My Step-mother

Fiction
I was pissed when my dad married his new bride; angry because she was fifteen years younger...than me! In fact, she'd just graduated high school two months ago. It made me wonder how long they'd been seeing each other and why a seventeen year old would want to fuck a man in his fifties let alone marry him.
To make matters worse, my wife of ten years had just left me for an older man, so I was feeling a bit angry, hurt and betrayed on all sides. Since my wife had gotten the house in the settlement, paying me a handsome sum for my half, I was currently living in Dad's basement while my new home was being built. I was a self-employed writer, making a tidy sum of money from residual sales of over fourteen best sellers in the past twelve years.
You see, I write mainstream erotica. Not something poorly written like the fifty shades, but well written short stories and some much longer sequels that packaged quite well into longer novels. My audience never seemed to fail when it came to pushing one of my newer works to the top of the best-selling list. Then, for reasons unknown to both myself and my publisher, they stayed there for over two years before slowly declining into a flat level sales performance.
I've never really written much from experience, choosing rather to draw on my wicked imagination and toss in current events to make it seem more real. I was in the midst of a short story anthem of deliciously wicked tales when my "step-mom" came to the basement to do the laundry. Through the hinge side crack in the door I saw she was wearing her favorite outfit: a thong and matching bra ensemble that left very little to my devious imagination.
I see why my dad snatched this beauty up, but what did she ever see in him? I filled my corneas with her before finally turning back around to my job. As I was writing a particularly erotic section, I heard her enter the room. She was noiseless, but the background ambient sounds changed as she slithered in. Then she was looking over my shoulder as I typed away at te keyboard, wicked wonderful words were translated from my mind to the screen via my fingers and keyboard. She read each one as her hands settled on my shoulders.
I was already keyed up by the writing, as most erotica authors will tell you. Since I was single and this woman was clearly able to handle more than one man at a time, I let the energy from her hands work through my body and into the story I was writing. She began to knead my neck as the words heated her up. I could already smell her arousal and I wondered if I'd get to see what my dad found so enticing in Marybeth, despite the fact that she had a gymnast's body and that young girl look. Hell, she was still seventeen, having gotten written permission to marry my father. The age of consent here is sixteen, so their sex had been lawful, but the marriage was not, except by the consent given by her mom and dad. It made me wonder what my dad gave them in exchange for that permission slip.
I took a pause in my typing, pulled my hands from the keyboard and stretched them backwards to either side of her thin little body. My head tipped back against her barely A cup tits as I looked up into her downcast twinkling eyes. A playful smile teased at the corners of her mouth as she bent down till her lips touched mine. I wanted my step-mom and I was going to have her, right now.
In what could only have been a pairs skating team move combined with a gymnastic maneuver, I lifted her eighty-two pound body up and over, twisting her one hundred and eighty degrees till her thong-clad crotch was now in full contact with my boxer short encased cock. She smiled at the move and then gasped at the cock trying to find its way inside of her through two different layers of cloth.
I pushed away from the desk, looking into the eyes of a hot teenager. She took one of her arms from around my neck and slid the thong aside, "Your turn...stud."
I wasted no time in grasping my erection and guiding it out the front hole and against her swollen and very wet labia. She rocked her hips forward, engaging my penis before she slid her feet forward enough to gain more purchase on the computer chair so she could fill her cunt with my cock. She slid her well fucked pussy onto my cock until she had all seven inches inside of her, "You're thicker than your dad."
She controlled the action, slowing when she wanted, fucking hastily when she needed and sensing when I was going to blast off, she stopped...edging me until she was ready for me to cum. I got nothing written for three and a half hours that day, but I got story fodder for three books. When she finally let me cum, it filled her to overflowing. A puddle of cum stained my computer chair seat, but it was worth every last drop.
After that day, she would come downstairs at some point in time and fuck me. Dad never let on that he knew, so we never suspected anything and took precautions so that he'd not find out. After two months of our affair, she wanted to try something new. She wanted me to take her anal virginity. It was painful for her with all the stretching and gauging, but eventually I was able to cram my cock into her ass, ride it for a while and then make the first of what became a daily anal cre pie. She would let me fuck her face, then her pussy and finish in her ass. I know dad fucked her often because I heard them as I stroked my own cock before going to bed. The girl was just what I liked...a slut.
I don't use the word slut as a derogatory descriptor but rather a compliment. I'd rather have a slut over a virgin any day. Give me a girl who's had ten, twenty, a hundred guys. Hell, give me a girl who is the biggest cum dump and I'd be happy. At least she'd know how to please me and she wouldn't' be a prude about it.
Marybeth was about the best a guy could get and I saw why dad married her, but I still didn't understand why she did. I had finally gotten my house finished and was getting things packed to move out. He and Marybeth were having their nightly go at it when all of a sudden I heard her sobbing. I dashed into their room, naked, having forgotten about my state of clothing and found my step-mother still sitting on his now lifeless cock. She'd fucked him to death.
I found presence of mind and helped her down off him and into my arms. To this day, I can't explain why it happened, but she climbed me like a tree, impaled her pussy with my main branch and fucked me until she came. Then she climbed off and put a bathrobe on and called 9-1-1. I too put a bathrobe on and waited with her till the officials arrived. It was determined at the scene that Marybeth's story was born out by the facts. Dad's body was taken to the funeral home of his choice and we set about together to plan his burial.
A week following his death, we stood with our families and watched as he was lowered into the cold ground. I took my step-mother home so we could endure the reception afterwards, food from everywhere had arrived and it would take a week to make it disappear. After the commotion, and Marybeth assuring her parents that she'd be ok in this big house alone, we found ourselves alone again.
We joked about dad, and she even was able to tell me about how they'd met. Then she told me why she'd married him, "As you know, your dad frequented all the schools as a fire extinguisher inspector. He had the state contract. He and I met two years ago, about the time that you and your wife started having trouble. A month later, I started fucking him. He took my virginity, and I gave him a new lease on life."
She continued, "He was a great lover, but not as good as you. He was careful and kind. He helped me with my schoolwork and insisted that I get good grades. When I turned seventeen, he asked me to marry him. He told me that he had cancer and wanted to have a young pretty wife that really loved him and showed it. I did you know...love him?"
"Yes, I know."
"When he proposed and I accepted, he laid out a further wish for me, if I was agreeable to it. He told me that you and your wife were going to be divorced. He wanted me to try you on for size before he passed away from his stage four cancer. Even with his pending death he was hoping to provide you with some happiness."
I had tears in my eyes at dad's efforts...and Marybeth's cooperation.
"Your dad willed everything to me regardless of the outcome. With or without you, I still got it all, but after that first day when we started our affair, I knew I wanted it to be with you. He and I talked about it every day. He wanted to be dead sure that I wasn't just doing this for him but that I truly loved you."
I was in a full on sob now, missing my dad immensely.
Marybeth opened her wrap-around black dress and snuggled her tiny tits around my face, "Cry baby, momma is right here to soothe you. Daddy will always be right here with us, as we carry on his legacy. If you didn't already know, I'm pregnant with your child. Dad had a vasectomy so it has to be yours, even though you both fucked me bareback every day."
My mood brightened a little with that piece of news, having been previously married to a medically barren wife.
"My mom and dad already know what the score is here and they are totally onboard with it. They just want to be sure that you won't have any problems marrying your father's widow, or rasing your child with her. They also want to make sure you won't have any issues marrying a girl who is just barely sixteen."
I looked up from between her tear soaked tits, "Marybeth, you could be fifteen and I'd marry you. I love you. I lust after your tight hot little body. I adore that you are carrying our child and if your mom is any indication, I'm sure you'll be right back to your high school weight in no time."
She smiled at me, "Good; I'm glad that's settled. As for my figure, my mom had three children and she's the same size as she was in high school, fifteen years ago. Mom was a young mother and bride as well. She had me when she was fifteen. My dad was twenty-two and they were allowed to get married before I was born."
Something finally registered in my mind, "Hey wait...you said just barely sixteen?"
She smiled coyly, "Yes, you dad never really knew it, but I'm fifteen. Daddy got a forged birth certificate and driver's license for me. I'm in advanced classes in school because I'm gifted mentally. So technically, you've been fucking a fifteen year old for the past few months and you'll be marrying a sixteen year old in a few more months. But so far as everyone else knows, I'm almost eighteen. Does that freak you out too much?"
I picked her up and placed her young self on the kitchen island, peeled off her dress and spread her sweet thighs. My face was between her legs in no time, feasting on the best tasting pussy I'd ever had and probably ever would have. Her screams of ecstasy filled the house as she pulled at my hair, keeping my face in contact with her bucking hips.
It's been ten years since we married and we have four lovely children, all girls. Marybeth is still a size zero with a killer body and I'm still rock hard every night and sometime several times a day. Our girls all know our story and hope one day to find their man, even if they are too young to be legal. Paperwork is easy to find, and falsify. One just has to know the right people. They were included in dad's paperwork as well.
