Innocent flat-chested girl Tsumugi Muto makes her creampie debut! She has a baby face, immature A-cup breasts, modest areolas and inverted nipples. NON endlessly teaches the beautiful young girl Tsugumi the pleasures and sexual techniques of sex. Her overly sensitive small breasts and inverted nipples are thoroughly sexually developed, and she is given deep throating by a huge cock, and even has a creampie orgy. Her mind and body have been taught that "creampie is something to do and something to be done" and she is repeatedly thrusted hard by a big man's huge cock, her body trembling as she climaxes.
