I've often heard people talk about their "sexual awakening"; the thing they experienced when they were younger that first "excited" them, and ultimately would determine their sexual kink later in life.
When I was younger, let's say sixteen, I watched a movie I found in my dad's VHS collection(I was born in 1979) called Animal House. Funny movie for a kid that age, lots of pranks and crazy antics. Anyway, there's a scene in there where a guy spies on a sorority house, and sees a bunch of girls naked. He then notices this one girl he's had a boner for (named Mandy Pepperidge, which I always thought was kind of funny) and, realizing her room is next door, bounces the ladder over to her window.
We then get a nude scene that has taken up permanent residence in my brain, as Mandy slips her dress off, then stands there, sighing and subtly feeling herself up, before finally taking the bra off. It's here where the feeling-herself-up gets more overt, as it becomes apparent she's about to masturbate. I was so disappointed when the scene ends with the guy falling off the side of the house before she starts, but I at least had a good imagination, and knew what to do with the erection she gave me.
In the weeks that followed, I couldn't stop thinking about that scene, and how much it excited me, not just what she was about to do, but the fact that guy was watching her without her knowledge. In short, that scene gave me a voyeur fetish, and I wanted to appease that fetish.
There were plenty of girls in my school that I wouldn't mind seeing naked, but I realized the amount of planning made for way too much work, and my grades were already not great. I then hit upon what I thought at the time was a brilliant plan. My sister, who was two years older than me, tall, blonde, and gorgeous, always went to bed after our parents, leaving only me up and about, and drastically reducing the odds of getting caught.
That first night, my dick was already hard in anticipation, when my sister announced she was going to bed. As soon as she was out of the room, like a ninja, I followed behind her, until she entered her room, closing the door behind her. As silently as possible, I cracked it open slightly, just in time to see my sister take her shirt off. Seconds later, she removed her bra, followed closely by her panties.
As stimulating as it was, though, taking in my sister's incredibly sexy body, I couldn't help but feel like something was missing. My sister was very deliberate in how she took everything off, not like that scene. As exciting as it was seeing my sister naked, it didn't give me that Mandy Pepperidge feeling.
Twenty-something years later, I'm in my forties, divorced(neither party's fault), with a teenage daughter, about the same age my sister was all those years ago, and some might say she even looks a lot like her. I hadn't thought about the night I peeped on my sister in years, when, while scrolling through Netflix one night, I came across that movie: Animal House. For nostalgia's sake, I watched it, and that scene came up. To my surprise, I had the very same reaction that I did as a kid.
That night, I found myself again thinking about recreating the feeling of that scene in real life, but I realized I had no idea how to do so, especially with the heightened security of the last twenty years. Suddenly, my thoughts turned to my daughter...and I instantly pushed them out. Peeping on my sister was bad enough, but my daughter? I mean, she is definitely an attractive girl, and-No! That's...just sick.
