I grabbed my cock and began rubbing the head up and down along her slit, pushing the head a bit deeper with each stroke. Marie reached down to stop my probing and stroking. She held my cock steady, the head inside her. We were in suspended animation for a moment, both somewhat unsure what would happen next.
I pressed my hips forward, and Marie let go, allowing my rigid tool to slip inside her warm, wet pussy. She was tight but so wet that penetration was almost effortless. Marie gasped as I entered her fully, my thick, nine-inch cock stretching her and bottoming out. I held my cock buried deep within her, pressing my pelvis against hers. I leaned down and kissed her deeply, and she returned the kiss with her tongue hungrily exploring my mouth.
I withdrew my cock and immediately plunged it back in as my sister wrapped her arms and legs around me, pulling me hard against her. This would not be a tender love making session; this was fucking — carnal, lustful, passionate fucking.
Marie withdrew her tongue from my mouth long enough to order me to fuck her hard, and then returned to tongue wrestling with me as we fucked. She raised her hips as I plowed my cock into her, our bodies slapping together loudly and the pace of our fucking increasing. I knew I wouldn’t last long, and my mind cleared long enough to remember that this was my sister, and there was no way I could cum inside her.
As I felt my orgasm building, I pulled out and began furiously jerking my cock, pointing it directly at those wonderful tits. Not skipping a beat, Marie sat up, grabbed my cock, and thrust it into her mouth. Apparently, she, too, had an idea of where she wanted my load to land! After maybe 45 seconds of her amazing deep throating and stroking, I released my hot load with a loud grunt and gasp. Marie clasped her lips around my thick cock, swallowing hard and sucking each spurt of semen as my cock unloaded in her hot mouth.
Thoroughly spent, I collapsed on the bed next to my sister. Smiling and licking her lips, she rolled over with her back to me. It was my turn to spoon her, and my still hard cock lodged directly into her wet opening as I curled up around her. It was clear my hardon wasn’t subsiding any time soon, so I eased it further into her, and she welcomingly pushed back, accepting it deep into her wet, gaping pussy.
My arms reached around her, and my hands grabbed Marie’s beautiful tits as I began slowly fucking her from behind. She pulled her top leg up to provide more access, and I pushed deeper, again feeling the head of my cock bottom out inside her. Marie instructed me to hold there and began and rhythmic gyration of her hips bearing down on the head of my cock.
“Don’t move!” she gasped, apparently working up another orgasm. “Oooooo, fuck!!” she moaned and cooed, and I could again feel her legs trembling as her torso shuddered and she pressed down harder while gyrating on my cock. “I’m cumming!!”
“FUCK ME!” she screamed, urging me to return to action. I flipped her onto her stomach and began plowing her deep and hard as she urged me to fuck her even harder and faster. I gripped her hips tightly as I fucked her from behind, our bodies again slapping loudly with each thrust.
