I agreed readily—"Beta hai meri, ghar aa jaye." But when Riya arrived that rainy July evening, suitcase in hand, she wasn't the awkward teen I'd last seen at family weddings. She was a full-grown woman: shoulder-length straight hair with trendy layers, innocent wide eyes that hid a spark of mischief, a bright smile with dimples, soft fair skin, and a body that caught me off guard—perky 34D breasts pushing against her college t-shirt, a slim waist from her swimming hobby back home, flaring hips, and a thick bubble ass that filled her leggings perfectly, jiggling subtly as she climbed the stairs. "Mama ji!" she hugged me tightly at the door, her young softness pressing into me, faint floral perfume mixing with rain. I felt an unwelcome twitch but dismissed it as uncle affection.
The flat had two rooms—mine and the guest one turned study. But with her late-night studying, we often shared the living room couch for "quick doubts." Coaching classes ran day-long; evenings she returned exhausted, I'd cook simple dal-chawal or order in. Nights were when closeness grew. Mumbai monsoons meant frequent power cuts—fans stopping, heat rising. We'd light candles or use phone torches, sitting on my bed (cooler room) to study or chat.
First weeks: innocent. She'd change into loose nighties or shorts and tank tops for comfort, no bra in the heat—nipples faintly visible when bending over books. "Mama ji, yeh physics samajh nahi aa raha," she'd say, scooting close on the bed, thigh touching mine, soft breast brushing my arm as she pointed to diagrams. I'd explain patiently, but my eyes drifted to her cleavage or the way her shorts rode up, showing smooth thighs.
Tension built slowly. One storm night, thunder crashing, power gone for hours—she got scared, "Mama ji, dar lag raha hai... saath baitho na." Cuddled under one blanket "for warmth," her head on my chest, leg draped over mine. Her young body heat seeped through thin fabric; I felt myself harden against her hip. She shifted but didn't move away—instead pressed closer, breathing quickening.
Talks turned personal—she confessed stress, no boyfriend ("Boys immature hain mama ji... aap jaise caring koi nahi"), missing home. I shared loneliness post-auntie's death. Tears came; I wiped them, stroking her hair. "Mama ji... aap mere hero ho." The cuddle intensified—her hand on my chest, mine on her back drifting lower to waist. Eyes met in candlelight; she leaned up, lips brushing mine softly. "Yeh galat hai Riya... main tera mama hoon." But she whispered, "Sirf ek baar... please mama ji."
The kiss deepened—tongues exploring forbidden sweetness. Hands roamed; I peeled her tank top, revealing perfect young tits—firm, bouncy, pink nipples erect. Cupped them gently, thumbs circling before sucking one greedily, tongue flicking as she arched. "Ahhh... mama ji... chooso zor se... bhanji ke boobs pi lo," she moaned softly, fingers in my hair, body writhing.
She reached into my lungi, wrapping soft hands around my thick 7.5-inch cock (widowhood had kept it hungry). "Mama ji ka lund... itna mota aur garam." Stroked shyly, then bent to lick the head, taking it in her warm mouth—eager but learning, bobbing deeper with guidance, saliva making it slick, gagging cutely but persistent.
I laid her back, removing shorts—panties soaked, shaved teen pussy pink and puffy. Rubbed her clit, fingers sliding into tight virgin-like heat (she'd fooled around but not fully). "Geeli ho gayi bhanji... mama ke liye?" Ate her hungrily—long licks, sucking clit, tongue deep until she came hard, thighs clamping, juices sweet on my tongue, muffled screams into pillow.
Positioned at entrance, rubbing cock along slit. "Dalun andar beta? Teri seal tod dun?" She begged, "Haan mama ji... apni bhanji ki virginity le lo... chod mujhe." Pushed slowly—impossible tightness gripping, pain turning pleasure as she urged deeper. Thrust building—tits bouncing, nails digging my back. "Zor se chod mama... haan aise phod do!"
Switched—cowgirl: she rode learning rhythm, ass slapping thighs; doggy: gripping bubble ass, spanking lightly as it jiggled; missionary: legs wrapped, deep intimate strokes whispering "I love you." Came multiple times, pussy milking. "Andar daal mama... creampie kar bhanji ke andar!" Flooded her young womb.
Nights became sacred. Power cuts: candlelit slow sex on floor. Study breaks: quick oral under desk. Balcony risks: monsoon rain masking moans as fucked against railing. Experiments—anal after lots of fingering and lube (she cried pleasure, addicted to fullness), light bondage with her scarf tying wrists, role-play as strict teacher-uncle punishing "naughty student."
Emotional bond—she felt safe exploring with trusted mama, stress melting in orgasms; I found purpose protecting yet claiming her youth. Coaching ended; she "extended" for "results wait." Flat our secret haven—Mumbai chaos outside, passion inside. Our forbidden nights eternal.
