Kame is an unpopular, unemployed ass fanatic. His lonely childhood friend Ranka, a deeply tanned gyaru, comes over almost every day and makes herself at home. He never viewed her sexually until her huge ass gives him an erection and she catches him secretly jerking off. Unable to resist, he buries his face between her cheeks and ends up fucking her. She likes it far more than expected, leading to daily creampies from then on.
