Kaoru, a female teacher who abandons her sacred duty and succumbs to desire. Bound by strict rules, she one day falls deeply into a forbidden relationship with her student. Her supple big breasts sway gently as ropes and violin strings entwine around her soft skin, gradually eroding her mind. The melodies she plays stir her inner lust, and as she closes her eyes, the lewd sounds that reach her ears slowly take control of her soul. A taboo tale where the pure beauty of music fuses with the shock of a depraved relationship.
