The back of my skull thumped against the headboard with a soft thud. My fingers tangled in Lily's hair, a messy cascade of honey-brown waves that swallowed my vision. All I could see was the part in her hair, the faint scent of her strawberry shampoo, and the impossible, wet heat of her mouth. A low groan vibrated in my chest, escaping as a strained, "Jesus Christ, Lily."
The only answer was a wet, sloppy slrrrrk as she pulled back, her lips dragging along my shaft, a thick strand of saliva bridging her swollen lower lip to my flushed, purple head. Her eyes, huge and blue, flicked up to mine. A smirk played on her glistening mouth. "You taste so good today, Ethan," she murmured, her voice husky and thick. Then she dove back down, taking me so deep the tip nudged the back of her throat. A choked, guttural glrk sound erupted from her, and her whole body shuddered.
This was wrong. This was so fucking wrong. She was my little sister. Nineteen, sure, legally an adult, but my sister. The gap-toothed kid who used to chase fireflies in our backyard. Now she was on her knees between my spread legs, her pink tongue swirling around the swollen crown of my cock like it was her favorite lollipop. And the worst part? I hadn't stopped her. Not the first time she'd "accidentally" walked in on me jerking off three weeks ago and offered to "help." Not the second, or the third. And definitely not now, on a lazy Saturday afternoon when our parents were at a weekend gardening convention two states over.
My hips gave an involuntary little buck, pushing myself deeper into that wet, tight suction. Lily's moan was a muffled, happy vibration that traveled straight up my spine. Her hands, small and soft, kneaded the tense muscles of my thighs before sliding up to cradle my balls, rolling them gently in her palm. The sensation was electric, a jolt of pure pleasure that made my toes curl against the rumpled sheets.
"Fuck, fuck, fuck," I chanted, a broken mantra. My grip on her hair tightened, not to push her away, but to guide her, to feel the rhythm of her bobbing head. "You're gonna make me… Lily, you have to stop…"
She ignored me. She always ignored me when I said that. Her technique was obscenely good, a mix of practiced suction, agile tongue flicks against my frenulum, and a willingness to deep-throat that left me lightheaded. She pulled off with a wet pop, a string of spit and pre-cum connecting her lips to my weeping slit. She panted, her cheeks flushed.
"You don't want me to stop," she whispered, her breath hot against my wet skin. She leaned forward and lapped at the bead of moisture gathering at the tip, a slow, deliberate swipe of her tongue. "I can feel how much you don't want me to stop. Your dick is throbbing in my mouth." She said it so matter-of-factly, like she was commenting on the weather.
"It's wrong," I managed to gasp, even as my hips lifted off the bed, seeking her mouth again.
"It doesn't feel wrong," she sing-songed, and then swallowed me down to the root in one smooth, practiced motion.
My vision whited out for a second. The sensation was overwhelming—the tight constriction of her throat, the wet, silken friction of her mouth, the obscene, sucking noises that filled the quiet room. Schlup. Glllp. Slrrk. She set a brutal, relentless pace, her head bobbing fast and deep, her nose burying itself in my trimmed pubic hair with every downward plunge. Drool dripped from the corners of her mouth, slicking my balls and soaking the base of my cock.
I was losing it. The coil in my gut wound tighter and tighter, a spring of pure pressure. My balls drew up, tight and heavy. "Lily, I'm gonna… you need to…!"
She just hummed in affirmation, the vibration making me see stars. Her hand left my balls and snaked between her own legs, hidden under her little cotton sleep shorts. I could see the frantic motion of her arm, hear the wet, sticky sounds her fingers made as she rubbed herself. Her moans grew louder, less muffled, blending with the slick cacophony of her mouth on my cock.
That did it. The sight of her getting off on sucking me off shattered the last shred of my resistance. A raw, animal sound tore from my throat. "Oh, God! Lily!"
The orgasm hit me like a freight train. My back arched off the mattress, every muscle in my body locking tight. The first pulse was a deep, internal convulsion, and then a hot, thick rope of cum shot straight down her throat. I felt her swallow instinctively, a strong, convulsive gulp. But there was too much. I'd been backed up for days, thinking of her, and now it was a flood.
Splurt. Splurt. Gush.
The second and third bursts were too powerful, overflowing her mouth. Milky white cum spilled out over her stretched lips, coating her chin. She pulled back, gasping, but kept her mouth open around the head, milking me with gentle sucks as I continued to erupt. Splort. Splat. Thick, pearlescent strands painted her face—across her cheek, over the bridge of her nose, a fat glob landing on her eyelash. More jetted onto her chest, soaking through the thin fabric of her tank top, darkening the pink cotton and outlining the hard points of her nipples beneath.
I collapsed, boneless and panting, into the damp sheets. My cock, slick and spent, twitched in the cool air. Lily stayed on her knees, breathing heavily, her face a glistening, sticky mess. She slowly ran her tongue over her lips, gathering the cum there, and swallowed with a deliberate, satisfied ahhh. She opened her eyes, those big blue pools looking at me with a mix of triumph and pure, unadulterated lust.
"See?" she breathed, her voice hoarse. "You came so much. You filled my whole mouth." She wiped a finger through the mess on her cheek and brought it to her lips, sucking it clean with a soft, sucking noise. "It's so warm. And thick. I love it."
I couldn't speak. I could only stare, my heart hammering against my ribs, a cocktail of shame, disgust, and the most intense, soul-deep satisfaction I'd ever felt swirling in my gut.
She crawled up the bed, moving with a feline grace that felt newly predatory. She straddled my hips, her soaked tank top pressing against my stomach. The smell of sex and strawberries was overwhelming. She leaned down, her cum-smeared face inches from mine. Her breath hit my lips.
"You're mine now, Ethan," she whispered, her tone shifting from playful to something more possessive, more intense. "My big brother. My big, hard brother. And I'm never gonna stop. You know that, right?"
She didn't wait for an answer. She crushed her mouth to mine. The taste was shocking, salty and musky and uniquely me, mixed with the sweetness of her. I recoiled instinctively, but her hand slid behind my head, holding me in place. Her tongue pushed past my lips, forcing me to taste my own release from her mouth. It was the most depraved, corrupting kiss imaginable. And despite everything, a weak, traitorous moan escaped me. My hands, which had fallen limp at my sides, rose to grip her waist through her shorts.
She broke the kiss, panting. A wild, goofy grin spread across her sticky face. "You liked that." It wasn't a question.
"Lily, this is…"
"Shhh," she said, placing a sticky finger on my lips. "Don't think. Just feel." She shifted her weight, grinding her clothed pussy down against my softening cock. Even through the fabric, I could feel the intense heat and the soaked wetness. A dark patch had spread across the cotton of her shorts. "See? I'm so wet for you. I came when you came in my mouth. I squirted all over my shorts. Wanna feel?"
Before I could protest, she hooked her thumbs into the waistband of her shorts and panties and pushed them down in one rough motion. She kicked them off the bed. Then, holding my gaze, she lifted her tank top over her head and tossed it aside. She was completely naked, kneeling over me.
I'd never seen her like this. Not fully. My brain short-circuited. Her body was… perfect. Slender, but with soft, tempting curves. Her breasts were small and pert, with pink, peaked nipples that looked hard and sensitive. A dusting of faint freckles crossed her chest. My eyes dragged downward, over the flat plane of her stomach, to the thatch of honey-brown curls at the junction of her thighs. And between them… her pussy was glistening, swollen, and utterly exposed. The outer lips were plump and flushed a deep pink, parted slightly to reveal the slick, darker inner folds, which glistened with a mixture of her arousal and what looked like the clear evidence of her squirting. The scent of her, musky and sweet and primal, filled the air.
"Look at me," she commanded, her voice losing its playful edge, taking on a new, dominant tone. "Look at what you do to me."
I was looking. I couldn't look away. My cock, impossibly, gave a feeble twitch against my stomach.
She saw it. Her grin widened. "You're not done, are you? I'm not done." She reached behind her, her hand finding my half-hard length. Her grip was firm, knowing. She stroked me slowly, smearing the remnants of my cum and her spit along my shaft. "I want you inside me, Ethan. I want to feel you fuck me. I want you to fill my pussy like you filled my mouth."
"No," I croaked, the word having no force whatsoever. "We can't. That's…"
"That's what?" she challenged, leaning forward so her breasts brushed my chest. Her nipples were hard little pebbles against my skin. "It's already happened. You're already my dirty little secret. My big brother who lets his little sis suck him dry every chance she gets." She positioned the head of my cock at her entrance. The heat radiating from her was incredible. I could feel her wetness against me. "Just the tip," she whispered, a parody of seduction. "Just to see how it feels."
She sank down.
It wasn't just the tip.
The resistance was immediate, a tight, clinging ring of muscle that yielded with a soft, wet push as she impaled herself on me. Her head fell back, a choked scream tearing from her throat. "Fuuuuck!"
She was impossibly tight. Hotter and wetter than her mouth, a silken, clutching vise that squeezed me from all sides. She bottomed out, her ass coming to rest on my thighs, my entire length buried inside her. She froze, her body trembling violently, her inner walls fluttering and clenching around me in erratic pulses.
"Oh my God," she sobbed, tears springing to her eyes. "Ohmygodohmygod… you're so big. You're splitting me open." Her words were fragmented, breathless. She wasn't faking it. Her face was a mask of overwhelmed, agonized pleasure.
The feeling was indescribable. The forbidden intimacy of it, the crushing tightness, the knowledge that this was my sister's body accepting me… it was like mainlining sin. A guttural groan ripped from my chest. My hands flew to her hips, my fingers digging into the soft flesh. I was fully hard again, painfully so, stretched to my limit inside her.
"Move," I gasped. "Lily, please, move."
She began to rock, a slow, tentative grind that sent shockwaves through us both. Her wetness made a slick, squelching sound with each tiny movement. Squish. Schlup.
"Nnngh… right there… Ethan…" she moaned, her eyes rolling back. She found a rhythm, lifting herself up until just the head remained inside, then sliding back down in a slow, torturous descent. Each time she sheathed me completely, a sharp, punched-out gasp escaped her.
I couldn't take the slow pace. The corruption was complete. The dam had broken. I grabbed her hips tighter and thrust upward, meeting her downward stroke.
"Yes!" she shrieked.
I set a punishing pace, driving into her from below. The bedsprings screamed in protest, a metallic screech-screech-screech harmonizing with the wet slaps of our bodies meeting. Smack. Smack. Splat. Her breasts bounced wildly, her entire body jolting with each deep drive. Her mouth hung open, drool mixing with the drying cum on her chin.
"You like that?" I growled, the dominant role feeling foreign but intoxicating. "You like your brother's cock in your little cunt?"
"Yes! Daddy, yes!" she screamed, the wrong name slipping out in her ecstasy, making the whole thing ten times more depraved.
Her inner muscles clenched around me like a fist. Her body went rigid. A high, keening wail tore from her throat, and then a gush of warm liquid soaked my pelvis and the sheets beneath us with a sound like a faucet turning on. Ssssshhhhlurp.She squirted, hard, the clear fluid spraying out around where we were joined, drenching us both. Her orgasm triggered my own. With a final, brutal thrust, I buried myself to the hilt and let go.
This orgasm was different. Deeper, more visceral. It felt like my soul was being pulled out through my cock. Splurt. Gush. Rope after rope after rope of thick, hot cum flooded her depths, pumping into her with relentless force. I could feel it filling her, could feel her swollen walls trying to contain the massive load. Some of it began to leak out almost immediately, a thick, white trickle that seeped past our joining and dripped onto my balls.
We collapsed together in a heap of slick limbs and shuddering breaths. I was still inside her, softening, but still intimately connected. The room stank of sex, sweat, and strawberries. The evidence of what we'd done was everywhere—on her face, on her chest, between her legs, all over the sheets.
Several long minutes passed in silence, broken only by our ragged breathing. Then Lily stirred. She lifted her head from my chest. Her face was a wreck—mascara smudged, tears and cum and drool dried in streaks. But she was smiling. A sleepy, sated, utterly corrupt smile.
She shifted, and I slipped out of her with a soft, wet plop. A gush of my cum followed, spilling out of her and pooling on my thigh, warm and thick. She didn't seem to mind. She traced a finger through the mess on my stomach, then lifted it, examining the milky white strings.
"Told you I couldn't stop," she murmured, her voice raw. She sucked her finger clean. "And now you can't either."
She nestled her head back on my chest, her hand resting possessively on my hip. I stared at the ceiling, the reality of the situation crashing down on me. I'd just had the most intense, unbelievable sex of my life. With my sister. And she was right. I didn't want her to stop. The shame was there, a cold knot in my stomach, but it was drowned out by the memory of her tight heat, her screams, the feel of my cum inside her. I was well and truly fucked. In every sense of the word.
