Hi, my name is Siddharth Gupta, and this is the true story of the most taboo and unforgettable experience of my life when I was 25. It happened during the first brutal COVID lockdown in 2020, when the whole country shut down and everyone was confined indoors. Our family lived in a spacious 3BHK flat in a posh Delhi society—marble floors, big balconies, and AC in every room—but with parents stuck at relatives' place in another city due to sudden restrictions, it was just me and my younger sister, Priyanka, trapped together for weeks. Priyanka was 20 then, a second-year college student doing online classes, innocent and sheltered in our conservative middle-class family. She was a typical desi beauty—fair skin with a pinkish glow, long straight black hair that reached her waist, big doe-like eyes with natural kajal vibe, and a body that had blossomed beautifully: perky 34C breasts that jiggled slightly under her loose tops, a slim waist, and a round, firm ass that swayed when she walked around the flat in her shorts or leggings. As her elder brother, I'd always been protective, but being locked in together 24/7, with no outings, no friends, just endless boredom, something shifted inside me.
The lockdown days were monotonous—waking up late, online work for me (I was interning remotely), her classes on laptop, then binge-watching shows or playing board games. The flat felt smaller, hotter despite AC, the air thick with cabin fever. Priyanka wore comfortable home clothes: oversized t-shirts without bra sometimes (I noticed the faint nipple outlines), short shorts that hugged her thighs and ass, or tight leggings that outlined everything. At first, it was innocent sibling stuff—I'd tease her about her lazy ponytail or how she hogged the TV remote. "Didi nahi, tu meri chhoti behen hai, remote de," I'd joke, wrestling playfully for it. We'd end up tumbling on the sofa, bodies pressing accidentally—her soft breasts against my chest, her thigh over mine—and she'd giggle, blushing, pushing me away. "Bhaiya, mat karo na," she'd say breathlessly, but linger a second longer each time. Guilt hit me hard—she's my little sister, pure and virgin as far as I knew—but the taboo thrill made my cock twitch, imagining more.
Tension built slowly through small moments. Mornings, she'd make chai in the kitchen, bending to get milk from the lower fridge shelf, her shorts riding up to show the bottom curve of her ass cheeks, smooth and creamy. I'd stand behind, pretending to help, my crotch brushing her hip "accidentally." "Sorry, Pinky," I'd mutter, but feel the heat. She'd straighten up, face flushed, "Bhaiya, jagah kam hai na," but her eyes would dart down briefly, noticing the bulge. Afternoons, during power naps in the living room (AC in bedrooms conked out one week), we'd share the big sofa—her head on my lap, my hand resting on her waist. Her t-shirt would ride up, exposing her flat stomach and navel, and I'd trace circles absentmindedly, feeling her skin goosebump. "Bhaiya, gudgudee lagti hai," she'd whisper, but arch slightly, pressing into my touch. My mind raced with forbidden thoughts: What if I slide higher, cup those perky tits? No, Siddharth, she's your behen, blood sister—I'd scold myself, but jerk off later in the shower, picturing her innocent face moaning.
Evenings amplified the tease. We'd cook together—simple dal-chawal or maggi—standing close at the counter. She'd reach for spices above, her body brushing mine, breasts grazing my arm. "Bhaiya, yeh packet de na," she'd say, and I'd hand it, fingers lingering on hers. Once, while chopping onions, tears in her eyes, I wiped them gently, thumb on her cheek. "Ro mat, Pinky," I said softly, and she leaned into my hand, eyes closing. The air crackled—her scent of dove soap and faint feminine sweat intoxicating. Lockdown boredom led to truth-or-dare games late at night. Innocent at first: "Dare you to dance like Salman Khan." But dares escalated—she'd twerk playfully in her shorts, ass shaking teasingly, laughing as I stared open-mouthed. "Bhaiya, bandar jaise dekh rahe ho," she'd tease, but sit closer after, thigh pressed fully against mine. My dares: make her sit on my lap "like old times." She'd comply shyly, wiggling to get comfortable, feeling my hardness grow beneath her. "Bhaiya, kuch hard hai," she'd whisper innocently once, blushing crimson, but not moving away. Internal lust boiled: I wanted to grab that ass, kiss her full pink lips.
The buildup peaked with shared baths stories—no, we didn't bathe together, but laundry days she'd hand me her clothes, including lacy bras and panties, damp sometimes. "Bhaiya, dhona padega," she'd say embarrassed. I'd smell them secretly—her musky scent driving me wild. One rainy evening (Delhi monsoon even in lockdown), power cut, we lit candles and talked deep—about her crushes (none serious), my exes. "Bhaiya, kabhi kiss kiya?" she asked curiously. I nodded, and she probed more, eyes wide. "Dictate karo na, kaise hota hai." Playfully, I pecked her cheek—brotherly—but she turned, lips brushing mine accidentally. We froze, then laughed it off, but the spark ignited. That night, unable to sleep in the heat, she came to my room. "Bhaiya, dar lag raha hai andhere mein, saath soyun?" Innocent request like childhood, but now charged. She slipped under my sheet in her thin camisole and shorts, back to me. I spooned protectively, arm over her waist, hand inches from her breasts. Her ass pressed against my crotch, soft and warm. "Pinky, jagah adjust kar," I murmured, but ground subtly. She sighed, pushing back, and my cock hardened fully, nestling between her cheeks. Guilt warred, but lust won—we pretended sleep, breathing heavy.
The explosion happened a few nights later. Restless heat, both in AC-less room on my bed for "cooler fan." She wore just a loose tank top and panties—bra forgotten in humidity—nipples poking clearly. We talked whispered secrets, her hand on my chest "casually." "Bhaiya, lockdown mein bahut bore ho rahi hoon... kuch exciting chahiye," she confessed. I teased, tickling her sides—she squirmed, laughing, body writhing against mine. Play turned heated; she straddled me to pin my hands, breasts hanging in my face, tank strap slipping to reveal one pink nipple. "Pinky..." I groaned, staring. She blushed but didn't cover, grinding down instinctively on my hard cock. "Bhaiya, yeh kya hai itna hard?" she whispered, curiosity mixing with desire. Taboo shattered—I pulled her down, kissing deeply. She hesitated—"Bhaiya, yeh galat hai... hum siblings hain"—but responded hungrily, tongue shy at first, then eager. "Ahhh... kiss karo mujhe," she moaned, tasting of strawberry lip balm.
Hands explored—I slid under her tank, cupping her perky 34C breasts, soft and firm, pink nipples hard like pebbles. I pinched them gently, rolling between fingers as she gasped "Bhaiya... chhuo na... ahh." Top off slowly, revealing her naked torso—smooth, milky skin glowing in moonlight. I sucked one nipple greedily, tongue swirling the areola, tasting faint salt, biting lightly while kneading the other. "Chuso behen ke boobs... zor se bhaiya," she begged, cradling my head, body arching. Her moans—soft, desi "ahhh... ummm"—filled the room.
She tugged my t-shirt off, hands exploring my chest, then down to my shorts, freeing my throbbing 7-inch cock, thick and veiny, pre-cum oozing. "Bhaiya, kitna bada hai... pehli baar dekh rahi hoon," she whispered in awe, stroking tentatively, soft palm gliding slickly. I taught her— "Aise pakdo, upar neeche," groaning as she pumped faster.
I peeled her panties—her virgin pussy shaved lightly, pink lips glistening with wetness. Musky virgin scent hit me. I rubbed her clit gently, fingers tracing folds. "Geeli ho gayi meri chhoti behen," I teased, slipping one finger in—tight, hot. "Ahhh... bhaiya ungli daalo... dheere," she bucked, walls clenching. I finger-fucked slowly, adding second, curling to her spot till she came—body shaking, juices flooding, moaning "Aa raha hai... bhaiya!"
She wanted to taste—bent shyly, lips kissing the head, tongue licking pre-cum salty-sweet. "Muh mein le, Pinky," I guided, and she sucked eagerly, bobbing, saliva dripping, learning fast. Wet sounds erotic in quiet night.
I spread her legs, rubbing cock on her slit, teasing virgin entrance. "Daloge bhaiya? Dard hoga," she whimpered, but legs wrapped me. "Dheere se chodunga apni behen ko." Pushed in slowly—popping her cherry, tight resistance giving way to velvet heat. "Ahhh... phad diya bhaiya ne... pura andar," she cried tears of pain-pleasure. I waited, kissing her, then thrust gently, building rhythm. Her breasts bounced, sweat slicking us. "Chod mujhe bhaiya... zor se... haan aise," passion overtook innocence.
Missionary deep, her nails digging. She rode next—awkward at first, then grinding wildly, ass slapping, pussy clenching. "Behen upar baith ke bhaiya ka lund le rahi," she panted taboo. Doggy—her round ass high, me pounding, watching cheeks ripple, spanking lightly. "Thappad maro... pel behen ki chut." Multiple orgasms—she shuddered thrice, virgin body sensitive.
"Cum inside bhaiya... behen ke andar bhar do," she begged. I exploded—hot creampie filling her, milking every drop as she came again.
Rounds continued—69, her tasting our mix on me while I lapped her creamy pussy. Slow side fuck, whispering "Love you bhaiya... forever." Exhausted, entwined in forbidden afterglow.
Lockdown secrets bound us deeper, stolen moments in the flat, craving each other's touch always.
