Skip to content I was twenty-four years old with a son and a daughter. Life felt pretty good at the moment. My wife was away at her sister’s place with the kids, so I had the house to myself for a few days. The quiet felt strange at first, but I didn’t mind it. It was nice to breathe for a while.
My little sister had called earlier and said she wanted to stop by. Her voice on the phone sounded tense, like she had been crying or holding something in. That alone made me worry.
My little sister Chloe was twenty-one. She had that natural next-door beauty that didn’t need makeup to stand out. Her chestnut hair framed her fair skin and hazel eyes. She had a figure that drew attention without her trying, with curved hips, a small waist, and a heart-shaped butt she inherited from our mom.
She loved simple things like horseback riding, long walks in the forest, sketching flowers, and reading on the porch when it rained. She was quiet and a little shy, but she had a warmth that made people feel safe around her. No matter how busy I was with work or family, I always made time for her. She was my little sister, and I loved her deeply.
When I heard her car pull into the driveway, I got up from the couch and opened the door before she could knock. She stood there in a fitted blouse and jeans that hugged her hips, and a pair of glasses. Her lips curved into a small smile, but it didn’t quite reach her eyes. Something was wrong.
I stepped forward and opened my arms. She hesitated for a second, then melted into the hug, her body pressing against mine. Her warmth lingered through her blouse, her heartbeat steady against my chest.
“How’s it going, Chloe?” I asked.
“Bad,” she said quietly, her face still against me.
I pulled back just enough to look at her. “Let’s talk about it,” I said, leading her inside.
Chloe slipped off her shoes by the door while I closed it behind her. She looked tired, the kind of tired that came from more than just lack of sleep. I guided her to the couch, but she asked, “Can I have some tea first?”
“Of course,” I said. “Same one as always?”
She nodded, brushing a strand of hair behind her ear.
I went into the kitchen and put the kettle on, pulling out her favorite chamomile blend. She had been drinking it since high school, usually when she was stressed. When the water started to steam, I poured it into a mug, added honey, and brought it over to her. She took it with both hands, breathing in the warmth before taking a small sip.
“Thanks,” she said, her voice quiet.
“Anytime,” I said, settling down next to her.
For a moment, she just stared into her cup. Then she asked, “Did your wife ever have fertility issues?”
The question caught me off guard. “No,” I said after a pause. “She got pregnant the first time we slept together.”
Chloe let out a long sigh and set the cup down on the table. “Lucky her,” she whispered. “I want a baby too, but I can’t seem to get pregnant. I’ve been trying for months with my boyfriend, and nothing’s happening.” Her voice trembled at the end. She looked away, blinking rapidly as her eyes began to fill with tears.
I leaned forward, resting my elbows on my knees. “Hey, don’t get upset. You’re still young. You don’t have to stress about that now.”
She shook her head. “That’s the problem. I should be fertile enough to get pregnant. Every day that goes by, my chances get smaller. He keeps saying it’s my fault.”
Her words hit me harder than I expected. I reached over and took her hand. “You don’t know that it’s you, Chloe. It could just as easily be him. Sometimes guys have issues too.”
She sniffled, looking down at our hands. “He says he’s fine. He says it’s me. He shames me for it, like I’m broken.”
“Then he’s not the kind of man who should be having kids with you,” I said firmly. “If he’s going to shame you instead of standing by you, that tells you everything you need to know.”
She chuckled awkwardly and wiped her cheeks. “You always make things sound simple.”
“Because it should be simple,” I said. “You deserve someone who actually cares, not someone who makes you feel less than you are.”
Chloe nodded, sniffling again, her eyes still red but softer now. She stared at me for a long moment, her eyes still wet with tears. “Would you… Would you try with me? Just once?”
My entire body went rigid. “What?”
“Please,” she whispered. “I need to know if it’s me or him.”
I shook my head slowly. “Chloe, we can’t. We’re siblings.”
“I know,” she said, her voice breaking. “But I need to know what’s wrong with me.” Tears spilled down her cheeks again, her shoulders shaking. Something twisted inside my chest watching her fall apart this way. I had always been there for her and always protected her.
“Please,” she begged again, her voice so small. “Just once. Just to know.”
“Are you absolutely sure?” I asked, my voice barely audible.
She nodded, wiping her tears. “I just need to know if I can get pregnant. If there’s something wrong with me.”
I took a deep breath, feeling the weight of what she was asking and what we were considering. “Now?” I asked.
Her eyes brightened slightly. “If that’s okay?”
“Alright, let’s go,” I said, making a decision I wasn’t sure whether I’d regret or not. I stood up, offering her my hand. She took it, and I led her upstairs to my bedroom.
“No one can ever know about this,” I said, closing the door behind us. “Not ever.”
“I promise,” she whispered, already looking relieved that I had agreed.
Her fingers trembled as she began unbuttoning her blouse. I wanted to look away but couldn’t. She slipped it off her shoulders, revealing smooth skin and a simple white bra. She unhooked it, exposing small, perfect breasts with pale pink nipples. She continued undressing until she stood completely naked before me.
“Damn, you’re beautiful,” I said truthfully. Her body was youthful and natural, with curves and soft skin that had never known childbirth. A light dusting of freckles crossed her shoulders, continuing down to the swell of her breasts.
I removed my own clothes, shocked to find myself already hard. The situation, the taboo of it all, had affected me more than I wanted to admit.
Chloe’s eyes widened slightly. “You’re… bigger than him,” she said, reaching out hesitantly to touch me. Her fingers wrapped around my length, stroking gently. Our first incestuous contact. “Everything about you is bigger.”
I reached for her, my hands finding the curve of her waist, pulling her closer. Then I pressed my lips to hers for the first time, enjoying the smoothness and sweetness of her lips. We kept kissing, slipping out our tongues while our hands roamed over our bodies.
Then we fell onto bed together. Coming off her lips, I spread her legs and sat right between them. I aimed my eyes at my sister’s pussy. Beads of honey clung to her lips and glistened. With my right hand, I took the head and rubbed it up and down the wet slit, covering it in her honey. I felt sparks immediately, a forbidden thrill. I pushed the head inside, making her eyes widen. I shouldn’t be bareback in my little sister, but here we were anyway. When the head disappeared inside her, I realized how good it felt. It was a forbidden sensation unlike any other. I slowly pushed in a couple of more inches till I reached the thickest part of the girth.
She gasped. “Oh.”
“Relax,” I told her and stroked her legs. I slowly pushed it a bit deeper. I had never been in such a wet vagina. She showed off the fact that she was at the peak of her fertility and not an infertile girl. I saw the pain on her face as my girth stretched her, but she slowly let go. The pain faded to pleasure. She wrapped her arms around my back and even pulled me toward her.
“Hmm,” she moaned and leaned back. “Oh, big brother.”
She strangled me, and I decided to linger inside her, savoring the sensation of having a part of her wrapped around me. Her wetness made it easy for me to slide all the way out till only the head remained. “How does it feel?” I asked her.
“I love it,” she said, biting her bottom lip.
“You want more, don’t you?” I asked her while keeping the head poised at the entrance.
She nodded eagerly. “Just push it inside.”
I slowly thrust my hips into her, sending my massive cock deeper and deeper. She gasped again. It felt so good that I couldn’t hold anything inside. I kept pounding her missionary while my eyes were glued to hers. It must have been the sweetest pussy in my life, and I enjoyed every second and sensation of it.
“Oh, Nathan,” she whimpered as her hips bucked harder and her pussy tightened around me. Her mouth kept widening as she stared at my cock sliding in and out of her.
I knew she enjoyed every second of it. My pain was hers, and her pleasure was mine. Her fingers dug into my spine, and she looked into my eyes. I kept growling and grunting and stretching her youthful pussy. I wasn’t many thrusts away from the climax. There weren’t many pussy strokes left till I would burst and fill her interior with my cum, marking her territory with my semen and also impregnating her.
“Oh,” she moaned and held onto me as if afraid I would vanish. “Please, don’t stop.”
“I had no plans to,” I grunted as my toes were already curling, and the orgasm was building, second by second. I kept fucking her, hunting for that sweet friction that just got sweeter for every thrust.
I managed a few more hip-thrusts before my balls tightened like fists. They then let go and released their contents in thick, hard blasts. I felt my orgasm race through the crown of my cock when I exploded inside her. I groaned as hard as I could, and the explosion felt stronger than Big Bang as I’d never felt anything so thrilling. We both moaned simultaneously as her tight entrance milked my spurting cock. She turned her head, her lips meeting mine. “I want every drop,” she whispered into my mouth as if she were obsessed.
“I’ll give them to you,” I told her, micro-fucking her as she continued to move her hips.
Coming down from my high, I noticed a gush of her juices flooding my cock too. Goosebumps flared across her petite arms, and her nipples stiffened to the point of daggers. I could tell I’d brought her to the peak as well. We’d gone there together, hand in hand, like two siblings. I rested inside her while catching my breath, savoring the sensation of having her taboo womanhood wrapped around my cock.
I was about to pull out, but her pussy suddenly tightened around me. “A few more seconds,” she said, making me smile as I slowly slid my cock in and out of her a few more times.
Inch by inch, I pulled out, my cum lubricating her exit. I’d filled her to the brim, and I dragged a river of cum with me. Afterward, Chloe lay beneath me with a serene smile, her hand resting on her belly as if already protecting what might be growing there.
I rolled to her side. “We’ll have to wait a couple of days to know,” I said, stroking her hair.
She turned toward me, wrapping her arms around my neck in a tight embrace. “Thank you for being such a loving brother,” she whispered, then added with a shy smile, “and hopefully a father too.”
The weight of what we’d done settled over me as she dressed and left. I changed the sheets before my wife returned, but nothing could wash away the memory of my sister’s body joined with mine, my sex inside hers and the powerful climax as well.
*****
Two weeks later, I was alone at home after work. My wife had taken the kids to her sister’s again for a long weekend visit. I was sitting on the couch, mindlessly flipping through channels, when I heard a car pull into the driveway.
The front door burst open without a knock. Chloe rushed in, her face flushed and eyes wild with excitement. Before I could stand up properly, she threw herself at me, wrapping her arms around my neck in a fierce hug.
“I’m pregnant!” she exclaimed.
That’s when I noticed what she was clutching in her hand—a pregnancy test with two clear lines visible on the small display window.
I hugged her back. I had never felt so happy, seeing her smile after being so upset. I pressed my lips to hers, knowing she’d be a fantastic mother. “Congratulations, Chloe.”
“Thank you, Nathan. Thank you for everything,” she said, squeezing me harder in the hug.
The end.
