I slammed the bedroom door behind me and stared at my little sister sprawled on her bed in nothing but a too-small tank top and panties. At eighteen, Lisa was all soft curves, thick thighs, and a big round belly that jiggled when she moved. Her heavy tits strained the thin fabric, nipples poking out hard.
"Fuck, you look good enough to eat," I growled, already yanking my shirt off. My cock was throbbing in my jeans.
She grinned, spreading her legs wider so I could see the wet spot on her panties. "Then come eat it, big brother. Been waiting all day for your dick."
I dropped my pants and climbed on the bed, grabbing her soft hips. Her skin was warm and plush under my hands. I hooked my fingers in her panties and ripped them down, exposing her shaved pussy, already glistening. I buried my face between her thick thighs and licked straight up her slit, tasting how sweet and ready she was.
Lisa moaned loud, grabbing my hair. "Yeah, lick that fat pussy. Suck my clit, you dirty fucker."
I did exactly that, sucking her swollen clit while two fingers slid into her tight hole. She was dripping, clenching around me, her chubby belly rising and falling fast. I tongue-fucked her until she came hard, thighs squeezing my head, juices running down my chin.
"Get on your back," she panted, pushing me over. She climbed on top, straddling me. Her heavy tits swung free when she pulled the tank top off. She grabbed my cock and rubbed the head up and down her wet slit before sinking down slow. Inch by inch my dick disappeared into that hot, tight cunt.
"Fuck yes," I grunted, hands sinking into her soft ass cheeks. "Ride that cock, sis. Take every inch."
She bounced on me, her belly and tits jiggling with every drop. The wet slap of her pussy taking my dick filled the room. I reached up and squeezed her big tits, pinching her nipples while she ground down hard, rubbing her clit against me.
"God, your cock feels so good in my pussy," she moaned. "Love fucking my brother. Love how you stretch me open."
I flipped us suddenly, pinning her under me. Her legs wrapped around my waist as I started pounding her deep, hard strokes that made her whole soft body shake. Her pussy gripped me tight, creamy and slick. I fucked her like I owned it, because I did.
"Harder," she begged. "Fuck your chubby little sister harder. Fill me up."
I slammed into her, balls slapping her ass, sweat slicking our skin. Her second orgasm hit fast, pussy pulsing around my cock, her moans turning into screams. I kept going, chasing my own nut, pounding that fat pussy until my balls tightened.
"Gonna cum," I warned.
"Inside me," she gasped.
"Fill your sister's cunt."
I buried myself to the hilt and unloaded, thick ropes of cum pumping deep into her. She milked every drop, clenching and moaning while I emptied my balls.
We lay there panting, my cock still twitching inside her. She kissed me sloppy and deep.
"Round two in the shower?" she whispered, already rolling her thick hips again.
I was hard before she finished the question.
