Obsession

Note : This story is completely fictional!

I had always had an obsession with my sister's pussy. When I was 18 years old, I walked in on her fingering herself in the living room. We were home alone at the time, and even though she screamed and quickly covered up, I remember every second of it. I couldn't stop staring at her. I noticed her beautifully even pussy lips, her throbbing clit, and her moaning. Ever since then, I would try to peek at it. When she got out of the shower, looking through the keyhole when she masturbated in her room, you name it, I did it.

I began to develop a lust for the rest of her body. Her breasts are perfect 38 c's, her ass is full and round. And she is TAN. That really gets me going. She'll tan in our backyard, naked, when she thinks no one can see her. But I could.

I started to think that there was something wrong with me. Until one day, I was taking a shower and kind of absent-mindedly stroking my soaped-up dick, when she walked in on me. It must have been on purpose. She opened the curtain and I saw her eyes shoot down to my 8 inches. I didn't try to cover up or anything. I turned around and said calmly,

"Hey, Sarah." She didn't reply, but took one last glance at my cock and walked out the door. I was 19 at the time, and she was 21. It was at that point I realized that we may share the same facination with each other.

Then it happened. It was summer, and she was staying for a week at home on a surprise visit. Lately, I hadn't been able to see Sarah naked at all because of her absence. I was incredibly horny each time I layed eyes on her perfectly curved body. My parents had already planned to go away for a weekend, and Sarah and I would have to keep eachother company. 

I waved goodbye to our parents with Sarah on the front porch. After they were out of eyesight, I looked at Sarah. Our gazes met and she gave me this incredibly enchanting smile. 

As I led the way into the house, I casually said, "A whole weekend to ourselves."

"Yeah..." she replied. "I'm going to go and take a bath, okay?" As she said this, she bent down to take off her socks. I'm telling you, she didn't even try to bend her knees. You could see the outline of her perfect ass through her tight shorts. I could feel my dick start to harden. She got up, and began to go upstairs. As she went, she took off her shirt to reveal her black lace bra. Her back was to me, but I eagerly hoped it was an invitation.

After a brief pause, I headed upstairs. Her clothes were laying on the floor in a trail leading to the bathroom... the one with the biggest bath. Her black silk panties were just outside the door. I picked them up and noticed how moist they were. I held them up to my nose and inhaled deeply. It was heaven.

Normally, Sarah was very worried about intruders and keep the door to the bathroom locked at all times when she was in there. Today, I was able to open the door easily to see my sister, sitting sexily on the edge of the bathtub. She looked at me. My dick was fully up now, clearly visible through my sweatpants. She got up and walked over to me. 

"Sarah, I-" I began. But she pressed her warm body up against mine and put her fingers on my lips. She rested her free hand on my cock.

"Now that can't be comfortable." She said. And it wasn't. My dick was cramped in the sweatpants.

Stuttering slightly, realizing this was my dream come true, I said, "Maybe... maybe we should fix that."

"Of course!" Looking down, she slipped her hands inside my pants and slowly pulled them down. As she went, her entire body went down, too. Soon, my dick popped out, reavealing my 8 inches swaying slightly. "You've grown." She said as she stood up. She urged me silently to take off my shirt, and I obliged. Her hands, now perched on my shoulder, slid down my bare, hairless chest and began took a firm grip on my shaft. 

I leaned in to kiss her. Our lips met and we kissed deeply and passionately. We kissed with growing intensity for two minutes. She broke away and walked over to the tub. She slowly sank into the steamy water. And sat at the bottom. I followed her. At first, we were facing eachother, but we soon shifted positins so that he legs were wrapped around my hips. I could feel her pussy lips on my stomach. My dick bucked just a little. We kissed again and again.

We broke apart a little and she asked if I could wash her. I told her I would if she would wash me. I got the soap from the ledge and began to lather. I went right for her tits. My hands gripped the two melons and I began to knead them. Rotating them while pressing in. God they were the perfect firmness. And they were so lucious. She began to moan and giggle softly as my lubed hands carressed her beautiful breasts. I paused, rinsed them off with water, and engulfed her right nipple with my mouth.

I sucked on it, swirling my tounge around slowly at first, but then faster. My hand slid down her wet body, and down to her wide-open pussy. Still sucking and swirling my tounge on her nipple, I began to slide my fingers in and out of her pussy. The intensity built. 

"OH GOD, YES!" She began to scream with pleasure. "MATT WHERE DID YOU LEARN THIS! OH GOD YES!" She screamed until my fingers and tounge were going as fast as they could, and then she climaxed, moaning in intense pleasure. "Oh, Matt, that was amazing!" She said after she recovered. The water was a little cloudy with her cum. She began to climb up on top of me. I layed back, my head resting on the back of the tub. The was on top of me and her tits were pressed firmly on my chest and I could feel my shaft on the outer regions of her pussy. "And now, as promised..."

She slid down my body and I could feel her beasts go on every inch of me. She kissed my head on the way down and began to lube up her hand with conditioner. She then put her closed fist on the top om my cock and began to slowly slide down and began to give me the greates handjob of my life. About 10 times up and down on my shaft and another 10 were slow. I began to moan as she would occasionally put the head of my cock in her mouth. 

The intensity grew and grew. I started to have the feeling that I was going to explode.
"Sarah...I'm...gonna...cum!" Right as I said it, I exploded. She lovingly let the huge load colect on her face. I watched in amazement. I was living my dream! I squeezed every drop of sticky cum out.

We finished our bath by sitting and kissing and touching eachother. When the water started to get cold, we got out and began to dry eachother off. 

"Maybe we should go to my room, you know, where its more comfortable." I suggested. She smiled at me and agreed. She lead the way and I watched her ass as she walked. When we got back, she stretched out on my bed. I got on top of her, doggie style, and gave her a long, hard kiss. She shifted out from under me and soon she was staddling me just above my still rock-hard dick. 

It was then that she noticed the lube on my nightstand. Tits swaying with her every movement, she leaned over and grabbed it.

"Matt do me a favor and rub this all over my pussy and your chest, okay?"

"Sure." I eagerly replied. She raised herself up so that she was hovering over me. She handed me the bottle and I squirted some into my hand. I used my whole hand- not just my fingers- to rub it all over her pussy. She moaned softly and my hand cupped her pussy lips and slid around to the back. I rubbed some on her round ass only pausing to finger her asshole slightly.

"Why don't you do me, Sarah?" She gently took the bottle from my hands, sat down just above my dick again. This time, it was slippery and my dick bucked just a little again. She squirted the lube into her hand and began to massage my stomach and chest with it. It didn't take too long. She soon mounted my six pack and began to slide up and down on me. I could feel her lips dragging on my stomach. Instinctively, I grabbed her breasts. 

I wish I caught that on tape! We were rocking back and forth so much. She was moaning, I was just happy to finally be touching my sister and my balls were slapping against myself again and again and again. 

As she neared climax, she started to confess to me. "Matt, I've wanted you inside of me... for... so long... OH! I... Want ... you... in ... me! I... want to... ride... your dick... so hard! OHH! She had an orgasm as I gripped her swaying breasts tighter. I found ou then, that my sister was a squirter. Her cum squirted all over my chest. It was so hot, even I let out some moans. 

She was exausted, I could tell, but she lay down beside me and I calmly stroked her pussy. After a minute or two of just lying with our arm aroun eachother, she propped herself up on her arm and with her free hand, took her own cum and began to spread it all over my quivering dick. Slowly, she got up, hovered over my trobbing cock, and slid down on it slowly until she could feel my pubes on her. She then began to ride me like a horse.

Her pussy was so tight inside. I could feel my cock exploring her every inch. Her ass and pussy were lubed to the max. Up and down and up and down. I was moaning in intense pleasure. 

"You are the BEST I've ever had!" She screamed in pleasure. "OH MY GOD...YES.. OH!" She was sceaming and I was moaning. She was sliding up and down and up and down and then...

We both cummed at the exact same time. Her juices were squirting out against me as I spurted into her. We were both letting out loud moans... And then she went back down to my pubes, SLOWLY got off and laid down beside me. We both were exausted. We both fell asleep in eacothers arms, my hand resting on her heaving tits.

The rest of the weekend went by quite similarly. We never got dressed, just walked around the house completely naked. Having passionate sex in every room. It was truly the best love making either of us had ever had. And after our parents came home, we would always try to schedule her "surprise" visits whenever mom and dad spent their weekends away, doing, probably, the same thing.
