Lizzie

The idea of fucking my own sister was just too hot. After all those years of fantasizing about her in my bed at night, wanking off as I imagined plunging my hard cock into my sibling’s pussy, I couldn’t believe it was about to actually become true.

The two girls were still on the couch with their asses in the air. I went over to Lizz and turned her around and got up on the couch next to her and started kissing her. As I did, I let my hands roam freely over her body, feeling up her generous tits and giving special attention to her ass. Her legs were spread wide with mine between hers and my cock was pressing against her ass and pussy. I could feel the heat from her excited cunt against my thighs. I squeezed her big round tits and bent over and whispered in her ear. "You ready for your little brother, big sis?" I asked unnecessarily.

"Ummm, I don’t think you’re so little right now," Lizz grinned up at me, her eyes on my throbbing member.

“Guess you’re about to find out,” I smirked. I put my hands back on her round ass cheeks and pushed back a little so I could line up my hard shaft with her honey hole. She moaned as my long cock slipped into her wet pussy, encouraging me to push harder and deeper.

"Oh god, James I can’t believe my brother is fucking me. You feel so good," she moaned. She wiggled from side to side as I slowly pushed my dick in all the way to the hilt. I held it there a moment just enjoying the warmth and tightness surrounding my throbbing rod. Then I began slowly sliding my cock back and forth inside her hot cunt and she began meeting my thrusts by thrusting her ass back into me. I couldn’t believe that fucking my sister would feel so good. She was so amazing, it didn’t feel wrong at all.

Lizz moaned and looked over her shoulder at me, her eyes slightly glazed. “So you like fucking your big sister doggy style, James?” she asked me. “I can’t believe we didn’t do this before now. You feel so good inside me, bro.” Then she went back to moaning as I rammed her butt, squeezing her ass with one hand and reaching around and massaging a boob with the other.
“Wow, James, I can’t believe you’re actually fucking your own sister,” I heard from over my shoulder. I looked back and saw Ash was leaned back in the other corner of the couch, one hand three fingers deep in her pussy and the other massaging one of her breasts. "I mean I admit that I am somewhat of an exhibitionist but I thought about how hot it would be to watch you fuck somebody else, much less your sister," she smiled.

I turned my attention back to Lizzie and started thrusting harder and faster. I let go of her boob and straightened up again, leaning back as I grabbed her hot ass with both hands and pushed my hips forward, fucking her as deep and hard as I could She was moaning and groaning pretty much uncontrollably and I could tell she was about to get off. I was working so hard now that my shaft was coming out with each out movement with a little popping sound, then sliding easily right back in to her hungry cunt. I felt my balls starting to tingle and knew I was almost there too.

"Oh, oh, fuck, James!" Lizz was literally screaming now. "Oh yes, oh fuck yes! Fuck me hard, brother, fuck me harder! Ohhhhh, yesssssss!"

I plunged my cock in as deep as it would go and held it there as I felt her pussy walls contracting around me and clenching my rod so tight I couldn't move. I felt her warm juices coating my cock deep inside her, then I felt that rush from my balls rising up my shaft and I unloaded jet after jet of hot white cum deep into her womb. I collapsed on top of her and held on tight as I rode the waves of her orgasm one after the other. My head was spinning and I literally didn't know where I was, but I think it was probably heaven.

I was so spent that I had to roll over on my back and lay down next to her as she stretched out and turned onto her side facing me. We were still breathing heavily and sweating a bit. We looked at each other and we both just grinned and laughed. It seemed like it took forever for my dick to finally start to quit swelling and throbbing. It was then I noticed the couch was shaking and I heard the loud moans from the other end as Ashley reached her orgasm too. Lizz and I looked at each other then looked over at Ash. She didn't scream anything, just some very loud moaning and groaning as her whole body quivered. Finally her orgasm subsided and she opened her eyes and looked at us looking at her.

"Wow, that was hot!" she exclaimed. "It got me so hot watching two siblings fuck. I had never thought about it before. It sure got my rocks off too,” she grinned. "So now what?"
