I came home from my shift at the warehouse and found my nineteen-year-old step-sister Maya sprawled naked on the living-room couch. Her legs were spread wide, one hand lazily circling her clit while the other pinched a dark nipple. She looked straight at me and didnt stop.
Mom and Dad are at that conference till Monday, she said, voice low and filthy. I figured Id stop pretending.
My cock went hard so fast it hurt. Maya had been teasing me for monthsshort shorts, no bra, accidental brushes against my crotchbut this was new. She was completely bare, shaved smooth, pussy already glistening.
I dropped my bag.

Youre really doing this?
She smiled, slow and dirty. Come here and find out.
I crossed the room and knelt between her open thighs. The smell of her arousal hit me hard. I dragged two fingers through her slick folds and pushed them straight into her cunt. She was tight and hot, clenching around me immediately.
Fuck, she breathed. Deeper.
I pumped my fingers hard, thumb grinding her clit. Mayas hips rolled up to meet every thrust. When I curled my fingers against her front wall she gasped and her thighs started shaking.
Dont you dare come yet, I told her. I want that pussy on my cock first.
She laughed, breathless. Then take it out and fuck me.
I stood, yanked my jeans down, and let my thick cock spring free. Maya stared at it, licked her lips, then reached up and wrapped her fingers around the shaft.
Big step-brother dick, she murmured, stroking me. Been waiting to feel this stretch me open.
I grabbed her by the hips, flipped her onto her stomach, and pulled her ass up. Her face pressed into the couch cushions. I lined up and drove straight in, burying every inch in one rough thrust. Maya screamed into the cushion, pussy fluttering around me.
I didnt give her time to adjust. I fucked her hard and fast, the wet slap of skin on skin loud in the quiet house. Her ass jiggled with every slam. I reached under and rubbed her clit in tight circles.
Harder, she begged. Use me like a fucktoy.
I grabbed a handful of her hair and yanked her head back, pounding deeper. Mayas cunt squeezed me rhythmically. She was close already.
Come on my cock, I ordered. Flood it.
She came with a choked cry, pussy pulsing and gushing around my shaft. I kept fucking her through it, chasing my own release. When I felt my balls tighten I pulled out, flipped her onto her back again, and shoved back inside.
Want it inside? I asked.
Fill me up, she panted. I want to feel it leak out of me all weekend.
I came with a grunt, pumping thick ropes deep into her. Maya moaned at every spurt, legs locked around my waist.
We stayed like that for a minute, breathing hard. Then she grinned up at me, still impaled on my half-hard cock.
Round two in the shower, she said. Then were doing it on Mom and Dads bed. I want to be nasty all over their sheets.
I pulled out slowly, watching my cum drip from her swollen pussy, and smiled.
Get your ass upstairs, I told her. Weve got three days and Im not wasting any of them.
