My younger sister had friends spending the night just about every weekend. They would come over in the evening, eat dinner with us and after my parents went to bed they would put on their little nighties, watch TV or movies for hours and finally go to bed. One particular girlfriend of my sister's was a little hottie. She was petite, fair skinned with long black hair, and green eyes. Her name was Angela. Every time she spent the night she would put on the same white nightie. It was just long enough to cover her ass; even the slightest movement would cause it to rise just enough for me to get a glimpse. I was positive she did this on purpose.
She would always ask me if I thought she was pretty and I would respond hesitantly, telling her I thought she was. Each and every time she spent the night I found myself masturbating at least four times before I could go to sleep. One night Angela came to sleep over with my sister again but this time I couldn't contain myself. She performed her normal routine, prancing around, seemingly ignorant to my yearning. After my parents had gone to bed, I was lying on the couch watching television. Angela walked into the living room and slowly arched her back, pushing her ass out, and bent over to lay down on the floor which caused her nightie to slide up, exposing her thin white panties and her creamy, white thighs. I felt my cock stiffening and I covered my lap with a pillow to avoid detection.
As Angela lay on the floor with her chin on a pillow I could see right up her nightie. Now my cock was so bloated I couldn't resist secretly tugging and rubbing my tight head beneath the cover of the pillow. I could have easily cum after about three minutes of seeing Angela move around on the floor, trying to make herself comfortable. I had finally had enough, I quickly stood up and walked to my room. I had my shorts around my ankles and my cock in my hand before the door was closed. I stroked my cock imagining entering Angela from behind with her nightie hiked up above her waist and her panties moved over just enough for me to get inside. I came in seconds, moaning aloud at each of the last few strokes. I decided to stay in my room for the rest of the night fearing I would really attempt to make this fantasy reality.
I tried to occupy myself by reading or just thinking of other things but no matter what I did all I could think about was walking out there and thrusting my cock into my sister's friend's pussy. Two hours had gone by and I was sure Angela and my sister had gone to bed. I imagined her lying in bed having removed her nightie to make herself more comfortable. My cock became hard again and my heart began to race. I had decided to sneak into my sister's room and try to get a glimpse of Angela sleeping. After pacing back and forth from one side of my bed room to the other I worked up the nerve to do it. I left my room, walked down the hall and stood at my sister's bedroom door. It was open just a crack and I put my eye up to the door knowing they could hear my heart pounding.
My cock throbbed as I stood there, excited, nervous, and a little guilty. I could see Angela positioned on the bed with the blankets down below her knees, and just as I had hoped, she had removed her nightie, her white panties and her little, firm breasts there for the taking. I took out my cock and began to stroke it in the hall right outside my parents' door. Suddenly, without thinking, I held my breath and as silently as possible I pushed the bedroom door open just wide enough to enter the room. I crept over to Angela. I still had my cock out and continued to stroke it. My heart pounded and I did everything I could to maintain a steady rhythm on my cock without cumming.
I had to stop. I released my cock and stood there for a while just staring at her tight, young, white body. Her hips were shapely and full and her breasts were perfectly tiny. I decided that I could not go back to my room unless I could touch her first. I stood there frozen, unable to act for what seemed like hours. I listened and looked for the slightest hint that Angela or my sister might awaken. Finally I leaned over and touched Angela right on her soft, young mound. I made sure to touch her gently so she wouldn't wake up. I removed my hand, crept out of my sister's room and dashed down the hall, closed my bedroom door as quickly and silently as possible and got into bed in the dark. I began stroking my cock frantically but I made a conscious effort to make it last, not to cum too quickly.
