Saki's recent problem is inheriting her mother's large breasts, which causes severe shoulder pain. However, her brother, who loves large breasts, offers to help with massages! Her well-developed breasts are too much for him to handle. Under the guise of massage, he rubs and kneads her breasts! Easily tempted, she unknowingly falls for his advances... Please enjoy her shy expression!
