In the fourth installment of the Iji Rental Prologue, our protagonist is tormented by his older sister, Yuu. She tantalizes him with her luscious curves and dominance, demanding a footjob. Her big, bare breasts heave as she controls his movements, guiding his eager mouth to her soles. The tension builds as she orders him to missionary, his throbbing cock ready to burst. Ignoring his pleas, she denies him release, leaving him aching for more.
