Caught my stepsister masturbating in the closet, i fucked this busty beauty

I couldn’t believe my eyes as I crept up to the half-open closet door, my heart pounding in my chest. There, illuminated by a single bare lightbulb, was my tantalizingly beautiful stepsister Rebecca, immersed in the throes of self-pleasure. Her ample breasts heaved with each ragged breath, the ivory flesh glistening with a sheen of sweat. One hand was buried between her milky thighs, while the other kneaded and plucked at her stiffening rosy nipples.

My cock surged to attention, straining against the confines of my jeans as I watched this delicious forbidden act unfold before me. Rebecca’s eyes were screwed shut in concentration, her plush fuck-me-please lips parted as she hummed and writhed on the closet floor. My mind raced with sinful fantasies – grabbing those gorgeous tits, spreading that juicy ass, ramming my hard dick into her needy cunt until she screamed…

Just then, Rebecca’s eyelids fluttered open and she locked gazes with me, shock and shame flashing across those innocent baby blues. Before she could recover enough to scream, I lunged forward and captured her mouth in a searing, punishing kiss. For a moment, she squirmed in protest, but I was bigger and stronger. I held her still and pressed my tongue past her plump lips to taste the sweet wetness within.

To my delight, Rebecca’s struggles gave way to moans as she began returning my kisses with equal fervor. Her free hand came up to tangle in my hair and pull me closer as she opened her mouth wider, letting me plunder her hot sugary cavern. Our tongues swirled together lewdly and I could taste the remnants of her arousal.

I tore my mouth from hers and crashed my body down onto Rebecca’s, pinning her back into the closet wall. My hands roamed her generous curves, mapping every inch I’d been foolishly denied since my stepmother had brought this little temptress into our lives. Rebecca gasped and arched into my touch like a cat in heat, and I couldn’t resist giving her heaving tits a rough grope. More of that delicious fuck me juices gushed from her sopping slit as I thumbed her nipples through the thin fabric of her shirt.

“God, Rebecca, I’ve wanted to fucking do this for so long,” I growled into the shell of her ear as I nipped and licked the tender skin of her neck. “You have no idea how many times I’ve lain awake at night, stroking my hard cock thinking about those tits, that tight little pussy…”

Rebecca whimpered and let her head fall back against the wall, exposing more of her ivory throat to me. “Please,” she gasped, “I’ve wanted you too. Fucking take me, please your little sister…”

Emboldened, I gave her taut pink nipples a brutal tweak through her shirt before yanking the garment over her head. Her massive tits bounced free and I lunged forward to capture one furled bud between my lips, suckling greedily as my other hand continued its assault on the other pearled tit. Rebecca thrashed and writhed beneath me, her nails raking down my back as her cries of pleasure rose to an fever pitch.

I released her breast with a pop and quickly divested her of the tiny scrap of fabric masquerading as panties and sheathed my throbbing member in its silken folds. Rebecca’s cunt quivered and clenched around me, drawing me deeper into her hot wetness. I pulled back until just the tip remained inside her and then surged forward again, burying myself to the hilt in one powerful thrust. Rebecca screamed, digging her nails into my shoulders hard enough to draw blood as I began to pound into her mercilessly.

My thrusts grew harder and more erratic as my impending orgasm approached. Rebecca wrapped her long legs around my waist, urging me deeper with each roll of her hips. Her moans and whimpers spurred me on and I redoubled my efforts, my balls slapping against her ass with each frenzied shove of my hips.

“Fuck, Rebecca, I’m gonna come!” I bellowed as my climax fizzed through my veins like a sprinkler let loose in a fucking torrential downpour. My cock twitched once before erupting with a full-blown spray of hot seed, painting Rebecca’s babymaker with my essence and sealing our forbidden coupling. Rebecca followed a moment later, her voice rising in a loud keening cry that was probably heard all throughout the house as she toppled over into sweet release, her velvety walls milking my cock for every last drop of come.

As our passionate coupling ended, I reluctantly pulled out of Rebecca’s welcoming warmth, wincing slightly at the transfer of our fluids between us. Rebecca shakily sat up, revealing her complete nudity to my appreciative gaze. Her skin was flushed and glowing, her ample bosom heaving with exertion, and her legs still spread in lewd invitation.

“So…” she began with a coy flutter of her lashes, “any chance you might want to fuck your naughty little sister again sometime?” Her hand slid down to brush over her swollen clit and she gave me a filthy smile, “I’m going to need a lot more of this attention now that you’ve gotten a taste of my tight cunny…”

I groaned and unzipped my jeans, letting out my rock hard cock, “Oh trust me Rebecca, I intend to fuck you very, very thoroughly – all night long.”

Rebecca giggled sultrily and wiggled her ass at me, “Lead the way big boy.”
