"He's doing it again." It was the first thought that came to my mind as I peeked inside my son's room.

Inside the room, my son Kanan was laying spread eagle on his big double bed. I observed my handsome son as he slowly stripped off his clothes. He removed his t-shirt, then his shorts tossing them carelessly on one side. Then he propped his head on the pillows and stared at the screen of his laptop on his side that showed a porn movie in progress.

I had seen him before in that state. In fact, for the last one week, I had been spying on my son...watching him discreetly while he masturbated.

It began a couple of nights ago. I'm an early sleeper, but that night, I was finding it hard to sleep. I decided to take a walk in the backyard. So I left my bedroom, went to the kitchen, opened the door at the back. It opened in the backyard. I pushed the doors noiselessly and slipped outside.

It was a moonlit night. I took a deep breath and began to walk in my backyard garden moving to and fro from one side of the fence to the other side of fence. I was lost in my thought and didn't notice the lights in my son's bedroom. Only when I decided to return to my room I saw the lights.

We live in a double storied house at the outskirts of the city. We are only three in our family my husband Dave, my son Kanan and me. Our bedrooms, Kanan's as well as mine, both are at the ground floor and first floor rooms are used only for the guests. There is a common wall between out bedrooms, and a door that opened in Kanan's room. However, we kept that door permanently locked so that he, and we too, could enjoy our privacies.

I didn't know why I wanted to look inside his room. Probably I was just curious.

I looked for an opening through the windows. After a little snooping around, I was able to find an opening through the drapes on one of the windows. Carefully, I positioned my eyes at the opening and peeked inside my son's room.

I watched something that I shouldn't have watched.

My son was laying on his bed...completely naked...not even a single stitch of cloth on his lean athletic body. His eyes were glued to the screen of his laptop that showed a group of men and women displaying all sorts of screwing skills. Unaware of my presence at the window, his hand was busy massaging his rigid cock.

Something at the back of my mind screamed, warned me to move away from the window immediately. However, my eyes were drawn to his rigid tool. I could not take off my eyes away from his boner. My feet refused to move.

I remained there and watched my son as he whacked his cock. I witnessed every moment of my son's solitude...the furious pistoning of his fingers over his massive dick...the contortion of his handsome face as his orgasm hit him and the violent release of incessant jets of hot frothy cum.

I observed everything.

I must admit that I was awestruck from what I had witnessed. When I returned to my room, I was extremely horny. I stripped and lay on my bed. My fingers reached between my legs and I played with my pussy. I finger-fucked my hungry pussy feverishly until my whole body erupted in a shattering orgasm. Although, I tried not to think about Kanan while fingering my wet pussy; the image of his gigantic dick kept coming into my imagination again and again.

I had a mind blowing orgasm that night.

That moment, I didn't know that it would change my life forever.

Next morning, I was remorseful, ashamed of my wanton behavior. I didn't know what had come over me last night. I had never done anything like this except in my fantasies. I was married relatively young, and so far my life had been of a simple stay at home mom's life, bearing and bringing up our only child, keeping house, being faithful to my husband. I had been a straight, upright housewife...a mother who dressed rather conservatively and a religious woman who visited church regularly.

I cursed myself for being so stupid. I had committed a serious crime by spying on my son...a forbidden sin.

Throughout the day, I struggled to put his thoughts out of my mind. I resisted the wanton temptations to think about the firmness of his thighs, his bushy crotch and the magnificent piece of flesh rising so proudly between them.

By the evening, I was in control of my lewd emotions. I resolved that it was a freak accident and it wouldn't happen again.

However, as the night progressed and I retired to my bedroom, my resolution began to melt. My heart longed to see that scene again. My pussy began to cream and I wanted to watch my teenage son beating his cock. I tried to sleep but I couldn't. I tossed and turned in the bed but to no avail.

Finally, I surrendered to my lust and left my bed. My feet dragged me to the backyard...to the same place where I was last night.

Hiding behind the window, I watched my son masturbating for the second time. His beautiful throbbing cock...jets of his hot cum flying out off his peehole. I was driven wild with lust. I was extremely horny when I returned to my room. I again fingered myself to a terrific orgasm.

After the second night, I lost my inhibitions. My horniness took complete control of my thoughts and I did what it wanted me to do.

I was again there on the next night and every night after that. Each day, unaware of my snooping eyes, my son whacked his cock and left me lusting for.

Every time, it was followed by a furious round of self gratification in my room.

This night was no exception. I was standing outside my son's room, peeking through the opening...excitedly watching my son stripping. It was a cold November night. I felt a mild shiver standing at the window. I was wearing only my white panties underneath my gown...no bra.

Kanan had turned eighteen last December. As his mother, I had the opportunity to watch him grow into a fine handsome young man. It was rather unbelievable that my small kid had suddenly become a man.

He was a good son, good in studies and a very good athlete I was really proud of him.

I was aware that he was dating one of his classmates Linda. But I was not sure if he was screwing her too. He appeared so innocent.

My sex life with my husband wasn't going very smoothly. In fact, I couldn't recall when Dave screwed me for the last time. It seemed like ages. Dave was too busy with his work. After twenty odd years of our evidently successful marriage, he didn't have enough time for his wife and his son.

I won't say that he wasn't a good father. He was and he was good in bed too. But lately he seemed to have forgotten about one of his major duties. He was no more interested in sex. He was completely oblivious of my physical needs.

I had resigned to my fate; settled in my life as a homemaker and a doting mother.

However, watching my son masturbating on that fateful night ignited a hidden desire in me. I realized how much I was missing sex. I recalled the nights when I lay in my bed wishing Dave to be between my spread legs with his monster cock reaming through my wet pussy...just like it used to be during the initial years of our marriage.

Now everything seems to be vanished. Dave was my first love. He was the man who took my virginity and so far he was the only man who had the rights to fuck me any time he wanted. I still loved him. All I expected him to be more considerate about his wife's needs.

Inside the room, Kanan moved on bed. I woke from my reverie.

Kanan was completely naked now. His hand was now gripping his hardened cock. He began to stroke it gently. He continued to stroke his cock until it was hard and erect. His eyes were glued to his laptop screen that showed a man and a woman busy in their furious love making.

I amorously observed my handsome son. He looked gorgeous, more like Dave when I first met him. He looked an exact replica, same handsome face, a young athletic body, thick dark hair and a heart warming smile. No doubt my son was very popular among the girls. Like his father he was also endowed with a magnificent tool, long, thick and with a beautifully swollen mushroom shaped head.

A warm feeling rushed up and down through my body. I could feel my horny pussy began to melt. My legs grew weak as I watch my son playing with his mammoth hard on.

Intuitively, my hands reached between my legs and I rubbed my pussy through the gown.

His cock beating got furious with every passing second. His eyes were still staring at the laptop screen but I doubted if he was actually watching the movie.

My legs trembled and a strange shiver began to run through my body. I furiously rubbed my engorged clit. Suddenly, my pussy began to throb. I knew if I didn't stop I would start cumming there itself. I removed my fingers from my pussy and squeezed my legs unsuccessfully trying to stop my orgasm.

It was too late. A loud moan escape from my mouth as my cunt lips throbbed even more violently. My entire body shook with the ultimate pleasure the moment my orgasm hit me. My mind was reeling. I had to take support of the wall to avoid collapsing on the ground. I could feel the warm fluid running down my thighs.

I let my body go and enjoyed the blissful feeling.

Once the tidal waves of pleasure began to subside, my fingers were back to where they were before. My attention was again drawn to my son.

Kanan's handsome face was contorted with rapture. His fist was running over his cock like an automobile piston. The purple mushroomed head of his beautiful cock looked even larger.

Suddenly, his body arched. His mouth opened and he gave a loud cry. I could hear only a muffled cry behind the closed windows. His hand squeezed his cock tightly. The engorged head throbbed and a large drop of cum shot from the tip of his cock. His thick sperm flashed in the air and landed over his chest. Another shot followed; that also landed on his chest. Then another, and another...I stopped counting.

I watched the entire firework.
