My stepmom arrived on the scene several years ago from the West Coast. I knew my dad was going to be a happy man from then on, and you can be sure he was. Rhiannon was her first name, but she went by Rhi. Nonetheless, I came up with the nickname "Rhi" early on, and it stuck. I remember fondly when I used to play basketball with her; my waist brushing against her behind and her girlish smile as she would score the occasional hoop on me.

Though now in her early 40s, Rhiannon still has an incredible body. When she leans over her behind is tight and shapely against the tight black pants she brought with her from New York. Occasionally at the dinner table she would bend over and I couldn't help but look over at those round hips. Four years ago Rhiannon had a baby with my dad. My dad liked to talk about how he was sure she became pregnant on their first try - and I believe it - you could tell she was flushed and plumb with fertility. But that didn't change a thing. She was still as shapely (and I'm sure just as fertile) as ever and increasingly I found myself fantasizing about her.

It started when she'd come into my room at night and give me back massages. Her smooth hands felt like heaven against me, and I could swear that she was trying to be sensual with them, knowing that she turned me on. "Relax, Chris. You're so tense," she would say. I'd fantasize about Rhiannon coming into my room at night when my dad was asleep and sitting on me, I kneading her full, succulent breasts. Her breasts are perhaps her best feature. So big and juicy; I'd look down her bra as she leans over to zip up my Jeans or put plates on the table, in her sweet, motherly way.

My teenage sister was never anywhere near as beautiful as my stepmother. She knew this and became jealous of the attention my dad and I gave to this older woman. Even in my sister's most beautiful years - age 16 or 17 - you could see clearly in a photo of them trying on skirts that Rhiannon had a much rounder, fuller figure, her long dark brown hair flowed gracefully down over her breasts. She is slender, yet her breasts and hips are round and full with softness and that beautifully tender skin.

When Rhiannon was downstairs talking on the cell phone with that sweet sexy voice, I'd find myself in the bedroom soaking up the scent of her bras and panties, listening to her voice and imagining how it would sound under the covers with her smooth, voluptuous thighs on me. Sometimes in the morning when she thought I was asleep she'd walk by my room and I got the pleasure of seeing her full figure; her baby-white skin and those cute little feet thumping softly on the wooden floor. Having the baby several years before clearly hadn't change Rhiannon's hips and butt. Her bottom stuck up tightly against her panties like the16 year-old girls I flirt with at school. I guess it's just nature's way of letting you know that she's still ripe with fertility.

My dad went away on business trips quite often, and I think my stepmother was becoming a little lonely. And her body was so ripe with womanhood, in want of a younger, more vibrant sex life. Indeed, in want of someone she really deserved. One night when my dad was away and Rhiannon was cooking dinner for me, she leaned all the way over to clean up something on the floor, and, my dad not being there, I jumped at the chance to take in that beautiful rump. I could see her pussy lips faintly outlined through her pants. Rhiannon's lovely behind was a foot away from my face! I immediately became hard, and couldn't believe how good she looked. Rhiannon seemed to realize this and righted herself and pulled at her tight panties a bit ( I guess she had a wedgie). She flushed a little and looked at me with her eyes wide, knowing what I must be thinking. She giggled and then smiled at me, then, clearly embarrassed, went to put her young son to bed. That night Rhiannon came into my room with some laundry and a bright, eager look in her eyes. Right then I knew what she had been thinking about that whole evening.

Rhiannon bucked and moaned as she reached orgasm. Her breasts expanded like balloons filling with creamy milk. Her tits bobbed up and down in a way that made me pump her even harder. I cannot describe the way my stepmother made love to me. It was like an injection of intense life through my body, seeping its way through my veins. The sensation of her warm body against me for the first time was a feeling I will always cherish. You see, up until that day, I'd been a virgin, and to suddenly be making love to the woman whom I'd been in love with - a deep, sexual, lusty kind of love, to the point where I was aching for her touch - this was an indescribably wonderful experience. Completely uninhibited, together we vented our pent up feelings for each other in a sweet union of man and woman on that cold, overcast afternoon. My body was warmed inside and out by her sex, contrasting with the cold wind blowing against the bedroom windows.

As Rhiannon and I made love I took in her scent, which was also indescribably wonderful, like flowers and fruit and sweet cream, but with a musty, animal scent that spoke of an intense life boiling in her warm body. Her white skin was moist with this natural odor. As I fucked her, I sucked on her cream-filled breasts, and her tender nipples hardened as I sucked them. She smiled and hugged me, my face between her tender cleavage. I could feel her hear beating. I took Rhiannon's left breast in my mouth as she humped down on me, her smooth thighs rubbing mine, skin on skin, then I pushed her butt against me and traced its curves, from the channel down her lower back to her tight anus, down to her clitoris, where my dick was sunk in to her labia. I felt her plump pussy lips, caressing them while I fucked them.

Then came our climax. As Rhiannon approached orgasm, her body was humping almost violently on me, her breasts jiggling wildly. The sound of skin slapping against skin filled the bedroom. Her voluptuous thighs slammed down on me as the fat in her ass quivered. Her last pumping motions were slow and deep. She wanted me deep inside of her. I felt her juices begin to seep out between our slapping bodies.

My ejaculations were unbelievably strong and sweet. I looked up at my stepmother's beautiful face as I came, her cheeks flushed red with her her internal heat. Her big brown eyes were closed and her mouth open as my penis throbbed powerfully and sperm shot deep inside of my stepmother. It was like our bodies had melted together, joining as one quivering organism. I imagined my dad opening the door and beholding the sight of us on his bed. The plump white rump of his beautiful 41-year-old wife humping down onto her teenage stepson. The arch of her back, with her long dark brown hair that my father so dearly loves, gracefully resting on the curve of her lower back, where, several inches down, her stepson's penis throbbed and injected, balls slapping ass.

In truth, I would have wanted my father to see us. I wanted him to stand there and see how I fucked my stepmother, who'd he'd been married to ever since I was a little boy. She had always been a good mother to me, and with the onset of our love affair that hadn't changed. But a part of me wanted my dad to be there to see how passionately she made love to me, and to realize that he was no longer going to get sex he didn't deserve.

Finally Rhiannon and I were both through, she had milked my balls dry . Cum slowly dripped out of her pussy and seeped into her soft white skin, into her pores. We slept, we fucked, slept and fucked, all through the night and into the next day. I must have reached orgasm ten pluse times. I knew the pleasure Rhiannon was getting had almost overwhelmed her. This was forbidden pleasure, which for both of us made it all the more sweet. She slept with her long auburn hair on my chest, with a voluptuous thigh over mine.

As Rhiannon slept, I'd gently rub that succulent flesh, right at the confluence of her thigh and buttocks. I'd stare at the perfect shape of her ass, firm yet soft and plump. The perfect white of her thigh resting on me was the most beautiful sight I'd ever beheld, indeed, that anyone could ever behold in a situation like mine. She has a little mole right on the underside of her left thigh. She lay on me, her head under my chin. I was in heaven. Right then she awoke at my gentle caress and blushed a little and gave me a girlish smile

Rhiannon moved up onto me and sat on my face. As she leaned over and took my dick in her mouth, her love lips engulfed my face. I breathed in and as she slurped on my cock I took in her pussy's fresh musk. Her plump ass on my face smelled like fresh fruit. I could smell the estrogen seeping from her vulva and as I started pumping my dick down her throat, her lips tightened around it, her tongue giving it gentle strokes. I grabbed Rhiannon's thighs and rubbed them, feeling around to her lower back and down again to her plump ass cheeks, now hugging my face. I sucked on her labia as she purred, "Oh CHRIS, mmmmm." I loved hearing that sweet voice, muffled as it was through 135 lbs. of woman.

I lifted her a little and turned her around and looked down at my dick, wet with her delicious saliva. Her pussy was just as wet as I mounted her from behind, sliding in and out of that beautiful ass. We rocked back and forth as I sunk my inches into her sopping wet vagina, deep, deep, until she squealed like a baby. The combined wetness of her blowjob and pussy juices made a slurping sound each time I penetrated her. As I fucked my stepmother doggystyle on the bed, her plump ass slapped up against me. I savored the feel of those round hips and caressed her love handles as I pulled her gently, back and forth, against my stomach.

This time the sex lasted for quite a while. For a whole 50 minutes I was buttfucking my stepmother, and each thrust into that tight pussy was oh, so sweet. I must have hit that ass hundreds of times, her wet love hole sliding against the sensitive head of my loaded, spurtive young cock. Rhiannon didn't talk while I fucked her, only gave out contented sighs and, as she reached orgasm, began to moan and squeal with increasing intensity. Every time I heard that woman make a sound I sunk my inches deeper inside of her.

I shot my cum deep, and with final thrusts, my youthful testicles slapped up against her skin making a slap, slap, slapping sound that echoed down the hall where my little brother was sleeping. Her ass bucked with orgasm after orgasm. I creamed her and have never ejaculated like that before in my life. I must've at least tripled what I usually can muster by masturbating. There was so much of my young love juice that it filled up her insides and forced its way out of her pussy and onto the sheets, seeping in and sticking on everything, making a generally slimy, sexual mess.
