Yuina just wanted to be loved by a lot of guys and lead a freewheeling life. After her 20th birthday date, she and one of her boyfriends go to a hotel to celebrate with drinks. She never expected to see her other two boyfriends there, however. "I invited all of your boyfriends." While she's still in shock, they keep her from getting away... and end up having a four-way! Taking it from all of her burly boyfriends at once makes her climax countless times. Something's different about her usually loving boyfriends. They've all become absolute beasts, each more possessive than ever, full of love and hate, and eager for sex powered by pure love (?). This is the story of Yuina's punishment from all of her beloved boyfriends.
