The last year I turned 21 and everything started to happen all at once, as if all my life I was waiting for the beginning and finally there it was. Last year my mom Estella, for all intents and purposes, left my stepfather. He's a total dick who is borderline insane, bi-polar, and a womanizer. He had it coming. They were married for 6 years, with him being sweet and charming in cycles, and then being a massive, controlling dickhead for the rest. Twice she'd left him, but for complicated reasons she went back...and he promised he would change. Of course he was lying through his teeth. Now she's left again, for good. Hoorah! I heard the news of divorce from my mom on telephone because I was living away from home for almost two years. I wanted to know more but mother asked me to come and meet her, as there are lots of other things worrying her. On reaching home I found mother living alone. She was now past forty but still has the face of woman many years younger than she actually is. I did admire her figure; her tits were small with almost no sag, her thighs and ass firm. Her dark brown eyes are large and warm and her tummy has just the right amount of bulge to it. The next news given to me by Mom was that my nineteen year old sister Juliana had married a man old enough to be her father. I was really shocked to hear because in my eyes my sister was smarter than me. I still asked why my sister did such a silly thing. To this my mother said that Juliana's boyfriend made her pregnant. That son of bitch betrayed her as soon as he learned the news of her unwanted pregnancy. Luckily or unluckily a divorced friend of family knew about her state and asked her to marry him. As he has no child from his first marriage he was ready to adopt my sister's child as his own. 'Does Juliana have another choice?' Mom asked me and I felt that I could not answer this question. All at once, it seemed like people had decided to tell their lousy secrets. My real dad, a longhaired, door- to-door household cleanser salesman too, unburdened himself to me in a convertible a few blocks from my mother's house, telling me that he's a faggot, after all, not even bisexual, but purely gay, despite the fact that he married my mother and, evidently, had sex with her at some point. Although he pretended that he didn't know I'd been kept in the dark, it was, in fact, a secret and came as a complete shock. I remembered the time when my parents divorced each other. I was fourteen then and still considered a child. None of my parents felt a need to tell me anything about their divorce. Mom sometimes asked Juliana and me to lye with her when she was relaxing. I remembered that during that period mother gave up on the string of so-called boyfriends who followed the divorce -- before she married the dentist, Peter Starke, when I was sixteen. By the time I turned eighteen all of us that is Mom, Juliana and me realized that Peter Starke is a burden in our lives. I never got the girls because of I had a complex of a smaller cock. I've never known what to say to girls. I ended up telling them about something I've read, or some tiny, useless fact that I heard somewhere. I asked my mom in the kitchen one morning, "Do you think I'm good-looking? I mean all the genes are there." "Men don't have to be good-looking," said my mother, "The world is ruled by ugly men married to beautiful women." I took a sip of juice and asked again, "But am I good- looking?" This time she ignored my question altogether and asked, "Are you having sex or not?" "I don't think I have to answer that," I said, My mother looked at me. "You should have sex." I was meeting my mom after a short break but it had begun to dawn on me how strange she really was becoming. She seemed to be two very different people. In the daytime, she was amply gracious, refined, generally connected and straightforward. But she rarely slept -- because she suffered from terrible nightmares that made her wake up screaming. I just wanted to cheer her up. One day I saw mother standing in front of the dressing table with her back to me, brushing her hair. She was wearing one of her shortest and sheerest gowns and it showed off her exquisite figure to an extent I never imagined possible. It was black and silky, and so damn short that it hardly covered her tempting behind. My cock began to swell uncontrollably. I'd sneaked up behind her and slipped my hands under her arms and grabbed both her tits. At the same time I'd embedded my hard cock in the fold of her dressing gown. Looking back one could hardly call my actions 'subtle' or 'cautious' or even 'measured'. She's spun round, pulled her gown tight across her body, and looked at me in anger. "Rick, don't put your hand there. You must stop touching me! Rick, move your hand... NOW!!" "Oh..." I'd muttered. "I'm... I'm sorry. I didn't think you'd mind. I thought..." "You know what your problem is? You need a girlfriend badly." "Do you know where I can find one"? I asked. "Ask a girl your own age," she replied, "Really Rick, you are a handsome boy. You are witty and intelligent." "You know very well what size my cock is and how I feel about it." "The right girl for you will not care about any of that. She will care about you. Besides a big dick sometimes rubs the insides of a girl raw." "What I learned so far is that it took a monster cock to satisfy a woman." "I don't think this is a subject, we should continue talking about," she finished. *** Next morning I saw mom preparing for a bath I jokingly asked whether she wants me to wash her back. To my surprise she agreed. When I was young my mother used to ask me (or my sister) to wash her back. I even used to take shower with her until she married Peter. As I entered inside the bathroom mom had finished undressing and was turning on the shower. As soon as we were wet, mom turned off the water. Then she turned around and told me to wash her back. Mom's biggest rule was hands were to stay in back and above the waist. The one thing I always did first, was to soap up my dick. I would then accidentally rub it into her ass crack as many times as I felt I could get away with. This morning was no exception. I rubbed it slowly into her bum crack. What she did next was intended to teach me a lesson. She bent down and grabbed my lower leg. Then she yanked it out from under me. I slammed into the shower wall. Since I had my hands on mom's shoulders at the time, I pulled her down with me. As I hit the wall I felt something slide over my dick. Mom yelped as that happened. "That was a mean trick mom," I told her. "Mean nothing," she hissed. "What is mean is that you impaled your dick in my ass." Now the feeling of moist warmth surrounding my dick made sense. I adjusted us so that mom was bent over, with me standing behind her. "Gently, gently," mom kept whispering. I then began to move very slowly in her. "You nasty boy, slamming into a lady's ass like that could really hurt her," she finally said. After a couple minutes of me gently moving back and forth in her mom said, "You can pick up the pace now. I finally got used to having you back there." I picked up the pace. It didn't take long until the friction of her ass against my dick, caused me to come. After I came I remained hard. I asked mom if she wanted me to continue. She did, so I did. It was really a nice feeling, now that I was doing it for the sheer pleasure of fucking, and the urge to cum was temporarily sated. Finally mom told me, "Stop, my ass is really sore." I stopped and we finished our shower. Later during breakfast, I told mom that I was puzzled how she could take Peter's huge dick but have trouble with mine. She told me that it was the difference between her cunt and ass. Also it was the initial violence with which we began. "After all," she told me. "If I rammed even a small rod up your ass it would hurt." Put that way, I definitely could understand her initial pain. "Now, about your spying on Peter and me..." "Mom," I blurted, interrupting her. "I didn't spy. Your door was open." "Well I guess in the future, I will have to be more careful about my door." She smiled to let me know she was joking. "Really, by keeping my door open slightly I thought it would make you horny enough to go after a girl your own age." *** No more sexual contact took place between us all through the day. Both of us tried to act normal until we met again for dinner. Our conversation lagged at that point. We both concentrated on the meal. As usual, mom stuffed herself. Finally she pushed herself back and said, "If I eat any more I will explode." "Go ahead and relax mom. I'll get the dishes." I told her. She mumbled her thanks and left the room. That left me to clean the dishes alone. I was glad to give her some time to get relaxed. Ten minutes later, I entered her room. She didn't disappoint me. There in the middle of the floor she was sprawled out on a blanket. I lay down next to her and placed my head against her tit. "Make sure you don't put any pressure on my stomach," was her only demand. Since her stomach was not what I wanted to put pressure on at that moment, I obeyed her demand to the letter. Her tit on the other hand, well I did push against it with my head. Soon I got daring and placed my lips on her nipple through the thin robe. There was no complaint. Soon I even managed to pull the robe open so my lips could reach her nipple without the robe in the way. When my lips touched her bare nipple her only response was, "Oh, Baby, you really shouldn't do that." Since she did not say stop, I kept going. In the past she had always used the word "stop" when I went to far. We even had joked that stop was our safe word since mom always used it just as things were getting interesting. I merely moved my lips slightly and said, "Wrong safe word." Then I put my lips back on her nipple and started gently sucking it. It stiffened and mom groaned. "Oh baby," she murmured. Then her hand reach down and started caressing my thigh. She stayed away from my dick, but her hand on my thigh was enough to encourage me to continue. I reached down and started caressing her mound. To my surprise she was not wearing panties. Soon my fingers were inside her cunt lips and gently stroking. "You better stop that now baby," she told me. Then she rolled over on her side away from me. I thought it was over, but then she started moving her ass against my body. I took the hint and placed a finger against her rosebud. A soft groan was the only sound she made. My finger, still wet from her cunt, slid in easily. Not wanting a repeat of this morning, when I had rammed into her, I was very gentle. Soon her ass started lubricating. When it was really wet I placed my dick against her. "Not yet baby," mom said stopping me yet again. She took my cock in her mouth and sucked it. She only wanted to make my cock wet. As soon as she dropped a big amount of saliva over its head she let it go from her mouth. "Go gentle at first," mom then said. I did. My dick was placed against her ass, and very gently I started pushing in. Soon I was all the way in. Then I started moving. Mom moved back against me, but her movements were slow. I felt my orgasm start building. "Cum in my ass," Mom demanded. I was only too happy to oblige. Then I shot into her. Shot after shot was sent up her hot ass. "That was great baby," mom murmured. We lay together for a while like that. Then mom's breathing became even, and I knew she was sleeping. There was disappointment that we could not continue, but still I knew how lucky I was to have an understanding mother like mom. I woke up the next morning on a blanket and found that Mom was curled up next to me. Her robe was bunched up around her waist. My penis was resting in the crack of her ass. Remembering yesterday, I started getting hard. I wondered if mom would like to be awakened by my dick entering her. It was tempting, but not tempting enough to risk our new relationship. I thought about what we had started yesterday. Physically it was great. Emotionally it was unsettling. Here she had raised me. Everything from changing my diapers to making sure I was ready for my first date. Now we were lovers. Could I handle that? Could she? And the kind of lovers we were. Would we ever have penis to vaginal sex? I decided that for now my dick would lead. I really did not want to go back to the way our relationship was. So far the sex had been great. Mom seemed to have enjoyed it also. Would she still enjoy it, both emotionally and physically? Mom turning in her sleep interrupted my reverie. Her eyes opened and she looked at me. I could tell she was remembering how we had gotten here. She also seemed troubled. Then she seemed to make up her mind. She put her hand to her mouth and got a large dollop of saliva. She then began rubbing it on my dick. "I cannot make any promises about the future of our relationship, but for now, lets fuck," she told me. It was the best idea I had heard all morning. I tried rolling on top but she stopped me saying, "I do not think I am ready for that yet. You at least are still technically a virgin, and I do not think I should take that from you, but we can have a repeat of yesterday." She then rolled over on her side presenting her ass to me. Since she was ready to let me have her ass, I would take it. I still wanted to have vaginal sex, but for now, that would have to wait. Gently I began working my dick up her ass. Mom loved it. "Fuck my ass," she told me. I started pushing into her harder. "Ram me with that little dick of yours." I wasn't sure if I should be flattered or angry at her comments, but since she seemed to be enjoying it I decided to follow her instructions. I started ramming my dick into her. Mom didn't say anything else. At least nothing that could be understood. I wasn't in the mood for talk either. The way her ass gripped my dick was great. Before long I was coming. I shot up into her so hard that it was almost painful. Soon I began returning to earth. Mom slowly did too. Finally she opened her eyes and smiled at me. "I think that little thing of yours is addictive," she told me. "Now let's take a shower. Just after the shower mom let me look at her cunt closely. She had a delicate mound of hair that I could see surrounding the slightly pouting vulva. It was beautiful, just as I would have fantasized it to be. Not too protruding and yet pouting enough to show a crease clearly building to her mostly obscured clitoral region. I kissed the lips of her cunt with my mouth. She didn't resist at a though I did see a tightness around her eyes then as though she were trying to keep them shut against their will. I stroked her vaginal crease parting the labia gently. Just beneath the surface she was wet. Not moist, wet! With no further ado I dipped my index finger into her. She arched slightly to receive. I pushed it in, soaking it in her juice and feeling her insides. Slick and warm. I began a gentle in out motion that she ever so slightly began to match. There was no turning back I had to fuck her. We experienced vaginal sex that day. Mom's only comment before I drove home in her cunt was, "You really shouldn't, still I have never been able to refuse anyone who did my ass good. After all, the way to my heart has always been through my ass. Now fuck me stud." With her being used to Peter's dick, mine didn't do much for her. I stopped for only the briefest moment before penetrating her to savor the moment then I pushed my penis into her. As I pushed in to full burial she moaned and pushed against me. I grabbed her breasts from either side then and began to fuck her. I squeezed and pinched her breasts now without hesitation and slid in and out of her with bold and forceful strokes. She heaved and pushed with me now. All at once she opened her eyes. I looked down on my mother then and let go just as she found orgasm. I emptied myself deep inside her then. In exhaustion I laid down on her keeping myself still inside her. Afterwards mom did say that I could fuck her cunt anytime. Still vaginal sex isn't our favorite sexual activity. Our favorite is ass fucking, and with my dick being the perfect size, mom says so at least, we do lots of fucking. We still have to come to grips with the emotional aspects of our relationship, but for now the physical part is great.
