It was inevitable that the 1970's naughty Schulmädchen-Report series of films (13 at last counting) would inspire some triple X variations. Some of the nubile and mostly blonde actresses even made the move from full frontal nudity to actual intercourse as their school years stretched on and on.
Fittingly, Schulmädchen Porno II features a lot of pretty young (but not too young) girls seducing their old and bald teacher Wallhaus to get better grades, trying out some sex partners and basically having as much sex in one day as humanly possible. For instance, they take a ride from a stranger, go home with him and even enjoy a bit of S&M with his dominating Mrs. when she unexpectedly arrives home early.
Over at the horse stables young lovers meet for a roll in the hay, only to find another couple has beaten them to it. Another pair repeatedly rendezvous in a lonely meadow where no one will disturb them as they have sex. And even the gym teacher isn't safe, as she is seduces by one of her male students while his classmates return from the shower and join in.
One boy who's got an extra job raking a garden is seduced by the next door neighbor who's got an bandaged arm. Afterwards she asks him to bring a friend next time. A bunch of girls go out into the woods to frolic around Oben Ohne (topless). Of course this is asking for trouble and soon they are surprised by some bottomless guys.
There's little plot at all in this installment, but certainly enough variety in participants, locations and positions. The final sequence takes place on the stairs at a girls house while her parents are having diner in the next room and near sighted grandma keeps walking up and down them.

Re Cast List, the creditted names (Marianne Kren, Inge Bold, Malte Rens etc) are all fake and were used only for this porno. Did detective work to get proper names when possible.
The original copy was nearly unwatchable. I have recoded to XviD, compressed the audio stream and resynced, adjusted HSV particularly saturation, improved contrast and sharpened picture, also repaired some bad frames. Picture quality is now about moderate VHS rip.
Played and tested on VLC, and WMP with K-Lite
