Mizusawa Tsugumi is grabbed by her brother's thick, hard cock. Though her mind resists, she fears being hated by him and cannot help but offer her small body to his daily harassment. When ordered to pour her saliva into his mouth, she squirms her lips and obediently drips thick saliva, then takes his erect cock into her mouth, using her small lips to service him diligently, accepting his cum. At night, her father routinely defiles her mouth with deep throat, spreads her shaved pussy wide, and brings her to leak arousal through intense cunnilingus. When his huge cock thrusts deep into her tiny, tight folds with twisting motions, she ascends with an expression between pain and pleasure. Filled to the womb with her father's thick cum, she once again becomes the family's sex doll. And the next day, she will again be stained by the cum of both father and brother.
