The story of Yu, who came to Tokyo for college this spring, was starving for men. She had never even kissed a man, let alone had a romantic relationship. And yet, she had an unusually strong libido. Masturbation too. Even a longing for dicks. Because Yu had only been dedicated to sports, she had no masculine charm in her appearance, and was very… plain. But, she was amazing when she took off her clothes! After all, she has an L cup. A size you might not even see in a lifetime. This is a story about doing it with a neighbor college student who has a strong libido and big breasts.
