She walked into the kitchen wearing nothing but my old t-shirt, the hem barely covering her ass. I knew right then I was going to fuck my sister again.
"Matt, you left the coffee on too long," she said, pouring a cup like it was any normal morning. But the way her nipples poked through the thin fabric told me she was already wet.
I stood up from the table, my cock already hard in my shorts. "Come here, Lisa."
She set the cup down and came straight to me, dropping to her knees without a word. Her hands yanked my shorts down and she took my dick in her mouth like she had been thinking about it all night. Wet, sloppy sucks, her tongue swirling around the head while she looked up at me with those big eyes. "Fuck, your cock tastes good this morning," she mumbled around it, spit dripping down her chin.
I grabbed her hair and pushed deeper, making her gag. "That's it, take it all. You're such a dirty little sister." She moaned and swallowed more, her hand reaching up to stroke my balls. I could feel her throat working, tight and hot.
After a minute I pulled her up and bent her over the kitchen table. The t-shirt rode up, exposing her bare ass and the glistening pussy between her legs. No panties, of course. I slapped her ass hard, leaving a red handprint. "You came down here wanting this, didn't you?"
"Yes," she breathed. "I woke up thinking about you pounding me again."
I lined up and slammed into her in one thrust. She was soaked, tight walls gripping me as I started fucking her hard. The table creaked with every thrust. Her tits pressed flat against the wood while I drove in deep, balls slapping against her clit. "Goddamn, your pussy is perfect," I growled. "So much better than any other cunt I've had."
Lisa pushed back against me, meeting every stroke. "Harder, Matt. Fuck your sister like you mean it." I reached around and rubbed her swollen clit, feeling her juices coat my fingers. She came fast, crying out and clamping down on my cock, her whole body shaking.
I didn't stop. I flipped her onto her back on the table, spread her legs wide, and kept pounding. Her tits bounced with each thrust, nipples hard. I leaned down and sucked one into my mouth, biting just enough to make her gasp. "Tell me how much you love your brother's dick," I demanded.
"I fucking love it," she panted. "Love how you stretch me open. Love feeling your cum inside me."
That pushed me over. I buried myself to the hilt and unloaded, thick ropes of cum flooding her pussy. She milked every drop, legs wrapped around my waist to keep me deep. When I finally pulled out, my load leaked out of her and ran down her ass onto the table.
She sat up, scooped some with her fingers, and licked them clean. "Mmm. Tastes even better mixed with my juice."
We didn't talk much after that. She went to shower and I headed to work, but all day I kept thinking about what we'd do when I got home. That night she came to my room wearing just a towel. It dropped to the floor the second the door closed.
"Want to fuck my ass tonight?" she asked, climbing onto the bed on all fours.
I grabbed the lube from the drawer and slicked my cock. Her asshole was already relaxed from the plug she'd been wearing earlier. I worked two fingers in first, then pressed the head of my dick against her. She pushed back and I slid inside, slow at first then harder once she opened up. "Fuck yes, fill my ass," she moaned into the pillow.
I gripped her hips and railed her, watching my cock disappear between her cheeks. Every thrust made her moan louder. I reached under and fingered her pussy, feeling my own cum still inside from earlier. She came again, ass clenching around me, and I followed right after, pumping another load deep in her guts.
We collapsed together, sweaty and breathing hard. She turned and kissed me, tongue pushing into my mouth. "We can't stop doing this," she whispered. "I don't care if it's wrong. Your cock belongs in me."
The next weekend our parents were out of town again. We had the whole house. Lisa spent the day walking around naked, bending over every chance she got so I could see her holes. By dinner I had her on the couch, legs over my shoulders, pounding her pussy while she rubbed her clit. "Cum in me," she begged. "I want to feel it leak out all night."
I did, then made her sit on my face so I could eat her out while my cum dripped into my mouth. She ground against my tongue until she squirted, soaking my chest.
Later we showered together. She soaped up my cock and jerked me off against her stomach, then turned around so I could fuck her standing up, water running down our bodies. Her back arched as I thrust up into her, one hand pinching her nipple, the other holding her throat just tight enough. "You're mine," I told her. "This pussy is mine."
"Yours," she agreed, voice hoarse. "Only yours."
We went to bed after that but woke up twice more during the night. Once for slow, deep missionary where I stayed inside her after cumming, just holding her. The second time she woke me by sucking my cock back to hardness and riding me until we both came again, her tits bouncing in my face.
By Sunday we were sore and satisfied, but already planning the next time. She kissed me at the door before our parents got home. "Same time next week?" she asked, hand squeezing my cock through my jeans.
"Count on it," I said.
And we did. Every chance we got, raw and dirty, no holding back. Just two adults who knew exactly what they wanted from each other.
