Luke traced the design on my white lace thong with his thumb lightly, as I just sat there with my mouth gaped open and still stunned by all of this happening. Olivia was standing with her back against the refrigerator with the same dumbfounded look as me. I could see her fiddling with the bottom part of her grey oversized t-shirt.

After a little while, I shut my mouth and lightly bit my lip as I felt myself slowly get hornier. I looked up at him lustfully and he took that as an okay. The next thing I knew his arms wrapped around me and pulled me closer, as our mouth desperately connected.

He licked along my lower lip asking for entrance which I didn't let him have immediately, but when I didn't, he squeezed my ass which caused me to gasp and part my lips enough for him to snake his tongue into my mouth. He was honestly an amazing kisser, our tongues massaged each other for what felt like hours, before I realized Olivia was still here. I felt a blush creep up my face as I slowly pulled away from Luke, and whispered softly before looking up, "That was amazing. I've wanted you to do that for so long."

"I wanted to..." he replied.

I looked up to see Olivia was no longer in the room. I felt a little guilty briefly, but next thing I knew Luke's lips were on mine again and I could feel his erection lightly pressing again my thong. His hands slid up my waist until they found my boobs, with no bra on and cupped them softly, before giving them a light squeeze. I moaned and he kissed across my jawline and down my neck, sucking softly on a sensitive part. I tilted my head to give him more access, as he sucked on my neck and played with my breasts.

Slowly, one hand found its way the side of my thong and he gave it a light tug before I shook my head and stopped him. He raised his eyebrows in a challenging way at me.

"Lets go get Olivia..." I whispered with an innocent voice and he lifted me, bridal style, and carried me to her room.

As we approached the door, I wiggled out of his arms and he whispered hotly into my ear, "You're lucky I was going to put you down anyways."

I shivered a little as a blush crept to my cheeks. I pushed the door open and walked to the bed with Luke trailing close behind.

"I was coming back down..." Olivia said, with a slight shrug.

I had turned my back briefly, to walk to the other side of the bed and when I turned back around I saw Olivia and Luke making out passionately. I felt my pussy become a little wetter as I watched brother and sister kiss, with Luke completely dominating her mouth. I climbed onto the bed, bringing them back to this world. I gave them both an innocent look not sure where to go from here.

"Kiss," Luke ordered.

I loved being dominated and I guess Olivia did too, because her mouth was covering mine in no time. We didn't waste any time. We immediately began making out, lustfully. I felt the bed dip and Luke sitting behind me. He was sucking on my neck and teasing my nipples as we made out. Being in between the two, like I was, I felt like a doll being used by them both and I loved it.

Slowly, I felt Luke's hands creep lower and he pulled my shirt off over my head and Olivia moved her head down to start sucking on my already hard nipples.

After he had pulled my shirt off he had his and Olivia's off in no time. I moved my hands low against him and pulled his pants off, Olivia looked up to watch and saw his seven inch erection peaking out of his boxers.

Both of us were fascinated by his large cock and both of us needed to taste it. I massaged the tip with my tongue and rubbed up and down his shaft slowly and Olivia sucked and played with his balls. I moved my hand and Olivia gave attention to his shaft and I gave attention to the sensitive tip licking up all the precum that was now coming out and we both fondled his balls. Every few minutes Olivia and I would stop to kiss hotly and I had a feeling she could taste the pre-cum on my lips.

Luke slipped my thong off and got to work eating me out as Olivia watched and played with her wet pussy. His tongue teased along my inner thighs and I whimpered softly wanting his tongue closer. Painfully slowly his tongue made its way to my pussy lips and he pushed my legs further apart licking all along my clit. He slipped a finger inside my young tight pussy and sucked on my clit.

Olivia climbed on top of me and straddled my face. I licked along her slit to her clit and sucked on it, rubbing my tongue along it only stopping to moan occasionally. I could tell Olivia was going to cum soon, so I slipped a finger into her and felt Luke stop eating me out and felt something new pushing against my pussy.

Slow and carefully Luke's seven inch cock slipped into me and I whimpered softly from the pain as my hymen broke and my pussy stretched to fit his thick cock inside me. Eventually the pain was replaced by pleasure and he sped up his thrusting in and out of me forcefully. I went back to licking up all of Olivia's juices. I felt Luke's cock hitting my womb and his balls smacking against my ass, which I knew would leave a red mark in the morning. I felt her juices dripping down my chin.

Luke rubbed my clit as he fucked me hard and fast, letting out a few grunts. Quickly, Olivia starting grinding against my face moaning and yelling, "I'm gonna... I'm gonna cum! I'm coming!" And she did. I licked her pussy clean as she laid on the bed trying to catch her breath, but once she did, she sucked my clit as Luke kept fucking me.

"Fuck me, harder!" I moaned and he did as I said. Now, with the attention I was getting from both brother and sister I could feel I was getting close and I was moaning louder. I arched my back and moaned loudly, "I'm going to cum!"

I felt my pussy tightening as my legs tensed and I came all over Luke's cock. My orgasm had me out of breath but it pushed Luke to the edge and he came hard inside me, leaving me dripping his seed.

We all fell asleep naked together, but I had a feeling this wouldn't be the last time we all did this...
