ด้วยการควบคุมลมหายใจที่ยาวขึ้นและยาวขึ้นจนถึงจุดสุดยอด

Miss Kirsch and Miss Yara have trapped the slave Canvas in a leather sack on the bed. They begin to tighten the many straps to make the situation even more hopeless. From the start, the slave is wearing a latex mask with a small hole in his mouth and his breathing is already restricted. The mistresses begin to hold the hole shut and the slave struggles to breathe. One after the other, they sit on his face and work on his cock and balls at the same time. The slave can't prevent having his balls tightly tied and his cock jerked with steel wool until he reaches orgasm.
