Step Sister's Gravity-Defying Tits: Almost Lost It!

The scent of her vanilla musk hung heavy in the humid bedroom air, thick enough to taste—sweet and raw. Her massive, natural tits, heavy globes straining against the thin lace of her bra, bounced with every shallow breath. My knuckles were white where I gripped the edge of the mattress, watching the wet shine pool between her thighs. She leaned over me, a predatory smirk twisting her lips, her dark hair spilling like silk down her chest. "You look like you're about to explode, little brother," she purred, her voice a gravelly invitation. I lunged, hands burying themselves deep into the soft flesh of one breast, pulling it taut until the nipple hardened into a perfect, aching peak. "Fuck me harder!" I gasped, tilting my head back as her tongue flicked out to trace a path down my jaw. The salty taste of her spit was electric. She pushed her hips down, grinding that unbelievable ass against my straining cock, the friction sending jolts straight to my groin. "Take my cock deep," she commanded, her breath hot against my earlobe. I drove up, burying myself past the slick folds of her pussy, feeling the internal clench wrap around me. "Cum inside me!" I roared, finally losing control as she arched back, milking every last drop from my desperate thrusts.
