Lust for My Sister's Husband

The Chennai sun was merciless, much hotter than a typical afternoon as I traveled down Anna Nagar to my destination. The auto driver navigated through a tangle of interconnected streets until he eventually brought the three-wheeler to a halt in front of a cream-colored, two-storey independent house at my command.

I hopped out, my oversized sunglasses still perched on my face to protect my eyes from the worst of the glaring sun rays. I wiped my sweaty forehead with a kerchief, pulled my heavy trolley bag from the back seat, and dropped it onto the paved sidewalk.

I pulled out a five-hundred rupee note from my purse and handed it to him, then waited to collect my change. He was fumbling with his cash pouch, moving far too slowly for my liking, so I let out an exasperated sigh. "Anna, please be a bit fast. This sun is literally burning my skin."

He looked up at me with a toothy grin. "Two minutes, madam. Don't get angry, I am just finding exact change for you. You know how it is since they stopped the two-thousand rupee notes, everybody is fighting for hundred rupee notes."

I finally took the three hundred rupees he handed me, stuffed it in my purse, and turned around with my luggage to face the imposing black gate of the house. "Aiyyo! This madam!" I heard the auto driver call out as I walked away. "You look very beautiful, ma."

I ignored him, shaking my head. "Just go do your duty, Anna. Go earn some money to give your wife tonight instead of staring at me." He let out a hearty laugh, muttered something in Tamil, and sped off down the street.

I knocked on the heavy metal gate first, just in case someone was wandering around the compound. When there was no response, I reached out and pressed the doorbell situated right next to the pedestrian entrance. Less than a minute later, the gate made a loud clanking sound and was pulled inward to reveal my older sister, Divya. She looked utterly surprised to see me but instantly recovered her composure and moved aside so I could wheel my bag in.

"Archana! Why didn't you tell me you were coming today? I would have come to pick you up from the airport, babe," she chided me affectionately as we walked up the driveway.

I laughed at her scolding tone and assured her it was completely fine. We walked into the cool, air-conditioned house together. She insisted on taking my heavy trolley bag, dragging it upstairs to the guest bedroom I always stayed in. I headed straight for the kitchen, yanking open the double-door fridge in desperate search of something sweet and icy. I settled for a large bottle of chilled Frooti, chugged nearly half of the mango juice in one breath, and let out a long, passionate sigh of relief as the cold liquid traveled down my parched throat to settle in my belly.

"That sun out there is brutal, isn't it?" Divya asked, walking in and leaning against the granite kitchen counter opposite me.

"You have no idea. I thought I was going to melt."

I stood there, just taking deep, calming breaths, waiting for my body temperature to return to equilibrium, when I noticed Divya watching me. She had her hands placed casually on her hips, her posture pushing her chest outward. And that was when I noticed the stark difference.

"Aiyyo, Divya, what is Karthik feeding you these days? Why are your breasts getting so big?" I teased, boldly reaching out to grab her boobs through her soft cotton kurti, playfully weighing them in my hands. They had definitely gotten much fuller and heavier.

My sister and I had always been incredibly open about our bodies and our sex lives, so I knew that, physically, we could have passed for twins. Not anymore. While my ass was still noticeably thicker and rounder than hers, her breasts were now easily a full cup size larger than mine. She swatted my hands away, her cheeks flushing a deep crimson.

"My husband just takes really good care of me, that's all," she replied with a shy smile.

I knew exactly what that meant. Based on the unfiltered stories she had shared with me in the past, Karthik had an absolute obsession with her breasts. Just a few months ago, after polishing off three glasses of wine during her visit to my place in Bangalore, she had launched into a steamy, graphic narration of her husband's insatiable sexual appetite for her chest. Sucking, licking, titty-fucking, and painting them with his cum after sex were apparently his absolute favorite pastimes.

I had gotten so incredibly turned on that night just visualizing the two of them together, I had spent over an hour aggressively riding my favorite dildo until I finally calmed down enough to fall asleep.

When I first met Karthik, I hadn't even realized he was dating my sister. He was so calm, intelligent, and intensely focused. But he possessed one of those devastating smirks that immediately made your mind wander to hot, naughty things, even though his everyday demeanor made him seem like a total gentleman. I had secretly developed a massive crush on him from day one, but I never let it show.

They had tied the knot in a grand Chennai wedding less than a year after that first meeting, and I forcefully let the attraction go. If there was one thing I was constantly reminded of whenever I visited them, it was how deeply and genuinely he loved her.

We continued chatting for a long time before shifting to the plush sofas in the living room. I asked for updates on her life and her voluntary work for a local women's NGO, and she eagerly asked about my career. I am a senior software developer at a top IT firm in OMR. My development team and I had been building a complex enterprise software for a multinational client, and I had a massive final presentation scheduled for this week. Hence, my official trip to Chennai.

We spent the remainder of the sunny afternoon gossiping about mutual friends, extended family drama, and random internet trends. Eventually, the conversation inevitably steered toward my non-existent sex life, much to my annoyance. I hadn't been actively seeing anyone for the past three months, making my romantic life my absolute least favorite topic to discuss. And it certainly wasn't due to a lack of eager suitors—God knew my DMs were overflowing. The fundamental problem was that I always managed to find a glaring flaw to instantly discredit each one of them. Either they were far too clingy, entirely too gentle in bed, suspiciously nice, or they just didn't fuck me anywhere near as hard and rough as I craved.

In all honesty, I hadn't been feeling particularly aroused by the men in my immediate circle lately, so I had stubbornly placed myself on a self-imposed vow of celibacy.

Later that evening, we enjoyed a heavy, delicious dinner of hot dosas and rich, spicy Chettinad chicken curry, my absolute favorite. Exhausted from the day, Divya went to bed quite early. I remained curled up on the living room couch, my laptop resting on my thighs as I tweaked some code and finalized my presentation slides.

A few minutes past ten o'clock, the heavy main door clicked loudly and swung open. Karthik dragged himself in, a sleek leather laptop bag in one hand, looking completely drained and utterly exhausted.

"Hey, babe," he called out softly into the quiet house. "Sorry I'm so late, the server migration took much longer than I anticipated."

I looked up from my glowing laptop screen, catching his eye from the couch. He stopped in his tracks, his tired face immediately breaking into a warm, surprised smile.

"Archana!" he exclaimed, genuine surprise in his tone. "Wow, when did you get here?"

"Just this afternoon," I replied, setting my laptop aside and walking over to him. "Come here and give me a hug, ya."

He let out a low, husky chuckle, and for some inexplicable reason, I found the sound incredibly sexy. I stepped right into his open arms after he dropped his heavy bag to the floor, wrapping my arms tightly around his broad shoulders as he hugged me back. He smelled intensely masculine—a raw mix of male sweat, faint cologne, and the distinct scent of long office hours.

"How was your flight down?" he murmured against my hair before pulling back slightly.

"Smooth enough. But you look absolutely dead. Your wife is already upstairs sleeping. Do you want me to heat up your dinner?"

He looked at me with such gratitude, I thought he might actually kiss me in thanks. "Yes, please, God. I honestly don't think my legs can carry me to the kitchen and back before I collapse, but I really don't want to trouble you."

"Don't be silly. Go sit at the table."

I headed into the kitchen, popped the already plated dinner Divya had set aside into the microwave, and brought the steaming food to the glass dining table where Karthik was slumped, mindlessly scrolling through his smartphone.

I settled back onto the sofa, leaving him to devour his meal in comfortable silence. He polished off the food much faster than I expected. He looked slightly rejuvenated, but the dark circles under his eyes remained.

"So, how long do we have the pleasure of your company this time?" he asked, wandering over and collapsing onto the couch right beside me.

"A good while," I replied, not looking away from my screen. "Three full months. Major new deployment phase."

He hummed in acknowledgment and just sat back, quietly watching me type lines of code for a while before his head lolled back and he drifted off into a deep sleep right there in the living room.

I kept working diligently until about 3 AM, occasionally glancing over as Karthik tossed and turned uncomfortably on the leather cushions. Finally, I shut my laptop, stretched my stiff limbs, and stood up to gently tap his shoulder.

"Hey. Karthik. Wake up. Time to get you upstairs to your comfortable bed with your wife."

He barely registered the touch, so I gently patted his cheek, trying to be firm without actually slapping him. He stirred at the contact, groggily looked me in the eyes, and let out a heavy groan.

It looked highly likely that he was just going to pass out again, so I grabbed both his solid forearms and hoisted him up. He was a big, well-built guy, so I couldn't exactly carry him, just forcefully guide him.

Somehow, I managed to get him on his feet and steered his heavy frame toward the wooden staircase. We negotiated the steps quite easily without any major accidents, save for a brief moment when his large hand accidentally grazed the curve of my ass while blindly blindly grasping for the banister to steady himself.

We finally reached the master bedroom door, and he mumbled a low, incoherent string of words that sounded vaguely like a 'thank you'. I left him there, tiptoed back downstairs to retrieve my laptop, and retreated to my own guest room. The soft bed was already perfectly made, so I simply collapsed onto the mattress without even bothering to strip off my day clothes, instantly passing out from sheer exhaustion.

It felt as though I had slept away half the day, but when I groggily checked the glowing screen of my phone, it was only a few minutes past 6 AM. My mouth felt like cotton; my throat was burning from intense dehydration. I slowly dragged myself out of the tangled bedsheets and padded quietly toward the kitchen downstairs.

Barely two minutes later, I was chugging my second bottle of chilled Frooti. The sweet, icy taste was purely divine. I carried the half-empty bottle with me as I trudged back upstairs, my body still feeling incredibly heavy and lethargic from the severely interrupted sleep.

And that was precisely when I heard the unmistakable sound. I was standing perfectly still at the very top of the stairs, and the noise was filtering clearly from the adjacent room—Divya and Karthik's bedroom. Incurably nosy as always, I silently crept closer and pressed my ear flat against the cool wood of the door.

Initially, the muffled noises sounded like a heated argument, followed by a soft, desperate pleading, which struck me as odd because my sister and her husband almost never fought. So, I held my breath and listened closer. It took a few extra seconds, but my brain finally recognized the rhythmic, wet sounds for exactly what they were.

They were having sex. And judging by the frantic pacing and breathy moans, it was hard, rough morning sex.

A heavy, pooling warmth instantly rushed between my thighs. I had never actually seen or heard them being intimate before, even though I obviously knew they fucked while I was staying over. I had a brief, fleeting internal debate regarding the moral merits of giving them their marital privacy versus satisfying my burning, dirty curiosity. My intense curiosity easily won the battle.

I scanned the edges of the door frame for any gap, but finding none, I realized I was going to have to do this old-school—just like back in college when we shared a hostel room and she would sneak guys in to hook up.

I quietly squatted down on the cool marble floor and pressed my eye to the metallic keyhole of the doorknob, praying silently that the key hadn't been left in the lock on the inside. It hadn't.

Their large king-sized bed was positioned directly across the spacious room, granting me an unobstructed, voyeuristic view. Karthik was laying flat on his back, naked and sweating, and my sister was straddling him fiercely, riding his thick cock like a wild animal in heat. His large hands were aggressively gripping her heavy breasts, slowly and rhythmically squeezing the soft flesh. Divya suddenly leaned all the way forward, hovering over his face so he could greedily suck her hardened nipples into his mouth, all while she maintained her relentless, bouncing pace on his dick.

I abruptly stood up, backing away from the door. Unconsciously, my own hands had flown up to cup my breasts; my nipples were agonizingly hard against my bra. I squeezed my own flesh, and the sharp, echoing sensation nearly tore a loud moan from my throat. I always had extremely sensitive breasts. Faint, rhythmic squeaking noises from the bed frame leaked from the room, and my filthy mind immediately began visualizing what explicit position they might shift into next.

I could literally feel my slick pussy juices trickling down my inner thighs as I quickly practically sprinted back to my own room. I dragged my heavy suitcase onto the bed and began frantically tearing through my clothes in search of my vibrating dildo.

It was an older, very reliable silicone piece, one I had practically worn out from continuous, desperate use. I frantically stripped off my clothes, throwing them onto the floor, and immediately shoved the toy deep inside my soaking wet cunt. I was entirely too riled up for any sort of slow foreplay.

As I aggressively fucked myself, thrusting my hips up to meet the silicone shaft, my free hand constantly alternated between rapidly rubbing my swollen clit and viciously pinching my sensitive nipples. The very first orgasm hit me like a freight train, shaking my entire body and curling my toes violently into the bedsheets, but I completely refused to stop pushing the toy in and out. Another intense climax followed mere moments later, and a loud, desperate whimper finally escaped my trembling lips. My fingers were completely slick with my own dripping juices, and still, I aggressively rode my hand.

The third orgasm was devastatingly slow and incredibly thorough, finally draining away the intense, frantic sexual energy that voyeuristically watching my own sister get fucked had sparked inside me.

I lay perfectly still on the damp sheets, totally unable to move a muscle, entirely unsure if I even wanted to, and just focused on breathing deeply to slow my racing heart.

Dawn fully broke about an hour later. I forced myself up, took a long, cold shower, and tidied up my messy room.

They were both downstairs in the kitchen when I finally descended. I heard their soft, happy voices echoing and walked casually in.

Karthik was standing closely behind Divya at the stove, suggestively rocking his waist against her firm ass while gently biting down on the sensitive skin of her neck. She was blushing furiously, softly elbowing his ribs to make him stop, though clearly without any real conviction. They heard my footsteps and instantly sprang apart, pretending to adjust their clothes.

"Morning, Archu," Divya chimed, overly cheerful. "How did you sleep?"

"Like a log," Karthik interjected with a teasing grin.

"It was fine. Good morning to you both." I yanked open the fridge for the second time that morning and grabbed a chilled bottle of water, trying not to stare at the noticeable bulge still lingering in Karthik's track pants.

Divya finished frying a massive batch of eggs, and we all sat down for breakfast. Karthik and I devoured toast and spicy masala omelets, while Divya strictly stuck to her healthy oats. She never really liked eggs.

"So, when is this big presentation of yours?" Karthik asked once we were all done eating, his wife casually lounging sideways across his lap as they watched the morning news on TV.

"Day after tomorrow," I replied smoothly, glancing at him briefly before returning my attention to the television screen.

"Wait, I thought you usually worked on Saturdays?" I asked him, remembering his typical IT schedule.

"He's officially on leave," Divya answered for him. As if anticipating my confusion, she quickly added, "They had an emergency yesterday, so he had to log in and go to the office."

"Massive server failure," Karthik groaned, rubbing his temples.

Just like me, he was deeply entrenched in the toxic, high-stress tech world. Perhaps that shared misery was why we always got along so effortlessly. Honestly, there were very few men I could converse with as naturally and unguardedly as I did with Karthik—especially men I hadn't already slept with, or wasn't actively plotting to sleep with.

"So, how is Varun doing?" he suddenly asked, catching me totally off guard.

"Who?" I blinked, confused.

"The tech lead guy you told us you were dating last time we spoke?" Karthik clarified, shifting Divya's weight slightly on his lap.

That made me lock eyes with him again. "Oh... right. I guess I didn't update you guys. We broke up. Completely ended things about three months ago."

"Oh, really? Why?"

Before I could answer, Divya suddenly slapped Karthik's knee. "Babe, shut up and look! Vijay is in this movie scene!"

I offered Karthik a small, mysterious smile and quietly promised, "We'll talk about it later." Nobody ever wanted to see Divya get annoyed over someone interrupting her favorite actor's screen time.

We lounged around watching Tamil movies for a bit longer until my work phone violently buzzed. I excused myself, heading straight back to my room to join a lengthy Skype sprint planning meeting with my development team, followed by hours of intense coding to patch a few bugs in the software we were prepping to launch.

It was already late afternoon when I finally stretched and headed back downstairs. The entire living room was dead silent, devoid of any human presence, and the kitchen was spotless and empty. I frowned, jogged back upstairs, and walked over to their master bedroom. I rapped my knuckles smartly against the wood, and Divya immediately pulled the door open. She had swapped her usual home attire for a pair of denim cut-off shorts and one of Karthik's oversized white t-shirts; entirely gone was the sheer, flimsy nightie she had been wearing just hours prior.

I walked in, and we immediately started tossing folded clothes into a large duffel bag resting on the bed.

I carefully sat on the edge of the mattress, fighting off vivid, filthy mental flashes of what explicit acts had been performed on these exact sheets less than eight hours ago. "So, where exactly are you running off to?"

"Mrs. Menon called. There's a crisis. I need to be in Coimbatore by tomorrow morning."

Mrs. Menon was the formidable founder of the Aashray Foundation, the aggressive NGO that passionately advocated for single mothers and rescued trafficked women. I glanced around the messy room, actively searching for Karthik. This NGO work was literally the only subject I had ever witnessed cause a serious rift between them. She had been forced to travel out of Chennai to remote towns twice since joining them, and both times, Karthik had vehemently protested. The fieldwork wasn't without its genuine risks, a danger my brave sister didn't seem to care about at all, but one that drove her protective husband absolutely insane with worry.

I deeply understood her motivations, at least in part. Our own mother had managed to raise the two of us almost entirely because a similar women's charity had financially and emotionally supported her. Divya felt a fierce need to pay that karma forward.

Just then, Karthik stomped out of the attached bathroom looking incredibly pissed off, his jaw tight. I wisely decided to make myself scarce and left them alone to hash out their argument behind closed doors.

Night fell surprisingly fast, and, exhausted from coding, I soon fell into a dreamless sleep.

I was jolted awake by my alarm at 5:00 AM the next morning to see my sister off. She and Karthik had clearly reached some sort of strained compromise. He definitely didn't like the trip, but he had reluctantly agreed to let her go. By 6:00 AM sharp, Divya was out the door with her husband driving her to the train station, and I happily crawled right back under my warm duvet.

I didn't emerge from my room again until roughly 6:00 PM. Karthik had obviously returned from the station hours ago. He was sitting heavily on the plush living room couch, rapidly typing away on his laptop, although the massive TV was blaring some random sports channel in the background.

"Hey. I thought you were still sleeping up there?" he asked, glancing up as I padded barefoot into the room.

"Nah, I was working," I responded casually, strolling over to drop down onto the couch right beside him. Almost immediately, I realized this might have been a highly dangerous idea.

He had changed into a pair of thin, grey cotton boxer shorts and a very loose-fitting v-neck t-shirt. It was actually the exact same shirt Divya had borrowed yesterday. My eyes instinctively dipped straight to his crotch and simply stayed locked there. It was an awful, dirty little pastime of mine; something I compulsively did whenever I was around attractive men—shamelessly sizing up the visible outline of their dick. Even soft, his package looked like it might be quite hefty, though from vast personal experience, I knew perfectly well how impressively a dick could expand when fully rigid.

He sighed, snapped his laptop shut, set it on the glass table, and grabbed the remote. We began watching a newly released thriller on Netflix. I crossed my arms tightly, hugging them securely beneath my breasts. The AC in the living room had been cranked up, making the air suddenly quite chilly, and I intentionally wasn't wearing a single thing underneath my thin cotton top. Absolutely no bra.

"Are you feeling cold?" Karthik asked, noticing my posture. "I can turn down the AC if it's freezing you out."

"No, no, it's totally fine. I just... didn't put on many layers," I replied softly, my voice dripping with subtle suggestion.

His dark eyes instinctively dropped straight to my torso and shamelessly lingered right on my breasts, where my sensitive nipples were completely, noticeably pebbled, blatantly poking hard against the thin, light-colored fabric of my shirt.

"Here, let me just..." I whispered boldly, physically lifting his heavy, muscular arm and deliberately tucking my own body right into his side, pressing against his warmth. "Much better."

I could literally feel his intense, burning gaze staring down at my body from above. I felt the raw, radiating heat from his chest as my soft breasts and hardened nipples repeatedly, intentionally grazed against his ribcage with every breath I took, in a way that made me desperately want to throw my head back and moan out loud.

This was a massive, dangerous leap, no doubt about it. Yes, we had always hugged, playfully pecked each other's cheeks, and casually talked about sex in all its versatile forms—but this was entirely different. There was something undeniably, electrically intimate about silently watching a movie in a dark room with a married man's arm wrapped protectively around your shoulders. If he found my sudden, clingy behavior strange or inappropriate, he absolutely didn't let it show. We watched the film in relative, heavy silence, save for the deliberate moments I aggressively burrowed even deeper into his side, or when I casually let my hand fall onto his thick thigh, absentmindedly stroking the warm skin.

When the movie credits finally rolled, I leaned forward slowly to grab the remote from the coffee table, intentionally sticking my ass—clearly and perfectly shaped out in my tight, tiny denim bum-shorts—directly into his line of sight.

I switched the TV off and stood up slowly. His dark, hungry eyes were shamelessly fixed on my lower body, while my own gaze darted straight down to his crotch, which was now sporting a highly visible, unmistakable hard-on tenting his grey boxers.

A wicked idea sparked in my mind. "Wait here. There's something I really want you to see," I purred, the deep huskiness in my voice not at all intentional this time.

I sashayed up the stairs to my room and quickly changed into one of the clothing options I had meticulously laid out for the crucial board meeting tomorrow, draping the alternative outfit carefully across my forearm.

I came back downstairs wearing a sleek, black corporate blouse paired with a high-waisted, tight grey pencil skirt that perfectly hugged every single curve of my hips and completely accentuated my round ass.

I stood confidently directly in front of him and asked, "So? What do you think?"

Before he could even form a response, I executed a painfully slow, deliberate twirl, ensuring he got a full, comprehensive view of all sides, taking agonizingly long, seductive pauses right when my ass was presented fully to his face. His eyes were blown wide open when I finally faced him again, the bulge in his shorts straining the fabric to its absolute limits, so I shamelessly spun around once more.

"It... it looks really nice, Archana," he managed to choke out, his voice rough.

"Do you honestly think I should wear high heels with this, or stick to flats? I really don't want to come off looking too aggressively formal for the client," I asked innocently.

"Heels. Definitely. Or flats. I mean, either would work perfectly on you," he stammered, completely flustered, and I offered him a wicked, knowing smile.

"Okay, now for option two..." I boldly stepped right behind the high back of the couch. Maintaining intense eye contact, I reached back, unzipped the tight skirt, and let it pool at my ankles. Then I slowly unbuttoned the black blouse, shrugging it off my shoulders until I was standing right there in his living room in absolutely nothing but my lacy black bra and matching, tiny panties. I was dripping wet. The sheer, forbidden thrill of standing half-naked directly in front of my sister's husband was fueling my sex drive into absolute overdrive, unlike anything I had felt in months.

I gracefully stepped into a stunning, form-fitting navy blue dress, pulling it up over my thighs. Then, I walked out from behind the couch and stepped right into his personal space, standing so incredibly close that our bare legs were practically touching.

"Could you be a dear and help me with this zipper? I just can't seem to reach it," I murmured, turning my back to him and lifting my heavy hair off my neck.

For an agonizing five seconds, there was absolutely zero reaction from him, and panic briefly spiked in my chest, fearing I had pushed this dirty game way too far. My entire upper back was completely exposed to the cool air, with just the very top curve of my ass crack barely visible. The only piece of actual clothing I still had on beneath the unzipped silk was my black bra.

Eventually, I felt his large, calloused hands gently settle on my bare skin. They were incredibly soft, yet radiating intense heat. If he harbored any moral misgivings about the highly inappropriate position we were currently in, his steady hands didn't betray a single doubt. They were firm, confident, and gripped the fabric of my dress like he intimately owned it—like he owned *me*.

I felt a fresh, hot wave of slick liquid trickle down my inner thigh, forcing me to subtly squeeze my legs tight together to control the blinding jolt of pure lust that shot directly to my clit.

He seemed to be having genuine difficulty reaching the very top of the dress's zipper while seated, mostly because I was now standing in my three-inch heels. So, without a word, he placed his warm hands firmly on my waist and pushed himself up to a standing position.

Sensing his movement, I deliberately edged backward a fraction of an inch as he rose, leaving absolutely zero room for him to stand straight up without having my ass press firmly, inescapably against his rock-hard erection.

And I was absolutely right about my earlier visual assessment. He was completely rock hard, incredibly thick, and rigidly pulsing against the thin fabric of his boxers right against my cleft. Every instinct in my body screamed at me to just reach back and grab his heavy cock right then and there.

His warm hands slowly traveled up my spine, pulling the delicate zipper along, but he frustratingly stopped right below my shoulder blades.

"Is it stuck on the fabric?" I whispered breathlessly.

He just let out a low, rough sound, and then he did something that absolutely completely shattered my remaining restraint. He aggressively grabbed both of my upper arms and forcefully yanked my back flush against his broad chest. The sudden, rough movement forced my breasts to thrust sharply forward, my back arching violently as our bodies slammed together. I couldn't hold it in; a loud, desperate moan ripped through my throat.

The zipper glided smoothly all the way up this time, but I deliberately lingered, grinding my ass softly into his throbbing erection for three heavy heartbeats before finally stepping away. The navy silk clung to my curves like a second skin, the tight bodice pushing my breasts up into a spectacular, heaving display.

"This one," his voice was a deep, gravelly growl. "This one is much better. And definitely wear it with the high heels."

I flashed him a dangerously sweet, innocent smile. "Thank you, Karthik."

I hastily grabbed the discarded grey skirt and blouse from the couch and practically sprinted up the wooden stairs, incredibly eager to reach the safety of my bedroom and tear all my clothes off. I was absolutely drenched between my legs.

I violently threw my trolley bag open, desperately rummaging through my packed clothes in frantic search of my thickest black dildo, but I couldn't find it. Extremely frustrated, I was forced to settle for a much smaller, slender pink vibe—one that severely lacked in girth but made up for that distinct disadvantage by having a powerful motor.

I threw myself onto the bed, spread my legs wide, and shoved the buzzing silicone deep inside my dripping cunt, not wasting a single second on teasing or foreplay. I would have vastly preferred taking a brutal, sweaty pounding from something much larger and alive—like the massive cock currently throbbing downstairs—but this plastic toy was all I had. The vibrator wasn't incredibly fulfilling, but I was so blindingly turned on by our illicit encounter that it didn't take long for me to completely shatter. I came violently once... twice... a third time, until my brain totally lost count of the orgasms ripping through my spasming body.

I slumped back heavily onto the damp, ruined sheets, completely drained of all energy. I was acutely aware that I desperately needed a shower to wash away the sweat and slick juices, but I simply couldn't dredge up the physical strength to even stand up.

Right at that moment, the bedroom door clicked and swung open. Karthik stuck his head into the room... and immediately froze, his eyes widening in pure shock. The entire enclosed space reeked heavily of raw sex and highly concentrated pussy juice—my own musk was so incredibly thick and pungent in the air that I knew for a fact he couldn't possibly miss it. Thankfully, I was fully buried under the thick duvet, so he couldn't immediately tell that I was completely naked and spread-eagle beneath it.

"Uh... I'm just heading out to meet some college friends at a restobar in T Nagar. Might be pretty late. You can go ahead and sleep if you want, I have my spare key," he stammered out rapidly, his gaze actively avoiding looking at the bed.

I simply replied with a exhausted, jerky nod, physically incapable of doing much else. He hastily shut the door.

Sleep claimed me suddenly and swiftly, dragging my exhausted mind under and tossing me through a chaotic series of highly explicit, forbidden dreams involving me, Karthik, and entirely too much sweat, until the annoying shrill of my alarm clock finally woke me.

It was exactly 5:12 AM.

I dragged myself into the bathroom, took a scalding hot shower, and meticulously dressed in the sleek navy blue dress and heels. Karthik was already downstairs, brewing coffee, still looking a bit groggy from his late night out but fully dressed.

He kindly drove me to the main gates of the Anna Nagar estate, where my junior colleagues were already waiting in a parked cab. He offered me a warm smile, wished me the best of luck, and we sped off toward the tech park.

Roughly seventeen minutes before 7 PM that evening, I practically barged through the front door of the house, completely drunk with adrenaline and pure excitement. The massive software project had been unanimously approved by the client board; we were officially green-lit to start full implementation by next week.

Karthik was lounging in the living room and immediately saw the manic happiness plastered across my face. Without thinking, I threw my bag down, sprinted toward him, and literally jumped into his waiting arms. My legs instinctively locked tightly around his waist, and his large hands instantly grabbed two fistfuls of my firm ass to support my weight as he spun me around, laughing and hugging me tightly. I had passionately discussed every single painful detail of this project with him since its inception three months ago, so he knew exactly what a monumental victory it was for my team to secure approval on the very first pitch.

"We are definitely going out to celebrate tonight!" I practically screamed, grinning down at him. "I desperately need to change out of these stuffy work clothes. Just wait right here for me!"

I half-walked, half-sprinted up the stairs, hastily stripped off the restrictive navy corporate dress, and took a frantic, two-minute speed shower. I didn't even bother digging through my drawer for panties or a bra before I aggressively wiggled my naked, damp body into a clinging, brightly colored lemon-yellow jumpsuit that left absolutely nothing to the imagination.

Karthik was fully ready and waiting by the door when I finally bounced back downstairs. He had changed into a pair of dark, fitted grey jeans and a tight, dark blue V-neck t-shirt that perfectly showcased his broad chest and muscular arms. I shamelessly looked him up and down, openly complimented his rugged look, and we headed out into the warm Chennai night.

I tossed out a few eager suggestions regarding the exact vibe I was aiming for, and he flawlessly navigated his car through the chaotic traffic to a highly-rated, upscale restobar tucked away in the trendy heart of Nungambakkam. It was chic, boasted incredibly moody, dim lighting, featured beautiful modern decor, and thankfully wasn't overly crowded for a weeknight.

We snagged two high stools right by the glowing neon bar and kicked off the celebratory night by downing strong, icy cocktails and ordering plates of fiery, pepper-fried prawns. A DJ was spinning upbeat tracks, and there was a designated open floor for dancing, completely illuminated by a wildly sweeping kaleidoscope of vibrant disco lights.

I aggressively coaxed and pleaded with Karthik into braving the pulsating dance floor with me. He was an absolutely horrendous dancer, which just made me laugh hysterically. After a few embarrassing songs, I mercifully allowed him to retreat back to his bar stool, while I confidently stayed on the floor, dancing seductively entirely on my own. He steadily drank his whiskey and just intensely watched my body move under the strobe lights. And honestly, bathed in his heated gaze, I felt like the sexiest woman alive.

He finally joined me back on the floor after a while, and we drank even more. He was definitely getting drunk, playfully blaming me for being a bad influence, and then boldly ordering another round of shots. Staring up at his flushed, handsome face, I finally truly understood exactly what my sister found so utterly captivating about him. He was a genuinely good man, effortlessly easy to talk to, ruggedly handsome, and always seemed to have a witty, sharp comeback ready for all my sarcastic statements.

I dragged him forcefully by his strong hand right into the very center of the dense crowd. I guess heavy alcohol truly does grant people liquid courage.

He boldly spun me around, pulling my back flush against his broad chest. I leaned fully into his heat and began slowly, deliberately rocking my hips against him, my bare ass grinding relentlessly and aggressively into his hardened groin to the heavy bass of the music.

In that exact, sweaty, music-filled moment, a profound and dangerous revelation finally slammed into me with the force of a physical blow: I was wildly, completely, incurably attracted to my own sister's husband. And I desperately, violently wanted to fuck his brains out tonight.

To hell with the moral consequences.

We danced closely, grinding and sweating on each other for what felt like hours, and finally bought an expensive bottle of imported wine to take back with us as we stumbled out of the club. I fiercely snatched his car keys right out of his hand when he drunkenly started spewing absolute nonsense about being perfectly fine to drive us back to Anna Nagar. Like hell I wanted to end up wrapped around a streetlamp tonight.

He sat silently in the passenger seat, his dark, lust-filled eyes unapologetically staring at my profile the entire dizzying drive home. I honestly, genuinely considered just slamming the brakes, parking the car right there on the dark roadside, straddling him, and aggressively kissing the living daylights out of him. Just to forcefully see exactly what would happen next.

We finally reached the quiet house, and I walked shoulder-to-shoulder with him inside. He stumbled slightly in the dark hallway, and his large hand immediately shot out, firmly grabbing a massive handful of my ass to steady himself. This time, I knew with absolute certainty that it wasn't a drunken accident. It was entirely deliberate.

I had been shamelessly teasing him all night long, throwing out massive, glaring signs regarding exactly what I wanted from him. We moved silently deeper into the house, and without a single word of discussion, I aggressively grabbed his shirt and led him straight upstairs, pushing open the door to his and Divya's master bedroom.

"I really need a hot shower," he slurred softly, heavily sinking down onto the edge of the large mattress, burying his face in his large hands.

I totally agreed. "Oh yes. Yes, you definitely do. Come here, let's get these sweaty clothes off you."

I forcefully yanked on his wrists, demanding he stand up, and he obediently rose to tower directly in front of me. I eagerly latched my fingers tightly onto the hem of his dark t-shirt and smoothly pulled it up and over his head, finally fully exposing his naked, smooth brown skin to the dim bedroom light. He was in incredible shape, his torso lean and hard, though not overly, artificially muscular.

"And these..." I purred, boldly placing my hands directly onto the waistband of his dark jeans and aggressively shoving them downward. He drunkenly helped me kick them away, until he was left standing tall and completely exposed before me, wearing nothing but his tight black briefs.

I slowly sank down onto my knees right on the floor and firmly drew his strong legs apart, positioning myself directly between his thick thighs.

The moment I placed my trembling hands directly on the elastic band of his tight boxers, he suddenly grabbed my wrists, holding my hands firmly in place. "Archana? We... we really shouldn't do this."

I looked up through my lashes, slowly brought my face forward, and tenderly kissed his knuckles. I deliberately sucked each of his thick fingers deep into my wet mouth, swirling my tongue around them until his hesitant grip finally, inevitably loosened. I forcefully dragged the cotton fabric all the way down, proudly exposing his massive, heavily engorged dick, which sprang out, angrily pulsing right at eye level with my face.

I leaned in slowly, deliberately dragging my tongue up the very beginning of his firm left thigh, and then meticulously licking the right one, inhaling deeply to take in the incredibly heavy, musky, masculine scent of his hardened manhood. I was absolutely going to suck his soul out, and I wanted him to know it, to agonizingly anticipate the wet contact before I even touched him.

I shamelessly rubbed my soft cheek against the hot, rigid length of his throbbing cock, playfully using the tip of my nose to flick the heavy head side to side. He desperately hissed my name into the quiet room as I finally opened my jaw wide and took him fully into my hot mouth. I maintained intense eye contact, staring right up at him so he could physically watch his massive girth stretch my painted lips apart.

I placed one hand firmly beneath him, gently cupping his heavy, tight balls, and forcefully sucked him incredibly deep into my throat until my soft lips forcefully hit his coarse pubic hair and the thick head of his dick was securely lodged in my windpipe.

His large hands instantly shot out, violently fisting in my loose hair. He wasn't hurting me; he was just desperately seeking an anchor, groaning loudly. I slowly pulled my head back, drawing my lips up the slick shaft until only the pink, wet head of his dick remained trapped between my lips, before aggressively swallowing his entire length right back down. I violently repeated the sloppy action several times, my pace rapidly picking up speed. He was practically roaring as he stared down at me, and I fiercely stared right back, absolutely refusing to break the heated eye contact for a single second.

He suddenly began thrusting his hips forcefully, violently pushing his heavy cock hard against the back of my throat, and I completely surrendered my body, eagerly giving myself up for him to ruthlessly use.

He roughly pulled me completely off his soaked dick—thick, stringy strands of glistening saliva literally bridging the gap between my wet lips and his shiny cock—and forcefully pushed my head lower, down to his heavy balls. I happily sucked each one into my mouth, using my free hand to push his rigid dick upward so it lay flat against his taut abdomen.

I aggressively sucked, licked, and flicked my tongue over his sensitive sack, humming loudly with his flesh buried deep in my mouth just so he could physically feel the intense, vibrating pleasure.

He violently grabbed a fistful of my hair again, much rougher this time, and practically slammed my face back onto his rigid dick. I eagerly sucked him deep whenever his strong hands firmly guided my head down, but otherwise remained perfectly still when he clearly wanted to ruthlessly fuck my mouth himself. His jerky movements were becoming totally frantic as he aggressively pistoned my head up and down his slick shaft. He would roughly twist my face to the side just so he could violently fuck the soft inside of my cheek, and repeatedly slap his heavy, wet dick all over my swollen lips.

With my eager hands back on his heavy balls, vigorously stroking them, I sucked his entire length in incredibly deep and looked up into his wild eyes. He forcefully held my head rigidly in place by my hair, made three rapid, brutal thrusts with his hips, and violently started coming down my throat.

I desperately wanted to taste his seed, so I didn't utter a single protest. Thick, hot ropes of salty cum rapidly shot directly down my throat in incredibly quick, successive bursts until his heavy cock was completely drained. It certainly wasn't a delicate taste, but I definitely hadn't expected it to be as I greedily swallowed every single drop.

I gently pushed his hips back, broke the intense connection, and eagerly stood up to violently rip the bright yellow jumpsuit entirely off my sweaty body. When he saw with his own eyes that I was completely, gloriously naked underneath—no bra, no panties—something raw and primal inside him just totally snapped. He violently dropped to his knees right there on the floor and aggressively attacked my soaking wet pussy with an absolute vengeance. His tongue was hard, fast, and incredibly wicked as he greedily lapped up my thick, flowing juices, which were now practically gushing down my thighs.

I forcefully grabbed the back of his head, crushing his face right into my soaking crotch, and aggressively ground my hips against his mouth. My entire lower body violently jerked upwards whenever he expertly flicked his rough tongue rapidly across my swollen clit or gently nibbled the sensitive nub with his teeth.

I was so incredibly high on the illicit thrill, so blindingly hot from the forbidden act, that I barely even noticed he had firmly placed his massive hands tightly under my bare thighs and was physically lifting me entirely off the ground. That was a feat that wasn't very easy to do, considering my thick lower half was incredibly heavy. He powerfully carried my thrashing body right out of the bedroom and into the attached bathroom, forcefully pinning my bare back flat against the cold wooden door while he continued to ruthlessly eat me out.

I was literally screaming, violently thrashing my legs, and moaning at the top of my lungs, and he seemed absolutely intent on murdering me with pleasure. With a deliberate, powerful flexing of his biceps, he began slowly sliding my body down the smooth wood, only to firmly settle my dripping, wide-open pussy directly onto the head of his massive dick, which had somehow miraculously become rock hard all over again.

Slowly, agonizingly, he sank my weight down entirely onto his thick shaft until only a tiny fraction of him remained visible outside my body, and then he brutally, violently slammed his hips upward, sinking himself to the hilt. "Ahhhh! Fuck!" I screamed as I violently came, my entire body rigidly locking up. My arms were desperately wrapped around his thick neck, holding on for dear life with all my fading might as he aggressively, relentlessly fucked the absolute life out of me.

My bare legs dangled uselessly off the floor as he kept violently thrusting his heavy hips into me, rapidly setting the perfect, chaotic stage for a second explosive orgasm. I moaned incredibly loud as I threw my head back against the door, burying my nose into the sweaty crook of his muscular shoulder, desperately urging him with filthy, slurred words to just completely destroy me. "Oh yes... fuck, yes! Harder Karthik, break me!"

And he absolutely did.

My soaked pussy felt like it was literally on fire, and I violently came a second time. And still, he just relentlessly kept fucking me deeper.

The bathroom door suddenly popped open under the immense pressure of our continuous, violent banging, and we both literally stumbled backward into the tiled space. We forcefully backed into the opposite wall, the shockingly cold shower tiles suddenly kissing my burning skin.

I immediately wrapped my shaking legs even tighter around his sweaty waist, violently pushing his thick cock even deeper inside my slick body. He aggressively grabbed both of my wrists and forcefully slammed my hands flat against the wet tiles high above my head, pinning them there securely with just one massive fist while his mouth violently descended to feast on my heavy, bouncing breasts. He ruthlessly bit and sucked on my swollen nipples, and I exploded into a third, blinding orgasm right as he finally released my legs, letting me drop heavily onto my own two feet.

My legs instantly felt like absolute jelly, totally unable to support even a fraction of my own weight, and he practically had to catch me, gently helping me step right into the massive, dry bathtub.

I instantly turned around, grabbed the porcelain edge, and shamelessly presented my thick, wide-open ass directly to him, my sweaty body forcefully nudged deep into the corner of the tub to gain some desperate traction for when he inevitably violently entered me from behind.

He agonizingly ran the thick, wet head of his heavy dick slowly up and down the slick, swollen folds of my soaking pussy, teasing me relentlessly before violently pushing himself all the way in with one brutal shove. I let out a pathetic, high-pitched whimper as he slammed deeply into my core, totally unable to formulate words or do anything else other than just stand there and take the brutal pounding. I could easily tell he was rapidly nearing a massive climax. The violent motion of his hips became frantic and incredibly fast, his desperate thrusts growing shallower but impossibly harder.

Desperate for more of him, I reached back with both hands and forcefully grabbed my own ass cheeks, spreading myself as wide apart as physically possible just so his thick shaft could plunge even deeper into my guts. He aggressively reached around my waist and began rapidly flicking my swollen clit, totally pushing me over the edge. The violent, earth-shattering orgasm that ripped through my body was so sudden and completely unexpected that my vision literally went white. My entire frame went rigidly stiff, and I aggressively clamped down on his thick cock, violently milking it of absolutely everything inside.

He came with a loud roar right inside me, aggressively burying his entire heavy length so impossibly deep, it felt like he literally wanted to crawl inside my womb and stay there. Our loud, ragged breathing aggressively bounced off the bathroom tiles as we slowly, painfully came down from the blinding sexual high.

He finally pulled his slick, softening cock out of my dripping body after a long, heavy minute and just immediately collapsed onto the cold porcelain edge of the tub, resting his head in his hands, aggressively panting for air.

When my shaking legs could finally support me again, I turned on the showerhead, quickly cleaned myself up, and gently pulled his heavy frame in under the warm water so I could softly wash the sweat and cum off his body too. He looked completely lost, utterly drained, and visibly confused, and a tiny part of my soul felt a pang of deep sadness that he might have instantly regretted this incredible mistake.

The remaining days of my stay in Chennai flew by in an agonizing blur after that explosive night. Divya returned from Coimbatore exactly four days after we fucked like wild animals. Karthik and I never officially spoke of the incident again, and we deliberately, awkwardly avoided spending any significant time alone in the same room for the entire remainder of her busy trip.

I did feel a heavy, undeniable amount of guilt for forcing him to betray my sister like that, for turning him into a liar, because we both silently, absolutely understood that we could never, ever tell her. We both non-verbally agreed on that fact. And there were nights when the guilt physically hurt.

But honestly? There were far more frequent nights when I lay awake, soaking wet in her guest bed, desperately hoping he was lying beside his wife getting a rock-hard erection just thinking of me, and wildly craving for him to burst into my room and ruthlessly fuck me senseless from behind exactly like he did that night.
