[When the Plain Girl Next Door Takes Off Her Clothes, She Turns Out to Have an Unbelievable L-Cup]

Ui, who moved to Tokyo this spring to continue her studies, is starved for men. She's never been in love, let alone kissed a man, in her life.

But her sex drive is stronger than most.
She even masturbates.
She also has a fascination with dick.

Perhaps because Ui has always been focused on sports, she doesn't look masculine and is very...plain.

But when she takes off her clothes, she's amazing!
She has an L-cup, after all.
The kind of size you'll probably never see again in your lifetime.

This is the story of a man who has sex with his sex-crazed, big-breasted college girl next door.
