Sneak into your best friend's sleeping room and have a happy ending

A rather unfortunate situation for the pretty girl Ninomiya Hikari. She was sleeping soundly, when suddenly a group of boys came into her room and committed adultery. By the time she knew, she was already naked. One swallow cannot create spring, so she had to accept being raped by a whole bunch of people. We invite you to look forward to how the story will develop!!
