Tomoko's breasts have grown rapidly since she was a child, and are now too large. She is depressed by the lewd gazes she receives from men every day. One day, she finds an ad on the internet for a suspicious salon that promises to burn fat and reduce bust size through a mammary gland massage using special oil, and visits it. However, it turns out to be a corrupt massage salon run by a perverted old man. The beautiful girl's breast erogenous zones are developed. Her sensitive 100cm breasts are kneaded and she pees in an embarrassing milky orgasm!
