Tsubame Ameyori, who has a desire to be tied up, is tied up for the first time. A woman who is trapped, confined, deprived of her physical freedom with ropes and restraints, and writhing in fear. Being bitten by a gag and being unable to speak, asking for help, groaning, struggling, and suffering... A desperate pinch! You struggle desperately to escape from the rope, but the more you struggle, the more the rope creaks and tightens your body. The heroine, who is restrained in a sprawled manner and is all she can do to groan, shows a despairing and sorrowful expression. Comes with a bondage SM training bonus.
