Natsuko Kayama is a legend who has a top career in the AV industry, but is still evolving as a mature actress. In this film, she shows us "serious pleasure-crazy sex"! She sucks up her favorite big dick with a lewd face, squeezes it between her huge breasts, and pistons it ferociously in a big-ass cowgirl position! She goes crazy with oil, slutty sex that teases with dirty talk and vulgar poses, raw creampie sex that shakes her voluptuous body... it's a little different from what we've seen before, and it's almost beastly lewdness!
