Her cunt clenched around my fingers one final time, and then I felt it—the rush of wetness, the spasming of her walls, the way her whole body went rigid before shuddering against mine. She came silently, beautifully, her teeth sinking into my palm to muffle the scream I knew was tearing through her. Her thighs squeezed together, trapping my hand, and I felt every pulse of her orgasm against my fingers, hot and desperate.

I held her through it, my cock throbbing painfully against her ass, and when the tremors finally subsided, I pulled my fingers free. They were soaked—coated in her slick, shining arousal—and I brought them to my nose, inhaling deeply. She smelled like heaven. Like sin. Like everything I'd ever wanted and shouldn't have.

"Nicki," I breathed, and my free hand was already fumbling with my belt, my zipper. "I need—I need to be inside you. I can't—I can't wait anymore."

She turned her head, and those sexy eyes—darkened now, pupils blown wide with lust—met mine. Her lips were parted, swollen from biting them, and her chest was heaving, those perfect breasts straining against the tight t-shirt. She looked wrecked. Beautiful. Forbidden.

"Then don't wait," she whispered, and her voice was a command wrapped in velvet. "Do it, Uncle."

I freed my cock, and it sprang out, hard and aching, the tip slick with precum. I hiked her skirt up higher, exposing the smooth, milky white curves of her ass, and I groaned at the sight—her skin was flawless, glowing faintly in the dim light of the bus. I positioned myself, pressing the head of my cock against her wet entrance, feeling the heat radiating from her.

"Fuck, Nicki—you're so wet," I groaned, sliding the tip along her slit, coating myself in her arousal. "So fucking wet for me."

She whimpered and pushed back, and the head of my cock slipped between the swollen lips of her cunt, pressing against the tight, hot opening. I grabbed her hip with one hand, steadying myself, and then I pushed forward—slowly, inch by agonizing inch—into the tightest, hottest, most perfect heat I'd ever felt.

"Oh God—" I groaned, my head falling forward against her shoulder. "Oh fuck, Nicki—you're so tight. So fucking tight."

She gasped, her lips parting, and I felt her walls clench around me, gripping my cock like a fist. She was trembling—I could feel it in her thighs, her back, everywhere we touched. I bottomed out inside her, my hips pressed flush against her ass, and I held there, savoring the feeling of being buried inside my niece for the first time.

"Move," she breathed, and her voice cracked. "Please, Uncle—move."

I pulled back slowly, feeling every inch of her gripping me, and then thrust forward, hard. She gasped, her body jolting, and I set a rhythm—slow at first, deliberate, savoring every stroke. My hands roamed freely over her body, sliding up beneath her t-shirt to cup her bare breasts, pinching those pink nipples I'd dreamed about for so long.

"Harder," she commanded, and her voice was stronger now, more certain. "Fuck me harder, Uncle. I want to feel you."

I obeyed. I thrust deeper, harder, my hips slamming against her ass with each stroke. The sound of skin meeting skin was soft, muffled by the rumble of the bus, and I prayed no one could hear. My hands gripped her hips, fingers digging into the soft, smooth flesh, and I pounded into her, raw and desperate.

"Uncle—" she moaned, and the word sent a jolt of electricity through me. "Uncle, yes—like that—don't stop—"

"Say it again," I growled against her neck, my teeth grazing her skin. "Call me Uncle while I fuck you, Nicki. Say it."

"Uncle," she gasped, and her cunt clenched around me. "Uncle—fuck—your cock feels so good inside me—"

I lost all restraint. I fucked her harder, faster, my cock slamming into her wet cunt with each thrust, my hands gripping her breasts, her hips, her thighs—every inch of her I could reach. She was pushing back to meet me, her ass grinding against my hips, and the wet, obscene sounds of our fucking filled the small space around us.

"Tell me what you want," I panted, my forehead pressed against her shoulder. "Tell me, Nicki—anything—"

"Touch me," she demanded, grabbing my hand and shoving it between her legs, pressing my fingers against her clit. "Make me come again, Uncle—while you're inside me—"

I rubbed her clit in tight circles, my cock still pounding into her, and she shattered—her whole body convulsing, her cunt clenching so hard around me that I saw stars. I clamped my hand over her mouth again, swallowing her scream, and I followed her over the edge, burying myself deep inside her as I came, my cock pulsing, filling her with everything I had.

We stayed like that, trembling, breathing hard, my forehead resting against her shoulder, my cock still buried inside her. The bus rumbled on, and somewhere ahead, a passenger coughed.

Nicki turned her head, her lips brushing my ear.

"Again," she whispered. "I want you to do that again."
