A high school student, I've never had a girlfriend or even experienced sex—the perennial "unpopular guy." By chance, I come across a mysterious book claiming, "If you penetrate a woman 100 times, she'll fall in love with you." One after another, I violate four popular girls at school with my cock, filling them with creampie after creampie. Drowning in pleasure, the entire school becomes my harem. This is the story of a "fucking" guy.
