A sexy mission is issued to the noble investigator Ichika! This mission was supposed to be the same as usual for the battle-hardened girl... Ichika was captured after a fierce battle. My body is already tied up with the rope and I can't move. From there, the pleasure and charm began! Sobbing, screaming, and climaxing in the den of Eros! A purgatory of 0 questions to the point where you can't focus your eyes! Although she resists, the rough rope that digs in every time her body reacts gradually dissolves her reason... Will she fall into a pleasure vessel! ?
