Sakura, a glamorous dominatrix-teacher (she looks like a Manga drawing), goes around disciplining students. In one nasty scene she kicks a girl in the chest and dunks her head in a public toilet.
Unfortunately, the scenes often seem to be in slo-mo. Japanese porn, if this is typical, is much slower than ours, with more emphasis on kink, seduction and power games.
In the hottest scene Sakura dresses an androgynous boy in a schoolgirl outfit and fucks him with a black strap-on. Then he fucks her.
This is a quality product as far as videography and performances, but the languid pace takes some getting used to.
