The sight I saw when I opened my eyes again will be burned into my memory forever. Naomi was on her knees, her head on the ground, her ass high in the air. The man, who I had forgotten even existed until that moment, was standing over her, his massive figure now completely nude. Sandy hair covered his thick muscular legs and ass. His big balls hung heavy between his legs and I could see his cock dripping thick, crystal clear precum as he held it by the shaft, pointing it downward so that it hovered menacingly over my sister’s wet holes as he squatted above her.
I felt my body shiver as I looked at this scene, drinking it in. It was like I was inside a porn movie, watching it in 4D… except this wasn’t a porn movie, it was my sister’s bedroom and I had just done the unholiest of unholies with my own flesh and blood. Time seemed to freeze as I looked at her perfectly manicured, completely hairless gaping pink pussy, framed with dark beefy curtains of flesh and crowned with a cute pastel clit. Without thinking I pushed my hand down into my panties to start playing with myself again, but as I did, I felt my fingers brush through the thick black bush of my own unkempt pubes. A wave of self consciousness washed over me as I realized that even though she was older that me, she had the pussy of a little girl, while mine was that of a feral woman living in the wild. I looked down at myself, pulling my panties aside. Thick black hair matted down with cum obscured my clit and lips. I had the sudden urge to get dressed and run out of the room as fast as possible.
I scurried to my knees and reached out to grab my jeans, but when I did, my sister reached out and put her hand on mine. Our eyes met and she whispered something to me that I didn’t catch. I opened my mouth to speak, but no words came out. I looked up and saw him looking at me, his face a wordless command that I couldn’t disobey. I crawled meekly to him, and he took my face in his large hands. My eyes were locked on his, but I was painfully aware of his big cock throbbing just inches from my face and it was horribly distracting.
“Which hole?” he asked me.
I looked at his pulsating cock, shaft covered in veins as thick as udon noodles, bulbous purple head glistening wetly.
“You choose,” he said patiently.
I turned to look at my sister’s holes, my eyes wide. This is my sister. I had just had lesbian sex with my sister. And now I was in a ménage à trois with my sister. I had crossed a line that I could never come back from. Incest. I was doing it. I liked it. And I wanted more. I put my hands on my sister’s ass, rubbing her soft skin down to the backs of her thighs then back up again, admiring her body and watching her react to my touch. When my hands came back up to her cheeks, I spread them a bit and her wet asshole puckered. I giggled as I watched it, then looked up at the man and nodded.
“Good girl,” he said. “Now take it in your hand. Put it in.”
I reached out, grabbing the man’s cock like it was a python ready to strike. The thing was thick and hot, it felt like it was burning my hand when I touched it. I squeezed hard, pulling him close, and he let out a satisfied grunt as it throbbed in my hand, a sticky clear ribbon of precum running down his shaft and over my hand, then dripping onto my sister’s ass. I liked his reaction, so I tugged again, harder this time, jerking on his cock with my one hand as I rubbed his precum into my sister’s asshole with the other.
I’d never really enjoyed sucking dick before but I guess was caught up in the moment, because I started licking up and down his shaft, moving from down by his balls all the way up to the tip of his cock, then taking the tip of his cock in my mouth and biting around his cockhead as it throbbed in my mouth.
After teasing him, I turned and spit in my sister’s asshole. Her little hole winked at me, swallowing my spit, and then closed up again. I couldn’t help but giggle some more, it was so cute. I put my mouth on her butt hole, kissing it softly and whispering to it, “kiss me.” She obliged, kissing my lips with her hole. I kissed and licked her, making out with her asshole. When her hole would wink, I’d push my tongue into her, licking into her butt hole so that she would close around my tongue and suck on it with her asshole. The sweet, mildly spicy smell of her butt hole was intoxicating, and as it mixed with the pungent, vulgar stink of her pussy it made me feel dizzy. I spread her ass open and put my finger in her, feeling her grip around my knuckle. It was so tight. I had no idea how she was going to take that big cock.
As if reading my mind, I felt him stroke my hair, then slide his cock between Naomi’s ass cheeks. I kissed at his shaft as he moved his dick between her wet cheeks, like an obscenely large hot dog sitting in a comically small bun. I’d always thought Naomi had a pretty big ass – like I’d been jealous of how nice her ass was – but this guy made her look absolutely tiny. I watched him rub his cock back and forth across her asshole for a bit, then, as he pulled back, and reached out and pressed my hand against his cockhead, pushing against her tiny hole. She gave out a soft moan as the big head of his cock stretched her, but to my absolute shock, after a few tense seconds, he was inside her. I couldn’t believe she was able to take that thing up her ass like that and I felt my face get hot as I tried to imagine taking something like that up my own ass. No way. After a couple dozen slow exploratory thrusts, he wasted no time getting to work on my sister’s hole, pumping his thick shaft balls deep into her asshole with each wild thrust of his hips.
I played with myself as the hot smell of raw, spontaneous anal sex filed the room. From time to time he would pull out, his cock glistening with ass cum and sweat, and admire my sister’s gaping hole, before plunging back into her. Every time he would pull out, I’d feel the longing desire to suck him off off and taste my sister’s insides, but I was too shy and too embarrassed to do it. I’d never done anal before, even though it was something that I’d fantasized about so many times. But watching him destroy my sister’s asshole and masturbating finally got the better of whatever inhibitions I had left and I reached down, pushing my middle finger into my own asshole. I rubbed on my clit as a fingered myself, imagining what my sister was feeling. Just before I was about to come, I looked over and saw that she was watching me, her hands stretched down between her legs, fiddling with her own clit as he used her ass. I pulled at my panties, the wet lacy fabric ripping away, then turned toward her, spreading myself so she could watch me finger my ass and abuse my clit. I closed my eyes, my head pressed back against the bed as my orgasm built, my mouth gaping in a soundless moan, when I suddenly felt it, hot and muddy, against my open lips. Without hesitation, I closed my mouth around his shaft, slurping sloppily on his dirty cock as my tongue cleaned his cockhead. I came hard as the smell and taste of my sister filled my head, my asshole biting down hard on my finger, my body shuddering violently. I sucked on that big cock like a hungry baby, still grinding on my clit, desperate to come again and again. I’d never felt so fucking horny in my entire life.
