XVSR-906 Secret Days of Sweet, Intimate Passion with My Glasses-Wearing Younger Stepsister, Kept Absolutely Hidden from Our Parents — Mikan Kosuzu

After his father remarried, he suddenly gained a stepsister: a busty but plain, quiet girl who wore glasses. He became fixated on her and, whenever he got the chance, secretly took her underwear and indulged in private fantasies while smelling it. Noticing her brother’s behavior, the sister began tempting him, and the two spent their days secretly enjoying a forbidden relationship without their parents finding out. The stepsister he had thought was plain turned out to be surprisingly bold and forward, and seeing her intensely passionate side left him so excited that he could not stop himself.
