We were home alone for the weekend while our parents were out of town. I was twenty-two and she was twenty-one, both of us back from college and bored as hell in the big empty house. She walked into the living room wearing nothing but one of my old t-shirts that barely covered her ass. Her tits pushed against the thin fabric and her nipples were hard. I could see the outline of them clear as day.
"Stop staring, perv," she said, but she smiled when she said it. She sat next to me on the couch and spread her legs just enough that I caught a glimpse of her shaved pussy. No panties. She knew exactly what she was doing.
I didn't waste time. I grabbed her thigh and pulled her closer. "You want me to fuck you or what?" I asked straight out.
She looked me in the eye. "Yeah. I've been thinking about your cock all week. Fuck me."
I yanked the shirt over her head. Her tits bounced free and I sucked one nipple hard while my hand went between her legs. She was already wet. Two fingers slid right into her tight cunt and she moaned, grinding down on my hand.
"Get my dick out," I told her. She unzipped me fast and pulled my cock free. It was rock hard and leaking. She wrapped her hand around it and started stroking, thumb rubbing over the head.
"Suck it," I said. She dropped to her knees between my legs and took me into her mouth. No teasing. She went straight to deep-throating, gagging on it but not stopping. Spit ran down my shaft as she bobbed her head. I grabbed her hair and fucked her face a little, pushing deeper until her nose hit my stomach.
When I pulled her off she was gasping, strings of spit connecting her lips to my cock. "Fuck me now," she begged. "I want you to cum inside me."
I flipped her onto the couch on her hands and knees. Her ass was perfect, round and firm. I lined up and shoved my cock into her pussy in one hard thrust. She was tight and hot and soaked. She cried out and pushed back against me. I started pounding her right away, no slow build-up. Skin slapped against skin. Her tits swung under her with every thrust.
"Harder," she said. "Fuck your sister harder."
I gripped her hips and slammed into her. Her pussy gripped me like it didn't want to let go. I reached under and rubbed her clit in fast circles. She came quick, shaking and moaning, juices running down my balls. I didn't stop. I kept fucking her through it.
After a minute I pulled out and flipped her onto her back. I wanted to see her face when I filled her. I shoved back in and hooked her legs over my shoulders so I could get deep. Her pussy was red and swollen from the pounding.
I fucked her slow and deep for a few strokes, then picked up speed again.
"Give me that cum," she said, looking right at me. "Pump it deep in my cunt. I want to feel it leaking out of me later."
Her dirty talk pushed me over. I buried myself to the balls and exploded. Thick ropes of cum shot straight into her. I kept thrusting through it, making sure every drop stayed inside. She came again when she felt it, her pussy milking my cock.
I stayed inside her until I started to soften. When I pulled out, a thick white load oozed from her stretched hole. She reached down and scooped some up with her fingers, then licked them clean.
"Again," she said. "I want more."
We moved to the bedroom. She rode me next, bouncing on my cock while I played with her tits. She leaned forward so I could suck her nipples while she ground her clit against me. I came inside her a second time, even deeper than the first. She kept riding until she came too, then collapsed on my chest with my cock still twitching inside her cum-filled pussy.
Later that night she woke me up with her mouth on my dick again. We fucked in the shower, against the wall, water running over us while I pumped another load into her from behind. By morning she was walking funny and my balls were drained, but she still wanted one more round on the kitchen table. I bent her over it and fucked her until I gave her a fourth creampie, watching my cum drip down her thighs onto the floor.
She smiled over her shoulder. "We're doing this every time they're gone."
