[Synopsis]

"What is this!?" screamed Kana, a high school gal, locked in "that room" often seen in erotic manga.
There were only two people in the room - Kana and the uncle.
Although Kana was despairing over her situation, she accepted the act with the uncle in order to get out of the room but the uncle, who was hated by his daughter, fired from his job and divorced by his wife,
was uncooperative about her wanting to leave the room.
To make matters worse, the uncle was an extremely slow-ejaculating man with a wicked penis!
