My step-sister jerks my cock on her big tits in leather lingerie and gets cum copiously on it

It was a sultry summer afternoon, and I found myself lounging on the living room sofa, my mind wandering to unspeakable places. The sun streamed through the open windows, casting a warm glow across the room. That’s when I heard the click of the front door opening, followed by the clacking of high heels against the hardwood floors. I knew immediately it was her – my step-sister, the object of my forbidden desires.

She emerged from the foyer, a vision in black leather. A tight corset cinched her tiny waist, accentuating her full, heaving breasts that threatened to spill out at any moment. The skimpy thong hugged the curves of her round ass, leaving little to the imagination. Her fishnet stockings and towering platform boots completed the sinful ensemble.

“How’s my big step-brother doing today?” she purred, sauntering over to where I sat. Her full, glossy lips formed a seductive smile as she ran a hand through her long, wavy hair. “I just had the wildest fantasy, and I need you to help make it come true.”

My heart raced as she knelt before me, her ample cleavage inches from my face. She reached out, trailing a perfectly manicured nail down the front of my shorts. I could feel my cock begin to harden, straining against the confines of my pants.

“Please baby, I want to suck your big hard cock,” she whispered, her hot breath caressing my ear. “I want to feel it throb between my tits, coating them in your hot, sticky cum. Will you fuck my tits for me?”

I groaned, unable to resist her wanton charms any longer. With shaking hands, I reached out, cupping her bursting cleavage in my palms. Her breasts were soft and supple, filling my hands perfectly. She moaned as I squeezed them, pushing her chest closer to my touch.

She deftly unbuckled my belt and unzipped my fly, freeing my rigid cock from its cotton prison. It sprang forth, hard and thick, the head already glistening with moisture. She licked her lips hungrily, eyeing my manhood like a starving woman.

“Fuck, baby, your cock is so big and thick. I can’t wait to feel it between my tits,” she said, her voice thick with lust. She leaned forward, running her tongue along the underside of my shaft, from base to tip. I shuddered, holding on to her breasts for dear life.

Slowly, she wrapped her tits around my throbbing cock, the soft flesh enveloping me like silk. She squeezed them together, forming a tight, warm channel. I gasped as she began to move, sliding her breasts up and down my length in a delicious, torturous rhythm.

“Oh fuck, your tits feel so good,” I grunted, my hips bucking involuntarily. She giggled, picking up the pace. Her drool dribbled down between her breasts, making them glisten in the sunlight. The sight of my cock gliding through her cleavage, slick with her saliva, was almost too much to bear.

“Mmmm, I love having your big cock between my tits,” she moaned, her eyes locked on mine. “I want to feel you explode all over them. Paint my tits with your hot cum, baby.”

Her filthy words pushed me closer to the edge. My balls tightened, the urge to erupt growing with each pump of my hips. She sensed I was close, squeezing her breasts around me even tighter. The friction was incredible, her pillowy mounds massaging every inch of my sensitive skin.

“I’m gonna cum!” I warned, my voice strained. “Fuck, I’m gonna cum all over your beautiful tits!”

With a guttural cry, I let go, my cock pulsing as I released a torrent of hot, sticky seed. Jets of thick cum spurted from the tip, splattering across her heaving cleavage. She moaned in delight, watching my cock throb against her flesh. I painting her breasts with my essence, covering them inch by glorious inch.

“Oh baby, yes! Fill my tits with your cum!” she encouraged, pumping her breasts faster. My balls clenched again, and I had another powerful orgasm. This time, the cum landed on her throat, stringing together to form a bridge between her breasts.

Finally, my climax subsided, leaving me gasping for breath. My cock twitched against her chest, the last few drops of cum oozing out. She released her grip on her breasts, giving them a gentle squeeze. My seed oozed from between them, sliding down her body in lewd streaks. She scooped some up with a finger, bringing it to her mouth and licking it clean.

“That was so hot, baby,” she purred, leering at me with lust-filled eyes. “Your cum feels so good on my skin. I can’t wait to do it again.”
