[Synopsis]

One day, Eriito Sugiru (aka Elite-kun) is kidnapped while on his way to cram school and wakes up naked in a room with only a bed and a screen.
He thinks he's been kidnapped for money but a mysterious figure on the screen explains that the room is unlocked.
As he immediately tries to leave the room, a big, plump and lewd woman appears from behind the door.
The mysterious figure then tells him -- "If you have sex with this woman, you can't leave the room."
