Touhou ~Record of Penis Viewing~

"Could you show me your masturbation?" A mysterious pretty girl introduces herself to a porn film director (the lead character). Her name is Yukari, and she says she is a specter and has been feeding herself with human body, but she intends to eat sperm instead as a main meal in the future. And for that, she looks for a man who has a good c*ck for that purpose. This is the first volume of the game and story continues to the next volume. This is a sound novel based on the characters of Touhou.
