My Sister Won't Bac Off!!

My hot little 18 year old sister Sara, has been driving me nut's lately. She's a senior in High School and a ball of trouble. Sara broke up with her High School sweetheart a few months ago, apparently he cheated on her and she found out. Now she has been acting like a cat in heat ever since.

She flaunts herself in thongs and see through bras around me all the time now. She constantly teases me with her hot body and doesn't act like the sweet sister I knew just a few months back. Her X boyfriend really did a number on her.

I'm 20 years old and living at home for now. I plan to move out soon and go to a University next year. I'm tall with a pretty big cock and my good looks recently landed me a girlfriend who I really care for. My girlfriends name is Megan and she is hot. Megan has a beautiful smile and the perfect ass, but her tits are small. She loves to suck my dick and fuck doggie style all the time. Megan's small tits don't bother me but my Sister Sara sure gives me a hard time about it.

My nerdy Father earns a good living in the computer field and works long hours. We have a nice big house and live a good life. My Mother is always busy with her friends and hanging out at the tennis club. So most of the time in the late afternoon, the house is empty except for my sister and me. Even at night we have a lot of privacy and my parents don't bother us much. Our parents room is on the opposite side of the house and It's just me and sis on the other side.

My sister hates it when my girlfriend Megan is over, she acts like a little brat. It's gotten so bad lately with my sister's antics, Megan doesn't come by as much as she use to. So now when I'm studying my sister comes in and sexually teases me with her sexy bikini's and Victoria Secret thongs and brassieres. We have a nice pool and sauna in the backyard and I have a perfect view from my bedroom window. Now for the past few days my sister has been laying out topless. It's hard not to take a peek at her. Her sexy oiled up body is hard to ignore.

Sara has blossomed into a well busted young sexy woman. Her D size boobs are pushing my buttons and she knows it. She comes in my room all the time while she's laying out and asks me if I want to join her. She barely covers her breasts with her hand and begs me to come outside while she flaunts her sexy body at me. I don't think she really knows how strongly she is pushing my buttons. My sister has THE hottest body I've seen, way hotter than Megan's. She's also a lot more beautiful than Megan. If my sister keeps this up, I just might let go of my morals and fuck her senseless.

My sister came in a few days ago wearing a skin tight sexy blue thong and bikini top. In her hand was some suntan oil and on her face was a big sexy smile.

"Big brother, can you come outside and put oil on my back?"

"Sara, I don't think that's a good idea."

"Awe come on, don't be a such a dork. If you do I promise not to bother you and Megan next time she comes over."

"I'm kinda busy Sara, maybe another time."

"OMG don't be such a pussy Tommy, I won't bite. PLEASE?"

"Ok, If you will back off, I will this one time."

"Yes, thank you brother."

I followed her outside and watched her ass sway back and forth for me. She sat down on the recliner laid and on her stomach. Then she untied her top and let it fall to her sides. She was making me a little nervous. I started on her shoulders and worked my way down her bare back. I hate to admit it but I was getting way more aroused than I thought I would. I finished her back and went past her ass and started on her legs.

"What's wrong Tommy, you don't want to take care of my buns?'

"I don't think that's a good idea."

"OMG, you are so weird. Just rub some on, I can't get back there and if you don't my tan will be uneven. You don't want your baby sister to look funny back there do you?"

"Fine Sara, please don't' tell anyone, especially Megan, she is already annoyed with you."

"Ok I won't, just do it."

I took a deep breath and began to rub oil on my sister's hot little sexy ass. She spread her legs and gave me a nice view of her camel toe. The thong was barely covering her ass crack which made my cock start to grow. I finished her ass and worked my way down her legs. Soon I was done, but she wasn't. She rolled onto her back before I could protest and I got a close up view of her gorgeous tits and big hard juicy nipples.

"Bro can you do my front please?"

"You can do your own front Sis."

"Oh, so you can do my ass but you won't do my chest and front?"

"Come on Sis, I have to get back my homework."

"Am I making you nervous big Brother?"

"Sara, what is wrong with you?"

"Oh, don't be a chicken it will just take a second and you can go do your homework. PLEASE?"

"Ok, fine."

She gave me a big sexy smile and laid back. I began to rub on her shoulders and above her breasts. Then I quickly rubbed oil on her tits and she grabbed my hand and slowed me down. Her nipples were hard and felt real good. I did as she pleased and rubbed her breasts like I was doing it for my girlfriend. She breathed deep and smiled. I loved the way her breasts and hard nipples felt under my touch. I was enjoying this way too much.

"That's much better Tom."

My cock was completely rock hard now. She had me loosing control of myself. I worked my way down past her camel toe and feasted my eyes on her slit. It was cute and very sexy. I did her thighs and lightly touched her camel toe as I did her legs. When I was doing her knees, she began to rub her camel toe with her index finger. I was almost shaking with lust for my horny little sister now. I finished her ankles and feet and watched her boobs jiggle around as she rubbed her vagina inches from my face.

"Ok sis, enjoy the sun, I've got to get back to my studies." I said with a lump in my throat and in my shorts.

"Do you really have to go, can't you bring your books out here and sit with me?"

"Maybe later, I can't right now."

"Thank you for rubbing my boobs and ass, it felt nice."

"Sis, come on don't talk like that... I got to go."

I went inside and back to my room. I was a horny mess, I had to unload before I could study. My hands still had a lot of oil on them so I dropped my shorts and began to stroke my big hard cock, with the same oil I rubbed on my sisters hot body. I peeked out my window and watched my sister laying there practically nude only 20 feet away. She wasn't massaging her camel toe anymore, she just laid there with a big smile on her face. In no time I was pretty worked up and began to shoot cum all over. My free hand slipped and banged the window. My sister looked over at my window and got up. She walked towards the house in quick strides. I was busted. Before I knew it, she was standing in my doorway and I was trying to pull up my shorts up with cum all over my hands and desk.

I looked over at my sister who had a wicked grin on her face. She was standing there topless and looked hot as ever.

"Tommy, you made a big mess. Were you checking me out while you jacked off?"

"Sis, I'm sorry, you just looked so hot and I couldn't study with a hard on."

"OMG, you were jacking off to me. You are in so much trouble if I tell Daddy."

"Sara, you wouldn't?"

"I will unless you do as I ask!"

She walked over to my desk and picked up a little glob of cum with her finger and licked it. She began to rub her pussy and smiled at me. Then she dipped her finger in my cum again and slid it into her pussy.

"Big Brother, you are going to make me cum, like I did for you!"

"What? What are you doing, are you trying to get yourself pregnant?"

She laid down on my bed and rubbed her tits.

"Don't worry I'm on the pill. Eat me out, now!" She protested with a wicked grin.

"But Sis, I can't do that. It would be so wrong, you can't be serious."

"Oh but you can jack off while watching me?"

"I'm sorry about that. You got me very worked up and you look so hot!"

"Well if I'm so Hot, you can eat me out and make me cum, now do it!"

I reluctantly and nervously approached my horny sister. She looked way too sexy to ignore. I got down at her feet and kissed my way up to her thong. She was wet, I could feel her wetness and it smelled very sexy. I lost my self control and went for it. I was way to horny and went at her like she was my girlfriend. She was enjoying the thrill and she began to breath louder and made sexy little noises.

I slid my finger up and down her slit and she began to push her thong down for me. I grabbed the sides and removed her thong and inches from my face was my sexy little sisters pussy. It was hairless and practically had no smell, very sexy and mild. My desire for my sister swelled and I began to eat her out with care and love. I warmed her up nice and was so glad she blackmailed me into doing this. I wouldn't of had the nerve to do it otherwise. I slid a finger into my sisters tight pussy. I massaged her inner g-spot and gently teased her clit with my tongue. I began to put more pressure on both g-spots and soon she was soaking wet. I kept at this for about 10 minutes and she began to orgasm like crazy.

I wasn't done with my Sister yet. I was getting really turned on by our naughtiness and kept eating her out through 2 or 3 more orgasms. I ate her out for about 20 minutes of bliss. Her taste turned me on even more. I was enjoying this way too much then she stopped me, she was getting too sensitive down there.

I dropped my shorts and slid up to her again. I tweaked her nipples and went to kiss her. She welcomed me with an open mouth and our tongues began to dance together. I grinded my cock against her wet pussy and she spread her legs wide open for me. She reached down and took hold of my cock and guided it to her entrance.

"My god Tommy, this thing is huge, I've only had sex with one guy before and I always wanted to have sex with you. I'm glad you're not my first, this thing would of hurt like hell my first time."

I felt her opening and she guided me in. I pushed gently and got my cockhead inside her. She let out a loud moan and her legs shook. I watched my cock slowly slide into my little sisters bald tight pussy. I pulled back out after getting 1/2 way in and pushed in deeper. Her pussy was flowing like crazy as I continued to penetrate her sexy body. She was shaking and moaning and pushing back to meet my thrusts. Her vagina grip felt amazing and her sexy noises were making it hard to hold my load.

Soon we began to indulge ourselves with our wild desires, I was pounding her hard and stretching her tight little pussy to the max. She began to climax over and over as we continued to ravish each others bodies. I wasn't fucking her, I was making passionate love to her. The sexual tension led us to this insane lust and we carried on for a good 20 minutes. I screwed her like she was my lover and gave her the best orgasms I possibly could. Using all the sexual skills I had learned over the years. I was about to explode any minute now.

"Oh god Sis, I'm going to cum soon."

"I want to feel your cum inside me Tommy."

I lifted her legs up off the bed and slammed her as hard as I could. Our bodies were making a slapping sound as we pounded into each other. Sara was coming like crazy and made the sexiest noises. Right before I came I dropped Sara's legs and grabbed my slick cock. I pulled out just in time to deposit my load on her stomach. I shot rope after rope of cum on her chest and tits. She had the sexiest look on her face as we brought each other to a major climax.

She dipped her fingers into the pool of cum on her belly and licked them off. Then she stuck her fingers in it again and shoved my cum into my mouth. I was so lost in lust, I sucked my cum off her fingers.

"OMG Tommy, that was naughty. Did you like fucking your little sister?"

"Sara, I really didn't fuck you... I was making love to you."

I slid up to her and we kissed and grinded each other for a while. We held each other close and played around in our sticky mess.

"Did you cum little sis?"

"I came like crazy, I never came from intercourse before. You were amazing bro!"

"Oh Sara, that was so nasty and wild, I never came that hard in my life. You never came from intercourse before?"

"No, it was never like that with Tony, he never ate me out. He wasn't a very good lover, he never lasted for more than a minute or two, during intercourse."

"I enjoyed that way too much, I can't believe how hot that was Sara."

"Well now we better get cleaned up."

We took a hot shower together and continued our incest. We soaped up each other and I washed her sweet pussy and ass. After I finished her she washed me and paid special attention to my cock and balls. She and I began our wild sexual adventures.

We managed to cool things off at dinner with my parents. We all had our usual talk about this an that. As we were almost finished Sara began to rub my cock under the dinner table with her foot. I tried to play it off and my parents had no idea what was going on. We finished dinner and I went to my room.

Megan called me that evening and I blew her off a bit. I didn't want her coming over the next afternoon, I wanted to see what my sister was going to do next.

After I got off the phone, Sara came into my room without asking. She was wearing one of her sexy Victoria Secrets bra and panties. She came in and sat on my lap and we began to make out again.

"Sara, we can't do this right now, mom or dad could walk in any second."

"Oh, you're no fun."

"Sara, we have to cool it a little ok?'

"Fine." She said and stormed off to her room.

She was out of control, I was a little scared of what she might do next. I went into her room a few minutes after she left and begged her to play it cool around mom and dad. She reluctantly agreed and I went back to my room. I watched some TV for a while and decided to go to sleep around 10:30.

I woke up in the middle of the night only to find Sara naked in bed with me. She was spooning me and although I thought it was sweet, I was getting concerned about her behavior. I turned to face her and she turned around and I spooned her and pulled her in close. I got a hard-on and soon I was sliding my cock into her from behind. I held her big boobs and we began to make love again. Her big breasts and pussy felt so good, I couldn't control myself anymore. We soon built up a nice rhythm and in no time were coming together. This time I unloaded everything I had into her tight pussy. I felt her go through a few orgasms before her pussy got me off. I held her there close for the rest of the night with our sticky cum all over us.

When I woke up she was still in my arms. She looked so sweet and innocent. I brushed the hair out of her face and she woke up.

"Sara honey, you better get out of here before mom comes to check on us."

"Ok Tommy."

She slowly got out of the bed and picked up her sexy bra and panties. She put them on, gave me a kiss on the forehead and left. I was a little paranoid about her boldness. If we get caught, my dad would kill us.

That day went on like normal but I was constantly thinking about my sister. I was worried that this was getting way out of control and that I must put a stop to this before we got caught. That afternoon when I arrived at home I saw Sara's car out front and her hot friend Lynn's car there also.

I went to my room and heard laughing and splashing out by the pool. I looked out to see Sara and her friend topless splashing each other. Her friend Lynn was a hot little Asian girl who also just turned 18. Lynn had always been flirty with me and I would love to bone her as well. She was petite, had a very sexy eyes and a beautiful smile. Her breasts were small but nice and she had the cutest little tight ass.

I watched them for a few minutes and began to get a hard-on from watching them play around the pool. I looked over at my desk and saw a note was left there. I read the simple note.

'Hi Tom, will you come out and play with me and Lynn. She has the hot's for you, and so do I.'

I couldn't believe what I just read, I thought she was most likely teasing me. I changed into some shorts and went to the pool to see what was up.

"Hi Tommy. My sister said with a wicked grin.

"Hi Tommy." Lynn said as they covered their boobs up slowly.

"Hi Lynn, hi Sara. What are you girls doing out here, sounds like a party."

"Were waiting for you to rub suntan oil on us." Sara said with a big smile.

I looked at Lynn who smiled at me and they both got out of the pool and came up to me holding a hand over their boobs. Sara was wearing a black thong and Lynn was wearing a sexy yellow bikini bottom.

"Please Tom, will you?" Begged Lynn.

"Uh sure, I guess so. Who should I do first?"

"Lynn silly, she's our guest." Sara explained.

"Ok Lynn, you're first."

Sara took Lynn by the hand and led her to the towel on the recliner. Lynn laid down on her stomach and stretched her arms out. Sara handed me the suntan oil and I began to rub it into Lynn's shoulder's. Sara sat across from me on the other side of the recliner and helped me rub the oil into Lynn's flesh. When I got closer to Lynn's ass Sara hiked up Lynn's bikini bottom making it like a thong.

Without hesitation I began to oil up Lynn's sexy little ass. Sara spread Lynn's legs and began to rub her pussy lips through the material. My cock was straining inside my shorts and was enjoying this erotic moment way too much. Lynn began to make some cute sexy noises as we massaged her ass and pussy. I moved down her ass and began to oil up her legs.

Sara moved her finger under Lynn's bikini bottom and pulled it to the side, exposed her pussy lips for us. Sara fingered her friends pussy as I finished her legs. I was completely focused on my sisters fingers playing with her friend's pussy.

"OK Lynn, turn over now so we can do your front."

Lynn nervously turned over and her face was glowing.

"Just relax Lynn and close your eyes."

Lynn did as she was asked, closed her eyes and took a deep breath. I squirted a lot of oil on Lynn's chest and worked her shoulders while Sara massaged her breasts and nipples. When I got above Lynn's tits, Sara moved her hand away and let me finish her boobs. I massaged Lynn's boobs for several minutes and got her nipples nice and hard. Sara began to rub Lynn's bikini covered camel toe. This was getting very hot very fast. I worked my way down Lynn's stomach to her bikini bottoms and took a deep breath. Sara spread Lynn's legs for me and I began to rub the fabric covering her pussy crack. I was having the time of my life and enjoying this erotic moment way to much.

Sara pulled Lynn's yellow bikini bottoms to the side giving me a nice view of her snatch. I began to slide my finger up and down her exposed pussy. Then I began to penetrate her with my finger. Sara put her face in her friends crack and began to lick her clit. Soon Lynn was shaking and breathing very fast. After a few more minutes of this attention Lynn had a powerful orgasm. She made my fingers nice and wet with her cum. I licked my fingers to get a taste Lynn's cum. It was a little more spicy than Sara's but still delicious. I finished Lynn's legs as Sara put Lynn's bikini back in place.

"Ok now it's my turn." Said Sara eagerly.

Lynn sat up blushing and Sara kissed her. Then I kissed Lynn and then we all kissed, three tongues kissing together. It was like nothing I ever experienced before. We were all very turned on and ready for more sexual experimentation.

We all stood up together, then we hugged and kissed more. Sara laid down on her back and Lynn and I began our decent on Sara's body. I applied some oil to Sara's chest and began to massage her boobs. Lynn also began to massage Sara's breasts and we were all really getting into this. We worked on her tits for a few minutes and Sara was making some sexy sounds.
