AU: This is my first story so please leave reviews to help me make my stories better. Flames included :D I am planning on making this fanfic 3 chapters… but it might be longer. Who know when the plot bunny attacks? I wanted to post this later when I was done, but I decided to post it now :D

Don't Leave Me… Please

Sasuke Uchiha stared up at the ceiling after having another wet dream. 'Oh God, what's wrong with me? I shouldn't be dreaming about things like that! He's my brother!' He mentally scolded himself. 17 year old Sasuke had remembered the dream clearly. His aniki's hands were roaming his body and touching him everywhere. Itachi was dipping his tongue into Sasuke's navel. Fingers tweaked his nipples and trailed lower and lower. He woke up at that point.

Sasuke went into the bathroom that was connected to his room and took a shower. He got dressed and headed outside to greet his aniki. "Hello, otouto," Itachi greeted him with coffee in his hands and a book in the other. His face was faced at the book, so he didn't notice the blush that Sasuke sported across his face. Or did he? "H-Hello, aniki," Sasuke replied shyly. Itachi put down his book and went to put the cup in the sink. He turned towards Sasuke and said, "Do you want to go out with me today?" "Sure, aniki," Sasuke replied. "Good," Itachi replied with a smile. "I was going to make you go if you didn't agree."

After a few minutes, they got into Itachi's Nissan (pun intended) and Itachi started driving towards the park. "Hey Sasuke," He asked. "What do you want for your birthday?" Sasuke hesitated before answering, "I don't want anything, aniki." Itachi sure as hell didn't believe him so he kept interrogating Sasuke with questions. "Are you sure, otouto?" "Yes, aniki. I don't want anything." 'Except for your love.' Sasuke replied but without saying the last part. "I'm sure I'll find you something, Sasuke." The elder Uchiha said with a smirk playing on his face.

*****Itachi's POV*****

We got out of the car and I opened the door for him. "You don't have to open the door for me, Itachi." He replied. "I'm not a girl!" I chuckled lightly and replied by saying, "Of course you're not." He rolled his eyes and stepped out of the car. I loved the way he acts sometimes. He's so cute and adorable. I just want to eat him up… literally. 'Oh God, I shouldn't be thinking about things like that. He's my brother… and he might think that it's disgusting and never want to look at me again.' I looked up at his angelic face and smiled. We decided to go for a stroll down the park. He held my hand just like we did when he was younger. At first I was surprised. I never expected him to hold my hand. Not that I don't want it! It's quite the opposite. I wanted his affection and would love if he would give that to me every day…

*****Sasuke's POV*****

I took hold of my beautiful nii-san's hand as we started walking though the park. I ignored all the disgusting glares that were sent at our way. Apparently, they thought we were a couple… I wish that was true. We listened to the birds and children laughing and playing in the park. Good thing that it was summer break, so I could spend more time with Itachi. I realized that it was only five more days until my birthday, which was Saturday. Wait! Today is Monday! Why isn't Itachi working? At age 23, I'm sure that he has to work! I asked him, "Hey Itachi-Nii, why aren't you working? It's Monday, isn't it?" "I'm not working because I'm way ahead of the paperwork, so I asked for a two month vacation. I wanted to spend more time with you." He answered with a smile on his kissable lips. I suddenly felt like I was on top of the world when he said that to me. I wanted to ask him so many questions, so I collected my thoughts and started bombarding him with loads of questions.

*****Ryoku*****

*****Itachi's POV*****

"Why don't you have a girlfriend?" Sasuke asked me curiously. I furrowed my brows and wondered why he wanted to ask me that. So, I asked him, "Why do you ask that, otouto?" He hesitated a bit and said after a long pause, "Because Nii-san, you're so beautiful. Your hair is so soft and silky, you're so kind and I can't think of anyone that wouldn't want to date you." I was shocked and I'm sure it showed on my features. I quickly regained my composure and answered back to him saying, "I'm flattered that you think I'm beautiful, otouto. The reason that I'm not dating anyone is because I'm gay and the person that I want is someone that I could never have. So, why aren't you dating anyone? You're beautiful as well." Now it was his turn to stare in shock. His mouth hung open and he just stared at me. He looked down at the floor and said quietly, almost inaudible and said, "I'm gay too. The reason I'm not dating anyone is because the person that I want is someone that I can't have too." I saw a small blush spread across his face.

I kept thinking about his words as we continued our walk. 'Someone I can't have' what could that mean? Could he be talking about me? I shook my head and tried to remove the thought from my head. He couldn't possibly be talking about me… could he? No, that's just my wishful thinking. But, who else could it be? I have to think about it some more.

I saw an ice-cream truck decorated in so many colors that it was a miracle it didn't make all the drivers on the road go blind! I looked at my brother, whose dark eyes lit up. This meant that he saw it too. I chuckled and asked him if he wanted some and he replied "Yes" enthusiastically. We approached the truck and I spotted my friend Deidara and Sasori in the truck. I always knew that they sold ice-cream in their spare time. I also knew that they were lovers and they knew that I loved Sasuke with all my heart. We approached the ice-cream truck and we greeted them with a "Hi." They said hi too and asked us what flavor of ice-cream we would like. Sasuke and I said "Chocolate" simultaneously. We looked at each other and started laughing. I looked out of the corner of my eye and saw Deidara whispering to Sasori. I knew they were planning something.

Deidara said, "I'm sorry, we are all out of that flavor. We only have enough for one person." I clearly saw that there was a whole tub of chocolate ice-cream in the back. I didn't say anything as I had caught onto their little game. I replied by asking Sasuke, "Do you mind sharing one with me, otouto?" He answered me a little hesitantly before saying, "S-sure, aniki. I don't mind." I turned towards Deidara and Sasori and said, "Then we'll have one chocolate ice-cream cone." I saw Deidara smirk and replied with a "Coming right up!" A few seconds later, he handed us the dairy treat and I paid him and added a little tip for his deed. As we started walking away, I mouthed the words 'thank you' towards them. Luckily, Sasuke didn't see.

We took a seat beside a tree because the benches were all full. I sat down first and I expected Sasuke to sit beside me, but instead he sits right between my legs. I didn't say anything because I actually liked the position that we were in. He braced his back against my chest and relaxed as I wrapped an arm around his smaller frame.

I licked the ice-cream and put it next to his mouth for him to take a lick. He licked it and I just stared at him while he did that. I brought it up to my mouth and started licking on it. I heard him yell, "Hey! No fair aniki! You're getting more that me!" I teasingly ignored him as I continued licking it. He turned his head and faced me with an angry look on his face. The next thing that he did took me by surprise. He started licking the ice-cream the same time that I did. He didn't seem to mind and I certainly didn't mind. I continued licking it and then… our tongues touched!

His tongue was so soft and warm. I did what felt right and I captured his lips in a soft and passionate kiss. He gasped in shock and I took the opportunity to attack his open mouth with my tongue. He shyly kissed me back and we ended up battling for dominance. His hands slowly reached up and untied my hair. He softly played and tugged with it. I threw the cone somewhere and wrapped my arms around his torso and brought him closer to me as he wrapped his slim legs around my waist. We broke apart for much needed air and only then had I noticed that we were in a park.

Everyone was staring at us! The children's eyes were being shielded by their mother's hands. The women were drooling… stupid yaoi fan girls! The teenage girls held cameras in their hands with drool going down their faces and the teenage boys all had a tent in their pants! No adult men were there… they're probably at work. I felt relief wash over me as I noticed that none of them knew me and Sasuke. I looked down at Sasuke and saw fear in his eyes. My heart stopped. Oh no… does he regret it? Does he hate me? Does he… fear me? I got up and helped him to slowly get up afterwards. I walked out of the park and outstretched my hands for Sasuke to take the keys to my car. I told him to drive home by himself. I needed some time to think.

I took a taxi home and greeted my mother and father as I went into the house. I didn't see Sasuke, so I assumed that he was in his room. Oh god, I blew it didn't I? He must hate me. My father told me that he wanted to speak to me and I quietly entered his luxurious office. Father was situated at his desk, located near the back wall. He greeted me by saying, "Itachi, you are 23 years old. You should be thinking about getting married and not about you annoying little brother!" I expected him to say that. Fugaku and Mikoto hated Sasuke and thought that he was a mistake. I thought that my beautiful baby brother was a gift from god!

To make Fugaku feel better, I lied and said, "Sure Fugaku, I'll think about getting married later." I only want Sasuke. What astonished me was what he said next, "You don't have to. We've picked out a bride and you're getting married to her on Sunday. After that, you can take over my business." "What?" I replied in anger, "I'm not marrying someone that I don't even know! Plus, Sunday is the day after Sasuke's birthday. I was planning on spending my weekend with him!" He silenced me and said, "I don't want to hear anymore about your stupid brother! You are going to get married and seeing that you love your brother so much, I will hurt him if you don't get married! Is that understood?" I had been defeated. I would give up my freedom for Sasuke's freedom. I would even catch a grenade for him. Jump in front of a train for him. Take a bullet straight to my brain for him. I would even die for him. I nodded my head and saw Fugaku smirk triumphantly. I left the office to go and cry in my room. Yes, I did say cry.

I walked pass Sasuke room and overheard him crying. Why was he crying? Was it because of what I did? I don't want to cause him anymore pain. I'll get married and he'll never have to see me again. I'll avoid him until the day I get married. I told myself over and over again, but I couldn't bring myself to leave him. I loved him! But, I love him so much that I don't want to hurt him.

*****Sasuke's Birthday*****

I evaded Sasuke this entire week. It was Sasuke's birthday and since I'm getting married to someone that I never met, I want to confront Sasuke. I want to ask him what he thinks of me and I want him to know what I feel for him. I'm getting married tomorrow and if I know Sasuke's feelings towards me, then I'll live my life without wondering what COULD have happened. Sasuke doesn't know that I'm getting married, but he'll know soon enough.

I entered Sasuke's bedroom and saw him asleep on his bed. The dark blue sheets contrasted well against the black walls and Sasuke's snow-white skin. He looked so beautiful… like an angel sent from heaven. I sat beside his sleeping form and the bed slightly dipped below my weight. I ran my hands through his soft, smooth hair and at the contact, his dark eyes opened. He sleepily asked me, "A-aniki? What are you doing?" I replied by quietly saying, "I'm sorry, otouto. I'll stop, but I want to ask you a few questions." "No aniki! That's not what I meant. Please don't stop," He answered back at me with panic clearly visible in those beautiful onyx orbs. "Don't worry, I won't stop," I said while I continued to stroke his hair.

I wanted to desperately get these questions out, so I started asking them, "What do you think of me, Sasuke?" He turned to stare at the ceiling for a long time that seemed like forever in his presence. He blinked a few times before finally saying the three words that my heart ached for, "I love you." I stared at him in shock with my mouth slightly open. I quickly closed it before he noticed. "Please don't be angry with me, aniki. I love you and I always have. I probably shouldn't have licked the ice-cream the same time as you. I'm sorry. Please don't hit me like Father does," He said with tears brimming his eyes. Salty tears started streaming down his face and I quickly brought my hand up to wipe them away. When I did that, I asked him a question that was plaguing my mind, "I'm not angry at you, otouto. I love you too. I'm so happy that you feel the same way as I do." I paused for a moment and stared at the relief clearly showing in his eyes.

I finally asked my question, "Father beats you?" Fear appeared in his eyes as he said, "I'm not supposed to tell anyone about it… especially you." I wanted to know what has been going on in my Sasuke's life, so I continued speaking and said, "Please Sasuke, tell me. I want to know. I love you so much and I want to now what has been going on. When did it start? Please Sasuke, tell me."

He stared at me, seeming to be contemplating something. "O-okay, b-but please d-don't tell a-anyone." He replied in between sobs. "F-Father has been b-beating me ever since I turned 12. He said that it was my fault that you never thought about getting a girlfriend and continuing the Uchiha lineage. I never understood what he meant. He kept coming home and beating me. I loved spending my time with you and I didn't want you to find my scars. Father normally hits my back, so it's easy to cover up. But, that doesn't stop the pain that I constantly feel. When I turned 13, I started developing more-than-brotherly feelings for you. I adored everything about you and I never wanted to leave your side. I was like an attention-starved kid."

I stared at Sasuke as I soaked in all of this information. I wanted to kill Fugaku, but I couldn't since he is the head of the Konoha Police Department. I could end up going to jail and leaving Sasuke. How could I let this happen? Why didn't I notice? I should have stopped this! I suddenly remembered that Sasuke was crying in his room on the day that I kissed him, so I asked him, "Why did you cry on the day that we kissed?" He looked at me with his innocent eyes and said, "I was afraid that I did something wrong and that you could never love me. I was afraid of rejection. The one person that I ever loved didn't love me back." I looked at him and offered him a small smile as I said, "I'll always love you, otouto… if you'll accept me as a lover." He blushed and nodded his head saying, "I'll never deny you Itachi."

I leaned in and kissed his pink lips. His lips felt so soft, so warm and so delicious. I ran my tongue along his lower lip and he opened his mouth shyly. I glided my tongue across his mouth in different directions, mapping it out in my head. I earned a moan from him and his arms shot up into my untied hair. I pulled the sheets away from him and wrapped his legs around my waist. Sasuke got more demanding and pushed his slick appendage against mine. I pushed him down unto the bed. He kept his legs wrapped around my torso and grinding his erection into mine. I elicited a moan and started to unbutton Sasuke's shirt. I finally got his shirt off and I started to run my hands along his chest. His skin was flawless. It was visible that he had muscles, but not so much that he was bulky. He was lean and had a smaller frame than mine.

I kissed down his jaw line and stopped at his pulse. I kissed it and bit into his flesh, marking him as mine and mine alone. He screamed in half pain and pleasure. I kissed down his chest and played with one of his nipples. He moaned wantonly and screamed, "Itachi!" I smirked and played with his other nipple with my finger. I kissed further down his chest and dipped my tongue into his navel and mimicked motions soon to come. I brought my face up and looked at his face, as if I was asking for approval.

He nodded his head and I pulled down his boxers and stared in awe at his penis. It was larger than I imagined it would be, but it wasn't as big as mine. He blushed and tugged at my shirt. I took the hint and pulled off my shirt along with my black jeans and boxers. Now it was his turn to stare. He looked at my penis with an equal amount of awe as when I looked at his, perhaps even more. I moved back unto the bed and separated his legs. I asked him, "Sasuke, are you still a virgin? You don't have to worry; this is my first time too." I was a bit embarrassed at my statement. I never wanted to touch or be touched by someone other than Sasuke. So, I remained a virgin. Sasuke nodded and shyly said, "Yes, I'm still a virgin. Please take care of me." I kissed his forehead and said lovingly, "Always." I put my hands up to kiss mouth and said, "Suck." He took my three fingers into his mouth and coated them with saliva. I slid one of my fingers into his tight hole and he arched his back. I slid it in and out of him and then I added a second finger. He got used to two fingers and I added a third one. He screamed in pain and I kissed him on the lips and I whispered to him, "Shhh, its okay. I'll take care of you." He nodded and I pushed my fingers in and out of his virgin hole. I hit his prostate and he screamed in pain and yelled my name.

I took my fingers out and placed my erection close to his entrance. I looked at his face and asked him, "Can I?" He nodded and said, "Take me." I didn't want to cause him any pain. I pushed my erection into his once virgin hole and he screamed in pain. He started digging into my back with his nails. I hit his prostrate and he moaned. I slung his legs over my shoulders and went deeper into him. I hit his prostrate over and over again until he didn't fell any more pain, just pure pleasure. I took his erection into my hand and started stroking and pumping it. The room was filled with moans, pants and screams as we hit our climaxes. He came onto our chests and I came deep inside him, marking him as mine. I pulled out of him and pulled him in between my legs. I whispered to him, "I love you." He whispered back, "I love you too, aniki." We fell into a deep slumber in each other's arms.

We woke up several hours later after our *cough* activities. I looked at the digital clock located beside Sasuke's bed stand and it read 6:53. I kissed his forehead and he slowly stirred awake. I said to him, "I love you. Never forget about this." He smiled innocently and said, "I love you too, aniki. What do you mean? Won't we always be together?" Now was time for the truth to be revealed. Now was the time for sorrow, grief and loss. "I'm sorry, otouto. I'm getting married tomorrow," I said with pain showing in my voice. I hung my head in shame and waited for what was about to come. He looked at me with anger and jumped out of my arms. He said with anger and sorrow, "What! Y-you're getting married? B-but… why? Did everything that we just did mean nothing to you?" Tears started flowing freely down his face and dropping unto the sheets as he looked down. I took his chin into my hands and turned his face to look at me and said, "I love you, otouto. I'll never forget what we just did. It meant so much to me. But…I have to get married tomorrow. You have to understand." My heart pained me as I said this. "Oh I understand, Itachi. I understand perfectly well that you used me. You took advantage of my feelings." He got off of the bed and started putting on his clothes. I slowly started to get up and said, "Sasuke, don't leave-" He cut me off and said, "I don't want to hear it, Itachi. J-just leave me alone!" I ran to him and trapped him in my arms. He started yelling, screaming and thrashing at me. "Let me go!" He yelled. "No." I replied. He pushed me away from him with all the strength he had and said, "I hate you, Itachi! I never want to see you again! Get out of my life!"

*****Sasuke's POV*****

I marched out of my room and harshly shut the door behind me. I ran out of the house. I needed a long walk… away from Itachi. I reached the lake that was close to the house and started thinking. 'How could he do this to me? Why did he do this to me? I hate him. No! I love him! I love him so much that I hate him. I want to tell him how I feel. How much I love him! But, he hated me. He used me. I never want to see him again!' I thought while ignoring the throbbing pain of my heart. 'I'm going run away.'

*****Ryoku*****

*****Itachi's POV*****

'He doesn't understand! He just doesn't understand! I'm doing this all for his safety!' I thought as I cried myself to sleep. 'I'm such an idiot!'
