The final night pressed in like a storm that had been building for twelve days, thick and electric, every second humming with the knowledge that my parents’ plane would touch down tomorrow. The house was quiet except for the low hum of the refrigerator and the distant chirp of crickets outside the open living-room windows. Tara had kept the lights low, only the soft glow from the floor lamp casting long shadows across the couch where I sat, heart already hammering. She stood in front of me in the full lingerie set from our shopping trip—black lace corset laced so tight her waist looked impossibly small, the cups overflowing with the soft, rounded weight of her breasts, garter straps taut against her thighs, sheer black stockings, and those red-bottom heels that clicked with every slow step she took toward me.
She didn’t speak at first. Just let me look. The corset pushed everything up and out, her nipples already stiff and dark against the delicate fabric. A tiny thong was the only thing between her legs, and even that was already damp. She reached behind her back, unhooked the corset with a practiced flick, and let it fall away. Her breasts spilled free, full and heavy, swaying with the motion as she climbed onto my lap facing me.
“Tonight we don’t stop,” she whispered, voice low and rough with need. “Every position. Every inch of you inside me until we can’t move. And when you come, I want it all. Every single drop is mine.”
She slid down my body until her breasts enveloped my cock. The warm, plush valley surrounded me completely, soft skin sliding against my shaft as she pressed them together with both hands. I groaned at the sight—my length disappearing between those lush mounds, the head peeking out at the top with each slow stroke she gave. She leaned down, tongue flicking out to taste the bead of pre-cum at the tip, then started moving, sliding her tits up and down in long, deliberate glides. The friction was perfect, warm and silky, her nipples brushing my stomach on every upstroke. I thrust between them, watching the way they bounced and molded around me, the faint sheen of sweat already starting to glow on her skin under the lamplight.
She kept the rhythm steady, eyes locked on mine, until I felt that familiar tightening. “Give it to me,” she murmured, squeezing tighter. I came hard, thick ropes painting the tops of her breasts and dripping down the soft curves. Without missing a beat she scooped it up with two fingers, brought them to her mouth, and licked them clean while staring straight at me. Then she lowered her head and sucked the last drops straight from my cock, tongue swirling until I was twitching and oversensitive.
She climbed higher, turning around so her pussy hovered above my face. I grabbed her hips and pulled her down, burying my tongue inside her as she took me back into her mouth. The 69 was immediate and filthy—her thighs clamped around my head, her slick folds grinding against my lips while she bobbed on my shaft. Her breasts draped heavy over my stomach, the soft undersides dragging with every movement of her head. I licked deep, tasting her, sucking her clit until her moans vibrated around me and she came with a shudder, flooding my tongue. She swallowed every drop of my second load a moment later, humming with satisfaction as she licked me spotless.
We didn’t stop to breathe. She spun off me, dropped to her hands and knees on the thick rug, and looked back over her shoulder. “Doggy. Hard.”
I knelt behind her, gripped those full hips, and sank into her soaked heat in one thrust. The angle was brutal and perfect. Her ass rippled with every snap of my hips, the garter straps snapping against her skin. I reached forward and wrapped her long dark hair around my fist, tugging just enough to arch her back further. My other hand slid around to her throat, gentle pressure that made her clench around me like a vice. “Fill me,” she gasped, pushing back to meet every thrust. “Breed your aunt’s pussy until it’s overflowing.” I drove deeper, the wet slap of our bodies loud in the quiet house, her breasts swinging heavily beneath her. She came hard, walls fluttering, and I followed, pumping another load deep inside her. She reached between her legs, scooped what leaked out, and licked it from her fingers with a wicked smile.
