In this adult niece role-play, Haru has always been intensely curious about sex. Whenever she visits, she asks to play doctor, wants to bathe together, and shows open fascination with men's bodies and cocks, leaving the men of the household unsure how to handle her. When she returns after a long absence, she now has enormous J-cup breasts. Wearing no bra, she boldly presses her soft tits against them and tempts them into crossing the line.
