"What the hell is this?!"

Kana — a high school gyaru — shrieked, after finding herself apparently trapped in "that room" that you often see in porn manga.

Inside the room was just her and an older man. Even while despairing over the situation she has been placed in, Kana accepts that she has to do something with this older man in order to get out. However, the man is hated by his daughter, he got fired from his job and lastly, his wife divorced him... and so he is uncooperative.

On top of all that, the worst thing about this older man is that his heinous dick has super late ejaculations!?
