Then they have sex in a variety of uncomfortable locations in one of those montages that were a staple of erotic flicks back in the day. The guy, aware he has an audience, starts playing with his penis and apparently masturbating. The second story is about a man and a woman who return home on a date and shower separately while the other one watches.
I stopped paying attention and missed the ending, if it even had one, but I enjoyed the ease in which the girls were naked before the camera. One of the girls seems visibly older than the other, and I thought perhaps she was a teacher and not a fellow student, but the plot description indicates she was a student too. The first story is something to do with lesbian high school girls hanging out and having sex. It contains three stories of the erotic, none of which are particularly interesting, but which at least provide opportunities for the performers to get naked. The unimaginatively titled 'Porno' is a passable softcore romp from Brazil.
