I couldn’t help hearing the noise coming from my sister’s room. We had moved in together in a small apartment attached to the back of a house in Florida so we could attend the local community college. 

I knocked gently on the door. I knew from what I heard what was probably going on. “Hey. Sarah. You okay in there?” I asked laughing to myself. Her name was Sarah Kate but now she wanted to go by just Sarah. She got tired of everyone butchering her name and had given in. 

“I’m fine!” she said, rather sweetly with a yawn, trying to pretend as though she was just waking up. 

“Come on out. I’m making breakfast.”

She unlocked her door and came out in his nightshirt. 

She ate breakfast at the small dining table we had in the kitchen, her leg up on the chair, facing me. I could see her pussy through the thin cotton of her panties. Finally, she finished, looked at me strangely, then walked back to her room to dress. I wanted so bad to be in there with her at that moment, watching her undress. I had always had these feelings, I knew, but had worked through them. Now, something was different.

That night, after we had gone to bed, I couldn’t sleep. The image of her pussy through her panties was stuck in my head. 

I touched my hard cock and pictured Sarah Kate in her nightshirt. I pictured my hand running up her leg under the shirt. I pictured her lips. I pictured them on my cock, the tingle of my sister’s warm soft lips pulling my cock into her mouth. I pictured her breasts, small and tight, under my fingers, my hand in her cunt, my fingers damp, my cock twitching, her breathing, panting, sweet cunt rippling. I came. I opened my eyes to see the cum flow from my cock with the memory of my sweet sister in my mind and saw a movement in the doorway. My orgasm froze and I grabbed a sheet to pull it over me. I sat there for a moment heart fluttering wondering if she had seen me. Excited somehow.

“Jeez, John,” she said. “Maybe you should close your door. I’ve never seen that before.” The last sentence was quiet, with a little catch in her high voice. She was still out of sight around the corner. 

“Maybe you shouldn’t sneak up on me!” I said. And I regretted it. 

The next day nothing much happened. It was a long one. I got off work late and came home to the TV on. 

Sarah Kate had fallen asleep on my bed, watching TV again. Her nightie was pulled down just over her soft mound, but I could see the white cotton panties she wore. I started trembling hard when I saw it. It was like a chill settled in the room and my whole body shook.

Carefully, I turned down the TV. I sat on the edge of the bed, watching her face, making sure her eyes were closed. She breathed gently. I slowly moved my head down to where my nose was almost touching her mound. I could smell my little sister’s sex. I trembled again and thought I heard a catch in her breathing.

I pulled back slowly and looked up to see a slight glint through her eyelids. I freaked out a bit thinking she was awake and watching me. Then she sighed, and squirmed a bit, but didn’t move her hips at all, just rocked her shoulders a bit more. I thought for a minute that maybe she even pulled her nightie up a bit, but saw that she had raised her arm over her head to put it on the pillow. I could see her nipples sharp through the shirt. They were tense. Was she breathing harder?

I leaned back down to her mound. I slowly pushed my tongue between my clenched teeth, worried I might bite it I was trembling so hard. I could smell her sex. My tongue touched the warm cotton. I tasted her through it. Sweet and salty. I was stiff as a board. I lifted up and grabbed my cock. Looking at her mound, then her face, then her nipples, then her mound, I stroked my engorged cock and rasping out quiet breaths shot a stream of cum over her legs and onto the bed. She murmured and sighed, then rolled over, while I stood still as I could with my cock in my hands.

I went into the bathroom and cleaned up. Trembling. When I came out, she was in her room with the door closed. I crept into bed and turned the light out, worried she might realize something was dripping down her leg. 

I couldn’t sleep. I thought about her mound and thought some of my cum might have landed on it. What if? I couldn’t sleep thinking about it. My cock stiffened again. 

I heard a noise as her door opened and a thin light flowed into the hallway. She went into the bathroom and I heard the tap. The light streamed across my bed and I saw proudly that the sheets were tented. I didn’t care. I wanted her to see. She came out and paused for a moment. I watched her through slitted eyes. Then she came over to my bed. I trembled. I thought she might say something to me about the cum on her mound. Her soft mound. My cock throbbed. 

“John?” she whispered. I couldn’t see her face through the strawberry blond hair and backlighting. 

“Mmm.” I feigned. 

“I can’t sleep.”

She crawled into bed with me and I jumped when she touched me. “I can’t sleep,” she whispered, her mouth close to my ear, her breath on my cheek, her breasts and warm body pressed against me, “with my brother’s cum on my pussy.” Then she kissed my ear. I moaned. My cock throbbed. “Why isn’t my brother’s cum in my pussy? Why isn’t he fucking his little sister, so warm and ready?” 

I swung my arm around her and pulled her close into a deep and long kiss. I tasted her. My sister’s mouth on mine. My hand moved over her body, down her shirt, down her small breasts. When I grazed her nipple, she gasped and moaned with pleasure. 

My hand went slowly up her leg as our lips met again. A powerful incestuous urge sprang up in us. I realized I had wanted this for a long time. I pulled the fabric of her panties to the side and slipped my fingers into my sister’s pussy. It was hot and wet.

She moaned through her teeth. Pulling her head back violently. “Oh, John. Brother. Yes! Big brother,” she moaned in my ear again and again as my fingers worked over the inside of her pussy. “Fuck me, John! Fill me with your cum!” she said, pulling her head up and putting her hand in my hair, looking me in the eye intensely. “Fuck your little sister! Fuck me! I want you!” I paused. She grabbed me harder by the head. “I want to see you cum this time. I want to taste you this time. I want to taste my brother in my mouth. Cum in me!”

“Oh, Sarah Kate!” I moaned in ecstasy. I had no idea I had wanted her so bad. My cock was a steel rod. 

I kissed Sarah Kate’s lips, mouth, feeling our spit mingle. Then slowly I pushed my steel rod of a cock into her vagina. I pushed until the tip met her cervix. “Oh my god, Brother! John! My. Uh. Brother! Uuh.” She panted, gasping. I pumped a few times and exploded against her cervix, shooting stream after stream of cum into my little sister’s body as we stared at each other. But my orgasm kept coming as I pumped into her. “John! Oh god, fuck me! Fuck your little sister!! Fuuuck meeeee!” She came hard.

I kept pumping into her, my orgasm building slowly again. She came again and again, and I pumped harder then slowly after every gasp, as I rammed my sperm deeper into her womb. I built up again, my balls pushing towards another ejaculation. “I want to taste you, John! Come on my face!” I pulled out and put my cock on her lips before I thought I was ready. But just seeing her face made me cum suddenly. She leaned back and a stream of my semen, her brother’s cum, poured over her lips and her teeth. She drank it. “My god, brother. My brother. I love it! I love your cum!”

We finally fell apart, spent for the moment. But my sister Sarah Kate and I made love again that night. And we have made love, soft and passionate love, every night since then.
