I walked into the apartment after my shift and there she was, my older sister Lena, sprawled on the couch in nothing but a thin tank top and panties. We’d lived together for six months since Mom died, both of us over eighteen and trying to make rent. But tonight the air felt different, thick with the smell of her lotion and the low hum of the TV she wasn’t watching.
“Lock the door,” she said without looking up. Her voice was low, the same one she used when she told me what to wear or who not to date. I clicked the deadbolt and dropped my bag. My heart was already beating harder.
Lena stood up and crossed the room. She didn’t ask. She grabbed the back of my neck and kissed me hard, tongue pushing past my lips like she owned the space. I tasted mint and the beer she’d been drinking. My hands went to her waist on instinct, fingers digging into soft skin.
“Been thinking about this all day,” she muttered against my mouth. “You walking around in those tight work pants, ass bouncing. Fucking tease.”
She yanked my shirt up and off, then unhooked my bra with one hand. My tits spilled out and she bent down, sucking one nipple deep while her fingers pinched the other. I gasped and grabbed her hair. She bit just hard enough to make me moan.
“Bedroom,” she ordered. We didn’t make it that far. She shoved me onto the couch, pulled my jeans and panties down in one rough tug, and spread my legs wide. Her fingers slid straight through my wet folds.
“Already dripping for your sister,” she said, voice thick with satisfaction. Two fingers pushed inside me without warning. I arched and cried out as she started pumping, thumb rubbing my clit in tight circles. “Say it. Tell me whose cunt this is.”
“Yours,” I panted. “Fuck, Lena, it’s yours.”
She dropped to her knees and replaced her thumb with her mouth, sucking my clit while her fingers curled inside me. The wet sounds filled the room. I came fast and hard, thighs shaking around her head, but she didn’t stop. She licked me through it and kept going until I was begging.
“Please, I need your pussy too.”
Lena stood, stripped off her tank and panties, and climbed over me in sixty-nine.

Her shaved cunt hovered over my face, glistening. I grabbed her ass and pulled her down, tongue driving straight into her. She tasted salty-sweet and hot. She ground on my mouth while she went back to eating me, both of us moaning like animals.
We fucked like that until our faces were slick. Then she flipped around, straddled my thigh, and started riding it while she fingered me again. Her clit dragged against my skin with every roll of her hips.
“Gonna come all over your leg,” she growled. “Then I’m gonna fuck you with the strap until you can’t walk.”
She did exactly that. After she soaked my thigh she disappeared for thirty seconds and came back wearing the harness, thick dildo bobbing. She bent me over the arm of the couch, spat on my asshole for good measure, and shoved the cock into my cunt in one long thrust. I screamed into the cushion while she pounded me, one hand fisted in my hair, the other slapping my ass.
“Take it, little sister. Take every inch.”
She fucked me until I came again, then pulled out and made me suck the dildo clean before she put me on my back and did it all over again. When she finally came, she pressed the base of the harness against her clit and rode me hard, growling my name.
We collapsed in a sweaty heap on the couch, her fingers still lazily circling my swollen clit.
“Round two in the shower,” she whispered. “Then we’re sleeping naked. I’m not done with this pussy tonight.”
I nodded, already aching for more. The door was locked. The world outside didn’t matter. My sister’s hands were on me and nothing else existed.
