Tsubame Amai, who has a desire to be bound, is tightly bound for the first time. Captured, imprisoned, and restrained by ropes and bondage gear, her body is stripped of freedom as she trembles in fear. Gagged with a muzzle, she cannot speak, and in this situation, she seeks help, groans, struggles, and suffers. In a desperate pinch, she desperately tries to escape the rope, but the more she struggles, the more the rope creaks and tightens around her body. The heroine, bound in a crucifix position, can only groan, and her face is filled with despair and agony. Includes bonus BDSM training.
