C20 Big Tits Stepsister-1

Elena

I never thought my body would betray me like this.

My name is Elena Voss, twenty-four years old, and for the past six months, I’ve been living in hell. A rare neurological condition the specialists couldn’t name, let alone treat. It started as waves of heat rolling through my core at the worst possible moments—during meetings, while driving, even in the middle of grocery shopping. Now it was constant. An unrelenting, throbbing ache between my thighs that made my clit swell and my pussy drip with need until I couldn’t think straight. My nipples stayed hard, rubbing painfully against every fabric. My voluptuous breasts felt heavier, more sensitive, begging to be touched.

I’d tried everything. Toys. Cold showers. Meditation apps. Nothing worked. The arousal only built, sharper and more desperate, until I was reduced to humping my pillow like a bitch in heat every night, fingers buried deep inside my soaked cunt, chasing an orgasm that left me shaking but never satisfied.

Then my stepbrother came back into my life.

Dr. Adrian Kane. The golden boy. Thirty years old, brilliant surgeon, and the last person I ever wanted to see again after our parents’ messy divorce eight years ago. He had always been cold, distant, and unfairly gorgeous—tall, broad-shouldered, with sharp cheekbones, dark hair, and piercing gray eyes that seemed to see right through me. Now he was one of the city’s most respected physicians, running a private clinic known for handling “complex cases.”

Desperation made me call him.

The waiting room of his private clinic was sleek and sterile, all white marble and soft lighting. I sat with my thighs pressed tightly together, trying to ignore the slickness already coating my lace panties. My curves felt obscene in the thin summer dress I’d chosen—my heavy tits straining against the fabric, the hem barely covering my thick thighs.

“Elena.” His deep voice cut through the silence.

I looked up. Adrian stood in the doorway in a crisp white coat over a tailored black shirt, the stethoscope around his neck like a symbol of control. His eyes raked over me slowly, clinically, but there was something darker flickering behind them.

“Follow me.”

He led me to an examination room at the end of the hall. The door clicked shut with a finality that made my pulse spike. The room was equipped for thorough exams: an adjustable table with stirrups, monitors, a camera mounted on a tripod, and glass cabinets filled with medical instruments that looked far too intimate.

“Tell me about your symptoms,” he said, leaning against the counter, arms crossed. His voice was professional, but his gaze lingered on the swell of my breasts.

I stammered through it—the constant arousal, the wetness, the way my body ached for relief that never came. My cheeks burned with humiliation as I described how I’d finger myself raw some nights, how I’d wake up humping the sheets.

Adrian’s jaw tightened. He stepped closer, towering over me. “This condition is rare. Experimental. But I believe I can treat it. Privately. No records. No other doctors. Just you and me.”

My breath hitched. “What kind of treatment?”

He smiled, slow and dangerous. “The kind that requires complete honesty and obedience. Take off your dress and get on the table.”

My hands trembled as I obeyed. The fabric whispered down my body, pooling at my feet. I stood before him in nothing but a black lace bra and matching panties that were already ruined. My big tits spilled over the cups, nipples stiff and visible. My hips and ass curved generously, soft and inviting.

Adrian’s eyes darkened. “All of it.”

I unclasped the bra. My heavy breasts bounced free, full and round with rosy peaks. I hooked my thumbs into my panties and slid them down, revealing my smooth, puffy pussy lips already glistening with arousal. A thick strand of my juices connected to the fabric as I stepped out.

“On the table. Feet in the stirrups.”

The leather was cool against my bare skin. He locked my ankles into the stirrups, spreading my legs wide open. Cool air kissed my exposed cunt. I was completely vulnerable, my slick folds parted, clit throbbing visibly under his gaze.

He pulled on gloves, but the way his fingers traced my inner thighs felt anything but clinical. He adjusted the camera, the red light blinking on. “For research,” he murmured. “I need you to describe every sensation.”

His gloved fingers parted my pussy lips. I gasped as he ran a finger along my slit, collecting my wetness.

“Fuck… Adrian…”

“Doctor Kane during sessions,” he corrected, voice low. But his thumb circled my swollen clit with expert pressure, making my hips jerk.

“Oh god— it’s so sensitive… I’m dripping… please…”

He slid two thick fingers inside me without warning. My walls clenched greedily around them, hot and silky. He pumped slowly, curling to stroke that spongy spot deep inside while his other hand squeezed one of my tits, pinching the nipple hard.

“Tell the camera how it feels,” he ordered.

“It feels… so full,” I moaned, head falling back. “Your fingers are stretching me… I’m so wet I can hear it… I need more… I’m going crazy…”

He added a third finger, fucking me with steady, deep thrusts. The obscene wet sounds filled the room. My breasts jiggled with every plunge. I could feel my orgasm building fast—too fast.

But he stopped right as I teetered on the edge, pulling his fingers out with a slick pop. I whimpered in frustration, pussy clenching around nothing.

“Not yet,” he said. “The treatment requires control.”

He removed the gloves and unzipped his pants. His cock sprang free—thick, long, veined, the head already leaking precum. It was bigger than any toy I’d used, intimidating and beautiful.

“Doctor… please…” I begged, eyes locked on it.

Adrian positioned himself between my spread legs. He rubbed the fat head up and down my slit, coating himself in my juices, teasing my clit until I was shaking.

Then he pushed in.

I cried out as he stretched me open, inch by thick inch. My pussy lips gripped him tightly, fluttering around the invasion. He groaned, eyes half-lidded as he sank deeper, bottoming out against my cervix. The fullness was overwhelming—pleasure bordering on pain.

“Fuck, you’re tight,” he growled. “Sucking me in like you were made for this.”

He started thrusting—slow at first, then harder. The stirrups kept me wide open as he fucked me with clinical precision and raw hunger. Every stroke dragged against my g-spot. My tits bounced wildly. He leaned down, sucking one nipple into his mouth, biting just hard enough to make me scream.

“Yes! Harder—please, Doctor… I’m so close…”

He pounded into me, the table creaking. Skin slapped against skin. My juices squirted around his cock with every brutal thrust. I could feel my orgasm coiling tighter, my walls rippling around his shaft.

“Look at the camera and tell them who’s curing you,” he demanded, slamming deep.

“You are—my stepbrother—fuck, Adrian— I’m coming—!”

My climax crashed over me like a tidal wave. My pussy spasmed violently around his cock, milking him as I screamed, body arching, toes curling in the stirrups. Wave after wave of pleasure ripped through me, soaking his balls and the table beneath us.

But he didn’t stop. He kept fucking me through it, chasing his own release with deep, punishing strokes.

Just as his rhythm faltered and I felt him swell inside me, ready to fill me with his cum, the door to the exam room rattled.

A sharp knock.

“Dr. Kane? Emergency consult in ten minutes. Your father is here—says it’s urgent about your stepsister.”

Adrian froze buried to the hilt inside my still-pulsing cunt. His eyes met mine, dark with lust and something far more dangerous.

My stepfather—his father—was right outside.

And Adrian’s cock twitched deep inside me, still rock hard, as a wicked smile curved his lips.
