"Mmmm yes, you are my little cum slut aren't you?" she declared wickedly. "Tell me you love being my little slut."
"I love being your little slut Sarah."
"Say it in your slutty girl voice. Say 'Oh Sarah, I love being your dirty little slutgirl."
I switched to my submissive girl voice, pitching my voice up and adding a sensual, girly affectation. "Oh Sarah, I love being your dirty little slutgirl."
"Good giiiiirl. You're my slutty little girltoy aren't you?"
I looked into her eyes and nodded submissively.
"Who's your favorite little sister, slutgirl?"
"You're my favorite little sister, Sarah."
"Good girl," she said, squeezing my cheeks with her hand, splaying out my lips and preventing me from responding again. "You're such a good big brother. God, I'm so wet."
Sarah lowered herself back onto my face, this time placing her pussy right into my mouth. I shoved my tongue inside her and started lapping up her cum as she convulsed, her thighs flexing and relaxing erratically on my head. We stayed in this position for a good while, and she put her hands to good use. She grabbed my hair, pulling on it as she convulsed and twitched on my face. She bent back to grab my arms, pinning me to the ground as she rode my face in a rhythmic circular motion. Her convulsions became stronger and more frequent, and eventually she came, screaming as her juices gushed into my mouth and all over my face.
Too spent to get up, Sarah let herself fall backwards onto me, her head coming to rest right over top of the rock hard bulge trying to free itself from my shorts. Feeling my crotch with the back of her head, she smiled and purred, rubbing her head back and forth on my pants before languidly reaching over her shoulder and slipping her hand under the waistline of my shorts. Once inside my boxer briefs, she wrapped her hand around my dick and gave it a hard squeeze, causing both of us to moan together and my dick to throb hard.
Sarah's pussy was still in full view of my face, right under my chin, her pelvis resting on my chest. I tilted my head to look down and noticed that her pussy and my dick were both throbbing in sync, which made me even harder. Sometimes it felt like Sarah and I were connected psychically, like I could feel what she felt and she could feel what I felt. In moments like these it was as if the boundaries of flesh were dissolved and we were one singular organism. Her pleasure was mine and mine was hers, to the point where there was no "mine" or "hers", just raw intimacy. I've made some good friends and even had a few serious relationships since those days, but nothing has ever come close to that. But how could it? Sarah and I have the same parents, share the same genes, grew in the same womb. We were raised together and spent most of our formative years together, apart by only a few years. We went through puberty together and discovered our sexuality together. Perhaps that's why intimacy between siblings is taboo. After what we've had together, could either of us ever be satisfied with someone else?
As Sarah continued to massage my dick, I noticed that her feet were behind my head now, one on each side, and reached my hands up to hook the tops of her thigh-highs, pulling them down her thighs. She lifted her legs to accommodate me, and I slid her socks all the way down each leg, pulling them off both of her feet at the same time and watching the damp fabric peel off her sweaty skin. Once they were removed she lifted up her legs and bent her knees, dangling her feet over my chest.
I looked up in admiration at Sarah's creamy, irresistible feet. Both of us have similar skin color — similar to our Japanese father's Asian skin tones, but lighter and with a little pink in our faces, hands, and feet. She looks more Asian than I did, her feet smooth and elegant, but larger and fuller than most Asian woman's feet—she wears a 7½ or 8, quite large for someone her size—probably from our Czech mother, along with her long, curved toes that look like they could pick stuff up.
My intentions were clear at this point. Sarah took the initiative and placed both feet directly onto my face, covering me completely. I inhaled deeply and my eyes rolled back into my head as the smell of old sweat, vinegar and Sarah's natural odor penetrated my senses. She pressed her feet firmly against me, from her heels to her toes, imbuing my face with her scent as I continued sniffing. I let out an involuntary moan, my mouth dropping open, as she dragged her left foot down my face. She slid her foot over my nose and then my upper lip, whereupon she abruptly tilted her foot forward while flexing her toes into my open mouth. Her toes entered my mouth so suddenly that I, on instinct, tried to shut my mouth, which only pulled her foot deeper past my teeth. Her foot halfway in my mouth now, she curled her toes downward over my bottom teeth and pulled down, dragging my mouth open again as her foot slid back out, at which point her toes caught my bottom lip, pulling it down over my chin and then slowly releasing it one toe at a time as her foot slid off my face. I shuddered.
As soon as her left foot left my lips, her right came down and wrapped its toes around my nose, while her left foot resumed caressing my face. I was paralyzed with arousal at this point, and the only thing I felt capable of doing was to inhale her sour foot stench, deeply. It was heaven and hell all wrapped up as one, the sourness with the sweetness of my sister's natural body odor, the pure pleasure of sexual abandon with the wrongness of knowing she was my sister. My mouth hung limp, my face a raw mask of animal pleasure as Sarah continued to squeeze my cock and rub her feet on my face.
You would think I would be used to this by now, that it would have lost some of its savor, but my little sister has always had an uncanny ability to get me very hard, very fast. Even when we were young and inexperienced, before we had ever talked about our fetishes and fantasies, she somehow knew exactly what to do. I remember the first time she caught me smelling her feet...
