I woke up and stared at the ceiling, afraid to look in any direction for fear of seeing any evidence of the massive mistake I had made the night before. I tried to convince myself that it had all been some sort of fantastic wet dream, and that I would roll over and wrap my arm around my beautiful girlfriend Sabrina, and everything would be back to the way it was. This, however, was all in my head. I had done the most horrible thing, sleeping with my girlfriend’s sister. I wish that I had simply realized my mistake, woke her up, and kicked her out of the house before things went any further. I could have ended it all right then and there, cut this tense situation short and tried to pretend like everything was fine and that none of this had ever happened. That is not what I did.
As I stared up at the white painted ceiling of my bedroom, I felt Maddie’s slender hand crawl over my chest and rest around my neck. I took in a deep, anxious breath, and looked over at her. She was beautiful. So young a flawless, with clear, creamy skin that just begged to be touched. Her lips still had a hint of the dark lipstick that she had worn the night before, though much of it was worn off and imprinted over my own body. She looked up at me with piercing sapphire eyes, a look of seduction embedded into her very soul. Her striking blonde locks draped over her shoulders, messy and tangled from the previous night’s activities, and it framed her delicate face so perfectly that I couldn’t look away. Her skimpy outfit, while tantalizing in and of itself, couldn’t ever compare to the sight of Maddie’s body in its purest and most natural form. Her milky white skin was unblemished, and as she lay on her side, the gentle feminine curves of her nude body next to me made me shiver. Her flat stomach was toned with a slight indent of her strong abs, her thighs were smooth and velvety, and the way her free hand draped over her hip as she stared at me was flirty and sensual.
Her black and white striped and bejewelled fingernails tapped playfully against my chest, and she smiled at me with that crooked, devilish grin that made me twitch beneath my sheets.
“Finally awake, huh?” She groaned as if she were still sleepy. “I thought you would never wake up.”
Maddie leaned over, her long, slim fingers running through my hair as she pressed her pouty lips against mine. For a moment I didn’t think, I just felt her soft mouth on mine, her tongue slipped past my lips, and I felt her sigh sensuously against me.
“No.” I said calmly, shaking my head and pushing her away as gently as I could. “Last night was a mistake, the worst mistake I’ve ever made in my life. I love Sabrina, and I know you love your sister too. This is completely fucked up and I’m ending it right here.”
“Oh, you think you can resist all of this?” Maddie ran her finger tips over her curves and grinned. “You sure couldn’t stop yourself last night. And I don’t think you’ll be able to resist now either.”
Maddie bit her lower lip seductively, licking her lips and letting her fingers dance teasingly down my chest and stomach. I took in a deep breath and shook off the tingle that she sent down my spine. I grabbed her hand and shook my head again.
“I’m serious Mads. This stops now. You need to leave, go get dressed and find somewhere else to stay.” I felt confident, but soon that confidence was tested, as Maddie pulled the blanket down and exposed my half erect penis. She eyed my member hungrily, looking up at me again with those piercing eyes and that devilish smirk. She sat up next to me, teasing me by running her fingers up my bare thighs and tickling my taint.
Suddenly, she lowered her head and in one swift movement she took my entire length into her eager mouth. For a split second I was enthralled by the sensation of her skillful tongue and her soft lips gripping my rock hard shaft, but I knew that if this continued it could end my relationship.
“I said no!” I shouted at her through gritted teeth. I grabbed a chunk of her tangled blonde hair and pulled her off of me, pushing her away and sitting up against the headboard. “I am not doing this anymore! Once was a mistake, if it never happens again then we can put it behind us and pretend it never happened. We can both move on and get over all of this shit. If it happens twice then it’s a fucking affair Maddie!”
My hands were shaking and I felt a bead of sweat drip down my temple. I looked up at Maddie, who was now sitting next to me with her legs crossed. Her body was hard to resist, and she seemed to not be phased by my aggression.
“Hmmm,” she moaned, crawling onto her hands and knees, “an affair. That sounds so…dirty.”
She crept towards me, her round, yet perky breasts pushed forward by her upper arms as she moved closer. My breathing was laboured the closer she grew, and I was mesmerized by her hypnotic movements. Her perfectly round backside wagged back and forth behind her, and she lowered her head once again to take my throbbing erection in her mouth. This time, her hand crawled up my chest and pressed me back against the headboard. She dropped her head down until my tip hit the back of her throat and her lips were caressing my testicles.
I wanted to stop her, and I wanted to throw her from the bed and force her out of my apartment and put all of this insanity behind me. My body, however, didn’t react the way I wanted it to. There was something about her tongue swirling around my leaking tip that paralyzed me, her gorgeous face enveloping my manhood and the sultry moans that vibrated against me causing my entire body to relax and accept the pleasure. I reached out to once again force her away, but instead, my fingers tangled in her golden hair, and I groaned with satisfaction.
The thoughts of Sabrina started to fade away, and all I could focus on was the soft lips that were wrapped around my pulsating shaft. I began to breathe heavier, grunting and losing myself in the moment. Something deep inside me knew that it was wrong, but I suddenly lost control and gave in to my animalistic desires. My fingers wrapped around Maddie’s soft curls, and as she looked up at me, I pushed her head down hard. Her lips slipped down to the base of my cock, and I felt my engorged tip slide into her throat. She gagged slightly, and tried to pull away, but I was enjoying the intensity. I held her head down, and even forced my cock deeper into her throat as she choked and gasped for air. Her saliva was escaping and dripping down my shaft as her lips loosened their grip around my tool.
“Oooh yes!” I groaned, thrusting myself up into her mouth. I held her head there for what felt like minutes, feeling her gag and reflexively pull back against my clutches. The cold wet sensation of drool dripping down over my balls made me shiver, and her spit glazed my package as she choked and moaned against me.
I finally released her, giving her some hair as she pulled back and gasped. A long string of saliva connected her lips to the tip of my cock, and drool hung down from her chin and she swallowed hard. She didn’t hesitate, and immediately took me into her mouth again. She was so enthusiastic to taste me, and her sopping wet mouth gave me such incredible pleasure that I was soon near orgasm.
“Oh, shit! Mads, I’m going to fucking cum in your dirty little mouth!” I could barely get the words out before I felt the pleasure building inside me. My balls tightened, and the wet globs of saliva that coated my cock and balls sent me over the edge. “Fuck, yes! There it is, take that fuckin’ load Maddie!”
There was something naughty and filthy about cumming in my sister in law’s mouth that gave me one of the most intense and exhilarating orgasms of my life. The look in her eyes when my thick cream spurt into the inside of her mouth made me shudder, and the explosiveness of my climax caused a mixture of saliva and cum to gush around my cock and smear across her face. I grunted loudly, thrusting up into her mouth and coating her tongue and throat with my milky gift. Her eyes rolled back in her head as she hungrily swallowed every drop that I offered her. When my orgasm reached its peak, Maddie slowly lifted her head from my member and looked up at me with a satisfied grin.
“I knew you wanted more. You just can’t resist my slutty little mouth, can you?” Maddie’s face was a vision of heaven. Her mouth was smeared with spit and cum, the excess mixture dripping in globs from her chin and onto her ample breasts. I looked down at my cock, glazed with a thick coating of Maddie’s saliva.
“You’re right, I can’t. I’m going to have you exactly how I want you.” I gave her a look of pure, wild lust, and lunged towards her. I tackled her, pinning her down on the bed as she giggled playfully.
“Mmm, I knew I could get you to forget all about my sister.” Maddie teased with a knowing grin. “You know you love my mouth, I can do things to you that you know she never could and never will. You’ve always wanted my soft lips wrapped around your dick and my tits in your face.”
She was right. A part of me, I think, always wanted to touch her young body and feel her tight pussy around my cock. She was so gorgeous, and seemed so innocent, and there was something intoxicating about having her all to myself while my girlfriend had no idea.
“You know, I can do other dirty things to you that my prude of a sister would never even think to do. You can do anything to me, and I do mean anything.” Maddie reached down and started stroking my still erect cock. Her saliva was wet and cold on my shaft as she jerked faster and faster while I looked down at her perky round tits bouncing up and down just for me. “My pussy is tighter, too. I’m still so young and taut, ready for a nice big dick like yours to slide in and stretch me out.”
I listened to her speak, the spit still glistening on her chin as it dripped down her neck. Before I knew what was happening, she had wrapped her free hand around my waist and was pulling me into her. My cock was slick with saliva, and it easily slid into her smooth, tight pussy. I let out a soft groan, my drool covered manhood lubricated so perfectly as I penetrated her young, clenching hole. Soon I was filling her completely, and she softly whimpered and smiled up at me with a yearning expression.
I began to thrust into her with animalistic passion and intensity. She moaned out loud, her bouncing mounds hypnotising me as I stared down at her with unabashed exaltation. I was captivated by her beautiful body, and I ravaged her without hesitation. She was mine, and I didn’t care anymore how wrong it was. It felt good to be bad, and every time she moaned with pleasure she made me want her even more.
“Oh fuck, you-you’re so fucking tight. God I love this pussy Maddie, you’re the tightest little cunt I’ve ever been in and I love it!” My heart was beating fast, the velvety hole that enveloped me was like being wrapped in pure bliss. “Holy shit, I’ve never felt as good as when I’m inside you Maddie.”
It was the truth. Her body was unlike any woman I had been with, including my girlfriend. Even though they were sisters, Sabrina and Maddie had clear differences, and Maddie was so much younger and more taut and toned than her sister. Her body was intoxicatingly firm, with toned abs and a petit yet round backside that I couldn’t keep my hands off of. Her breasts were the perfect size, and I traced her stiff nipples with my tongue while her angelic voice echoed throughout the bedroom. Her melodical moans were smooth and deep, pure passion seeping from her lips as I penetrated her welcoming depths.
“Oh my God!” She cried out, her long fingernails digging into my shoulders. “God, you’re so fucking big baby. You fill me up so damn good, I love how you fuck me bareback and hit my g-spot so perfectly! Holy fuck, I think I’m already about to cum for you, mmm don’t you dare stop!”
Hearing her impassioned groans and whimpers made me tingle. Her back arched, her breasts heaving upward into my mouth, and I sucked on her nipples vigorously as my thrusts became deeper and faster. She clawed my back, dragging her nails over my tender flesh and wrapping her legs around my waist. She began to gyrate uncontrollably against me, her moans turning to unbridaled screams of pleasure.
“Yes, yes! Fuck me like you fuck my sister! Do things to me that you won’t do with her! Fuuck I’m cumming for you!” With that, Maddie let out a cacophony of ecstatic noises that filled my ears and nearly sent me into convulsions. Her body shook, quivering with delight as she released. Her voice was muffled as she buried her face into my chest, slightly biting at my pectorals as she thrust her pelvis up into me. I could feel her juices flowing down my balls and thighs, a powerful spray of feminine fluids drenching us both in her sweet, sensuous liquid. She was squirting.
“Oh, holy fuck Maddie! My God, you are such a fucking dirty little girl!” I looked down at her, her face twisted in the sweet release of orgasm, and I had never wanted her more.
I watched her bite her lower lip as she looked up at me with complete satisfaction, and I enjoyed the sight of her enjoying the pleasure I had given her. She ran her hands over her body, cupping her bouncing breasts and rubbing her nipples as I continued to use her tight, young body for my own gratification. I didn’t slow down, not even for a moment to let her pussy rest and recover from her intense climax. I penetrated her clenching chasm over and over, staring down at the beautiful, youthful creature that was giving herself so completely to me.
The slavia still clung to her chin and neck, and the memory of her mouth around my shaft sent a shiver down my spine. She was so unlike Sabrina, who hadn’t blown me for months. Maddie loved it, I could tell how eager she was to taste me again, and I was just as eager to feel her mouth around my swollen member. I thrust one last time, deep and hard into her aching pussy, and pulled my leaking tool from her inviting womb. An expression of disappointment passed over her face, until I crept up in the bed, straddling her shoulders, and she realized what it was that I was about to do. I positioned the tip of my cock into her mouth, letting her enthusiastically suck on my dripping knob with a sultry twinkle in her eye. It didn’t take long before I lost control, and leaned forward over her, clutching the bedframe with white knuckles.
“Oh fuck, Mads, I need to fuck fhat pretty face of yours!” And I did. I humped her face, fucking her beautiful mouth like she was nothing but a toy for me to use however I liked. I thrust into her mouth, feeling the back of her throat against the oozing tip of my manhood. She gagged slightly each time I penetrated her throat, but she clung to me, her hands grasping at my hips and ass and pulling me deeper into her throat. I could feel her lips closing tight around my shaft, her tongue expertly caressing my frenulum even as I forced myself into her gag reflex. I looked down, panting, to see her eyes rolled back once again in the throes of ecstasy. Drool and precum flying across the bed and splattering over her silky skin.
“Holy shit, you look so hot with your mouth full.” I grunted, never slowing or stopping to give her a chance to breathe. “Holy fucking shit, girl. Your sister would never do this. Ooh, God! You…you really are so much fucking better than she is, Maddie!” She was my toy, my plaything, my side piece. I continued to hump her face, feeling the cold, damp saliva dripping down my balls as they landed with a wet splat against her chin with every thrust. Her face was glazed with a thick coating of spit, my thighs still moist with feminine fluids with which she had gifted me. Her bouncing mounds were splattered with saliva, precum, and her own delicious juices, and I couldn’t help but stare at her messy face as she greedily took my entire length down her throat.
Maddie couldn’t speak, her mouth and throat were filled with my meaty offering, but I could tell she was loving every second of what I was doing to her. The look in her eyes was unmistakable, she was a hungry little slut, and all she wanted, was me.
“Fuck, fuck, fuck! I want to cum inside your dirty little slutty pussy!” I cried out as I felt my balls begin to tighten, and the familiar sensation of a building orgasm reaching ever closer to its climactic peak. “You’re going to be my filthy cum dumpster Mads!”
I slid backward, pulling my member from her mouth. As it landed with a wet splat into her drool coated chest, I shuffled down until I was once again between her firm, smooth thighs. Without hesitation or warning, I slid my dripping member into her welcoming pussy, the thick coating of saliva and precum lubricating my way into her clenching chasm. She let out a soft, gasping moan as I penetrated her once more, her satisfied smile glistening with spit. I began to pump in and out, grabbing her glorious breasts with my one free hand. Just as I felt my impending climax reach its full potential, Maddie pushed me over the edge like no other woman could have.
“This dirty little pussy is all yours. You can have me whenever you want, and use me as your cum slut whenever my prude sister deprives you. Now cum nice and deep in this pussy and fucking make me your whore!” Her voice was soft and innocent, with just the right hint of brattiness that sent me into convulsions.
“Ooh you are my fucking whore! Cum for me, Maddie!” Her hand reached down quickly to massage her swollen clitoris, my engorged tip reaching her sensitive g-spot, and just as I began to spurt, Maddie erupted in a shrill cry of pleasure.
I felt her juices flow around my granite shaft once again, and my member plunged deep inside her, filling her with my warm, gooey cream. I shuttered, groaning and sputtering nonsense as I released into my young, perfect sister in law. Her orgasming cunt was clenching and squeezing around my shaft, coaxing every drop of semen from my body as she writhed beneath me in unbridled ecstasy. I could feel her warm, feminine ejaculate pooling on the bed around my knees, spraying over my legs and dripping down our bodies like a waterfall.
Her mouth was wide in a silent scream, strings of drool and precum connecting her supple lips. I couldn’t stop myself from hammering deep and hard into her velvety hole, my pelvis uncontrollably thrusting over and over until I was sure I was completely empty. I finally stopped, letting my cock soften inside of her gushing womb. I just stared at her for a moment, realizing that I couldn’t stop myself from taking her whenever I wanted. She had me, and I couldn’t resist the temptation of her young, tantalizing form.
I slowly pulled back, my manhood sliding out of her with a splat onto the soaked mattress. I watched as her gaping chasm gushed a mixture of fluids all over herself and the bed. My cum oozing from her beautiful cavern, glazing her firm ass cheeks and leaving strings of sticky semen all over her thighs. She was spectacular.
I had cum inside my sister in law. I had fucked her bareback in the bed that I shared with Sabrina, and her own sister was now laying with her legs spread, rubbing her tender clit as she gushed my thick, milky load out onto the mattress that she and I had purchased together. I should have felt guilt, shame, fear, worry, but I felt none of those things. I felt satisfied. I felt dirty and wrong, but only in the most gratifying way. I watched Maddie sit up, her legs still spread as she licked her cum covered fingers. She crawled onto her hands and knees, pushing me back against the headboard and cuddling up under my arm.
We both laid there a while, I don’t even know how long. We breathed and panted and gasped for air, letting our bodies settle into one another. I couldn’t help but to look at Maddie as she lay next to me. Her perfect curves, her toned, flat stomach, her smooth legs, her golden hair tangled and flowing down her shoulders. I knew I would have her again, I wouldn’t bother trying to resist.
“I bet I know what it is you’re thinking right now.” Maddie teased, looking up at me with a sultry grin. “I have you now. And I’m going to use that cock whenever I want. You’re going to do whatever I say from now on, because you can’t get enough of this pussy. If you want to keep fucking me behind my sisters back, you’ll be a good boy, won’t you?” Her victorious smirk made me shutter, and I knew that she was right.
I nodded in agreement, not even attempting to resist. I knew in that moment that I would do anything to taste her juices again, to smell the scent of her hair as I penetrated her. I would give anything to sneak away for even a minute of time inside her tight, young cunt, and I’d practically kill to cum inside her again. She knew she was in complete control of me and I was perfectly willing to give up that control, if it meant I could have her again and again.
“Trust me, you aren’t going to regret this, I’m so much better than my sister. And, this is definitely going to continue even after she’s back.” Maddie sighed, wrapping her arm around my waist and laying her head on my chest.
I didn’t know how we would continue our affair once Sabrina was back home, all I knew was that I would find a way.

Nice. Made me “shutter”, too.
