So Wrong But So Right (very dirty)

"Kids come downstairs we are about to go!" I heard my mother yell from the living room. I came out of my room and went downstairs where my mother and step dad were getting their luggage together and i saw my two half brothers and my half sister standing around them. We all helped them get their luggage into the car. When we finished our mother turned to us and hugged us all.
"Alright guys we are gonna miss you, behave yourselfs and take care of each other. We will be in Europe for a couple weeks and we will call in every once and a while okay?"
We all nodded and hugged her back. They got in the car and drove off. We all got back inside and went to our rooms seperately. I laid down on my bed and stared up at the cieling. No parents were going to be around for weeks and i have nothing to do, how sad is that?
I decided to give my best friend Melissa a call to see if she will come over.
"Hello?" Melissa picked up her phone on the 3rd ring.
"Hey girl, i am deathly bored do you want to come over?"
"Yeah sure i will be there in 5 minutes."
I hung up and decided to change my clothes. I put on a sexy lacy purple bra with a small lacy purple thong. On top of that i put on a jean mini skirt and a tank top that really showed off my size D b00bs.
Halfway through high school i realized that i was bi and ever since then i had wanted my best friend. She was so beautiful, she was tall with long wavy red hair that fell down her back and lead to a round bouncy butt. She had mile long legs. She had a tan year-round and big b00bs and lips to die for. I always found myself staring into her eyes as well, they were the lightest shade of green. She would never like me though, i dont even know if she is bi. I looked in the mirror at myself sadly. She was so beautiful and i so was not. I was tall and had big b00bs i guess. I had long curly brunette hair that fell down to my butt. My eyes were a mixture of blue and grey which resembled my mothers eyes as well as my half brother Trevors eyes. Deciding to shrug off my selfconcious thoughts i applied make up and went downstairs to wait for Melissa. Cassidy came down and i saw her surprise when she saw me.
"Why are you dressed like that?" She asked looking me over and i thought i saw her blush but i wasnt sure.
"Melissa is coming over so i just threw something on..." I lied smoothly. No body in my family knew that i was bi thankfully.
"Ok then," Cassidy looked me over one last time and went into the kitchen.
Not a moment later there was a knock at the door and i got up to answer it.
"Hey __" Melissa smiled at me when i opened the door. She looked me up and down and had an amused smile on her face. "Dont tell me you got all dressed up for me?"
I giggled and said "I just threw something on, come on lets go up to my room."
I closed the door behind her and let her lead the way up the stairs. I watched her butt through the small cotton shorts she had on as we walked up to my room. She closed my door behind us and we sat on my bed together.
"__ there is something that i have been meaning to talk to you about...." She looked away from me embarrassed.
"Melissa tell me you know you can tell me anything," I frowned worried and held her hand. It was so warm and soft in mine.
"It would be better if i showed you..." she whispered and looked at my lips briefly before she quickly kissed me. I was in shock but quickly started kissing back. I licked her lips and pushed her back on the bed. It felt so amazing to be kissing her, its all i have wanted for years now. She allowed me entrance to her mouth and i moved my tongue inside licking and sucking on her tongue. She whimpered against my lips and pulled away for air.
"That was better than i ever imagined," she whispered and took off my shirt.
"I cant believe you are bi, i have wanted to do this with you for so long!" I took off her shirt and saw her in a sexy leopard print bra. I moaned out of how sexy she was. I could feel my wet pussy get even more wet to the point where it was soaking my panties. We quickly removed our clothing and started rubbing against each other, exploring each others b0dies. Her pink nipples were hard and sensitive just like mine. I started sucking on them and she was moaning my name like crazy. I kissed down her body until i reached her drenched pink pussy.
I slowly licked it over and over as i rubbed her clit
"Yes! more __ please!" She was moving her hips in rythem to my rubbing.
I shoved 2 fingers deep into her causing her to scream loudly.
Suddenly the door busted open and my half brother Adam came in and stared at us in shock.
"What the hell is going on?" He was staring at our bodies not even embarassed.
"Adam get out, i thought i locked the door," I covered myself with my hands while Melissa quickly got under the covers from embarassment.
"Oh no i'm not leaving now, i was just about to go out but i think being here would be a lot more interesting." He winked and started taking off his shirt, revealing a toned tight 6 pack and large muscles.
"Adam! What are you doing?!" I exclaimed astonished.
"Come on, it's not like we are really brother and sister. Besides i will tell mom what you were doing and im pretty sure she wouldnt like it."
I looked at Melissa with a look of apology on my face and she said its okay.
"Cassidy and Trevor went out so its only us here." Adam said and took off his pants and boxers to reveal his long hard cock. It was at least 9 inches and i felt my mouth drop in surprise.
Adam walked over and sat down on the bed. Melissa and i got down on our knees in front of him. I took his hardness in my hand and started rubbing up and down slowly while Melissa was kissing his lips and he was rubbing her b00bs. I took Adam's c0ck in my mouth and started sucking, taking it deep in my throat and sucking hard and fast. He broke his kiss with Melissa to groan and push my head down so he went deeper in my throat. "Oh fvck __ you know how to suck dick dont you?" He kept pushing my head down more and more not letting me breathe. Melissa moved down inbetween my legs letting me sit on her face. She started licking and fingering my tight wet pussy while i sucked hard and faster and deeper. . I whimpered with Adam still in my mouth. I felt myself about to cum as i felt Adam's cock pulse in my mouth. He came a huge load of hot cum in my throat and i swallowed every drop as i came all over Melissa's face. I took Adam out of my mouth and Melissa had just sat up licking my wetness off her face when her cellphone started to ring.
"Hello?" She answered and was disappointed when it was her dad asking her to come back home.
"Okay dad, bye." She hung up and regretfully started pulling on her clothes. "Sorry guys i have to get home but maybe we can continue another time." She winked at us and left. I looked up at Adam with a blush on my face im sure. "I cant believe we just did that...." I said embarassed.
"Hey, dont think im done with you yet." Adam lifted me up and laid me down on the bed under him.
"Adam no stop!" I paniced and tried pushing him away but with him being so strong it was like pushing a wall.
"Why? You already sucked me off, whats the problem??" He was licking my nipples and making them hard, which caused me to whimper even though i tried not to. I tried to shove him off again but my efforts werent as strong. I felt his huge hard cock against my thigh and i shivered in anticipation. "I'm a virgin..." I whispered shyly.
He stopped cold and looked at me in surprise. "You arent kidding??"
I shook my head and he surprised me with a hard kiss. It felt so wrong but it felt too good to stop! I could feel my nipples get harder and my pussy get more wet just from kissing him. He positioned himself and pushed forward hard and quick causing me to scream so loud. "Adam! uh!" I dug my nails into his back and screamed as i felt myself being stretched with his entire length all the way inside me. My virgin blood and wetness was dripping out of me. I had never felt something so good yet so painful in my life. "Fvck, __ you are so damn tight!" He started thrusting forward over and over making me whimper even more when the pain gave way to imense amounts of unyielding pleasure!
"Harder Adam!" Adam pushed into me over and over with every inch of him going inside, stretching my tight little pussy
"I'm gonna cum ___!" With a few more strong deep thrusts he blew his load inside of me and i came with him. I could feel his load filling up my womb while my wetness flowed down his shaft. With both of us exhausted he got off of me and laid next to me. We looked at each and he kissed me slowly and softly. "No one will know okay?" He whispered.
I nodded in agreement and he got up. "Hold on okay? i will be right back" He went into my bathroom and wet a rag. He wiped off his dick and brought it out and cleaned up my wetness and the blood.
"There," he said as he sat on the side of the bed. I tried to move but winced when my legs and my private aread throbbed in complaint. "Dont move, you are gonna be sore for a little while, go to sleep or something." I nodded and rolled over on my side. I heard him leave the room and close the door behind him. My mind was racing with anxious thoughts.
I just had sex with my half brother!
