[KURUBUSI-KAI (Dowarukofu)] Loli Bakunyuu no Imouto All Color [Full Color]

A buxom, petite stepsister with wide green eyes trembles as her brother's rough, dominating hands explore her massive, bouncing breasts, her voice pleading "stop already... I'm scared... onii-chan~" while her body betrays her arousal. She shifts between desperate resistance and helpless submission—crying "kyaa aaaaa" one moment and offering "I'll help you feel even better and better" the next—her tight body glistening with sweat under the full-color artwork. The forbidden tension between bloodline loyalty and raw desire builds until she breaks completely, riding him with trembling legs and parted lips, cum dripping down her thighs in the aftermath.
