David

A physically attractive professional fashion photographer.

He is great at his craft and can take amazing photos.

He is in a mutually beneficial business relationship with Dr. Melissa Thompson.

Dr. Thompson sends him her client victims - that she is working on corrupting. He also has to follow Dr. Thompson's directions which reinforces the victim's sexual and mental corruption.

In return, he is able to take photos of these woman in more and more sexual situations and clothing. He is also able to have sex with the female victims once the victim's corruption is far enough along.

It is implied that he and Dr. Thompson have been in this beneficial business relationship for a while and he completely defers to Dr. Thompson's direction when dealing with the female victims.
