Aono Miku, a beautiful girl with long black hair and eyes as adorable as a small animal, undergoes adult discipline in this scenario. Her training is handled by experienced older men skilled in sexual techniques. The session begins with deep throat training. Miku, dressed in her school uniform, is tightly bound with ropes. Despite her fear, her mouth is pried open with fingers, and a thick cock is thrust deep into her throat. She lets out a loud sob, echoing through the room. This discipline drives her into a crucible of pleasure, eventually transforming the invasion of her throat into ecstasy—even as she repeatedly wets herself and convulses. Resembling a milk-drinking doll, she is led into a new realm of sensation, marking the beginning of her transformation.
