This is the first part of what will be at least a two part story. I left the ending hanging which is a little unfair, so I included a sneak preview into the next installment. It doesn't answer all the questions, but hopefully it will make you come back for more. I am always interested in feedback from readers, and particularly any ideas you may have for part 2. Hope you enjoy.
Chapter 1
My sister is almost perfect. Besides being beautiful and sexy with a bubbly personality and friendly smile, she's the head cheerleader at her high school, a star on the girl's track team, and near the top of her class academically. Sometimes it infuriates me because I'm as close to average as one can get. Other times it excites me, which is a problem. After all, I am her brother.
Her name is Diana. She has vibrant blonde hair that hangs past her shoulders. Her eyes are bright blue. She stands 5'6" and weighs 120 pounds with long, powerful legs, and an ass that creates instant erections when she wears tight jeans or skin hugging shorts. Her c-cup breasts ride high on her chest. The dark pink nipples are slightly swollen and point upward. How do I know? I've seen them.
Diana is three years younger than me. She was just beginning to mature from an adolescent into a fully developed teen when I went off to college. Every time I came home for the holidays and summer, I was amazed at how she was developing. It was hard not to find her sexy and attractive, but as her brother it was more admiration than lust, or so I told myself.
Things began to change when I came home for spring break soon after Diana's eighteenth birthday. One afternoon, I saw her coming out of the bathroom with a towel draped around her otherwise naked body. She didn't see me and must not have thought anyone was home because she left her bedroom door ajar. I peeked through the small opening and saw her standing in front of the mirror above her dresser.
Diana let the towel fall to the floor and stood there looking at her naked body. I could only see her from the waist up, but I had a perfect view of her magnificent tits. I watched as she squeezed them and played with her nipples. Then she dropped a hand down where I couldn't see it, but her arm was rapidly moving up and down in a way it could only be one thing. She was rubbing her pussy.
I thought my poor cock was going to rip through my shorts. Diana closed her eyes and bit her lower lip. Moments later, her body shook and trembled. I heard her gasp several times. After taking a deep breath, Diana lifted her right hand to her nose and smelled her fingers then slipped them into her mouth and sucked them clean. After that, she stepped away where I could no longer see her.
I rushed into the bathroom, pushed down my shorts, and wrapped my hand around my rock hard cock. I tried to focus on a girl I had fucked at college rather than my sister, but it was impossible. All I could see was Diana staring up at me and begging me to fuck her hot pussy while she rubbed her perfect tits and hard nipples. In less than two minutes, I splattered the wall and floor with several spurts of cum.
I cleaned the mess, pulled up my shorts, and walked out of the bathroom, almost running over Diana who was just coming out of her room. She was dressed in a pair of skin tight cutoffs with a red top stretched across her perfect tits. I could see little dents poking out made by her erect nipples. Her face was still flush from the orgasm.
"Oh, hey Nick," Diana said, smiling at me with her pearl white teeth. "I thought you were over at Joe's house."
"I was, but he had to go somewhere so I came back. What are you up to?"
"I just finished running and taking a shower. Mom asked me to put the roast in the oven. Then I'm going over to Jenny's house to hang with the girls before my date with Jason tonight."
"Jason? What happened to that guy from Christmas?"
"Carl? We stopped dating a few months ago."
I knew my sister played the field. To my knowledge, she had never had a long term boyfriend, just guys she dated.
"You mean he dumped you?" I teased.
"More like I dumped him. He wanted...well let's just say he wanted more than I wanted to give."
"Are you trying to tell me you're still a virgin?"
"Well, technically, yes. And I'm proud of it. I'm waiting for the right guy. I just haven't met him yet."
"Technically?" I asked with raised eyebrows. "What does that mean."
"None of your business," she said, turning to go downstairs. "I'm not going to talk about my sex life with my brother."
I couldn't get the word "technically" out of my head. What did it mean beyond never having had a penis in her vagina? Did it mean she still had her cherry, or had she fucked herself with a dildo or vibrator? Certainly her fingers had been in her pussy. That I had watched. What about guys she dated? Had they fingered her? Had she given them hand-jobs or blowjobs? Had she made them cum?
Images filled my head of Diana with a big hard cock in her mouth. Then it became my cock. My thoughts were becoming too incestuous. I needed to get my mind off my sister. I tried jerking off to porn but didn't work. When I got close, the porn star in the video became Diana staring up at me begging me to cum all over her face and tits. I went off like fireworks on the Fourth of July..
After Diana left for her date that night, I went into her room and searched through the laundry bin. Near the top I found a pair of used panties. I picked them up and carefully examined them, then held the crotch to my nose, hoping to smell her pussy. Instead, there was a faint odor of urine, but even that excited me. I jerked off all over them and put the panties in the bottom of the bin hoping she wouldn't notice.
The next day I went back to her room when she left to go shopping. I pulled the panties she had worn on her date with Jason out of the laundry bin. These definitely smelled like pussy. I didn't know if it was because she got wet when he kissed her and played with her tits, or if she had let him rub her pussy. It really didn't matter. My head was spinning with lust just smelling the aroma emanating from her panties.
I wrapped the panties around my cock and quickly filled them with so many spurts of my creamy essence that it was dripping onto the floor. What I did next was really perverted. I opened Diana's underwear drawer and used the cum-soaked panties to smear my ejaculate all over the crotch of her panties and cups of her bras.
After that I became a peeping Tom. I spied on Diana every chance I could get, whether it was in the kitchen or while watching TV or just strutting around the house. I stared at her rounded ass through the tight shorts and jeans she wore. I gazed at her tits which bulged from her revealing tops. And, of course, I continued to sniff her panties. I looked for an opportunity to see her naked again, but she was careful.
I finally bought a miniature camera and hid it in her room so I could watch from my computer. That night, after she returned from a date with Jason, I saw her undress for the first time. She had her back to me, but I could see her naked ass when she bent over and peeled down her panties. It was perfectly round with two creamy cheeks divided by a dark cleft down the middle.
Diana stayed bent over so she could pull her panties off her feet. Not only could I see her ass, but her swollen pussy puffed out from between her thighs. The camera had a zoom feature. I moved it closer and stared at the pink folds peeking out from her gash. She finally stood and turned around. Her pussy was shaved bare exposing a cameltoe that hung between her legs like a ripe peach.
My sister walked over to the mirror and stood in front of it admiring herself. I moved the camera to follow her. From this angle near the ceiling, I could see her tits and pussy in the reflection, as well as her ass. Like last time, Diana squeezed her tits and pinched her nipples, then briefly rubbed her pussy, parting the folds with her finger before pushing it up her cunt. She pulled it out and sucked it into her mouth.
My cock was poking up from my lap like a flagpole and leaking pre-cum down the sides. I was afraid to touch it for fear of premature ejaculation before the show ended. After licking her finger clean, Diana pulled a dildo and vibrator from under her mattress. The vibrator was was red with a small bulb on the end of a thin six inch curved stem. The dildo was flesh colored and ribbed in the shape of a penis about eight inches long. It had a suction cup on the end.
