The younger sister, a petite anime schoolgirl, is haunted by her lust for her older brother. She finds him studying, his back to her, and can't resist the urge to touch him. She presses her small, firm breasts against his back, her hands snaking around to stroke his chest. He stiffens, but she can feel his heartbeat quickening. She moves her hands lower, tracing the lines of his abs, her fingers brushing against his hardening cock. He turns to face her, his eyes dark with desire. She smiles, her tongue darting out to lick her lips, before dropping to her knees, eager to worship his throbbing cock with her mouth.
