The morning after denial night hit me like a fever dream I couldn’t wake from. My chest still carried the faint sticky sheen of her release from when she’d squirted across my skin, and the silk scarf lay coiled on the nightstand like a reminder of how completely she’d owned me. I’d barely slept, cock throbbing through the dark hours while her whispered promise echoed in my skull: “Tomorrow ... your real lesson begins.” Guilt clawed at me harder than ever—this was my step-aunt, the woman who’d moved in to keep the house running, and I’d let her gag me, ride my face, and leave me begging like a desperate animal. But the ache between my legs had turned into something feral, something that needed her heat around me more than air.
I stumbled downstairs in nothing but loose boxers, heart already racing. The living room smelled of fresh coffee and her vanilla-cherry lotion, sunlight pouring across the hardwood floor in wide golden bands. Tara stood in the center of the room wearing one of the new sheer black babydolls from yesterday’s shopping trip, the lace so delicate it might as well have been painted on. The hem barely skimmed the tops of her thighs, and when she turned toward me the fabric shifted, revealing the soft, bare swell of her pussy and the way her full, rounded breasts strained the cups, nipples already tight and dark against the sheer material.
She smiled that sweet, wicked auntie smile and crooked a finger. “Come here, Ryan. The floor’s nice and soft. I want you right here for your first real lesson.”
My knees went weak as she sank down onto the thick rug, pulling me with her until we knelt face to face. She cupped my jaw, thumb brushing my lower lip, eyes locked on mine with that calm, total control that made my cock twitch hard against the thin fabric of my boxers.
“No more teasing today, baby,” she whispered, voice low and honey-thick. “Today I’m going to fuck you. Slow at first. Deep. I want you to feel every inch of what you’ve been aching for.”
She pushed my shoulders until I lay flat on my back, the rug warm against my skin. Then she straddled me, knees planted wide, the babydoll riding up to expose her glistening folds hovering just above my straining length. She reached down, hooked her fingers in my waistband, and tugged my boxers off in one smooth motion. My cock sprang free, angry-red and leaking, veins pulsing visibly. She wrapped her hand around it once, giving a single slow stroke that made me groan, then positioned the thick head right at her entrance.
“Look at me,” she ordered softly. Her eyes held mine as she sank down—slow, deliberate, inch by torturous inch. The wet heat of her pussy enveloped me like liquid silk, tight and slick and impossibly perfect. I felt every ridge, every flutter as her walls stretched around me, taking me deeper until her ass settled flush against my thighs and I was buried to the hilt inside my step-aunt.
“Fuck ... you’re so deep,” she breathed, not breaking eye contact for a second. Her hands braced on my chest, full breasts swaying heavily inside the sheer lace as she started to move—long, rolling strokes that dragged her clit along my shaft on every downstroke. The babydoll slipped off one shoulder, letting one lush breast spill free, the soft weight bouncing with each rise and fall. I watched it mesmerized, the dark nipple tracing lazy circles in the air.
She leaned forward, letting that heavy tit brush my lips. “Suck it while I ride you, baby. Feel how full I am with you inside me.”
I latched on, tongue swirling around the stiff peak while she picked up the pace. Her hips rolled in perfect rhythm, pussy clenching around me in wet, rhythmic pulses that made obscene, slick sounds fill the sunlit room. Every time she bottomed out her breasts slapped softly against my face, the plush give of them smothering me for a heartbeat before she lifted again. I could feel the weight of them dragging across my skin, nipples grazing my cheeks, the faint salt of her sweat mixing with the sweet cherry scent that clung to her.
“That’s it ... worship those tits while I fuck you,” she moaned, voice growing breathier. “Tomorrow I’m going to make you come just like this—deep inside your aunt’s pussy. I want you to fill me up, Ryan. Pump me so full it leaks out for days. Breed me like the good boy you are.”
