Query: Good book

Adult black and white graphic novel. While the novel is titled "College School Girl", the girl seems to be more of a High School Girl, as she appears to be going to something that looks more like a high school.A school girl named Petra dreams about lesbian activities while asleep, and fantasies about lesbian activities while awake, and writes these thoughts in a diary. One day a new girl (Jennifer?) turns up at school and later joins Petra at Petra's home.After accidentally spilling a drink on the new girl's shirt, Petra wanders off to clean the shirt. The new girl reads Petra's diary and decides to take the opportunity to join Petra in some lesbian games. Their activity continues at school and includes a teacher.The drawing is ok, and the plot and character's are somewhat thin. Otherwise, not a bad book.
