Jun, who plays the niece, grew up under her uncle's loving care, innocent and utterly ignorant of matters between men and women. One day, her uncle, under the pretext of letting her try his new perfume, secretly slipped a sleeping potion onto a handkerchief and gently covered her mouth and nose. The girl quickly fell into a deep sleep, her delicate body limp on the bed. Her uncle, with trembling hands, unbuttoned her clothes, revealing her large, white breasts, the pink nipples trembling slightly in the air. He greedily took them into his mouth, sucking and licking, and the girl unconsciously moaned in her sleep. Her uncle pulled down her panties, his fingers probing her untouched vulva, feeling its tight warmth. He could no longer resist, pulling out his already erect penis and thrusting it forcefully into her. The girl frowned slightly, but the drug prevented her from waking. Her uncle began to thrust violently, each stroke reaching its deepest point, his penis moving in and out of the tight passage, drawing out glistening fluids. He changed positions, hoisting the girl's legs onto his shoulders, and thrust wildly hundreds of times before finally penetrating deeply, ejaculating thick semen that filled her womb. The girl's genitals were thoroughly penetrated, and even in her drowsy state, they instinctively contracted, as if welcoming this forbidden violation.
