My fondest sexual experience happened quite a few years ago, when my sister's friend Allison was staying over our place for a few days. She is a true beauty, with curves in all the right places. For a hormone driven young man of twenty, having a beautiful young female like that sleeping, undressing and changing in my own house gave rise to all sorts of erotic imagery and naughty fantasy. As I lay in bed that night, I put my hand down my pants and felt the erection her mere presence had caused. Dirty thoughts flowed through my mind as I could hear her moving about in her room preparing for bed. Oh, to be a fly on her wall as she undressed! While I might have wished it, unfortunately I didn't hear anything erotic going on in her room, and after a few minutes of silence, my tired mind soon fell asleep.
The next morning I had gone out very early for a short hike, up to the top of a nearby hill and back down again, my usual morning routine. When I came home, my sister's car was gone, so I had assumed she and her hot friend had left together. So with the coast clear, and the perverted male idea of checking out the hallowed place where Allison had slept and undressed in just hours before, I made my way to the guest room to sniff around. What I didn't realize at the time is that my sister had run out to the store alone for an hour, leaving our precious guest in her room to sleep in. Having been in that situation before myself, I suppose lying in bed in someone else's houses while nobody else was home proved to be too erotic an opportunity for Allison to pass up, so she had undressed herself and had begun masturbating in bed. As one may guess, this proved to be my lucky day.
I lightly pushed open the door, not expecting to see her in the room, but there she was, totally naked on her bed masturbating. One can imagine the surprise, shock and exhilaration that instantly pounced on me as I realized the rare goldmine I had just lucked into. Coming in to merely sniff around, I was getting so much more! Allison was laying on her back on top of the covers, not a stitch of clothing to be found anywhere on her beautiful body, with her hand down between her legs, busily working away. Nice ample breasts, slightly falling to each side as she lay there, with perfect sized areolas that complimented two very nicely erected nipples. I espied that the left nipple was noticeably wet: she had been toying with it. A quick glance downward discovered her to be completely shaven, what a naughty image that was. With one leg laying straight on the bed, and her other leg spread apart with her knee bent, it gave me the perfect view of her shaven wonders. Her four fingers were all firmly pressed together while the two middle ones slowly went in circles at the top of her smoothly shaven slit, a most bewitching sight.
When I had first seen her, her face was looking blankly up at the ceiling, off in some erotic fantasy as she touched herself, and I had a short few seconds to glance between her legs at her wonderfully straight labia, before I realized she had discovered me. As our eyes locked on each other, the look on her face was one of placid enjoyment, and seeing me at the door spying on her didn't replace it with any type of embarrassment or outrage. A quick look down between her legs showed her four fingers still going about in that even circle: she was continuing to masturbate, even though she knew I was watching! Seeing her masturbating herself was heaven; knowing she was continuing to finger herself while I watched just blew me away.
Like a hunter who doesn't dare to move or make a sound for fear of scaring the prey away, I stood silent and motionless at her door, hoping not to disrupt the delicate situation before me. She continued to slowly rub her mound, as that same placid look on her face stared back at me. My heart was beating very fast now, I had never had the opportunity to see a girl do this to herself before, so this was a dream come true. The uniquely female motion she used on herself had my eyes bugging out of my head, and I'm sure she could tell by the look on my face the effect she was having on me. One or two heavy breaths came from her as she continued her intimate dance with her clitoris, until she finally broke the silence, "You're supposed to knock before you open the door."
It was said in a non threatening way, in fact it almost seemed labored on her part to get the words out, so heavily was she into what she was doing. I responded, "Well I would apologize and say I'm sorry, but I doubt you would believe me."
She smiled and laughed slightly at my response as she continued to rub herself, beginning to get a little quicker in her hand motions. It was clear her excitement was heightening, not only were her fingers moving in quicker circles, but her body was beginning to squirm about a bit too. She continued to look back at me, but now that placid glassy look on her face had a bit more tension and urgency in it. Seeing her fingers rubbing her clit, and seeing her moist pussy and beautiful breasts were amazing enough to me, but watching that expression on her face was just as incredible. I had seen her many times before, in all types of moods, be it happy, excited, surprised, bored or annoyed. But seeing her masturbation face was simply fantastic to behold. Seeing the way I stared at her little show, in disjointed words she broke the silence, "Have you ever seen a female play with herself before?"
I shook my head no. Her eyebrows lifted in excitement over this answer, "No? Ooh, your heart must be pounding seeing this then!"
