Naughty Jerking

Being in 8th grade my hormones were working on high gear. It didn’t take much for me to retreat to my bedroom to whip out my penis and jerk off. So when a situation literally jumped in my lap one night I rode it for as long as possible. I used to go to bed around 10:00 pm on school nights and would read, finish homework or get right to the meat of the matter...jerk off. The night I’m about to talk about is no different except after shooting my load I had to pee like a racehorse. My sister was using the bathroom upstairs since she just got home from cheering at a wrestling match so I went downstairs to drain the lizard. On the way back up to my room it was dark, all except the light peering from under the bathroom door. What a pity I thought..I’d love to see my sister naked. She was a senior and cute with a Dorthy Hamel haircut and a nice curved body. Once when I was younger I pulled down her tube top to spring out her milky white boobies. That was a source whacking off ever since. She had huge nipples ..the size of billiard balls and so puffy. As I turned into my room I noticed something I never saw before, a light from the crack in the door jam. I put my head up to it and squinted through. Yes I saw movement, my sister moving around the vanity. The crack was not big enough so I snuck into my room across the hall and using a nail file I started very quietly to pry the door jam away from the door frame. I only pried it open a little, but it was enough. My sister was leaning on the vanity picking her face while her hot pale boobs swung over the sink. My heart pounded and my penis throbbed as her arms were up resting on the mirror exposing her arm pits and her sagging heavy teen tits. I remember breathing heavy and wanting to jerk off, but I didn’t. I just watched her being teased I could not see more. As fast as she appeared she was gone again and the shower was turned on. She sat on the toilet and could not see much. Soon she was gone and I heard her get into the shower. I retreated to my room and jerked off a second time. It was a crazy thing. But being a boy I acted the next day, I went straight to work on that door jam. I loosened it up proper so the whole crack could be manipulated with my nail file. A few nights went by without any new developments in my new hobbie, my sister had no late cheerleading engagements. But the night did come. My plan was simple after my sister went into the bathroom I opened my door and kept it open. My penis was out already to avoid any fumbling stuff. The nail file went in and the prying commenced. The light of the bathroom hit my eye and so did my sisters body. She was sitting on the vanity with her face up to the mirror picking zits. But since I prepped the jam ahead of time I could get on my knees and look farther down. I hit the jackpot, her pink pussy was looking right at me. I was amazed how wet it was and pink. She was furry down there but not enough to hide her folds and big pussy lips. My hand worked on my dick fast as I new any second she might move. She adjusted her bottom a few times but that was it, her legs stayed parted and her wet juicy pussy stayed there for me long enough. I wanted to shoot my load but I forgot my hanky or cleanx, damn. So I got up and finished myself off behind my door. This was the first time I saw my sisters pussy, it wouldn’t be the last. Her senior year I watched her often at night in the bathroom. I watched her masturbate on the vanity and on the toilet. Watching her orgasms made me feel bad though and guilty. But I remembered to bring a hanky so I could cum with her.
