I don't think I can remember what triggered it, but I suppose it all began after Mom and Dad had split up just after I began my junior year in college. I was 21 years old. My dad had taken off to another city and Mom had been so devastated that I had moved back home from living on campus. In December, a few months after I moved back into my old room, I was home alone one night while my mom was next door at a Christmas party. I remember having a conversation with Mom while she was getting ready to go out. For some reason I began to take notice of how sexy she looked in her dress. This made me a little bit curious and I got the devious idea that I would spy on her that night. I went poking around the dark and dingy paint room in the basement of our old house when I came across a large broken mirror. The mirror was one of those large wall covering mirrors which had broken in two pieces. It must have been about 5 feet tall and about 3 feet across. I lugged the piece up to my room and placed up against my dresser at a slight angle opposite the side of my bed.
My devious plan was a simple one; I would use the mirror to spy on my Mom's room which was directly across the hall from my own. I positioned the angle of the mirror so that, from my bed, I had a direct view into my mother's bedroom. I turned off my lights and hoped into bed. All I had to do was wait for Mom to come home and the show would begin! I was so excited. The mirror was so big I had a large image of the bedroom. And so I waited and waited...
Finally, after what seemed like an eternity I heard the side door slam. Mom was home! I heard to the stairs creek as she made her way up to the second floor. She poked her head into my room.
"Peter?" she said softly.
Of course I didn't respond as I was fast asleep, as it was after all past 1 in the morning. As I feigned sleep, my heart was pounding with excitement. I was scared she might hear it. Within a moment I heard her step away. That was my cue and I turned over and gazed into the mirror. Now was the moment of truth, and just as I had hoped Mom left her door open. She must have been convinced I was sleeping.
At the time Mom was in her early 40s. She's a fairly attractive, kind of short lady, standing about 5 feet tall. She had smaller tits, maybe about a 34c or so. In my estimation her best feature, though, was her curvaceous figure and nice round ass. She had these beautiful hips, not too fat or anything, just a nice shape. I had never really gotten a real good look at her naked, that I could remember anyways.
By this time my heart was beating in my throat I was so excited. Lying on stomach, I ground my cock into my semi-closed Vaseline greased hand which I held under my abdomen in a cup shape. It was sheer pleasure, but I had to watch that I didn't cum too early!
Anyways, as I watched in the mirror, Mom was as standing in front of her dresser. She had already undone the back of her blue skirt which she gently slipped off and placed on the foot of her bed. Underneath her skirt she was wearing white nylons and although her blouse was now hanging halfway down her hips I could see she was wearing nice white cotton panties. Then she slipped off her nylons which she stuffed into a ball and slipped them into the top drawer of her dresser. To my slight surprise she then turned and walked in my direction out into the hallway. She turned and walked into the bathroom which was located at the end of the hall in between our rooms. As she walked out into the hall I caught a glimpse of a the dark outline of her pussy. Holy Shit I thought..
For what seemed like an eternity, I listened to sound of her peeing in the bathroom. I couldn't see into the bathroom, so I imagined what it must have looked like. Within a few minutes she was out of the bathroom and no sooner did she come into my view when I noticed she no longer wearing her panties but carrying them in her hand. Here long blouse hung down pretty low, but I could now make out the bottom of her ass cheeks. Wow!! My cock stiffened. Slowly she walked to the back of her room and tossed the panties into the dirtily laundry hamper. She then turned and began to walk back in my direction towards her dresser. As she walked she was carefully unbuttoning her blouse from the bottom up. As she did so, her blouse split wider and wider as she undid the buttons, revealing to me a good view of her dark hared pussy. Holy Fuck!, I thought. Within a moment her blouse was off, but my gaze was still fixed on her beautiful pussy. My heart was pounding again in my throat.
In what seemed like a single motion she undid the back of her bra and slipped it off. Mom's tits were firm and she had these lovely pointy red nipples. I was in awe and my hungry eyes feasted on the sights. At this point she was putting her skirt and blouse on a clothes hanger. She then turned to hang them up in the closet, finally giving me a view of her naked ass. Her heart shaped ass was nicer than I had imagined. Just then, the icing on the cake - she dropped the clothes hanger on her way to the closet and as she bent over to pick it up,I got this great view of her pussy from behind. No longer being able to hold back, I erupted with the most awesome orgasm imaginable. I must have oblivious to things at that moment because, little did I know it, but mom had actually heard me and noticed that I had been watching her through mirror.
That night must have been one of the most erotic experiences of my life. Those images in the mirror were forever burned in the back of my mind. I must have masturbated at least 3 or 4 times that night re-living the experience over and over again. Any guilt I may have been feeling was being completely overrun by the sheer erotic pleasure of the whole thing. I was so turned on, I knew absolutely that I had to see some more.
By the next evening, I was really horny with anticipation. My sister was a little surprised when I announced I was tired and that I was "going to bed early" that night. I hopped into bed and I waited, and I waited and I waited. Finally by midnight I heard Mom come up the stairs. I saw her come into the view of my mirror as she stepped into her room. I felt that sinking feeling of excitement. Mom was wearing a cotton button down blouse and a pair of levis. I admired how hot her ass looked in those jeans and I tried to imagine what it would look like naked again. I was getting my chance. With her back still turned she slowly took off the jeans. By this time I was no longer content fucking my hand in awkward positions. I needed some room to maneuver, so turning up on my side, I gently pulled the sheets back liberating my massive erection to the open air. With my cock all greased and lubricated I resumed my stroking as Mom finally pulled her jeans off. Then came the panties, and for a brief moment, I caught a glimpse of her wonderful ass before it was hidden underneath her hanging shirt.
As she had done the night before, mom walked to the back of her room and deposited her jeans into the dirty laundry. Turning around mom slowly walked to front of the room while she unbuttoned her shirt. My eyes were transfixed on sight of her pussy which was clearly in view. By the time she reached the doorway to her bedroom her shirt was completed undone. It was then that I realized that she wasn't wearing a bra. Holy fuck! I thought. This was going to be better than the night before. For some reason the surprise was real turn on and almost subconsciously, I picked up the pace of my stoking. From that point I would always look to see if Mom was wearing bra or not.
Consumed with the pleasure of my excitement it took me a few moments to notice that mom had froze. Looking up at her face, she seemed to look puzzled and within a few moments her eyes widened in recognition. Holy Shit!!! She was looking right at me. Mirror must have been to big or something, cause even though my room was very dark, Mom could still obviously see me. I froze like a deer caught in the headlights of an oncoming car, even holding my breath. It was of no use of course as Mom was able to see me clearly. I had been busted!
To my complete surprise, Mom marched across the hall and into my room like she had been shot out of a cannon. I didn't expect her to walk into my room almost naked like that. I fumbled aimlessly to pull the covers over my exposed cock. It was too late Mom had certainly gotten a good view of me with my greasy erection in my hand. Even if she hadn't I'm sure she had seen everything through the mirror.
I was so embarrassed. All of a sudden my little fantasy world had been brought crashing back to reality, but as once I had gotten over the surprise of the situation I realized that Mom was actually standing in my room naked! I looked up. Mom was standing with her hands on her hips and was clearly blushing a deep red color in her face and neck. Was she embarrassed? Angry? Maybe.. maybe she was even little turned on?
"Peter! What the hell do you think you are doing?" she exclaimed.
"What? Does this turn you on or something?" she said rhetorically as she pulled open her shirt like one of those trench coat flashers.
I couldn't help but gawk at the closer view of her pussy I was getting. Just then she seemed to pause, perhaps to hold herself back from saying something she might regret later. Realizing that she had acted on impulse she seemed to struggle for a moment as to what to do next. I didn't know what to expect as things were beginning to take a turn to the surreal.
Folding sides of her shirt over her exposed body, mom sat down on the bed with her back turned to me facing the mirror.
"So this is where you watch your show" she said as she leaned forward and peered into the mirror.
