A younger sister comes to visit her older brother who lives alone. She can't help but stare at his growing breasts with an erotic gaze. The younger sister watches the adult videos her older brother had hidden and indulges in masturbation. She falls asleep. When her brother comes home, he plays with her tight thighs that are sticking out from under her skirt. "Big brother, stop..." He licks her pussy through her clothes and makes her put it in her reluctant little mouth.
