Backstory according to the artist:

The girl with black hair asked her senpai to help her study... Her senpai came to her house willingly. But instead of giving her help, she knocked her out. The girl woke up only to discover herself tied up and helpless. Her senpai...has prepared everything and is ready to enjoy her.
