pencil and story: Jun Amamiya

The volume is in Japanese, so I can only guess the story.
The story tells of a student who wants to become a model and is helped by an already famous blonde model.
The girl has constant erotic dreams, but she has no experience in real life.
Try a particular attraction for a schoolmate, a member of the baseball team, but treats badly out of shyness.
A partner of hers, who looks a lot like her, is instead much more uninhibited and ends up having many more experiences than her.
The professional model begins a process of transformation of the young woman, both to make her more uninhibited at work and for more personal reasons.
The first step of transformation takes place during an underwear shoot in which they pose together.
The girl ends up getting turned on, wetting her panties.
At the end of the story, the protagonist is kidnapped by the baseball team coach, to rape her, but the volume ends before that happens.
