My dad was killed in an industrial accident just before my little sister was born and I was only six. I remember he was a big man, but being only six, every man was big from my perspective. Being so long ago, the memory of his death and funeral have almost disappeared into the fog of my memory. We moved into my mom’s big family home where Mom had help from my grandmother in those early years, helping to raise me and take care of my baby sister, until her death several years later. The house was big and old, filled with the type of furniture and decorations an old lady liked, with a big private backyard for me to play in, including a tree house. My little sister Amy grew up, and was always underfoot, never leaving my side if she had the opportunity. Mom received a big settlement from the company my dad had worked for, along with a life insurance policy. It was enough money for her to back to school and become a real estate broker. She worked for another broker for several years until she had enough clients to open her own real estate brokerage firm, quickly becoming the number one agent in our town.

As I grew up, it became apparent that I would take after my father in most ways. By age twelve, I was taller and heavier than my 5’2” 110-pound, 29-year-old mother. I had blond hair like her, but my eyes were light blue, whereas hers were light green. Amy was a cute little six-year-old, and it was obvious she would grow up to be a younger version of Mom. It was about this time that I discovered that a cock could be used for more than peeing and I became a chronic masturbator. I jerked off every morning before school, every night before sleep, and several times during the day if I could find a private spot to relieve the pressure in my growing balls. I would imagine one of my pretty classmates or a neighbor lady, but it wasn’t until the summer that I turned fifteen that I started fantasizing about my mother.

It was a hot day. Amy was at a sleepover at a friend’s house, and I had gone to swim in a friend’s pool to cool off, only to find him and his family gone. I returned home, took off my tight swimsuit, and put on my baggy gym shorts, commando as usual. When I passed my mother’s room, I noticed her door was open and she was standing in front of her dressing mirror with a towel wrapped around her head and nothing else. She must have had the water running when I returned home, and didn’t know I was in the house. She stood before the mirror and lifted each of her firm breasts with her hands as if she were weighing them. She pulled on her nipples making them stick out hard. Turning she looked over her shoulder at her heart-shaped ass, checking to see that it was still high and tight.

Standing in the darkened hall, I had a clear view of everything. Her pubic hair was blond like her head, but very thin. The slit of her pussy was just that, a slit. My mother was more beautiful, more sexy than any woman I had ever seen in those dirty books that me and my buddies looked at. I had an instant hard-on, tenting my shorts. I lifted the leg hole with my left hand and wrapped my right hand around my six-inch cock and pulled. It took about thirty seconds for me to blow my load of cum into the hallway floor, but I didn’t stop or go soft. Mom moved the floor mirror over beside her bed and tilted it down. She climbed up on the bed and stacked three pillows on the headboard. She laid down on her back, put the bottoms of her feet together and spread her knees apart, and checked out her pussy in the mirror. I had a full view of everything from just ten feet away. Her pussy slit opened, showing me a very wet pink pussy. I watched as she pulled the little lips open and slid a finger inside as she purred. She slowly fucked herself with first one and then two fingers as her eyes were glued to the mirror. I saw her clit swell up and demand attention. She pulled on it, rubbed it up and down and side to side. She strummed it with all the fingers of her right hand as if strumming a guitar as she continued to purr louder.

I had often heard this sound coming from her bedroom before but had not associated it with her masturbating. I was still jacking off, but this time my well-lubricated cock was coated with my cum and was leaking profusely. I was harder than I could ever remember and my hand could barely reach around it. Mom took her left hand out of her pussy and smeared her juice across her nipples and pulled them skyward, pinching them hard as she did. Her eyes never left the mirror as she watched herself climb toward orgasm. I had moved closer to the open door, still concealed by the dark hall. The light shining in the window flowed over her body, blinding her of my presence. I was about to blow again. Suddenly closing her eyes and thrusting her ass off the bed she howled as she came. Her body was ridged and vibrating. I blew my cum through her open door onto the floor of her bedroom, unable to control myself. For a full minute, she remained lifted in the air with her right hand a blur on her clit, before she suddenly collapsed back on the bed with a sigh. Her eyes were still closed and she had a smile on her lips. I eased down the dark hall, careful where I stepped. I knew that some of the old wood floor would creak if I stepped in the wrong place so I carefully made my way to the back door and into the yard.

I didn’t have any place to go, so I climbed the ladder through the trap door into the treehouse to relax and wait. I had several old blankets up there to lay on, and my stash of nudie books to look at, but after blowing twice in the hallway, my soft dick wasn’t interested in any of the girls in the magazines. I stripped off my tee shirt and baggy gym shorts so the cool breeze beneath the tree could cool my sweaty body. I lay there with my eyes closed, reliving what I had seen. Suddenly I realized I was growing hard again. I reached into the corner for my bottle of baby oil, coated my cock, and slowly stroked up and down as I watched my mother orgasm over and over. I don’t know how long I lay there jerking off again, but eventually, I blew the fourth load of cum for the day onto my chest. One load when I woke up, two in the hall, and now this one, weaker than the others, but just as satisfying. I fell asleep.

I woke up sometime later, hearing my mother call, “Mathew, are you up there? Come inside. Dinner is almost ready.” It was a good thing I woke up before she climbed up the ladder because I was still nude with dried cum on my chest and my spent cock, lying limp and bright red from abuse. At dinner, Amy moved her chair as close to mine as possible. She always called me her boyfriend, and I would run my fingers through her blond hair and call her my little girlfriend. I loved my little sister and knew she would grow up just as beautiful as my mom.

I was a good student, loving math and science, however, I wasn’t the typical geek since I was also good at sports, playing football, wrestling, running track, and lettering in all three sports. I didn’t date often, and never took a steady girlfriend, although I had plenty of opportunities. Girls were always calling the house, or dropping in to see me, but I wasn’t really interested. I compared all females to my mother, and they all came up short. I knew I was in love with my mother, or at least in lust with her. My bedroom was next to hers, and thanks to the old house, there were cracks in the walls and ill-fitting old doors that gave me ample opportunity to see her necked often. I had drilled a small hole in the back of my closet, so I had a clear view of her on her bed at night, and the walls were thin enough to allow me to hear her as she orgasmed. My mother is a very horny woman. She masturbated almost every day, much to my enjoyment. One day, as she was hanging up some of my shirts, she asked me, “Mathew, what is this sticky stuff on the floor of your closet?” I lied about spilling a little coke but made sure to cum in a dirty tee-shirt after that. I started leaving my door cracked open when Amy wasn’t home, hoping Mom would catch me jerking off my big cock, but to my knowledge, she never did.

I graduated from high school with honors but didn’t have the scholarships or the money to go to college, so I decided to go into the service so I could have the GI bill and go to college when I got out, not wanting to add another burden on my mother. Now at 12, Amy was developing. At breakfast on my last day at home, she was wearing her normal night clothes, one of my old football jerseys, that covered her to her knees, and I noticed she had nice little boobs starting. Her nipples were hard making little tents in the cotton cloth. There were lots of tears as they dropped me off at the induction facility, where I raised my hand and joined the US Navy. Boot camp was a breeze, and my “A” school was easy. With a strong background in math and science, I worked on a nuclear power plant aboard an aircraft carrier for six years, gaining rank quickly. At the end of my enlistment, I was offered the opportunity to go to OCS where I could get my college degree and become an officer, but I turned it down and got out. I had received a letter from Mom, at least once a week, and letters from Amy three or four times a week, filled with news from home. Amy’s letter always ended, “From your little girlfriend, Love Amy.” On my locker, I had a real estate flyer with a 4 X 6 picture of my mother on it, and 6 school pictures of my little sister. Her senior photo showed her in a black shoulderless dress, which showed very nice cleavage. My little sister was not so little anymore. Amy was also very smart. She never said anything, but Mom was very proud of her daughter’s accomplishments and told me everything. Amy was voted Homecoming queen because of her beauty, but she was also going to graduate number one in her class because of her brains. She was much like me in that she loved math and science. She had gotten several scholarship offers from major universities and was yet undecided about which offer she would take. The best offer was from Georgia Tech, but Tennessee was in the running. She wanted to study electrical engineering and computer programming and while the best schools for that were in California, she didn’t want to move to the West Coast. I had decided, now with the GI bill to help me, I wanted to go to school and study architecture, but with my training in nuclear power, engineering was a strong possibility. With only six months remaining in my enlistment, I wrote off for my high school transcripts and started applying to different universities including the university closest to our home in Saint Louis, Missouri. My only problem was Mom. I was still in love with her and had been away from her for six years. I didn’t want to leave her again and Missouri didn’t have that strong of a program in Nuclear engineering.

By saving up my leave, I was going to leave the Navy early and return home in time to take Amy to the senior prom, as she requested, and be there for her graduation.

I had only returned home on leave once in the six years of my enlistment and it had been very difficult to leave after two weeks around Mom. My room was just the same, and I found myself sitting on the floor of my closet pumping cum into an old sock as I watched my mother masturbate herself to sleep every night. Still, after all this time, I had never found a woman that equaled my mother, in personality or looks. She was the only woman I wanted. If I could, and she would accept, I would marry her and live happily ever after, but I knew that dream was impossible. I thought that by staying away from her, I could get my mind squared away, and find someone else to love, so I returned to my ship and tried to fall out of love with her. It didn’t work.

I didn’t tell them the exact day of my return, allowing me to surprise them. I slipped into the old house at six in the morning and made my way to the kitchen. Mom woke up to the smell of fresh coffee brewing and slowly followed her nose. When she rounded the corner and saw me filling my cup at the counter, she screamed and threw herself into my arms. This woke up Amy with a start. She rounded the corner to see what was wrong and joined Mom by wrapping her arms and legs around me, smothering me with kisses, and crying into my neck. Amy joined Mom at the stove to make breakfast for us. Mom was in a thin nightie, showing all of her curves. As she moved around, I knew she was braless because her boobs moved freely under the thin covering and her nipples were hard. Her ass was just as tight as the first time I had seen them and were legs were muscular and shapely. She had not changed a bit. Amy, on the other hand, had changed a lot. She was still wearing my old football jersey, but now it was worn very thin and displayed her boobs nicely, showing hard little nipples on top of C cup tits. The shirt didn’t cover her ass or her white cotton panties, displaying her pussy and a nice camel toe. It was difficult to eat with a raging erection and trying not to stare at four perfect breasts.

Mom called her office and told them she was taking the rest of the week off, and we spent the rest of the day hugging, kissing, and talking. That evening, I took my best two ladies out to dinner and dancing. As we moved around the dance floor and I held them tight to me, I could feel their hard nipples boring into my chest, and I noticed both of them grinding their pussies against my hard cock during the slow dances.

After kissing them both goodnight, I quickly stripped nude and went into the closet to watch Mom undress and get in bed. She took off her party dress and I was a little shocked to see she had not been wearing panties all night. She threw herself onto the bed and started masturbating. After a few minutes, she reached into her bedside table to find her dildo, and rubbed it across her wet pussy, moaning all time. It didn’t take long before her knees were raised almost to her armpits and she thrust the rubber dong deep into her pussy and moaned loud enough for me to hear her clearly, “God, Mathew, Fuck me. Fuck me deep, Son.” Finally, she almost screamed, “Please fuck Mama!” and exploded in orgasm. I wanted to rush into her room and tell her, her wish was my command and jump on top of her, but my cum was hitting the wall of the closet and making another sticky spot on the floor at the same time. Once was not enough for either of us. I continued to watch her as she traded the dildo for a vibrator and came three more times before she turned off the lights and went to sleep. I woke up several hours later, crawled out of the closet, and got into bed.

I started leaving my bedroom door cracked hoping one of them would see me, and join me in my bed. I also started leaving the bathroom door cracked hoping that someone would climb in the shower with me. After lunch on Friday, Mom said she to run into the office to handle some last-minute paperwork for a house sale. I had been working in the yard all morning so I headed for the shower. Mom had remodeled the bathrooms, while I was gone, and the big old tubs had been replaced by beautifully tiled shower stalls with half-glass enclosures and an open doorway. While washing the sweat off, I noticed movement in the mirror. Amy, still in her nightclothes, was standing in the doorway. Her panties were on the floor at her feet. Her left hand was under my jersey pulling on a nipple and her right hand was strumming her clit. I soaped up my semi-hard cock and stroked it to its full 7 ½ inches. I leaned back against the tile wall, raised my left foot onto the shower seat so my balls could swing, and started pumping my cock for our pleasure, making sure she had a clear view. Amy widened her stance and masturbated faster, unaware that I could see her in the mirror. Just as I shot my load against the glass, she put her left hand in her mouth to keep quiet and I watched as she orgasmed. It must have been a big one because she had to put her hand on the door frame to keep from falling down.

Saturday was Prom night. Mom and Amy wanted everything to be the perfect date. Mom told me to go along with anything Amy wanted to do. She had been planning and looking forward to going to prom with her brother ever since I had first proposed it to her in a letter during her freshman year. At the time it was just something nice to say to my little sister, expecting her to have a boyfriend by her prom and forget about my promise. But she didn’t have a boyfriend, and she hadn’t forgotten my promise. Mom took her out to get her hair and nails done and picked up the prom dress from alterations. I was to wear my dress uniform, which I had to pick up from the cleaners, and flowers for my date and her mother. I showered, dressed, and was waiting for them in the living room at six. Wow, Amy was drop-dead gorgeous. I carefully pined on her flower and tried unsuccessfully not to stare down her cleavage.
