BOKD-054 My lewd lower body is fully erect even though I can't move Yuri

Restrained and tied up, unable to move as he wishes, all of his holes are used without permission...but even so, Yuri's masochistic and lewd lower body keeps getting bigger and bigger. That's right, when a person's movements are restricted, they instinctively pursue only pleasure! Please enjoy Yuri, a femboy who has become very lewd and exposed to his true instincts.
