She showed up at my door on a hot July night, twenty-two years old, tight tank top clinging to her full tits and cutoffs riding up her thick ass. My brother's daughter. My niece. And from the second she stepped inside, I knew exactly what she wanted.
"Uncle Mike," she said, voice low and sweet, "I can't stay at Dad's anymore. Too many rules. Can I crash here a while?"
I let her in. Within an hour she was on my couch, legs spread just enough to show the edge of her white panties. She caught me looking and didn't close them. Instead she smiled, slow and filthy.
"You always stare at me like that?" she asked.
I didn't lie. "Yeah. Since you turned eighteen."
She stood, peeled the tank top off, and let those heavy tits bounce free.
Pink nipples already stiff. "Then stop staring and come fuck your niece."
I had her bent over the arm of the couch in under a minute. Shorts and panties yanked down, ass up, pretty pink pussy already glistening. I slapped my cock against her wet slit a few times, then shoved in deep. She was tight, hot, and soaked. She moaned loud, pushing back to take every inch.
"Fuck, Uncle Mike, your cock feels so much bigger than I imagined," she gasped.
I gripped her hips and pounded her, balls slapping against her clit with every thrust. The wet sounds filled the room. She reached back, spread her ass cheeks wider so I could watch my thick shaft stretch her hole. Every time I bottomed out she whimpered and clenched around me.
I pulled out, flipped her onto her back, and shoved her knees to her chest. Her pussy was red and puffy, dripping. I slammed back in and fucked her hard, watching her tits bounce. She played with her clit while I drilled her, eyes locked on mine.
"Fill your niece up," she begged. "Cum deep in this pussy."
I did. I buried myself to the hilt and unloaded, thick ropes of cum pumping straight into her. She came with me, cunt milking every drop, thighs shaking.
We didn't stop there. She spent the next week walking around my place naked or in tiny shorts, bending over on purpose. I ate her pussy on the kitchen table while she moaned my name. She sucked my cock in the shower, gagging on it, drool and spit running down her chin, then swallowed every spurt. One afternoon I took her ass while she fingered her cum-filled pussy, stretching her tight hole around my dick until she screamed.
By the end of the week she was riding me reverse cowgirl on the living room floor, ass cheeks spread, my cum leaking out of her pussy and down my balls while she begged for more.
"Best erotic sex stories niece ever," she laughed breathlessly after another load.
I smacked her ass and told her to keep riding. She did.
