I closed my eyes, my hands rubbing my large, naked breasts as I lay in bed. I had woken up horny again. I felt like a teenager instead of a woman of forty. For the last two weeks, ever since Cheryl Elliston showed up at my gynecological practice pregnant, planting the ridiculous notion that she had been knocked up by her own twenty-year-old son Clint, I had been thinking of my own son, and not in a motherly way.

James was nineteen, an athletic, handsome, young man. His eyes these wonderful shade of blue, only adding to his boyish charm.

Just thinking of my son sleeping down the hall made my pussy hot. I could go to him, wake him up. My hands caressed my breasts. They were big and soft, the type of tits that young men were infatuated with. I had seen him glancing at them a few times when I wore a blouse too low cut, something I did more often now.

I groaned, my fingers caressing my dark-red nipples, standing up straight as my thighs rubbed together. That hot itch demanded I do something about it. I had to cum. I groaned again, twisting my nipples. These lusts were driving me wild. I knew they were wrong. He was my son. I carried him for nine months. I gave birth to him.

I created him.

And now I wanted to fuck him. A depraved switch had been flipped, turning my maternal love into lust. I shuddered, moaning, my head rolling from side to side on my bed as I kicked off my covers. I licked my lips, closing my eyes.

Fantasizing something so taboo.

In my fantasy, I walked naked down the hallway, passing my eighteen-year-old daughter Jenny’s room. My breasts bouncing, my hips swaying, my pussy burning. I reached my son’s room, opening his door slowly, carefully. I didn’t want to wake him up. Yet. I was such a wicked mommy. I crossed to the room. He slumbered in the dark, covered by his blankets, lying on his back. He slept without a shirt, and I could see a part of his muscular chest.

I reached his bed, pulling down the blankets. Imagining his chest, I twist my nipples harder. I groaned, picturing his muscular pecs and rippling abs as I pull the blanket lower and lower, exposing the boxers he slept in. I did his laundry. I knew them all. Today, I imagined the white one with pirate skulls and crossbones, his cock already half-hard like he knew Mommy was here to teach him how to be a man.

My fantasy was so wicked. I was so hot. I couldn’t resist any longer. My right hand shot out to the nightstand, grasping the pink dildo I left there. I had masturbated before falling asleep to James. I needed to get this taboo lust out of my system. I needed to find a young stud. I was a cougar now. I could find a guy in his twenties, fuck him hard, and banish this from me.

But I had my practice, my patients. I had my kids to take care of. Where was the time to go out and get laid?

I pulled the dildo to my lips while I fantasized about pulling down my son’s boxers, exposing his half-tumescent cock. It would be so long and thick, the crown darkening as blood flow increased. I grasped it, stroking it. Precum beaded the tip. I leaned down, licking it, gathering the salty treat while I licked the dildo, pretending it was his cock.

I moaned, the fingers of my left hand twisting the nipple as I lock my lips about the dildo, tasting traces of my sweet musk. I shuddered, back arching as my fantasy progressed in my thoughts, my son coming awake.

Mom, he groaned in my thoughts. What are you doing?

Shhh, honey. Mommy’s just making her big, strong man feel sooooo good. Mmm, let Mommy show you how to be a man.

The thoughts made my pussy clench. I sucked harder on her dildo, imagining the sounds my son would make as I blew his cock. The moans, the groans, the grunts. The pleasure would twist across his face as he trembled on the bed. He would try to hide how much he liked it. But, in the end, he was a virile, young man and my mouth was so hot.

He wouldn’t resist.

His hands would shoot down, grabbing my dyed-blonde hair. He would grip it as I bobbed my mouth. I pressed the dildo deeper into my mouth, then pulled it out, sucking on it, swirling my tongue while I imagined it was my son’s cock hard and hot and throbbing.

Oh, Mom, wow. That’s…Oh, wow, that’s amazing.

Mommy just wants to show you her love.

Yes, Mom, show me your love. Oh, yes. You’re amazing. You’re the best mom. Fuck!

I sucked harder and harder, his chest rippling. My own pussy was so hot, so juicy, begging to be filled by his cock. I popped my mouth off the dildo while in my fantasy I popped off his cock, moving, straddling his cock and bringing it to my hot, dripping pussy.

My son’s dick!

I nuzzled the hard end of the dildo along my pussy lips, sliding it through my brown bush. I nudged my clit, shuddering, picturing the rapt lust on James’s face as he stared at my pillowy breasts swaying as I prepared to ride him.

Mom, he groaned in my thoughts. You’re really going to do this? You’re really going to be the first woman to ride my cock?

Oh, yes, Mommy has to make her boy into a man!

I jammed the dildo into my pussy.

I imagined impaling my cunt on my son’s thick cock.

The shaft filled me, stretching my hot hole. The friction sent naughty heat rippling through my body. My cunt clenched on the dildo, pretending it was my son’s cock. I groaned, pumping it in and out as I fantasized riding James’s cock, sliding my cunt up and down his dick, reveling in the incestuous moment of a mother teaching her son to be a man.

It would be so hot. My hands would run across his muscular chest, feeling his strength, while his hands would grope my breasts. He would squeeze my pillowy mounds and pinch my nipples. My pussy would clench on him.

Do you feel how hot Mommy is for your big cock? I moaned in my imagination.

Yes!

And you love it. You love being back in Mommy! Back in the pussy that birthed you!

It’s so hot, Mom!

It was so hot. I pumped the dildo faster and faster in and out of my cunt. It churned my juices, rippling passion through me. I writhed on my back, gripping the base of the dildo with both hands to plunge it in with such force, my big breasts bouncing, lost to the incestuous fantasy of fucking my son.

Heat burned in my cunt as I rode James’s cock. His hands squeezed my tits, pinching my nipples. My pussy clenched on his dick as I slid up and then I groaned as I slammed down. He shuddered, face twisting with passion, loving every moment of being inside his naughty mommy’s pussy.

Yes, yes, yes, Mom, you’re so amazing. Your pussy! I love it. I love you, Mom!

And Mommy loves her big, strong son. Oh, yes. Mommy raised a man with a huge cock. Oh, Mommy loves your big dick. Mommy’s going to cum so hard on your dick!

I was going to cum so hard. I plunged the dildo so hard, so deep into my pussy. I reamed my cunt, trembling, groaning, spasming on the bed. It was so intense. The fantasy burned so hot in me. The fact it was wrong, illegal, forbidden only made it hotter. Made me wetter.

Made me cum harder.

“James!” I moaned, imagining him cumming into my depths, groaning, flooding me with his incestuous seed. I shuddered, bucking, writhing, plunging the dildo into my spasming depths. “Oh, James, yes!”

The orgasm burned so hot through me. So passionately. I groaned and shuddered and moaned. I kept fucking the dildo into my convulsing pussy, lost to the taboo urge to fuck my son. To feel his cum splash into my depths. It would be so wonderful to feel that creamy delight spilling into me.

Knocking me up like Clint knocked up his mother.

My body bucked. My tits bounced as I convulsed so hard. A second orgasm detonated in me. I moaned my son’s name over and over as the pleasure burned through my mind. My entire body heaved. Rapture burned through my mind.

I wanted to fuck my son.

My orgasms peaked.

And then the guilt crashed through me as I collapsed into a panting heap, gasping for breath. What was wrong with me? Why did these thoughts plague me? Why was I such a bad mother?

Jenny Wilson

I trembled on my big brother’s lap. We were in his bedroom. It was early in the morning. We both couldn’t sleep. My period was two days late. If it hadn’t arrived by this morning, I knew there was only one possibility. And the pregnancy test clutched in my right hand confirmed it.

I was bred by my big brother.

So many emotions roiled through my stomach. I was scared and happy and excited and nervous and horny and frightened and ecstatic and so much more. They all mixed and swirled. I was pregnant. I was eighteen, pregnant, and knocked up by my own brother. The brother who loved me. The brother who would support me. The brother who was happy I was pregnant, his hands squeezing my ass through my nightgown, his cock growing hard beneath me as he kissed me. I clutched to him tightly, kissing him back.

The last two weeks had been magical. It really wasn’t surprising I was pregnant. Maybe we could have gotten away with him cumming in me the first time without a condom. Even if it was in the middle of my cycle, the most fertile time of the month for me. But that was the excuse we used to keep fucking, over and over. After all, he might have already knocked me up. “We’ll wear condoms once you have your period,” he kept saying as he slid his dick into my wet pussy. “But until then…”

“Let’s enjoy ourselves,” I would moan, loving his dick.

And we had. We had all kinds of sex. At home and even at school, enjoying quickies whenever we could. We were both so horny, so in love. It was wonderful. He was wonderful. My big brother was amazing. Awesome. The best big brother in the world.

Better even than Clint, even if he did fuck his two sisters, his two cousins, and maybe his aunt and even his mother. Mom told me his mother was pregnant, which was very suspicious to me.

I broke the kiss with James, staring at his blue eyes as I trembled on him, squirming, my pussy so hot.
