JSTK-027 Otoko no Ko Body Development Research Institute: Endure intense stimulation to the limit, and if you react, a punishment drill challenge awaits. Yuuri Hifumi

At the Body Development Research Institute, a cross-dressed young man arrives. After a consultation with the doctor and detailed questions about sensitive areas, the treatment begins. Using toys, they stimulate various parts of the body, including the ears, neck, underarms, back, and nipples. The pleasure leaves him fully aroused. The sight of him being overwhelmed by a thick vibrator and the doctors’ bodies, eventually collapsing into a dazed state, is striking.
