran in rivers over her chin. She looked like a complete mess: makeup ruined, lips swollen, throat bulging, and she had never looked hotter, especially as her lipstick was smudged all over my shaft.
She pulled off with a loud, wet pop, coughing and gasping, thick strands of spit dangling from her lips. “God, you’re so thick,” she said, panting. “I can feel you stretching my throat.”
Before I could answer, she dove back down, sucking harder this time. Her head bobbed faster, sloppy and eager. Wet sucking sounds mixed with constant gagging as she tried to take me all the way every time. Her throat muscles rippled and squeezed around my cock, milking me with every desperate swallow.
I was losing control fast.
“Alexandra… I’m gonna cum.”
She moaned loudly around my cock and pushed even deeper. Her throat bulged obscenely one last time as she forced the entire length down, nose pressed against my root and lips kissing the base. That was it. I came hard.
The first powerful spurt shot straight down her throat. Her eyes widened, but she didn’t pull back. She swallowed greedily as I pumped rope after thick rope into her mouth. When she couldn’t swallow fast enough, cum leaked from the corners of her lips, mixing with her spit and dripping down her chin in creamy white streaks.
She stayed down as long as she could, choking and swallowing, until she finally pulled off with a gasping cough. Thick cum and spit poured from her open mouth, dripping onto her tits and soaking her tank top. Her face was a beautiful wreck: red lipstick smeared, mascara running, and chin and cheeks glazed with my load. A long string of cum hung from her bottom lip as she looked up at me, breathing hard, green eyes glassy with lust.
She licked her swollen lips slowly, collecting what she could, and gave me a hoarse, satisfied little giggle.
“Fuck… I think I’m getting better,” she said, voice raw from the abuse. “Your cum tastes way better than the toy.”
She leaned forward and gave the sensitive head one last soft kiss, smearing the mess across her lips like glossy lip gloss.
“Damn, that was intense,” I admitted.
“See?” she said, breathless, wiping her mouth with the back of her hand. “Told you I’d make it feel good.”
I sat there, stunned, cock twitching in the aftermath. She climbed up next to me, nuzzling her head onto my shoulder.
“Can I practise on you later asl well?” she whispered, giggling into my ear. “Your cock’s perfect.”
I didn’t say no.
