Young and Japanese.
Ah, the wonderfully bizarre world of Japanese porn. It seems that, in this genre, even the videos purporting to consist merely of innocuous smut contain at least a few bits of somewhat unusual material.
Case in point is this tape's second scene. A very young, very cheery girl named Mika, dressed (somewhat) in a nurse's outfit, is standing in front of a bed. She pulls the covers back to find a man lying in it. His face is painted brown. Mika then happily jumps on top and fervently fellates him while he photographs her. This all transpires in front of a large, strange, almost surrealist-looking painting (think somewhere between Picasso and Dali).
In another scene, a half-asleep (or perhaps tipsy) Yukiko grimaces and sighs as a dildo is thrust in and out of her. She refuses to lick it after her climax.
Probably the best scene is the one with Keiko, who possesses an interesting physiognomy ¾ she just barely looks Asian. Wildly orgasmic, she takes five dildos in her pussy and one in her ass. This eventually leads to some inspired fucking on the floor.
Overall, the action here is a good deal more energetic than a lot of this genre's typical fare.
