I still remember the day when she walked into the kitchen in a bikini. It was white g-string bikini. It looked completely sexy on her. I was 14 when it happened and honestly i loved it. There were instances over the next few years where I would catch myself looking. Sarah continued to grow up. Her legs became long and slender, but muscular and powerful at the same time. Her breasts were bigger and I could see her nipples through her shirts when she didn't wear a bra around the house. The summer before she was a senior in high school was an extremely hot one. We would lay on the cold, concrete basement floor. She wore just a wife beater and tiny shorts that barely covered her perfect ass. When she lay on her stomach, I could see the perfect curvature from the small of her back down to the curve of the foot. But I felt sick. This was my baby sister. Shouldn't have evolution somehow extinguished all of her attractiveness in my eyes? But she was undeniable. Her young body was electric. She would wear low rise jeans and my body would ache with sexual frustration because I could just imagine what was a few inches lower and how badly I wanted to lick every bit of it.

Guys drooled over her, but she was hard to get. She was 24 when she started dating Derek in November. He was a bit of a jock, and the thought of him touching her disgusted me.

It was vacation time and our parents went out with another couple.They always stayed out late with them and drank so Sarah and I knew they wouldn't be back until 2 or 3 in the morning. Sarah came downstairs in super tight jeans and black midriff tank top.

"Woah, what are you wearing?"

"Uh, jeans and a tank top?"

"Sarah, come on, he's going to think you're easy."

"Jesus, relax. I'll do whatever I want with him." She could tell I was upset so she jokingly batted her eyelids. "Don't be upset little brother. You can beat him up for me if you have to." She playfully started punching my shoulder and my stomach.

"Haha, okay, I get it. You can take care of yourself." She didn't stop punching me even after I said that.

"Fight back, Stan. Come on, show me what you got." She had this devious twinkle in her eye. Was she flirting with me? I wasn't sure. I playfully picked her up and gently threw her on the ground. She was still punching me and laughing and hardly noticed I was now straddling her. Her chest was moving up and down with heavy breaths and I had to use all my willpower not to reach out and touch her breasts.

Then, the doorbell rang and we suddenly snapped out of it. She looked at me a little strange and I got off of her.

here!" I watched as she ran to the door, and I sat on the ground hungrier than I'd ever been.

"Hey dude, how are you?" Derek asked when he walked in.

"Good man, just chilling. Probably going to take it easy tonight."

"Nice, well, it was good to see you."

"Yeah, same. What are you guys planning for tonight?"

Sarah interjected. "We're just going to stay here, I think. Watch a movie in my room, maybe."

In her room? Fuck no. "Oh you guys can watch it out here. I'll probably play videogames in my room."

"Thanks Stan, but that's okay. I want to show him some of my pictures and stuff in my room anyway."

"Oh, for sure. Well, I'll be upstairs. Nice seeing you Derek."

"Yeah, same, man."

About an hour had passed and I was going insane. I couldn't distract myself with a movie or the internet or anything. All I could think about was Derek taking my sister's clothes off. Fuck, I wanted to be doing that instead of him

I decided to go near her room. I was little surprised when i saw that she left the door little open. She was fully clothed, but Derek had his pants down and stood at the foot of her bed. I couldn't watch, it was so wrong. But I couldn't stop.

Suddenly Sarah got on her knees. Oh my God, I thought. She took Derek's dick in one hand and licked the other and started stroking him. I was instantly hard. He wasn't as big as me, but he was a good size. Before I knew it, she started licking him all over, swirling her tongue on the tip of his erection and he grabbed her head. Finally, she took him completely in her mouth and i could see he was trying hard not to cum immediately.

She went up and down and her perfect light-red lips caressed him. She started going faster and gently massaged his balls with her hand. I could feel the blood flowing to my dick even more than before. She looked so animalistic in her execution, and I could tell she was getting off on how much Derek was getting off. Finally, she took him the deepest she possibly could into her mouth and he threw his head back and clenched her hair even harder. He started pumping his hips and Sarah never missed a beat. She kept going until he was completely finished and from what I could see, she swallowed without so much as a second thought. She got up and lightly kissed him on the lips and went into her bathroom.

Holy shit. I had never been more turned on in my entire life. It was the most erotic scene I had ever witnessed. And it was my big sister. I had no fucking clue how to handle my feelings. No, my needs. I needed her so badly.

I turned on a cold shower and got in. I couldn't masturbate, not to the thought of Sarah. It was just too weird. I thought I was some sick psychopath.

A couple of days passed, and I tried to keep my distance. I stayed in my room, ignored her calls, avoided watching movies with her like we usually did. But she noticed.

"Okay, so what is the deal? You've been fucking weird lately. Are you depressed or something? You hardly say a word anymore."

"Um, no, I'm fine. Just a little stressed out with college stuff, I guess."

"Oh. Well, don't take it out on! I still want to hang with you, so please don't shut me out, okay?"
She looked at me with her electric blue eyes when she said that.

"Okay, I'll try not to."

"Good. So what are you doing tonight? It's Friday after all don't you have a date?"

My cheeks flushed. "Nah, I'm not really into anyone right now."

Sarah got a coy smile on her face. "Well that's too bad. Because I know a lot of girls who are into you. They ask me about you, you know."

I did know. I wasn't one to brag, but i have developed during these years. At the age of 17 I had a tall, slender but muscular frame and the same cocoa-colored skin Sarah had. I had dark black hair and pale green eyes. Always a winning combination with girls. And I played the guitar pretty damn well, so it wasn't too hard to get a girl interested. But I was never interested. I spent lot of my time lusting after forbidden fruit. I guess it's human nature to want what everyone insists you can't have.

"Yeah? Well, I'm not really feeling anyone at my school. And what about you? How's your loser />
"Come on, he's not a loser, Stan."

"I know, I'm just giving you a hard time. But, be honest, are you really into him, like as a long-term />
"Hmm, probably not. Don't tell anyone," she giggled. "I just kind of wanted, to you know, explore a little."

I felt my face burn. I knew she was doing plenty of that.

"Does that freak you out? That I just said that? Sorry, that was weird of me. Oh my God, I'm so />
She covered her face with one of the pillows on the couch.

"No, Sarah, stop it," I laughed a little. "Don't be embarrassed. That's totally normal. Just, just don't have sex with him" She wouldn't take the pillow off, so I started tugging at it. She giggled, and resisted, so I tickled her stomach.

"Oh my God, stop!" she yelled. I kept tickling her and we were suddenly on the ground. As we fell she had me pinned . She slowly stopped laughing and breathed a little heavy. I could see her nipples through her white tank top and her hip bones jutted out of her black skinny jeans.

She had each of my hands pinned to the ground on either side of my head.

"Okay, okay you win. But ?"

"It’s a good thing that you have accepted your defeat" She laughed.

“Can i ask you something? “

/>
“ Do you think you could kind of, I don't know, tell me what it's like?”

“tell you about?”

/>
“What it’s like?”

/>
"Um, well, okay. Let's see, sex is electric. It's warm, it's this animalistic need to get inside someone or get someone as deep inside of you as possible. There's so much friction, it's kind of a total blur, really. It's like a dream sometimes. It's this rush and this pressure and then, it feels like this insane explosion of pleasure that sends shivers over your body." I sensed that she had gone into her own world when she started talking .After sometime she probably realized that she had said way too much to her baby brother.

I looked at her and her chest was flushed with color. I could feel her breathing heavier.

Before i can realize her chest was pressing against mine and her face was right in front of me. In a moment her soft lips touched mine. I kissed her so hard and so intensely before I realized what we were doing. My dick was aching with blood flow.

"Fuck," I uttered, "What are we doing, Sarah, you're my sister."

"Oh my God, I know, I know, do you not want this? I have and I thought maybe you, fuck. Oh my God I'm an idiot."

"No, no you're not. I wanted this so badly, it just felt so wrong."

"I know, but please don't stop."

With those words I pushed my entire body against hers and grinded my hips into hers. I kissed her neck and ears and arms and sucked on her fingers as she bit her lip.

"I want you out of your clothes. Now," I said. I felt like an animal had taken over my body. I ripped her thin white tank top off and unzipped her black pants and immediately started licking her pussy.

"Oh, oh my God," Sarah moaned and dug her fingers into the living room carpet. I tore my shirt off and she scratched her nails all the way down my back and I shivered in ecstasy. I looked at my sister and I'd never wanted to be so fucking deep in a girl before. I unbuttoned my pants and this time i pinned her down on the floor with all my body weight.

"Jesus christ, Sarah," I moaned in her ear. "I've wanted to fuck you for such a long time. But i cant. And you're my sister." I said all this as the tip of my aching dick just barely touched the outside of her pussy. She was hot with sweat and breathing heavily in my ear. "Fuck, fuck. I can't do this. It is just way too wrong." I started to pull away, but Sarah clasped her arms around my back and wrapped her legs around my waist tightly.

"No," she gasped. "I want you to fuck me so badly, Stan. Fucking do it."

My dick got absolutely rock hard with her words. I immediately used my saliva to lubricate my finger and stuck it in as shrieked with pleasure. I rubbed the tip of my dick around her pussy as she bit her lips in utter anticipation.

"Oh my God, fuck me, please, please, do it now."

I pushed in hard and felt the flesh of pussy for the very first time. She dug her nails into my back and moaned. I pulled out slowly and started to work it in. She rocked with me in perfect motion.

"Jesus, your dick is so big," she said. "I don't know if it will fit."

"It will fit. Just move with me." I worked in and out slowly for a few minutes until finally an insane wave of pleasure came over me. I was finally in as deep as possible and I had never felt a tighter grip around my dick. I put one hand under her back and grabbed her hair with the other and started fucking her with long, hard strokes.

"Jesus fucking Christ, you're so hot Sarah. Oh my God."

We moaned in unison for what felt like forever as our bodies moved rhythmically. All of a sudden, I could feel muscles clench and grip me even tighter and she pushed her hands harder into my back.

"Oh fuck, Stan, I'm going to cum."

"Fuck yeah, say my name when you cum."

She let out a loud moan that echoed through the empty house. "Fuck, fuck Stan, oh my God, Stan."

I could feel myself getting closer as she said my name.

"Oh my fucking God, I want to cum inside you so bad, Sarah. Fuck, but I can't. You're my sister. I can't, but I want it so bad. I want to fill you up and have you lick up the rest."

"Fucking do it," she moaned. "I'm on the pill. Fucking cum inside me I want to feel it so badly."

"Fuck, I />
"Fucking cum inside of me Stan, I want it so bad." I could see the lust in her eyes and I couldn't control my aching erection anymore.

I fucked her as hard as a could for another minute and went as deep as her tight fucking pussy would let me and started cumming the hardest I had ever cum in my life.

"Fuck. Fuck Sarah, your pussy is so fucking tight. Jesus." I fucked her for an entire minute as I came inside of her and she came a second time with me.

I laid on top of her as we were both in a post sex-haze. We both knew nothing would ever be the same, and I was scared at how badly I wanted more.
