I slammed the door behind me, still pissed from the family dinner, when my sister Lisa cornered me in the hallway. She was twenty-two, same as me, but tonight she looked different—short skirt, no bra under that tight tank top, nipples already poking out.
"Jake, you can't keep staring at me like that all night," she said, voice low and dirty. "Mom and Dad are asleep. You want this or not?"
I grabbed her wrist and pulled her into my room. "Shut the fuck up and get on the bed."
She grinned and dropped to her knees instead. Her hands went straight for my belt. "Been thinking about your cock since you moved back home. Free incest sex story time, right? Just us."
Lisa yanked my jeans down and my dick sprang out, already hard. She wrapped her lips around the head and sucked hard, no teasing. Spit ran down my shaft as she took me deep, gagging once but not stopping. I thrust into her mouth, hands in her hair, fucking her face like I'd wanted to for years.
"Jesus, sis, your mouth is so fucking wet," I growled. She moaned around my cock, one hand rubbing her own pussy under the skirt. I could smell how turned on she was.
I pulled her up, spun her around, and bent her over the bed. No panties. Her ass was perfect, round and waiting. I slapped it once, then shoved two fingers straight into her soaked cunt. She was dripping.
"Fuck me already," she begged. "I want my brother's dick inside me."
I lined up and slammed in balls-deep in one thrust. She was tight, hot, and clenching around me. I started pounding her hard, the bed creaking, skin slapping. Lisa pushed back, meeting every stroke.
"Harder," she hissed. "Make it hurt a little. Been waiting too long for this free incest fuck."
I reached under and pinched her clit while I railed her. Her pussy spasmed, and she came fast, biting the pillow to stay quiet. I didn't stop. I flipped her onto her back, hooked her legs over my shoulders, and kept driving in. Her tits bounced with every thrust. I leaned down and sucked one nipple hard while my cock stretched her open.
She grabbed my face and kissed me messy, tongues sliding, tasting herself on me. "Cum in me," she whispered against my mouth. "Fill your sister's pussy. Do it."
That pushed me over. I buried myself to the hilt and unloaded, pumping thick ropes deep inside her. She came again, walls milking me dry.
We stayed locked together, breathing hard. Lisa smiled up at me, lazy and satisfied. "Round two in ten minutes. This time I ride you."
I was already getting hard again inside her. No going back now.
