pencil and story: David

I don't know who is hiding behind the pseudonym “David” but the style has something familiar, which I can't quite recognize.
Sally Fotter is recruited by a girls' boarding school to enter the famous Porkwarth school of magic.
In the school, students are divided into families, each with a particular inclination.
Her roommate Jenny is keen to explain the qualities of each house in detail.
The house of the breath of the dragon is the oldest and the oral tradition is fundamental to access.
The house of the golden rod, of which Jenny belongs, prefers the use of special magic wands, much appreciated by girls, but also by boys ...
The house of the "Backdoor of Hell" is controlled by the Dragonis sisters, the real masters of the school, who absorb magical power thanks to a ... particular penetration!
Sally will have to clash with the Dragonis sisters, managing to triumph despite being helped by Professor Black Snake.
I guess you don't have to explain what parody it is!
