Stimulation of the breasts possesses a mysterious power to awaken deep-seated desires hidden within motherhood. The delicate balance of drawing a woman into that fleeting moment when maternal instinct and rationality begin to waver—guided through the act of massage—is the essence of this experience. Known as breast massage, this practice is a form of care performed by mothers who wish to enhance lactation and improve breast function. By carefully stimulating the sensitive zones buried deep within the senses, it gently loosens inhibitions and maternal restraint, naturally inducing arousal. The professional who provides this specialized technique is the midwife. A midwife is a certified specialist dedicated to women's health, supporting pregnancy, childbirth, postpartum care, female sexual health, and newborn care. Once referred to as "sage" or "jōsan-fu" (traditional birth attendants), modern midwives hold national qualifications and offer scientifically grounded care. In Japan, only women are legally permitted to take the national midwife examination, meaning male midwives do not officially exist.
