A beautiful girl, Mamiru... A middle-aged man with pent-up desires sneaks into her house, and her lustrous black hair... firm white skin... young yet voluptuous body... are transformed from innocent white to sinful jet black by unforgivable lust. Her crotch gets wet from the rough kisses and caresses, and her vagina is thrust hard into by his penis, and milky semen explodes on her pretty face. *This work is a re-edited version of "Kuchibiru" (product code: cwm00125).
